Wind Farm Back-of-the-Envelope Economic Analysis

Guest post by Larry F. Brown, PhD

We visited a wind farm in southern Utah recently. I’ve always been curious about the costs, profitability, and physical size of these things as well as the footprint and environmental impact. I had 3 meetings with the man in charge of maintenance of the wind farm, a landowner who leases land accommodating 4 of the turbines, and a man who works in the industry in Colorado – and did some internet/newspaper research.

The maintenance superintendent told me they have 27 towers, that the installation cost was about \$2 million each, and that each turbine is rated at 2.3 megawatts/hr but produces an average of 1.3 megawatts/hr (= 1,300 kW/hr). The blades are 187 ft long so the total height is nearly 400 feet high, and the tower at the base is about 13 ft in diameter encapsulated in huge quantity of concrete. The project pays about \$1 million in taxes to the community each year and has a 20-year lease.

A nearly 400-foot-tall propeller-tower is a very imposing structure, especially in close proximity. They are huge. They make a whooshing noise and the turbine itself makes a little noise. The propellers appear to be moving very slowly but the tips of the blades normally travel at 180 to 200 mph. The blades can ice up, which requires deicing (with electricity) and can throw ice a significant distance – hence each tower has a flying ice danger zone clearly labeled with signage.

I pay about \$.11/kWh for my electricity here in western Colorado. So, beginning the process of calculating the profitability of these things, each tower @ 1,300 kW/hr could produce an average of \$143/hr = which would be \$3,400/day = \$1,253,000 of electricity/year. Sounds good – so far.

[Note – Germany boasts about their renewable energy effort but Germans pay about \$.35/kWh on average – 3.3 times more than we do here in Grand Junction – and their rates can get as high as \$.50/kWh.]

The \$.11/kWhr I pay includes all the distribution costs, etc. The wind farm is not paid \$.11/kWhr for their electricity. According to the ISO Wholesale Power Market Prices, the electric company sells electricity for about \$.03/kWhr so instead of grossing \$1.253 million, they might gross about \$342,000 per year per turbine. Still sounds good – so far.

[The landowner indicated he gets a royalty for each tower that comes to an average of approximately \$1,000/tower/month and gets paid separately for the power line easement across his land.]

“BUT WAIT!” (- as they say on late night TV when giving you the hard sell).

All of that income happens only if the machines produce 24/7/365. They don’t. They need to be down for periodic maintenance and for when the wind does not blow the right speed. I don’t know what percent of the time these particular turbines produce electricity, but studies show the wind only blows the right speed (the wind can blow both too soft and too hard) 18 to 19% of the time on average across the country. 18 to 19 % of \$342,000/year = \$65,000. MMmmm, all of a sudden, the economics don’t look very good. \$65,000/year/tower is nowhere near enough to even pay the interest on a 5% loan to construct the tower \$2 million tower.

It gets lots more complicated when you consider that the wind farms are being subsidized by the government with the Production Tax Credit (PTC). A tax credit should not be confused with a tax deduction. A deduction reduces the amount of income you pay taxes on. is paying taxes on. A credit is money back. And the PTC is a “Refundable Tax Credit” which means the company does not just get to pay fewer taxes but actually gets paid by the government even if it does not owe any taxes.

The PTC subsidy has been in effect now for 27 years. Congress has adjusted the PTC many times through the years but today the subsidy is about \$.02/kWhr. So, the power company gets money back in the form of a subsidy for roughly 67% of what they produce – i.e., the company gets money back to the tune of \$.02/kWhr after it sells the electricity for \$.03/kWhr. If the company sells \$3 million of electricity they get the \$3 million plus a PTC subsidy of \$2 million. That is a huge subsidy! In fact, I think it is the biggest subsidy ever given for anything.

T. Boone Pickens and Warren Buffett both have huge investments in these things and both have openly said that wind farms would not be economic without the PTC.

Note: Now, if I were the company and using the above example, I would report a gross income of \$5 million. But, as a taxpayer, it’s more honest to say the wind farm has a gross income of \$3 million. It would be dishonest to include a subsidy as profit. So, my back of the envelope calculations will go on from here without considering the subsidy as income.

Note: I would be surprised if these wind farms pay any income taxes. Potential taxable income can be written off against the investment for many years – probably the life of the project – without even dipping into the PTC.

Then, I don’t know for sure, but I think the turbine manufacturers also are subsidized by the government.

However, the economics get worse – much worse. The maintenance man said the towers cost about \$2 million each – i.e., about \$54 million for the 27 towers. Each tower probably does cost \$2 million to install, but there are many other development costs associated such as land and right-of-way leases, power line construction, road construction, fencing, runoff control, revegetation, etc. Newspaper articles reported that this particular wind farm cost about \$130 million, which is about \$4.8 million per turbine. That means the income of \$65,000/yr/turbine won’t even come close to paying the interest on a \$4.8 million investment.

Note – According to the Wind Technologies Market Report, US wind turbine market prices in 2016 were just under \$1,000 per kilowatt, or about \$2.3 million for a 2.3-megawatt turbine (about \$1,000 / kilowatt). These turbines installed cost about \$4.8 million for a 2.3-megawatt turbine (\$2,087 / kilowatt). An offshore turbine project recently approved off the coast of Virginia is projected to cost \$25 million per megawatt (\$25,000 per kilowatt). Wow.

In addition, the turbines are very technologically sophisticated and require constant maintenance. For example, the oils used in the turbines are very temperature sensitive and, when the turbines are not generating power, they must be heated – with electricity. Various articles point out that, although they produce electricity intermittently, they consume it continuously. Whether the wind is blowing in the desired range or not, they need power to keep the generator magnetized, to keep the blade and generator assembly facing the wind, to periodically spin that assembly to unwind the cables in the tower and to balance the pressure on the shaft, to heat the blades in icy conditions, to start the blades turning when the wind is not blowing fast enough to keep them going, to keep the blades pitched to spin at a regular rate, and to run the lights, internal control and communication systems.

One article I read indicated that in a worst case analysis, these large wind turbines might use as much electricity as they produce. I don’t assume the worst case and just lump electrical usage in with the many other maintenance costs.

I assume the maintenance cost for this wind farm (manpower on call 24 hours, office rental, trucks/fuel, electric consumption, security, snow removal, replacement parts, etc.) to be at least \$750,000/year. Additional expenses of this particular wind farm (mentioned earlier) are the \$1 million paid in taxes to the local government and the \$1,000/tower/month) rent to the landowners. Together these 3 expenses add up to \$2,074,000/year = about \$77,000/turbine/year, so the income goes down from the \$65,000 to a negative \$12,000/turbine/year. For simplicities sake, let’s just call it \$0/turbine/year. Said another way, this project, according to this back-of-the-envelope calculation, makes no money.

Note: I tried two times to get the company to review these calculations. They did not respond.

And, all those materials (and permits and land leases) have a life expectancy of 20 years. What happens after 20 years? There is a wind farm in northern Colorado that is no longer producing, purportedly because the maintenance cost is too high to rehabilitate the turbines. The wind farm sits abandoned. All mining companies are required to bond for reclamation of a site when mining is done. I do not think this is true for wind farms.

Another interesting thing is that the dynamics of the power market are shifting. It used to be that peak power prices occurred during the day. Now they occur at night when solar is not producing. Thus, renewables are now generating when the prices are lowest in the diurnal power price curve.

The bottom line back-of-the-envelope conclusion of this economic evaluation is that these things are not even close to being economic.

And, environmentally, they kill birds and bats – millions of them. I used to wonder how this could be happening. The propellers seem to be turning so slow. But the propeller blades are so long they only appear to be moving slowly. The tips of the blades are actually moving at 180 to 200 mph. No wonder a bird can’t see them coming. And, apparently bats don’t even have to be hit by the blade to die. The way bats are killed is that the passing blade creates a vacuum and the bat’s lungs explode even if he doesn’t come into contact with the blade. And, yes, I know that cars and windows and cats kill birds but cars and windows and cats don’t kill eagles and falcons and other protected birds and endangered species, and cars, windows, and cats don’t kill bats.

And, the stupidest, most injudicious, most reckless thing of all is that the Obama administration granted permits to wind farms to kill birds and bats, including endangered species. All other industries are fined big dollars for killing birds – not wind power. Double Standard? How crazy is this?

Then, the coup d’état – The craziest part of this whole thing is that we must keep 100% of the fossil fuel plants operating to generate electricity during the 80+ % of the time the wind is not blowing at the right speed. Wow. So, what do we save?

We continue to build thousands of these things at a cost to the taxpayer of \$ billions/year. Why in the world are we doing this? I’m dumbfounded.

As indicated, each tower in this farm cost about \$4.8 million. Assuming a 5% loan, each tower would have to produce \$240 thousand per year to break even – i.e., even pay the interest on the loan. And, any normal investment would have to have some percent profit per year. I assume such an enterprise would have to earn at least another 5% per year as profit after taxes and interest to be a decent investment. That would mean that each tower would have to make \$480,000 per year. My calculation indicates they don’t make any real money. My calculations might well be wrong. They might even be wrong by a factor of 2. But I doubt very much if my calculations are off by \$480,000/turbine/year.

My conclusion: Companies are making money on these things, but the source of the profit is only (or at least mainly) coming from the Production Tax Credit – the subsidy paid by our government with our tax money for these projects. It’s obvious that T. Boone Pickens and Warren Buffett were right. Without the PTC (for the past 27 years) these things would not exist.

To make it worse, laws and regs have mandated electrical companies to produce x % of their electricity from renewable sources by such and such deadline. The renewables can’t make money so the electrical companies raise the overall price of electricity to cover these higher cost renewables. How silly is this? It’s very silly because the technology does not exist to store this electricity. Regardless of what Governor Brown or Governor Polis say or mandate, without storage, renewables will never replace other forms of electrical production.

The bottom line? A total waste of money – a total boondoggle – profitable to companies only because we, the taxpayer, are subsidizing them – and why are we subsidizing them? – because it’s green and it makes us feel good. And because a few “politicized scientists”, a whole bunch of liberal politicians, and the United Nations espouse that the burning of fossil fuels is causing global warming by adding CO2 to the atmosphere.

Well, we are indeed adding CO2 to the atmosphere by burning fossil fuels but CO2 is an insignificant greenhouse gas. CO2 has increased from 0.028% to 0.041% of the atmosphere (an increase of 0.013% percentage points) in the past 140 years. The theory says man’s 3% contribution to the 0.013% increase is causing global warming. How could only 3% of that minuscule 0.013% (i.e., a component comprising 0.00039% of the atmosphere) cause global warming? It can’t. Even more absurd, we are supposed to believe that taxing and selling carbon credits for that 0.00039% of the atmosphere will curtail the warming, slow the ocean level rise (as Obama promised), and save the planet?

It’s nonsensical. CO2 is not a pollutant. CO2 is a fundamental requirement for life and the added CO2 is actually greening the planet – vegetation worldwide is growing about 20% faster and using less water than it was because CO2 is a fertilizer for plant growth.

I think we should stop building these wind farms — tomorrow.

It gets worse!

Matt Ridley did another beer matt calculation some time ago and found that simply to keep up with the 2% annual growth in demand until 2050 (from memory) humanity would require an area half the size of Russia.

That’s almost the entire continent of N. America (excluding Canada) of wall to wall wind turbines. None of which addresses our existing energy needs.

The material required are simply mind boggling.

As usual a short, clear article from Matt approaching the subject from a slightly different angle. Add these two together and we can just begin to understand what is being proposed.

I like your “beer matt calculation”!

I really wish we could get to grips with the mindset that says “wind farms would not be economic without the PTC.” If it needs a subsidy no matter what it is then it is not economic. And that’s an end of it. If we stopped pretending that wind/solar could ever be economic at grid scale but that they have potential for niche generation then we might restore some sanity.

But to do that we need to expose the eco-scam for what it is and get the message over that the objective behind demonising CO2 has nothing to do with climate and everything to do with putting an end to civilised society as we understand it. And the activists, whether AO-C and her followers in the US, or Extinction Rebellion in the UK, or the devotees of St Greta just about everywhere, have stopped pretending otherwise if only we would listen.

1.3 megawatts/hr (= 1,300 kW/hr).

What the hell kind of quantity is measured in megawatts/hr ?! You should have done some more research to understand the basics of the subject. You could have saved yourself a few beer-mats.

I stopped reading at that point since if someone has so little understanding, I can have no confidence in their conclusions.

If you’ve never heard of Watt-hours before or why it’s used when discussion production of electricity, then you have no business questioning Dr. Brown. I’ve seen it written many ways, but technically it is W/hr since the measurement is Watts per hour. For millions of Watts per hour I would have used the MW/hr notation, but megawatts/hr, while being a bit nonstandard, is not wrong.

Rich Davis
July 21, 2019 1:04 pm

Sorry Paul, a watt is a unit of energy per time, a joule per second. It is a rate of energy production.

The watt-hour that you mentioned is a unit of energy, equal to 3600 joules. (3600 sec/hr)

A watt/hr on the other hand, would be a rate of change in the rate of energy production, something like an acceleration is a rate of change of a velocity, which was obviously not what the author intended.

Greg is right that this basic engineering error detracts from the credibility of the post, but then again, one does not need to master the physics or engineering to calculate costs and see that wind power is a crony capitalist boondoggle.

July 21, 2019 3:26 pm

For millions of Watts per hour I would have used the MW/hr notation, but megawatts/hr, while being a bit nonstandard, is not wrong.

Millions of watts per hour has no meaning in the context Larry Brown is attempting to use it. A watt is a unit of power (energy per unit time). Power divided by time only has meaning when discussing how quickly power plants can respond to changing load demands (e.g., if a power plant is trying to perform “load following,” it might “ramp rate” up or down of X or Y megawatts/minute, or MW/min).

The wind turbines are rated at millions of watts (megawatts), which is their power rating. Larry Brown should have been using megawatts, not megawatts/hr. The turbine is rated at 2.3 megawatts, but produces 1.3 megawatts averaged over time (typically capacity factors are expressed as annual averages).

Larry Brown is correct. Even though production figures are usually quoted in the same units as consumption figures (ie MWh or kWh), The units megawatts/hr and kilowatts /hr can be the final generating production amount averages. More usual is that the maximum capacity number is quoted as just megawatts. But this is misleading because maximum capacity is never achieved. Power itself is in megawatt-hr or kilowatt-hr or terawatt-hr… etc. However there has to be a way to represent how much electricity is actually generated by the power plant per hour.

However there has to be a way to represent how much electricity is actually generated by the power plant per hour.

I have seen units like MWh/year and used to document the energy production over an entire year, the idea being it smooths out the summer doldrums and winter winds.

What units of electricity do you want to use? Volts and amps are best, but rather meaningless except to determine insulation and wire gauge. Power plants usually are rated in watts, usually millions of watts. A pretty large fossil fuel plant is typically 1,000 MW. Typical wind turbines have a peak (or faceplate) rating of 2-3 MW. So you’d need about 450 turbines running at full output to match a natural gas or nuke plant. The latter average about 90% output, with a lot of down time that can be scheduled. A wind turbine has a typical load factor of 30% and is at the mercy of the weather.

Curious George
July 21, 2019 1:41 pm

A kilowatt/hr means precisely nothing – strictly speaking, it means that the person using it has a rather inflated opinion of her/his IQ. A kilowatt has already a “/hr” built in. Likewise, a “knot” as a measure of wind speed, has a “/hr” already built in. I avoid sailors who talk about knots per hour.

Curious George – so he used the slash instead of a dash as a separator because he thought it was just that, a separator. I suppose the lack of any ‘rate of change’ in his discussion confused you so greatly you blew a fuse while the rest of us understood him perfectly. IQ is both a measure of ability and the potential to understand. Are you living up to your potential?

Greg
July 26, 2019 9:55 am

megawatts/hr and kilowatts /hr can be the final generating production amount averages.

NO , that would be megawatt-hour , it’s a total energy production, this is usually stated over a year, so comed back to being an average power term in MWh/year.

Many people commenting on this need to talk to a Electric Utility Electrical Engineer.
The 2.3 MW turbine is the Name Plate Rating of the Turbine/Generator – That is its MAXIMUM load is 2.3 Megawatts. Period. Use above that is over loading the Turbine/Generator, however some slop is allowed. Specification provided by the manufacture will detail this slop. Typical condition such as +/- 5% over some period of time, +/- some ambient temperature, 0.0 VAR +/- 5 VAR, the rated out put voltage +/- 5% etc. That rating is basically determined by the current capacity of the windings. Heat generated by the generator and the cooling capability of the cooling system also factor into this number.
However, the devices measuring this magic number measure usage per hour. Once upon a time to measure the LOAD on the generator the used a mechanical watt meter. These were basically a synchronous motor that had wingdings for the line voltage and the line current. One revolution of the disc [the rotor] was 1 watt of power used. 2,300,000 rotations would be 2.3 Megawatts.

Malcolm Carter
July 21, 2019 1:36 pm

Greg – You are too quickly dismissive of an argument for a misunderstanding of units. A quick rereading and you realize he should have used MW and that the turbines are usually outputting about have of their rated power, then later he states that the turbines are producing this half power for less than 20% of the time. 0.5 * 0.2 = 0.1 * their rated energy. The thesis is about the unsustainable economics of sustainable energy and it largely works.
Yes his arguments could use a scientifically alert editor but the approximations are probably close.

July 21, 2019 3:40 pm

The problem is that a capacity factor of 10 percent is absolute nonsense for 2.3 megawatt turbines installed in Utah. A capacity factor of 50 percent is much more reasonable (i.e., averaged over the entire year, the turbine produces 50 percent of what it could if it was operating at its rated power of 2.3 megawatts all 8760 hours per year).

Dave Fair
July 21, 2019 4:03 pm

A well-sited wind turbine will get about 30-35%, IIRC.

July 21, 2019 4:11 pm

I should have checked more carefully. Utah is a lousy state for wind power. A capacity factor of 25% is more reasonable, even for a wind farm with 2.3 megawatt turbines.

A wind plant in Costa Rica with which I am quite familiar is sited on what many consider one of the most perfect sites for continuous strong (but not excessive) wind conditions. The capacity factor was only about 40% on an annual basis. I believe the taller towers and longer blades might help the newer plants boost their capacity factors a little, but the wind profiles are surely less than optimum. So a 35% CF would be reasonable. I suspect the “Maintenance man” was just mentioning a power level he frequently saw and not a value ‘for the books’. So the 2.3MW rated units were probably producing about 2.3*0.35*8760 = 7052 MWhr annually. At a grid price of about \$22/MWhr (a reasonable guess at an time-weighted average) the gross income would be about \$155,000/turbine/year.

July 22, 2019 11:24 am

From Dave Fair:

A well-sited wind turbine will get about 30-35%, IIRC.

From Roger Morgenstern:

So a 35% CF would be reasonable.

Per the EIA, this if this facility is the “Latigo Wind Farm,” it had acapacity factor of 28 percent in 2017.

https://wattsupwiththat.com/2019/07/21/wind-farm-back-of-the-envelope-economic-analysis/#comment-2750429

That’s a lousy capacity factor for a wind electrical production facility with such large (2.3 MW) turbines, and the primary reason is because Utah is a pretty lousy state for wind. Even as early as 2012, capacity factors for whole states were above 40 percent…and that was with much smaller turbines:

Nicholas McGinley
July 22, 2019 12:53 pm

I passed by the first few errors, but when I came to this…

“I assume the maintenance cost for this wind farm (manpower on call 24 hours, office rental, trucks/fuel, electric consumption, security, snow removal, replacement parts, etc.) to be at least \$750,000/year. ”

…I realized that this was not a truly serious effort by someone who was really trying to account correctly.
Why should anyone assume some one can assume how much maintenance costs, when his personal knowledge, as stated at the outset, consists of a few conversations with a couple of people?
We all know these things are a waste of money, and a tax giveaway, and a crony capitalist wet dream, and have seen many very well detailed efforts to point this out.

1 watt equals energy transfer , or power, of 1 joule per second.
1 megawatt equals 1,000,000 joules per second.
Formally a megawatt/hour would have to be a measure of increase in power over time [1 hour], acceleration.

Informally a megawatt/hour could have been meant to be a measure of continous power production. If so it should have been written as megawatt hours or more correctly megawatt-hours.

“The production of power over time is measured in megawatt-hours (MWh) or kilowatt-hours (kWh) of energy. A kilowatt is one thousand watts. Production of power at the rate of 1 MW for 1 hour equals 1 MWh of energy”.

If the error was made in an article promoting the benefits of wind energy I somehow think you’d pass it off as ‘neglible to the overall facts’.

Having just watched the British Open golf tourn. (congrats Shane Lowery) at Portrush, N. Ireland … I wonder why there are no wind farms covering the countryside at these posh golf clubs? Why are the wind farms, err wind factories built in the hinterlands where the poor people have to stare at them? The wind famously blows a gale (constantly) at the posh golf clubs. Indeed, the WIND is considered an integral part of the “charm” and challenge of the British Isle golf courses. I say let’s build all the eco-elite’s virtue signaling wind towers covering the countryside at St Andrews! Let the entire world see just what these contraptions do to the natural, scenic environment. How about despoiling a few posh views and see what the eco-hypocrites think of their “renewable energy” virtues.

July 21, 2019 4:37 pm

Kenji (July 21, 2019 at 11:54 am) it is not true that

…the poor people have to stare at them?

because, whenever outside, the poor people, just like the wealthy people, should be staring at their mobile phones. Unless driving a motor vehicle, in which case they should be staring at the road and barely discern the beautiful technology in their peripheral vision.

I’ve driven my BIG gas guzzling V8 engined Land Rover (12 mpg) throughout the far reaches of the American landscape … on sparsely traveled roads … where I encounter beautiful vista after beautiful vista blighted by these gawd-awful wind factories.

You should know that I NEVER text and drive, and I practice “high aim steering” (because I’m an excellent driver) which focuses my eyes on the horizon, not on the macadam under my front wheels. So, these inefficient contraptions are always in my field of vision. And they’re awful.

The old-timer “environmentalists” opposed construction of our HV transmission lines based on their impact to scenic areas. With the lack of serious opposition to massive industrial wind installations, I wonder if the old opposition was just political in nature. [N.B. Always use “massive industrial wind installations” instead of wind farms” when conversing with the woke.]

Some of those old-timer “environmentalists” are indeed coming out against wind power, it generally depends on whether such “massive industrial wind installations” are in their particular back yard or not though.

Although, on this occasion, I’d tend to agree with Bob Brown (something that happens somewhat infrequently). It would be a pity to blight the magnificence of NW Tasmania with these useless contraptions.

Well Kenji well put.
First of all those of us familiar with Ohms law, will excuse the terminology to describe the utter folly of wind mills to give them their proper name.
They would not be feasible without the taxpayers payments either in raised electricity prices or naked subsidies.
Now Mr Kenji you have touched a raw nerve with me.
You see I live in a nice second floor apartment overlooking the Bell Rock Lighthouse in Carnoustie bay.
We hosted the Open here last year which Franc Mollinari won.
Just last week an (Irish) company who are into this windmill boondoggle tell us they have put a compulsory purchase order on part of the public/golfers car park and several acres of our golf courses to facilitate the land fall and infrastructure of the electricity cable of the vast array of dozens of bird killing windmills which they WILL be building in my line of sight, right in view of the next open golf championship to be held here – and across the bay at St Andrews in two years time.
So whilst I agree it should be a no brainer to build there blots on the landscape close to or right on top of where the unreliable power is used – say next to the houses of parliament or congress –
the chances of that happening are aken to this other Irishman winning the next Open.

July 22, 2019 10:13 am

Good challenge. However you would be more credible if you used power versus energy accurately. Please go through your article and fix your units, distinguishing between power and energy. e.g. fix “2.3 megawatts/hr” to “2.3 MegaWatts.” but produces an average of 1.3 megawatts/hr (= 1,300 kW/hr).}
Power in watts W is rate of energy / time i.e., joules/second J/S
Energy is the product of power and time. e.g. joules = watts * seconds.
kilowatt hour is watts times hours. kWh = W * hr.
“if the machines produce 24/7/365” to “if the machines produce 24 hours/day * 7 days/week * 52 weeks/year or 365 days/year or 8760 hours/year
(actually 365.26 days/year or 8766 hours/year)

Exactly so.

There is a web site, Do the Math, which has done similar calculations for many aspects of renewable energy. The conclusion is the same. Renewable energy is, by calculations a grade school student could do and understand, a boondoggle. You really have to have a lot of education to believe otherwise. (Note, I did not say well educated. There’s a huge difference.)

My own back-of-the-envelope calculation for solar PV indicates that the usually published and accepted cost figures are junk.

Fossil fuels are an incredible bargain. They have enriched us to an extent that our ancestors could not even imagine. So far, this is the golden age of humanity. The greenie postmodern Marxists do not come close to understanding that, nor are they in any way the least bit grateful. They, as a group, are a bunch of out of touch, entitled, spoiled brats.

The general public neither understands nor enjoys math. In fact, they quite despise it … as the one class in school that routinely humiliated them and harmed their chances of acceptance to our “top” Universities, err indoctrination factories. So any and all math calculations will be sneered-at and claimed as propaganda of the conservative fringe EXTREME denier community. The vast majority of Socialist aficionado global Warmists will dismiss and/or ignore any math proofs.

This is not a joke. A few semesters back, I got the fun of teaching a Practical Math class, even though I have no advanced degree in mathematics (they couldn’t get anyone else to teach it, but since I knew the materials and had a mentor to check over me, the college was ok with it) >

I literally went in there and started talking about the “A” word (algebra) and had to start referring to it as such to get the students to relax down enough to move through fractions and stuff, to where I could spring it on them about 3/4 of the way through the semester that they were indeed learning Algebra, and that a lot of stuff you would use in trades every day is just that… I had one person get completely bent and stomp out and cuss at their advisor over it – but the end result was they came back and earned their grade – These aren’t dumb people, these are people going after technical certifications and associates degrees to go work in the world – but they were almost to a person absolutely terrified of math…

I keep wondering what our society is doing to people to make them act so dumb in not in their self interest.

It ia slso true that ALL the materials needed to manufacture Wind Turbines and Solar Panels are Finite and that getting the ores out of the ground utilizes the same Open Pit mining that Coal utilizes so can be just as environmentally detrimental.
There will come a day when an alternate source of energy is derived that will cost less than Fossil Fuels (sa that time), It is only then that High Density Fossil Fuels should be replaced and market demands would cause their replacement with less costly energy sources. But forcing the replacement by artificially inflating the price is idiotic as is forcing a modern society to utilize vastly unreliable weather dependant energy sources.

Nicholas McGinley

The main point to be made here is that wind turbines are not able to make enough power to support an economy. You could not even build a wind turbine using only wind power.
Imagine if it was impossible to mine coal or drill and pump oil using only fossil fuel power?
They would be useless as a basis for energizing an industrial revolution, and thus we would not have had one.

Wow, Nicholas! That is almost a ‘Wrath of Khan’ moment (“From hell’s heart, I stab at thee. … I spit my last breath at thee.”)

But, I don’t blame you for going off half-cocked given the zeal of some of the more rabid so-called skeptics and the short-sighted naysayers that Mills has encountered over the years. But rather than ask for clarification on a point two you ‘launch’ based on ONE small facet out of quite a large number events and lab demos and that have taken place since 2016 (AND not all of those have been are to the public. Oh, to be a fly on the wall of a BrLP board meeting.)

Now, why should I bother answering in any manner, way, shape or form, Nicholas? CLEARLY you’ve made your mind up based on very little, AND PROBABLY BADLY DATED information. A lot has taken place at BrLP since 2016; the “reaction rates” have gone off the charts, no more is the reaction rate limited by certain inherent ‘factors’ as it was with the electrolytic cells Mills worked with years ago.

BTW, dear Nicholas, what does determine the “ground state” in the hydrogen atom? Have you any better ideas than QM/QED (Quantum Electro-Dynamics) that work out so elegantly in the maths and in experiment? Recall even the great Steven Weinberg now expresses his doubts about QM and its basis:
“Steven Weinberg on What’s the matter with quantum mechanics?”

Nicholas, your ‘opinion’ above should be weighed against the veritable mountain of evidence existing to the contrary of said ill-informed opinion. Do you need reference, here and now, Nicholas, to that veritable mountain of evidence? Or are you now now so ‘steeled’ in resolve against new evidence to a (subtlety, not entirely radically) different universe and atomic structure that new info would run ‘off’ your mind as if “watering concrete’?

In any case, I’ll throw you a ‘bone’ – the lecture by Mills at Fresno State University; this is as good a place as any to ‘come up to speed’ if you can overcome an obvious negative bias that is unwarranted (but most likely due to the ‘bad vibes’ generated by the likes of Bob Park of the APS as well as a few notable others a decade or so back):

I will not even bother to comment on your assumptions about what I do or do not know, or what is the basis of my desire to see some proof, or of my skepticism.

The “market” will take care of it.
As fossil fuels are depleted prices will rise and energy user will search for other cheaper sources of energy. If wind, sun and water can supply energy at prices that are affordable for industry then they are the sources that will be used. If nuclear can do the job better then nuclear will be the source.

If fossil fuels become too expensive for industry and wind, sun and water prove unreliable and if societies choose not to go nuclear then metals and iPhones will be reserved for the rich.

I think it’s important to add the infrasound noise problem that has become a much bigger problem with the newer HUGE wind turbines.

Infrasonic noise is difficult to measure, and many people, perhaps most, are not sensitive to the noise.

As a person who is sensitive to infrasound, I was shocked to find out it can travel ten miles from the wind turbine, in all directions (low frequency noise is omni-directional, and not measured properly with a conventional A-weighted sound pressure meter).

The last of my two June 2019 articles on the subject, which deserves a lot more attention in the mainstream media, is at the link below:

She has stated publicly that knowing what she now knows about wind turbines, she would not live within 20 km from wind turbines and yet people in rural Ontario have their homes surrounded by them in close proximity.

Unbelievable! Let’s start first with the correct evaluation of Cap.Factor. this is machine Name Plate Rated Capacity x site specific factor on how much of that capacity you can achieve. Land based wind (cheaper then offshore to construct but lower factor) avg uses 40% in a worthwhile site.
You don’t get to double negate by then saying 15% of 56%.
All the other pisspoor assumption are candy for the fraud eaters in this audience. You don’t have to go far to get real numbers and check thier authenticity. Lazard’s levelized cost of energy (LCOE) includes construction costs, capital costs, maintenance, fuel, etc. For each form of energy generation: nuclear, coal, simple cycle gas, combined cycle gas, wind, hydro, pv. Both subsidized and un. Decommissioning costs of nuclear, coal Ash and mining slag pits, NOx and SOx damage costs, wind bats and birds, and other idiot bate on both sides is not accounted for.

Per the EIA, the average annual price for natural gas to electric utilities for the four-year period from 2015 through 2018 was \$3.38/MMBtu. So \$3.45/MMBtu seems very reasonable.

I strongly doubt that. It would mean a duty factor of 56.5 % which would make it just about the best on-land windfarm in the World. I have visited southern Utah a few times and don’t remember it as an exceptionally windy place, much less than e. g. Wyoming for example.

Watts = power = energy/time
Watts/time = energy/time^2

No, when talking about electromagnetism, the Watt is not defined as a unit of work over time. It is an instantaneous measurement of power. For DC it is Volts X Amps. It’s a little more complicated for AC, but time still is not a factor. Watt-hour, usually written as Whr (and sometimes mistakenly written as W/hr) is a measurement of electricity production – how much is produced per hour. I’m sure the OP meant MWhr when they said megawatts/hr. So this is really just nitpicking.

I took that line to mean though the max rated capability is 2.3 mW the average when the wind does blow is 1.3 mW obviously the wind sometimes doesn’t show up at all, so those days it is zero or more correctly negative due to system consumption of grid electricity.
The UK monitoring suggests turbines generate roughly 32% of the time available. I suspect Utah is similar so 1.3 mW average generation 32% of the time would be my guess.

And, why is their continuing emphasis on the rated power of these machines. Is rating of the machine irrelevant? It’s really doing a simple calculation based on wind data collected on site, say for year or more, to find out the amount of energy available to be taken? It’s like bragging about the 350 cubic inch V8 that’s rated for 195 HP … but you feed it with waste vegetable oil instead of high octane gasoline.

Interesting to know the rating of the machine(s), but more important is how much on an annual GWh/year is “presented” to the wind farm vs. how much GWh/year does the wind farm produce (or be planned to produce).

In my salad days when i was yet green, only the most exotic sports cars made 1hp/cu.in. The 1957 Corvette could be ordered with a 283 cu.in. engine that made 283 hp., by some strange coincidence. The Mercedes Benz 300SL 3 liter (183 cu.in.) 6 came in 2 flavors, one with 215 hp and one with 240 hp.

Today, those figures would not get a glance. Speaking of Corvettes, the 2020 type C8 corvette will come standard with a 495 hp 6.2 l ( 378 cu.in.) that will propel the vehicle to 60 mph in less than 3 seconds. But, Honda sells a version of the Civic with a 2 l (122 cu.in.) engine that gets 316 hp.

We need to invent a new unit of power for rating wind turbines.
I propose a new unit which I am gonna call “1 jp”

read as “One jackass power”, it is the amount of power a wind turbine is rated at by the liars who build and fund them, divided by the failure rate of the turbines times the departure of actual lifetime from advertised lifetime times the amount of time they spend doing nothing but looking ugly times the number of birds and bats they kill per hour times the actual amount of power they put out during the time it is windy enough but not too windy to make some power times a constant, which represents the inefficiency with which politicians waste taxpayers money when they have anything to do with a project or industry.
(The unit called “one jackass power” likely will need some modifications when more time and effort is put into properly accounting for all of the ways money and resources and energy is flat out wasted by these things…so feel free to add your own correction factors below)

I would not be a bit surprised if these things came with a very high number of jackasses, but who were not around when it really mattered and someone might have made some use of them.

Your “simple calculation” generally requires a permit for a “meteorology tower” and here in New England making a road to the ridgeline when you want the wind turbines.

Neighbors who know what infrasound has done at neighboring wind farms will invest a lot of time to block those permits!

The rated power is important, as there is a wide range of wind speed where the turbine will produce the rated power. Below that, generation varies with the cube of wind speed.

See for a few curves from Vestas turbines.

In addition to the rated power, the “capacity factor”, the percentage of the faceplate ratiing that is produced on average is equally important.

Van Doren
July 21, 2019 1:51 pm

German onshore wind farms have on average capacity factor of 16-17%. Offshore a bit more. Installing 1MW costs 1,567,000€. Operation costs are roughly 40,000€/a*MW. Land lease costs 30-100k/a per wind turbine. Plus taxes, plus conventional backup. All these amounts to roughly 0.16€/kWh.
I did a lot of calculations few months ago.

July 21, 2019 6:14 am

Not only those aspects, but a real analysis has to have accurate info on long-term maintenance costs and mechanical lifetimes. Ex. — how long does a pinwheel last before maintenance/repairs are no longer economical? I know these numbers are put into analyses, but I’d bet they’re way overly optimistic.

Everywhere you mention “megawatts/hr” and “kW/hr” it should be MWhr and KWhr. You are talking about energy (power * time). What you’ve written is power per time (power divided by time) which is meaningless.

Robert Keon
July 21, 2019 3:08 am

My initial response was a knee jerk reaction to seeing the nonsense parameter of “megawatts/hr” and “kW/hr”. On further analysis I see he is actually talking about power when he gives those parameters. Hence just drop the “/hr” and it will make sense.

Tom Johnson
July 21, 2019 4:54 am

I give the author the benefit of doubt on this one. Say you have a 100W light bulb that you only turn on at night, over the course of the year, it burns an average of 50W continuously per year. Since you are averaging per unit time, you might express that the same way. Hence, the “per hour” rate. It would be just as accurate (or inaccurate) to say “per year”, or “per week”. The rate term is simply a way of expressing that averaging has taken place.

‘The blades are 187 ft long so the total height is nearly 400 feet high, and the tower at the base is about 13 ft in diameter encapsulated in huge quantity of concrete.’

Anyone idea of the actual amount of tonnes of concrete each tower needs for its base and what that equates to as a depth of foundation? 10 feet of concrete the width of the tower? 20 feet?

tonyb

Eric Stevens
July 21, 2019 3:41 am

The base is bigger than the tower. It has to be to prevent the tower capsizing. How much bigger depends on the local soil condirions. Its a huge weight of concrete and steel, the production of which gives rise to substantial quantities of CO2.

Leo Smith
July 21, 2019 3:58 am

I think its around 1500 tons per wind turbine

“Lafarge provided Type I portland cement from its Paulding plant to Irving Concrete of Ohio, which built a strategically located portable ready-mix batch plant to produce approximately 122,500 cubic yards of concrete for the project. The construction of 15- to 20-foot-deep concrete foundations to support all of the 328-foot-high towers with 2-MW turbines required 30,000 tons of cement.

On average, each of these below-ground support systems used 60 truckloads of concrete (750 cubic yards)”

https://www.forconstructionpros.com/concrete/article/10886050/ohios-first-largescale-wind-farm-uses-lafarge-cement-for-turbine-concrete-foundations

750 cubic yards @4050 lb cu yard is 1356 tons per turbine

Samuel C Cogar

It is not just concrete…that is steel rebar reinforced concrete.
And it appears to be a very large amount of steel rebar.

( Hey, I wonder if one has ever fallen over due to soil weakening from flooding, or liquefaction due to earthquakes, etc?)

&exph=268&expw=400&q=Wind+Turbine+Foundation+Failure&simid=608012349886696298&selectedIndex=5

In any case, where these things are built, an enormous amount of construction prep work must be done before they can even begin to lay the rebar to reinforce the concrete.
It takes a lot of heavy equipment to do these things, so first a road must be built and with that a power line installed in a right of way. Then aa huge hole is excavated, and the hole prepped with several feet of crushed and compacted stone.
All of this is done by a whole bunch of people who must drive trucks to the site, and by huge machines that burn a huge amount of fuel.
Then many tons of steel is erected to reinforce the concrete and then the crete is poured.
It is a huge project and a very large undertaking in itself, and the foundation is very large, although not as big as one might suppose based on the height and width of the turbine.

@tonyb:

The US Government funded studies a decade or so ago regarding the estimated amount of steel and concrete required per TW of peak wind capacity installed. You should be able to find them with an internet search. Of course, the production of steel and concrete (as well as of the composite blades) happens to be very dependent on fossil fuels. As pointed out in the article, several back of the envelope studies have been done regarding what a massive investment in solar and wind power (e.g., in order to achieve some arbitrary percentage of electricity produced by so-called “renewables” by some arbitrary date such as mid-century) would mean in terms of long-term commitment to fossil fuels.

I recall several blogposts by a Tasmanian professor who happens to be a promoter of nuclear power plants, from several years ago. He demonstrated how poor such projects actually perform.

I did a survey of installed wind farms in several countries and came to the conclusion that a typical wind farm requires 2-3 orders of magnitude more land area than a typical thermal power plant for the same nameplate capacity (the mean value was approx. 400 x as much land area). Overall, land-based wind farms don’t achieve better than 20% capacity factor, either.

Plus, the more wind capacity you have installed, the greater the probability will be that the wind farms will produce electricity exactly when you don’t need it (market value = zero); conversely, it does nothing to provide electricity when you need it.

This doesn’t even look at the obvious upkeep costs or the service life of 20 or so years, nor the re-naturization costs if the site were to be abandoned at some point in the future. Nor does it look at the propensity for slaughtering airborne wildlife.

The arguments for investment in solar and wind “farms” dwindle to zero once the massive government subsidies evaporate. That which is not economically sustainable can not be called sustainable, period.

Shout if you can’t find any of these reports I mentioned. I may be able to dig some up for you.

TonyL
July 21, 2019 4:40 am

A quick search gave some numbers all over the map. Not really surprising as this will be site dependent.
Here are two:
Top of Iowa facility: 13 tons steel, 360 tons concrete.
Buffalo Mountain, Tennessee: up to 7,000 tons concrete. (no mention of steel)
Base depths were also all over the map, with some sites going up to 30 – 40 feet.
(concrete density 145-150 lbs./cu. ft., giving 2 tons/cu. yd.) {curious, most of the measurement units I saw were English, little metric}

and that each turbine is rated at 2.3 megawatts/hr but produces an average of 1.3 megawatts/hr (= 1,300 kW/hr).

Sorry but that makes the rest of the article junk.

Unless he is lying to the government about how much electricity he produce.

Ed T
July 21, 2019 3:17 am

I’m no fan of wind farms, they should more accurately be called subsidy farms, but I think you’ve double counted the capacity factor. An average 1.3/2.3 would be an exceptionally high capacity factor of 56.5%, but taking 20% of 1.3MW output would be a remarkably low capacity factor of 11.3%.

For a back of envelope calculation a 30% CF is a reasonable starting point, i.e. averaged annual power output 0.69MW per tower. Still end up with subsidy farming.

Could be worse, you could live in the UK where scotland has 15GW installed and approved development planned; 5GW peak local demand, and about the same in grid connection, so all uk consumers will be paying for 5GW constrained generation when the wind blows.

The thrust of your article is eminently credible ………as a player in the renewables sector we too recognize the degree to which the ‘Green Agenda’ has been cynically hi-jacked by many corporates in an attempt to buff up their halos……..while not losing sight of the bottom line of course.

Even though we are based on the African sub-continent, many of the financial metrics you describe in your article replicate closely with our local experience ………. in both the financial and certainly the environmental fields, the nett contribution of Big Wind to local economies is less than – or close to – zero.

I would only caution you to handle the CO2 argument with care …….. though in absolute terms the atmospheric ppm increase from .028% to .041% in CO2 is miniscule – in relative terms it represents an increase of around 50% over the past 140 years and correlates closely with our industrial expansion in the West.

To minimise the impact of this increase in CO2 – which is clearly an aberration if one accepts the record over past millennia given here https://www.2degreesinstitute.org/ – your point is being undermined.

Forget all your numbers, just tell me what the word “average” means! If a device “rated” at 2.3 somethings produces an “average” 1.3 somethings, then does that mean sometimes its output is 2.3, and sometimes its output is 0.0, but, over time, it “averages” out to 1.3? Or are you saying that, when operating at optimum, some of the turbines produce 2.0 and others 1.0, so the “average” optimum output is 1.3? You seem to have adopted the second definition of “average” while other posts have used the first.

Larry Brown
July 21, 2019 10:09 am

hiskorr – I am only reporting what was told to me in the interview. I believe it means that machines cannot produce with 100% efficiency and that these trubines purportedly produce only 1.3 instead of the designed (nameplate) capacity of 2.3. Other commenters inform me that the 56+% capacity factor is way high, which would make the economics even worse.

ED T
July 22, 2019 5:12 am

Larry,

You’ve assumed they only produce 20% of the time to come up with a nonsensical CF 11.3%.
0.2 x (1.3/2.3) = .113.

If the turbines can produce power in sub optimal conditions 53% of the time they can achieve both a 30% CF and an “average” of 1.3MW.
0.53 X (1.3/2.3) = 0.3

Better calibration of a real CF would be available from local wind farms, however with the caveat that older technology will likely have lower CF.

The income and economics stack out when the subsidies are included, which is why the things are getting built.

These blights on the land and economy (wind turbines) would unlikely be useful if there were a Carrington event or an EMP attack that wiped out conventional generating capacity, transformers, and/or SCADA equipment. As related in the article, wind turbines – like all other commercial generating facilities (including hydro) – require electricity to start/re-start if, for whatever reason (e.g., fuel interruption. maintenance shut-down, etc.), the turbines stop spinning under normal circumstances (and wind turbines require sustained maintenance power when not generating power). For conventional facilities, re-start is done with a “black-start” generator, typically a small diesel-fueled generator, when normal power is not available.

Do wind farms have black-start capability? Is it hardened? Are the wind turbines and their control electronics hardened. Are they routinely tested? Will the black-start power kick in soon enough such that the turbine maintenance/sustainability power needs are met and the turbines can be re-started and used? If all these foregoing things were indeed there, and if the wind turbines were re-started and generated power, would that power be deliverable to consumers? I doubt it.

re: ” Carrington event or an EMP attack ”

Are you an expert – do you work in power generation or transmission? Short of that, why don’t you JUST go ahead and also endorse the “precautionary principle” and make a pitch for carbon trading as a means to end ‘global warming’.

Jim,

I do not profess to be an expert. My professional experience includes time with an electric power generation utility and with a developer/supplier of transmission and distribution hardware and equipment. However, most of my professional experience has been on both the technical and business sides of telecommunications equipment development, manufacture, and supply, focused primarily on broadband and wireless. I also hold several system and device patents for SCADA applications. I hold a BSEE (the curriculum of which included heavy doses of advanced math, physics, chemistry, probability, and statistics), and I hold a masters degree in a curriculum heavy in probability, statistics, business-case development, computer-based modeling, and risk assessment.

I do not invoke the precautionary principle since its use is usually (and I would say “uselessly”) limited to those situations where extensive scientific knowledge is scarce and/or unreliable, but for which the effects are believed could be catastrophic. Whereas, much is known about CMEs (Corona Mass Ejections), which are the solar phenomena that cause Carrington Events, and about EMP – and those events occur with little warning, the effects can be catastrophic, and the catastrophic effects are immediate and long lasting. Climate change, which is the phenomenon to which the precautionary principle is almost exclusively applied, might produce effects that are catastrophic, but those effects occur so slowly (decades to millennia) as to allow some mitigation. And very little is directly known about climate change. All that is known is from mostly indirect sources (e.g., old paintings, old newspapers and diaries, ice cores, tree rings, etc., plus a 150-year record of temperature measurements made with varying types of equipment, varying reliability of calibration, varying consistency of reading and recording, and varying siting and maintenance. (I do not include the models because results of models are not data, much less proof, and depend on reliable input data.)

CMEs have occurred (and been directly observed and measured), and continue to occur (the most recent one this past May); but, since the original Carrington Event, none has been directed at the Earth and/or all have been too weak to cause widespread damage (as did the original). US nuclear weapons testing and that of other nations has revealed the nature and effects of EMP such that weapons have been designed to magnify the effects, and there are today at least 2 nations who routinely brag about, and threaten to use, nuclear weapons. So, I’d judge the risk and the effects of a CME or EMP as high enough to seriously consider – as has the US government, many utilities, and many private businesses.

As for “carbon” trading, it is the climate-change equivalent of getting and trading Papal indulgences, which will have as much effect on slowing climate change as indulgences had on reducing sinful behavior.

I’ll end by adding that my original comment was intended to suggest that, as bad as the numbers are for building and operating wind turbines/farms on an ongoing basis, those turbines/farms are also very unlikely be useful/usable when the conventional base-load facilities have been rendered unusable for months-to-years (if ever again) – whereas some have suggested that wind turbines might be useful in those circumstances.

Regards,

Nik

PS – Regarding your related comments to Zigmaster, we live in close-in ’burbs and have an automatic standby generator that can power the entire house, running off of natural gas, piped in by the local utility (who buys from several sources). This generator can be quickly switched over to run on tanked propane if needed. We once had a manual gasoline-powered generator, but hauling in gasoline got to be a pain, and storage for enough to run just a few days was problematic (we have ice storms, tornadoes, hurricanes, overhead power distribution, and many trees).

In a catastrophic event, hauling in fuel (assuming we had fuel and a running vehicle, the needed fuel was available for sale, and that pumps worked) could have been dangerous (theft), as well as arduous, and having fuel delivered would have been spotty. Gas utilities are among those who say they are prepared for CMEs and EMP, and the delivery is direct and underground. It costs us ~ \$35 to run the gas generator for 24 hours with AC running (cheaper than the cheapest motel, assuming you could get to one and get a room).

re: “I do not profess to be an expert. My professional experience includes time with an electric power generation utility and with a developer/supplier of transmission and distribution hardware and equipment. ”

I would recommend you review what current ‘practice’ is by the operators of these systems, such as for magnetic storms; the way you portray the system operators is one of “sitting ducks” waiting for the dominoes to fall, blissfully unaware of ‘happenings’ in our solar system (when such isn’t the case at all.)

PJM Operating Plans in Place

PJM’s operating plans for dealing with GMDs are detailed in section 3.7 of Manual 13. The plan calls for PJM to notify generation and transmission members via the PJM All-Call system and Emergency Procedure posting application when the National Oceanic and Atmospheric Administration (NOAA) issues an alert for a potential GMD with a ranking of 5 or greater on the 9-point “K-index.”

Once a GMD has been confirmed, PJM dispatchers must operate the system under GMD transfer limits determined from studies that modeled several scenarios, including: loss of the Hydro-Quebec Phase 2 DC line to Sandy Pond; tripping of certain extra high voltage capacitors, and reduction or loss of generation at Artificial Island, the site of the Salem and Hope Creek nuclear plants in New Jersey.

The capacity factor is probably closer to 30%. If you’re making a point, give them credit to avoid criticism. You didn’t need to use 19%. Since there are studies, link to one that says 19%.

“Potential taxable income can be written off against the investment for many years…”

Same as with an oil rig, pipeline or coal plant. Same as with a farmer’s tractor. A wind turbine is depreciated over 6 years and can be accelerated. Pick your favorite industry. They are taking write offs. It’s communism right in the good old United States of America.

You can’t be serious. Really, are you that naïve (or that duplicitous)?

German electricity costs are among the highest on the planet. And Germany has had the most “woke” Renewable Energy Law anywhere for nearly two decades. Its primary purpose has been to subsidize solar, then wind power installations (and, of course, the “grid upgrades” which are required to deal with massive fluctuations in electricity supply over very short time periods. That dog’s breakfast of legislation now costs the German economy north of 25 Billion (yes, Billion) Euros per year. And for what, bragging rights? Is there even a prayer of a detectable climate effect, say, in 100 years?

Yet wind power providers are still paid the negotiated feed in tariffs when the wind is blowing, even if nobody wants or needs the electricity at that time. Wind and Solar power always have primacy over other forms of electricity generation.

July 21, 2019 5:11 am

Those other mostly fossil, generators have to be run 100% of the time for peaking, filling in and balancing.
Wind could not be fed into the grid without them
The other generators have to operate at part load, vary their outputs up and down and make more frequent starts and stops, all of which to greater Btu/kWh and more CO2/kWh, i.e, less fuel saved and less CO2 reduced.
In fact, at 17% wind in Ireland, the CO2 reduced was only 56% of what was claimed.
The only reason it became irrefutable, was the gas imports did not decrease as much as predicted.
A government investigation followed and a number of prior studies of grid operating conditions were proved right; they had previously been denied, etc., by pro-wind no-nothings.

Dave,
Ireland increased the capacity of connections to the UK and France grids
Brussels gave Ireland a money grant, i.e., freebie, to make wind look good in Ireland.
That spreads the Irish wind variability and intermittency to much larger grids to be dealt with by THEIR generators.
A smearing of a thin layer of troublesome stuff over a large area, so it would be hardly noticeable.
That only works until other countries ramp up THEIR wind.
In the meantime a pack of carefully constructed lies continues.

“A wind turbine is depreciated over 6 years and can be accelerated. Pick your favorite industry. They are taking write offs. It’s communism right in the good old United States of America.”

Humm. Current the government taxes business based on PROFIT, which simplistically is income minus costs. Building things costs money and so is included in the cost part of the calculation. But instead of including the full cost at the time the bill is paid for the built stuff, the computation of annual cost for the purposes of taxing PROFIT is to take the billed cost divided by the defined (by tax law, not how long it lasts) life. That’s depreciation.

All we have to do to fix this “write-off” problem, if it’s a problem and is in need of fixing, is to simply change the tax law. Governments have the power and responsibility to do that. No need to demonize the businesses who are following the law.

According to the Energy Information Administration Utah’s two largest wind generation facilities sell power to California. I guess that makes it profitable since Utah rates are only about \$0.09/kwh.

“Wind energy produced almost one-fifth of Utah’s net renewable electricity generation in 2017. Utah has five wind farms operating with nearly 400 megawatts of generating capacity from about 200 turbines. The state’s two largest wind farms send power to California. There is commercial wind power potential in the Wasatch and Uinta mountain ranges in Utah’s north-central region and on the mesas in western Utah. However, the state requirement that investments in renewable generation projects be cost-effective has resulted in Utah utilities investing in wind projects in neighboring states, where Utah regulators have deemed the projects to be more cost-effective than proposed in-state facilities.”

MR166
July 21, 2019 6:08 am

The renewable industry hides it’s operating costs and profits very well. New projects are claiming to be able to sell power to the grid at 2 cents/kwh and are using this figure to fool the general public into approving renewables. This is an outright fraud and all of the people connected to this fraud including academia should be held accountable.

It should be mandatory that backup costs also be included in published figures.

The electric power the windmills generate is at best a nuisance on the distribution grid. If you don’t limit the amount of electricity you derive from non-despatchable sources you destabilize your grid. South Australia has more installed wind generation than almost anywhere and 28 September 2016 it all turned off suddenly in high wind conditions and the grid went down. It took days to get the power back on. Now they operate with strict limitations about how much non-despatchable generation can come online. You can’t manage the variability without spinning reserve either. So, like the napkin reads, you have to maintain at least 80% of your dispatchable generation all the time, no matter what, and 100% when the wind stops blowing or the sun stops shining.

The functional use of wind generation on the grid is totally undependable. It is a nuisance, not an asset: Worse than a total waste of money.

Using that term says “I am nothing but a fool that falls for stupid propaganda, no matter how smartly I appear to write.” It’s equal to calling civilian casualties “collateral damage”.

July 21, 2019 7:29 am

The maintenance supervisor of the farm says, “produces an average of 1.3 megawatts/hr (= 1,300 kW/hr)” and subsequently the author of the article discounts this a second time by 18 to 19 %.

The capacity factor per the supervisor is 56%, and the additional deduction of 18-19% puts the capacity factor at about 10%

Better get a new envelope.

Larry Brown
July 21, 2019 3:02 pm

Donald – the capacity factor is 1.3/2.3 = 57% is the effective efficiency of the turbine – i.e., a machine cannot produce at 100% efficiency. The 18-19% is the % of the time the wind blows within the operable range of the wind machine.

July 22, 2019 9:48 am

No Larry, you are double counting. The turbine will reach rated nameplate capacity when the wind is blowing at the higher limit of it’s operating range. The maintenance supervisor was quoting you numbers that included your 20% figure of no-wind/too-fast-wind.

Larry Brown
July 22, 2019 12:23 pm

Donald – ok, thank you for that – that shoots a huge hole in my calculation. The net per turbine income would then go up to about \$265,000 / year – which is indeed about enough to pay for the interest on a 5% loan for the \$4.8 million tower – only.

Part of the problem is that those selling “Renewables” keep bragging about the fact that the electricity is being sold to utilities, under long term contracts. for numbers in the 3 to 5 cents per KWH – “Less than Coal or Nuclear!” As a retired engineer from an electricity utility I can say without hesitation that the reason they sell it for such a low price is that the utilities do not want the headaches of dealing with it. Who would pay full price for a loaf of bread or gallon of milk that was past the sell by date? Why would any utility pay full price for a product that is only available 30% of any hour when the FERC requires that you have 10% spinning reserves for the peak load of the day? The only way that requirement can be met is to have another power plant on line, not producing any power and wasting fuel and costing 75% of the 100% power operating costs. That means they will not pay the renewable’s the actual cost of the electricity, but they need it to meet the states renewable energy requirements or to appease the environmental virtue signalers.

Present thinking here to reduce energy costs here in Texas involves several strategies –

1) Move to an electric (wholesale price) retailer called “Griddy”. Their claim to fame is direct-to-consumer cost of electricity (from the present market cost) for a fixed low monthly administration/service charge (like 10 USD).

2) Implement grid-tie solar with from 4 to 6 ~ 300 Watt solar panels. This will serve to reduce my local demand from the grid during high-peak usage times during daylight hours (esp. air conditioning). I will do my own install bypassing the cost of an installer.

3) Since Griddy is going to cost me more during periods where electric demand is high (AND the cost of electricity on the open market HERE in Texas is high) implement a cheap gasoline or diesel genset capable of starting (an important checkbox) and running an 8,000 BTU air conditioning during those times to save me from being “dinged” by high (spot) market prices the few weeks of the year this is likely. The genset also provides service during blackouts (of which we can see 2 or 3 outages a year for 1 to 3 hours each.) There is a chance for longer outages, again, the genset will meet requirements to operate the A/C and other vital services (like, a computer, DSL router etc.)

I’m looking at ~ 18c per kWh at present, as rates in Texas have slowly risen, in part for charges by the electric delivery company (Oncor) who is defraying HV transmission equipment/lines from west Texas for utilization of wind farm -er- plant electricity production.

Greg

Do you have to have a separate subscription and metering for the grid feed, or does it just reduce what you pull out of the grid?

In France you have to pay a second subscription charge, which makes it all a lot less profitable.

July 21, 2019 12:08 pm

If by “subscription” you mean a 2nd set of wires connecting you to the “grid” the answer is no, you only need one set of wires with a grid tie inverter. The grid tie inverter will reduce your local consumption (pull) off of the grid, and in the case your local consumption is lower than your local production, it will feed the power into the grid over the same wires you use to consume. They can install a “net” meter, which measures two distinct items, namely the power you consume, and the power your produce. Simply put the net meter measures the transfer of energy bi-directionally. As a result, I am given two line items on my bill, production and consumption as determined by the meter readings.

July 21, 2019 4:48 pm

Greg, it is per Donald L’s response below; relatively simple device reduces amount of ‘power’ drawn from the mains while still using the mains for motor starting and other heavy electricity consumers.

Our smart meters are able to ‘work’ with net metering, but one has to agree beforehand with the utility to be paid for this sort of thing. I simply look to offset some of my consumption, for radio and connected computer gear as well as A/C (cooling) during the summer, and heating during the winter.

You are evidence of the decentralization of power production. When the central provider becomes too expensive or too unreliable, or both, people will invest in their own power source.

Hence, it just discredits our case by enabling the alarmists to say we don’t know what we are talking about.

It should be removed.

Yes, and he does not even name the wind farm in question so someone can get the correct figures and check his work.

I know our host does not like just removing stuff but this should not have been published and needs an update saying that it contains serious errors.

Wrong, there are no serious errors, just nit picking. If you had serious objections you would have led with those.

Failing to state sources is a big blunder in science; and a favourite tactic of con artists, like self proclaimed “climate scientists”.

The next biggest blunder is that he fails to realise that the “1.3 megawatts/hr” (presumably 1.3 MW) already takes into account that the wind turbines do not operate 24/7/365 and so uses 18-19% of that. This get a capacity factor of just 11%, which is implausibly low.

His inability to get the units correct makes the numbers themselves suspect. Did he actually mean MWh/day? Is he consistently using megawatts/hr when it should be MW or does he use it for other units as well?

Trying to do a cost analysis when you do not even the know what the physical properties measured are is a joke. Pointing out that someone has no understanding of the subject and has not even done basic research before concluding the profitability of a venture is not knit picking.

I would be equally scathing of someone writing about climate or anything else who clearly had not idea of the subject.

After doing the back-of-envelope review of the economics of these massive wind-farms, let’s turn that sharp pencil to the even more absurd proposal to put these turbines offshore. You still have the same issues of the basic costs of the mechanical bits, but now you are adding installation and maintenance costs that are likely orders of magnitude higher.

Besides that, the geoengineering and “Carbon” sequestration proposals need the exposure provided by a “Sharp Pencil”

“From the article:
“The theory says man’s 3% contribution to the 0.013% increase is causing global warming. How could only 3% of that minuscule 0.013% (i.e., a component comprising 0.00039% of the atmosphere) cause global warming? It can’t.”

The theory actually says that man’s 3% contribution is per year, need that it persists, so over time it builds up.

Yes, I have no idea what he is talking about there, and I suspect neither does he.

There are serious questions about the viability of wind power but this mixed up article is not making them in a credible way.

Ah it seems there is only one large scale wind farm un Utah:

https://en.wikipedia.org/wiki/Milford_Wind

” including 58 Clipper Liberty 2.5-MW wind turbines ”

Nameplate capacity 306 MW
Capacity factor 22.9% (average 2012-2017)
Annual net output 613 GW·h

Units operational 58 X 2.5 MW (Clipper)
107 X 1.5 MW (GE)

So the 58 units discussed seem to be one phase of the installation, comprising about half the 306MW boilplate capacity. So assuming that both models are as good, they produce just over 300GWh per year actual for real electricity, on average.

Taking the author’s 3c/kWh wholesale price: 300×10^6 x \$0.03 = \$9million / year or \$155k/year per tower.

I won’t bother going into his speculative running costs etc.
