Guest essay by Eric Worrall
The Australian Renewables industry has reacted with fury to a leaked suggestion that a new “wind commissioner” will be appointed, to handle complaints about turbine noise.
According to The Guardian;
The Abbott government’s proposed “wind commissioner” represents a “new low in its relentless anti-renewables campaign”, the wind industry says, suggesting the Coalition might do better to appoint a “coal commissioner”.
Guardian Australia revealed on Thursday the Abbott government has agreed to appoint a “windfarm commissioner” to handle complaints about turbine noise, and a new scientific committee to investigate, again, their alleged impacts on human health, in a deal with anti-wind senators to win amendments to renewable energy legislation.
…
“This is a blatant attempt by the Abbott government to use taxpayer cash to appoint a propaganda agent for the anti-wind brigade,” said Andrew Bray, coordinator of the Australian Wind Alliance.
My personal impression is the wind industry might be frightened of the possibility of close scrutiny. Up until now, in my opinion, they have had a free ride – their status as a “green” industry has to some extent allowed them to shrug off worrying reports of adverse health effects from the infrasonic industrial noise pollution produced by wind turbines, and an embarrassing rain of bird carcasses and bats killed by blade strikes.
It looks like, in Australia at least, that free ride is about to come to an end. If there is nothing to reports of adverse health effects and slaughtered birds and bats, the wind industry surely have nothing to fear from a little scrutiny. But if there is any truth to these accusations, it would be better for the wind industry to come clean, to admit the problems and welcome scrutiny, otherwise they may in the future face accusations of having used tobacco industry style dirty tricks, to conceal significant health and environmental problems associated with wind turbines.

I have to say there are other countries starting to cautiously reconsider the CAGW response.
Even if you felt a responsibility as a politician to cover a possible risk from CO2 emissions, and there is room for the CO2 emissions to be an issue, no sane person would any longer see wind farms as a solution to that potential issue.
New project optimism could be an excuse for early subsidies but once the realities are in you have a moral duty to say stop.
I think I saw a number of something like a very significant portion of a trillion dollars has been pushed at the issue via wind farms, the jury is in and scale has not fixed the cost hurdle nor has it improved the CO2 emission issue should it be an issue.
there is much talk internationally about the poor in rich countries, low productivity growth, and the lack of traction in solving these issues. could it be the diversion of massive quantities of investment capital into projects that increase the cost of energy to the all but affecting the poor more significantly.
Putin and the Chinese and others must consider their investments in antifracing and talk about supporting the CAGW initiatives as money well spent.
No one’s yet mentioned, or I missed the mention, another problem, power density. Another is that infrasound doesn’t just damage humans, but the whole biosphere, animals and plants, and it may be easy to show that.
Then yet another: A windfarm permanently changes the weather, even climate downstream. We are all down stream. We are all damaged. The wind, the water, and the sun are the planet’s natural climate regulating mechanisms, and if we ever draw significant energy from them, it will be net detrimental.
Wind brings dust off the Boedele Depression in Africa, and fertilizes the Amazon Basin with it. Were there wind farms in the gap to the east of the depression, the Amazon Rain Forest would die a slow agonizing death.
I exaggerate, but not much.
===============
Wind power is an abomination that destabilizes the electrical grid and drives up energy costs through huge operating subsidies that are passed on to consumers through their bloated electrical bills.
I suggest that in each region where wind power had been implemented, a coalition of taxpayers groups and organizations representing families, the elderly and the poor should launch vigorous campaigns to end ALL operating subsidies to wind (and solar) power schemes.
We need a catchy name: I suggest our movement should be called BREAKING WIND.
Well what are you all waiting for?
Let’s get out there and …
There are ,and have been, orginisations out there, “save our sound” in mass . helped to stop “cape wind”. New hampshire wind watch is fighting wind projects on NH mountain ranges, These are non profits. Check your area and put your money where your is.
“ILL WIND”, ?
A quick trip along highway 10 about 2 hours out of LA and you can see what happens when the subsidies stop and wind power needs maintenance.
i wonder if these wind energy folk have reinstatement funds set aside.
in my mind this is where the attack should come from, make them set aside funds to reinstate the environment. After all they are environmentally conscious folk.
“set aside funds”? They get huge subsidies just to build up that crap. Where do you think the money for the funds would come from?

OK, fair is fair.
There should not be a “Wind Commissioner”
There should be a “Noise Commissioner” with special portfolio for “Man-made Turbulence”.
If it is wind turbine noise, gas turbine compressor noise, or Highway-Railway Noilse — its noise that affects health and wellbeing. Some noise can be mitigated. Some noise can’t and should attract the attention of the Noise
CommissarCommissioner.What’s the noise before the windfarm?
What’s the noise after the windfarm?
If the Windfarm is within half a mile of an interstate highway, there is probably no harm, no foul.
But if a windfarm is built in a rural area and the noise affects nearby residents, there ought to be some measure of compensation.
If a wind turbine is erected in a forest and someone IS there the hear it, then it DOES make a sound. Pay up.
As with most things in the media, the Guardian’s report is at best incomplete, and the result may be even less to the liking of the wind industry.
The proposed changes are actually being driven by the Senate Select Committee on Wind Turbines, which has been hearing appalling reports of the impact of wind farms on people in Australia, including some who are hosts for wind turbines. The Committee has produced an interim report with a series of strong recommendations
It is available at
http://www.aph.gov.au/Parliamentary_Business/Committees/Senate/Wind_Turbines/Wind_Turbines/~/media/Committees/wind_ctte/Interim_Report/report.pdf
In summary, it has recommended:
* the Commonwealth create national wind farm guidelines (see more details below), to be finalised within 12 months, to be incorporated by state governments
* including a national standard on infrasound and low frequency noise and its measurement,
* with the latter based on research findings to be developed by an Independent Expert Scientific Committee (IESC) on Industrial Sound, which will also provide advice about the sound impact of prospective and existing wind farms
* requiring transparency of data about the operation and noise emission from individual wind farms
* plus the establishment by the Commonwealth of a National Wind Farm Ombudsman as a single point of complaint for people suffering from wind farms
* with eligibility of wind farms to received RECs to depend on compliance with the national guidelines and particularly the noise measures
* and this to be paid for by a levy on wind farms (as a condition for being eligible to issue RECs)
The stick that drives all this is the dependence of wind farms on being able to issue, and get paid for, Renewable Energy Certificates (RECs). Without RECs they are not financially viable. RECs are authorised under Commonwealth legislation and the Senate Committee has recommended that legislation be amended to enforce the other recommendations.
The Committee has recommended that the national wind farm guidelines must set minimum standards (which all jurisdictions must observe) on the following issues:
* ongoing wind farm operator compliance with planning conditions and requirements for holding records;
* requirements that wind farm operators publicly disclose certain operating data;
* buffer distances between turbines and residences;
* specific requirements for community and stakeholder consultation at each stage of planning, development and operation;
* visual and landscape impacts;
* the impact on birds and bats;
* indigenous heritage issues;
* aircraft safety; and
* the property rights of neighbours.
The committee has a strong representation of cross-bench (not government, Labor or Greens) Senators and they appear to be driving the recommendations made. The Government is after cross-bench support for aspects of the RET revisions it wants to enact, so the cross-benchers are in a good position to get adoption of the Committee’s recommendations, to which Abbott is probably not averse in any case.

Not a fan of wind turbines mainly for their variability, but as far as health effects of infrasound from them, I’ll believe in their claims the moment you can produce anyone getting paid rent for them on their land that suffers from infrasound.
Now for the the good news for wind fans as Australia reaches peak wind power generation at 3200MW explained here-
http://www.wattclarity.com.au/2015/05/aggregate-wind-farm-output-tops-3200mw-in-the-middle-of-the-night/
Wow, closing down the coal industry is nearly at hand Green folks until you look more closely at the output of only around 1300MW just over one and a half days earlier in that second graph and those negative prices impacting fossil fuel returns which have to cover that 1900MW of variation-
http://www.wattclarity.com.au/wordpress/wp-content/uploads/2015/05/20150510at1400nemwatchscreenshot.jpg
but that aint the be all and end all Green wet dreamers-
http://www.wattclarity.com.au/2015/03/approaching-62-hours-becalmed-on-the-mainland-what-would-this-mean-for-battery-storage/
Facts! We don’t need no lousy facts from skeptics in the pay of big fossil.
I live about 2 km downwind of the nearest turbines in the Tehachapi wind farms. I have no financial interest in them except as affects my house value. During the past several years, on only two occasions, I have heard a very low frequency rumble while sitting inside my house. They lasted an hour or so, and I attribute that fact to the wind speed and direction being just right to get several turbines acoustically ‘talking’ to each other. I also note that the newest, biggest turbines are laid in arcs, rather than straight lines.
62 hours is nothing, we’ve had three week intervals of insignificant output in the (supposedly windy) UK.
observa said …………I’ll believe in their claims the moment you can produce anyone getting paid rent for them on their land that suffers from infrasound…….
Here you go, hot off the press………..http://stopthesethings.com/2015/06/15/sa-farmers-paid-1-million-to-host-19-turbines-tell-senate-they-would-never-do-it-again-due-to-unbearable-sleep-destroying-noise/
One State Government has successfully got rid of it’s car manufacturing industry, two coal power stations, support industry and built the biggest proportion of wind gene3ration in the country. Unemployment has sky rocketed. The young are starting to leave and move interstate for work. Unemployment is at record levels. Green policies are working well. South Australia is the second state to go really green and go bankrupt at the same time.
Do not look at Australia as being a wonderful haven. There is a real crisis developing in Australia from green policies
Australias experience with wind farms is no doubt around the same as every where around the world.
Unreliable, intermittant and with huge subsidises totally worthless for a modern economy. Then there is the down sides.
People,let’s get this straight,wind farms are purely and simply a con job.No more no less.
Two technicians got caught on top of one of those giant windmills after it started on fire.
There are pictures on the Internet of them embracing on top as they knew they were not going to make it. One jumped. The other tried to go back through the housing which was on fire but didn’t make it.
My thoughts are with their families, friends and colleagues.
Two horrible ways to go.
Whilst probably pretty rare as a technician-killing event, are there moves to it evacuation devices – at sea, we have ‘lifeboats’ and ‘life-rafts’.
Could the bird choppers be fitted with external life-lines, which could be clipped on to and allow a controllable rate of descent – after the first fifty metres – so getting the techie out of the trouble zone quickly. Would need capital and maintenance, and probably training.
Sort of zip-wires?
Or parachutes?
Or a helter-skelter on the outside . . . .
Or are the techies’ lives of no worth compared to saving the planet [except when we need fossil-fuel [or pumped hydro] back-up]?
Might I be feeling just the tiniest atto-smidgen cynical?
Auto
Or Nuke back-up [NB – bird shredders are m u c h better at base load than Nukes. I am told].
Auto – pointing out to mods that this really, t r u l y , doesn’t need a /sarc tag for anyone one nano-smidgen brighter than a medium sized cactus.
Parachutes are quite heavy items to wear, and the ripcord type would be a bit marginal in terms of time to deploy and decelerate the wearer, from that height, A static line type would open quicker, but would require the line fixing somewhere before jumping.. Probably a simple abseil system would be adequate in light winds, provided the top line section near the burning nacelle was fireproof.
The Capacity Factor of wind power is typically a bit over 20%, but that is NOT the relevant factor.
The real truth is told by the Substitution Factor, which is as low as 4% in Germany – that is the amount of conventional generation that can be permanently retired when wind power is installed it the grid.
http://www.wind-watch.org/documents/wp-content/uploads/eonwindreport2005.pdf
(apparently no longer available from E.ON Netz website).
Re E.ON Netz Wind Report 2005 – see especially:
Figure 6 says Wind Power does not work (need for ~100% spinning backup);
and Figure 7 says it just gets worse and worse the more Wind Power you add to the grid (see Substitution Factor).
Same story for grid-connected Solar Power (both in the absence of a “Super-Battery”).
This was all obvious to us – we published similar conclusions in 2002.
Two trillion wasted dollars later, the rest of the world is waking up.
Wind power – it doesn’t just blow – it sucks!
Sorry, but I have to disagree with your comment on grid-connected solar power. This is my opinion, but supported by a recent conversation with a Southern Cal Edison lineman. His territory includes both wind farms and multi-megawatt solar plants. If you look at a utility power load curve, in the summer here in the southwest US, peak power is about 2X the base load. Solar power is generated when the load is greatest, so it is a substitute for the peaker plants that run at higher cost than base load plants. Until you reach ~30% of the grid load, PV does load leveling. Now I didn’t say anything about cost or subsidies…….
Do you know how much the subsidy is for solar power in your area? I do not.
But in other locations is it 12 times the price of conventional power.
In my location, wind power is subsidized at 4 times (20 cents per KWh) the price of conventional power (which costs 5 cents per KWh all-in) , and that wind subsidy is paid 24/7, even when the wind power is not needed and must be shed from the grid.
If any of the claims that wind or solar power are truly competitive with conventional power generation are true, then end the subsidies to wind and solar today. I predict they will go broke tomorrow.
Alan… Solar heating has been truly competitive with conventional heating ever since they began installing glass windows on the south side of buildings in cold climates.
Joel – is solar heating grid-connected? No it is not.
Solar hot water heating also works I some areas. It is not grid-connected wither.
Correction :
Solar hot water heating also works in some areas. It is not grid-connected either.
New onshore wind is cost-competitive with new advanced cycle gas
Wind power’s LCOE (leveiized cost of electricity) for new build is comparable to that for the most efficient gas generation according to the most recent USA EIA figures:
Average onshore wind 73.6 vs 72.6 advanced combined cycle gas ($/MWh)
See http://www.eia.gov/forecasts/aeo/electricity_generation.cfm
This is an average. The EIA gives the ranges as follows :-
65.6 – 81.6 $/MWh Wind
68.6 – 81.7 $/MWh Advanced Gas Combined Cycle
So according to the EIA the best power from wind can beat the best power from gas.
Further, the variable cost element of this gas generation is 53.6 $/MWh of which most is fuel. If you looks at the most recent Lazard’s figures (version 8), this is more than the cheapest unsubsized wind power (range 37 – 82 $/MWh). The lowest costs will be in the US interior states. See Lazards V8 – http://www.lazard.com/PDF/Levelized%20Cost%20of%20Energy%20-%20Version%208.0.pdf.
If you are an interior US state using 100% advanced CC gas generation, you would expect to provide cheaper power and make more profit by installing onshore wind turbines as well, because the LCOE for the wind would be lower than the EIA-provided variable costs, mostly fuel costs. When the wind blows you make money by saving on fuel costs. When there is no wind you run the gas generation at the old cost. You would expect to use wind power around 40% of the time (rising to 60% with the next-but-one generation of wind turbines), and gas generation the rest of the time.
These conclusions are based on 2020 pricing which is what you would be looking at if you are starting to plan new generation right now.
ristvan said :
You would only be able to get figures like this by using old wind generation technology and prices, and maybe by comparing with a period when the gas prices were so low that no gas producer could make a profit, which is why they went up afterwards. LCOE would include full capital costs, so should always be comparing new with new.
Rud’s statement is cherry picking figures to misrepresent the true position, rather than providing current information to help us understand what decision should be taken when planning new generation.
In summary, new wind generation is highly competitive with gas generation if you use the most recent figures.
“In summary, new wind generation is highly competitive with gas generation if you use the most recent figures.”
Is that right?
So why do the Wind gang scream like stuck pigs about driving out investment and all sorts of other horrors if they are prevented from mugging the energy users for subsidies?
You’re still totally ignoring the inconvenient fact that every milliwatt of unreliable, unpredictable wind power has to be supported by the same amount of conventional thermal generation for the half to three quarters of the time it is not generating, with the concomitant extra wear and tear on the thermal plant, leading to the inescapable conclusion that the nasty bird and bat mincers are nothing but a complete waste of time and money, and cannot by any stretch of imagination be described as environmentally sound.
if you care about birds and bats you are not answering the right question. The appropriate question is :
Here is a chart which may assist.
http://assets2.motherboard.tv/content-images/contentimage/no-slug/d75936b917b5dbe2376ac949a9a0acf9.jpg
Climate Pete: “if you care about birds and bats you are not answering the right question.”
Ah, but unlike wind, all those others are reliable 24/7 sources of dispatchable electricity, so the deaths due to wind turbines are entirely unnecessary.
In any case, you’re wriggling, as the mortality rate was not my primary point – which I notice you entirely failed to address.
Further, you didn’t supply any mortality figures for hydro, such as the Banqiao dam, for example:
The dam failures killed an estimated 171,000 people; 11 million people lost their homes. It also caused the sudden loss of 18 GW of power, the power output equivalent of roughly 9 very large modern coal-fired thermal power stations.
https://en.wikipedia.org/wiki/Banqiao_Dam
Here’s another:
The devastating earthquake in Sichuan, which took at least 69,000 lives in May 2008, may have been unleashed by the huge Zipingpu Dam. New scientific evidence suggests that the filling of the Zipingpu reservoir may have activated a dormant fault line near the dam site. This is all the more worrisome because the Chinese government plans to shift the center of its dam-building efforts into seismically active regions.
http://www.internationalrivers.org/blogs/227/china-earthquake-a-dam-induced-disaster
I call total BS on most or all of your claims Pete.
Sources?
Here’s an EIA chart showing levelized calculated costs of various forms of electricity production:
http://www.eia.gov/todayinenergy/detail.cfm?id=21492 The fine print below the chart says it includes subsidies for the wind numbers.
Compare that chart to one that uses production numbers from existing plants here, about 10 pages down:
http://www.world-nuclear.org/info/Economic-Aspects/Economics-of-Nuclear-Power/
In my link – http://www.eia.gov/forecasts/aeo/electricity_generation.cfm – there is a note on subsidies. The note indicates that the subsidies only apply to those items with figures in the three subsidy columns. So wind prices in table 1 and table 2 appear to be unsubsidized prices.
The EIA link you provide seems to be at odds with my link as far as whether subsidies are included or not. Since the EIA appears to be at odds with itself, maybe we should go with Lazards.
On the other link, existing plants are always cheaper than new ones. However, the point about the fuel costs does not depend on when the plant was installed. Older plants tend to be less efficient and therefore fuel costs for older plants tend to be higher.
If your cost comparison is correct, I must ask the question — Why is wind highly subsidized in Texas and nearly 100% of the Western world? In Texas I pay for it every month on my electricity bill over and above my usage and taxes?
If wind is intermittent (lack of wind, too cold) and requires back up power from inefficiently spinning natural gas plants, how is the cost of this back up power considered in you calculations of wind costs?
West Texas wind does not blow in what time of year? Summer! The exact time when demand is highest! Conventional power plants are the only way to meet demand not being produced by wind. The last time I drove through west Texas was in late October. Less than 50% of the windmills were even turning.
Sorry, but I am not buying your assertion that wind is competitive with a natural gas plant when ALL costs are considered.
Subsidies and costs
In the past wind has been heavily subsidized. This was to get up to critical manufacturing mass for a new (and therefore expensive) technology. As the technology matures, efficiency improves and costs come down then the subsidies for new renewables generation builds should be corresponding reduced.
In other words the subsidies for new wind in Texas should be set to be less than for old wind, and the money you are paying is
The problem has been that there hasn’t always been a path of slowly reducing subsidies for wind. It has been single level stop go.
So, a question for you. Do you have a breakdown anywhere as to what proportion of the wind subsidy on your bill relates to which year, because that ought to demonstrate the reducing price of wind power over time. The subsidies for installations in a given year would be compared with the new wind power installed that year.
If wind is cheaper the fossil fuel running costs (as it is in the USA interior and will be elsewhere soon), then the baseline cost is always fossil fuel generation, and wind represents a cost saving on this. The wind power prices are calculated based on the time the wind blows and the turbines are generating, not on 100% of the time.
Texas wind match with air conditioning load
You are absolutely correct that wind is not a good match for Texas summer peak air conditioning load. Solar PV is a better match for this. As soon as solar LCOE (with federal but not state subsidy) is less than fossil fuel generation costs it makes sense to grow this rapidly.
That leaves the summer evening period when the sun is on the horizon or down and PV generation is low.
The wind speed in Texas is highest in northern Texas, so wind generation costs are lowest there. However, there isn’t a good match with evening air conditioning load.
Texas has the possibility of using onshore or offshore wind generation on the coast of the Gulf of Mexico. My understanding is that this has offshore breezes after the sun has risen, and onshore breezes after the sun goes down, caused by increased heating of the land by day compared with the sea. The wind speeds on the Gulf of Mexico are not as high as in the north, so the turbines are likely to be higher and with bigger rotors, but to have smaller generators than you would otherwise expect from the physical dimensions. This is likely to provide a good match to summer evening peak air conditioning load.
And yes, in times when the wind is not blowing or sun shining, fossil fuel generation is a sensible method of generation.
so no need for subsidies
How can you reconcile the different views on wind and solar costs?
How is it possible to reconcile the two conflicting views that wind power is currently the cheapest source of mass power generation, and that it is expensive because it is intermittent? Surely the two are diametrically opposed.
One way to look at it is to assume you start with a pure fossil fuelled generating system, maybe a mixture of gas and coal-fired. So we already have the base generation in place at a defined cost. Then see if adding wind now and solar later can improve on it.
The best wind is cheaper to install for generation 40% of the time than the pure cost of fuel (and the other smaller costs which make up the total variable cost) for the most efficient gas-fired generation plant. See the post above.
This best US wind is located in the US interior states where the land is flat and there are no obstacles. The power output of a wind turbine depends on the cube of the wind speed, so a mere 30% faster wind gives you 120% higher power availability – probably rather more than you were expecting.
In the US interior, if you install a wind capacity up to the gas-generating station capacity (but not much further at this point), then the cost of the wind turbines will be more than covered by the fuel savings.
Solar PV (photovoltaic) is currently a little more expensive than gas and wind generation on average. However, panel prices have dropped 78% in the last 5 years.
Can this huge decline in solar prices continue into the near future?
The estimates are that, for each doubling of solar panels manufactured, the costs decrease by 16%. For four doublings (a factor of 16X in terms of increased manufacturing volume), you would expect a further 50% price drop. That is enough to make solar prices cheaper than wind fuel costs, and probably cheaper than coal generation fuel costs. It does not assume any major technological innovation – purely scale manufacturing.
It is highly likely that solar volumes will keep increasing as required to get to a 16X increase in manufacturing. Modi has stated that India will install 100GW of solar power by 2022, up from 3GW currently. Other nations are expected to increase solar installations too.
So, yes, it looks like the decline in solar prices will continue.
As a rule of thumb, in the best places solar capacity factors will be at 30%, average 20% and in the worst places 10%.
In the 2030 timeframe wind will also reduce in cost, and it is highly likely that it will go below the fuel costs of coal generation.
Go back to the fossil fuel grid. Install the total generation capacity again in both wind and solar (i.e. a total of three times the current capacity). Total costs will be lower because the fuel savings more than pay for the wind and solar generation capital costs.
In the best place you will have a grid that is powered something like 60% by renewables (40% wind + 30% solar only equals something like 60%, not 70%, and 10% of the time you have spare power to use for something suitable), in which power prices are reduced and CO2 emissions will be only 40% of the emissions expected with no renewables.
You would expect to eat into the 40% using CSP – concentrated solar power, in which the sun’s rays are focussed on a target contain molten salt. The hot salt is stored and can be used after the sun goes down to generate power to satisfy an evening peak. The straight financial case for this is more complicated and the assumptions less clear, so let us leave it for now. There are other ways of cutting into the 40% too, but, hey, the picture on this might change significantly by 2030 so why worry about it right now – we are nowhere near the full wind and solar capacity required yet, so let’s do that one first.
So by using fossil fuel + wind + solar there is a good chance that power from the 2030 grid will be cheaper than today, even though you have 3X the generation capacity installed, because of the huge fuel savings. Fossil fuel remains the backup to the gaps in wind and solar generation.
The trick is to think of it, not as wind and solar or fossil fuel, but wind and solar and fossil fuel, and focus on possible fossil fuel cost savings. Then the possibilities and limitations become clearer.
Allan MacRae said
This is a cherrypick of old technology wind turbine capacity factors.
As wind turbines get bigger they get higher too, and the wind speed at 100m above the ground is 30% higher than 10m off the ground, giving 120% higher power output.
But wait, there is even more shocking news to come!
Silent wind power revolution
The trend nowadays is to have larger rotors (power output is proportional to area swept, as you might expect), but smaller generators. These techniques are predicted to achieve capacity factors of 60% from onshore wind using specially designed turbines in specific windy areas.
See http://cleantechnica.com/2015/05/26/new-wind-turbines-capacity-factor-increase-40-60/
and http://cf01.erneuerbareenergien.schluetersche.de/files/smfiledata/4/7/8/6/3/2/114bSWRcaseUSA.pdf
This second reference explains that the new technology can be used to achieve a 60% onshore wind capacity factor in an area of just under 2m square kilometres area of the USA, and 3m square kilometers for a capacity factor of 50%. See page 25 of the second link above.
Clearly the higher capacity factors translates into lower wind generation costs.
In conclusion, the future onshore wind capacity factors are likely to rise significantly. 20% was a valid figure only for the early days of wind. Current new wind install capacity factors are in excess of 30%. Future USA onshore wind installations are more likely to be in the range of 40-60%.
Climate Pete:
Most people want to switch their lights on – not off – when the Sun goes down.
Unless and until large scale energy storage is perfected then solar power will remain an inconvenience and an expensive additional cost to an electricity grid supply system.
Your verbose ‘BS baffles brains’ cannot alter these truths.
Richard
Solar and wind will soon be cheaper than the fuel costs for fossil fuel generation. At that point you use them when available and fossil fuel when not.
Climate Pete:
You demonstrate complete ignorance of the subject when you write this nonsense
Firstly, that is an admission by you that “solar and wind” now cost more than “the fuel costs for fossil fuel generation”.
Secondly, fuel costs are not the only costs of power generation. Indeed, wind and solar have no fuel costs but you admit they now cost more than “the fuel costs for fossil fuel generation”. There is no possibility of wind and solar becoming cheaper than fossil fuel generation in the foreseeable future.
Thirdly, and most importantly, your suggestion that “you use them (i.e. wind and solar) when available and fossil fuel when not” is a suggestion that would increase the costs of power generation, increase (n.b. INCREASE) the fuel consumed by fossil fueled power stations, and increases emission from power generation.
I explain this as follows.
As you would know if you had read and understood my lecture which I linked for you,
Conventional (i.e. thermal) power stations fission a material or burn a fuel to obtain heat that is used to boil water and to superheat the resulting steam which is fed to steam turbines (some power stations – e.g. combined cycle gas turbine: CCGT – also use gas turbines in combination with steam turbines). The turbines drive turbogenerators that make electricity.
A thermal power station takes days to start producing electricity from a cold start. Time is
needed to boil the water, to superheat the steam, to warm all the components of the power station, and to spin the turbogenerators up to operating speed (anybody who has boiled a kettle knows this will not be instant).
Therefore, the thermal power stations do not – and cannot – stop using fossil fuels when wind turbines operate. The power stations need to keep burning their fuel to boil their water, to superheat their steam, to warm all their components, and to spin their turbogenerators at operating speed so they can generate when the wind turbines don’t operate.
Furtheremore, each thermal power station is designed to provide an output of electricity. It can only provide very little more or very little less than this output (i.e. in the jargon a power station has a “low turndown ratio”). And if it provides less electricity – e.g. because the wind changes so a wind farm starts generating – then it uses MORE fuel so creates more emissions. This is because its efficiency reduces when it produces less than optimum electricity output (the effect is like driving a car at 5 mph in fifth gear: it can be done but it uses a lot of fuel).
Climate Pete, I don’t know if you have been misled by wind industry disinformation or if you are employed by the wind industry to spread disinformation. But your post I am here answering demonstrates that one of these is the case.

Climate Pete:
Global electricity production increases by about 450 terawatt hours per year.Thats roughly the equivalent of adding a country the size of Brazil every year.What would it take to keep up with just the growth in global electricity demand?The United States has more wind capacity than any other country,about 60,000 megawatts at the end of 2012.So just to keep up with the electricity demand growth,the world would have to install about four times as much wind energy capacity as the States has right now and would have to do so annually.Dream on my boy.
It gets even sillier when you look at carbon dioxide emissions.According to the American Wind Energy Association 60,000 megawatts of wind energy can reduce carbon dioxide emissions by 80 million tons per year.So to stop the growth in global carbon dioxide emissions of 500 million tons per year,using wind energy alone,requires the installation of about 375,000 megawatts of new wind energy capacity annually.The power density of wind energy is about 1 watt per square metre so a land area of 375,000 square kilometers would need to be covered.Thats an area the size of Germany to be covered in wind turbines every year.You want daily?About a thousand square kilometres per day.
Thats not climate science,Pete,it’s arithmatic.
JB, remember that if you put up turbines on farmland, you can still use the land for farmng. Wind turbines don’t prevent you from tilling the soil underneath them, so the “power density/land use” argument is moot.
Joel,get real mate.We’re talking about thousands of sq kilometres.You can’t get round that area on bikes.What are you proposing,that we beam the farmers and maintence crews in?Maybe we could adapt the turbines to double as housing.I am sure if we painted them nice colours and carpeted the stairs everyone would love to live in one,especially because they were helping save the planet.

Very little offshore wind capacity has been or will be built because it is 4 times more expensive than onshore.To quote one of your high priests,James Hansen,’suggesting that renewables will let us phase rapidly off fossil fuels in the US,China,India or the world as a whole is almost the equivelent of believing in the Easter Bunny and the Tooth Fairy’
So what do you know that he doesn’t?
JB is a little out of date on offshore wind prices. The contract for power from the 400MW Danish Horns rev 3 offshore wind farm has been signed for around $12 / KWh – not the cheapest form of power by far, but certainly not four times fossil fuel generation. More like 50% more expensive, and this for a technology that is far from mature.
Watch out onshore wind!! When UK gets in contract prices at some point for the 2.4 GW first phase wind farm of Dogger Bank (total 7.2 GW), we might see offshore wind prices tumble like there’s no tomorrow.
http://renews.biz/84884/vattenfall-wins-horns-rev-3-tender/
Both Joel and JB have it dead wrong!!!
You can’t be a real macho offshore (and maybe onshore) wind turbine unless you have a proper helicopter landing pad at the top of your nacelle.
Heh, wind was abandoned at maturity, and for good reason.
========
If they’d only had helicopters back when wind was abandoned industrially.
=================
The factor you overlook is straighforward meteorology. High pressure regions can cover vast amounts of land, and during such events, NO turbines in that region produce any useful output. In some cases the whole of Europe has near-nil winds for days on end.
That, and the energy available in sunshine drops by a factor of at least ten in cloudy conditions. So, no matter how efficient your PV panels, clouds reduce their output to less than 10%. You cannot get more out than arrives in. The other problem for load balancing is that solar output can vary extremely quickly in strong wind, part cloud cover condtions, far faster in fact than large turbine output varies.
is there a wind-based solution to reducing the wind generation gap
Ian makes a very good point here. Expanding the grid size in Europe alone only increases wind capacity factors a little. So the straight answer to the question is
Don’t know what you can do about it in the USA. But here in Europe there’s a very good solution to reducing wind power gaps.
You extend the mooted European Supergrid to North Africa. There the wind does not correlate with European wind because it is the trade winds whistling over from the Carribean. When they hit the coast of Africa they turn to go South East. The Trade Winds are caused by tropical convection, so the rise in the tropics with a particular angular momentum caused by the earth’s rotational speed (in km/hour) – which is maximum in the tropics. Then they descend in the sub-tropics, and because the earth’s rotation is less there but angular momentum must be conserved, the wind speeds are generally good and the wind is more constant than Europe.
It is the different physical cause which makes North African wind independent of European wind.
You must factor in something like 1.5 cents per kWh to get North African power into Europe (say London).
It’s obvious, but let’s say it anyway – this does not apply to European and North African solar power because they are at the same longitude and the sun therefore keeps very similar hours!!
In summary there’s no European solution, but there’s an excellent North African solution to the gaps in European wind!!!
Libya would have been a nice place for them but for those meddling Muricans.
==========
Oops, meant the trade winds blowing West to East turn sharp right and end up blowing North East to South West (not to South East). Apologies for this.
Climate Pete:
If wind power were economic and viable then oil tankers would be sailing ships.
Wind power for power generation is
expensive,
polluting,
environmentally damaging,
only provides electricity when the wind is strong enough but not too strong,
and never provides electricity of use to and electricity grid supply,
but provides an additional cost to an electricity grid supply system.
Anybody who wants to understand these realities can read this.
Richard
and now they need no subsidy
Bill Treuren:
You say wind power needs no subsidy. Really?
Please explain why they get both subsidies and mandates which – as the above essay explains – require ‘tame’ politicians to maintain.
Richard
I think he was being ironic. Your question is for Acolyte First Class, Climate Pete.
===========
Richard document is from 2006.
Richard,
Things have changed very considerably since 2003, which is the date of most of the data in your presentation. Wind power is very considerably cheaper than it was. New onshore wind capacity factors are considerably higher than they were in 2003.
Onshore wind power is now :
often cheaper than the most efficient gas generation
much less polluting than fossil fuel generation
much lower level of environmental damage than fossil fuel generation
much lower level of avian deaths than fossil fuel generation
higher capacity factor – expected to be up to 60% for onshore wind in the near future in good locations
“Onshore wind power is now :
often cheaper than the most efficient gas generation”
But we can never get rid of the gas/coal/nuclear generation because the wind is entirely unreliable and unpredictable.
So we’re paying for it twice, meaning that the wind turbines are entirely superfluous.
Further, the sheer area of land necessary to build sufficient turbines to produce as much energy as one average output CCGT plant is massive, and like it or not the intrusiveness of wind turbines is rapidly alienating increasingly large numbers of the electorate.
Plus the environmental effects of the several thousand tons of concrete – a major source of CO2 – and the extraction of the rare earths such as neodymium that is necessary to build compact generators is something you wind enthusiasts never take into account.
The concentration of rare earths in the ore is very low, so they must be separated and purified, using hydro-metallurgical techniques and acid baths. China accounts for 97% of global output of these precious substances, with two-thirds produced in Baotou.
The foul waters of the tailings pond contain all sorts of toxic chemicals, but also radioactive elements such as thorium which, if ingested, cause cancers of the pancreas and lungs, and leukaemia. “Before the factories were built, there were just fields here as far as the eye can see. In the place of this radioactive sludge, there were watermelons, aubergines and tomatoes,” says Li Guirong with a sigh.
http://www.theguardian.com/environment/2012/aug/07/china-rare-earth-village-pollution
1) ” the wind is entirely unreliable and unpredictable.”
..
No, three day and five day weather forecasts are pretty accurate as far as predicting wind speed and direction. This allows utilities that use wind as a source to schedule loads.
..
2) ” rare earths such as neodymium that is necessary to build compact generators”
..
Large wind turbines in utility scale wind farms are not of a direct drive design. They do not use permanent magnets made with neodymium. Their magnetic fields are produced electrically.

” the intrusiveness of wind turbines is rapidly alienating increasingly large numbers of the electorate.”

That’s funny. The cattle grazing under the turbines in Texas don’t seem to mind them at all. The ranchers who lease their land to the wind farms also like the additional rent checks that arrive monthly.

Climate Pete:
You assert to me
The Laws of Physics have NOT changed since 2003.
The explanations I proved in this lecture each and all remain true.
All energy is “free”: it was all created at the Big Bang and now cannot be created or destroyed. But it is expensive to collect energy and to concentrate it so it can do useful work.
Fortunately, nature has done much of the collection and concentration for us.
The energy concentrated in ancient stars is available in radioactive materials, notably uranium. Energy from formation of the solar system (including collected radioactivity) is available as geothermal energy. Solar energy collected by photosynthesis over geological ages is available as fossil fuels. Solar energy collected by evapouration of water over large areas is available as hydropower.
Diffuse energy sources were used for millennia because higher energy densities were not available. These diffuse sources included wind power, solar power, biomass and power of the muscles of slaves and animals.
These diffuse sources were abandoned when the greater energy intensity in fossil fuels became available to do work by use of the steam engine. But, of course, hydropower was not abandoned because it has high energy intensity.
There is no possibility that an industrialised civilisation can operate if it abandons the sources of high energy density collected by nature and returns to using the energy that humans collect themselves by e.g. using wind turbines and solar panels.
Add to that the fact that wind and solar are intermittent so real power stations must operate all the time to ensure there is power when e.g. there is no wind at night and it is unavoidable that wind power and solar power are not needed and are expensive additional costs for power generation.
As I said,
If wind power were economic and viable then oil tankers would be sailing ships
And
Most people want to switch their lights on – not off – when the Sun goes down.
Richard
Four percent. A windmill can replace four percent of its rated capacity in reliable back-up power. Climate Pete, they been foolin’ you again.
===============
How could Richard possibly get the wind physics right but the conclusion wrong?
To summarise the physics in Richard’s document, wind power is proportional to the area swept (square of the rotor radius or diameter) and to the cube of the wind speed.
http://scienceandpublicpolicy.org/images/stories/papers/reprint/courtney_2006_lecture.pdf
The big factor Richard omits is that wind speed increases by height :
I can find no mention whatsoever of this fact in Richard’s document above, and it is crucial, as the maths below shows.
http://www.mpoweruk.com/images/speed_height.gif
At 110m off the ground the wind speed is 1.4 times the wind speed at 10m off the ground.
Cube this and at 110m off the ground the available power is 2.7 times the power 10m off the ground.
At the time Richard’s document was written the largest radius rotor he documents was 22m, and hub heights were considerably lower than at present. Today there are turbines installed with rotors of 80m radius (160m diameter) and 100m (200m diameter) is on the drawing board.
This has significant impacts. For instance all the Danish capacity factors in his document were around 20%.
The average capacity factor for new Danish offshore wind farms in 2014 was over 40%.
New “silent wind power revolution” technology wind turbines (next generation but one) are expected to achieve 60% capacity factors in 2m square km of the best USA wind areas.
See http://cleantechnica.com/2015/05/26/new-wind-turbines-capacity-factor-increase-40-60/
and http://cf01.erneuerbareenergien.schluetersche.de/files/smfiledata/4/7/8/6/3/2/114bSWRcaseUSA.pdf
In conclusion Richard’s document has some good physics in it, but is missing some crucial factors which causes his conclusions to be wrong.
Climate Pete:
You ask the mistaken question and say
NO!
The big factor that you ignore – although you state it – is
wind power is proportional to the cube of the wind speed.
Wind is rarely constant and often gusts. So, if a wind turbine is not to spin out of control it requires a large safety factor on its acceptable high wind speed. This is true whatever the size of a turbine, and it means a wind turbine operates for less than half the time (usually less than 30% of the time). Indeed, you admit this and say you hope
So, following 3.5 millennia of development, in the “next generation but one” of wind turbines you hope there will be a “revolution” which will enable wind turbines to operate for slightly more than half the time “in 2m square km of the best USA wind areas”.
I assume these revolutionary turbines will swat pigs instead of birds as they fly by.
Whether or not your hope of some turbines operating for 60% of the time is ever fulfilled, wind power is ridiculously intermittent and so is an unreliable addition to a grid supply which needs to provide power to match demand.
Hence, wind power is a nuisance to a grid operator who would rarely use it if he were not mandated to.
Richard
Hello, Pete? The industry is collapsing despite mandates and subsidies.
=========
I wonder how the narrative from the left would change if they weren’t wind farms scattered over the countryside but mobile phone towers
I know how. I’ve made that same point several time the answer is always the same “but cell towers are ugly and windmills are beautiful.”
In Ontario, the Liberal government paid a South Korean company to build 40 plus wind farms and counting. All in rural farm land areas. People have had to walk away from their homes. They could not live there anymore. But the cities keep electing the Liberals. Now municipalities are no longer allowed a say in wind farm layout. Wind farms have increased electricity prices from .04 cents KWH to 29 cents a KWH in 12 years. The Liberals promise it will double. At present 10% of Ontario citizens can no longer afford electricity.
It is time they built the rest of the wind farms in the cities, esp in the rich parts where the Liberals live. One in each backyard in the Bridlepath.
We keep being told that windfarm syndrome is a symptom of jealousy ie. jealous neighbours envious that they have not been chosen to host turbines. Have a read of the following these people are being paid $200,000 a year to host turbines.

How come no one ever considers the energy required to come up with a monetary subsidy, at some level it is the output of real work. You can be sure that energy primarily comes from burning fossil fuels and nuclear power. Just saying…
Some responses to Richard Courtney….
How fast is fast-start fossil fuel generation?
http://www.energy.siemens.com/br/pool/hq/power-generation/power-plants/gas-fired-power-plants/combined-cycle-powerplants/Fast_cycling_and_rapid_start-up_US.pdf
This Siemens document talks about a design of a 40 minute start time from cold for a combined cycle gas turbine system. They also claim that a plant tested started in 30 minutes, while still achieving a 59% net efficiency.
Richard seemed to think fossil fuel generation start should take days. This well might have been true for much older coal plants.
To put this into context, here is a chart giving the predictability of wind power at various times in advance.
http://www.businessspectator.com.au/sites/default/files/styles/full_width/public/forecasting%20error.png
You can see that one hour ahead wind is predictable to less than 4% of rated capacity. To do this well you have to pay weather forecasters for the required wind speed information. The larger the area over which your wind power is aggregated, the better the forecast will be. Solar power predictability is comparable – after all, you know when it is day and when night, so all you have to work out is the clouds.
Clearly a combination of a fast start Siemens CCGT plant and a corresponding nameplate capacity of wind farms will work pretty well together.
How do wind and solar LCOE prices currently compare with fossil fuel variable (mainly fuel) costs?
http://api.ning.com/files/PPvr8qsXbQmWJ543dyFtSV5d1B86gBEHqzx0Jg0yEHB7rnAuG*K631Tm3x9xH-NSVmFAFlQfNT-*w1T77–YIeK-U4heQgXK/lcoe20152019WithFuelCostBars.png
The black bars under gas and coal are the EIA variable costs which are mostly fuel.
Are there interests to declare conflicts of interest floating around here?
My income comes from the pension as a result of 34 years work for a large IT company. As part of this work I provided two years of support to each of MANWEB (Merseyside and North Wales Electricity Board) in the early 1980s and to Shell six years late. I am now a self-funded, part-time PhD student (paying around £2000 in annual fees) in condensed matter physics at Imperial College London, and have been paid small sums by them for normal PhD student demonstrating work to undergraduates. I thus have no financial ties to the energy industry.
Richard’s document contains the following paragraph “Richard is a respected authority on energy issues, especially clean coal technology. He has been the Senior Materials Scientist of the UK’s Coal Research Establishment, has served as a Technical Advisor to the European Coal and Steel Community (ECSC), possesses several patents, and has published papers in many journals including Nature, Microscopy and Filtration. He is the author of the chapter on coal in Kempes Engineers Yearbook.”
How funny you are. No one suspects you of conflict of interest ties to the fossil fuel industry, but your disclaimer is as amusing as it is revelatory.
===============
Kim, last time I looked there was an accusation in a post not that far above which accused me of being a paid schill for the wind industry – hence my response above. Now it seems to have disappeared. Since I am not aware that normal users can edit posts once posted, presumably this was removed by a moderator.
Keep talkin’.
=========
Pete,
Germany has 23K+ wind mills. Roughly 35,000 MW of installed capacity. The average capacity factor is 17-19% based on an average of the last three years of generation. As a PhD student why don’t you use actual data rather than a EPA and Lazard report (their key assumption around wind is it’s capacity factor is closer to 30-40%.) That one fact roughly doubles the cost of wind power in your chart. Please update the chart accordingly and resubmit to WUWT.
Because Germany went hell for leather very early for renewables, and hence does not have a high proportion of state of the art wind turbines installed.
Lazard uses a factor of 30-40% because that is what modern wind turbines installed recently actually achieve in production. There are no large modern turbines installed in decent locations with capacity factors as low as 17-19%.
If you are going to go by actual data then you ought to be very careful to make sure you only include the latest wind technology.
Your figure of 17-19% is averaging capacity factors back twenty years or more. This is more of the same as Richard who is attacking new wind installation based on very old capacity factors from 2003 backwards.
How are the figures for old technology relevant to the next set of wind farm installations? They are not. You want up-to-date figures to make the next decision.
The chart is very explicit. It is for costs of installing wind equipment in the time frame of 2015 to 2019. if you want a chart of the outdate but still used turbines then produce it yourself. That chart took me a few days of Java graphics programming but I can now produce modified versions very quickly.
Further the chart gives the sources for ever figure used in its production.
Pete,
Natural Gas is about 33% cheaper than the your projections right now, maybe you should update that for your thesis too.
When using commodity prices such as natural gas you have to price in future price risk too. You can hedge against it, which gives you a fixed future price. This is what you should use in your costs case, not current commodity prices, but prices plus hedging.
A good example of the price variability effect made itself felt when Georgetown, Texas was looking to sign a 20 or 25 year power contract. They went for renewables in the end, not because of any commitment to reducing emissions, but because the providers were willing to commit to power prices 20 years out. Shale gas generation was similarly priced short-term, but suppliers would only commit to a 5 or 6 year contract, because no supplier believed gas prices would stay low long enough to commit to a 20 or 25 year contract.
So Georgetown ended up 100% renewables, not because it wanted that, but because it made commercial sense to lock in the low fixed price of renewables for 25 years.
http://thinkprogress.org/climate/2015/06/11/3666649/georgetown-texas-one-hundred-percent-renewable/
Incidentally, climate change and energy is my hobby, and nothing to do with my thesis topic. Imperial College London has both the Energy Futures Lab and the Grantham Institute for Climate Change and I regularly attend the seminary for each of these organisations. Not that they go into the level of detail of stuff I’ve been posting here, but they do give a very good overview level of what is going on.
Now I know you meant ‘seminars’ but I’m still laughing myself silly.
===============
Nice spot!
Climate Pete:
You cite a Siemens advertising blurb as suggesting a CCGT plant “tested started in 30 minutes, while still achieving a 59% net efficiency”.
Well, I have two responses (other than I don’t believe it) to that claim.
Firstly, if it is true then wind power would still be an unnecessary additional cost.
Why shut down the CCGT plant to make room for the more costly wind power?
Secondly, the UK government is providing diesel generators for rapid start-up of back-up for wind farms.
Why do you think the diesel generators are being installed instead of the cheaper and more efficient CCGT plants (available ‘off the shelf’ for construction in 18 months) if the CCGT can start-up adequately fast?
Richard

Apologies,
Things clearly have been moving very fast on this thread and I clearly didn’t look far enough up. Neither did Kim.
