Monumental, Unsustainable Environmental Impacts

Replacing fossil fuels with renewable energy would inflict major land, wildlife, resource damage

Paul Driessen

Demands that the world replace fossil fuels with wind, solar and biofuel energy – to prevent supposed catastrophes caused by manmade global warming and climate change – ignore three fundamental flaws.

1) In the Real World outside the realm of computer models, the unprecedented warming and disasters are simply not happening: not with temperatures, rising seas, extreme weather or other alleged problems.

2) The process of convicting oil, gas, coal and carbon dioxide emissions of climate cataclysms has been unscientific and disingenuous. It ignores fluctuations in solar energy, cosmic rays, oceanic currents and multiple other powerful natural forces that have controlled Earth’s climate since the dawn of time, dwarfing any role played by CO2. It ignores the enormous benefits of carbon-based energy that created and still powers the modern world, and continues to lift billions out of poverty, disease and early death.

It assigns only costs to carbon dioxide emissions, and ignores how rising atmospheric levels of this plant-fertilizing molecule are reducing deserts and improving forests, grasslands, drought resistance, crop yields and human nutrition. It also ignores the huge costs inflicted by anti-carbon restrictions that drive up energy prices, kill jobs, and fall hardest on poor, minority and blue-collar families in industrialized nations – and perpetuate poverty, misery, disease, malnutrition and early death in developing countries.

3) Renewable energy proponents pay little or no attention to the land and raw material requirements, and associated environmental impacts, of wind, solar and biofuel programs on scales required to meet mankind’s current and growing energy needs, especially as poor countries improve their living standards.

We properly insist on multiple detailed studies of every oil, gas, coal, pipeline, refinery, power plant and other fossil fuel project. Until recently, however, even the most absurd catastrophic climate change claims behind renewable energy programs, mandates and subsidies could not be questioned.

Just as bad, climate campaigners, government agencies and courts have never examined the land use, raw material, energy, water, wildlife, human health and other impacts of supposed wind, solar, biofuel and battery alternatives to fossil fuels – or of the transmission lines and other systems needed to carry electricity and liquid and gaseous renewable fuels thousands of miles to cities, towns and farms.

It is essential that we conduct rigorous studies now, before pushing further ahead. The Environmental Protection Agency, Department of Energy and Interior Department should do so immediately. States, other nations, private sector companies, think tanks and NGOs can and should do their own analyses. The studies can blithely assume these expensive, intermittent, weather-dependent alternatives can actually replace fossil fuels. But they need to assess the environmental impacts of doing so.

Renewable energy companies, industries and advocates are notorious for hiding, minimizing, obfuscating or misrepresenting their environmental and human health impacts. They demand and receive exemptions from health and endangered species laws that apply to other industries. They make promises they cannot keep about being able to safely replace fossil fuels that now provide over 80% of US and global energy.

A few articles have noted some of the serious environmental, toxic/radioactive waste, human health and child labor issues inherent in mining rare earth and cobalt/lithium deposits. However, we now need quantitative studies – detailed, rigorous, honest, transparent, cradle-to-grave, peer-reviewed analyses.

The back-of-the-envelope calculations that follow provide a template. I cannot vouch for any of them. But our governments need to conduct full-blown studies forthwith – before they commit us to spending tens of trillions of dollars on renewable energy schemes, mandates and subsidies that could blanket continents with wind turbines, solar panels, biofuel crops and battery arrays; destroy habitats and wildlife; kill jobs, impoverish families and bankrupt economies; impair our livelihoods, living standards and liberties; and put our lives under the control of unelected, unaccountable state, federal and international rulers – without having a clue whether these supposed alternatives are remotely economical or sustainable.

Ethanol derived from corn grown on 40,000,000 acres now provides the equivalent of 10% of US gasoline – and requires billions of gallons of water, and enormous quantities of fertilizer and energy. What would it take to replace 100% of US gasoline? To replace the entire world’s motor fuels?

Solar panels on Nevada’s Nellis Air Force Base generate 15 megawatts of electricity perhaps 30% of the year from 140 acres. Arizona’s Palo Verde nuclear power plant generates 900 times more electricity, from less land, some 95% of the year. Generating Palo Verde’s output via Nellis technology would require land area ten times larger than Washington, DC – and would still provide electricity unpredictably only 30% of the time. Now run those solar numbers for the 3.5 billion megawatt-hours generated nationwide in 2016.

Modern coal or gas-fired power plants use less than 300 acres to generate 600 megawatts 95% of the time. Indiana’s 600-MW Fowler Ridge wind farm covers 50,000 acres and generates electricity about 30% of the year. Calculate the turbine and acreage requirements for 3.5 billion MWH of wind electricity.

Delving more deeply, generating 20% of US electricity with wind power would require up to 185,000 1.5-MW turbines, 19,000 miles of new transmission lines, 18 million acres, and 245 million tons of concrete, steel, copper, fiberglass and rare earths – plus fossil-fuel back-up generators for the 75-80% of the year that winds nationwide are barely blowing and the turbines are not producing electricity.

Energy analyst David Wells has calculated that replacing 160,000 teraWatt-hours of total global energy consumption with wind would require 183,400,000 turbines needing roughly: 461,000,000,000 tons of steel for the towers; 460,00,000,000 tons of steel and concrete for the foundations; 59,000,000,000 tons of copper, steel and alloys for the turbines; 738,000,000 tons of neodymium for turbine magnets; 14,700,000,000 tons of steel and complex composite materials for the nacelles; 11,000,000,000 tons of complex petroleum-based composites for the rotors; and massive quantities of other raw materials – all of which must be mined, processed, manufactured into finished products and shipped around the world.

Assuming 25 acres per turbine, the turbines would require 4,585,000,000 acres (1,855,500,000 hectares) – 1.3 times the land area of North America! Wells adds: Shipping just the iron ore to build the turbines would require nearly 3 million voyages in huge ships that would consume 13 billion tons of bunker fuel (heavy oil) in the process. And converting that ore to iron and steel would require 473 billion tons of coking coal, demanding another 1.2 million sea voyages, consuming another 6 billion tons of bunker fuel.

For sustainability disciples: Does Earth have enough of these raw materials for this transformation?

It gets worse. These numbers do not include the ultra-long transmission lines required to carry electricity from windy locations to distant cities. Moreover, Irina Slav notes, wind turbines, solar panels and solar thermal installations cannot produce high enough heat to melt silica, iron or other metals, and certainly cannot generate the required power on a reliable enough basis to operate smelters and factories.

Wind turbines (and solar panels) last just 20 years or so (less in salt water environments) – while coal, gas and nuclear power plants last 35-50 years and require far less land and raw materials. That means we would have tear down, haul away and replace far more “renewable” generators twice as often; dispose of or recycle their component parts (and toxic or radioactive wastes); and mine, process and ship more ores.

Finally, their intermittent electricity output means they couldn’t guarantee you could boil an egg, run an assembly line, surf the internet or complete a heart transplant when you need to. So we store their output in massive battery arrays, you say. OK. Let’s calculate the land, energy and raw materials for that. While we’re at it, let’s add in the requirements for building and recharging 100% electric vehicle fleets.

Then there are the bird and bat deaths, wildlife losses from destroying habitats, and human health impacts from wind turbine noise and flicker. These also need to be examined – fully and honestly – along with the effects of skyrocketing renewable energy prices on every aspect of this transition and our lives.

But for honest, evenhanded EPA and other scientists, modelers and regulators previously engaged in alarmist, biased climate chaos studies, these analyses will provide some job security. Let’s get started.

If the article had left out the vacuous points 1 and 2, and started in at point 3 – “Renewable energy proponents pay little or no attention to the land and raw material requirements, and associated environmental impacts, of wind, solar and biofuel programs on scales required to meet mankind’s current and growing energy needs”
it would have been a much better, and more widely read, contribution to debate.

Is the data available on the total number of megawatt-hours of electricity fed into the Canadian grid by the Cowley Ridge Wind Farm during its 23 year lifetime?
This is an essential component needed to compute the energy return on energy investment, i.e. the electrical energy generated compared with the energy needed to establish, maintain and dismantle the same wind-farm.
The reason this ratio is important is that the whole global economy works on the basis of energy provided by the 9% of the economy which is the energy generation and distribution sector. This sector has a return ratio of 11 to 1.
If the windfarm did better than this the world economy can accomplish more, if worse than this, the world economy must shrink.

TransAlta claims the wind farm was producing 53,500 MW-hr per year with a name plate capacity of 19.5 MW. That would be an average of about 2,750 hours per year, or a capacity factor of about 31.2%. The rest is left as an exercise for the student.

SUSTAINABLE REALITY
If you like your energy sustainable,
You must first make the climate trainable.
With sun day and night,
And the wind always right…
I think it just might be attainable!
Solar and wind are renewable,
But only on small scales prove doable
They can kill birds and bats
And displace habitats…
True ecologists find that eschew-able.
We would, likely, employ keener vision
Funding hydro and nuclear fission.
(The molten salt kind,
For our peace of mind)
And solar storm-proofed grids of transmission.
Affordable energy, for the third world poor
Will unlock that vital, virtual door
To an affluent life,
A job and a wife
With less children than folks raised before.
So, curtailing overpopulation
Is not about “limiting nations
On what they can do
Which emits CO2”…
It relies on industrialization!

So far from the fairyland fantasy that advocates of wind turbines live in with little to commend them except as subsidy farming implements, the fast developing North Sea windmill comedy proceeds apace. Within two years of their installation and the alledged twenty five year lifespan these turkey masts were supposed to last, more than a 120 are already coming loose from their seabed foundations and developing dysfunctional leans.
This is going to prove horribly expensive for someone and those foolish enough to have provided insurance for these looney towers in the expectation of reasonable profits are developing a sweat and looking to unload the costs – three guesses who is going to be asked to bail them out.
At costs of some £50k a day for the barge that is required to grab each of the leaning each towers of the North Sea while its adjustable bolts are readjusted this is going to be a costly and unending task, assuming the erosion beneath the base isn’t so far gone repair is still possible.
And to add to the catalogue of failings I suggest Griffy takes a look at the latest pictures from NASA of the plumes of sand and mud being washed out from the wind farms trailing debris 20 to 25 miles from each subsidy farm. As these farms are located on shallower plateaus which fish also need to spawn, washing a rain of displaced debris and then running heavyweight barges over these banks is doing no end of good for fish stock futures. But hey, out of sight, out of mind!
But still we can close our eyes and mind and believe these monstrous wastes of money are any kind of use in providing any kind of future. Or we can look at reality and stop snorting fairy dust or lining our pockets with poor people’s money…delete as appropriate.

They are not coming loose from their foundations…
I believe at most a couple of sites have had problems in the past… but new technology, monitoring etc proceeds and this is unlikely to be a problem in the future. You tell me how many this has actually happened on – there are over 3,500 offshore turbines in Europe.
A Danish offshore wind farm just got retired after working successfully since 1991
http://www.maritime-executive.com/article/worlds-first-offshore-wind-farm-being-decommissioned
Evidence suggests offshore wind is good for fish and seals after construction finishes… fishing boats can’t get close to the turbines, providing a refuge. As you should know, seals off Norfolk have been tracked preferentially feeding around the Sheringham shoals wind farm…

Funny, a couple of bad things happen with oil and gas, and the enviros scream. Let a few wind turbines burn, fall over, throw blades, kill raptors and “no big deal”. Methinks it’s not about bad things happening, but rather about the faith one has in their unfailing support for a failed idea.

July 5, 2017 1:44 pm

Driessen is at his comic best on this one. Environmental damage from wind turbines? Really?
I suppose all those 90,000 wind turbines installed in the US up to now (approximate number) never had an EIR study. That’s a mandated Environmental Impact Report.
Very strange, it is, that no Environmentalst anywhere found an environment impact that could block the turbine installations.
The EIRs are public information. One could look them up.
Driessen is hilarious. And very, very wrong.

EIR and EIS for federal projects, describe in great detail the impacts on many aspects of the environment. One could look it up.
Let’s name a few of the environmental impacts we DONT see from wind farms:
Radiation, acidic releases into waterways, soapy or organic foams into waterways, hydrocarbon leaks or spills into the ground, particulate matter (PM, whether PM10 or PM2.5) released into the air, lead poisons into the ground or water, PCBs, arsenic, elevated cooling water temperatures of lakes or rivers or oceans, NOx and SOx emissions.
Instead, wind farms allow approximately 95 percent of the surrounding land to continue with whatever activity was there before: growing crops, grazing cattle or other livestock.
In many cases, the wind turbines are placed on marginal land (along ridges) that have zero other uses.
For Paul Penrose re finding EIRs to read, I am no Harry Potter in Internet searching, yet I manage to find hundreds of wind-farm EIRs quite easily. Of course, I actually type the words into a search engine and hit ENTER. Just a thought.

Reply to  Roger Sowell
July 6, 2017 12:39 pm

Did I mention other environmental impacts that wind turbines DONT have?
No mining for coal to burn, no transporting coal via noisy trains, no miner deaths in the mines, no mining and processing uranium into fissible material with all the environmental degradation that entails, no birds killed from high-speed collisions with giant cooling tower structures (like at Nuclear Plants).
Why is it the anti-wind crowd is so opposed to the few birds killed by old-style wind turbines, but are perfectly ok with all the birds killed by impact with power plant smokestacks and nuclear plant cooling towers?
I’ve always wondered why some birds are more important than others.

What I find particularly disturbing is that the CBC national broadcaster, has the headline: Seeing the light: Oilsands, mining companies watch B.C. solar project with intrigue
It was basically bankrupt before being built, and I understand the city of Kimberly has been trying to sell the project to the private sector, but no takers yet.
Let’s just deal with the raw economics of this recent 1 Mw solar PV installation in Kimberly, BC. $5.3 Mil Cdn to build a 1 Mw name plate project. That is extremely expensive even if it produced electricity 95% of the time. But it only has (at most) about a yearly 23% efficiency factor. Probably more about 20% if the maintenance and repairs are factored in. So on a yearly average of 8760 total hours, at best, it can only deliver about 2,200 Mw/hr which even at a retail price of $100 per Mw/hr, makes for gross earnings of $220,000 per year on a $5.3 Mil up front sunk capital cost. With a 20-25 year lifespan (if lucky) and declining output over the years, this clearly doesn’t add up for any kind of ROI for a grid connected install that justifies this project. This would be equivalent to spending well over $20 Mil per 1 Mw of base load up time 95% capacity factor from a Nat Gas install. Clearly, the economics just don’t work yet for this type of renewable energy. Maybe for a remote off grid site like an aboriginal reservation on diesel power, but this doesn’t make economic sense to subsidize this type of grid connected renewable energy.

After all this discusasion can we at least drive a nail into the coffin of biofuel. It produces little if any savings in CO2 releases, it costs too much, it uses too much water, its excessive fertiler needs produces polluted run- off water and it drives up the costs of corn, meat and many other foods. There is no need to extend our gasoline supply. All federal subsidies and incentives have to stop, and the whole idea needs to have a stake driven through its heart. As a bonus maybe we can save the Monarch Butterfly.

David Wells’ numbers on wind turbines strike me as way off. Assuming 2 MW turbines operating at 24% capacity factor, 160,000 TW-hr total output would require 38,052,000 turbines, not 183,401,000. The total weight of materials he gives for the turbine itself (tower, nacelle, blades, generator) is 546.9 billion tons. that would put the weight of each turbine (assuming his number is correct) at 2,991 tons. The weight of an actual 2 MW turbine, the Gamesa G87 (https://en.wind-turbine-models.com/turbines/548-gamesa-g87) is given by the manufacturer as 386 t (which, I assume, is metric, making it equal to 425.6 short tons). According to this site (https://www.wind-watch.org/faq-size.php), the base weight is over 1,000 tons of steel reinforced concrete. To me, as an engineer, that sounds more reasonable than the 2,500 tons Mr. Wells’ figures imply.
On the other hand, the spacing requirements for wind farm (10 rotor diameters stream-wise, 3 laterally) for the 87 meter diameter Gamesa would give a farm size (using my numbers) of 3.34 million square miles. That’s 88% of the land area of the United States. Further, according to this source (https://docs.wind-watch.org/Larwood-bladethrow-paper.pdf, page 12), the probability of a blade throw is somewhere around 0.001 to 0.01 per turbine per year. We would then expect from 38,000 to 380,000 cases per year of a 6.2 tonne (6.84 short ton) blade being chucked through the air. That’s like the crash of a Cessna Citation 525 CJ3+ business jet. Imagine 38,000 to 380,000 of those every year, and what the probability of casualty would be.
Mr. Wells may have overestimated things, but that doesn’t mean that there’s anything sane or sustainable about wind power.

I note that 2MW is actually small for a turbine these days and that UK onshore capacity is 27%, higher offshore at 30% (where 8MW turbines are installed).
There is a significant portion of mid-west America with 40% and better capacity.
So, given there are bigger turbines out there and higher capacities, I think the figures are even further off from David Well’s figures than your excellent summation suggests…

Michael S. Kelly
Reply to  Griff
July 7, 2017 10:05 pm

Yes, I think they are further off as well. I did a very quick search on actual turbine output and other things, and picked the 2 MW turbine mostly because it had a lot of data available. 4 MW turbines are much more common, and would drive up the total mass figures (despite slightly reducing the number of turbines required, since the base weight requirement is a function of both the mass of the turbine and its height). I’m not sure about the ubiquity of 40% capacity factor onshore in the US, thought it does seem to be available offshore in the US.
Adjusting the number of turbines for 40% rather than 24% capacity leads to a number of turbines 4 MW turbines of 11,416,000. But the argument made in the article still stands. The concrete in the bases for these turbines alone would constitute 123% of the entire world’s annual concrete production. That would have to be added on top of the current production. And, it might be noted, concrete production involves the release of a huge amount of CO2 into the atmosphere – around 900 kg/tonne of concrete. Building this infrastructure in one year would add 29% to the global CO2 emissions. But then, it couldn’t be done in a year.
The global equivalent of gross domestic product in 2017 (http://statisticstimes.com/economy/countries-by-projected-gdp.php) is estimated at $126.69 trillion. The capital cost of a large wind turbine is about $2 per watt. That amounts to $91.4 trillion, or 72% of the world GDP. Energy cost has long averaged 7% of GDP, so we would expect phasing in of wind in no less than 10 years. It would be much longer, of course, since a 10% per annum addition to capital cost is not sustainable for 10 years. The reduction in fuel cost is actually fairly small over that time.
The 800 pound gorilla in the room, however, is energy storage cost. The best we can do today is lithium ion batteries (pumped water storage would require the creation of inland oceans too large to imagine). With the very optimistic 40% wind turbine capacity factor, we would need to be able to store 60% of the energy required to run the world, or 96 billion MW-hr. Lithium-ion batteries can store about 250 W-hr/kg, so we would need 384 trillion kg of them to do the job. The low end cost today is $7.50/kg. So the battery cost would be $2,880 trillion, or 227% of the world GDP.
This is, of course, a low-ball cost. The planet simply can’t support it.

The few etailed articles on this subject that I have come across so far seem to downplay the concerns of this post — concerns such as land-area requirements and intermittent sun/wind. So, I would definitely like to see more assessments of a large-scale renewable power generating infrastructure.
One article I skimmed claims that land use per kw/hr of electricity would be about the same for solar and coal, which just seems wrong intuitively, as well as contradicting what this post claims.
Come on, folks, I want to see realistic assessments, NOT dreams that temper the harsh realities out of view. Do we really want a world of bird-blasting-whale-vibrating turbines and solar-panel-paved landscapes? … all to reduce the presence of a little atmospheric gas?

“detailed” — I know I typed “detailed”, but a gremlin must have stolen my “d”.

Umm, “known reserves” is a term that has to be understood, with emphasis on “known” then on the criteria for viability of extraction.
I am astounded at the “rare earth” mineral deposits being discovered in Ontario, Quebec, and Labrador in Canada, with serious proposals to extract and refine.
As for “alternative energy”, I want to see all-in economic calculations, which will vary for different cases. For example, BCTel/Telus has been using solar for a long time to reduce need to schlepp fuel to mountain tops to run radio repeaters – obviously a niche application where the cost of other options is very high. Similarly, Anthony Watts justified solar for the family house because the marginal rate at peak demand times was very high (IIRC $0.93 per kwh, an order of magnitude above SW B.C.). And solar, plus in a few cases wind, are being explored for remote communities now running diesel gensets, though they must include the cost of storage for such intermittent power sources. (That will depend on hilliness to build reservoirs up hills to pump water up to then run back down through turbines.) Etc.

Argue back and forth as much as you want. There will be peak oil. Demand with outstrip supply. If the alternatives are not developed & ready to take over, what then?

We’re not going to run out of fossil fuels in our lifetimes and when that day comes (if ever) we can be assured that the world will cope just fine. That’s what free markets and trade are for. Humans are inventive…that’s how we have survived and prospered so well…although the stromatolites probably just look upon us as a flash in the pan (and they would be right)!
