Inconvenient wind turbine facts

From CFACT

By Craig Rucker

Wind turbines are intermittent, inefficient, labor-and resource-intensive, and require a tremendous footprint on land or water.

These massive turbines extract a heavy toll on eagles, hawks, birds, bats, and marine life.

On Saturday, I had the honor of joining a passionate group of nature and energy advocates at the Oklahoma State Capitol to declare a resounding “NO!” to the rapid push to erect large-scale industrial turbines across eastern Oklahoma.

Some attendees said they viewed the event as a “turning point” in the fight to preserve Oklahoma’s rural character and protect residents and wildlife from federal and state subsidized industrial overreach.

CFACT Senior Advisor David Wojick is a civil engineer with a Ph.D. in logic and analytic philosophy of science. He is a brilliant mathematician and policy analyst.

For years, David has been leading the way in analyzing the hard, inconvenient data on wind and solar energy, along with a host of other counterproductive government initiatives.

David Wojick’s work with CFACT has been having a profound positive impact on federal, state, and local energy and environmental policy.

Just this week, David posted a report to CFACT.org on a hearing in the House of Representatives on the Migratory Bird Treaty Act, which was designed to protect and preserve our birds.

An important topic was the accidental killing of birds, which David explains is called “incidental taking” by the bureaucrats. As David wryly observes, “It is not incidental to the bird, just to the operation of the facility.”

Are you surprised that the hearing somehow managed to skip, bypass, or outright ignore the massive “incidental taking” of birds and bats by wind turbines?

Not only do wind turbines strike eagles, hawks, birds, and bats out of the sky, once you erect them, many species abandon the area, never to return.

Abundant, affordable electricity is essential to human well-being in a modern society. Wind and solar increase costs, weaken the grid, require 24/7 backup from reliable sources, and impose a far dirtier environmental footprint than their advocates would have you know.

Intermittent wind and solar should not get a pass on environmental rules that are zealously enforced against efficient energy sources.

Over the lifespan of reliable Gas and Nuclear, MW for MW, wind is far more costly…3 times more costly than Gas/Coal and 4 times more costly than Nuclear. Perhaps even more so when Wind’s dismal 40% capacity factor is compared to Nuclear’s 98% capacity factor. Nuclear works when the wind doesn’t blow as well as when it blows a gale…regardless of time of day.

Writing such statements is deceptive. It gives the appearance that wind generators are useful. THEY ARE NOT USEFUL. They are a crime against humanity. Denuding landscapes of forests and fauna.

Wind over the entire Australian continent takes two weeks annual leave in early June.

To supply the existing 20GW of average demand on the east coast for two weeks requires a battery of 7TWh. At installed cost of 50c/Wh, that amounts to $3.5tr.

It is way lower cost to put solar panels on every roof and battery on the back wall. More than half of Australian homes already have the solar panels and quite a few have a battery.

But the really crazy part is that Australia produced base load electricity for $23/MWh back in 2003. Just over two decades to destroy the economy based on the fable that wind turbines are in any way useful. The are bird mincers, which is not beneficial.

“To supply the existing 20GW of average demand on the east coast for two weeks requires a battery of 7TWh. At installed cost of 50c/Wh, that amounts to $3.5tr.”

It also requires a source of 7TWh of electricity to charge it which it will not get in June, and at many other times. How many more windmills and solar panels would be required to supply the grid and charge it simultaneously? Many people who advocate batteries forget or don’t know that batteries don’t make electricity.

A dead battery cannot supply any load. How does one manage battery operation with an unpredictable intermittent energy source?
I have not seen any analysis or calculation method of how this could be done.

Here in the US Northwest, seasonal variation of wind and solar far outstrips day-to-day operational variation. During the winter, capacity factors for both wind and solar can fall below 5% each for periods lasting ten to fifteen days, occasionally as long as twenty days.

So to use wind and solar as reliable baseload power generation 24/7/365 throughout the year, lots of additional battery capacity is needed over and above what daily operational requirements specified on annual averages would require.

My estimate for maintaining 3,000 MW of true baseload 24/7/365 in the US Northwest using 9,000 MW nameplate of wind and 9,000 MW nameplate of solar requires battery storage capacity on the order of 3.6 terawatt-hours in any average year.

Fully-loaded installed cost for that much battery capacity might approach $2 trillion USD. And that is for capacity needed in an average year. For the outlier years, every decade or so, 3.6 TWh isn’t enough and battery storage is fully exhausted for periods of a week or longer.

You need Overcapacity Dedicated to recharging the back-up battery. And, in the case of solar, sufficient overcapacity to allow the battery to be recharged in 4 hours.

Yes, cost price and value are two different things. Wind and solar energy are often sold at negative pricing in open markets. Energy that cannot respond to load demand is mostly worthless.
Even freshet hydro generation is often hard to sell.
Comparing pricing with dispatch-able energy is just stupidity.

And then there’s the really silly part: big ones need to keep spinning simply to prevent excessive deformation. Even if this requires consuming power when wind happens to be too weak.

bird mincers, which is not beneficial.

Well, it’s not beneficial for birds, or most humans. For the bureaucrats a solution to some made-up problem that creates real problems is the golden goose. Just blame the decline of birds (and/or the consequences) on ManBearPig and demand more committees and funding. This cancer can expand ad infinitum or maybe until lamp posts are repurposed to deal with the underlying problem.

The incremental cost of adding wind and/or solar to a grid should be a separate line item on each and every electric bill sent to homes and businesses.

And every time those Wind and solar installations are replaced, they are replaced mat the 15-20 year inflated cost, not the current cost.
For Wind it would be 2045 $$$ then 2065 $$$ then 2085 $$$
For Solar it would be 2040 $$$ then 2055 $$$ then 2070 $$$ then 2085 $$$ then…
Who can predict the next damaging hail storm but probably several times in between as well

I don’t know who can predict the next hail storm but I imagine that insurance is available … so that the annual premium could be added as a line item to customer electric bills.

Not so sure. Insurers are being told they can selectively drop certain classes of insured if the risk is too costly. Tough to get fire insurance in the Palisades area!
Since the Jan 2025 fire, Of the 6822 insured buildings in the Palisades area less than 30 have been rebuilt. And being California all.would have been insured.

The weird thing about this is that there is no logical connexion between a belief in CAGW and a belief in the efficacy and cost-effectiveness of wind as a generating technology. Yet they are both invariably found together. You never find true believers in CAGW who will allow any skepticism about wind. Maybe there are more wind believers than just the CAGW committed? Probably, as the belief in CAGW dies it seems to be leaving behind it a belief in wind, like the Cheshire Cat’s grin.

If wind were so great, it should be in demand regardless of what you think about the climate. It should be so effective and so cheap that the utilities spontaneously all go for it, just as they did for gas. Also, regardless of whether it is in reality any use as a generating technology, its surely clear that even universal adoption of it, if it worked, would have no material effect on emissions, partly because of the need for gas in addition to make it dispatchable, partly because power generation anyway only accounts for a fraction of emissions.

The enthusiasts’ argument seems to be that its so cheap we have to subsidize it and so effective we have to compel people by law to use it. As for the effects on the climate of doing this…? Well, stop talking about that!

One of the great mass manias in human history. Maybe not as great or as damaging or as wicked as the wars and genocides, but well up there on the scale of irrationality and expense. Hasn’t killed as many as the Great Leap Forward, or agriculture collectivization, but is of the same level of irrationality and gap between supposed end and means to it.

The principal argument for wind and solar made by their advocates has shifted with the political winds and is now focused on the energy affordability crisis. Wind and solar are now promoted as being considerably cheaper than gas, coal, and nuclear. Off-year elections in 2025 here in the US demonstrate that this argument is resonating among low information voters and will be an influential factor in the upcoming 2026 mid-terms.

Overlooking the health effects of noise and infrasound is part of the mass mania.

Here’s an idea … require every new single-family home, multi-family home and apartment to get all its electricity from solar cells and/or a windmill located on the property. Think of all the copper wire we wouldn’t have to manufacture …

Copilot AI tells us …

“Total Energy to Produce Copper Wire (U.S. Typical Values)Approximate total: 82–95 million Btu per ton of finished copper wire
(≈ 24–28 MWh per metric ton)
This includes:

  • Mining: ~20 million Btu/ton
  • Milling / Concentrating: ~40–43 million Btu/ton
  • Smelting + Refining: ~20–25 million Btu/ton
  • Wire rod casting + wire drawing: ~2–5 million Btu/ton

These values come from U.S. copper industry energy audits and engineering tables.”

But then there are the batteries. But gone is the cost of burying and maintaining all the copper wire currently used to get today’s electricity from the generator to our houses, apartments and businesses …

Distribution uses pretty well all aluminium conductors except for the transformers.
Buildings are mostly wired with copper.

As well as the birds and bats can I put in a word for the flying insects. Michael Shellenberger in his ‘Apocalypse Never’ quotes Dr Franz Trieb of the German Institute of Engineering Thermodynamics.

“Wind-rich migration trails used by insects for millions of years are increasingly seamed by wind farms” A “rough but conservative estimate of the impact on flying insects in Germany” is a “loss of about 1.2 trillion insects of different species per year which could be relevant for population stability”

In earlier research Trieb also found that the build up of dead insects on wind turbine blades could reduce the electricity they produce by 50%.

Flying insects are also important pollinators.

John Christy : If it’s not economically sustainable , it’s not sustainable .

From the get-go I saw the maintenance of tens of thousands of environmentally exposed units , whose only value , as I see Alex Epstein also points out , is fuel savings , as being economically unsustainable .

Unfortunately fuel saving is not their purpose. They are CO2 emission reduction technologies so their inefficiency as power sources is irrelevant to that purpose. According to CAGW the economics of the end of civilization is the absurd issue.
