Appeals to reason and logic are worthless in dealing with fanatics, so it’s too bad that matters of public policy are so often subject to fanaticism. Nothing is more vulnerable on this scale than climate policy. Why else would anyone continue to listen to prognosticators of such distinguished failure as Paul Ehrlich? Perhaps most infamously, his 1970s forecasts of catastrophe due to population growth were spectacularly off-base. He’s a man without any real understanding of human behavior and how markets deal efficiently and sustainably with scarcity. Here’s a little more detail on his many misfires. And yet people believe him! That’s blind faith.

The foolish acceptance of chicken-little assertions leads to coercive and dangerous policy prescriptions. These are both unnecessary and very costly in direct and hidden ways. But we hear a frantic chorus that we’d better hurry or… we’re all gonna die! Ironically, the fate of the human race hardly matters to the most radical of the alarmists, who are concerned only that the Earth itself be in exactly the same natural state that prevailed circa 1800. People? They don’t belong here! One just can’t take this special group of fools too seriously, except that they seem to have some influence on an even more dangerous group of idiots called policymakers.

Judith Curry, an esteemed but contrarian climate expert, writes of the “faux urgency” of climate action, and how the rush to implement supposed climate mitigations is a threat to our future:

“Rapid deployment of wind and solar power has invariably increased electricity costs and reduced reliability, particularly with increasing penetration into the grid. Allegations of human rights abuses in China’s Xinjiang region, where global solar voltaic supplies are concentrated, are generating political conflicts that threaten the solar power industry. Global supply chains of materials needed to produce solar and wind energy plus battery storage are spawning new regional conflicts, logistical problems, supply shortages and rising costs. The large amount of land use required for wind and solar farms plus transmission lines is causing local land use conflicts in many regions.”

Curry also addresses the fact that international climate authorities have “moved the goalposts” in response to the realization that the so-called “crisis” is not nearly as severe as we were told not too long ago. And she has little patience for delusions that authorities can reliably force adjustments in human behavior so as to to reduce weather disasters:

“Looking back into the past, including paleoclimatic data, there has been more extreme weather [than today] everywhere on the planet. Thinking that we can minimize severe weather through using atmospheric carbon dioxide as a control knob is a fairy tale.”

The lengths to which interventionists are willing to go should make consumer/taxpayers break out their pitchforks. It’s absurd to entertain mandates forcing vehicles powered by internal combustion engines (ICEs) off the road, and automakers know it. Recently, the head of Toyota Motors acknowledged his doubts that electric vehicles (EVs) can meet our transportation demands any time soon:

“People involved in the auto industry are largely a silent majority. That silent majority is wondering whether EVs are really OK to have as a single option. But they think it’s the trend so they can’t speak out loudly. Because the right answer is still unclear, we shouldn’t limit ourselves to just one option.”

In the same article, another Toyota executive says that neither the market nor the infrastructure is ready for a massive transition to EVs, a conclusion only a dimwit could doubt. Someone should call the Big 3 American car companies!

No one is a bigger cheerleader for EVs than Elon Musk. In the article about Toyota, he is quoted thusly:

“At this time, we actually need more oil and gas, not less. Realistically I think we need to use oil and gas in the short term, because otherwise civilization will crumble. One of the biggest challenges the world has ever faced is the transition to sustainable energy and to a sustainable economy. That will take some decades to complete.”

Of course, for the foreseeable future, EVs will be powered primarily by electricity generated from burning fossil fuels. So why the fuss? But as one wag said, that’s only until the government decides to shut down those power plants. After that, good luck with your EV!

Gas stoves are a new target of our energy overlords, but this can’t be about fuel efficiency, and it’s certainly not about the quality of food preparation. The claim by an environmental think tank called “Carbon-Free Buildings” is that gas stoves are responsible for dangerous indoor pollutants. Of course, the Left was quick to rally around this made-up problem, despite the fact that they all seem to use gas stoves and didn’t know anything about the issue until yesterday! And, they insist, racial minorities are hardest hit! Well, they might consider using exhaust fans, but the racialist rejoinder is that minorities aren’t adequately informed about the dangers and mitigants. Okay, start a safe-use info campaign, but keep government away from an embedded home technology that is arguably superior to the electric alternative in several respects.

Renewable energy mandates are a major area of assault. If we were to fully rely on today’s green energy technologies, we’d not just threaten our future, but our immediate health and welfare. Few people, including politicians, have any awareness of the low rates at which green technologies are actually utilized under real-world conditions.

“Worldwide average solar natural capacity factor (CF) reaches about ~11-13%. Best locations in California, Australia, South Africa, Sahara may have above 25%, but are rare. (see www.globalsolaratlas.info, setting direct normal solar irradiance)

Worldwide average wind natural capacity factors (CF) reach about ~21-24%. Best off-shore locations in Northern Europe may reach above 40%. Most of Asia and Africa have hardly any usable wind and the average CF would be below 15%, except for small areas on parts of the coasts of South Africa and Vietnam. (see www.globalwindatlas.info, setting mean power density)”

Those CFs are natural capacity factors (i.e., the wind doesn’t always blow or blow at “optimal” speeds, and the sun doesn’t always shine or shine at the best angle), The CFs don’t even account for “non-natural” shortfalls in actual utilization and other efficiency losses. It would be impossible for investors to make these technologies profitable without considerable assistance from taxpayers, but they couldn’t care less about whether their profits are driven by markets or government fiat. You see, they really aren’t capitalists. They are rent seekers playing a negative-sum game at the expense of the broader society.

There are severe environmental costs associated with current wind and solar technologies. Awful aesthetics and the huge inefficiencies of land use are bad enough. Then there are deadly consequences for wildlife. Producing inputs to these technologies requires resource-intensive and environmentally degrading mining activities. Finally, the costs of disposing of spent, toxic components of wind turbines and solar panels are conveniently ignored in most public discussions of renewables.

There is still more hypocritical frosting on the cake. Climate alarmists are largely opposed to nuclear power, a zero-carbon and very safe energy source. They also fight to prevent development of fossil fuel energy plant for impoverished peoples around the world, which would greatly aid in economic development efforts and in fostering better and safer living conditions. Apparently, they don’t care. Climate activists can only be counted upon to insist on wasteful and unreliable renewable energy facilities.

Before concluding, it’s good to review just a few facts about the “global climate”:

1) the warming we’ve seen in forecasts and in historical surface temperature data has been distorted by urban heat island effects, and weather instruments are too often situated in local environments rich in concrete and pavement.

2) Satellite temperatures are only available for the past 43 years, and they have to be calibrated to surface measurements, so they are not independent measures. But the trend in satellite temperatures over the past seven years has been flat or negative at a time when global carbon emissions are at all-time highs.

3) There have been a series of dramatic adjustments to historical data that have “cooled the past” relative to more recent temperatures.

4) The climate models producing catastrophic long-term forecasts of temperatures have proven to be biased to the high side, having drastically over-predicted temperature trends over the past two- to three decades.

5) Sea levels have been rising for thousands of years, and we’ve seen an additional mini-rebound since the mini-ice age of a few hundred years ago. Furthermore, the rate of increase in sea levels has not accelerated in recent decades, contrary to the claims of climate alarmists.

6) Storms and violent weather have shown no increase in frequency or severity, yet models assure us that they must!

Despite these facts, climate change fanatics will only hear of climate disaster. We should be unwilling to accept the climatological nonsense now passing for “settled science”, itself a notion at odds with the philosophy of science. I’m sad to say that climate researchers are often blinded by the incentives created by publication bias and grant money from power-hungry government bureaucracies and partisan NGOs. They are so blinded, in fact, that research within the climate establishment now almost completely ignores the role of other climatological drivers such as the solar irradiance, volcanic activity, and the role and behavior of atmospheric aerosols. Yes, only the global carbon dial seems to matter!

No one is more sympathetic to “the kids” than me, and I’m sad that so much of the “fan base” for climate action is dominated by frightened members of our most youthful generations. It’s hard to blame them, however. Their fanaticism has been inculcated by a distinctly non-scientific community of educators and journalists who are willing to accept outrageous assertions based on “toy models” concocted on weak empirical grounds. That’s not settled science. It’s settled propaganda.

Wind and Solar Power: Brittle, Inefficient, and Destructive

Just how renewable is “renewable” energy, or more specifically solar and wind power? Intermittent though they are, the wind will always blow and the sun will shine (well, half a day with no clouds). So the possibility of harvesting energy from these sources is truly inexhaustible. Obviously, it also takes man-made hardware to extract electric power from sunshine and wind — physical capital— and it is quite costly in several respects, though taxpayer subsidies might make it appear cheaper to investors and (ultimately) users. Man-made hardware is damaged, wears out, malfunctions, or simply fails for all sorts of reasons, and it must be replaced from time to time. Furthermore, man-made hardware such as solar panels, wind turbines, and the expansions to the electric grid needed to bring the power to users requires vast resources and not a little in the way of fossil fuels. The word “renewable” is therefore something of a misnomer when it comes to solar and wind facilities.

Solar Plant

B. F. Randall (@Mining_Atoms) has a Twitter thread on this topic, or actually several threads (see below). The first thing he notes is that solar panels require polysilicon, which not recyclable. Disposal presents severe hazards of its own, and to replace old solar panels, polysilicon must be produced. For that, Randall says you need high-purity silica from quartzite rock, high-purity coking coal, diesel fuel, and large flows of dispatchable (not intermittent) electric power. To get quartzite, you need carbide drilling tools, which are not renewable. You also need to blast rock using ammonium nitrate fuel oil derived from fossil fuels. Then the rock must be crushed and often milled into fine sand, which requires continuous power. The high temperatures required to create silicon are achieved with coking coal, which is also used in iron and steel making, but coking coal is non-renewable. The whole process requires massive amounts of electricity generated with fossil fuels. Randall calls polysilicon production “an electricity beast”.

Greenwashing

The resulting carbon emissions are, in reality, unlikely to be offset by any quantity of carbon credits these firms might purchase, which allow them to claim a “zero footprint”. Blake Lovewall describes the sham in play here:

“The biggest and most common Carbon offset schemes are simply forests. Most of the offerings in Carbon marketplaces are forests, particularly in East Asian, African and South American nations. …

The only value being packaged and sold on these marketplaces is not cutting down the trees. Therefore, by not cutting down a forest, the company is maintaining a ‘Carbon sink’ …. One is paying the landowner for doing nothing. This logic has an acronym, and it is slapped all over these heralded offset projects: REDD. That is a UN scheme called ‘Reduce Emissions from Deforestation and Forest Degradation’. I would re-name it to, ‘Sell off indigenous forests to global investors’.”

Lovewall goes on to explain that these carbon offset investments do not ensure that forests remain pristine by any stretch of the imagination. For one thing, the requirements for managing these “preserves” are often subject to manipulation by investors working with government; as such, the credits are often vehicle for graft. In Indonesia, for example, carbon credited forests have been converted to palm oil plantations without any loss of value to the credits! Lovewall also cites a story about carbon offset investments in Brazil, where the credits provided capital for a massive dam in the middle of the rainforest. This had severe environmental and social consequences for indigenous peoples. It’s also worth noting that planting trees, wherever that might occur under carbon credits, takes many years to become a real carbon sink.

While I can’t endorse all of Lovewall’s points of view, he makes a strong case that carbon credits are a huge fraud. They do little to offset carbon generated by entities that purchase them as offsets. Again, the credits are very popular with the manufacturers and miners who participate in the fabrication of physical capital for renewable energy installations who wish to “greenwash” their activities.

Wind Plant

Randall discusses the non-renewability of wind turbines in a separate thread. Turbine blades, he writes, are made from epoxy resins, balsa wood, and thermoplastics. They wear out, along with gears and other internal parts, and must be replaced. Land disposal is safe and cheap, but recycling is costly and requires even greater energy input than the use of virgin feedstocks. Randall’s thread on turbines raised some hackles among wind energy defenders and even a few detractors, and Randall might have overstated his case in one instance, but the main thrust of his argument is irrefutable: it’s very costly to recycle these components into other usable products. Entrepreneurs are still trying to work out processes for doing so. It’s not clear that recycling the blades into other products is more efficient than sending them to landfills, as the recycling processes are resource intensive.

But even then, the turbines must be replaced. Recycling the old blades into crates and flooring and what have you, and producing new wind turbines, requires lots of power. And as Randall says, replacement turbines require huge ongoing quantities of zinc, copper, cement, and fossil fuel feedstocks.

The Non-Renewability of Plant

It shouldn’t be too surprising that renewable power machinery is not “renewable” in any sense, despite the best efforts of advocates to convince us of their ecological neutrality. Furthermore, the idea that the production of this machinery will be “zero carbon” any time in the foreseeable future is absurd. In that respect, this is about like the ridiculous claim that electric vehicles (EVs) are “zero emission”, or the fallacy that we can achieve a zero carbon world based on renewable power.

It’s time the public came to grips with the reality that our heavy investments in renewables are not “renewable” in the ecological sense. Those investments, and reinvestments, merely buy us what Randall calls “garbage energy”, by which he means that it cannot be relied upon. Burning garbage to create steam is actually a more reliable power source.

Highly Variable With Low Utilization

Randall links to information provided by Martian Data (@MartianManiac1) on Europe’s wind energy generation as of September 22, 2022 (see the tweet for Martian Data’s sources):

“Hourly wind generation in Europe for past 6 months:
Max: 122GW
Min: 10.2GW
Mean: 41.0
Installed capacity: ~236GW”

That’s a whopping 17.4% utilization factor! That’s pathetic, and it means the effective cost is quintuple the value at nameplate capacity. Take a look at this chart comparing the levels and variations in European power demand, nuclear generation, and wind generation over the six months ending September 22nd (if you have trouble zooming in here, try going to the thread):

The various colors represent different countries. Here’s a larger view of the wind component:

A stable power grid cannot be built upon this kind of intermittency. Here is another comparison that includes solar power. This chart is daily covering 2021 through about May 26, 2022.

As for solar capacity utilization, it too is unimpressive. Here is Martian Data’s note on this point, followed by a chart of solar generation over the course of a few days in June:

“so ~15% solar capacity is whole year average. ~5% winter ~20% summer. And solar is brief in summer too…, it misses both both morning and evening peaks in demand.”

Like wind, the intermittency of solar power makes it an impractical substitute for traditional power sources. Check out Martian Data’s Twitter feed for updates and charts from other parts of the world.

Nuclear Efficiency

Nuclear power generation is an excellent source of baseload power. It is dispatchable and zero carbon except at plant construction. It also has an excellent safety record, and newer, modular reactor technologies are safer yet. It is cheaper in terms of generating capacity and it is more flexible than renewables. In fact, in terms of the resource costs of nuclear power vs. renewables over plant cycles, it’s not even close. Here’s a chart recently posted by Randall showing input quantities per megawatt hour produced over the expected life of each kind of power facility (different power sources are labeled at bottom, where PV = photovoltaic (solar)):

In fairness, I’m not completely satisfied with these comparisons. They should be stated in terms of current dollar costs, which would neutralize differences in input densities and reflect relative scarcities. Nevertheless, the differences in the chart are stark. Nuclear produces cheap, reliable power.

The Real Dirt

Solar and wind power are low utilization power sources and they are intermittent. Heavy reliance on these sources creates an extremely brittle power grid. Also, we should be mindful of the vast environmental degradation caused by the mining of minerals needed to produce solar panels and wind turbines, including their inevitable replacements, not to mention the massive land use requirements of wind and solar power. Also disturbing is the hazardous dumping of old solar panels from the “first world” now taking place in less developed countries. These so-called clean-energy sources are anything but clean or efficient.
