This is a first for me…. The following is partly excerpted from a post of two weeks ago, but I’ve made a number of edits and additions. The original post was way too long. This is a bit shorter, and I hope it distills a key message.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Failures of industrial policies are nothing new, but the current manipulation of electric power generation by government in favor of renewable energy technologies is egregious. These interventions are a reaction to an overwrought climate crisis narrative, but they have many shortcomings and risks of their own. Chief among them is whether the power grid will be capable of meeting current and future demand for power while relying heavily on variable resources, namely wind and sunshine. The variability implies idle and drastically underutilized hours every day without any ability to call upon the assets to produce when needed.

The variability is vividly illustrated by the chart above showing a representative daily profile of power demand versus wind and solar output. Below, with apologies to Dante, I describe the energy hellscape into which we’re being driven on the horns of irrational capital outlays. These projects would be flatly rejected by any rational investor but for the massive subsidies afforded by government.

The First Circle of Dormancy: Low Utilization

Wind and solar power assets have relatively low rates of utilization due to the intermittency of wind and sunshine. Capacity factors for wind turbines averaged almost 36% in the U.S. in 2022, while solar facilities averaged only about 24%. This compared with nuclear power at almost 93%, natural gas (66%), and coal (48%).

Despite their low rates of utilization, new wind and solar facilities are always touted at their full nameplate capacity. We hear a great deal about “additions to capacity”, which overstate the actual power-generating potential by factors of three to four times. More importantly, this also means wind and solar power costs per unit of output are often vastly understated. These assets contribute less economic value to the electric grid than more heavily utilized generating assets.

Sometimes wind and solar facilities are completely idle or dormant. Sometimes they operate at just a fraction of capacity. I will use the terms “idle” and dormant” euphemistically in what follows to mean assets operating not just at low levels of utilization, but for those prone to low utilization and also falling within the Second Circle of Dormancy.

The Second Circle of Dormancy: Non-Dispatchability

The First Circle of Dormancy might be more like a Purgatory than a Hell. That’s because relatively low average utilization of an asset could be justifiable if demand is subject to large fluctuations. This is the often case, as with assets like roads, bridges, restaurants, amusement parks, and many others. However, capital invested in wind and solar facilities is idle on an uncontrollable basis, which is more truly condemnable. Wind and solar do not provide “dispatchable” power, meaning they are not “on call” in any sense during idle or less productive periods. Not only is their power output uncontrollable, it is not entirely predictable.

Again, variable but controllable utilization allows flexibility and risk mitigation in many applications. But when utilization levels are uncontrollable, the capital in question has greatly diminished value to the power grid and to power customers relative to dispatchable sources having equivalent capacity and utilization. It’s no wonder that low utilization, variability, and non-dispatchability are underemphasized or omitted by promoters of wind and solar energy. This sort of uncontrollable down-time is a drain on real economic returns to capital.

The Third Circle of Dormancy: Transmission Infrastructure

The idleness that besets the real economic returns to wind and solar power generation extends to the transmission facilities necessary for getting power to the grid. Transmission facilities are costly, but that cost is magnified by the broad spatial distribution of wind and solar generating units. Transmission from offshore facilities is particularly complex. When wind turbines and solar panels are dormant, so are the transmission facilities needed to reach them. Thus, low utilization and the non-dispatchability of those units diminishes the value of the capital that must be committed for both power generation and its transmission.

The Fourth Circle of Dormancy: Backup Power Assets

The reliability of the grid requires that any commitment to variable wind and solar power must also include a commitment to back-up capacity. As another example, consider shipping concerns that are now experimenting with sails on cargo ships. What is the economic value of such a ship without back-up power? Can you imagine these vessels drifting in the equatorial calms for days on end? Even light winds would slow the transport of goods significantly. Idle, non–dispatchable capital, is unproductive capital.

Likewise, solar-powered signage can underperform or fail over the course of several dark, wintry days, even with battery backup. The signage is more reliable and valuable when it is backed-up by another power source. But again, idle, non-dispatchable capital is unproductive capital.

The needed provision of backup power sources represents an imposed cost of wind and solar, which is built into the cost estimates shown in a section below. But here’s another case of dormancy: some part of the capital commitment, either primary energy sources or the needed backups, will be idle regardless of wind and solar conditions… all the time. Of course, back-up power facilities should be dispatchable because they must serve an insurance function. Backup power therefore has value in preserving the stability of the grid even while completely idle. However, at best that value offsets a small part of the social loss inherent in primary reliance on variable and non-dispatchable power sources.

We can’t wholly “replace” dispatchable generating capacity with renewables without serious negative consequences. At the same time, maintaining existing dispatchable power sources as backup carries a considerable cost at the margin for wind and solar. At a minimum, it requires normal maintenance on dispatchable generators, periodic replacement of components, and an inventory of fuel. If renewables are intended to meet growth in power demand, the imposed cost is far greater because backup sources for growth would require investment in new dispatchable capacity.

The Fifth Circle of Dormancy: Outages

The pursuit of net-zero carbon emissions via wind and solar power creates uncontrollably dormant capital, which increasingly lacks adequate backup power. Providing that backup should be a priority, but it’s not.

Perhaps much worse than the cost of providing backup power sources is the risk and imposed cost of grid instability in their absence. That cost would be borne by users in the form of outages. Users are placed at increasing risk of losing power at home, at the office and factories, at stores, in transit, and at hospitals. This can occur at peak hours or under potentially dangerous circumstances like frigid or hot weather.

Outage risks include another kind of idle capital: the potential for economy-wide shutdowns across a particular region of all electrified physical capital. Not only can grid failure lead to economy-wide idle capital, but this risk transforms all capital powered by electricity into non-dispatchable productive capacity.

Reliance on wind and solar power makes backup capacity an imperative. Better still, just scuttle the wind and solar binge and provide for growth with reliable sources of power!

Quantifying Infernal Costs

A “grid report card“ from the Mackinac Center for Public Policy gets right to the crux of the imposed-cost problem:

“… the more renewable generation facilities you build, the more it costs the system to make up for their variability, and the less value they provide to electricity markets.”

The report card uses cost estimates for Michigan from the Center of the American Experiment. Here are the report’s average costs per MWh through 2050, including the imposed costs of backup power:

—Existing coal plant: $33/MWh

—Existing gas-powered: $22

— New wind: $180

—New solar: $278

—New nuclear reactor (light water): $74

—Small modular reactor: $185

—New coal plant: $106 with carbon capture and storage (CCS)

—New natural gas: $64 with CCS

It’s should be no surprise that existing coal and gas facilities are the most cost effective. Preserve them! Of the new installations, natural gas is the least costly, followed by the light water reactor and coal. New wind and solar capacity are particularly costly.

Proponents of net zero are loath to recognize the imposed cost of backup power for two reasons. First, it is a real cost that can be avoided by society only at the risk of grid instability, something they’d like to ignore. To them, it represents something of an avoidable external cost. Second, at present, backup dispatchable power would almost certainly entail CO2 emissions, violating the net zero dictum. But in attempting to address a presumed externality (climate warming) by granting generous subsidies to wind and solar investors, the government and NGOs induce an imposed cost on society with far more serious and immediate consequences.

Deadly Sin: Subsidizing Dormant Capital

Wind and solar capital outlays are funded via combinations of private investment and public subsidies, and the former is very much contingent on the latter. That’s because the flood of subsidies is what allows private investors a chance to profit from uncontrollably dormant capital. Wind and solar power are far more heavily subsidized than fossil fuels, as noted by Mitch Rolling and Isaac Orr:

“In 2022, wind and solar generators received three and eighteen times more subsidies per MWh, respectively, than natural gas, coal, and nuclear generators combined. Solar is the clear leader, receiving anywhere from $50 to $80 per MWh over the last five years, whereas wind is a distant second at $8 to $10 per MWh …. Renewable energy sources like wind and solar are largely dependent on these subsidies, which have been ongoing for 30 years with no end in sight.”

But even generous subsidies often aren’t enough to ensure financial viability. Rent-enabled malinvestments like these crowd out genuinely productive capital formation. Those lost opportunities span the economy and are not limited to power plants that might otherwise have used fossil fuels.

Despite billions of dollars in “green energy” subsidies, bankruptcy has been all too common among wind and solar firms. That financial instability demonstrates the uneconomic nature of many wind and solar investments. Bankruptcy pleadings represent yet another way investors are insulated against wind and solar losses.

Subsidized Off-Hour (Wasted) Output

This almost deserves a sixth circle, except that it’s not about dormancy. Wind and solar power are sometimes available when they’re not needed, in which case the power goes unused because we lack effective power storage technology. Battery technology has a long way to go before it can overcome this problem.

When wind and solar facilities generate unused and wasted power during off-hours, their operators are nevertheless paid for that power by selling it into the grid where it goes unused. It’s another subsidy to wind and solar power producers, and one that undermines incentives for investment in batteries.

A Path To Redemption

Space-based solar power beamed to earth may become a viable alternative to terrestrial wind and solar production within a decade or so. The key advantages would be constancy and the lack of an atmospheric filter on available solar energy, producing power 13 times as efficiently as earth-bound solar panels. From the last link:

“The intermittent nature of terrestrial renewable power generation is a major concern, as other types of energy generation are needed to ensure that lights stay on during unfavorable weather. Currently, electrical grids rely either on nuclear plants or gas and coal fired power stations as a backup…. “

Construction of collection platforms in geostationary orbit will take time, of course, but development of space-based solar should be a higher priority than blanketing vast tracts of land with inefficient solar panels while putting power users at risk of outages.

No Sympathy for Malinvestment

This post identified five ways in which investments in wind and solar power create frequent and often extended periods of damnably dormant physical capital:

  • Low Utilization
  • Nondispatchable Utilization
  • Idle Transmission Infrastructure
  • Idle Backup Generators
  • Outages of All Electrified Capital

Power demand is expected to soar given the coming explosion in AI applications, and especially if the heavily-subsidized and mandated transition to EVs comes to pass. But that growth in demand will not and cannot be met by relying solely on renewable energy sources. Their variability implies substantial idle capacity, higher costs, and service interruptions. Such a massive deployment of dormant capital represents an enormous waste of resources, and the sad fact is it’s been underway for some time.

In the years ahead, the net-zero objective will motivate more bungled industrial planning as a substitute for market-driven forces. Costs will be driven higher by the imposed costs of backup capacity and/or outages. Ratepayers, taxpayers, and innocents will all share these burdens.

Creating idle, non-dispatchable physical capital is malinvestment which diminishes future economic growth. The boom in wind and solar activity began in earnest during the era of negative real interest rates. Today’s higher rates might slow the malinvestment, but they won’t bring it to an end without a substantial shift in the political landscape. Instead, taxpayers will shoulder an even greater burden, as will ratepayers whose power providers are guaranteed returns on their regulated rate bases.

A week ago I posted about electrification and particularly EV mandates, one strand of government industrial policy under which non-favored sectors of the economy must labor. This post examines a related industrial policy: manipulation of power generation by government policymakers in favor of renewable energy technologies, while fossil fuels are targeted for oblivion. These interventions are a reaction to an overwrought climate crisis narrative, but they present many obstacles, oversights and risks of their own. Chief among them is whether the power grid will be capable of meeting current and future demand for power while relying heavily on variable resources: wind and sunshine.

Like almost everything I write, this post is too long! Here is a guide to what follows. Scroll down to whatever sections might be of interest:

  • Malinvestment: Idle capital
  • Key Considerations to chew on
  • False Premises: zero CO2? Low cost?
  • Imposed Cost: what and how much?
  • Supporting Growth: with renewables?
  • Resource Constraints: they’re tight!
  • Technological Advance: patience!
  • The Presumed Elephant: CO2 costs
  • Conclusion

Malinvestment

The intermittency of wind and solar power creates a fundamental problem of physically idle capital, which leaves the economy short of its production possibilities. To clarify, capital invested in wind and solar facilities is often idle in two critical ways. First, wind and solar assets have relatively low rates of utilization because of their variability, or intermittency. Second, neither provides “dispatchable” power: it is not “on call” in any sense during those idle periods, which are not entirely predictable. Wind and solar assets therefore contribute less value to the electric grid than dispatchable sources of power having equivalent capacity and utilization.

Is “idle capital” a reasonable characterization? Consider the shipping concerns that are now experimenting with sails on cargo ships. What is the economic value of such a ship without back-up power? Can you imagine them drifting in the equatorial calms for days on end? Even light winds would slow the transport of goods significantly. Idle capital might be bad enough, but a degree of idleness allows flexibility and risk mitigation in many applications. Idle, non–dispatchable capital, however, is unproductive capital.

Likewise, solar-powered signage can underperform or fail over the course of several dark, wintry days, even with battery backup. The signage is more reliable and valuable when it is backed-up by another power source. Again, idle, non-dispatchable capital is unproductive capital.

The pursuit of net-zero carbon emissions via wind and solar power creates idle capital, which increasingly lacks adequate backup power. That should be a priority, but it’s not. This misguided effort is funded from both private investment and public subsidies, but the former is very much contingent on the latter. That’s because the flood of subsidies is what allows private investors to profit from idle capital. Rent-enabled investments like these crowd out genuinely productive capital formation, which is not limited to power plants that might otherwise use fossil fuels.

Creating idle or unemployed physical capital is malinvestment, and it diminishes future economic growth. The surge in this activity began in earnest during the era of negative real interest rates. Today, in an era of higher rates, taxpayers can expect an even greater burden, as can ratepayers whose power providers are guaranteed returns on their regulated rate bases.

Key Consideration

The forced transition to net zero will be futile, but especially if wind and solar energy are the primary focus. Keep the following in mind:

  • The demand for electricity is expected to soar, and soon! Policymakers have high hopes for EVs, and while adoption rates might fall well short of their goals, they’re doing their clumsy best to force EVs down our throats with mandates. But facilitating EV charging presents difficulties. Lionel Shriver states the obvious: “Going Electric Requires Electricity”. Reliable electricity!
  • Perhaps more impressive than prospects for EVs is the expected growth in power demand from data centers required by the explosion of artificial intelligence applications across many industries. It’s happening now! This will be magnified with the advent of artificial general intelligence (AGI).
  • Dispatchable power sources are needed to back-up unreliable wind and solar power to ensure service continuity. Maintaining backup power carries a huge “imposed cost” at the margin for wind and solar. At present, that would entail CO2 emissions, violating the net zero dictum.
  • Perhaps worse than the cost of backup power would be the cost borne by users under the complete elimination of certain dispatchable power sources. An imposed cost then takes the form of outages. Users are placed at risk of losing power at home, at the office and factories, at stores, in transit, and at hospitals at peak hours or under potentially dangerous circumstances like frigid or hot weather.
  • Historically, dispatchable power has allowed utilities to provide reliable electricity on-demand. Just flip the switch! This may become a thing of the past.
  • Wind and solar power are sometimes available when they’re not needed, in which case the power goes unused because we lack effective power storage technology.
  • Wind and solar power facilities operate at low rates of utilization, yet new facilities are always touted at their full nameplate capacity. Capacity factors for wind turbines averaged almost 36% in the U.S. in 2022, while solar facilities averaged only about 24%. This compared with nuclear power at almost 93%, natural gas (66%), and coal (48%). Obviously, the low capacity factors for wind and solar reflect their variable nature, rather than dispatchable responses to fluctuations in power demand.
  • Low utilization and variability are underemphasized or omitted by those promoting wind and solar plant in the media and often in discussions of public policy, and no wonder! We hear a great deal about “additions to capacity”, which overstate the actual power-generating potential by factors of three to four times. Here is a typical example.
  • Wind and solar power are far more heavily subsidized than fossil fuels. This is true in absolute terms and especially on the basis of actual power output, which reveals their overwhelmingly uneconomic nature. From the link above, here are Mitch Rolling and Isaac Orr on this point:
    • “In 2022, wind and solar generators received three and eighteen times more subsidies per MWh, respectively, than natural gas, coal, and nuclear generators combined. Solar is the clear leader, receiving anywhere from $50 to $80 per MWh over the last five years, whereas wind is a distant second at $8 to $10 per MWh …. Renewable energy sources like wind and solar are largely dependent on these subsidies, which have been ongoing for 30 years with no end in sight.”
  • The first-order burden of subsidies falls on taxpayers. The second-order burdens manifest in an unstable grid and higher power costs. But just to be clear, subsidies are paid by governments to producers or consumers to reduce the cost of activity favored by policymakers. However, the International Monetary Fund frequently cites “subsidy” figures that include staff estimates of unaddressed externalities. These are based on highly-simplified models and subject to great uncertainty, of course, especially when dollar values are assigned to categories like “climate change”. Despite what alarmists would have us believe, the extent and consequences of climate change are not settled scientific issues, let alone the dollar cost.
  • Wind and solar power are extremely land- and/or sea-intensive. For example, Casey Handmer estimates that a one-Gigawatt data center, if powered by solar panels, would need a footprint of 20,000 acres. 
  • Solar installations are associated with a significant heat island effect: “We found temperatures over a PV plant were regularly 3–4 °C warmer than wildlands at night….”
  • Wind and solar power both represent major hazards to wildlife both during and after construction.
    • In addition to the destruction of habitat both on- and offshore, turbine blades create noise, electromagnetism, and migration barriers. Wind farms have been associated with significant bird and bat fatalities. Collisions with moving blades are one thing, but changes to the winds and air pressure around turbines are also a danger to avian species.
    • There is a strong likelihood that offshore wind development is endangering whales and dolphins.
    • Solar farms present dangers to waterfowl. These creatures are tricked into diving toward what they believe to be bodies of water, only to crash into the panels.
  • The production of wind and solar equipment requires the intensive use of scarce resources, including environmentally-sensitive materials. Extracting these materials often requires the excavation of massive amounts of rock subject to extensive processing. Mining and processing rely heavily on diesel fuel. Net zero? No.
  • Wind and solar facilities often present major threats of toxicity at disposal, or even sooner. A recent hail storm in Texas literally destroyed a solar farm, and the smashed panels have prompted concerns not only about solar “sustainability”, but also that harsh chemicals may be leaking into the local environment.
  • The transmission of power is costly, but that cost is magnified by the broad spatial distribution of wind and solar generating units. Transmission from offshore facilities is particularly complex. And high voltage lines run into tremendous local opposition and regulatory scrutiny.
  • When wind turbines and solar panels are idle, so are the transmission facilities needed to reach them. Thus, low utilization and the variability of those units drives up the capital needed for power and power transmission.
  • There is also an acute shortage of transformers, which presents a major bottleneck to grid development and stability.
  • While zero carbon is the ostensible goal, zero carbon nuclear power has been neglected by our industrial planners. That neglect plays off exaggerated fears about safety. Fortunately, there is a growing realization that nuclear power may be surest way to carbon reductions while meeting growth in power demand. In fact, new data centers will go off-grid with their own modular reactors.
  • At the Shriver link, he notes the smothering nature of power regulation, which obstructs the objective of providing reliable power and any hope of achieving net zero.
  • The Biden administration has resisted the substitution of low CO2 emitting power sources for high CO2 emitting sources. For example, natural gas is more energy efficient in a variety of applications than other fuel sources. Yet policymakers seem determined to discourage the production and use of natural gas.

False Premises

Wind and solar energy are touted by the federal government as zero carbon and low-cost technologies, but both claims are false. Extracting the needed resources, fabricating, installing, connecting, and ultimately disposing of these facilities is high in carbon emissions.

The claim that wind and solar have a cost advantage over traditional power sources is based on misleading comparisons. First, putting claims about the cost of carbon aside, it goes without saying that the cost of replacing already operational coal or natural gas generating capacity with new wind and solar facilities is greater than doing nothing.

The hope among net zero advocates is that existing fossil fuel generating plant can be decommissioned as more renewables come on-line. Again, this thinking ignores the variable nature of renewable power. Dispatchable backup power is required to reliably meet power demand. Otherwise, fluctuating power supplies undermine the economy’s productive capacity, leading to declines in output, income, health, and well being. That is costly, but so is maintaining and adding back-up capacity. Costs of wind and solar should account for this necessity. It implies that wind and solar generating units carry a high cost at the margin.

Imposed Costs

A “grid report card” from the Mackinac Center for Public Policy notes the conceptual flaw in comparing the levelized cost (à la Lazard) of a variable resource with one capable of steady and dispatchable performance. From the report, here is the crux of the imposed-cost problem:

“… the more renewable generation facilities you build, the more it costs the system to make up for their variability, and the less value they provide to electricity markets.”

A committment to variable wind and solar power along with back-up capacity also implies that some capital will be idle regardless of wind and solar conditions. This is part of the imposed cost of wind and solar built into the accounting below. But while back-up power facilities will have idle periods, it is dispatchable and serves an insurance function, so it has value even when idle in preserving the stability of the grid. For that matter, sole reliance on dispatchable power sources requires excess capacity to serve an insurance function of a similar kind.

The Mackinac report card uses estimates of imposed cost from an Institute for Energy Research to construct the following comparison (expand the view or try clicking the image for a better view):

The figures shown in this table are somewhat dated, but the Mackinac authors use updated costs for Michigan from the Center of the American Experiment. These are shown below in terms of average costs per MWh through 2050, but the labels require some additional explanation.

The two bars on the left show costs for existing coal ($33/MWh) and gas-powered ($22) plants. The third and fourth bars are for new wind ($180) and solar ($278) installations. The fifth and sixth bars are for new nuclear reactors (a light water reactor ($74) and a small modular reactor($185)). Finally, the last two bars are for a new coal plant ($106) and a natural gas plant ($64), both with carbon capture and storage (CCS). It’s no surprise that existing coal and gas facilities are the most cost effective. Natural gas is by far the least costly of the new installations, followed by the light water reactor and coal.

The Mackinac “report card” is instructive in several ways. It provides a detailed analysis of different types of power generation across five dimensions, including reliability, cost, cleanliness, and market feasibility (the latter because some types of power (hydro, geothermal) have geographic limits. Natural gas comes out the clear winner on the report card because it is plentiful, energy dense, dispatchable, clean burning, and low-cost.

Supporting Growth

Growth in the demand for power cannot be met with variable resources without dispatchable backup or intolerable service interruptions. Unreliable power would seriously undermine the case for EVs, which is already tenuous at best. Data centers and other large users will go off-grid before they stand for it. This would represent a flat-out market rejection of renewable investments, ESGs be damned!

Casey Handmer makes some interesting projections of the power requirements of data centers supporting not just AI, but AGI, which he discusses in “How To Feed the AIs”. Here is his darkly humorous closing paragraph, predicated on meeting power demands from AGI via solar:

“It seems that AGI will create an irresistibly strong economic forcing function to pave the entire world with solar panels – including the oceans. We should probably think about how we want this to play out. At current rates of progress, we have about 20 years before paving is complete.”

Resource Constraints

Efforts to force a transition to wind and solar power will lead to more dramatic cost disadvantages than shown in the Mackinac report. By “forcing” a transition, I mean aggressive policies of mandates and subsidies favoring these renewables. These policies would effectuate a gross misallocation of resources. Many of the commodities needed to fabricate the components of wind and solar installations are already quite scarce, particularly on the domestic U.S. front. Inflating the demand for these commodities will result in shortages and escalating costs, magnifying the disadvantages of wind and solar power in real economic terms.

To put a finer point on the infeasibility of the net zero effort, Simon P. Michaux produced a comparative analysis in 2022 of the existing power mix versus a hypothetical power mix of renewable energy sources performing an equal amount of work, but at net-zero carbon emissions (the link is a PowerPoint summary). In the renewable energy scenario, he calculated the total quantities of various resources needed to achieve the objective over one generation of the “new” grid (to last 20 -30 years). He then calculated the numbers of years of mining or extraction needed to produce those quantities based on 2019 rates of production. Take a look at the results in the right-most column:

Those are sobering numbers. Granted, they are based on 2019 wind and solar technology. However, it’s clear that phasing out fossil fuels using today’s wind and solar technology would be out of the question within the lifetime of anyone currently living on the planet. Michaux seems to have a talent for understatement:

“Current thinking has seriously underestimated the scale of the task ahead.”

He also emphasizes the upward price pressure we’re likely to witness in the years ahead across a range of commodities.

Technological Breakthroughs

Michaux’s analysis assumes static technology, but there may come a time in the not-too-distant future when advances in wind and solar power and battery storage allow them to compete with hydrocarbons and nuclear power on a true economic basis. The best way to enable real energy breakthroughs is through market-driven economic growth. Energy production and growth is hampered, however, when governments strong-arm taxpayers, electricity buyers, and traditional energy producers while rewarding renewable developers with subsidies.

We know that improvements will come across a range of technologies. We’ve already seen reductions in the costs of solar panels themselves. Battery technology has a long way to go, but it has improved and might some day be capable of substantial smoothing in the delivery of renewable power. Collection of solar power in space is another possibility, as the feasibility of beaming power to earth has been demonstrated. This solution might also have advantages in terms of transmission depending on the locations and dispersion of collection points on earth, and it would certainly be less land intensive than solar power is today. Carbon capture and carbon conversion are advancing technologies, making net zero a more feasible possibility for traditional sources of power. Nuclear power is zero carbon, but like almost everything else, constructing plants is not. Nevertheless, fission reactors have made great strides in terms of safety and efficiency. Nuclear fusion development is still in its infancy, but there have been notable advances of late.

Some or all of these technologies will experience breakthroughs that could lead to a true, zero-carbon energy future. The timeline is highly uncertain, but it’s likely to be faster than anything like the estimates in Michaux’s analysis. Who knows? Perhaps AI will help lead us to the answers.

A Presumed Elephant

This post and my previous post have emphasized two glaring instances of government failure on their own terms: a headlong plunge into unreliable renewable energy, and forced electrification done prematurely and wrong. Some would protest that I left the veritable “elephant in the room”: the presumed external or spillover costs associated with CO2 emissions from burning fossil fuels. Renewables and electrification are both intended to prevent those costs.

External costs were not ignored, of course. Externalities were discussed explicitly in several different contexts such as the mining of new materials, EV tire wear, the substitution of “cleaner” fuels for others, toxicity at disposal, and the exaggerated reductions in CO2 from EVs when the “long tailpipe” problem is ignored. However, I noted explicitly that estimates of unaddressed externalities are often highly speculative and uncertain, and especially the costs of CO2 emissions. They should not be included in comparisons of subsidies.

Therefore, the costs of various power generating technologies shown above do not account for estimates of externalities. If you’re inclined, other SCC posts on the CO2 “elephant” can be found here.

Conclusion

Power demand is expected to soar given the coming explosion in AI applications, and especially if the heavily-subsidized and mandated transition to EVs comes to pass. But that growth in demand will not and cannot be met by relying on renewable energy sources. Their variability implies substantial idle capacity, higher costs, and service interruptions. Such a massive deployment of idle capital would represents an enormous waste of resources, but the sad fact is it’s been underway for some time.

In the years ahead, the net-zero objective will prove representative of a bumbling effort at industrial planning. Costs will be driven higher, including the cost inflicted by outages and environmental damage. Ratepayers, taxpayers, and innocents will share these burdens. Travis Fisher is spot on when he says the grid is becoming a “dangerous liability” thanks to wounds inflicted by subsidies, regulations, and mandates.

As Charles Glasser put it on Instapundit:

“The National Electrical Grid is teetering on collapse. The shift away from full-time available power (like fossil fuels, LNG, etc.) to so-called ‘green’ sources has deeply impacted reliability.”

“Also, as more whale-killing off-shore wind farms are planned, the Biden administration forgot to plan for the thousands of miles of transmission lines that will be needed. And in a perfect example of leftist autophagy, there is considerable opposition from enviro-groups who will tie up the construction of wind farms and transmission lines in court for decades.”

Meanwhile, better alternatives to wind and solar have been routinely discouraged. The substantial reductions in carbon emissions achieved in the U.S. over the past 15 years were caused primarily by the substitution of natural gas for coal in power generation. Much more of that is possible. The Biden Administration, however, wishes to prevent that substitution in favor of greater reliance on high-cost, unreliable renewables. And the Administration wishes to do so without adequately backing up those variable power sources with dispatchable capacity. Likewise, nuclear power has been shunted aside, despite its safety, low risk, and dispatchability. However, there are signs of progress in attitudes toward bringing more nuclear power on-line.

Industrial policy usually meets with failure, and net zero via wind and solar power will be no exception. Like forced electrification, unreliable power fails on its own terms. Net zero ain’t gonna happen any time soon, and not even by 2050. That is, it won’t happen unless net zero is faked through mechanisms like fraudulent carbon credits (and there might not be adequate faking capacity for that!). Full-scale net-zero investment in wind and solar power, battery capacity, and incremental transmission facilities will drive the cost of power upward, undermining economic growth. Finally, wind and solar are not the environmental panacea so often promised. Quite the contrary: mining of the necessary minerals, component fabrication, installation, and even operation all have negative environmental impacts. Disposal at the end of their useful lives might be even worse. And the presumed environmental gains … reduced atmospheric carbon concentrations and lower temperatures, are more scare story than science.

Postscript: here’s where climate alarmism has left us, and this is from a candidate for the U.S. Senate (she deleted the tweet after an avalanche of well-deserved ridicule):

Investments in “green energy” create jobs, just like any other form of investment in physical assets. We’re told, however, that the transition to renewable energy sources will create a veritable jobs bonanza! Apparently, this is believed to be a great selling point for everyone to get behind. Sure, promoting job creation is always popular with politicians, and it is very popular with private actors seeking to win public funding of one kind or another.

The heavy emphasis on jobs creation brings to mind an old Milton Friedman story about a visit to China during which dignitaries brought him to a construction site, no doubt thinking he’d be impressed with their progressive investments in infrastructure. At the site, Friedman noticed workers digging a large trench or arroyo with shovels. When he asked why bulldozers or backhoes weren’t used, he was told that the jobs were too valuable. His response was something like, “Then have them use spoons!” The lesson, of course, is that merely creating jobs is not a prescription for building wealth and prosperity. But there is more at stake here than the low productivity of construction workers who lack the best tools.

There are some bad rationales for heavy investment in renewable energy sources, and I’ve addressed those at length previously. The appeal to job creation, however, is awful on simple economic grounds. It emphasizes a thing that is easily counted while ignoring massive costs that are generally untallied.

In the U.S. we have a huge base of productive capital that meets our energy needs, the bulk of which is built to utilize fossil fuels. That plant constitutes wealth to society, and not just to those with an ownership interest. Dispatchable power is available to the public at a rate below that at which they value the power. That ability to deliver consumer surplus on demand is a major aspect qualifying power capacity as societal wealth. The push for renewables, if wholly successful, would make the existing base of generating capacity redundant. There is no doubt that the ultimate goal of renewable energy advocates is to destroy existing capacity reliant on fossil fuels. They simply have not come to grips with the reality that it meets energy needs far more efficiently than intermittent renewables like wind and solar power. In spirit, the effort bears a strong similarity to destroying bulldozers to replace them with shovels, or spoons!

Recently, Michael Munger discussed the mistaken notion that renewable investments are justified based on job creation. He noted that with a coincident dismantling of the existing base of power generation, it amounts to exactly what Frederic Bastiat called the broken window fallacy, which insists that breaking windows is a great way to keep glaziers fully employed. There are many examples and variations on this idea, including so-called “planned obsolescence”.

Bastiat poked fun at an elite French government official who had marveled at the economic gains reaped in England with the rebuilding of London following the “Great Fire” of 1666. Bastiat engaged in some satire by suggesting that France could greatly benefit from burning Paris to the ground. But his point was serious: we often hear that reconstruction provides a silver lining for workers following hurricanes or other disasters. Fair enough: rebuild we must. The Keynesians among us would say it works out well for workers who are otherwise unemployed. Disasters destroy wealth, however, and often lives, not to mention opportunities for incremental wealth creation that are lost forever. The reconstruction jobs are not “good news”!

Unfortunately, people get carried away with broken windows arguments, using them to justify their own pet projects. The addition of new competing products and technologies is unquestionably healthy, but not when one side enlists the state as a partner in destroying viable incumbents and existing public or private wealth. For that matter, the state and its allies seem intent on destroying invested physical capital even before it’s services can come on line… if it’s viewed as the “wrong” kind of capital.

The costs of a transition to renewables is massive. The “big ask” for green energy involves not just taxpayer support for the build and usage, with all the inefficiencies endemic to taxation and market interventions. So-called green energy also entails huge environmental costs, and it calls for the wholesale destruction of an embedded industry. That means decommissioning invested assets having many years of useful life. And that goes for physical plant all the way from the wellhead to final use, including the destruction of stoves, cars, and other machines too numerous to mention. Those machines, by the way, still account for roughly 80% of our power use.

I leave you with part of Munger’s closing:

“Once you are duped into believing destruction is productive, almost everything that a rational public policy would label as a cost becomes, by some judo move of seraphic intuition, a benefit. … The problem is that jobs are not wealth. Wealth is access to the goods, products, and services that make our lives better. It is true that ‘studies show’ that wiping out all our productive wealth based on fossil fuels … would create jobs. Those ‘studies’ are among the best arguments against doing anything of the sort.”

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.

Renewable Power Gains, Costs, and Fantasies

“Modern” renewable energy sources made large gains in providing for global energy consumption over the ten years from 2009-19, according to a recent report, but that “headline” is highly misleading. So is a separate report on the costs of solar and wind power, which claims those sources are now cheaper than any fossil fuel. The underlying facts will receive little critical examination by a hopelessly naive press, nor among analysts with more technical wherewithal. Of course, “green” activists will go on using misinformation like this to have their way with policy makers.

Extinguishing Dung Fires

The “Renewables Global Status Report” was published in mid-June by an organization called REN21: Renewables Now. Francis Menton has a good discussion of the report on his blog, The Manhattan Contrarian. The big finding is a large increase in the global use of “modern” renewable energy sources, from 8.7% of total consumption in 2009 to 11.2% in 2019. The “modern” qualifier is critical: it distinguishes renewables that made gains from those that might be considered antiquated, like dung chips, the burning of which is an energy staple in many underdeveloped parts of the world. In fact, the share of those “non-modern renewables” declined from 11.0% to 8.7%, almost fully accounting for the displacement caused by “modern renewables”. The share of fossil fuels was almost unchanged, down from 80.3% in 2009 to 80.2% in 2019. Whatever the benefits of wind, solar, and other modern green power sources, they did not make much headway in displacing reliable fossil fuel energy.

I certainly can’t argue that replacing dung power with wind, solar, or hydro is a bad thing (but there are more sophisticated ways of converting dung to energy than open flame). However, I contend that replacing open dung fires with fossil-fuel or nuclear capacity would be better than renewables from both a cost and an environmental perspective. Be that as it may, the adoption of “modern renewables” over the ten-year period was not at the expense of fossil fuels, as might be expected if the latter was at a cost disadvantage, and remember that renewables were already given an edge via intense government efforts to subsidize and even require the use of wind and solar power.

The near-term limits on our ability to substitute renewables for fossil fuels should be fairly obvious. For one thing, renewable power is intermittent, so it cannot be relied upon for baseload generation. The chart at the top of this post demonstrates this reality, though the chart is “optimistic” in the sense that planners have to consider worst-case intermittency, not merely average production by time-of-day. Reliable power sources must be maintained in order to prevent the kinds of disasters like we saw in Texas last winter when demand spiked and output from renewables plunged. This is an area of considerable denialism: a search on “intermittent renewables” gets you an unending list of rosy assessments of energy storage technologies, and very little realistic commentary on today’s needs for meeting base-load or weather-induced demands.

While renewables account for about 29% of global electricity generation, there is another limit on adoption: certain jobs just can’t be done with renewables short of major advances in battery technology. As Menton says:

“Steel mills and tractor trailer trucks and airplanes powered by solar panels? Not happening. … I think these people really believe that if governments will just do the right thing and require airplanes to run on solar panels, then it will promptly happen.”

Cost and Intermittency

Again, we’d expect to see more rapid conversion to renewable energy, at least in compatible applications, as the cost of renewables drops relative to fossil fuels. And major components of their costs have indeed dropped, so much so that the U.S. Energy Information Administration (EIA) now says they are cheaper than fossil fuels in terms of the “levelized cost” of new electric generating capacity. That’s the average cost per megawatt-hour produced over the life of a new installation. The EIA’s calculations are distorted on at least two counts, however, as Willis Eschenbach ably explains here.

The EIA’s cost figures reflect a “capacity factor” that adjusts the megawatts produced to presumed “real world” conditions. It’s more like a utilization adjustment made necessary by a variety of realities (intermittency as well as other technical imperfections) that cause output to run lower than the maximum under ideal conditions. Eschenbach reports that the factors applied by the EIA for solar and wind, at 30% and 41%, respectively, are overstated drastically, which reduces their cost estimates by overstating output. For solar, he cites a more realistic value of 14%, which would more than double the levelized cost of solar. For wind, he quotes a figure of 30%, which would increase the cost of wind power by more than a third. That puts the cost of those renewables well above that of a “combined-cycle gas” plant, which uses exhaust from gas turbines to generate additional power via steam.

The true costs of renewables are likely much higher than nuclear power as well, based on earlier comparisons of nuclear to combined-cycle gas. The EIA does not report a cost for nuclear power, however, because the report is for new capacity, and no additions of nuclear capacity are expected.

The Cost of Back-Up Capacity

Eschenbach notes a second major problem with the EIA cost comparisons. As discussed above, the intermittency of solar and wind power means that their deployment cannot provide for base loads. Other “dispatchable” power technologies, on which production can be ramped up or down at discretion, must be available to meet power needs when renewables are off-line, as is frequently the case. The more we attempt to rely on renewables, the more significant the intermittency problem becomes, as Germany, Texas, and California are discovering.

How to account for the extra cost of dispatchable power required to smooth production or meet peak demand? Renewables are simply incapable of doing so reliably, and back-up capacity ain’t free! Meeting demand at all times requires equivalent dispatchable capacity in the power mix. It requires not just dispatchable baseload capacity, but surge capacity! Meeting long-term growth in demand with renewables implies that new back-up capacity is required as well, and the levelized cost should reflect it. After all, those costs won’t be saved by virtue of adding renewable capacity, unless you plan on blackouts. Thus, the EIA’s levelized cost comparisons of wind, solar and fossil fuel electricity generation are completely phony.

Conclusion

Growth in wind and solar power increased their contribution to global energy needs to more than 11% in 2019, but their gains over the previous ten years came largely at the expense of more “primitive” renewable energy sources, not fossil fuels. And despite impressive declines in the installation costs of wind and solar power, and despite low variable costs, the economics of power generation still favors fossil fuels rather substantially. In popular discussions, this point is often obscured by the heavy subsidies granted to renewables. 

In truth, the “name-plate” capacities of wind and solar installations far exceed typical output, so installation costs are spread over less output than is widely believed. Furthermore, the intermittency of production from these renewable sources means that back-up capacity is still required, almost always from plants fired by fossil fuels. Properly considered, this represents a significant incremental cost of renewable power sources, but it is one that is routinely ignored by environmentalists and even in official reports. It’s also worth noting that “modern” renewables carry significant external costs to the environment both during the useful life of plant and at disposal (and see here). It’s tempting to say all these distortions and omissions are deliberate contributions to the propaganda in favor of government mandates for renewables.
