The current protests on college campuses across the nation bring into focus differing opinions on the limits of free speech and assembly. Particular questions seem to defy resolution. Nevertheless, there is some misunderstanding regarding the settled breadth of the First Amendment.
The protestors have acted as if they have constitutional carte blanche to gather anywhere to say anything in opposition to Israel and its war against Hamas terrorists; a subset thinks this encompasses “occupation” of any space for any duration; a still smaller subset believes this includes a right to condemn Jews, all Jews.
I strongly doubt, however, that many of the protestors truly believe their constitutional protections extend to intimidation and bullying of Jewish students attempting to go about their business on campus (scroll to a few of the articles here), destruction of property, or the use of “fighting words”, or physical attacks on Jews or other “oppressors”.
It’s well known that the Constitution does not protect “fighting words”, including threats.Furthermore,Eugene Volokh explains that there is no constitutional right to “occupy” a college campus, either public or private.
Of course, private schools are not legally bound to respect free speech or assembly rights. They can regulate activity on their private campuses in any way they see fit. Some explicitly abide the same rights as public universities, which seems reasonable for any institution dedicated to the free spirit of inquiry.
Volokh, however, cites Supreme Court precedents in which a majority held that government can prohibit camping in certain parks, for example, and that public colleges and universities can impose restrictions on campus activities:
“There is no First Amendment right to camp out in any university, public or private. Indeed, there is no First Amendment right to camp out even in public parks (see Clark v. CCNV (1984)), and the government’s power to limit the use of property used for a public university is even greater than its power as to parks (Widmar v. Vincent (1981)):
“‘A university differs in significant respects for public forums such as streets or parks or even municipal theaters. A university’s mission is education, and decisions of this Court have never denied a university’s authority to impose reasonable regulations compatible with that mission upon the use of its campus and facilities. We have not held, for example, that a campus must make all of its facilities equally available to students and nonstudents alike, or that a university must grant free access to all of its grounds or buildings.’
“Likewise, if UC Berkeley had held a law student party in the law school building rather than at Dean Chemerinsky’s house, it could have stopped students from using the party as an occasion to orate to the audience (especially with their own sound amplification devices, which the student brought to Chemerinsky’s house). See Spears v. Arizona Bd. of Regents (D. Ariz. 2019)(upholding public university’s right to stop people from speaking with sound amplification at an on-campus book fair).“
Volokh also notes, however, that public universities cannot restrict mere “offensive” expression, which would include certain antisemitic statements or evenswastikas (for example), as long as the expression falls short of “fighting words” or explicit threats. Do calls for the “extermination of Jews” qualify as fighting words? That deserves a resounding yes. It’s clearly hate speech, and it’s exactly the sort of expression that might be deemed so offensive to counterprotestors (for example) as to constitute an immediate threat to public order.
Does the meaning of “fighting words” include such chants as “From the river to the sea…”? Some say that depends on the speaker, but that can’t provide a sound basis of distinction. It is clearly associated with calls to eliminate the state of Israel. Some believe it also implies the genocide of Jews in Israel, and Jews can’t be blamed for finding it threatening. Okay, how about “Intifada”? I doubt all of the students involved in the current protests understand the genocidal implications of these words. The agitators understand them well enough.
This is a grey area in our understanding of the First Amendment. The “River to the Sea” chant, and Intifada, seemlike fighting words to me, but they might not qualify as direct threats to anyone on campus. By comparison, the swastika is “just” a party emblem, whatever policies it stands for, and apparently the Court did not deem it a direct threat to anyone in Skokie, Illinois. The legal distinctions here feel inadequate. Still, we say the “mere” expression of offensive ideas or symbols is protected speech, provided that it does not directly threaten harm to any party.
Many libertarians, with whom I usually agree, urge tolerance of the protests and encampments, including at least cautious tolerance of the protests. The Foundation for Individual Rights and Expression (FIRE) has strenuously objected to the actions of police in Austin, Texas in dispersing demonstrators at the University of Texas. Alex Tabarrak has reposted a tweet or two apparently critical of the government’s response to protestors in Texas and at Emory University in Atlanta, though it should be noted that the economics professor who was taken down and handcuffed on video had actually hit a police officer. Michael Munger, in a variation of his “worst enemy test” of government power, says that giving campus authorities “the power to crush us, at their discretion” is probably a bad idea. But they have that power if they choose to exercise it, for better or worse. (By “us”, I don’t think Munger intended to take sides).
I’m highly skeptical of the motives and incentives of some of the “occupiers” of campus spaces, not to mention their status as students. More importantly, there is ample evidence that “fighting words” and threats against Jews have been used by many of the protesters. This violates the codes of conduct at many schools, and should not only be censured, but any student identified as guilty of this sort of hate speech should be expelled, not merely suspended. There should be severe consequences for professors choosing to participate in these protests as well.
This behavior should have long-term consequences, and that is happening at some schools. I saw the following quote from P.J. O’Rourke on Instapundit, which seems appropriate here:
“There’s only one basic human right, the right to do as you damn well please. And with it comes the only basic human duty, the duty to take the consequences.”
The kids are wearing masks for a reason, and it ain’t Covid! Now, the protestors’ demands include “amnesty” for their participation in the protests. That shouldn’t play well if you’re provably guilty of calling for the extermination of a race of people. But here’s the thing: certain institutions like Columbia University have allowed the aberrant behavior to go on with little challenge, showing that the real limits to free speech and assembly are whatever acquiescent campus administrators are willing to put up with.
Removing these encampments is more than justified on constitutional grounds at any school, public or private. The arrest of some of the more intransigent elements among the protesters may be well justified. Insulting hate speech is one thing, but eliminationist hate speech constitutes fighting words and should not be tolerated. Of course, forcibly removing the encampments is risky in terms of public safety because some of the protestors will physically challenge the police. Comparatively innocent (though naive) students might get caught up in a conflict with law enforcement, but ignorance is no defense. They should not be there. Those risks must be taken to end the “hate encampments”, which are a direct threat to the rights of others wishing only to go about their business.
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 producewhen 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!
QuantifyingInfernal 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 subsidiesoften 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.
SubsidizedOff-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.
The Fed’s “higher for longer” path for short-term interest rates lingers on, and so does inflation in excess of the Fed’s 2% target. No one should be surprised that rate cuts aren’t yet on the table, but the markets freaked out a little with the release of the February CPI numbers last week, which were higher than expected. For now, it only means the Fed will remain patient with the degree of monetary restraint already achieved.
Dashed Hopes
As I’ve said before, there was little reason for the market to have expected the Fed to cut rates aggressively this year. Just a couple of months ago, the market expected as many as six quarter-point cuts in the Fed’s target for the federal funds rate. The only rationale for that reaction would have been faster disinflation or the possibility of an economic “hard landing”. A downturn is not out of the question, especially if the Fed feels compelled to raise its rate target again in an effort to stem a resurgence in inflation. Maybe some traders felt the Fed would act politically, cutting rates aggressively as the presidential election approaches. Not yet anyway, and it seems highly unlikely.
There is no assurance that the Fed can succeed in engineering a “soft landing”, i.e., disinflation to its 2% goal without a recession. No one can claim any certainty on that point — it’s too early to call, though the odds have improved somewhat. As Scott Sumner succinctly puts it, a soft landing basically depends on whether the Fed can disinflate gradually enough.
It’s a Demand-Side Inflation
I’d like to focus a little more on Sumner’s perspective on Fed policy because it has important implications for the outlook. Sumner is a so-called market monetarist and a leading proponent of nominal GDP level targeting by the Fed. He takes issue with those ascribing the worst of the pandemic inflation to supply shocks. There’s no question that disruptions occurred on the supply side, but the Fed did more than accommodate those shocks in attempting to minimize their impact on real output and jobs. In fact, it can fairly be said that a Fed / Treasury collaboration managed to execute the biggest “helicopter drop” of money in the history of the world, by far!
That “helicopter drop” consisted of pandemic relief payments, a fiscal maneuver amounting to a gigantic monetary expansion and stimulus to demand. The profligacy has continued on the fiscal side since then, with annual deficits well in excess of $1 trillion and no end in sight. This reflects government demand against which the Fed can’t easily act to countervail, making the job of achieving a soft landing that much more difficult.
The Treasury, however, is finding a more limited appetite among investors for the flood of bonds it must regularly sell to fund the deficit. Recent increases in long-term Treasury rates reflect these large funding needs as well as the “higher-for-longer” outlook for short-term rates, inflation expectations, and of course better perceived investment alternatives.
The Nominal GDP Proof
There should be no controversy that inflation is a demand-side problem. As Summer says, supply shocks tend to reverse themselves over time, and that was largely the case as the pandemic wore on in 2021. Furthermore, advances in both real and nominal GDP have continued since then. The difference between the two is inflation, which again, has remained above the Fed’s target.
So let’s see… output and prices both growing? That combination of gains demonstrates that demand has been the primary driver of inflation for three-plus years. Restrictive monetary policy is the right prescription for taming excessive demand growth and inflation.
Here’s Sumner from early March (emphasis his), where he references flexible average inflation targeting (FAIT), a policy the Fed claims to be following, and nominal GDP level targeting (NGDPLT):
“Over the past 4 years, the PCE price index is up 16.7%. Under FAIT it should have risen by 8.2% (i.e., 2%/year). Thus we’ve had roughly 8.5% excess inflation (a bit less due to compounding.)
Aggregate demand (NGDP) is up by 27.6%. Under FAIT targeting (which is similar to NGDPLT) it should have been up by about 17% (i.e., 4%/year). So we’ve had a bit less than 10.6% extra demand growth. That explains all of the extra inflation.”
Is Money “Tight”?
The Fed got around to tightening policy in the spring of 2022, but that doesn’t necessarily mean that policy ever advanced to the “tight” stage. Sumner has been vocal in asserting that the Fed’s policy hasn’t looked especially restrictive. Money growth feeds demand and ultimately translates into nominal GDP growth (aggregate demand). The latter is growing too rapidly to bring inflation into line with the 2% target. But wait! Money growth has been moderately negative since the Fed began tightening. How does that square with Sumner’s view?
In fact, the M2 money supply is still approximately 35% greater than at the start of the pandemic. There’s still a lot of M2 sloshing around out there, and the Fed’s portfolio of securities acquired during the pandemic via “quantitative easing” remains quite large ($7.5 trillion). Does this sound like tight money?
Again, Sumner would say that with nominal GDP ripping ahead at 5.7%, the Fed can’t be credibly targeting 2% inflation given an allowance for real GDP growth at trend of around 1.8% (or even somewhat greater than that). It’s an even bigger stretch if M2 velocity (V — turnover) continues to rebound with higher interest rates.
Wage growth also exceeds a level consistent with the Fed’s target. The chart below shows the gap between price inflation and wage inflation that left real wages well below pre-pandemic levels. Since early 2023, wages have made up part of that decline, but stubborn wage inflation can impede progress against price inflation.
Just Tight Enough?
Despite Sumner’s doubts, there are arguments to be made that Fed policy qualifies as restrictive. Even moderate declines in liquidity can come as a shock to markets grown accustomed to torrents from the money supply firehose. And to the extent that inflation expectations have declined, real interest rates may be higher now than they were in early November. In any case, it’s clear the market was disappointed in the higher-than-expected CPI, and traders were not greatly assuaged by the moderate report on the PPI that followed.
However, the Fed pays closest attention to another price index: the core deflator for personal consumption expenditures (PCE). Inflation by this measure is trending much closer to the Fed’s target (see the second chart below). Still, from the viewpoint of traders, many of whom, not long ago, expected six rate cuts this year, the reality of “higher for longer” is a huge disappointment.
Danger Lurks
As I noted, many believe the odds of a soft landing have improved. However, the now-apparent “stickiness” of inflation and the knowledge that the Fed will standby or possibly hike rates again has rekindled fears that the economy could turn south before the Fed elects to cut its short-term interest rate target. That might surprise Sumner in the absence of more tightening, as his arguments are partly rooted in the continuing strength of aggregate demand and nominal GDP growth.
There’s a fair degree of consensus that the labor market remains strong, which underscores Sumner’s doubts as to the actual tenor of monetary policy. The March employment numbers were deceptive, however. The gain in civilian employment was just shy of 500,000, but that gain was entirely in part-time employment. Full-time employment actually declined slightly. In fact, the same is true over the prior 12 months. And over that period, the number of multiple jobholders increased by more than total employment. Increasing reliance on part-time work and multiple jobs is a sign of stress on household budgets and that firms may be reluctant to commit to full-time hires. From the establishment survey, the gain in nonfarm employment was dominated once again by government and health care. These numbers hardly support the notion that the economy is on solid footing.
There are other signs of stress: credit card delinquencies hit an all-time high in February. High interest rates are taking a toll on households and business borrowers. Retail sales were stronger than expected in March, but excess savings accumulated during the pandemic were nearly depleted as of February, so it’s not clear how long the spending can last. And while the index of leading indicators inched up in February, it was the first gain in two years and the index has shown year/over-year declines over that entire two-year period.
Conclusion
It feels a little hollow for me to list a series of economic red flags, having done so a few times over the past year or so. The risks of a hard landing are there, to be sure. The behavior of the core PCE deflator over the next few months will have much more influence on the Fed policy, as would any dramatic changes in the real economy. The “data dependence” of policy is almost a cliche at this point. The Fed will stand pat for now, and I doubt the Fed will raise its rate target without a dramatic upside surprise on the core deflator. Likewise, any downward rate moves won’t be forthcoming without more softening in the core deflator toward 2% or definitive signs of a recession. So rate cuts aren’t likely for some months to come.
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….”
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.
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.
“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):
In advanced civilizations the period loosely called Alexandrian is usually associated with flexible morals, perfunctory religion, populist standards and cosmopolitan tastes, feminism, exotic cults, and the rapid turnover of high and low fads---in short, a falling away (which is all that decadence means) from the strictness of traditional rules, embodied in character and inforced from within. -- Jacques Barzun
