In the Wake of the News

RDD&D - ORIGINAL CONTENT

The path to new technology consists of research, development, demonstration and finally deployment. Research and development frequently continue in an effort to improve the technology. However, at some point, the technology is determined to be far enough advanced to proceed to demonstration; and, upon successful demonstration, to deployment.

Wind and solar technology have advanced through demonstration to deployment. However, it is important to understand what has been demonstrated and what is being deployed. Wind and solar have demonstrated that they are capable of generating electricity when the wind is blowing and the sun is shining. They have also demonstrated that they cannot generate electricity in the absence of wind and/or sun.

Both technologies are being deployed as “source of opportunity” generators and are provided with conventional generation backup for periods when they cannot generate.

Several jurisdictions in the US and Europe have also attempted to demonstrate that wind and solar could replace conventional generation. These attempts have been unsuccessful. They have clearly demonstrated that wind and solar, as intermittent generators, require full capacity backup to maintain a stable and reliable electric grid.

California and several European countries have decommissioned conventional  generation as wind and solar capacity were installed. During periods of low/no wind and solar availability, they have resorted to importing electricity from nearby states or nations. California has also resorted to rolling blackouts during periods when adequate imported electricity was unavailable.
 
The UK and Germany have also shut down conventional generation as wind and solar were installed and have relied on imported electricity during periods of low/no wind and solar availability. However, a recent fire disabled one of two undersea cables carrying electricity from France to the UK and one French nuclear generator experienced an issue and was shut down, thus limiting the ability of the UK to import electricity.

Texas decided not to decommission conventional capacity, but also not to keep some of the capacity operating at idle, ready to increase output as required. The recent polar vortex disabled so much wind and solar generation that the conventional generators operating at idle did not have sufficient capacity to supply the contemporaneous demand of the grid; and, the conventional plants which were not operating at idle were unable to come on line quickly enough to prevent grid failure for a variety of reasons.

These experiences were a clear demonstration that wind and solar cannot replace conventional generation, though they can displace its output when wind and solar conditions allow them to operate.

It remains to be demonstrated that wind and solar, combined with electricity storage, can replace conventional generation. This demonstration cannot begin until battery R&D produces battery technology that can demonstrate the ability to efficiently store and redeliver electricity over multi-day periods of low/no solar availability. The number of days of battery operation required for this demonstration to be successful would be a function of the maximum number of days of “wind drought” or “solar drought” which might occur at the generating sites. The excess wind and/or solar capacity required to recharge storage after depletion would be a function of the frequency of occurrence of low/no wind and solar days.

Until this demonstration has been completed successfully it would be irresponsible to decommission the conventional generating capacity required to supply the grid when wind and solar are unavailable. However, there will likely continue to be political and regulatory pressure to do so to limit electric rate increases resulting from maintaining redundant generating capacity.

Is the World Ready for Good News on Climate?


"Come on a time travel trip with me and our new paper just out (me along with Matt Burgess and Justin Ritchie). Let’s go back to 2005 and take a look at how the world’s top energy and climate experts envisioned the range of plausible futures for climate change to 2100, and explore how they might react to our new analysis. The future is always an unknown place, but if we are going to create desirable futures, then we need to have some way of reliably projecting where were are headed and how we might alter course if we decide that we are headed in a wrong direction.

In climate policy, expectations for the future have long been characterized as scenarios, which according to the Intergovernmental Panel on Climate Change allow us to assess “a range of plausible futures, because human development is determined by a myriad of factors including human decision making.” There are of course a very wide range of plausible scenarios for the future, defined as “a variety of future states that are considered ‘occurrable’ (could happen).”

The figure below illustrates the future as an expanding cone of possibilities — of which some are possible, plausible and probable, with some futures more preferrable than others. The notion of “business as usual” has long been considered to be where we are currently headed if we don’t change course. We implement policy to try to shape the cone of future possibilities toward more preferred outcomes." (continue reading)

Electric Transition

 

The US EIA graph below summarizes the sources and uses of energy in the US economy. The Administration has established a series of progressive goals to eliminate fossil fuel consumption in the energy economy and achieve Net Zero emissions by 2050.

 

U.S. energy consumption by source and sector 2020

 

Currently, electricity from all sources represents 12.5 quads of the total of 69.7 quads of energy consumed in the economy, or approximately 18% of total energy consumption. Net Zero would require that all uses of petroleum, natural gas and coal which result in the emission of CO2 be replaced by renewable electricity. This would specifically exclude the petroleum and natural gas consumed in the production of chemicals and plastics. Therefore, approximately 30 quads of petroleum, 30 quads of natural gas and 9 quads of coal end-use consumption would be transitioned to renewable electricity by 2050.

Assuming that the Industrial and transportation electric end uses would average three times the efficiency of the fossil fuel end uses and that the residential and commercial electric end uses would average twice the efficiency of the fossil end uses, renewable electricity generation would be required to replace not only 7 quads of fossil fuel-generated electricity but also provide approximately 7 quads to replace fossil energy consumption in the industrial sector, approximately 7 quads to replace fossil energy consumption in the transportation sector and approximately 5 quads to replace fossil energy consumption in the residential and commercial sectors of the economy.

The combined effect of these energy transitions is to approximately quadruple current electricity demand and consumption in the economy. US electric utilities currently operate approximately 850 GW of fossil-fueled electric generation capacity, which historically operates at approximately a 40% system load factor and represents an approximate 20% capacity reserve margin relative to peak demand.

US EIA uses a 45% capacity factor for wind and a 30% capacity factor for solar PV generation. Therefore, a combination of wind and solar generation would have a capacity factor similar to the grid capacity factor. However, current grid generating capacity, with the exception of wind and solar generation, is dispatchable to meet contemporaneous grid demand. Wind and solar generation require storage to render them dispatchable. The storage system design must accommodate timing differences between peak generation and peak demand, multi-day periods of low/no wind and/or solar availability and seasonal variations in capacity factor. Currently, storage systems capable of multi-day and seasonal compensation are unavailable.

The transition of the existing electric grid to renewable generation is currently being accomplished by relying on conventional generation sources to supply the grid during periods of low/no wind and/or solar availability. However, the requirement to discontinue operation of existing fossil generation capacity, combined with the increased demand and consumption which would result from the electrification of all current fossil fuel end uses in the industrial, transportation, residential and commercial sectors of the economy would require that all additional renewable generating capacity be combined with adequate storage to render the capacity dispatchable, plus the additional generation capacity necessary to recharge depleted storage while still meeting the contemporaneous demand of the grid.

Crossing (or not) the 1.5 and 2.0C thresholds


The first rule of climate chess is this.  The board is bigger than we think, and includes more than fossil fuels.”  – Jon Foley

The strategy to limit global warming is tied directly to limiting the amount of CO2 emitted into the atmosphere. Emissions targets are a centerpiece of the UNFCCC Paris Agreement.  The goal of the emissions targets is to limit global warming to well below 2, preferably 1.5 degrees Centigrade, compared to pre-industrial levels (typically the baseline period 1851-1900).  For reference, the climate has warmed in 2020 by about 1.2oC

Using the medium emissions scenario (SSP2-4.5), the IPCC AR6 constrained global mean temperature projections indicate that there is a 50% chance that the 1.5oC threshold would be crossed around 2030 and the 2oC threshold would be crossed around 2052.  There is uncertainty in the year for which the thresholds would be crossed (2026-2042 for the 1.5oC threshold and 2038-2072 for the 2oC threshold), mostly owing to the range of climate sensitivity to CO2 among different models.

This post illustrates now natural climate variability could influence the global mean surface temperature change through 2050, and hence influence the time of crossing the 1.5 and 2.0oC thresholds.  Specifically, alternative scenarios of volcanic eruptions, solar variability and internal climate variability are considered.  The risk from not realistically accounting for natural climate variability is that critical possible future climate outcomes are being discounted, potentially causing maladaptation.  Each of the scenarios presented here is arguably more plausible than the high emissions scenarios RCP8.5/SSP4-8.5 LINK.  For additional reference, see also this previous blog post."

Should Government Control Scientific Research?

 

"This is the transcript of a talk I gave to the ASME (The American Society of Mechanical Engineers) South Texas Section January 20, 2022

Federal money allows unelected bureaucrats to control scientific research. They dictate the projects, and often the outcomes. They use selective leaks to the press to embarrass anyone who tries to interfere with their control. They trade in fear and relish it. Anyone who disagrees with them is suppressing “science.”

They also use an ignorant and compliant news media, to demonize privately funded scientific research as “corrupted” by “evil” corporations.[1] Government research is “science” and privately funded research is corrupt. Using this narrative, they become the “truth,” and no contrary views are allowed.

President Eisenhower said, quote:

“The prospect of domination of the nation’s scholars by Federal employment, project allocation, and the power of money is ever present and is gravely to be regarded.”

Gas Appliance Phaseout

Achieving Net Zero GHG emissions by 2050 would require a complete phaseout of residential and commercial gas appliances, including furnaces and boilers, water heaters, ranges and ovens, laundry dryers, grills, and standby generators.

US DOE, in cooperation with the US electric utility industry, has been attempting to eliminate gas end uses for decades. Initially, this effort was based on the ludicrous fantasy that electricity magically appeared at the customers’ meters at 100% efficiency. This fantasy ignored the primary energy losses during the generation processes as well as the secondary losses, including generating plant parasitic power consumption as well as transmission and distribution losses. This approach placed gas end uses at a disadvantage since gas parasitic losses and transmission and distribution losses are far lower than those in the electric system, and gas equipment losses occur downstream of the customer meter.

This fantasy rationalization has now been replaced by the fantasy of climate change as a “crisis”, “emergency” or “existential threat". The federal government has set Net Zero as a goal to be achieved by 2050, but with no published plan to achieve the goal. The Administration has taken several steps toward a gas phaseout, including a proposed ban on gas exploration and production both offshore and on federal lands. The Administration is also pressuring lenders to refuse to finance new gas system investment. Several state governments have banned hydraulic fracturing for natural gas production. Other states have refused to approve pipeline expansions to serve growing consumer demand. One state is attempting to halt operation of an existing pipeline that serves both US and Canadian markets. Several cities have banned or announced bans on new natural gas connections.

These actions have already driven significant increases in natural gas prices and have threatened supply shortages. The situation will only get worse as supply is restricted further.

Replacing existing gas end-use appliances and equipment with electric end-use equipment would often require electric service upgrades of 100 amperes in residential dwellings and of several hundred amperes in commercial buildings. The replacement appliances and equipment would add thousands of dollars to the cost. The replacement electric appliances would also increase consumer energy bills as electricity rates increase due to the transition to renewable energy sources plus electricity storage.

The realization that gas service would become unavailable in the future would cause builders and their customers to choose all-electric construction to avoid later conversion costs. It would also cause customers faced with appliance replacement decisions to choose electric appliances to replace worn-out gas equipment. Progressive appliance and equipment replacement would increase gas costs as the existing transmission and distribution infrastructure was used to deliver less and less gas over time. It is completely predictable that these cost increases would be blamed on the suppliers, rather than on the government actions which caused the increases.

The unavailability of gas standby generation systems would increase the vulnerability of customers which require an uninterruptible power supply, such as hospitals, nursing homes, prisons, and some residential buildings including high-rise apartment and condominium complexes, to grid interruptions.

2022 Energy Predictions: Coal Decline Accelerates, Federal Funds Spur Clean Energy, Millions Of New Electric Vehicles And Chargers


"2021 was a landmark year for clean energy and climate policy, from dozens of nations pledging to phase out coal, to the most ambitious federal climate proposals in United States history, to automakers going all in on electrified transportation.

Many of these developments were forecast by policy experts who thought Democratic control of the White House and Congress, fast-falling clean energy and electrified technology prices, and the undeniable need to confront climate change by cutting emissions portended a groundswell of action.

But the outlook for 2022 is not as clear. Will China commit to phasing out new domestic coal plants? Will the U.S. Senate finally pass the Build Back Better Act (BBBA) and unlock hundreds of billions in investment? How will billions in electric vehicle (EV) and grid investments from the Infrastructure Investment and Jobs Act (IIJA) be allocated? And will growing consumer demand for clean energy drive new renewable energy, EV, and electrified appliance sales?

Five leading policy experts shared their predictions for the year ahead including coal’s accelerating decline, federal investments energizing clean energy adoption and grid expansion, and millions of EVs hitting U.S. roads to help EV chargers become a new investment class." (continue reading)

The Cost of Net Zero Electrification of the U.S.A.

 

"This article by Ken Gregory, P. Eng. is a critique of an influential report  by Thomas Tanton “Cost of Electrification: A State-by-State Analysis and Results” and provides corrected new capital cost estimates to achieve net zero emissions in the U.S.A. Estimating the increased operating costs is beyond the scope of the study.  This post provides a condensed version of the blog post previously published at Friends of Science here.


Executive Summary

Many governments have made promises to reduce greenhouse gas emissions by replacing fossil fuels with solar and wind generated electricity and to electrify the economy. A report by Thomas Tanton estimates a capital cost of US$36.4 trillion for the U.S.A. economy to meet net zero emissions using wind and solar power. This study identifies several errors in the Tanton report and provides new capital cost estimates using 2019 and 2020 hourly electricity generation data rather than using annual average conditions as was done in the Tanton report.  This study finds that the battery costs for replacing all current fossil fuel fired electricity with wind and solar generated electricity, using 2020 electricity data, is 109 times that estimated by the Tanton report. The total capital cost of electrification is herein estimated, using 2020 data, at US$433 trillion, or 20 times the U.S.A. 2019 gross domestic product. Overbuilding the solar plus wind capacity by 21% reduces overall costs by 18% by reducing battery storage costs. Allowing fossil fuels with carbon capture and storage to provide 50% of the electricity demand dramatically reduces the total costs from US$433 trillion to US$24 trillion, which is a reduction of 94.6%. Battery storage costs are highly dependent on the year’s weather and the seasonal shape of electricity demand.

 

The U.S.A. government has set a target to reduce greenhouse gas emissions from fossil fuel use and cement manufacturing to net zero economy-wide by no later than 2050. Some believe this could be achieved by replacing most fossil fuel use with non-emitting energy sources and sequestering carbon dioxide (CO2) emissions from the remaining fossil fuel use by carbon capture and storage (CCS)."

US ICE Vehicle Phaseout

We need to make green energy much cheaper.”, Bjorn Lomborg

Global policymakers appear to have adopted a uniform approach to the green energy transition – making fossil energy unavailable through supply restriction or legislative and regulatory prohibition, or more expensive through taxation. They either lack confidence in future green energy cost reductions or they lack the patience to wait for those cost reductions. Lomborg sees the need to make green energy cheaper in absolute terms, while policymakers pursue the approach of making it cheaper in relative terms by increasing the cost of conventional energy and its end uses.

The US government and some state governments are pursuing these approaches to phaseout internal combustion engine (ICE) vehicles and transition to electric vehicles (EVs) or hydrogen fueled vehicles. California plans to ban sale of ICE vehicles in 2030, while the federal government plans to ban their sale in 2035. The federal government currently pays incentives of up to $7,500 to purchasers of electric vehicles and plans to increase the incentives to up to $12,500 for vehicles produced by union labor. The federal government also intends to incentivize installation of up to 500,000 electric vehicle charging stations, with a focus on disadvantaged and underserved neighborhoods. Incentives are also planned for electric school buses and transit buses.

These mandates and incentives are deemed necessary because current electric vehicles are expensive, largely because of the cost of their batteries. Also, current EVs are range limited by their batteries, reducing their utility for other than short trips. EV owners also experience “fuel anxiety” because of the limited EV charging infrastructure.

The EV transition is also currently being impeded by concerns about battery fires, which have resulted in major vehicle recalls. Concerns regarding battery fires are also causing some jurisdictions to consider prohibiting EV charging stations in public and private parking structures and underground parking facilities in residential complexes.

There are currently light duty and medium duty EVs available in the market, though they represent only approximately 7% of passenger car sales and a lesser share of light and medium duty truck sales. Heavy duty EV trucks are just being introduced to the market and EV semi-tractors are under development. The major concern with these heavy-duty vehicles is the effect the weight of the batteries has on the gross vehicle weight (GVW) of the truck and the limitation that imposes on cargo weight.

The conversion of railroad vehicles to EV is a major challenge. EV passenger rail in highly populated areas of the country has been in use for decades. However, passenger rail power demands are much lower than for freight service. Freight locomotives in current service use electric drive motors at the wheels, but the electricity is provided by diesel generators in the locomotives. Installing overhead electric lines of sufficient current carrying capacity on the 140,000 route miles of freight rail infrastructure and converting existing locomotives with catenaries and transformers would be an extremely expensive undertaking.

Conversion of off-road vehicles, such as farm and construction equipment, to EV operation present interesting charging and utility challenges.

Where Fake Science Came From


"Journalists created the global warming scare, not real scientists. There always is a lot of incompetence and errors in science, but they slowly wash out under normal conditions. Journalists railroaded that process with global warming—imposing nihilism onto the public and scandalizing real scientist out of science.

Then they repeated the same thing with the non-solution of renewable energy. Real engineers tried to explain the fallacy of such renewable energy, but they were shoved out of the process by totalitarian journalists.

Why that happened is being revealed with the fascist overthrow of government. It's because modern methods of reality control systematically overwhelm rationality. Reality is being railroaded everywhere by the transformation of journalistic media. It's not a process that rationality can survive.

The old method of communicating through the paper medium was methodical in correcting errors. People got accustomed to a process that could be relied upon for sorting out falsehoods. People were then caught off guard by scam methods of reality control that developed, in part due to the internet but also due to increased social complexities, while conservatives dismantled standards of normalcy in politics and throughout society." ...

Renewable Transition

The US transition to renewable electric generation is proceeding down a path which assures that electric rates will rise. Wind and solar are “source of opportunity” generators, producing electricity when the wind blows and the sun shines. They are intermittent, unreliable, non-dispatchable sources of electricity, which require backup from conventional generation sources or storage when they are not producing electricity. The renewable generating capacity connected to the grid is redundant capacity, in that it cannot replace conventional generation capacity, though the electricity it generates displaces electricity generation from conventional generators.

This duplication of generating capacity increases electricity infrastructure investment, thus increasing required return on investment and consumer electric rates. The addition of the renewable generation combined with the requirement to retain conventional generation, in the absence of electricity storage capacity, decreases the quantity of electricity generated by the conventional generating plants while increasing the cost of the electricity they do generate, since plant investment must be recovered from decreased generation volumes. The subsidies and incentives provided for renewable generation reduce the cost of the electricity they produce to consumers by transferring that cost to taxpayers, most of whom are also consumers.

The renewable energy industry is very quick to point out that the cost of the electricity it produces is declining and, in some cases, is cheaper that electricity produced by conventional sources. However, this is a faulty argument since renewable electricity is not reliable and dispatchable. The renewable energy industry asserts that providing transmission access and the storage capacity necessary to make renewable electricity dispatchable is the responsibility of others, such as the utility industry. This position allows the renewable energy industry to maintain the fiction that renewable energy is low cost and would result in rate reductions. Transferring this responsibility to the utilities also allows the renewable energy industry and its allies in government and the media to blame rate increases and grid unreliability on the utilities.

Logic suggests that the storage capacity required to render renewable generation reliable and dispatchable should be co-located with the wind or solar generation. The generators produce DC electricity and batteries store DC electricity. Inversion to AC power at transmission voltage would occur when the capacity of the generation / storage facility was dispatched. This approach limits losses to the in and out losses of the storage system and the energy lost in the inversion to AC power at grid voltage.

Remote location of the storage required to achieve reliability would require that the DC electricity generated at the site be inverted to AC electricity at transmission voltage, transmitted to the storage facility, rectified to DC electricity at storage voltage for storage, then inverted to AC electricity at transmission voltage again for dispatch. These multiple DC to AC to DC to AC conversions cascade the losses associated with each of the conversions.

Regardless of the transmission and storage approach pursued, the conventional generation fleet cannot be decommissioned until a fully dispatchable alternative is in place and operating. However, even after the renewable generation and storage infrastructure replaces the conventional generation infrastructure, electricity rates would still likely be higher until the cost of the required storage infrastructure declines significantly.

So, What Exactly Is Long-Duration Energy Storage?


"Long-duration storage occupies an enviable position in the cleantech hype cycle. Its allure has proven more durable than energy blockchain, and its commercialization is further along than super-buzzy green hydrogen.

Depending on who you talk to, long-duration storage technology can knock out coal and gas peaker plants, turn renewables into round-the-clock resources and generally pave the way for a carbon-free grid.

But beyond the high-level predictions, it’s hard to find a consistent definition of what this category actually means and exactly what it's supposed to do. That's largely because a market for such things hasn't really existed.

That’s starting to change. On October 15, a coalition of community-choice aggregators in California released the first major request for proposals targeting long-duration projects. To qualify, plants must be:

  • 50 megawatts or greater
  • Able to discharge electrons at that level for eight hours or more
  • In operation by 2026

Companies interested in this process cover a range of technologies, including pumped hydro, gravity-based, compressed air and flow batteries, as well as current market leader lithium-ion batteries.

GTM previously covered the main technologies vying for this emerging grid role and recently published an explainer on green hydrogen, another long-duration contender. In light of the new effort to actually buy some of this stuff, GTM has compiled a guide to why it matters, what products and companies are competing to supply it, and what hurdles this category faces." ...

Gas Generation Phaseout

The US currently generates more than 500,000,000 Megawatt-hours, or approximately 25% of electric utility annual electricity production, in coal-fueled generating stations, which the Administration has said will all cease operation by 2030. The US currently generates more than 800,000,000 Megawatt-hours, or approximately 37% of electric utility annual electricity production, in natural gas fueled generating stations, which the Administration has said will all cease operation by 2035. US natural gas fueled electric generation has more than doubled over the past 10 years because of the lower cost of natural gas and the higher generating efficiency of natural gas combined cycle powerplants.

The US currently generates 338,000,000 Megawatt-hours, or approximately 8.4% of all utility-scale electric generation. This electricity is generated by approximately 60,000 wind turbines with a total nameplate capacity of 122,465 MW operating at an average capacity factor of approximately 32%.

Replacing the generating capacity of the US coal-fueled generating fleet would require installation of approximately 625,000 MW of wind turbine rating plate capacity, plus the electricity storage capacity to store the output of the wind turbines for the maximum number of days duration of a potential “wind drought”. Additional generation capacity would be required to recharge storage after such a “wind drought” while meeting the contemporaneous demand on the grid.

Replacing the generating capacity of the US natural gas generating fleet would require installation of approximately 1,000,000 MW of wind turbine rating plate capacity, plus the storage capacity required to make the wind generation reliable and dispatchable, and the additional generating capacity required to recharge storage after periods of low/no wind generation.

US wind turbine installations peaked in 2020 at 14.2 GW (14,200 MW). Installation of 625,000 MW of wind turbine rating plate capacity over the period 2022-2029 would require installation of an average of 78 GW of new wind turbine generating capacity per year, or 5.5 times the capacity added in 2020. Installation of an additional 1,000,000 MW of wind turbine generating capacity over the period from 2030-2034 would require installation of an additional 200 GW of new wind turbine generating capacity per year, or 14 times the capacity added in 2020.

The current installed cost of new wind turbine generating capacity is approximately $1.3 million per MW. Assuming anticipated cost reductions resulting from increased manufacturing volume would be offset by cost increases resulting from increased demand for the rare earth materials required for fabrication of the wind turbines, the total cost of replacing existing fossil fuel electric generation with wind generation would be approximately $2 trillion. This estimate does not include the cost of the land on which the wind turbines are installed, the cost of the storage batteries required to make the wind capacity reliable and dispatchable and the cost additional transmission infrastructure required to connect the wind farms to the existing electric grid.

The replacement of both the coal and natural gas generating capacity would be deferred toward the ends of the required decommissioning periods to assure grid reliability through the transition, as operating experience was gained with the replacement wind and storage infrastructure.

A Victim of the Climate Wars: A Warning from the U.K.


"Shell’s decision to pull out of the Cambo North Sea oilfield-development project in early December — which could have also provided enough natural gas for 1.5 million homes for a year — may not seem like something that should concern Americans. Check a little more closely, though, and this grim tale begins to look a lot like an example of how our own oil and gas production is going to be — or is already starting to be — constrained, not necessarily by legislation but by a combination of regulatory overreach, activist agitation, and the increasingly malevolent influence of financial institutions. Many of those in the last group on that list are major institutional investors out to advance a socio-political agenda unconnected, whatever they may claim, to the generation of financial return for their clients. This agenda is often sold under the guise of “socially responsible investing” (SRI), and particularly these days, as “ESG,” a peculiarly virulent variant of SRI under which actual or prospective investments are not only assessed for the money they might make but also for how they score against certain environmental, social, and, much more reasonably, governance benchmarks.

In other instances, the pressure will be from banks, unwilling to help fund fossil-fuel projects that may cause them difficulty with activists, ESG-touting institutional investors, and, before too long, regulators, specifically central banks citing “climate risk.” That this risk is illusory doesn’t matter; that the illusion is useful does. It should be stressed that “illusory” refers not to the question of climate change but to the danger it might pose to our lending institutions.
