Things have escalated way past the Constitutional-Calvinball effort during Trump I to revoke California’s Clean Air Act waiver — as I discussed in “Democracy or Carbon Oligarchy?” (Available at link.springer.com/9783032245755 ) 🔌💡
Under Pruitt’s successor, Andrew Wheeler, the major immediate front in the Trump-administration EPA’s campaign to undo Obama-era regulatory policy changes moved to the theater of fuel efficiency and emissions standards. On August 1, 2018, “the EPA and Transportation Department proposed taking away California’s waiver as part of a rule that would freeze mileage standards for these vehicles at roughly 37 miles per gallon from 2020 to 2026,” as opposed to retaining Obama-era standards of over 50 miles per gallon by mid-decade (Eilperin and Dennis 2019). The earlier, more stringent standards has been incorporated into policy at the state level, in California, as part of a “coordinated package” of emission standards
addressing smog and greenhouse gases, along with a mandate for
adopting electric and fuel cell vehicles collectively known as the “Advanced Clean Cars Program” (Grab et al. 2018, p. 3). The proposed revocation would affect not only California, but also 12 other states and the District of Columbia that had adopted California’s standards—as they are explicitly
enabled to do under federal legislation, specifically Section 177 of the Clean Air Act Amendments of 1977; together, these 13 states “account for over a third of U.S. auto sales (Grab et al. 2018, pp. 1, 4)…

Yeah, that’s part of it. Here’s the chart for total fossil fuel production (equalized in terms of terajoule energy content, and indexed to 1990)
“… British fossil fuel production
was the most volatile over this period: after rising to a peak in 2000, it then declined to less than half of its 1990 level by 2015.

The outstanding performer in decarbonization, as represented in Fig. 1.1, is the United Kingdom. 2022 per capita carbon dioxide emissions in the U.K. were roughly halved—more than 53% lower than they were in 1990.

Moreover, this decline in emissions was relatively steady, in contrast to the reversal of trend in fossil-fuel production shown in Fig. 1.2, from initial growth to eventual decline. As we will see in Chap. 4, sectoral and policy changes in Britain over this period were as influential in generating this outcome as the underlying economic and geological processes of rising costs and depletion, although all of these factors are necessary to understand
how such significant decarbonization was initiated.”

I argue in my book — “Democracy or Carbon Oligarchy? Climate & Energy Policy between Crisis & Decarbonization”, available at link.springer.com/9783032245755 — that we can learn quite a bit from 🇬🇧’s relative success in bringing down CO2 emissions. But denialist ‘populism’ sleeps for no one. 🗺️ 🌱 🔌💡

Anyway, bipolarity in 🇺🇸 energy policy is, however, not a new phenomenon. Rapid reversals are the norm. Perhaps presidentialist institutions have something to do with this? 🗺️ 🔌💡 link.springer.com/9783032245755 — “Democracy or Carbon Oligarchy? Climate & Energy Policy between Crisis & Decarbonization”

It’s easy to forget how different things were in 2012. Mitt Romney ran against the same Obama-era “picking winners and losers” program in which the biggest winner was arguably Tesla, as I also discuss in my book “Democracy or Climate Oligarchy?”, available at link.springer.com/9783032245755 🔌💡
… Given such a rapid increase and scaling-up of financial resources for
what was a relatively small and volatile segment of the energy sector
involving acknowledged risks and unproven technology, it was unsurprising
and inevitable that some of this new money would be spent on
ultimately unproductive ventures such as the solar cell maker Solyndra,
in addition to relative success stories such as electric vehicle (EV) manufacturer
Tesla. … The partisan split over energy spending was
already developing during the 2012 presidential election campaign and its
televised debates, when Republican Party presidential candidate Mitt
Romney questioned the practicality of government aid for the commercialization
of renewable energy technology, and the wisdom of ‘picking of
winners and losers’ inherent to the conduct of any industrial policy. …

It’s Fredos, all the way down. I mean, it *is* hard to get the incentives right when you’re in a loyalty- (not merit-) based apparatus and if you’re likely to be an old, white party apparatchik who is used to chasing after a median voter who you assume is just like yourself.

Yes. Stop performatively beating yourself up on “not doing enough for the less-fortunate,” and focus on shoring up the political institutions & guardrails instead.
…pointing to poor socioeconomic performance by democratic governments and citizen anger about that performance as the primary drivers of democratic backsliding is a mistake…
