Investments in clean energy supply chains have been booming.
The animations below show the surge in investments in the U.S. and the acceleration in investments since 2021.
My students @Wellesley and I have been tracking this carefully at the-big-green-machine.com
Thanks to the Inflation Reduction Act & Infrastructure Law, the Biden-Harris Administration is making multi-billion dollar investments in clean energy, clean air, and the jobs of the future at least once a week (sometime several per week). They're rarely covered much, and never break through to the public, but they're all important.
Trump 47 + 2 months

By our count, in past month, 3 projects slowed and 4 advanced. Details below.

For the history of how climate became such a political lightning rod, check out "American Exceptionalism in a Warming World" in The Republican Reversal.

One source we drew upon for that article is this 2009 video from a Tea Party rally against the Waxman-Markey climate bill.
The rhetlplaybook was all about the threat climate action posed to an American way of life. Start at minute 1:03. youtube.com/watch?v=gFoJXiLv…

With over $100 billion dollars flowing into the US’s EV battery supply chain since the IRA was signed (supporting 157 new projects + over 60,000 new jobs), global carmakers have invested in this transition. Going backward would mean stranded assets. xitter.cf/_jay_turner/status/185…
Inflation Reduction Act + 27 months
My students at @Wellesley and I are tracking investments in the US EV supply chain.
Surprise: IRA + 27 months and investments jumped.
We are now tracking:
157 new projects
$101 billion in investments
63,718 new jobs announced
A short 🧵
