I'm writing a book about what we're learned about #climate solutions over the past 25 years. More on that later.
It occurred to me that you might be interested in hearing about some of the books I've read that are important or fun, but not listed as climate books. A holiday 🧵 once a day.

Robert focuses on local control of things corporations can directly change, and separates them from GHG emissions that are outside direct control. I find this more informative and useful than the scope 1,2,3 discussion which muddles the discussion in many cases.

Where would we be today if all of the money that went into carbon offsets, and all of the effort that went into shaming people for their personal carbon emissions, went instead to supporting politicians and policies that would effect systemic change (e.g., energy policy, emissions disincentives)?

200 charts in @nathanielbullard.com 's annual energy assessment, but this is the one that surprised me. We spent 25% of our money on firewood in the 1800s? That's stunning.

Clean energy supporters hope for high oil prices due to reduced supply, but the opposite is happening. Despite global tensions that should increase price, it is falling. I read this as the market pricing in future demand reduction due to electric vehicles esp. in Asia. OECD peaked already in 2006.

I’ve been thinking about learnings from 25 years of climate work.
Highly relevant right now: we need electricity to be cheap to harvest the climate benefits of renewables. Cheap power, and lots of it, solves a lot of problems.
