I wish I didn’t have to share this. But the BBC has decided to censor my first Reith Lecture.

Electrification + efficiency — not rolling back climate policy — is the real path to a competitive European industry.
High fossil fuel prices hit industry hardest, not the Green Deal. Undermining clean-energy commitments would only push investment elsewhere.

Why electrification, not repealing green laws, will save Europe's industry
According to Oxford professor of energy Jan Rosenow, rapid electrification of Europe's industry, not rolling back the EU's Green Deal, will save European industry.

Epic take-down of Roger Pielke Jr's appallingly shoddy academic "work", which he's used--as an attack dog of the Koch Brothers-funded think tank AEI--to discredit the case for climate action:
In a 2024 paper criticizing the 'billion-dollar-disasters' database, Roger Pielke Jr. published analysis that is best described as a Russian-doll of errors.

In a recent paper called Scientific integrity and U.S. “Billion Dollar Disasters”, Roger Pielke Jr. published a chart that's so bad I've devoted a whole essay to debunking it.

Exxon Halts Baytown Hydrogen Project Amid Weak Market Demand
ExxonMobil has paused its planned Baytown, Texas, hydrogen project—once expected to be among the world’s largest—citing weak customer demand and high costs tied to carbon capture. The delay underscores broader headwinds for hydrogen investments across the U.S. energy sector.

If coal had gone down in the US, or had gone down as expected in the EU, then global coal would have declined.
Or, if India (or China) had grown as the last few years, coal would have risen.
Basically, coal in 2025 is on a very delicate balance.
Similar case for oil (not as drastic).
