"Fossil demand has been flat for industrial energy since 2014, for buildings since 2018, for road transport since 2019, & may peak for electricity this year. 2/3 of countries have already seen peak fossil demand in end-use sectors, & half the world has seen a peak in fossil fuels for electricity."
The Electrotech Revolution | Ember
The annual slidedeck from Kingsmill Bond and the Ember Futures team unpacks how electrotech is rewriting the economics and geopolitics of energy.

NEW from me: CO2 emissions in China have now been flat or falling for 18 months, the first time that energy demand growth at or above historical averages doesn't drive emissions up, thanks to the clean energy boom. 🧵👇

A historic turning point for clean heating in Europe: For the first time, in the first half of 2025 sales of heat pumps in Germany have surpassed those of gas boilers.
This is a big milestone, demonstrating that the transition away from fossil fuels in our buildings is not just a future ambition.

With the installation of an induction cooktop, I was able to shut off the fossil gas supplied to my 17-year-old home in Northern California. Here's how I did it.
