Petrol cars only see 18-25% of their fuel energy get to the wheels; EVs 87-91%. Heat pumps are 2 or 3 times more efficient.

Gustaf Degen @gustaf23.bsky.social · 12/11/2025So happy this is out as a preprint (for) now. Since measuring ATP is tricky, we used ATP biosensors in collab with @schwarzlanderlab.bsky.social to show that in chloroplasts without PGR5, NPQ and pmf are diminished, yet ATP levels unchanged. Balancing ATP/NADPH must be achieved by different means. 152
