Electrification could cut total world energy demand
Original: Electrification efficiency: The world will need less energy after the transition
A new analysis argues that shifting the global economy to electricity will make energy use far more efficient, so the world will actually need less total energy after the transition than it does today. Electric motors, heat pumps and EVs convert far more of their input into useful work than combustion-based systems, which waste most of their energy as heat. Commenters on Hacker News are debating how much these efficiency gains can offset rising demand from data centres and industrial growth.
Why now: Debates about energy demand from AI and electrification are making efficiency claims newly relevant.
