πŸ‘ New rule of thumb for AI energy use: One prompt = one second in the microwave

A simple AI query uses about 0.3 watt-hours of electricity. A microwave at around 1,000 watts uses about 0.28 watt-hours per second. So a simple AI query corresponds to roughly one second in the microwave.

πŸ’‘ Renewable electricity overtook coal as the world's largest power source in 2025

Solar and wind accounted for 99% of the growth in global electricity demand during 2025. Solar energy grew by 636 TWh – more electricity than all LNG exports through the Strait of Hormuz can produce. For the first time, coal power accounts for less than a third of the world's electricity generation.

🚧 The world's first geothermal plant with 10 to 100 times higher output per well is now being built

Project Obsidian will be the world's first geothermal power plant to extract energy from rock at 300 to 500 degrees Celsius. The millimeter wave drilling technique allows drilling to reach depths and temperatures that conventional drills cannot handle.
