Renewable energy met all new demand for electricity in 2025, according to a new review of global power generation, halting the growth of fossil fuel-powered generation and highlighting the promise of clean sources like wind and solar.

The authoritative Global Electricity Review released annually by Ember, an international energy research organization, says clean sources — especially solar — are growing fast enough and are cheap enough that they are stopping new fossil fuel-powered electricity generation. Electricity from solar and wind increased while there was no change to the amount of electricity produced from burning fossil fuels.

“We’re really talking about a large-scale change in how the energy system works. And solar is among the most scalable technologies that can deliver fast change,” said Nicolas Fulghum, senior data analyst at Ember.

    A 4” pipe with 400’ of head altitude feeds a 3/4” nozzle pelton wheel with around 7000w @ 120v in a basic bush install. I am sure a well engineered system could provide double that or more, but a rooftop tank might run out at night unless it was quite big, and that is definitely micro hydro.
