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.

Even without pumping, hydroelectricity is great to complement intermittent storage. A dam is storing a lot of potential energy that can be released or not at the right time.

There is a big dam close to where I live. In winter the level goes down progressively and as soon as spring comes back, the solar panels are producing again and the electrical demands goes down so the lake level goes back up progressively.

In summer the lake is full so all the tourists can enjoy the activities on the water.
