Droughts are cutting into California’s hydropower. Here’s what that means for clean energy.

The droughts that swept across the western US in 2021 sparked wildfires and damaged crops. But the historic lack of water also had an impact on one of California’s key sources of renewable energy: hydropower.

Hydropower is the world’s leading source of renewable energy, making up about 17% of electricity generation in 2020, but droughts are making it harder to rely on. As a low-carbon source of power, it’s essential in limiting emissions of carbon dioxide.However, droughts over the last two years have caused Californian reservoirs to dry up, leading to the closure of the state’s second-largest hydropower plant last year. This lost power can’t easily be replaced with renewable sources that fluctuate during the day like wind and solar, which likely means more electricity generation from other sources, and more emissions.
