The ongoing drought in the western US depleted reservoirs and reduced hydropower generation. Fossil fuel power plants filled the gap but that has led to increased air pollution
3 February 2023
Record low water at reservoirs across the western US – a stark sign of the region’s megadrought-driven water crisis – means less electricity can be generated at dams, which has led to more greenhouse gas emissions and air pollution from fossil fuel power plants being used to fill the hydropower gap.
On average, about 26 per cent of the electricity for the western US comes from hydropower and 50 per cent comes from fossil fuel plants …
