The ongoing drought within the western US depleted reservoirs and diminished hydropower era. Fossil gas energy crops stuffed the hole however that has led to elevated air air pollution

Record low water at reservoirs throughout the western US – a stark signal of the area’s megadrought-driven water disaster – means much less electrical energy will be generated at dams, which has led to extra greenhouse gasoline emissions and air air pollution from fossil gas energy crops getting used to fill the hydropower hole.
On common, about 26 per cent of the electrical energy for the western US comes from hydropower and 50 per cent comes from fossil gas crops …
