"Hydroelectric dams are a major source of carbon-free electricity, but their output is way down in much of the West."
"When something reliable begins to look shaky, we should take notice. That’s what’s happening for hydroelectric power in much of the West, where severe drought has led to low water levels in the rivers and reservoirs that feed the power systems.
The Energy Information Administration is projecting a 13.9 percent decrease in hydroelectric generation this year compared to 2020, part of a larger picture in which renewable energy—which includes hydropower—is not growing as fast as scientists say is necessary to avoid the worst effects of climate change.
I wanted to know whether the drop in hydropower was a sign of a long-term shift that could be harmful to the transition to clean energy."
