From what I read? Hydroelectric power produces about 45% in renewable energy and about 6.1 % total electricity.
Approximately what percentage of the United States’ electricity supply comes from hydroelectric power plants? 6 percent 86 percent 26 percent 56 percent
Yes.
I don't know about total US ... But the electric districts I've been in, in the Pacific NW, it's always been over 90%.
