America’s hydropower industry is hoping to reestablish some of its former glory by making itself central to the nation’s transition to clean energy—and it’s turning to Congress for help. … Today, hydropower provides just a small fraction of the nation’s electricity and is quickly being outpaced globally by its clean energy rivals in new development. Now the industry, with help from a bipartisan group of U.S. lawmakers, hopes to change that trend. … The bill has gained early support from industry, environmental groups, Native tribes and even the Biden administration. But it’s also getting pushback from some advocates who say that expanding or extending the use of hydropower could actually worsen climate change and hasten ecological degradation.
