1As the United States pushes to use more low-carbon energy,
2there has been a recent improvement in relations between the hydropower industry and some environmental groups.
3The recent compromises are found in President Joe Biden's infrastructure law,
4which puts $2.5 billion toward projects including dam removals as well as improvements to existing structures for hydropower and energy storage.
5Ted Illston of American Rivers, a group that has pushed for dam removals on environmental grounds, recently told the Associated Press that the group recognizes "that (hydropower) is probably going to play some role in the transition. It's certainly better than coal."
6Hydropower uses flowing water to move turbines connected to generators.
7It is the oldest and second-largest sort of renewable energy in the U.S. after wind power.
8In 2020, it accounted for roughly 7 percent of the electricity generated in the country.
9The industry has not received as much federal money as wind and solar, but sees room for growth.
10Of the 90,000 dams in the country, about 2,500 produce power.
11Non-powered dams could produce enough power for 9 to 12 million homes,
12said an estimate by the Electric Power Supply Association based on federal data from 2012.
13In southwestern Pennsylvania, Rye Development, a Boston-based hydropower company, is adding turbines to eight dams to generate electricity.
14The company says the improved structures will limit damage to the rivers' water quality and fish.
15Rye is among the companies that sees an opportunity to expand hydropower production at existing dams while working to minimize environmental harms.
16Part of the difficulty is that most dams in the U.S. were built more than fifty years ago.
17The risk of dam collapses has led to increased dam removals or demolitions in recent years,
18with more than 40 percent of the country's dam removals in the past century happening in the last ten years.
19Last month, federal officials moved a step closer to approving what would be the largest dam demolition in U.S. history.
20Removal of the four hydroelectric dams on the Klamath River near the Oregon-California border would help save the river's salmon and other fish species that cannot reach breeding areas because of the structures.
21Despite some recent improvements in relations between the hydropower industry and environmental groups, there are still disagreements.
22On Maine's Kennebec River, environmental groups and state environmental agencies are pushing for the removal of four hydropower dams that block endangered Atlantic salmon from reaching key areas.
23The dams make about 5 percent of the state's renewable energy.
24Shannon Ames of the Low Impact Hydropower Institute said,
25"It's very easy for individual river systems to get lost in the message of climate change and the need for renewable energy."
26With drought affecting hydropower production in America's West, the industry has a more direct path to growth in eastern states.
27In Pennsylvania, Rye met with the Low Impact Hydropower Institute early in its process and is among a small number of companies seeking certification from the group.
28To get certified, companies must show their structures meet protections for endangered species.
29The group says its environmental requirements are often stricter than state or federal rules.
