According to the Washington Post, a new report out from the U.S. Department of Energy finds that there is room to grow our country’s hydropower sector, aka energy made from water, like from dams.
From the article: "According to the report, the nation’s current hydropower has an electricity-generating capacity of about 101 gigawatts (or billion watts of instantaneous power generation) that could grow by about 50 percent by 2050. That equates to nearly 50 more gigawatts, which would add a few percentage points to hydropower’s overall contribution to U.S. electricity."
Many agree that there is potential for more hydropower in this country, but there may be some dangers as well, such as affecting wildlife and changing rivers. So any work would need to be done carefully.
