"Facing a climate crisis, environmental groups and industry agree to work together to bolster hydropower while reducing harm from dams."
"WASHINGTON — The industry that operates America’s hydroelectric dams and several environmental groups announced an unusual agreement Tuesday to work together to get more clean energy from hydropower while reducing the environmental harm from dams, in a sign that the threat of climate change is spurring both sides to rethink their decades-long battle over a large but contentious source of renewable power.
The United States generated about 7 percent of its electricity last year from hydropower, mainly from large dams built decades ago, such as the Hoover Dam, which uses flowing water from the Colorado River to power turbines. But while these facilities don’t emit planet-warming carbon dioxide, the dams themselves have often proved ecologically devastating, choking off America’s once-wild rivers and killing fish populations.
So, over the past 50 years, conservation groups have rallied to block any large new dams from being built, while proposals to upgrade older hydropower facilities or construct new water-powered energy-storage projects have often been bogged down in lengthy regulatory disputes over environmental safeguards.
The new agreement signals a desire to de-escalate this long-running war."
