Advocates of hydropower, America’s largest and oldest, but often forgotten, renewable energy source, are carving a major place for themselves in the Trump administration, eyeing the upcoming debate over infrastructure as a way to push for changes that would speed the approvals of water-powered projects.

“Too often in the infrastructure debate, we focus on civic works, which is important, but we want to highlight where there is this opportunity on the power generation side as well, and that starts with hydropower,” Jeff Leahey, deputy executive director of the National Hydropower Association, told the Washington Examiner. “Any plan that doesn’t address modernizing the licensing process for hydropower development misses an opportunity to create clean energy jobs and transform our nation’s energy infrastructure.”
