HAMILTON, Ohio (AP)

There is mounting political pressure to get more energy from alternative sources and developers are pushing ambitious projects to exploit America’s biggest rivers for power.

“Some of these applications have been around for decades, but there’s renewed interest now,” said Jeff Hawk, spokesman for the U.S. Army Corps of Engineers’ Pittsburgh district. “We’ve seen a spurt of applications; we’re busier now than ever.”

A new generation of low-impact hydroelectric plants is expected to light up the Ohio River Valley. Along the Mississippi River, a city and a small startup firm have separate hopes of harnessing that artery’s energy potential either through a few big turbines or thousands of tiny, submerged ones.
