Wisconsin-based Bill Harris knows all about upcycling. His company, Renewable World Energies, is renovating aging, 100-year old hydroelectric plants and boosting their energy production by as much as 50 percent with modern turbine technology.

But there’s no arguing it has a clean, renewable role to play in our country’s energy future.
