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. Talk about an upgrade! Just like every other power source, hydro creates some environmental concerns, including emissions and potential damage to wildlife at dammed reservoirs. But there’s no arguing it has a clean, renewable role to play in our country’s energy future.
