Co-generation takes energy that is wasted or dissipated by heavy industry and uses it to generate power.
We think we could make about 19 to 20 percent of U.S. electricity with heat that is currently thrown away by industry.
Tom Casten, chairman, Recycled Energy Development
One major barrier to widespread adoption of co-generation is the same as that facing home solar. It’s difficult and sometimes impossible to sell the power back into the grid. But imagine the savings, both in dollars and greenhouses gases, if all that wasted energy was turned into electricity.
