In one factory retrofit, the company Recycled Energy Development (RED) is projecting that they can produce 1/3rd of the power a West Virginia factory needs purely from the excess heat they are already generating.

Michael Kanellos writes, "The U.S. consumes around 100 quads (100 quadrillion BTUs) of energy a year, and 55 to 60 quads get dissipated as waste heat, according to [UC Berkeley professor] Arun Majumdar."

"Thus, there is a lot of waste heat out there and it could be cheaper than solar."
