Each year, as much as half of the energy that goes into powering industry is lost as waste heat, according to the U.S. Department of Energy. That’s a big resource disappearing out the door. But we can do something about it with cogeneration — or combined heat and power — a technology for capturing so-called “waste heat” and putting the energy back to work.
Cogeneration works best when power plants are close to the infrastructure they serve — factories, major buildings, mine sites and so on. But the savings they drive are significant for overall efficiency, reduced fuel consumption — and greenhouse gas emissions.
