Cogeneration Goes Global

Sometimes what’s old becomes new again and cogeneration, which is more than 130 years old, is gathering momentum across the world.  Combined heat and power (CHP), also known as cogeneration, is the simultaneous production of electricity and heat from a single fuel source, such as natural gas, biomass, biogas, coal, waste heat, or oil,” reports the … [Read more...]

Combined Heat and Power: Not the Brad and Jen of Energy, But….

I hesitate to start this blog with the words “combined heat and power.”  You might stop reading.Okay, so it’s not the Brad and Jen of energy. (That would be solar and wind.) But what it lacks in glamour, it makes up for in constancy and results. It’s an old guy, been around for about a century. And while its name might not sound green, it offers … [Read more...]

Unless you are making kilowatts, the most efficient investments are off the … [Read more...]

Energy waste the size of Japan

By Elisa WoodJuly 22, 2010Here is a startling fact: US power plants waste more energy than many countries use, including advanced economies like that of Japan. The wasted energy is in the form of heat thrown off when power plants produce electricity.This is one of the points being brought to light by the International District Energy … [Read more...]

Is waste heat the silver bullet?

By Elisa WoodAugust 13, 2009The energy industry tends to get stuck on certain words. Silver bullet is one of them. Insiders and policymakers often like to say there is no silver bullet to fix US energy woes. We need a portfolio of solutions – renewables, efficiency, smart grid, transmission expansion, coal sequestration, etc.That may be true, … [Read more...]

Brad Pitt, Angelina Jolie and combined heat & power

By Elisa Wood Dec. 4, 2008The universe contains many mysteries. A big one for me is: Why doesn’t the United States use more combined heat and power (CHP)?It requires an energy geek, of course, to even ask that question. Most of the world knows nothing about CHP, even when referenced by its other name: cogeneration. So it was heartening to see … [Read more...]
