Energy: Where’s it Come From and Where Does it Go?

The annual chart from DOE/Lawrence Berkeley on where energy comes from and goes.

Ever wonder where our country’s energy comes from and goes to? This fascinating map from the Lawrence Livermore Laboratory shows in simple graphic terms where we generate energy and how much of it goes to various sectors. One of the fascinating aspects of this is everything you see in gray–“Rejected Energy.” What this really means is waste. Particularly in electricity, as much as 2/3 of all the energy created is lost during transmission and via other means before it actually does any work. All the more reason to generate your electricity right at home on your roof. This waste has to do with site and source energy and how t reduce the waste.  Combined Heat and Power installations are a beginning step in the reduction of waste
