E R O E I ...what does it mean? (Long series of articles, not all finished yet) No, it is not something that those dwarfs with the funny caps sing. It means: Energy Returned On Energy Invested OK, what does THAT mean? Here is an easy explanation. First, let's break this concept down into smaller chunks: ENERGY INVESTED is this - In order to ACQUIRE energy, it TAKES ENERGY. In order to TRANSPORT a form of energy, TAKES ENERGY. In order to STORE energy, TAKES ENERGY. In order to USE energy, also TAKES ENERGY. ENERGY RETURNED is this - After you have taken into account all the energy used above...how MUCH ENERGY do you have left? OR How much energy does it actually COST in order to USE a particular form of energy? eroei.com
