Futures Knowledge Explains Energy Return On Investment - EROI
Energy return on investment (EROI) is the ratio of energy delivered to energy costs. For example, a power plant generates electricity but it also uses some amount of primary energy in construction, operation & maintenance, generation, transport, decommissioning, and other related activities during the plant's life cycle. Thus energy return on investment (EROI) of a power plant is the ratio of total energy which would be generated and primary energy which would be consumed to produce that over the entire plant life cycle.
