OverviewHistoryApplication to various technologiesNon-manmade energy inputsCompeting methodologyRelationship to net energy gainEconomic influenceCriticism of EROI
In energy economics and ecological energetics, energy return on investment (EROI), also sometimes called energy returned on energy invested (ERoEI), is the ratio of the amount of usable energy (the exergy) delivered from a particular energy resource to the amount of exergy used to obtain that energy resource. Arithmetically the EROI can be defined as:

Ethanol and Energy Return on Investment (EROI) | SpringerLink
A good bit more, as Hall ( 2011) shows in this example of what EROI means: If you use twice as much energy to obtain oil as the energy in the oil can produce (EROI = 0.5:1), then you have a negative energy return of −0.5 and a lot of explaining to do. If you used one unit of oil to get one unit of oil (EROI = 1:1), you can stare at the hole

Introduction. Energy return on investment (EROI) is a method of calculating the energy returned to the economy and society compared to the energy required to obtain that energy and, thus, to measure the net energy produced for society ( Odum, 1973; Mulder and Hagens, 2008; Hall, 2011; Hall et al., 2014 ).
