Yeah, obviously the thing we want to maximize is the energy output per labor input, since the whole point of having this energy is to use as an input to further labor-saving processes. Chopping wood with an axe is bad on this scale. Coal and oil are much better. Renewables have the potential to be even better, if they aren't already. Thanks for these, they are a good way to voice something that I've always felt was a problem with the EROI crowd's thinking.
