He emphasized that EROI by itself is cannot determine whether one source of energy is better than another: coal has an EROI of 80 while hydro has an EROI of 40. Is coal twice as "good" as hydro? Dave described how net energy to society starts declining dramatically around EROI=9 and how bio-fuels are well below this number. He believes we need to carefully separate the energy used for construction vs . energy used for O&M when evaluating resources. Solar and wind have high embodied energy compared with fossil fuel production facilities but lower O&M costs from an EROI point of view.
