Wind power and solar photovoltaics found to have higher energy returns than fossil fuels

A key issue in net energy analysis is the omission of the effects of end-use efficiencies on the energy returns of technologies. Now, an analysis shows that these effects strongly favour the energy returns of wind power and solar photovoltaics, which are found to be higher than those of fossil fuels.
