>far past the most stringent fuel economy minimums. Only because the efficiency of generating and transmitting electricity isn't included. Electricity generation is generally only ~30% efficient. Transmission and grid for on-demand power slightly reduces efficiency further, while non-on-demand sources like solar and wind result in higher than apparent grid inefficiencies, since the grid investment tied to it is also only as efficient as the power source. Solar efficiency is 20%, and lower when you factor in grid inefficiencies due to its variability. Yes, the cost of solar already reflects these inefficiencies (land use, etc), but so does the costs of other fuels. And most batteries aren't getting anywhere near the efficiency on the label either. All that heat coming off the battery when charging (especially using a supercharger) isn't free energy either.
