Is your number for electric cars including the losses of creating that electricity (coal is perhaps 30-40% efficient, solar around 15-20%). Otherwise, we're comparing apples with oranges. Or perhaps, since all energy (perhaps lets put nuclear aside for now) comes from the sun, we can compare system efficiency between solar energy input and energy/g/km output. Humans on bikes can also use the wind to help them; birds fly in formations that greatly increase system efficiency (much like pelotons)
