Agreed, electric is a great way to mow a lawn, and gas lawn mowers are a poor exemplar of the ICE's potential.
Patrick, electricity transmission losses are around 10%. It's the 35% efficient fossil fired generation that makes the arrangement as a whole only a little more efficient than an ICE + refinery.
By the time you add enough batteries to get 100mi of range, you've added enough weight to raise emissions to a level higher that of hybrid of similar specs. Most studies on the matter recommend a HEV or PHEV with not much more than 10mi range as being far cheaper and having slightly lower emissions than a BEV.
Neil, Nissan says it's >22% loss in refining, and I've used 17% throughout my calculations. My number does account for the other energy and non-energy products produced alongside gasoline, as well as all the purchased energy used during the process.
16KWh per gallon. Until a coal phase-out is well underway, mass adoption of electric cars will not be very exciting.
