Even more potential: residential energy consumption!
1.) Residential energy consumption is even bigger than for transportation.
2.) Insulation is cheap.
3.) It is more difficult and expensive to use alternative energy sources on vehicles than on stationary objects (buildings) where size, weight and energy storage do not matter.
