  •  Urban/Suburban Transport: TROLLEY BUSES!!!! (6+ / 0-)

    All you need to do is swap in an electric motor, string overhead wires around the bus route, and add the power pickup arms on top of the bus. These are still running in San Fran; every major city in the world used to have them by the thousands.

    First there's no batteries, so you're not spending energy dragging millions of pounds of dead weight around towns. Second there are no losses from charging and discharging the batteries. Third there are no battery disposal and recycling energy and economic costs. Fourth you don't have to build any new fleets or lay an inch of rail, nor purchase a foot of right-of-way for anything, and you can add and change routes as easily as stringing cable.

    Most important, you shift your "transportation" energy use onto the "electricity" grid which is the easiest to decarbonize right now, because a hardwired bus doesn't require any mobile fuel. This transportation is instantly as green as your grid.
