That's what really separates consumer electronics from cars: processing data requires (from a theoretical physics standpoint) a minuscule amount of energy, and there's a lot of room for improvement even with current technology.
Moving heavy things up hills or through air at high speeds requires a respectable amount of energy, and current technology is already within an order of magnitude or so to the theoretical peak efficiency.
