I ran across this piece that shows a breakdown on household electricity use. I anticipate the lighting use will drop by 50% due to the emergence of cost effective, high efficiency LED bulbs. As they replace the aging fleet of incandescent and compact fluorescent bulbs lighting will use less electricity. Add to that that LEDs are expected to nearly double in efficiency over the next decade and there is a recipe for more light at less cost. High efficiency LEDs also bring down the electricity use of TVs and computer screens. All of this reduces heat produced so that air conditioning doesn’t need to work as hard.
