The environmentalists are always crying about how more than 5 percent of energy could come from wind and solar power. Why don’t they look around at the waste?
Go to the malls and store parking lots on a sunny day and look at all the lights still on. Are they needed? Also many people leave their outside lights on all day. In the cities freeway lights and other lights that are not needed are on all day.
I’m sure we could save more than 25 percent of energy use by turning off lights that are not needed.
