I noticed that the outdoor floodlight in my rented home didn't even have an off switch. It was hard-wired into the same circuit which powered all of the lights and appliances in the kitchen and living-room. Is it really cheaper to run lights continuously rather than provide a power switch? What can we do about this? Is this common in other parts of the world? GreenProphet challenges readers to count these lights and try to do something about them.
