So I just heading out the door, but here's my challenge for the day: turn off the light when you leave the room, even if it is only for a short period.
Lighting accounts for 30 to 50% of a building's energy use, or about 17% of total annual U.S. electricity consumption. Simply turning off unneeded lights can reduce the amount of energy used for lighting up to 45%. At the same time, using less energy reduces air pollution, global warming and other environmental impacts associated with electricity generation.
Happy weekend!
