Not only will it save energy when lights are on timers, but burglars and prowlers will have no idea that you're in the Bahamas basking in the sun. Set your timer to turn lights on and off at different times on different days. Your home looks more lived in this way. 10 Install dimmers. 11 Check your lamp shades.
Many shades are decorative but absorb light or reflect it in the wrong direction.
Without our attempting to be your interior decorator, you may want to consider switching to a more efficient shade in a lighter color. 12 Use task lighting. If you're working diligently at a desk or workbench, other light in the room could be turned off or dimmed. If you, like Joe Brown, replaced 4 incandescent bulbs with compact fluorescent bulbs, you'd save the equivalent of 2,400 lbs. of coal over the life of the bulbs.
