Another easy change is to switch your lightbulbs!
Incandescent lightbulbs are cheap, sure. But they’re only cheap when you buy them. They don’t last a long time at all AND they drain energy like crazy.
Switching over to CFLs or LEDs may be a little pricy up front, but they CONSERVE energy and last 10x longer than regular lightbulbs.
So when your bulbs finally blow out, be sure to place a CFL or LED in their place.
Can’t decide between CFL or LED? LEDs are the best option!
