100 Ways to Reduce Your Impact

Step 18 Turn off the lights when you leave the room

This is a pet peeve of mine. I hate it when people leave lights on when they are not using them.

30% of a home's energy usage comes from the lighting. Turning the lights off when you leave the room can dramatically reduce the amount of energy used for lighting.

Motion sensors might help too. They are not hard to install usually. Unfortunately, they aren't that cheap.

No good if you have pets though...

I admit I don't know about the cheaper $30 ones from hardware stores, but the alarm grade ones can be tuned so pets aren't a problem.. so perhaps there are some out there that can be.
