Saving money by reducing lighting costs

A few more tips from Mary Hunt's article on saving money on your energy costs, this time specifically in regards to the lighting portion of your energy bill, which typically accounts for about 20% of your electricity bill.

• Switch to CFLs. It costs about a dollar a month to run a regular 100 watt bulb for 3 hours a day. If you use a compact fluorescent bulb (CFL), that cost drops to 25 cents a month. The Department of Energy estimates that changing a quarter of your home's bulbns to CFLs could cut your lighting bill in half.
• Turn your lights off. If you'll be gone for more than 5 minutes, better to turn your lights off.
