Consider maximizing the natural light in your home or office by pulling up the window blinds and turning off the lights during the day. Just make sure the sunlight is not causing indoor temperatures to rise to uncomfortable levels, thereby forcing you to run your AC for a longer period.

If you keep the lights off during the day and use natural light instead, you might save $50 to $60 per year on your electricity bills, depending on the wattage ratings of the bulbs you turn off.

If every U.S. household used natural daylight for an additional two hours per day, and turned off just a single 100-watt bulb during that time, the energy saved would equal more than 7.5 billion kilowatt-hours per year-enough to meet the annual lighting needs of every household in the state of New York.
