- Change Your Filters. Clean or replace the filter in your forced-air heating and cooling systems each month. Foam filters can be rinsed with water but be sure they are dry before replacing. Fiberglass filters need to be replaced periodically.
- Reduce Water Heating. Turn down the water heater temperature dial to 120 degrees F, or to the “warm” setting if you have a dishwasher. Be sure to check your manufacturer’s instructions for minimum water temperature.
- Try Efficient Lighting. Use compact fluorescent bulbs. They produce about three to four times as much light per watt as incandescent bulbs. While compact fluorescents are initially more expensive, they last up to 10 times longer.
- Charge Smarter. Put your laptop AC adapter on a power strip that can be turned off (or will turn off automatically) to maximize savings; the transformer in the AC adapter draws power continuously, even when the laptop is not plugged into the adapter.
