Top Five Energy-Saving Tips
1. Turn thermostats down by 3 to 5 degrees on your furnace and water heater. Yes, this may mean wearing more clothes in the house. That's one of things they're for. And if you can't hold your hand under the hot water, it's too hot!
2. Turn the heat down further when you leave the house for the day, and turn it down when you sleep at night. If you have a programmable thermostat, even better - you can program it to do this for you, and set it to bring the heat up before you get home and before you get up.
3. Get your furnace tuned and cleaned every other year; replace the air filters at least annually if not seasonally. Make sure heating units or registers are free and clear. There's no sense in heating the back of the couch.
4. Next to space heating, water heating uses the most energy. Wrap your water heater with insulation. Wash your clothes in cold water. Consider whether it's necessary to shower every day (Heresy!), especially in the winter. Take shorter showers when you take them.
5. Turn off the lights when you leave the room, even if it's just for a moment. In rooms with track or recessed lighting, where multiple bulbs go on and off from a single switch, consider removing some bulbs or lowering wattage.
