- Get a programmable thermostat. You can save yourself a lot of money by down the heat when you're away from home. Have the programmable thermostat turn the heat down when you leave the home and turn it up just before you return.
- Change furnace filters. Be sure you change your furnace filter every 1-3 months.
- Replace incandescent bulbs with compact fluorescents. Compact fluorescents use considerably less power and are well worth switching over to.
- Don't keep devices plugged in. Toasters and laptops, for instance, use power when they're plugged in. Unplug them after usage. Or, to make life easier, plug a few devices into a power bar
- Fix leaks. Assuming your walls are well insulated, the biggest source of heat loss from your home will be from windows and doors. Check for leaks around your door's and window's by holding a lit incense stick near the caulking. The smoke will tell you whether there's a leak or not! Fix the leaks with caulking or weatherstripping.
- Plastic film your windows. Install plastic film on the inside of your windows to reduce heat loss. Special film for your windows can be purchased at most home supply stores.
With these tips in mind, you can reduce your energy consumption, and -- most importantly -- your energy bill this winter!
