Turn down the heat and air conditioning when you aren't home.

Try using a programmable thermostat or setting your thermostat yourself to 68 degrees while you are awake and lower it to 60 degrees while you are asleep or away from home. In the summer, keep the thermostat at 78 degrees while you are at home, but give your air conditioning a rest when you are away. This will allow you to save about 10% a year on your home energy costs. If every house in America did this, our total greenhouse gas production would drop by about 35 million tons of CO2. This is about the same as taking 6 million cars off of the road.

Choose energy efficient appliances. 

Because they use less energy, EnergyStar appliances like refrigerators can reduce carbon pollution, and have a big impact on your energy bill. Plus, choosing energy efficient products is easy -- just look for the EnergyStar logo. EnergyStar products typically exceed the federal energy standards by at least fifteen percent. When buying appliances that use the most energy in your home, like heaters, air conditioners, water heaters and refrigerators, also use the Energy Guide card posted on the appliance to help you choose the one with the lowest annual energy consumption.

Warm up your home with insulation.

Was your house constructed before 1980? If so, it could be one of the 80% of American homes built without enough insulation. This means your home heating costs could be going through the roof, literally. The North American Insulation Manufacturers Association has tips for both finding and getting the most out of a contractor to fix this problem and for doing it yourself.

Change your home's air filters.

Heating and cooling uses about half of the energy in a typical home and can account for about $1,500 a year in annual costs. Click here to read about how you can conserve energy by doing some basic home maintenance like replacing air filters and insulating your heating ducts.

Make the switch to compact florescent bulbs.

According to the government's EnergyStar program, if every American home replaced their five most-used light fixtures with EnergyStar rated compact fluorescent the savings would add up to $8 billion annually in energy costs. That's like taking almost ten million cars off the road. CFL's are widely available, affordable, and they last ten times longer than traditional bulbs.

Wash your clothes with cold water.

If you usually use hot water for your laundry you can cut your energy consumption in half by choosing warm water, and up to ninety percent if you choose cold. Your current liquid laundry detergent should work fine. If not, special cold water detergents are available. Your shirts and pants should be just as clean, and you'll thank yourself when the electricity bill arrives.
