A great post from Angie’s list:

  • Adjust your thermostat/Keep it Clean: Heating, ventilation and cooling (HVAC) systems are your home’s No. 1 energy hogs.
  • A/C Savings: Each degree you dial your air conditioner above 78°F decreases energy usage and can save the average homeowner about $8 a month per degree. Dial it up when you’re not going to be at home – programmable thermostats make that chore easy.
  • Heating Savings: You can save as much as 10 percent on heating costs by keeping your thermostat set at 65 degrees at least eight hours a day. A programmable thermostat, which can be found for as little as $20, can take care of the dialing for you. Going down to 65 degrees when you’re away or asleep means you won’t even feel the sacrifice.
  • Even More: Check your furnace air filters every time you pay your gas or electricity bill and change them as needed, generally quarterly if you’re using quality filters. The cleaner the filter, the more efficient the HVAC system. A dirty air filter reduces airflow and can create costly obstructions in the unit.
  • Light Show: Lighting is your home’s fourth biggest energy hog. Turning lights off when you’re not in the room really will reduce energy costs – especially if you’re still using incandescent bulbs.
  • The Off Switch: Electronics are No. 5 energy hogs. Video game systems use about the same amount of power when they are in sleep mode as they do when they’re in use. So, after you conquer the Wii, turn the system off and then turn the TV off, too.
  • Pull the Drapes: Direct sunlight can raise room temperature as much as 20 degrees and trigger your A/C. Close the drapes when you’re away so you don’t cool an empty house.

In the Bathroom:

  • Cool it Down: Lower your water heater (Energy hog No. 3) base temperature to 120°F degrees. Your shower will still be steamy, and you’ll save by heating less water.
  • Stand up and Save: Baths generally use more energy than showers because you use less water in the shower, which means you heat less water.
  • A Bright Idea: You need a clear mirror view in the bathroom, but every bulb that lights your way costs money. You won’t notice the visual difference by replacing 100-watt bulbs with 60-watt bulbs, but you’ll see it in energy savings.
  • An Even Brighter Idea: Compact fluorescent light (CFL) bulbs use up to 75 percent less energy and last about 10 times longer than an incandescent bulb.

In the Laundry Room:

  • Lose a Quart: Drain a quart of water from your water heater (Energy hog No. 3) tank every three months to remove sediment that slows down heat transfer and lowers the efficiency of your heater. Follow your owner’s manual to accomplish this task because the type of tank determines the procedure.
  • Dry Spell: The dryer is an appliance (Energy hog No. 2), so keep it in top working order by regularly cleaning the lint screen clean and being smart about drying your clothes. Dry thick towels with other towels, for instance, rather than with light tee-shirts that will dry more quickly and use less energy. Don’t forget to clean the outdoor dryer vent, too.
  • Cold Water Wash: The biggest cost of washing clothes comes from the energy required to heat the water. Use cold water for most of your laundry load.

All Around the House:

  • Insulate Yourself: Having the right amount – and right type – of insulation will help your home retain the work your HVAC system does year round, but more than half of homes in the U.S. are not properly insulated. Climate determines both type and amount, so determine your needs, or call in a pro to help.
  • Location. Location. Location: Don’t place lamps, TV sets, or other heat producing appliances near your thermostat. The thermostat senses the heat causing the air conditioner (Energy hog No. 1) to run longer than necessary.
  • Be a Little Shady: Air conditioners with proper shading can be more efficient. Air in a shaded space is cooler than the surrounding air meaning the A/C will have an easier time cooling the air. Keep plants, shrubs, and other landscaping about two to four feet away from your outdoor unit to ensure adequate airflow.
  • Buyer’s Market: When buying new air conditioners, refrigerators or replacement windows, buy energy-efficient versions. They’re usually more expensive but federal tax credits and competition is helping bring prices down. You’ll save in the long-term.
  • Check all Corners: An energy auditor, maybe even your local power company, has expert and comprehensive advice on energy efficiency.
