1.Make Sure Your Home Is Sealed Properly. Once a year you should do a walk through with a caulk gun, and make sure their are no drafts coming in. 2.Don't Run The Dishwasher Until It Is A Full Load. 3.Use Compact Fluorescent Light Bulbs. They may cost a bit more than conventional bulbs, but they use a substantially less amount of energy, and last for years. They will easily pay for themselves and save you hundreds of dollars a year on your energy bill! 4.Install Light Dimmers. This is a great way to control the amount of electricity being used, based on the amount of light you need at a particular time. 5. Unplug Devices When They Are Not Being Used. Most devices will suck up energy while plugged in even if they are not being used (ie: cell phone chargers, blow dryers, radios, etc.). 6. Clean Or Change The Filter In Your Furnace Once A Month. Dust and dirt will make your unit much less efficient. Filters are very cheap, and having a clean one will save you lots of money. 7. Install A Programmable Thermostat. You can lower your heating and cooling costs by about 10% just by programming the thermostat to adjust itself during certain times of the day.

This will save you hundreds of dollars each year on your heating and cooling costs. And the cost for the materials and labor are tax deductible! 9. Take Showers Instead Of Baths. A bath uses many more gallons of water than a shower does. 10. Use Cold Water For Laundry. Their are cold water detergents on the market that will get your clothes as clean as they would be if you had used hot water, but will save you money on your energy bill!
