Insulate Water Heater

If your electric water heater was built before 2004, it would be a good idea to have added insulation. Wrap it in an insulating jacket such as a Thermwell blanket. You'll save 10%- about $30 annually on your water-heating bill.

Use Cold Water Wash

You can save 50% of the energy you would otherwise use for hot water just by using cold water in your washer. Set your dryer on the moisture sensor, not the timer, and you could cut your energy use by 15%.
