#6 - Do you set back your thermostat?
Turning down the heat or air conditioning at night and while you are at work or using a programmable thermostat in your home can have significant savings.
According to the U.S. Department of Energy, you can save 5 percent to 15 percent per year on your heating/cooling bill by turning your thermostat back 10 to 15 degrees for eight hours. That is a savings of as much as 1 percent for each degree if the setback period is eight hours long. If your normal heating costs are $1,500 per year, that is a savings of $75 to $225 every year.
