It seems easy enough, right? Lower your heating bill by turning down the heat.
We're not suggesting you maintain an arctic climate inside your house. Simply keep your thermostat at about 68 degrees Fahrenheit during the day and if you're cold, reach for a sweater. For each additional degree you lower the temperature (in the 60- to 70-degree Fahrenheit range) you continue to save cash — up to 5 percent on your heating bill.
Bonus savings: Install a smart thermostat that you can program to adjust the temperature while you're away or while you sleep. The Environmental Protection Agency estimates you'll save $180 on your annual energy bills this way.
