Raising the thermosat isn't the most economical or healthy way to keep your home warm this winter. Electric power plants are the country's largest industrial source of pollutants. By snuggling under a blanket on the couch during these frigid days instead of turning up the heat you can save pounds of pollution, as well as some money off your utility bills.
Set your thermostat in winter to 68° F (20° C) or less during the daytime and 55° F (13° C) before going to sleep or when you are away for the day. If you are a bit chilly, grab a sweater or an extra blanket instead of turning up the heat. During cold weather, let the sun shine in when possible. Insulate your windows with heavy curtains and use weather stripping around doors. You will notice the difference in many ways!
