There's more to your home's power and energy than flipping a switch. If you have a smart thermostat, you can sign up for demand response programs through your local utility company. These programs slightly adjust your AC or furnace usage when there's high demand in the community, like on extra hot days when everyone is trying to cool their home. This small adjustment helps to prevent utility grids being overloaded and people losing power. These programs can also save you money by reducing your home's energy usage.
