Smart Savers Initiative FAQs

Energy efficiency is easy when you have a smart thermostat installed at home. The average home spends around $2,200 a year on utility bills, with about half of that being heating and cooling. With the help of a smart thermostat, you could save up to $180 per year in energy costs when using the eco settings.
