We invented the Smart Thermostat and kicked off a wave of innovation that has changed the way millions of people heat and cool their homes. That was just the beginning. Our smart thermostats save their owners up to 26%* on heating and cooling and offer even bigger savings for the planet.ecobee Smart Owners have saved the equivalent of 27.8 TWh of electricity, which is like taking all the homes in LA and Chicago off the grid for one year. By heating homes more efficiently, ecobee thermostats have kept 5.1 million tons of CO2e out of the atmosphere.** That’s like removing 1.1 million cars from the road for a year. We keep thousands of our thermostats out of landfills and reduce e-waste by repairing and reusing them. The average household in the United States produces 7.5 tons of CO2 per year and over half of the energy used in most homes is for heating and cooling.³ Our ENERGY STAR certified smart thermostats and sensors have been invited into millions of homes because they guarantee lower energy costs by up to 26%* percent. That translates into an average annual saving of $234 per home? and billions of kWh of energy savings for ecobee users.
