Your thermostat controls half your energy bill - more than appliances, more than electronics. So shouldn't it help you save energy?
The 3rd gen Nest Learning Thermostat does. It learns what temperature you like and builds a schedule around yours. Since 2011, the Nest Thermostat has saved over 8 billion kWh of energy in millions of homes worldwide.* And independent studies showed that it saved people an average of 10-12% on heating bills and 15% on cooling bills. So in under two years, it can pay for itself.
