Saving energy starts with your thermostat.
Nest thermostats use smarts to help you save.
Turning off the lights. Installing efficient appliances. These actions can save energy, but there’s an even better place to start your energy-saving efforts: at the thermostat.
On average, more than half of a US household’s energy consumption is for just two uses: heating and cooling.1 This means that a thermostat can really make an impact on your home’s energy use, and reduce your overall energy bill.
It seems simple, but one of the best and least used tools for energy savings is programming your thermostat. But many programmable thermostats are just set to stay at one temperature all the time.

In many households, a lot of energy is wasted heating or cooling the home when nobody’s there. If you opt in, Nest thermostats can use sensors and your phone’s location to determine whether you’ve left the house. Then, your thermostat can set itself to an
The Leaf icon appears on your Nest thermostat or in the app to signal that you’ve made an adjustment to a more energy-efficient temperature.3 The Leaf encourages you to choose energy-saving temperatures that are a little higher or lower than what you’ve set in the past, all in the name of energy and cost savings.
Nest thermostats are also smart about when to use energy, thanks to Rush Hour Rewards. Just as traffic clogs up roads when everyone drives to work at the same time, energy rush hours occur when a lot of people in a particular area turn on air conditioning or heating at once. With Rush Hour Rewards, you can earn rewards from your energy company by using less energy
Nest Learning Thermostat (4th gen)
Save energy, brilliantly.
Many smart thermostat brands estimate savings by comparing to a thermostat set to 72° F 24/7 all year long. This can often result in higher savings estimates. Instead, Nest calculates savings using a more rigorous approach based on real data.
In 2015, we reviewed the energy bills of real people in real homes across 41 US states before and after installing the Nest Learning Thermostat. We watched the data roll in from two independent studies and the results were clear: on average, the Nest Learning Thermostat saved an average of 12% on heating bills and 15% on cooling bills.7 Read more in our

So it’s simple. Nest thermostats can help you save.

Since then, all the other Nest thermostats have been ENERGY STAR® certified, too.
The kilowatt-hour (kWh) ticker features an estimate of how many
These energy savings are calculated based on the typical percentage of heating and cooling savings found in real-world studies of Nest Thermostats. To calculate the total savings, we apply these savings percentages to the actual heating and cooling hours of all Nest thermostats in use during the period.
Nest thermostats can help keep your home cool in summer and warm in winter, just as you like – with many ways to increase your savings.
