Saving energy starts with your thermostat.

Putting in new light bulbs. Efficient appliances. Unplugging everything when you leave. It saves energy, sure. But it’s a drop in the bucket compared to what a thermostat can do. Your thermostat controls half your energy bill. And it’s wasting energy.

Programming isn’t proven.

Programmable thermostats claim savings on your energy bill. But they can’t prove it. They make you punch in every temperature change you want throughout the day, and usually you can only program 2 or 3 changes. It’s annoying and complicated – most people don’t even bother. So despite their claims, most programmed thermostats stay at the same temperature all day. And that wastes energy. Programming just doesn’t work. So Nest found a better way. And a whole new way: it learns.

It saves energy.
And here’s the proof.

Because the Nest Thermostat learns how and when to keep you comfortable, it knows how and when to save energy. To prove it, we looked at the energy bills of real people in 41 states before and after they got Nest Thermostats. Then we watched the data roll in from two independent studies – from real homes with real families and real thermostats. The results were clear: on average the Nest Thermostat saved 10% to 12% on heating and 15% on cooling. Based on typical energy costs, we’ve estimated average savings of $131 to $145 a year. That means the Nest Thermostat paid for itself in under two years.

In February 2017, the Nest Thermostat became the first thermostat to get ENERGY STAR certified by the EPA.
Their rigorous testing confirmed what we’ve been saying all along – the Nest Thermostat saves energy.

Even more savings all year round.

That’s not the only study to show Nest’s energy savings are real. Check out what we learned about Seasonal Savings and Rush Hour Rewards, two programs offered by our energy partners. Learn more >

Seasonal Savings

The Nest Thermostat fine-tunes your schedule as the seasons change to help you save. We've seen Nest users save 5-10% with their new schedules.

Rush Hour Rewards

You can earn rewards from your energy company by using less energy when everyone else is using more. Like on hot summer days when everyone’s running the AC at the same time.

Nest kWh Ticker

Nest’s kilowatt-hours (kWh) ticker features an estimate of how many kilowatt-hours all Nest Learning Thermostats have saved to date, since October 2011.

These energy savings are calculated based on the typical percentage of heating and cooling savings found in real-world studies of the Nest Learning Thermostat (download the energy savings research in PDF format). To calculate the total savings, we apply these savings percentages to the actual heating and cooling hours of all Nest Thermostats.

For Nest’s kWh ticker, we calculate the current savings estimate from the total savings estimate at the end of the prior month, and increase that number going forward using the average rate of savings from the same month of last year (adjusting that rate downward by 25% to be conservative).

Energy savings are an estimate, not a guarantee that any individual user will save energy.
