Nest Renew is Google's program to shift when your home uses electricity to match times when cleaner energy is available
Nest Renew is a service that works with your Google Nest thermostat to automatically adjust when your heating and cooling runs. Instead of heating or cooling whenever your home needs it, Nest Renew tries to time those adjustments for hours when your power grid is using more renewable energy like wind or solar. The goal is to reduce the carbon footprint of your home's energy use, not to lower your bill — though in some cases it may help.
The program works only if you have a compatible Nest thermostat (the Nest Learning Thermostat or Nest Thermostat with Voice Control), live in a region where Google has partnered with the local utility, and you turn the feature on in your Nest app. Google does not charge you to use Nest Renew itself, but your utility company may offer a rebate or credit if you enroll.
Key Takeaways
- Nest Renew automatically shifts your heating and cooling to times when your grid has more renewable energy available, which you control through your Nest app.
- The feature only works in certain regions where Google has partnerships with local utilities, so you may not have access even if you own a compatible thermostat.
- Nest Renew does not lower your total energy use — it changes when you use energy, so your bill may stay the same or shift slightly depending on your utility's pricing.
- Some utilities offer rebates or bill credits for enrolling in Nest Renew, so check with your power company to see what incentives are available in your area.
How Nest Renew actually works on your thermostat
When Nest Renew is active, Google's system looks at real-time data about your power grid's energy mix — what percentage is coming from wind, solar, hydroelectric, and other renewable sources versus fossil fuels. Your thermostat then makes small adjustments to when it heats or cools your home to align with the times when that renewable percentage is highest.
For example, if your grid is expected to have a lot of solar power available between 10 a.m. and 2 p.m., Nest Renew might cool your home a bit more during those hours so it stays comfortable later when renewable energy is scarce. You set a comfort range in your Nest app — say 68 to 72 degrees — and the thermostat stays within that range while shifting the timing of when it actually runs the heating or cooling equipment.
The adjustments are usually small enough that you do not notice them. If the system cannot keep your home in your comfort range while waiting for cleaner energy, it will heat or cool when ready regardless of the grid's energy mix. Your comfort always comes first.
Where Nest Renew is available and how to check
Nest Renew is not available everywhere. Google has partnerships with specific utilities in certain regions, and the feature only works if your home gets power from one of those utilities. As of now, the program operates in parts of California, Colorado, Texas, and a few other states, but coverage is expanding slowly.
To learn about Nest Renew is available at your address, open your Nest app, go to Settings, and look for the Nest Renew option. If it appears and is not grayed out, your utility participates. If you do not see it at all, your region is not yet covered. You can also contact your utility company directly to ask whether they have partnered with Google for this program.
The difference between Nest Renew and other energy-saving features
Nest Renew is different from the basic energy-saving features that come with most smart thermostats. A standard Nest thermostat learns your schedule and adjusts temperature to save energy when you are away or asleep. Nest Renew does not focus on when you are home — it focuses on when your grid has clean energy available.
You can use both at the same time. Your thermostat might lower the temperature when you leave for work (standard feature) and then shift when it reheats your home based on grid conditions (Nest Renew). The two work together rather than competing.
Other utilities offer their own demand-response programs that do something similar — they ask customers to reduce energy use during peak hours in exchange for a lower rate or a credit. Nest Renew is Google's version of this idea, built into your thermostat so it happens automatically without you having to remember to adjust anything.
What Nest Renew costs and what incentives may be available
Google does not charge you a subscription fee to use Nest Renew. The feature is included free with compatible Nest thermostats if your utility participates in the program.
However, your utility may offer a rebate, bill credit, or other incentive for enrolling. Some utilities credit your account a small amount each month you have Nest Renew active. Others offer a one-time rebate when you first enroll. The amount and terms vary widely by utility, so contact your power company to ask what they offer. You may need to enroll through your utility's website or app to receive the incentive, even though the thermostat feature itself is free.
Keep in mind that Nest Renew does not reduce your total energy consumption — it shifts when you use energy. If your utility charges the same rate all day, Nest Renew will not lower your bill. If your utility charges higher rates during peak hours, Nest Renew might reduce your bill slightly by shifting some use to cheaper hours, but the savings are usually modest.
Privacy and data: what Google collects when you use Nest Renew
When Nest Renew is active, Google collects data about your home's temperature, when your heating and cooling system runs, and how your thermostat responds to grid conditions. This data helps Google improve the Nest Renew algorithm and understand how well the program works across different homes and climates.
Google says this data is tied to your Google account and is subject to Google's privacy policy. You can turn off Nest Renew at any time through your Nest app, which stops the data collection related to the program. Your basic thermostat data — temperature readings and schedule — continues to be collected as long as your thermostat is connected to the internet, whether or not Nest Renew is active.
If you are uncomfortable with Google collecting this data, you can straightforward leave Nest Renew turned off. The thermostat will still work normally for heating and cooling; you just will not participate in the grid-balancing program.
Whether Nest Renew makes sense for your home
Nest Renew is worth turning on if you care about reducing the carbon footprint of your energy use and your utility participates in the program. The feature requires no action from you once it is set up — it works automatically in the background. If your utility offers a rebate or credit, that is an added reason to enroll.
Nest Renew is not a tool for lowering your energy bill significantly. If your main goal is to reduce your heating and cooling costs, focus instead on basic thermostat features like scheduling, away mode, and setting a narrower comfort range. Those changes will have a much larger effect on your bill than Nest Renew will.
If you live in a region where Nest Renew is not available, you cannot use it no matter what you do. The feature depends on Google's partnerships with specific utilities, and those partnerships are limited. Check back periodically to see if your utility has joined the program.
Frequently Asked Questions
Will Nest Renew make my home uncomfortable?
Nest Renew makes small adjustments within the comfort range you set in your app. If the system cannot keep your home in that range while waiting for cleaner energy, it will heat or cool when ready. You control the comfort range, so you can set it as narrow or wide as you prefer.
Can I use Nest Renew if I rent my home?
Yes, as long as you own or control the thermostat. If your landlord owns the thermostat or your lease forbids you from replacing it, you cannot install a Nest thermostat yourself. Check your lease and talk to your landlord before purchasing one.
Does Nest Renew work with other smart home systems?
Nest Renew is built into Google Nest thermostats and works with other Google Home devices if you want to check your thermostat status through voice commands. It does not integrate with other brands' smart home systems like Amazon Alexa or Apple HomeKit.
What happens to Nest Renew if my internet goes out?
Your thermostat will continue to heat and cool your home normally, but Nest Renew will not work because it needs real-time grid data from Google's servers. Once your internet is back, Nest Renew will resume automatically.
How much money can I save with Nest Renew?
Savings depend entirely on your utility's pricing structure and how much your thermostat can shift energy use to cheaper hours. Most homes see little to no bill reduction from Nest Renew alone. The main benefit is reducing carbon emissions, not lowering costs.
