Use Grid Forecast to plan energy use in Home on Apple Watch Ultra (U.S. only)
The electricity powering your home comes from different sources, which can include renewable energy, like solar and wind, or fossil fuels like coal and natural gas. The sources powering your home can change throughout the day. In the Home app 
on your Apple Watch Ultra you can see a forecast for your area that highlights cleaner (times that can help reduce carbon emissions) and less clean times to help you choose when to use electricity.
To view the Grid Forecast, you must be connected to the internet and location services must be turned on for the Home app on iPhone.
Note: Grid Forecast is available only in the contiguous U.S.; not available in Alaska or Hawaii.
Show Grid Forecast
Open the Home app on your Apple Watch Ultra.
Tap the Energy category to show the Grid Forecast.
Green bars in the widget indicate when cleaner energy is available in your area—from 4 p.m. until 10 p.m., for example. If there are no bars, cleaner energy isn’t forecast for the near future.
If you’re traveling, Grid Forecast shows energy information for both your home location, and the location of your paired iPhone.
You can also add the Grid Forecast complication to the watch face.
See Use Grid Forecast to plan energy use in Home on iPhone (U.S. only) in the iPhone User Guide.
