In the iOS 17 RC and watchOS 10 RC versions released yesterday, Apple introduced the “Power Grid Prediction” function in the Home application, which tells users what to use based on their location. Hours of supply with “clean” energy, thereby reducing your carbon footprint.
Attached the content of Apple’s official update log as follows:
Grid Forecast is a new feature introduced by Apple in the Home app that aims to show users times when the grid is providing relatively clean and relatively unclean energy.

For example, there are periods when wind and solar projects generate more electricity than the grid can use, causing some energy to be wasted.
During certain periods, the carbon emissions from electricity generation may be lower. By using electricity during times when the energy source is cleaner, users can reduce the climate impact of household electricity use.

Apple aggregates data on the power grid, greenhouse gas emissions and weather information into an easy-to-track signal. This could help people decide the best time of day to run large appliances and charge electric cars or devices.
Grid forecasting is available through the Home app on iPhone, iPad, Mac and Apple Watch, and can also be added as an iOS widget or complication on the watch face.


Apple is obtaining more data through industry cooperation and will continue to improve power grid forecasting in order to play a greater role.
