Arriving with iOS 17, a new feature called "Grid Forecast" in the Apple Home app will show users when their electrical grid has relatively clean or less clean energy sources available.

"For example, there are times when wind and solar projects produce more energy than the grid can use, leading to some of it being wasted. There are also times when electricity is being generated with lower emissions. By using electricity during these cleaner times, customers may lower the climate impact of the electricity they use at home," Apple explained.
