A new feature called Grid Forecast has been introduced in iOS 17, aiming to promote the use of clean energy based on a user's location. This feature is an extension of Apple's clean charging feature, which draws power from the grid when more renewable energy sources are available or overall usage is low. Grid Forecast helps predict the use and delivery of power to the electricity grid based on a user's location. It can assist in deciding when to charge an electric car or run a major appliance by highlighting times when the power in your home is 'cleaner'. Apple believes that using electricity during cleaner energy periods can help reduce carbon emissions. The Home app displays a graphical representation of the day's best charging times and includes an icon indicating if it's a good time to use more power. Grid Forecast is available on Mac, iPhone, iPad, and Apple Watch through the Home app and a widget that can be added to desktop or home screens. However, there are currently no automations linked to the feature, so users should check the Home app or widget before using a lot of electricity. The upcoming Matter specification release is expected to include device support, allowing users to schedule appliances like dryers or dishwashers based on the grid forecast. Apple's power monitoring features in the Home app have been lacking, with energy usage information only available in certain third-party apps. The company has emphasized the importance of reducing carbon emissions during its Wonderlust event, even creating a video featuring Octavia Spencer as Mother Nature.
