A new update for Xbox consoles will make them "carbon aware" - reducing the carbon footprint by optimising updates and download times to when the most renewable energy in local energy grids can be used.The feature will be available for Xbox Insiders using the energy saving shutdown power option and with their console configured to support automatic updates.Microsoft claims that for every two Xbox consoles switching to shutdown mode, it will save the carbon equivalent of one tree planted and grown for a decade - based on an average of Xbox consoles on shutdown for 20 hours each day for a year.A further energy setting for Insiders is the "Active hours" setting, in which users using the sleep power option can adjust the console's active hours where it will boot quickly and be available for remote waking.Enjoy ad-free browsing, merch discounts, our monthly letter from the editor, and show your support with a supporter-exclusive comment flair!"
