Microsoft Corp. is rolling out an energy-saving update to its Xbox gaming consoles intended to help the tech giant meet a 2030 deadline for its environmental goals. On Wednesday a subset of users, Xbox Insiders, will be automatically switched to a new energy-saving Shutdown option, Blaine Hauglie, technical program manager, wrote in a blog post. When left idle consoles will use less power than Sleep mode, which enables users to wake up devices and start gameplay more quickly. There are over a quarter of a million people in the Insider program, a group of gamers that get an early look at features and content in development.
