Google falling short of important climate target, cites electricity needs of AI

Credit: Unsplash/CC0 Public Domain Three years ago, Google set an ambitious plan to address climate change by going “net zero,” meaning it would release no more climate-changing gases into the air than it removes, by 2030. But a report from the company Tuesday shows it is nowhere near meeting that goal. Rather than declining, its […]

Hydrovolt to open battery recycling facility in France

Hydrovolt can take used batteries and turn them into a black powder from which it can recover the metals and make new batteries. Norwegian battery recycling firm Hydrovolt said Tuesday that it will expand internationally by opening a facility in France, boosting a nascent hub for producing electric vehicle batteries. The facility will open in […]
