Meta has left RE100, a corporate renewable energy group, after spending the past year funding natural gas plants for its artificial intelligence operations, TechCrunch reported on July 23. Meta had belonged to the initiative, which centers on companies working toward 100% renewable electricity, for about a decade, and a spokesperson said the split was mutual. To support its AI data centers, Meta has backed numerous gas plants, including a 200-megawatt facility in Ohio and 10 plants connected to its Hyperion project in Louisiana, which are expected to deliver 7.5 gigawatts of electricity. Despite this, Meta told TechCrunch it was still committed to matching its data center electricity use "with 100% clean and renewable energy." RE100 has recently tightened its reporting expectations for members, after Meta had previously told the group it would "run its entire operations on renewable electricity by 2020." TechCrunch reported that a gas-powered 1-gigawatt data center running nonstop could emit roughly 483 tons of nitrogen oxides, 164 tons of fine particulate matter, 67 tons of sulfur oxides, and 328 tons of carbon monoxide.
