Meta has made significant investments in natural gas over the past year. Now it's dropping out of an industry renewable energy group.

Over the past year, Meta has funded the construction of at least a dozen natural gas power plants, including one project that alone will burn enough natural gas to generate as much electricity as the entire state of South Dakota uses. Now Meta is no longer part of the RE100, a corporate renewable energy initiative, after a decade of membership, the company confirmed to TechCrunch today. The breakup was mutual, according to a Meta spokesperson. The exit caps months of Meta expanding its bet on fossil fuels to power its AI data centers and begs the obvious question: What does “clean energy” actually mean to a company that keeps building gas plants while still calling itself renewable? RE100 is a project of the Climate Group, a U.K.-headquartered nonprofit co-founded by former prime minister Tony Blair. The initiative provides policy and technical support to corporations seeking to transition to 100% renewable energy. Meta competitors Apple, Google, and Microsoft remain among the group’s 444 members. Recharge News was first to report Meta’s departure. While Meta wouldn’t comment on the reasons behind the departure —and the Climate Group did not reply to TechCrunch’s inquiry — the nonprofit recently updated its guidance for companies, enforcing more rigorous reporting on progress toward renewable energy goals. Previously, Meta told RE100 that it would “run its entire operations on renewable electricity by 2020.” Like many tech companies, Meta’s embrace of AI has pushed it to secure large amounts of power for its data centers, and while the company continues to procure renewable energy, it has embraced natural gas like few others. Meta’s toe in the water was a 200-megawatt behind-the-meter gas power plant in Ohio, announced in June of last year, that will power one of its data centers. Two months later, Meta said it would build three large natural gas power plants in Louisiana to supply electricity to its Hyperion data center. Then in April, the company announced that it would fund seven more natural gas power plants for the same project. Combined, the 10 power plants will generate 7.5 gigawatts, enough electricity to power South Dakota and then some.
