The Breakup
Meta has walked away from one of the biggest corporate clean energy clubs in the world. After ten years as a member, the company confirmed it is leaving the RE100 initiative - a group that asks big businesses to commit to 100% renewable electricity. Meta's spokesperson said the split was "mutual."
Meta's departure concludes a period during which the company increasingly relied on fossil fuels to run its artificial intelligence data centers. In the last 12 months, Meta has financed building no fewer than eleven gas-fired power facilities.
Last June, the company revealed plans for a 200 MW gas plant located behind its meter in Ohio, intended to supply a data center. Two months after that, Meta declared its intention to construct three sizable gas-fired power stations in Louisiana to provide power for its Hyperion data facility. Come April, Meta disclosed it would finance an additional seven gas power plants for that identical project. Together, these ten facilities will produce 7.5 GW of electricity, sufficient to supply all of South Dakota and more.

The Pollution Price Tag
Running data centers on natural gas 24/7 creates real environmental costs. For a single 1-gigawatt gas-powered data center, the numbers are striking. It releases 438 metric tons of nitrogen oxides per year.
Additionally, the plant emits 149 metric tons of fine particulates each year, particles small enough to lodge deep inside human lungs. Annually, the facility emits 298 metric tons of carbon monoxide and 61 metric tons of sulfur oxides.
Those are the kinds of figures that made RE100 take a closer look. The Climate Group, which administers RE100, recently revised its corporate guidance to require stricter reporting on advances toward renewable electricity targets. That change may have pushed Meta toward the exit.
Meta says it still plans to match its total data center electricity use "with 100% clean and renewable energy." But it plans to do that by purchasing environmental attribute certificates. This allows Meta to put money into a solar farm in one area while constructing a gas plant elsewhere; it then uses those certificates to assert the power is renewable, provided the solar farm generates sufficient electricity over a year to counterbalance the data center's consumption.
Other big tech companies are taking a different path. Microsoft, for example, is moving toward matching its electricity use on an hourly basis rather than annually. That approach pushes them to pair renewables with batteries instead of leaning on fossil fuels.
The AI Energy Dilemma
The massive power demands of artificial intelligence data centers are forcing tech companies to reconsider their energy strategies. Unlike traditional cloud workloads, AI servers run continuously at high utilization, requiring a steady baseload of electricity that renewables alone struggle to provide without storage. Natural gas plants offer a reliable, dispatchable power source that can meet these demands around the clock. This practical reality has led Meta and others to invest in gas-fired generation even as they maintain public commitments to clean energy.
