A Google-funded data center is set to draw its power from a natural gas plant that emits millions of tons of carbon dioxide annually, according to documents reviewed by Wired, underscoring the environmental cost of the industry's surging demand for AI compute.
The disclosure arrives at an awkward moment for Google, which has publicly committed to operating on 24/7 carbon-free energy by 2030. The company's own sustainability reports have repeatedly cited renewable energy investment as central to its climate strategy. Yet the reliance on fossil fuel infrastructure to power new data centers points to a structural tension that Google shares with nearly every major player in the sector.
The gap between Big Tech's climate pledges and the fossil fuel infrastructure quietly powering its AI ambitions has never been more visible.
Why Gas Plants Are Becoming the Default for AI Infrastructure
The root cause is straightforward: AI workloads are extraordinarily energy-intensive, and demand is growing faster than renewable capacity can be built and connected to the grid. Training and running large language models requires sustained, uninterrupted power at a scale that wind and solar — both intermittent by nature — cannot reliably guarantee without significant battery storage or grid upgrades.
Natural gas plants, by contrast, can be brought online relatively quickly, offer dispatchable power around the clock, and sit closer to existing transmission infrastructure. For data center operators racing to meet customer demand for AI services, gas has become a common solution. According to Wired, this trend is increasingly common across the industry — not an isolated Google decision.
The human dimension here is not abstract. Communities located near large gas-fired power plants face elevated exposure to nitrogen oxides and particulate matter. A 2023 study by Harvard T.H. Chan School of Public Health (involving analysis of over 3,500 US power plants) found that fossil fuel air pollution accounts for significant premature mortality, with low-income and minority communities bearing a disproportionate burden. When a data center signs a long-term power agreement with a gas plant, it effectively extends that plant's operational life and its local health footprint.
The Credibility Gap in Tech's Climate Commitments
Google is not alone in navigating this contradiction. Microsoft announced in 2024 that its carbon emissions had risen 29% since 2020, attributing the increase directly to data center construction. Amazon Web Services similarly reported a rise in its carbon intensity metric as AI infrastructure investment accelerated. The pattern suggests that industry-wide net-zero pledges, however sincerely intended, were modelled on a pre-AI-boom energy trajectory that no longer reflects operational reality.
Energy analysts have pointed out that the accounting frameworks many tech companies use — such as purchasing renewable energy certificates (RECs) — allow firms to claim green credentials while physically consuming power from fossil fuel plants. RECs represent ownership of renewable generation somewhere on the grid, but they do not guarantee that the electrons flowing into a specific data center are carbon-free. Google's own 24/7 carbon-free energy standard is more stringent than RECs, requiring hour-by-hour matching of consumption with clean generation — but achieving that standard at scale, across all facilities, remains a work in progress.
What Regulators and Investors Are Watching
The Wired report is likely to attract attention from both regulators and ESG-focused investors. The US Securities and Exchange Commission's new climate disclosure rules — currently subject to legal challenge — would require large public companies to report Scope 1 and Scope 2 emissions more rigorously, making it harder to obscure the carbon footprint of specific facilities. In the European Union, the Corporate Sustainability Reporting Directive is already tightening disclosure requirements for companies operating in the bloc.
For investors applying environmental, social, and governance criteria, the core question is whether tech companies are making credible near-term progress or deferring the hard work of decarbonisation while benefiting from the reputational halo of long-dated climate pledges. A data center locked into a gas power agreement today could be drawing fossil fuel electricity well into the 2040s, depending on contract length and plant lifespan.
Google has not disputed the documents cited by Wired, according to the report. The company's position — consistent with others in the sector — is that bridging gas is a temporary measure while renewable and nuclear alternatives are developed and scaled. Small modular reactors (SMRs) have attracted particular interest from tech firms: Google signed an agreement with Kairos Power in 2024 to purchase SMR-generated electricity starting in the early 2030s, and Microsoft has backed the restart of the Three Mile Island nuclear facility.
Whether those alternatives arrive fast enough to matter — for the climate and for the communities living beside gas plants today — is the central question the industry has not yet answered convincingly.
What This Means
For anyone using AI-powered products today, this story is a direct reminder that the computational cost of those services is being paid, in part, in carbon emissions and local air quality — and that tech companies' climate timelines may be far more optimistic than their infrastructure decisions suggest.
