Google's electricity use jumped 37 percent in 2025, the largest single-year rise in the company's history, as the build-out of artificial-intelligence infrastructure crossed from pilot to core business. For nine consecutive years Google had met its climate goal with a simple arithmetic trick: buy enough renewable-energy certificates to match the total electricity it consumed over a year. In the 2026 Environmental Report and an accompanying company blog post, the company now says that arithmetic is no longer adequate, and is staking credibility on a more demanding ledger: matching consumption to clean generation hour by hour, on the grid where each data center actually runs.
That shift has a name. Google calls it "24/7 carbon-free energy," a method that tracks whether the megawatt-hours pulling into a campus are matched by clean megawatt-hours on the same regional grid in the same hour, rather than paper-traded certificates sourced from anywhere on the planet. The distinction matters because an annual purchase can certify a wind farm in West Texas while a campus runs on a coal-heavy grid in West Virginia; the certificate is correct, the climate signal is not. Data Center Knowledge's coverage of Google's disclosure lays out the gap in plain terms: the company's clean-energy claims have technically held, while the grids where its AI workloads now run have not kept up.
The first public scorecard is in Texas. Google has committed roughly $40 billion to a data-center complex whose on-site power plan is still being written. A 933-megawatt natural-gas plant proposed for the campus could emit as much as 4.5 million tons of carbon dioxide a year if built without carbon capture and storage, the technology that scrubs CO2 from exhaust streams before it reaches the atmosphere. Google's spokesperson has confirmed the campus is being explored but has not signed an offtake agreement committing the company to buy power from the plant, according to Ars Technica, which first reported the figures in early July 2026. Whether Google ends up taking that power, or instead waits for clean capacity that meets the 24/7 test, will determine whether the new accounting is a discipline the company imposes on itself or a slogan it routes around.
Data Center Dynamics reported that the 37 percent jump is by far the largest annual increase in Google's history; prior year-over-year rises sat in the high teens, and the company has roughly doubled its electricity demand in three years. The growth tracks the operational reality that AI training and inference workloads consume far more power than the search, email, and video products Google historically ran. The company's Environmental Report PDF ties the increase directly to AI infrastructure as the primary driver.
The pivot to 24/7 matching is paired with the largest private portfolio of next-generation power projects the company has assembled. In 2025 Google signed power-purchase agreements for 12 gigawatts of net-new clean energy, the largest annual total it has ever contracted, and has spent more than $3.8 billion on clean-energy projects since 2010, a sum expected to bring roughly 7.5 gigawatts online. The technology mix is unusually broad for a single corporate buyer: advanced nuclear, experimental fusion, enhanced geothermal, long-duration storage, and natural gas only when paired with carbon capture and storage. Cleanview, an independent data-center power analyst, characterizes the strategy in its Google power report as "Everything Everywhere All at Once," which its CEO Michael Thomas frames as a recognition that no single clean source is yet ready to carry a hyperscale AI workload. Each of those bets resolves on a different timeline; fusion remains a science project, geothermal is moving from pilot to commercial scale, and small modular reactors are still years from first concrete pours.
One disclosure complicates the picture and is worth naming rather than burying. Google's contracted-manufacturer supply-chain emissions rose 25 percent in 2025, an increase the company attributes to component suppliers operating in Asia-Pacific regions whose grids are not yet running on clean power. The same 24/7 logic that pushes Google to scrutinize its own campus grids applies, in principle, to the grids where its hardware is built. Whether Google extends that scrutiny as a contractual requirement on suppliers, or treats it as a longer-term advocacy problem, is one of the open questions for the next reporting cycle.
What to watch next: whether the Texas data-center campus signs any power-purchase agreement at all before the 24/7 carbon-free reporting year ends, and whether the Federal Energy Regulatory Commission's recent targeted action to speed large-load interconnection creates a faster lane for the clean-energy projects Google wants to bring online. The EPA's eGRID database, which scores carbon intensity by regional grid, will be the reference point outsiders use to score Google's hourly accounting against the actual emissions profile of each grid it operates on. The numbers Google publishes next year on Texas and on Asia-Pacific supplier grids will be the first honest read on whether the harder promise holds.
