Microsoft is considering pushing back or even dropping one of its key clean energy goals for 2030, as it rapidly expands data centers to meet growing demand for AI and cloud computing, according to people familiar with the matter speaking to Bloomberg.
The initiative in question, unveiled in 2021 and labeled “100/100/0,” calls for Microsoft to cover 100% of its electricity consumption—every hour of every day—with clean, zero-carbon energy sourced from the same power grids where it operates. Unlike simpler annual offset models that merely balance total yearly usage with renewable purchases, this target demands real-time alignment between energy draw and carbon-free supply.
Microsoft has already achieved its less stringent annual renewable matching goal, the report notes. However, leadership is now debating whether the stricter hourly zero-carbon commitment remains feasible amid surging investments in AI infrastructure.
Discussions are still underway, and no official decision has been reached. A company spokesperson emphasized Microsoft’s continued pursuit of annual matching but declined to comment directly on the status of the hourly target.
As part of its broader energy strategy, Microsoft recently highlighted agreements such as one with We Energies to develop 1.2 gigawatts of carbon-free projects in Wisconsin—including solar farms and battery storage systems scheduled to come online starting December 2028.
Growing AI operations drive energy use upward
Alongside Amazon, Alphabet, and Meta, Microsoft is pouring billions into data center construction to support AI tools like Azure and Copilot. This expansion is reflected in its latest environmental disclosures. In its 2025 Sustainability Report, Microsoft revealed that its combined Scope 1, 2, and 3 emissions rose 23.4% above its 2020 baseline, with “AI and cloud growth” cited as a primary driver.
Over the same period, the company’s total energy consumption surged by 168%, far outpacing its 71% revenue increase.
This trend isn’t unique to Microsoft. All four tech giants have seen emissions climb since ChatGPT launched in late 2022: Meta up 64%, Google 51%, Amazon 33%, and Microsoft 23%.
Some upcoming data center developments are projected to require multiple gigawatts of power—enough to supply electricity to hundreds of thousands of U.S. homes. Microsoft, for instance, is reportedly adding roughly one gigawatt of capacity every three months.
Soaring electricity demand reshapes power planning
BloombergNEF forecasts that U.S. data center power demand will jump from 34.7 gigawatts in 2024 to a staggering 106 gigawatts by 2035. Globally, the International Energy Agency expects data center electricity use to nearly double—from 485 terawatt-hours (TWh) in 2025 to 950 TWh by 2030.
To secure reliable power, Microsoft has explored diverse energy sources. In 2024, it signed a landmark deal with Constellation Energy to revive a unit at Pennsylvania’s Three Mile Island nuclear plant, directly linking that output to its AI and cloud workloads.
Natural gas is also playing a role. The report notes Microsoft held talks with Chevron this year to help fund a large gas-fired power plant in Texas’s Permian Basin region.
Additionally, over 20 gigawatts of behind-the-meter power projects—generation built on-site or directly connected to customers rather than fed through the main grid—were announced for data centers in Texas between 2024 and mid-2025, with another 10GW added in early 2026, according to Reuters. These often pair gas turbines with batteries or renewables to ensure stable, high-capacity supply. BloombergNEF has tracked 4.9 gigawatts of such hybrid setups.
Heightened scrutiny on clean tech spending
Microsoft expects to invest up to $190 billion by year-end, mostly on data centers, the report states. This massive outlay has tightened budgets across many internal divisions—including sustainability teams focused on decarbonization.
Clean energy initiatives are now subject to more rigorous financial review as AI infrastructure takes priority. Bloomberg also reported that Microsoft scaled back parts of its carbon dioxide removal efforts, sparking concern in the voluntary carbon market.
Despite these shifts, Microsoft has not officially altered or abandoned its 2030 clean energy target.
