Google reported that its annual electricity consumption rose 37 percent in 2025—the largest year-on-year increase in the company's history, driven by accelerating AI data center construction and operations. Despite the surge, the tech giant reduced operational carbon emissions by 2 percent through continued purchases of clean energy.

Google's data centers consumed 42 million megawatt-hours of electricity in 2025, compared to 30.6 million megawatt-hours in 2024, according to the company's sustainability report.
