Summary
42 million megawatt-hours of power use in 2025 marked Google’s biggest annual increase on record, with data centers alone rising from 30.6 million MWh a year earlier.
AI infrastructure expansion drove the surge, alongside growth in Google Cloud, YouTube streaming, and construction and operation of data centers supporting AI products and services.
Google said operational carbon emissions still fell 2% in 2025 because it kept buying large amounts of clean energy, even as power demand outpaced grid decarbonization.
Since 2019, Google’s total electricity consumption has climbed more than 250%, underscoring how AI growth is straining efforts to meet its longer-term climate goals.
