SILICON VALLEY — Google's annual electricity consumption increased by 37 percent in 2025, marking the largest annual rise in the company's history. The company attributed this surge to growth in Google Cloud, YouTube video streaming, and the construction and operation of data centers supporting artificial intelligence products and services.

Google's data centers consumed more than 42 million megawatt-hours of electricity in 2025, compared to 30.6 million megawatt-hours in 2024. This reflects an increase of more than 250 percent in total electricity usage since 2019.

Between 2024 and 2025, Google's total ambition-based emissions increased by 18 percent. The company's overall carbon footprint for 2025 was approximately 14.5 million metric tons of carbon dioxide equivalent. Google reported a 2 percent reduction in its operational emissions in 2025 compared to 2024. However, the company's supply chain emissions, originating from contracted manufacturers and suppliers, grew by 25 percent in 2025. Google attributed this growth to an Asia-Pacific supply chain operating on grids with insufficient carbon-free energy.

A Google spokesperson stated, "While the path to achieving our climate ambitions will not be linear—given our AI infrastructure buildout is currently accelerating faster than the grid is decarbonizing—we remain focused on scaling abundant and affordable clean power globally and progressing technological innovations that drive down emissions across our operations and the broader industry."

In 2025, Google entered into purchase agreements for 12 gigawatts of net-new clean energy, the largest annual total in the company's history for such agreements. Between 2010 and 2025, Google invested more than $3.8 billion in clean energy technology, which is expected to bring 7.5 gigawatts of clean energy online.
