Tech companies report higher electricity use from AI

Google, Microsoft and Amazon each released sustainability reports in recent weeks that showed higher electricity consumption tied to AI operations. The reports also noted efficiency gains in energy and water use. Those gains were exceeded by overall growth in demand. Google's electricity consumption rose more than 140% between 2021 and 2025.

Scale of demand The combined new electricity demand added by Google, Microsoft, Amazon and Meta from 2022 to 2025 is roughly twice New York City's annual electricity consumption, according to estimates cited in the reports.

Company statements "We are deeply committed to responsibly managing the environmental footprint of our operations," said Google's chief sustainability officer. "Our goal is not simply to slow the growth of environmental impacts," said Microsoft's chief sustainability officer.

AI industry has operated on the assumption that greater scale leads to better performance and profits, according to a research and advisory firm focused on AI's environmental impacts. The potential for AI to improve lives and reduce emissions is also appearing more often in company sustainability messaging.

Google devoted more space in this year's report to AI applications such as autonomous vehicles and scaling solar power. Many of the highlighted applications rely on narrower models rather than the frontier models driving data-center growth, according to the same research firm.

Environmental concerns may affect the industry most through economic consequences, according to an MIT economics professor and Nobel laureate. "The argument from the industry insiders is 'Just wait — the next two, three, four years are going to be different,'" the professor said.
