Google’s latest sustainability report reveals a massive rise in electricity consumption, largely driven by its data center operations. In 2024 alone, Google used 30.8 million megawatt-hours of electricity, more than double the 14.4 million megawatt-hours it consumed in 2020.
A whopping 95.8% of Google’s electricity consumption in 2024 came from its data centers, according to the report. This trend has held steady over the past four years, with minimal energy usage attributed to the company’s non-data-center operations. By extrapolating historical data, analysts estimate that Google’s data centers consumed just over 4 million MWh in 2014, a sevenfold increase in the last decade.
Despite leading the industry in energy efficiency, Google’s improvements are plateauing. Its 2024 power usage effectiveness (PUE) dropped only slightly to 1.09, down from 1.10 in 2023. That’s just a 0.02 improvement over ten years, signaling diminishing returns of current optimization strategies.
Google recently inked a deal with Commonwealth Fusion Systems to buy 200 megawatts of fusion power once it becomes viable. Fusion remains years away from commercial deployment, but the move shows Google’s push to secure clean, scalable energy sources to fuel its growing infrastructure needs.
