Google's electricity consumption jumped 37% in 2025 to over 48 TWh, driven entirely by AI data center demands. The company is investing in nuclear and grid-scale batteries to meet its 2030 carbon-free energy goals despite the AI boom.
Google's electricity consumption surged 37% year-over-year in 2025, driven overwhelmingly by the rapid expansion of its AI data center infrastructure, the company disclosed in its latest environmental report.
The report reveals that Google consumed over 48 terawatt-hours of electricity in 2025 — equivalent to the annual power consumption of a small European country. The growth was almost entirely attributed to the energy demands of training and running large language models and other AI workloads.
“Our increasing AI compute needs are placing unprecedented demands on our data center infrastructure and the broader grid.”
— Kate Brandt, Google Chief Sustainability Officer
Warning
Despite the surge, Google maintains its 24/7 carbon-free energy goal for 2030, though this report acknowledges the AI boom makes that target increasingly challenging.
In response, Google has accelerated investments in next-generation nuclear power, grid-scale batteries, and demand-response systems to manage the growing energy burden.
| Energy Source | 2024 Share | 2025 Share |
|---|---|---|
| Wind | 29% | 26% |
| Solar | 24% | 28% |
| Nuclear (PPAs) | 8% | 12% |
| Other renewables | 18% | 15% |
Key Takeaways
- 1 Google's electricity use rose 37% year-over-year to over 48 TWh in 2025
- 2 AI workloads — particularly LLM training and inference — are the primary driver
- 3 Google is increasing investments in nuclear and battery storage
- 4 The 2030 carbon-free energy goal is becoming harder to achieve due to AI growth
Frequently Asked Questions
