AI Data Centers Threaten Big Tech Climate Goals as Fossil Fuel Use Surges
Fortune reports that AI model training is straining data center power consumption, with natural gas supplying over 40% of U.S. data center electricity and coal 30% globally, jeopardizing big tech's climate commitments.
Key Points
- Natural gas supplied over 40% of U.S. data center electricity in 2024
- Coal supplied 30% of global data center power
- Backlog of renewable energy projects awaiting grid connection
- Tech companies' climate goals hinged on renewable energy credits now at risk
Full Details
A Fortune report published on March 29, 2026 reveals that the surge in AI model training is significantly straining data center power consumption, threatening big tech's previously announced climate goals. According to the International Energy Agency, natural gas accounted for more than 40% of electricity powering U.S. data centers in 2024, while coal supplied 30% globally. Many tech companies set ambitious renewable energy goals expecting federal tax credits to support wind and solar deployment, but a backlog of proposed projects awaiting grid connection permission and Trump administration policies sideline renewables. Experts note that companies in 2020 could not have projected current energy needs since the technology and equipment for training machine learning models—which consume most data center electricity—were just being introduced. This fossil fuel reliance jeopardizes climate commitments that had previously hinged on renewable energy credits.
Why It Matters
The tension between AI advancement and climate commitments may force tech companies to make difficult tradeoffs, potentially slowing AI development or requiring massive investments in on-site renewable generation and nuclear power.
