US and UK Strain Resources as AI Data Centers Surge

Extreme heat waves in the United States and United Kingdom have triggered a resource crisis as the rapid growth of AI infrastructure strains power grids and water supplies. In the U.S. Mid-Atlantic region, Chris Wright, the U.S. Secretary of Energy, directed data centers and large electricity customers to switch to backup power supplies to prevent residential blackouts. This emergency measure, coordinated with PJM Interconnection, was enacted after demand nearly surpassed a 2006 record, reaching approximately 166,147 megawatts on July 2.

The shift to backup diesel and gas generators has raised environmental and health concerns due to increased local pollution. Simultaneously, New York City experienced outages affecting over 15,000 customers, leading Mayor Zohran Mamdani to urge residents to conserve electricity.

In the United Kingdom, the Environment Agency warned that hybrid cooling systems in data centers cause seasonal spikes in water demand, threatening water-stressed regions including London and Southeast England. While TechUK claims commercial data centers are not intensive water users, legislative bodies warn that future demand will pressure critical resources.

Globally, the AI-driven electricity crisis is stalling expansion. A $1 billion Microsoft project in Kenya has stalled, and analysts estimate that over half of announced U.S. data centers for 2026 may be cancelled due to power shortages. In response, companies like Amazon Web Services and Bitzero are pursuing dedicated nuclear and hydroelectric assets to bypass unstable grids.
