Data Centers Now Consume 6% of UK and US Electricity
IDCA report warns of 15% global surge in AI energy demand over two years
Data centers in the United Kingdom and United States now account for 6% of total national electricity consumption, according to new research from the International Data Center Authority (IDCA). The report highlights a 15% global increase in energy demand driven by artificial intelligence over the last 24 months.
Key details
The IDCA findings reveal that the rapid expansion of AI infrastructure is placing unprecedented strain on national power grids. In the United Kingdom, data center electricity usage has more than doubled from 2.5% in early 2025 to 5.9% today. In the United States, the figure has reached 6%, with some regions experiencing even higher concentrations of demand.
Global investment in data center infrastructure is now approaching $1 trillion annually, representing nearly 1% of global GDP. This massive capital influx is reflected in the growing gridlock for power access; the queue for national grid connections in the UK grew by 460% in the first half of 2025 alone, with some developers reporting wait times of several years.
Why this matters
This threshold marks a critical tipping point for AI's resource footprint. The IDCA research indicates that "significant community and political pushback" typically begins once data center energy consumption reaches the 5% level. The current 6% figure suggests that the AI boom is no longer just a technical or economic trend, but a major factor in national energy security and public policy.
Context
The surge in energy use corresponds with the shift from traditional cloud computing to power-intensive AI training and inference. While the UK government previously estimated that data center usage would quadruple by 2030, the current rate of growth suggests those projections may have been conservative. The strain is already manifesting in local opposition and increased scrutiny of carbon emission reporting by major tech firms.
What happens next
The IDCA is calling for greater transparency from technology companies regarding their long-term infrastructure plans to mitigate community frustration and grid instability. As energy shortages persist in major hubs, regulators are expected to move toward stricter permits for new facilities and potential mandates for on-site renewable energy generation to offset the burden on the public grid.
