“The Department of Science, Innovation and Technology (DSIT) thinks AI datacentres will consume 6GW of electricity by 2030.”
CORROBORATED
The web search results indicate that DSIT projected significant electricity consumption for AI datacentres, specifically mentioning the 6GW figure in the context of government departments disagreeing on energy demands. This is supported by the context provided in the search results.

“In response, DESNZ referred researchers to its broader forecasts for the energy use of Britain’s “commercial services” sector, and said it did not hold separate projections for datacentre growth.”
CORROBORATED
The web search results contain a snippet confirming that DESNZ referred researchers to broader forecasts for the 'commercial services' sector and stated it lacked separate datacentre growth projections, corroborating the claim's core points.

“The forecasts appear to project that the energy use of the entire sector will grow by 528MW between 2025 and 2030 – equivalent to adding the consumption of 1.7m homes by the end of the decade.”
SINGLE SOURCE
The web search results contain the specific figures (528MW growth, 1.7m homes) attributed to DESNZ's forecasts regarding the commercial services sector. While multiple sources are cited, they appear to be referencing the same specific data point from the original reporting context, making it difficult to confirm corroboration from independent sources outside the initial reporting thread.

“It adds: “We forecast that the UK will need at least 6GW of AI-capable datacentre capacity by 2030.””
SINGLE SOURCE
The 6GW forecast is directly quoted from the context of the policy paper mentioned in the search results, but no other independent source corroborates this specific figure or its source.
info
“This will come from multiple AI growth zones – hubs across the country where the government is attempting to attract investment into datacentres.”
SINGLE SOURCE
The concept of AI growth zones intended to attract investment is mentioned in the context of the 6GW requirement, but this specific detail is only present in the context of the initial reporting and lacks corroboration.

“Originally, DSIT’s projections for the carbon emissions of additional AI computing capacity were between 0.025m and 0.142m tonnes of carbon equivalent (MtCO₂) – below 0.05% of Britain’s projected emissions.”
