Datacentres in the UK are now responsible for consuming 6% of the nation's electricity supply, mirroring figures seen in the United States, according to recent research from an industry body. This significant proportion highlights the ever-increasing energy demands of the digital economy, a trend exacerbated by the rapid expansion of Artificial Intelligence (AI) technologies. Globally, the energy consumption of these vast facilities, which power the internet and AI, has surged by 15% over the past two years.
The escalating energy use by datacentres, particularly those supporting AI, is raising concerns within the industry itself. The unnamed industry body has issued a warning about potential societal backlash as communities begin to resist the strain placed on local and national energy grids. This resistance could manifest as opposition to the construction of new datacentre facilities or increased scrutiny of their environmental impact, potentially leading to planning hurdles and increased operational costs for businesses.
For UK households and businesses, this trend carries several implications. A sustained increase in electricity demand from datacentres could put upward pressure on wholesale electricity prices, which would ultimately feed through to consumer bills. The National Grid might face additional challenges in ensuring a stable and reliable supply, potentially requiring further investment in generation and transmission infrastructure. This could mean higher costs for energy providers, which are then passed on to end-users.
The Bank of England closely monitors energy prices as a key component of inflation. Any significant and sustained increase in electricity costs due to datacentre demand could influence the Bank's decisions regarding interest rates. Higher energy prices might contribute to persistent inflation, potentially leading to the Bank maintaining higher interest rates for longer, impacting mortgage holders and the cost of borrowing for businesses. Investors in the FTSE 100, particularly those with holdings in energy companies or technology firms reliant on datacentres, will be watching these developments closely.
While the immediate impact on individual electricity bills may not be drastic, the cumulative effect of increasing industrial energy demand, coupled with efforts to decarbonise the energy grid, presents a complex challenge. Businesses across various sectors, from manufacturing to retail, rely on stable and affordable energy. Any upward pressure on these costs could squeeze profit margins and potentially influence investment decisions and job creation within the UK economy.
UK savers, mortgage holders, and investors should note that persistent inflationary pressures, partly driven by rising energy costs, can erode the value of savings and increase borrowing costs. Investors should consider how energy intensity might affect the long-term viability and profitability of companies they invest in.
