New research indicates datacentres now consume approximately 6% of electricity in both the UK and the US, with global energy usage from these facilities rising 15% over the past two years. The rapid expansion, fueled by artificial intelligence workloads, is pushing annual global investment in datacentre infrastructure toward $1 trillion, while raising concerns about community backlash over energy strain.

According to a report from an industry body, datacentres—vast warehouses packed with microchips that power AI and internet services—are increasingly straining electricity grids in major economies. The research shows that in the UK and the US, these facilities now account for roughly 6% of total electricity consumption, a figure that has climbed significantly as AI adoption accelerates.
Globally, the proportion of electricity used by datacentres has risen by 15% in the last two years, the study found. This surge is directly linked to the computational demands of artificial intelligence, which requires far more processing power than traditional cloud computing tasks. As a result, annual global investment in datacentre construction and operation is approaching $1 trillion (approximately £740 billion), according to the industry body.
The report warns that this rapid growth could trigger a societal backlash if energy infrastructure fails to keep pace. Communities in both the UK and the US have already expressed concerns about local grid capacity, rising electricity prices, and the environmental impact of powering thousands of high-density server racks. The industry body urged policymakers and energy providers to coordinate more closely to avoid public opposition that could delay new projects.
The findings highlight a critical inflection point for the technology and energy sectors. With AI workloads expanding across industries—from cloud computing to machine learning—the demand for datacentre capacity shows no sign of slowing. However, the research notes that without significant investment in renewable energy and grid modernisation, the sector could face regulatory hurdles and community resistance.

Key Highlights
- Energy footprint: Datacentres now use approximately 6% of electricity in the UK and the US, reflecting their growing role in powering digital infrastructure.
- Global growth: Worldwide electricity consumption by datacentres has increased 15% over the past two years, driven largely by the rise of AI applications.
- Investment wave: Annual global spending on datacentre infrastructure is nearing $1 trillion (£740 billion), underscoring the scale of the industry's expansion.
- AI as a driver: The shift from traditional computing to AI workloads is a primary factor behind the energy surge, as AI models require substantially more computational resources.
- Societal risks: The industry body warns of potential community backlash if energy supply and environmental concerns are not addressed, which could slow future datacentre deployment.
- Sector implications: Technology companies and utility providers may face heightened scrutiny from regulators and local governments regarding energy usage and sustainability commitments.

Expert Insights
The findings underscore a broader structural challenge for the technology and energy sectors. As datacentre electricity consumption rises to 6% in major economies, the pressure on grid infrastructure is intensifying. This trend could influence investment decisions for both hyperscale cloud providers and utility companies, as they assess long-term power availability and pricing.
From a market perspective, the push toward $1 trillion in annual global investment signals that capital is flowing heavily into datacentre construction. However, such rapid growth may bring risks. If energy supply constraints or community opposition delay new projects, the pace of AI adoption could moderate, potentially affecting revenue projections for companies heavily exposed to datacentre leasing and AI services.
Investors may also want to monitor regulatory developments closely. Governments in the UK and the US are increasingly focused on energy security and decarbonisation, which could lead to new standards for datacentre efficiency or mandates for renewable energy procurement. These policies might raise operating costs for some operators while benefiting those with strong sustainability credentials.
While the datacentre sector appears poised for continued expansion, the research suggests that the industry’s ability to manage its energy footprint and maintain social license to operate will be a key factor in determining long-term growth trajectories. Companies that proactively invest in efficient cooling, renewable energy sourcing, and community engagement could be better positioned to navigate potential headwinds.
