Datacentres Devouring Demand: A Growing Concern for the UK and US
The hum of datacentres has become an integral background noise in our increasingly digital lives. These vast warehouses power the internet, enable AI, and store the world’s collective online presence. However, a disturbing reality is emerging: datacentres are consuming 6% of electricity in the UK and US, with global investment approaching $1 trillion – nearly 1% of the global economy.
This growth has been fueled by the exponential expansion of tech giants’ infrastructure needs. But it also raises social and environmental concerns. As the world grapples with climate change and energy shortages, datacentres are becoming a hotbed of controversy. The International Data Center Authority (IDCA) warns that rising power usage globally is sparking societal and political concerns.
AI’s insatiable appetite for computing resources is a key factor in this growth. Google’s proposed AI datacentres in the UK have been met with community resistance, with some developers misstating the carbon impact of these projects. The IDCA research highlights that once a nation’s datacentre footprint reaches 5% consumption level of national grids, significant community and political pushback occurs.
The trend is particularly concerning given the UK government’s estimate that datacentres will increase their electricity usage fourfold by 2030. Both the UK and US are already above the global average of 2%, with Singapore and Lithuania topping the list at 19% and 11% respectively. Greenpeace UK has sounded the alarm on an “unchecked AI boom” leading to higher energy bills, water stress, and a renewed reliance on fossil fuels.
Tech companies have been criticized for downplaying or ignoring the environmental impact of their massive datacentre footprints. Microsoft boasts of its 1.2 million sq ft Mount Pleasant facility in Wisconsin, but the actual environmental cost is often overlooked. The IDCA’s figures align with recent estimates that energy use rose 17% in 2025, outpacing global electricity demand growth.
A staggering 13% of datacentre consumption in the US comes from unused “zombie” services – running apps that were never switched off but are unused. This wasted consumption totals over 3GW, highlighting inefficiencies throughout the world as cloud computing rises.
The dark side of digital dreams is not just an environmental concern; it’s also a security threat. Datacentres have become critical infrastructure, and attacks on these facilities in the Middle East have raised concerns about breached physical security. Cybersecurity is now intertwined with physical security in datacentre operators’ unified security strategies.
As we continue to digitize our lives, we must confront the reality of our energy demands. The IDCA’s call for transparency about water and energy usage, proper environmental impact assessments, and a ban on new polluting plants being built to power AI is essential. We cannot afford to be swept along by the enthusiasm of tech billionaires whose profits depend on this expansion.
The future of datacentres will be shaped by our collective willingness to address these concerns. Will we prioritize sustainability, transparency, and accountability, or will we continue down the path of unchecked growth? The choice is ours, but the clock is ticking – along with the energy meters.

The datacentre industry's voracious appetite for energy is a stark reminder that the dark side of innovation often lurks in plain sight. While proponents tout AI as a force for good, its true cost – in terms of power consumption and resource depletion – remains woefully underestimated. As datacentres approach 5% grid penetration, governments and communities will face increasingly vocal pushback. It's high time the industry prioritizes sustainable practices and transparent reporting over profits; only then can we ensure that AI doesn't become a costly, energy-hungry Trojan horse for our planet's future.

The exponential growth of datacentres is a ticking time bomb for our energy infrastructure and environmental sustainability. While tech giants are rightly pushing the boundaries of innovation, they're also recklessly fueling our addiction to energy-hungry AI and cloud computing. It's not just about meeting demand – it's about setting a precedent that undermines efforts to reduce carbon emissions. What's striking is how little attention is being paid to the long-term costs of datacentre expansion, particularly in areas where the social and environmental impacts are most acute.

The real issue here isn't just the staggering electricity consumption of datacentres, but also their water usage and e-waste generation. The article glosses over these pressing concerns in favor of debating AI's carbon footprint, which is only one part of the problem. We need a more holistic approach to addressing the datacentre conundrum: investing in sustainable cooling solutions, implementing waste reduction strategies, and exploring alternative infrastructure configurations that minimize environmental impact. Anything less will only exacerbate the existing issues.
