Datacentres are consuming 6% of electricity supply in the UK and US, with global energy use rising 15% in two years as AI demands surge.
The rapid expansion of datacentres powering artificial intelligence and internet services is placing significant strain on energy grids, according to industry research.
Datacentre electricity consumption has jumped 15% worldwide over the past two years, driven primarily by AI workloads. The sector now accounts for 6% of total electricity usage in both the UK and US.
Annual global investment in datacentres is approaching $1 trillion, reflecting the scale of infrastructure buildout required to support AI deployment and cloud computing services.
The energy intensity of datacentres is triggering community resistance. Local populations are raising concerns about the environmental impact and strain on regional power supplies. Some areas are experiencing grid capacity constraints as major tech companies establish or expand facilities.
Industry bodies are flagging the risk of wider societal backlash if energy consumption continues accelerating at current rates. The challenge intensifies as AI model training and inference demand exponentially more computational power than previous computing paradigms.
Datacentre operators are exploring efficiency improvements and renewable energy integration to address concerns. However, experts note that efficiency gains have historically been outpaced by rising demand.
The sustainability question extends beyond electricity consumption. Water usage for cooling systems, land use, and supply chain emissions are additional environmental considerations facing the sector.
Regulators and policymakers are beginning to scrutinize datacentre development. Some jurisdictions are implementing planning restrictions or requiring renewable energy commitments for new facilities.
The datacentre energy issue reflects a broader tension in the AI economy: the substantial computational infrastructure required to deliver services creates environmental costs that communities increasingly question.
Apple has surged $600 billion in market value as investors shift away from artificial intelligence-focused stocks. The rally reflects growing caution about AI spending among chipmakers and cloud-computing firms.
Scotland's incentives for 'green datacentres' fail to account for the carbon footprint of AI workloads, according to analysis by Action to Protect Rural Scotland. The policy definition, created in 2022 before ChatGPT's release, does not address the substantial emissions generated by AI operations.
The European Union is considering sweeping restrictions on young people's social media access, including potential age limits and outright bans. European Commission President Ursula von der Leyen said new legislation could be proposed within months.
Meta is committing an additional $40 billion to its Louisiana data center campus, bringing total expected investment beyond $250 billion as the company expands its AI computing infrastructure.
