As Artificial Intelligence Accelerates, Global Leaders Are Racing to Balance Digital Growth with Energy Security and Sustainability

Artificial intelligence is transforming economies at an unprecedented pace, but behind every breakthrough lies an often-overlooked reality: data centres require enormous amounts of electricity. As governments and technology companies invest billions in digital infrastructure, the challenge is no longer simply building more data centres. It is ensuring there is enough clean, reliable and affordable energy to power them.

That challenge took centre stage at the 11th Annual Global Conference on Energy Efficiency, hosted by the International Energy Agency (IEA) in Paris, where policymakers, regulators and energy leaders gathered to examine one of the defining issues of the digital age: how to sustain the explosive growth of artificial intelligence without overwhelming the world’s energy systems.

Speaking at the conference, Wolfram Hoffer, Deputy Director-General for Energy at the European Commission, described data centres as strategic infrastructure that will shape Europe’s digital and economic future.

According to Hoffer, the debate is no longer about whether data centres will continue to expand. Their growth is inevitable. The real challenge is ensuring that expansion aligns with broader policy goals around energy security, affordability and decarbonisation.

For the European Union, data centres represent far more than buildings filled with servers. They are becoming critical assets for strengthening digital sovereignty, improving economic competitiveness and accelerating advances in artificial intelligence and digital innovation. Reflecting that ambition, the European Commission plans to nearly triple the EU’s data centre capacity by 2030, enabling Europe to meet its growing digital needs while reducing dependence on external infrastructure.

Yet the benefits extend well beyond the technology sector.

Hoffer explained that AI-powered data centres are becoming indispensable to modern energy systems. They support smarter electricity grids, optimise heating and cooling systems, improve electric vehicle charging, and help utilities manage increasingly complex renewable energy networks. By processing vast amounts of real-time data, these technologies improve efficiency, reduce emissions and lower costs across the energy value chain.

However, this digital transformation comes with significant challenges.

Although data centres currently account for only about 2 to 2.5 percent of the European Union’s electricity consumption, demand is highly concentrated. In countries such as Ireland, where many global technology companies have established operations, data centres already consume approximately 20 percent of national electricity supplies. Major hubs including Frankfurt, Paris, Amsterdam and Dublin are experiencing increasing pressure on electricity networks as more facilities are developed.

The rapid concentration of data centres is creating new concerns around grid congestion, water usage and rising electricity prices. Policymakers are increasingly faced with balancing the need for digital infrastructure against growing pressure on national energy systems.

Rather than slowing investment, European leaders are focusing on smarter planning.

Earlier this year, the European Commission introduced a Strategic Roadmap for Digitalisation and Artificial Intelligence in the Energy Sector, recognising that AI can become a powerful tool for improving energy efficiency while acknowledging the substantial energy demands of digital infrastructure itself.

Transparency has also become a central pillar of the EU’s strategy. In 2024, the Commission established a European Database on Data Centres, requiring operators to report key sustainability and performance indicators. The initiative is designed to provide policymakers with better information, strengthen accountability and ensure that future investments meet increasingly rigorous environmental standards.

Hoffer noted that the pace of technological development demands equally agile regulation. As artificial intelligence evolves, governments must continuously adapt policies that encourage innovation while safeguarding energy security and sustainability.

The discussions in Paris underscored a growing global consensus. Artificial intelligence may define the future of business and society, but its success will ultimately depend on the resilience of the energy systems that power it.
