Resource consumption and grid pressures
Massive data centers required to run artificial intelligence are triggering protests across Europe, testing the continent’s AI ambitions. While many governments and companies have decided to store data within Europe rather than in the United States to increase digital sovereignty, the expansion brings significant resource consumption.
According to the German Ministry for Economic Affairs, cooling data centers requires an average of between 0.4 and 4.4 liters of water for every kilowatt-hour of electricity consumed. High electricity consumption has also raised concerns. Fingrid, Finland’s national grid operator, forecast that electricity consumption would increase by nearly 40% if all projects with signed connection agreements were fully implemented.
In response to these challenges, the European Commission announced a new transparency scheme for data centers regarding energy and water use. Facilities with a capacity exceeding 500 kW will receive an efficiency grade factoring in contributions to the grid, such as waste heat reuse. Teresa Ribera, the Executive Vice-President of the European Commission for a Clean, Just and Competitive Transition, stated that tripling data center capacity cannot mean tripling pressure on grids, water, and energy bills.
Shifts toward rural areas and public backlash
Europe’s most powerful data centers have traditionally been built near major cities such as Frankfurt, London, Amsterdam, Paris, and Dublin due to connectivity and established ecosystems. However, CBRE investment group reports that constraints in power and grid infrastructure are pushing new data centers into cities like Groningen, Barcelona, Brussels, and various rural areas.
As development expands, protests have grown. Hundreds demonstrated in Linz, Austria, against Google’s plans for a data center in Kronstorf. In Ireland, author Sally Rooney led a campaign that overturned planning permission for a data center in Killala, citing national climate policy concerns. In central France, several elected officials in Etrechet resigned over a proposed Google data center requiring up to 1.1 gigawatts of electricity. Mayor Florence Laurent told Le Monde she resigned due to a sense of powerlessness, as the village lacked decision-making power over the project.
Operator perspectives and efficiency measures
Operators counter that data centers can be designed to save energy and serve local communities. A facility under construction in Marseille will use a cooling system consuming no water and 30% less power, while some Scandinavian centers route server waste heat into district heating networks. Furthermore, operators suggest facilities can support local grids by connecting backup power batteries during peak demand or outages, strengthening energy independence alongside digital sovereignty.
