Residents of Kronstorf, a town of roughly 3,500 people in Upper Austria, are challenging Google over a data centre complex that will cover about 50 hectares — an area comparable to some 70 football pitches. Earlier this month, around 400 demonstrators gathered outside the regional government headquarters in Linz to demand answers about the project, which broke ground in April and is scheduled to begin operating in 2027.
The facility is Google's first in Austria. The company says it will meet rising demand for cloud and artificial intelligence services, generate about 100 direct jobs alongside thousands of indirect ones, reinforce the country's digital infrastructure and support local sustainability schemes. At the groundbreaking ceremony, Upper Austria's governor, Thomas Stelzer, described the investment as a strong signal for Upper Austria as a business and innovation location.
Unanswered questions on cooling and the River Enns
Opponents argue that the consultation process has been rushed and opaque. Christina Gruber, a freelance artist and aquatic ecologist who helped organise the protest, said the region needed to reconsider its approach to endless growth and expansion. Andrea Kollmann, a 53-year-old lawyer who travelled from Vienna to join the demonstration, said the plans had advanced far too quickly and that residents had been left in the dark.
At the centre of the dispute are the cooling systems. Data centres house thousands of servers running continuously, consuming large volumes of electricity and producing heat that must be dissipated — often with water. According to media reports, the first phase in Kronstorf alone could draw up to 1.31 terawatt-hours of electricity a year, roughly equivalent to the annual consumption of 375,000 households. Campaigners want clarity on how much water the site will take and what that means for the River Enns, which flows through the region.
Google maintains that its data centres rank among the most energy-efficient in the world. Critics counter that even highly efficient facilities can place substantial demands on power grids and local water sources.
A continent-wide backlash
The Kronstorf dispute is part of a broader pattern across Europe, where hundreds of data centres already operate but overall capacity still trails far behind the United States. As governments and companies race to expand AI and cloud infrastructure, proposals are increasingly meeting local resistance.
In September, Scotland paused approvals for hyperscale AI data centres pending environmental scrutiny. Residents of Spain's Aragon region have taken legal action against a large Amazon buildout, while Amsterdam has imposed a moratorium on new construction, citing space and power constraints. Denmark has relegated data centres to the bottom of its priority list for grid connections, warning of pressure on its electricity network. Regulators in Brussels have also moved on the issue, with the EU preparing sustainability labels for data centres while postponing binding limits until 2027.
Francesca Musiani, an internet specialist at the French National Centre for Scientific Research, said the protests expose a tension between rapid AI expansion and climate objectives, and raise wider questions about digital governance in Europe. For her, the debate is about what sovereignty should mean in practice: the ability of different levels of society to help shape the infrastructures on which they depend.
For Kronstorf, the immediate question is whether Google and Upper Austrian authorities will release detailed environmental data and open a genuine dialogue with residents before construction advances further. The outcome may set a precedent for how other European communities respond when global technology firms come calling.
