German public backs data centre expansion but demands renewable-powered solutions

Executive summary: A majority of Germans support expanding data centres, but they insist on green energy solutions. The demand for sustainable power affects investment decisions and regulatory discussions around data centre electricity use.

Who is involved: German citizens, policymakers, data centre operators, and environmental groups.

Likely next: Negotiations on incentives for renewable-powered data centres and tighter emissions standards are expected in the coming months.

A recent Handelsblatt survey shows that while most Germans support the growth of digital infrastructure, nearly half express concerns over the high electricity consumption of data centres. Respondents call for data centres to be powered by green energy, influencing policy and investment strategies. This tension reflects a broader push to align tech expansion with climate goals.
