Vienna is taking groundbreaking steps towards a sustainable future with its ambitious heating initiatives.

The city is developing Austria's largest anergy network, using 500 geothermal probes to store summer heat underground for winter use.

This innovative system is part of a larger urban development project that includes 2,000 new apartments and extensive office spaces.

By 2040, Vienna aims to achieve climate neutrality, with two-thirds of its residents relying on eco-friendly district heating.

The city is leveraging advanced technologies like large-scale heat pumps, deep geothermal energy, and industrial waste heat to replace fossil fuels.

A pilot project for underground heat storage is also underway, ensuring surplus summer heat can be utilized in colder months.

These efforts highlight Vienna's leadership in decarbonizing urban heating, setting a model for cities worldwide.
