The city of Vienna is the largest city in Austria, the fifth largest in the European Union and the second largest German-speaking city. Like many other cities across Europe, Vienna is facing continuous population growth. Furthermore, rising temperatures due to climate change is another challenge that urgently needs to be dealt with.
Compared to other provinces in Austria, Vienna has the lowest energy consumption per capita. Nevertheless, a lot of fossil energy is still used for the city’s energy supply. In the heating sector, natural gas and district heating dominate the market.
