Dresden's new solar heat: Green progress for a CO2-free future!

Dresden-Räcknitz, Deutschland - A new, refreshing wind blows in Dresden-Räcknitz. On June 18, 2025, environmental mayor Eva Jähnigen and Dr. Axel Cunow, CEO of Saxony Energy, inaugurated an innovative open space solar thermal system, which now enriches the city's district heating network. With 140 state-of-the-art modules on an area of 4,000 square meters, which are installed on the site of a former drinking water high tank, the system will produce 700 megawatt hours of hot water every year. This means an important step towards greenhouse gas -neutral energy supply for the city, because the water produced is initiated directly into the district heating network, where it is available for the supply of citizens: inside. [Wochenkurier] (https://www.wochenkurier.info/dresden/dresdner-fernwaerme-waerme-stueck-stueck-co2-free) reports that the solar thermal system has a power of 1.1 megawattpeak and the hot water with special copper pipes with the help of solar energy to up to 95 degrees Celsius is heated.

But this system not only makes a contribution to energy supply. It also promotes biodiversity on site. The open space system is also used as a beekeeping area and houses a variety of plants and animals, which is absolutely justice to the environmental idea. This once again shows how important it is to effectively combat climate change and at the same time to protect the biological diversity, as is emphasized by the Federal Office for Nature Conservation.

a strategy for the future

The initiative of Saxony energy is part of a comprehensive plan that aims to generate the entire Dresden district heating from renewable energy sources by 2035. The company started planning this solar thermal system in 2020. The total cost of the system amounts to an impressive two million euros, with remarkable 1.15 million euros being funded. According to the Heat Planning Act, operators must obtain at least 30 % by 2030 and even at least 80 % of their annual net heat generation from renewable energies by 2040. Dawo emphasizes that Saxony energy already has additional measures, such as the installation of large-scale heat pumps and electrode heating boilers to achieve these ambitious goals.

In addition, the continuous operation of heat pumps will soon start, which use the waste heat from the high -performance calculators of the Technical University of Dresden. This not only uses energy efficiently, but also saves valuable resources. The expansion of renewable energies is about the big breakthrough in the Saxon state capital.

Sustainability and an environmentally friendly energy supply are not only keywords, but urgent necessities in times of climate change. The conversion of the energy supply system to renewable energies is a central challenge that is now actively addressed in Dresden. The climate and nature conservation obliges us to bring the expansion of renewable energies into line with the protection of nature. It is gratifying to see that this system provides an example of how environmental protection and energy generation can go hand in hand.
