This year's club excursion took the Solarfreunde Moosburg club to Haag / Upper Bavaria.
There were three visits on the topic of climate protection.
Moosburg
- First, Lenz Wieser gave a tour of the Vorderleiten am Inn hydropower plant.
The inflow takes place through a kilometer-long tunnel from the Soyener See.
The three turbines from 1923 made the eyes of technology enthusiasts light up: Where can you still find machines today that function so reliably and efficiently even after 100 years?
While the electricity generated in the founding year was still too much, today it only accounts for one percent of the regional energy required.
The members of the association learned that requirements for water drainage, environmental protection and operational safety make climate-neutral power generation almost unprofitable today.

After an extensive lunch break at Hofcafé Bachmeier, the participants visited the renowned Hague engineer and local politician Hans Urban.
The days of fossil fuels have been over on his own properties since 2020.
The newly built private micro-heating network supplies several existing and planned residential and commercial buildings belonging to Urban and his family.

He explained to the participants how the decision was made in favor of a local heating supply with wood chip heating and guided them through his operation.
The project could become the blueprint for the large local heating solution currently being discussed for Haag.
The insiders knew very well that Urban has outstanding specialist knowledge and drive.
However, he feels that his role as a lone warrior is a deficit: “Unfortunately we have no solar friends in Haag,” he regretted.
The sociable part of the excursion was not neglected either.
Some participants visited the Gars am Inn monastery or explored the market town of Haag with the castle garden and monastery in order to fortify themselves in the beer garden of the wheat beer brewery before returning home.
Closed nutrient cycle
The last item on the program of the excursion was a visit to Erlhof AGRAR in Mehnbach near Lengdorf. In this 100 hectare organic farm, biogas is generated and converted into electricity without any animal husbandry. The fermentation residues are spread completely on their own land and thus ensure a completely closed nutrient cycle. As a result of these innovations, the farm became a demonstration operation for the Office for Food, Agriculture and Forests Ebersberg-Erding.
Plant manager Ruppert Hutterer was able to answer numerous questions about organic farming, EU funding and the marketing of energy.
He is currently working with colleagues in agriculture to set up a local heating network for Lengdorf.
During a tour of the courtyard, visitors were also able to get an impression of the enormous amount of work in agriculture, the odor and noise emissions, the scarce economic efficiency and the dependence on the weather.
A significant part of this year's harvest fell victim to the storms of the past few weeks.
