The city must increasingly rely on renewable energies, motivate private households to replace old heating systems and renovate all city buildings to make them energetic.
Only in this way can the national climate targets be achieved by 2030.
Germering
- At the end of 2020, the city commissioned the Institute for Systemic Consulting at the Landshut University of Applied Sciences to draw up an energy use plan for the city.
Now the institute director Prof. Petra Denk presented the first results of her investigations.
An inventory of the entire city's energy consumption showed that Germering has an annual requirement of 450 gigawatt hours - 80 percent is used for heating, 20 percent for electricity generation.
The largest consumers are private households with 61 percent, 34 percent come from the economy and five percent from urban properties.
Private households
It then became problematic with the next figures that the physicist provided: “87 percent of the energy is generated with fossil heat, i.e. oil or gas.
That is a relatively high national average. ”The aim must be to increase the share of renewable energies from currently 13 to 19 percent by 2030.
Above all, something has to be done with private households, said Denk.
Because here 47 percent of the heat is still generated with oil heating.
The economy, on the other hand, has already reached 95 percent natural gas.
From the point of view of the expert, something also needs to change when it comes to electricity consumption.
The share of electricity from renewable energies is only five percent here.
The city's carbon footprint doesn't look too bad at first.
According to Denk, each resident uses an average of three tons per year - although traffic is not included in all of these figures.
The national average is 5.9 tons.
In order to meet the climate targets, however, it must be halved by 2030.
One problem for Germering is that the designated new development areas counteract the savings targets.
Solar cadastre
Nevertheless, Petra Denk was rather optimistic.
“There is great potential in the expansion of renewable energies.” A solar cadastre that has been created shows that with photovoltaic systems on roofs there is an additional maximum of 87 gigawatt hours (GW / h).
Even with open space photovoltaics, for example along the railway line, there is a potential of 38 GW / h.
The use of wind power on Germeringer Flur would also be possible but difficult.
By far the greatest amount of unused energy lies in the depths.
Around 98 GW / h can be generated annually with geothermal energy.
The increased use of heat pumps could also make a contribution to the energy transition.
In a short discussion, the city councils welcomed the good data base that had now been obtained.
Daniel Liebetruth (SPD) also said that the numbers make him quite affected, because: "Everything has to change in just nine years."
On the one hand, Sepp Dürr (Greens) spoke of a sad result: “We are not doing well.” On the other hand, the analysis also showed: “We have everything under control and can achieve our goals with two technologies: solar and geothermal energy.” He pleaded for getting started now and not waiting for the final report by Petra Denk promised for January.
Before that, however, the expert warned: “We should start with electrical energy first.” Geothermal energy is a huge project, so you first have to specify the framework conditions.
She would now first push public relations.
