The city wants to be 100 percent renewable energy by 2035.
It will not achieve this goal without deep geothermal energy.
Geretsried - According to Stefan Drexlmeier from the Energiewende Oberland (EWO), Geretsried was one of the first cities to have a climate protection concept drawn up.
It has been in place since 2010 and some of the measures it contains have been implemented.
Even if the city has not yet been able to rely on district heating generated by geothermal energy, this type of energy generation still plays a major role.
Because without it, the city will not achieve its goal of 100 percent renewable energy by 2035.
This became clear from the presentation by Christine Regauer from EWO at the information evening on the planned Eavor geothermal project, which presented figures from 2016 and 2017.
Most of the energy goes into traffic
"Most of the energy, 45 percent, is used for the transport sector," reported the EWO employee.
Almost 40 percent is used for heating, the rest is electricity.
Of around 90,000 megawatt hours of electricity consumed annually in Geretsried, a good 8 percent comes from renewable energy.
With a good 200,000 megawatt hours of heat consumption, this proportion is 2.7 percent.
There we are still “a long way off” from 100 percent.
The further expansion of renewable energies including deep geothermal energy would bring the desired turnaround a long way forward.
This would scratch the coverage of the 2016 demand, said the expert with a view to electricity consumption.
“But that doesn't mean that saving energy isn't important.” The heat consumption could even be exceeded.
A realistic value that, according to Regauer, could be covered by deep geothermal energy is 100,000 megawatt hours per year.
This could save 10 million liters of heating oil annually.
“A fuel oil truck can transport around 14,000 liters when it is full,” said Regauer.
This would mean that 700 fewer trucks per year would drive through the city.
Saving of 40,000 tons of CO2
Deep geothermal energy would also significantly reduce CO2 emissions.
Around 90,000 tons per year are currently emitted in Geretsried through electricity and heat consumption.
“With deep geothermal energy, we can save over 47 percent CO2,” predicted Regauer.
She expects that at least 40,000 tons can be saved annually.
