Bio-mass plays the main role in heat production from renewable energies
Only about 2% of the heat consumption in 2015 was produced by renewable energies within the region. This corresponds to 735 GWh/a. Of this amount, about 59% (≈431 GWh/a) was produced from bio-mass and bio-gas (including wood and residuals for private households, such as pellets). Heat pumps and flat geothermal plants (up to 150 m deep, for instance with ground heat collectors, geothermal energy probes, or groundwater wells) produced about 20% (≈146 GWh/a) of the local renewable heat. Solar thermal energy produced around 8% (≈60 GWh/a). Sewage- and landfill gas generated nearly 13% (≈92 GWh/a) of the local renewable heat.
Bio-mass and bio-gas thus play the most important role for electricity- and heat production from renewable energies within the region.
