Wind energy
Generating energy from wind power is an important and growing part of our energy business. We are working to advance the international development of onshore wind generating facilities and are investing in wind farms, most notably in France, Poland, Romania and Turkey.

Biogas
We use municipal organic waste, energy crops and animal manure to produce biogas, which is used to generate electricity and heat.

Geothermal energy
Geothermal energy is a source with enormous potential. In Germany, we are one of the market leaders in the construction of district heating supply systems on a geothermal basis.

Mine gas
We have been extracting and using the mine gas which arises in coal mines for decades now. In Germany, we have become the market leader in energy generation from mine gas.

Photovoltaics
Photovoltaics are perfectly suited for the sustainable production of green electricity. For many years, we have been designing, building and supporting photovoltaic systems of all sizes - from the PV free-field system to rooftop systems for industrial customers.
