Geothermal energy is a promising energy source. Not only due to its large and 
area-wide potential but also because of its base load ability geothermal plants 
can contribute to energy supply. 

However, a contribution to a sustainable heat and electricity provision is only 
reasonable if its use – compared to given alternatives - results in general 
benefits for the environment. This is true for the environmental impacts 
connected with the whole life cycle, i. e. life cycle assessment regarding 
construction, operation and deconstruction as well as the therewith combined 
process chains, but also for the effects on the natural environment, which are 
primarily site specific and regional.

On this background a survey of local environmental impacts by using 
geothermal high and low enthalpy fields will be given and a case study of a life 
cycle assessment presented.
