Geothermal energy from lower temperature (low enthalpy) sources is an increasingly important source of renewable, sustainable energy. Welcome to an interview with Carlo Dietl, who works with both low and high enthalpy geothermal energy sources, and who discusses some of the recent breakthroughs in technology used in geothermal energy.
Why are people and governments pursuing geothermal energy in Europe?
In fact, geothermal energy could be pursued much more. This is in particular true for deep geothermal projects (deeper than 400 m). What is a pity: geothermal energy is the only base load capable regenerative energy source! Main reason for the reluctance is the above mentioned “fracking fear” which for example even led to a general fracking ban in Germany. Moreover, and funny enough, geothermal energy is competing with other regenerative energies. Many politicians and managers of municipal utilities only promote one regenerative energy source instead of looking for a combination of several options.
