Content:
The energy supply of geothermal energy, stored in hot water or rock around the world, is nearly inexhaustible. It is estimated that geothermal energy could meet our current world energy needs for millions of years. With today's technologies, these environmentally friendly and climate-friendly energy sources can be used virtually anywhere. Geothermal energy, the technical term for geothermal energy, is therefore one of the most widely used renewable energy sources in the world.
The lecture will cover the wide range of geothermal energy. After an overview of the place of geothermal energy within renewable energy production, the geophysical and geological basics of the earth's structure, the earth's heat balance, and the causes of regional and local differences in heat flow will be covered. Some geophysical methods of geothermal prospecting are presented. In the last third of the lecture, the theoretical basis of heat transport within the subsurface and the thermo- and fluid dynamics of engineered geothermal systems (heat exchangers, heat pumps, etc.) are discussed. Finally, a number of geothermal projects in practice will be presented and their technical possibilities and problems will be discussed.
