A Critical Look at Geothermal, Solar, and Wind Power Generations

Abstract

Geothermal, solar and wind are all clean, renewable energies with a huge amount of resources and a great potential of electricity generation. The unfortunate fact is that the total capacity installed of geothermal electricity is left behind solar and wind. In this paper, attempt has been made to find the essential reasons to cause the above problem and to look for the solutions. Cost, payback time, size of power generation, construction time, resource capacity, characteristics of resource, and other factors were used to compare geothermal, solar, and wind power generation systems. Furthermore, historical data from geothermal, solar, and wind industries were collected and analyzed. Suggestions have been proposed for geothermal industry to catch up solar and wind industries.
