Application of Geothermal Energy

People have been using geothermal energy for bathing and washing of clothes since the dawn of civilization in many parts of the world. However, it was first in the twentieth century that geothermal energy was used on a large scale for direct heat extraction for district urban heating, industrial processing, domestic water and space heating, leisure, balneotherapy applications and electricity generation. Prince Piero Ginori Conti initiated electric power generation with geothermal steam at Larderello in 1913. The first large scale municipal district heating service started in Iceland in 1930 [9]. In 2010, geothermal resources have been identified in more than 80 countries and there are quantified records of geothermal utilization in more than 50 countries in world. The result shows that use of geothermal energy for both electrical generation and direct heat extraction is going to accelerate in the near future.
