ABSTRACT
This chapter examines geothermal power technologies and the issues involved in further utilization of geothermal energy for the production of electric power. It explains the technologies and issues in the utilization of geothermal energy for electric power generation, with a particular focus on the issues facing the development of new capacity, both technical and economic. The chapter presents the technologies and strategies of the geothermal power plant that directly uses geothermal steam in the turbine. The development of new geothermal power plants and the expansion and maintenance of existing geothermal fields depends on the three elements of heat, permeability, and water. Over the long term, the natural resource base for geothermal power could be supplemented with human intervention to create new systems or enhance existing systems. The geothermal water and steam that are produced contain the chemical signatures of the rocks and processes through which they have passed.
