Geothermal energy is considered one of the most reliable and relatively least expensive sources of renewable energy. The energy and exergy analysis of the power plant, energy process, and single/double and dry steam plant including ORC expansion is investigated to optimize the use of this energy. Exergy analysis has become one of the most important tools for the design and analysis of thermal systems that apply the conservation of mass and energy together with the second law of thermodynamics for the analysis, design, and improvement of energy systems. Therefore, other things that can be explored related to this topic are:

·        Energy and exergy analysis of geothermal power plant

·        Power plants optimization such as in the field of thermodynamics, turbines, separators, and other components,

·        New innovation design in power plants or its components,

·        Methods to overcome silica scaling,

·        Heat and Energy recovery,

·        Power stability,

·        Heat insulation and

·        ORC application in geothermal power plant systems.
