Low Carbon Emissions: Geothermal power plants produce very low levels of carbon dioxide and other greenhouse gas emissions compared to fossil fuel-based power plants. As the world focuses on reducing carbon emissions to combat climate change, geothermal energy becomes an attractive option to meet energy needs without contributing significantly to global warming.

Growing Demand for Binary Cycle Power Plant: In binary cycle power plants, the geothermal water or steam beneath the Earth's surface is not directly used to drive the turbines. Instead, a heat exchanger is employed, where the geothermal water is pumped and heats a separate liquid called isobutene. Isobutene has a lower boiling point than water, so it transforms into steam when heated.

The North America is the dominant region in the geothermal power market. It has a well-established geothermal industry with a significant number of operational geothermal power plants. The region's dominant position is attributed to its abundant geothermal resources, particularly in countries like the United States and Mexico.
