Geothermal Power Market Outlook - 2026
The global geothermal power market was valued at $4.6 billion in 2018, and is projected to reach $6.8 billion by 2026, growing at a CAGR of 5.0% from 2019 to 2026. Geothermal power is a stable and independent power generation system, which uses warm vitality of the earth's magma to produce power. Geothermal power plants utilize the steam that is produced from hot water found around a mile or more below the earth's surface to rotate turbines that start a generator, which further produces electricity.
In geothermal power plants steam is used to turn large turbines, which run electrical generators. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. At a geothermal power plant location, wells are drilled 1 or 2 miles deep into the Earth to pump steam or hot water to the surface. Geothermal power is considered a clean and environmentally friendly energy source. It produces minimal greenhouse gas emissions, has a small land footprint, and does not require water for cooling like traditional power plants. The environmental benefits of geothermal power, including air pollution reduction and water conservation.
Three types of geothermal power plants are operating presently, which include binary cycle, dry steam, and flash steam. Government organizations are putting in efforts to reduce the dependency on oil for domestic energy use. To do so, several activities are explored and exploited to use renewable energy resources as an alternative energy source. For achieving this goal, the Government of Indonesia formulated a National Energy Policy, which involves guidelines for intensification, conservation, and diversification of energy.
