Geothermal power is generated from the high temperatures that can be found in various parts of the earth's crust such as volcanoes, hot springs, and geysers. The water that surrounds and fills the gaps between the rocks in the crust is raised in temperature by these natural processes. This hot water is then pumped to the surface and its steam is captured and used to create electrical power through a turbine system.
There are three common types of geothermal power: dry steam, flash steam, and binary cycle. Dry steam is rare and uses the steam directly from the earth, flash steam pumps the hot water that naturally occurs in the earth to the surface and utilizes its steam, and binary cycle uses a secondary fluid and its vapor to power a generator.
Dry stream geothermal plants use natural steam directly from the Earth. Once the steam pocket is tapped, the steam is channeled directly into a turbine which converts the thermal energy into electrical power. (more types follow)
