Geothermal energy power plants use the steam and hot water found underground to generate electricity through turbines. Wells are typically drilled at between 150 to 400 feet deep to access the energy. Currently, the most common geothermal energy production system is called a flash steam power plant. This type of power plant routes hydrothermal fluid from a well at temperatures over 182°C (360°F) under high pressure into a tank at the surface. The tank’s much lower pressure causes some of the fluid to quickly dissipate as vapor, which is then used to drive a turbine. IoT is used in geothermal power plants to increase energy station capacities and to catch problems with the power stations ahead of time.
