1. What is Geothermal energy?
Geothermal energy is the thermal energy in the Earth's crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions.
2. What are the types of Geothermal Energy?
there is dry steam, flash steam, and binary cycle.
3. How is heat from inside the earth tapped as a source of energy for human use?
Geothermal springs for power plants. Currently, the most common way of capturing the energy from geothermal sources is to tap into naturally occurring "hydrothermal convection" systems, where cooler water seeps into Earth's crust, is heated up, and then rises to the surface
4. How can geothermal energy generate electricity?
Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity.
