Geothermal power plants work by harnessing natural heat from Earth's interior to generate energy in the form of electricity. Geothermal energy is a renewable power source. The four types of geothermal power plant are bin... More »

Geothermal power is generated by capturing and utilizing the steam and hot water produced by geothermal springs. As cold water seeps into the Earth’s crust, a layer of hot and molten rock heats it up and causes it to ris... More » Science Physics Thermodynamics

Geothermal power plants produce electricity by using steam from hot underground water to turn turbines and activate a generator. Some types of geothermal power plants use the steam to directly turn the turbine, while oth... More »

The heat produced by geothermal energy is created by the interaction between the molten mantle of the Earth and the Earth's crust. When this heat breaks through the crust it erupts in the form of steam, water geysers or ... More »

Geothermal energy is derived from the heat naturally emitted from the Earth's interior. This form of energy may be harnessed from underground steam and water sources and heat from solid rock and magma. It is a renewable ... More »

Nuclear energy is produced in much the same way that electricity is produced by other power plants; the splitting of atoms creates heat, turning water into steam, and then the pressure of the steam turns the generator wi... More »

Geothermal energy works by using the heat created by the Earth and turning it into an energy source for people to use. This clean, renewable resource provides energy in the United States and around the world. More » Science Earth Science Geology
