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 energy is created at the center of the Earth, around 4,000 miles below the surface, through hot spots in plate boundaries. These hot spots contain more energy than all the gas and oil resources in the world an... More » Science Physics

Geothermal power is a form of renewable energy generated from heat that naturally occurs within the Earth. Radioactive materials, such as uranium and potassium, decay and produce heat deep underground, which is reachable... 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
