The correct answer is B. Geothermal energy.
Geothermal energy is derived from heat within the Earth. The heat comes from two main sources: (1) the decay of radioactive elements in the Earth’s crust and (2) primordial heat left over from the formation of the Earth. Geothermal energy can be used to generate electricity, heat homes and businesses, and provide hot water.
Solar energy is derived from the sun. The sun is a giant ball of hot plasma that emits a tremendous amount of energy in the form of light and heat. Solar energy can be used to generate electricity, heat water, and power homes and businesses.
Hydroelectric energy is derived from the movement of water. When water flows downhill, it can be used to turn a turbine, which generates electricity. Hydroelectric power is a renewable energy source that does not produce greenhouse gases.
Nuclear energy is derived from the splitting of atoms. When an atom is split, it releases a large amount of energy. Nuclear energy can be used to generate electricity, but it also produces radioactive waste.
