A prime example of man-made nuclear energy is the generation of electricity. A prime example of natural nuclear energy is the nuclear reactions the sun produces to create heat and light. Nuclear energy involves a process called “fusion.”Know More
Fusion involves the collision of atomic nuclei, an event that creates a tremendous amount of heat. In generating electricity, for instance, the heat created by fusion warms water to the boiling point, which releases steam. This steam powers turbines that create electricity.
In the core of the sun, the heat and pressure are extreme enough to create the fusion needed to unleash its natural nuclear energy. Less than 8 percent of the energy needs in the United States are met via nuclear energy, according to the U.S. Department of Energy. Petroleum, natural gas and coal are the primary energy resources in the United States and many other countries around the globe.Learn More
The sun's energy comes from the nuclear fusion reactions that happen within its core. When atoms of hydrogen come together in the core of the sun, they fuse to become another element: helium. This reaction produces energy.Full Answer >
Thermal energy moves from one object to another through heat energy. Heat energy moves through convection, conduction and radiation. The internal movement of atoms generates energy in matter. As the temperature of matter increases, the internal movement also increases.Full Answer >
The primary heat source for the Earth is the radioactive decay of uranium, thorium and potassium, found in the mantle and crust. The Earth produces more heat through phase changes, such as the freezing of liquid iron in the inner core and minerals in other parts of its core. In addition, the slow cooling process of the Earth gives off heat that melts magma.Full Answer >
Tidal energy works by using special generators to convert the energy produced by the rise and fall of ocean tides into electrical power. The force of the water drives turbines placed in tidal streams or installed in dams called barrages.Full Answer >
