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.”
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
An example of a high specific heat is water’s specific heat, which requires 4.184 joules of heat to increase the temperature of 1 gram of water 1 degree Celsius. Scientifically, water’s specific heat is written as: 1 calorie/gm °C = 4.186 J/gm °C.Full Answer >
Plants use chlorophyll, a green pigment responsible for the color of most plants, to absorb light and produce usable chemical energy through photosynthesis. Carbohydrate molecules are created from water and carbon dioxide store in order to store the chemical energy. During this process, oxygen is usually released.Full Answer >
After crude oil is extracted from the Earth, it is burned and used to boil water to produce steam, which is then pressurized and used to turn a turbine that is hooked up to a generator to transfer the mechanical energy into electrical energy. Oil is very combustible and gives off a lot of heat. When the oil is burned, exhaust gasses are produced along with the heat, and the gases are piped away from the boiler, filtered and released into the atmosphere.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 >
