Wind
Most wind energy comes from turbines that can be as tall as a 20-story building. the biggest wind turbines can generate enough electricity to supply 600 homes. Wind farms have also been established, and they usually have ten or even a hundred of these turbines lined up and ready for use. it is a clean source of renewable energy, producing no air or water pollution. Plus, wind is free!
Those who use solar power are using tech that harnesses the energy of the sun. The most common type of tech would be solar panals, which contain photovoltaic cells. When sunlight comes into contact with these cells, electrons are knocked loose from their atoms. Electrons are then allowed to flow through the cell, which generates electricity. There are also solar thermal power plants. Solar energy is effetive because:
1) the sun is a limitless source of energy
2) it is pollution and noise free
The world should learn to incorporate alternate sources and forms of energy into its way of life. Despite the drawbacks, solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Japan, Germany, and the United States are major markets for solar cells. The wind energy industry is booming; Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China. In the USA, two new Generation III reactors are under construction at Vogtle. U.S. nuclear industry officials expect five new reactors to enter service by 2020, all at existing plants.
Solar
Nuclear energy originates from the splitting of uranium atoms in a process called fission. The nuclear reactor inside the plant uses Uranium rods as fuel, and the heat is generated when the neutrons smash into the nucleus of the uranium atoms, which split roughly in half and release energy in the form of heat. Nuclear power produces around 11% of the world's energy needs, and produces huge amounts of energy from small amounts of fuel, without the pollution that you'd get from burning fossil fuels.
