What are the different types of natural energy?
natural energy is energy derived from natural sources such as the sun, wind, water and even the earth itself. Many natural energy sources are clean and renewable, but not all of them. One of the most polluting forms of human energy, fossil fuel, is derived from natural sources. In the 21st century, scientists and people around the world strongly focus on the shift of energy consumption from polluting natural energy sources on pure burning, sustainable forms such as solar energy.
Solar energy can be created in two ways. Solar panels absorb sunlight, causing light waves to interact with electrons on the solar panel and create electric current. Solar energy can also be used to heat things; By attaching the solar heat collector to the pipe with the circulation of water, the heat is transferred from the sun to the water. Solar energy is a natural energy that is renewable and clean, which means that it has little or no damage to the environment. It is consideredMany Scientific Experts to be an important part of the change of pure, renewable natural energy.
wind and hydroelectric power plant sources use natural force to create energy. Umístěním větrných turbín nebo větrných mlýnů do trvale vázaných oblastí nutí větrné turbíny, aby se točily a generovaly elektrický proud. Hydroelektrická energie často využívá masivní energii padající vody vytvořením přehradního systému, kde voda spadá z vyššího výšky do spodního a prochází turbíny vytvářejícími energii na cestě. Větrná i hydroelektrická energie jsou velmi čistými zdroji přírodní energie, i když někteří obavy, že ochrana vody může být problémem s vodními zdroji.
natural energy sources such as the sun, wind and water are considered to be modern alternatives to fossil fuels. Since the 19th century, people relied on fossil fuels such as coal, gas and oil to drive their homes, light lamps, trafficMotors and flying aircraft. Unfortunately, fossil fuels are a very slow renewal source and very bad for the environment while burning.
fossil fuels are created by the decay of organic plants and animal substances buried under the rock and soil. The process of creating fossil fuels is extremely slow; Some experts estimate that the distribution of organisms on usable fuel takes about 300 million years. As a result of human use, the Earth occurs very quickly from fossil fuels. In addition, when fossil fuels are released by carbon dioxide, nitrogen oxide and other harmful chemicals into the environment, increases greenhouse gas levels and leads many scientists, believes, to global warming.
natural energy, which is renewable and clean, allows people to meet energy needs without damaging the environment. Since the 1970s, science, government and citizens are increasingly aware that it is necessary to move efforts to research and develop renewable energy systems. I'll switchThus, for renewable and safe natural energies, they hope that it will reverse damage to the environment and in the future in the future instill in the environment.
