Facts about power sources
Power sources are divided into permanent natural sources as the sun, wind, water and plants, and non-renewable and consumable sources such as fossil fuels with all its kinds , while the sun is considered to be one of the permanent energy sources due to its possibility of using it in the generation of electric energy by the solar cells, it can also be used in heating the water, and it is not far away to the specialized labs to produces cars that rely on the solar power instead of relying on the non-renewable fossil fuels. The nuclear energy is also one of the energy sources that are produced in the nuclear reactors and by nuclear fission, which could be used in naval propulsion and generating electric power .Moreover there is another source of energy, it is the hydrogen gas, which can be used in moving vehicles that rely on it, as well as in power generation , and this happens through its combination with the oxygen by fuel cells, which do not pollute the environment, producing water as an output . The geothermal energy, such as hot springs and the like source of energy are also power sources where it can be grasped for heating and warming. But the tidal and wind power and energy of dams and waterfalls, are natural mechanical renewable sources and non-consumable, and do not pollute the environment, and it can be used in generating electricity through coal, oil and other fossil fuels which form a major chemical energy that is used as exporters of energy and it is also used in several areas (fuel for cars, for example).
