Natural Resources are a Source of Energy

NATURAL RESOURCES mean you want all the resources that the Earth gives us. Our planet has many sources from which we get energy, the most important are: water and wind, used since ancient times, and then began to use the heat from the sun and biomass. From these resources are obtained various types of energy: HYDROELECTRIC ENERGY, using only water. Water is one of the first sources of energy used by man: building mills on the rivers, and exploiting the motion of water that just by moving the blades of the windmills produce energy, or with the construction of dams, that barring a course of artificially 'water, created invaded, and the large amount of water is used for energy production. The energy produced will not cause any damages to the environment and can be reused. WIND POWER, which uses the force of the wind. The wind was one of the first sources of energy used by humans, using the movement of the blades of the windmill. The energy produced is also clean and reusable. SOLAR ENERGY, which uses the energy emitted from the Sun, in the form of heat, to heat the buildings of a city, or may be photovoltaic, that is using energy emitted from the sun to generate electricity. Even solar energy is clean and reusable. Biomass energy, which uses the energy produced by combustion of substances of animal or vegetable origin. The disadvantage is that the substances of animal or vegetable origin are in limited in nature. These types of energy are "clean", instead not harm the environment, and are reusable. But the man prefers to use other types of energy, such as atomic energy, which pollutes the environment and much could be very dangerous. These types of energy are used because of their use can be seen a lot of energy. One of the remedies being proposed, is to abandon them and to use clean energy. The problem is that this kind of energy is not enough to satisfy the needs of a Country.
