Renewable energy

 They are considered renewable energy those energies that occur naturally continuous. They are essentially characterized by being clean, not to pollute the planet and reduce their resources.

SOLAR ENERGY:Is to capture the energy of the sun's rays reaching the earth's surface and then use it as heat. There are three ways to use essential: low, medium and high temperature. The heat transfer fluid flows through the collector, through channels, and is heated by the sun's rays that affect it. This liquid can be used directly or stored in an accumulator for later use. These applications are typically for the production of electricity from a heat reservoir at high temperature, in the same way you would a conventional power station without the use of fossil fuel.

WIND ENERGY: Is to convert wind power into electricity. The turbines may be of horizontal or vertical axis. The most efficient and the most used are the horizontal axis. The breakthrough that is taking this technology is expanding the range of everyday work. The rotor and the nacelle of the wind turbine tower are placed in one because the wind increases with altitude above the ground. They are located away from obstacles like trees, buildings, etc.

 
SMALL HYDRO:Is to convert the kinetic energy and power of a waterfall into electricity. The water drives a water turbine which in turn transmits it to a mechanical energy generator. The first advantage of the flow of a river, diverting it to the center and passing through a turbine.Normally this water is stored for supply to towns and irrigation areas. The advantage of this technology is that it can generate electricity at the precise moment it is needed, thus adapting the electrical need.


BIOMASS ENERGY:Is to harness the energy value of organic materials by combustion or use of derivatives in the gaseous or liquid.  Each type requires a different approach to technology: a gross biomass should be burned, whereas the liquid biomass and biogas is used as fuel for combustion engines. The forest wood, garden waste, egg shells and nuts, olive pits and other industrial residues companies are different types of solid biofuels.

GEOTHERMAL ENERGY: Is one of the few that is not rooted in the influence of the sun on the earth's crust, but it comes from the large temperature difference between the surface of the earth and its kernel. It consists in the use of the heat flux leaving the core of the earth to the surface.The facility is best known for producing heat for buildings. Spas and heated swimming pools, heating and hot water, agriculture, aquaculture and industrial uses.
