The Electricity

Then, hopeful solutions for the use of the renewable energies without having comment to harm our nature. The phantom of the solar radiation Is certain that the standard firing datas we found them in very many sources of it consults but the radiation emitted by the Sun is worth the pain always to consider that does not have the same intensity to any wavelength, nor the same energy in its different positions and stations from the year. It is important to know the places with a minimum irradiance to assure the work the systems pick up photons that finally would become electrical current until our homes or centers of intention of pick up. Interaction with the atmosphere, global, direct and diffuse radiation the present concept also is basic to maintain latent. The solar radiation, in its passage towards the terrestrial surface, partially is absorbed, reflected and dispersed by the different components from the atmosphere. For the practical effects that they interest to us, these phenomena of absorption, reflection and diffusion, give rise to two components: The direct radiation and the diffuse radiation; first she is the one that comes directly from the solar disc, that one able one to project shades, and second she is the one that arrive dispersed in all directions of the celestial vault. The sum of these two is called global or hemispherical radiation.

How is obtained the electricity? We remember very briefly next: Hydroelectric power station. – That the potential energy of the water stored in a water dam is transformed into the kinetic energy necessary to move the rotor of a generator, and later to transform itself into electrical energy. By that reason, &quot is also called; Hidroelctrica&quot power station;. Thermal power plant. – Where the mechanical energy that is needed to move the generator rotor and therefore to obtain the electrical energy, obtains from the steam formed when boiling the water in boilers.
