How do renewable energy arise?

Renewable energies are naturally regenerated or through the intervention of man. Therefore, they are able to maintain available in the long term because they are generated through non-exhausting resources. Therefore, they are less aggressive to the environment and although they require a high initial cost of investment, its use comes out cheaper than those of origin non-renewable. Among these energies are wind, geothermal, solar, hydraulics, biomass and hydrogen.

Wind

It is generated through the force of the wind captured by wind turbines, which can be transformed into both electricity and electricity Mechanical. A concentration of wind turbines forms the wind farm, and can be onshore or offshore. The onshore is located on land off the coast maritime or inland and offshore installed at sea.

Geothermal

It is acquired through heat from Earth, generated at less than 64 kilometers from the earth’s surface, on a layer of rocks called magma, which can reach up to 6,000ºC. Electricity can be obtained through soil drilling in wave sites there is lots of steam and hot water, which should be drained to the earth’s surface by means of Pipes. Then the steam is transported to an electric power plant which will generate the blades of a turbine. This energy is transformed through the generator.

Solar

It comes from the light and heat emitted by the sun. This source can be used in a photovoltaic or thermal way, generating in energy electrical or thermal, respectively. It is one of the most renewable sources Used. Despite its high cost of investing in the acquisition of boards has a significant long-term low cost compared to energy Electric.

Hydraulic

It is the use of kinetic energy contained in the flow of streams of water in rivers, seas or waterfalls. From this, it promotes rotation of the turbine blades that make up the hydroelectric plant system to be transformed into electrical through the system generator.

Biomass

Agglomerates all recent derivatives of living organisms that are used as fuels or for the production of such fuels. It is used in the production of energy from processes such as the combustion of organic material produced and accumulated in an ecosystem, but not all of the primary production begins to increase the plant biomass of the ecosystem. Part this accumulated energy is employed by the ecosystem for its own Maintenance.

Hydrogen

This is produced from industrial processes, including them the use of hydrocarbons. Hydrogen is a gas (in normal state) odorless, colourless and flammable. It has characteristics that allow it to be a good electric power generator, besides being able to be used as a type of through the conversion of hydrogen and oxygen into water. Experts point to this type of energy as favorable for vehicles in the future.
