Renewable energies are those that regenerate naturally or through man’s intervention. Thus, they are able to remain available in the long term because they are generated through non-exhaustible resources. Therefore, they are less aggressive to the environment and even though they require a high initial cost of investment, their use comes cheaper than those of non-renewable sources. Among these energies are wind, geothermal, solar, hydraulic, biomass and hydrogen.
It is generated by the force of wind captured by turbines, which can be transformed into both electrical and mechanical energy. A concentration of wind turbines forms the wind farm, which can be onshore or offshore. The onshore is located on land off the maritime coast or inland and offshore installed at sea.
It is acquired through the heat from the Earth, generated less than 64 kilometers from the terrestrial surface, in a layer of rocks called magma, which can reach up to 6,000 º C. The electric energy can be obtained by drilling the soil in wave places there is large amount of steam and hot water, which should be drained to the terrestrial surface by means of pipelines. Then the steam is transported to a geothermal power plant, which will generate the blades of a turbine. This energy is transformed into electrical through the generator.
It comes from the light and heat emitted by the sun. This source can be used in photovoltaic or thermal form, generating in electrical or thermal energy, respectively. It is one of the most widely used renewable sources. Despite its high cost in investing in the acquisition of solar panels, it has a significant low cost in the long term compared to electricity.
It is the use of the kinetic energy contained in the flow of water currents in rivers, seas or waterfalls. From this, it promotes the rotation of the blades of the turbines that make up the hydroelectric plant system to be transformed into electrical through the system generator.
Clusters all recent derivatives of living organisms that are used as fuels or for the production of these 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 primary production starts to increase the plant biomass of the ecosystem. Part of this accumulated energy is employed by the ecosystem for its own maintenance.
This is produced from industrial processes, among them the use of hydrocarbons. Hydrogen is an odorless, colorless and flammable (normal) gas. It has characteristics that allow it to be a good generator of electric power, besides being able to be used as a type of fuel, through the conversion of hydrogen and oxygen into water. Experts appoint this type of energy as favorable for electric vehicles in the future.
