Energia verde - Mall-BB
Green energy is energy that is obtained without pollution. The main type of green energy is the solar energy. Sun is a sphere of gas with a diameter of about 1.4 million km, with high temperatures (the temperature inside the sun is about 15 million degrees Kelvin). This huge temperature, combined with a high pressure creates ideal conditions for fusion reactions. These reactions occur between the hydrogen atoms combine to form helium atoms. After this process is releasing energy in the form of radiation. The amount of solar energy reaching a point a particular place on Earth's surface is called the solar constant, its value depending on various factors. The maximum value is recorded when the sun is at noon and the sky is clear, the radiation on a horizontal surface is 1000 watts per square meter. The solar constant decreases when the surface is not oriented perpendicular to the sun. Thermo-solar energy Electricity is obtained with solar thermal technology that uses solar radiation to gain steam. This steam powered turbines generating electricity.
Water heating systems use small flat plate collectors to transfer heat energy to water sun. Water heating systems large (solar thermal power plants) produce electricity using a turbine powered by steam produced by boiling a liquid using solar radiation energy. Solar thermal power plants using three types of capture sunlight - central receiver systems, which concentrate sunlight to a central collector - alibi systems, focusing sunlight on tubes filled with liquid - Systems parable focuses sunlight collector mounted to the focal point of small-scale applications generally use flat plate collectors to heat a water tank.
Can be used in applications such as hot water for use cansnic, heated pool, commercial and domestic uses, solar thermal power plants. Advantages of using solar electricity-termico: • get electricity and hot water at the same time • plants can be tailored to specific applications are used little or no pollution • Centraal building solar thermal is much faster than plants coneventionale solar cells: Photovoltaic cells are used to convert sunlight into electricity. Photovoltaic panels today are increasingly widely used, especially in remote areas, where electricity can not be produced by conventional methods. PV systems are easy to use, maintenance is cheap and of short duration and has no risk of pollution to the environment.
