  Renewable energyBiomass EnergyBiomass is defined as the set of renewable organic material of plant srcin, animal or from natural or artificial transformation .Then Biomass energy is all this energy that canbe obtained from it, through its direct burning or processing for other types of fuel such as biogas or liquid biofuels.There are different types or sources of biomass which can be used for energy -natural: is found in nature without any human intervention-residual: ncluded in this group are solid products unused agricultural and livestoc! activities, the processes de forestry agribusiness and wood processing.-energy crops: are crops grown in order to produce biomass converted into biofuel The use of biomass in energy applications are mainly producing gas, heat energy (heat) and electricity.  #pplications in $hile %nconventional Energy from Biomass # significant contribution to the use of non-conventional renewable energies constitutesthe e&traction of biogas from landfills. Then it is processed and used, commercially, as city gas component in 'antiago and (alparaiso. #nother interesting application of biomass energy is in the generation of electricity in isolated rural locations.)ind Energy)ind energy is a renewable energy source, to the transformation of the !inetic energy contained in wind into usable energy. )ind is produced by temperature differences between different air masses in the atmosphere, which is heated by the sun. for that, the wind is considered as an indirect form of solar energy.Technologies have been developed for the use of this resource as an energy source, *ero emissions produced during operation and mainly consist turbines that transform !inetic energy of wind into mechanical energy. This is converted to electrical energy by a generator  #dvantages of wind energy)ind is considered as renewable energy. t produces no harmful emissions to theatmosphere, so it does not contribute to the greenhouse effect and climate change.)ind energy is compatible with other land uses, such as agriculture and livestoc!. The facilities are easily reversible.disadvantagesThe impact generated by the installation and operation of wind turbines and a greater level wind farms, are related to the emission of noise and visual impact possible. n environmental impact studies must also ta!e into consideration the potential impact on birds.+roects in operation in $hile   'istema Elctrico de #ysn. a central e/lica 0#lto Baguales1'istema nterconectado $entral 2'$3, ubicado en la localidad de $anela, en la Regi/n de $oquimbo  4eothermal energy   4eothermal energy corresponds to the heat energy contained in the interior of the earth, which is transmitted by thermal conduction to the surface, which is a partially renewable resource and high availability. The set of techniques used for e&ploration, evaluation and e&ploitation of the internal energy of the earth is called geothermal energy. There are two basic types of thermal areas: hydrothermal containing water at high pressure and temperature stored under the earth5s crust at a permeable roc! near a heat source, and hot roc! systems, formed by layers of impermeable roc! overlie an heat source. To ta!e the latter is perforated to achieve, cold water is inected and it is used once heated.The essential elements that determine the formation of geothermal energy are:E&istence of a heat source not very deep and close to the reservoir. This heat source can be produced by volcanic activity or by the interaction between two tectonic plates.+resence of permeable formations containing the reservoir.+resence of geological structures on the site, which acts as a layer 6 in seal, waterproof, heat favoring conservation and reservoir pressure.E&istence of a water catchment area of the reservoir, which determines the characteristic renewable geothermal resource.The medicinal uses and tourism is the oldest form of harnessing this energy. #lso, depending on its enthalpy, has applications in: home heating, agricultural, farming, industrial and power generation.This type of energy is not produced in $hile but for being located on the 7+acific Ring of 8ire7, an area of high geological activity has a potential to generate .
