    • ELECTRIC POWER PLANTS Adrián Mendoza Zárate Ramón Barrabés Parra 3ºA
    • IndexConventional Power Plants -Nuclear Power Plants -Fossil Fuel Power Plants -Hydroelectric Power PlantsNon-conventional Power Plants -Wind Power Plants and Wind Farms -Solar Power Plants Photo-Thermal Power Plants Photovoltaic Power Plant -Geothermal Power Plant -Biomass Thermal Power Plants -Ocean Power Plant
    • CONVENTIONAL POWER PLANTS: NUCLEAR POWER PLANTSA nuclear plant is an industrial facility used for generating electricity from nuclear energy. Characterized by the use of nuclear fuel such as uranium which provides heat by nuclear reaction which in turn is used through a thermodynamic cycle to produce movement of alternators which transform the mechanical work into electric energy. These plants consist of one or more reactors.
    • ADVANTAGES AND DISADVANTAGESAdvantages:-low CO2 emissions Disadvantages: -Risk of radiactive emissions -Danger of nuclear disaster -Radiactive waste
    • FOSSIL FUELS POWER PLANTA fossil-fuel power station is a type of power station that burns fossil fuels such as coal, natural gas or petroleum to produce electricity.A this type of power plants, water is heated in a boiler by the heat generated from the combustion of a fossil fuels.
    • ADVANTAGES AND DISADVANTAGESADVANTAGES:-Great capacity and high performances DISADVANTAGES: -Respiratory diseases -Increases the greenhouse effect
    • HYDROELECTRIC POWER PLANTSThis type of power plant uses the potential energy provided by the height of the stored water in a dam, converting it into kinetic energy.This energy moves the blades of the turbine
    • ADVANTAGES AND DISADVANTAGESAdvantages:-They dont require fuel, they use a renewable form of energy 12 Disadvantages: 10 8 -Risk of disaster if a dam 6 4 breaks 2 -Risk of the disappearance of 0 flora and fauna
    • NON-CONVETIONAL POWERPLANTS: WIND POWER PLANTS & WIND FARMSThese power plants use the kinetic energy of the wind to move the blades of a rotor at the top of a tower; this is referred to as the wind turbine.Winds farms are clean form of generating electricity. However, they can only be installed in places with appropriate wind conditions.
    • ADVANTAGES AND DISADVANTAGESAdvantages:-Clean-Possible domestic production Disadvantages: -Discontinous and randoom -Low levels of performances
    • SOLAR POWER PLANTSPhoto-thermal power Photovoltaic power plants: plants:The heat generated by Solar radiation is solar radiation produces transformed directly steam that is used to into electricity by move the rotors in the panels of photovoltaic generator. cells.
    • ADVANTAGES ANDDISADVANTAGES OF THERMAL POWER PLANTSAdvantages:-Dont pollute-Low maintenance Disadvantages: -High installation costs -The Sun does not shine on all sides of the earth
    • ADVANTAGES AND DISADVANTAGES OFPHOTOVOLTAIC POWER PLANTSAdvantages:-Domestic production Disadvantages: -They pollute in the contruction -It has a strong visual impact
    • GEOTHERMAL POWER PLANTUse the heat found at deep levels in the earth. This heat may reach the surface in the form of steam, gases or hot water.Geothermal energy may be used directly; for hot water and heating, and indirectly; the heat generates steam, which produces electricity.
    • ADVANTAGES AND DISADVANTAGESAdvantages:-Job creation and economic benefits Disadvantages: -May release harmful gases
    • BIOMASS THERMAL POWER PLANTSConsists of all organic compounds that are produced through natural processes. They may come from the following sources:-Forestry and agricultural waste-Specific crops, such as sunflowers-Waste from agri-food industriesThis type of fuel is burnt at biomass power plants
    • ADVANTAGES AND DISADVANTAGESAdvantages:-Reuses forestry and household waste Disadvantages: -Excessive exploitation of natural resources -Increases the greenhouse effects
    • OCEAN POWER PLANTSThese power plants use the energy from the seas and the oceans. The concept is to use three types of energy from the sea:-The mechanical energy from the tides-The mechanical energy from the waves-The energy from the oceans thermal gradient
    • ADVANTAGES AND DISADVANTAGESAdvantages:-Clean and quiet Advantages: -It leads to the displacement of wild life habitats
