Tecno electric power plants

  1. 1. ELECTRIC POWER PLANTSJose BarqueroJara CadenasCourse:2011/2012Group:3ºA
  2. 2. INDEXElectricity(Electric power plants,transport...)Conventional electric power plants- Nuclear,Fossil fuel thermal,hydroelectric...Non-conventional electric power plants-Wind power plants,solar,geothermal...Environmental impact
  3. 3. ELECTRICITYElectricity is the most widely used form of energy in industrialised societies for two reasons:-It can be easily transformed into other forms of energy(light,heat...)-It can be transported long distances inexpensively and with very little energy lost

  9. 9. NON CONVENTIONAL ELECTRIC P.PLANTS- Wind power plants and wind farms-Solar power plants-Geothermal power plants-Biomass thermal power plants-Ocean power plants
  10. 10. WIND POWERThey use the kinetic energy of the wind to move the PLANTS blades of the wind turbineThere are also “Wind farms” wich are a clean form of generating electricity
  11. 11. Th e r e a r e tw o typ e s : SOLAR POWER PLANTSPhoto-thermal power plants,it Photovoltaic power uses the heat generated by plants,uses solar radiation to produce photovoltaic cells to steam and move a rotor in transform solar the generator radiation into electricity.To do this special mirrors are used,called heliostats
  12. 12. GEOTHERMALThese plants use the heat found POWER PLANTS at deep levels in the earth. This heat may reach the surface in the form of steam, gases or hot waterThis energy may be used directly or indirectly.
  13. 13. BIOMASS THERMAL POWER PLANTSBiomass is subjected to different physical and chemical processes in order to produce fuel such as charcoal,alcohol or biogasThis type of fuel is burnt at biomass power plants.They come from:Forestry and agricultural wasteSpecific crops,such as sunflowers and sugar beetWaste from agri-food industries
  14. 14. OCEAN POWER PLANTSThese power plants use the energy from the seas and the oceans. 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 gradientThese power plants are still in the experimental phase and their level of production is still very low.
  15. 15. ENVIRONMENTAL IMPACTE n v ir o n m e n t a l im p a c t a s s e s m e n tAn electrical power plant produces an ecolological change because it produces waste and needs an infrastructure.To avoid that is necessary to do an environmental impact assesment and an environmental study to show all the consequences

  17. 17. Do you think wind turbine can produce fresh water?We think that 1000 liters of water are a very small amount of water to everyody, but it is a good idea that we can develop with better technologyWe think that in a near future this idea can be developed with better results
