Tecnologia 2

  1. 1. Elena Franganillo Tena y Julián Cuéllar Mangut 2-A
  2. 2. Enegy definitionTypes of energyEnergy sourcesRenewable energyNon renewable energyEnviromental inpactEnergy power stations
  3. 3. The term energy has variousdefinitions, related to the ideaof a capacity to act, transform or put inmotion a object
  4. 4. Hydraulic energySolar enegyWind energyMarine energyGeothermal energyBiomassMunicipal solid waste
  5. 5. Mechanical energy produced by the movement of the water Energy take from the sun using solar panels Energy take from the wind using wind turbines
  6. 6. Can produced three types of energy: Tidal energy;extracted from the tides Wave energy,obtained from the movement of the sea waves Ocean thermal energyproduced from the difference Temperatures between the surface of the sea and the deep seaEnergy come from the heat stored in the earth ´s crust,sometimes appears naturally,for example,geysers and volcaniceruptions.Temperature -150ºC heat can be producedTemperature +150ºC electricity can be produced
  7. 7. Produced from plant remains,forest and agricultural waste,high-energy plantsThis can produced electricity and for trnsformation intocharcoal,biogas,biodiesel,and alcoholThis is produced from dom,estic activitioes in privatespublic buildings,demolition or renovation of houses...The incineration of this wastes can produced electrical orthermal energy
  8. 8. Nuclear energyCoalPetroleumNatural gas
  9. 9. Is stored in the nuclei of atoms and are released in thenuclear.Reaction that occurs in certain atoms.Are two types:Nuclear fusion and Nuclear fissionIt is a sedimentary black rock, very rich in carbon and usedas a fossil fuel.
  10. 10. Formed from the buried remains of plants and animals thatHave decomposed because of bacterial action.Is found in porous rocks under the sea and in otherSedementary bassins,forming oil fields Mixture of gases from decomposed plants and animals. Is found in underground gas fields and in porous rocks
  11. 11. The environmental impact is the effectof a certain action on the environmentin its various aspects. The concept canbe extended, with little use for thepurposes of a natural catastrophe.The main causes of the negativeeffects in the environment arecaused by the humans and sometipes of produce energy.
  12. 12. Mechanical energyThermal energyElectrical energyElectromagnetic energySound energyChemical energyNuclear energy
  13. 13. It is the energy in charge of themovement. There are two different typesof mechanical energy:- kinetic energy is responsable of anybody that move. For example when wemove our hand.- potencial energy: a body is subjected topotencial energy when it is above thesoil. For example a book on a table havepotencial energy.A plane is a good example of both kineticand potencial energy.
  14. 14. This type of energy measuredthe heat or the increase of thetemperature.This type of energy is associated whithan electirc current and if the body isconected to a supply of energy thisbody transform the power into work.
  15. 15. The electromagnetic energy is theenergy that comes from electromagneticradiation. This radiation is composedof waves, such as radio wavesSound energy is the form of energyassociated with the vibration of amatter.
  16. 16. Chemical energy is a chemicalsubstance to undergo a transformationthrough a chemical reaction or, to transformother chemical substancesNuclear energy usually means the partof the energy of an atomic nucleus,which can be released by fusion or fission
  17. 17. Energy power stations are agenerator of energy, a machinethat rotate transformingmechanical power into electricalpower by creating relative motionbetween a magnetic field and aconductor.
  18. 18. Wind turbines haved long produced renewable energy but from now can alsoproduced Eole water said a French engineeringHe explains that the technology works by first generating electricity in thetraditional manner of a wind turbine.The next stage sees air sucked in through the nose of the turbine via adevice known as an "air blower".All air trapped directed through an electric cooling compressor situatedbehind the propellers.This extracts humidity from the air, creating moisture which is condensedand collected.The water gathered is then transferred down a series of stainless steelpipes, and caried to atank in the base of the turbine.Once there, the water is filtered and purified before it is ready for use andconsumption.One turbine can produce up to 1,000 liters of water every day, depending onthe level of humidity, temperature and wind.I think that this is a very good idea because can obtain water from moreplaced not only from the rain
