  1. 1. EnergyAlejandro MorenoManuela Benítez2ºA
  2. 2. IndexEnergy definitionTypes of energyEnergy sourcesRenewable and non renewable energyEnviromental impactEnergy power stations
  3. 3. Types of energyMechanical energyElectrical energyElectromagnetic energySound energyChemical energyNuclear energyThermal or calorific energy
  4. 4. Mechanical energyMechanical energy is energy that is produced bythe position and motion of a body, can bepotential and kinetic.-Kinetic energy is produceed by the motion of anobject-Potencial energy is produced when an objectmove from its stable position of equilibrium.
  5. 5. Electrical energyThe electrical energy produced by the motion of electrical charges through a lead wire.
  6. 6. Electromagnetic energy Is the energy that is produced from electromagnetic radiation.This energy istransported by electromagnetic waves. One of this is the luminous energy.
  7. 7. Sound energyThe sound energy is the energy that carry sound waves. It comes from the vibrational energy ofsound focus and spreads to the medium particles that cross in the form of kinetic energy and potential energy.
  8. 8. aChemical energy is a form of potentialenergy. Is the energy involved in thebond formed between two atoms. Eachatom in a chemical compound involvesdifferent amounts of energy.
  9. 9. Nuclear energyNuclear energy is the energy released in nuclearreactions. We also refer to nuclear energy as the energy by which we get other energies such as electric, thermal or mechanical energy from nuclear reactions.
  10. 10. Thermal or calorific energy Thermal energy is heat energy produced by burning a fuel, which may be solid, liquid or gaseous, also obtained by electricity, by friction, by nuclear fission ...This energy is generated by the movement of the particles forming the subject. Thermal energy is the result of adding all the mechanical energy associated with themovements of the different particles that form and unit of thermal energy is heat. In the thermal energy, there are 2 types: the heat energy and solar thermal.
  11. 11. Energy sourcesRenewable energyNon renewable energy
  12. 12. Renewable energy It is called renewable energy to the energy obtained from natural sources inexhaustible, or the immense amount of energy they contain, or because they are able to regenerate by natural means.
  13. 13. Non-renewable energyNon-renewable energy refers to those sources of energy found in nature in a limited amount and once consumed in its entirety can not be replaced, because there is no production or extraction system viable.

  15. 15. POWER STATIONSA power plant is a plant where some kind offuel is used in order to produce electricity.In this way there are: thermal plants (usingsteam or gas turbines), hydroelectric (usingwater power by means of hydraulic turbinesand generators with automated operation),nuclear, wind (using wind energy) and solar(solar energy).
  16. 16. ABOUT WIND TURBINES THAT PRODUCE FRESH WATERThis report explains the process of how fresh water can be produce from humid air by using wind turbines. This project is very important, because if it’s carried out, it could solve many problems, for example: islands cannot centralized their water supply, or some remote communities in arid countries where water resources are scarce.
