  1. 1. Names: Sofía de la Cruz Mario Sánchez Group: 2ºA
  2. 2. Index• Energy definition• Types of energy• Energy sources• Renewable and non-renewable• Enviromental inpact• Energy power stations
  3. 3. • Energy is the capacity of a body to do a work.
  4. 4. • MECHANICAL ENERGY.-Kinetic energy is the energy associated to the movements -Pontential energy is the energy that objects have when they´re moved from their stable position of equilibrium.
  5. 5. • ELECTRICAL ENERGY:The energy associated with an electrical current.• ELECTROMAGNETIC ENERGY:Transported by electromagnetic waves,such as TV.
  6. 6. • SOUND ENERGY:Energy related to the sounds waves transmitted by vibrations.• CHEMICAL ENERGY:Is stored in substances.
  7. 7. • NUCLEAR ENERGY:Is energy released during fission or fusion of atomic nuclei.• THERMAL OR CALORIFIC ENERGY:Is energy that comes from the vibrations of particles.
  8. 8. • Energy sources are natural resources that provide different forms os energy.
  9. 9. • NUCLEAR ENERGY:• -Nuclear fussion is when two nuclei join fprm a heavier nucleus. • Nuclear fission Iis when a heavy nucleus is divided into two smallers nuclei.
  10. 10. • COAL:-Open-cast mines:Coal casts are outdoor-Underground mines:Coal casts are inside the earth and we cannot se its.
  11. 11. • PETROLEUM:-Oil tankers:Specialished ships designed for intercontinental transport.-Oil pipelines.Enormous steelPipes.·NATURAL GAS:Is transported in longs tubes along parts of the earth.
  12. 12. • WORLD RESERVES OF FOSSIL FUELS:
  13. 13. • INCREASED GREENHOUSE EFFECT:Some sun rights bounce off the atmosphere and do not go.
  14. 14. • ACID RAIN: The rain mix with chemical products that spoil all that it touch.Here you have an example:
  15. 15. • OIL SPILLS:These happen when petroleum is accidently released into the sea.• NUCLEAR WASTE:These are very dangerous rpoducts and you must take care with it becouse it can cause you chemical reactions.
  16. 16. • RISING WATER TEMPERATURE:These provoke,for example,the melting on the oceans• ATMOSPHERIC POLLUTION:These occurs when gases are expelled to the atsmosphere.
  17. 17. • HYDRAULIC ENERGY:Is related with the water.Water is transform into energy.• SOLAR ENERGY:Is related with the sun.Sun is transform into energy.
  18. 18. • WIND ENERGY:Is related to the wind.We transform the wind into energy.• MARINE ENERGY:Several means-Tidal energy-Wave energy-Ocean thermal energy
  19. 19. • GEOTHERMAL ENERGY:This energy comes from the heast stored in the earth’s crust.• BIOMASS:Is produced fromPlants remains,forest and agriculturalWaste.·MUNICIPAL SOLID WASTE:This is generated in cities.Comes from domestic activities.
  20. 20. • Possible adverse effects caused by a development, industrial, or infrastructural project or by the release of a substance in the enviroment.
  21. 21. • THERMAL POWER STATIONS:• SOLAR POWER STATIONS:
  22. 22. • NUCLEAR POWER STATIONS:• WIND POWER STATIONS:
  23. 23. • ELECTRIC POWER STATIONS:
