Eolic energy

1. Eolic energy *Miguel Ángel Rodríguez Sánchez. *Lucía Yánez Arencibia. *Claudia Sánchez Sánchez..

2. whAT IS IT? • Its a kinetic energy. • Wind turbines are used to produce eolic energy.

3. Advantajes • Its a renewable energy • Wind turbines have low cost • High perfomance is achieved • Reduce energy dependency on fossil fuels.

4. Disadvantajes • Intermittent and random • Difficulstorage • Wind turbines are danger to birds • occupy large tracts of land • generateinterference

5. Percentages • Spain= 16% powerconsumption • In theworld= aproximate 20%

6. Coal By: Leandro Domínguez,Pablo Vizcaíno andAndrea Medina.

7. Consist in: Vegetable remainslikeanthracite,coal,ligniteandpeat.

8. Advantage: Cheappower and withhightenergypower.

9. Disadvantage: Very pollution.

10. % used in theworld: 39 . In Spain: 15

11. ENERGy MAREMOTRIZ

12. definition It is the energy that is obtained from tidal movements (sea water)

13. Advantage: it is a clean energy disadvantages: Is necessary a very expensive Technology Depending of the places the differencesare of meters

16. OIL

17. Whatistheoil? • It is the most used energy source. As fuel is more efficient than coal, it has higher calorific

18. Adventage : • It has an easy obtainment. • It is very useful. • It is a quite effective energy.

19. Disadventages: • It is very contaminating. • Produces highly toxic substances such as CO2. • Ocean pollution.

21. HIDROPOWER

22. HYDROELECTRIC PLANT IS TO OBTAIN ENERGY FROM THE WATER STORED IN THE DAM.

23. ADVANTAGES AND DISADVANTAGES ADVANTAGES: HAVE MINIMUM MAINTENANCE, CLEAN DOES NOT GENERATE WASTE AND HELP CONTROL FLOODS AND PROVIDE WATER FOR AGRICULTURE. DISADVANTAGES: THEY ARE FAR FROM LARGE TOWS AND WATER QUANTITY DEPENDS ON TIME, THE CONSTRUCTION OF RESERVOIS INVOLVES THE FLOODING OF THE DAM.

24. IN SPAIN, 75% OF THE POPULATION USES THIS ENERGY AS THAT IN THE WORLD ONLY 14%.

26. NUCLEAR ENERGY BY: Pablo Rubio Santana, Beatriz Ramirez GarcíaandAarón Josué Travieso Reyes.

27. NUCLEAR POWER. MAIN POWER: NUCLEAR POWER STATION

28. MAIN MATERIAL:URANIUM PERCENTAGE USED IN SPAIN: 22% WARNING: DANGEROUS AND HIGHLY RADIOACTIVE. PRODUCES SERIOUS ILLNESS

29. ADVANTAGES: • PRODUCES: • ELECTRICITY

30. DISADVANTAGES • OCCUPY NATURAL • CO2 EMISSIONS • NATURAL DISASTERS • WORSENING ENVIRONMENT • NUCLEAR BOMBS

32. WHAT IS IT? It is the energy that comes from heat stored in the Earth's interior.

33. ADVANTAGE • It produces no waste. • It is inexhaustible on a human scale. • In some countries is to restore use it to produce electricity

34. DRAWBACKS • The location is difficult. • It’s very costly.

35. IN SPAIN AND IN THE WORLD • With regard to renewable energy: • In Spain: 0.05% is used. • In the world: 0.8% is used

36. biomass

37. advantajes • It produce little waste • They are low-polluting • Much of the waste is from human activities

38. Disadvantages Low efficiency energy • It has big volume (hindering manipulation)

39. It`s produced: 3 Forms: -agricultural crop -recycling waste -Chemically transforming plants

40. Natural gas A source of energy

41. is a mixture of gases

42. advantage disadvantages The use of natural gas produced many greenhouse gases are damageable by weather• Natural gas is not a renewable energy source.• It is difficult to store natural gas • can replace coal and oil • as heating • as fuel • produces electricity • highcalorific • cleancombustion

43. All the gas becomes exhausted: Spainspends 21 % of gas In worldspends 56% of gas
