18. Geothermal Energy

19. Energy from Volcano

20. Energy Exists in many different form. Ability to do work. Can be stored but never really destroyed. It is just transferred from one form to another, doing work in progress.

21. Energy from Volcano The molten rock (magma) in the Earth's crust that drives volcanic eruptions can also provide heat for electricity generation.

22. Energy from Volcano Geothermal energy “geo” – Earth “ therme ” - heat derived from heat within the Earth's crust.

23. Ranks 2 nd in the world’s production of geothermal energy.

24. Energy from Volcano energy comes from the Earth’s interior through active and volcanic eruption Geothermal Energy

25. According to Department of Energy, 14.4% of the country’s total power of generation is produced from the geothermal energy.

26. The production of energy is cheaper than the electricity production using natural gas, coal, and hydropower.

27. DID YOU REMEMBER SOMETHING? Let’s try what you have remember.

28. PASS THE BOX! The students will pass the box and when the music stop the student who have the box will get one question inside the box and answer the question.

29. Multiple Choice Direction: Read the question carefully and choose the best answer.

30. What is the meaning of the prefix “geo”? Nature Earth Oceans Volcanoes

31. 2. What energy comes from the Earth’s interior? Wind energy Solar energy Geothermal energy Hydroelectric energy

32. 3 . Which of the following activities show awareness of the existence and importance of geothermal energy? Understand that this energy are renewable, reliable and environmentally friendly. Ignored and don’t care about it. Be wasteful of the electricity because there is an alternative source. Study the geothermal energy, its usage as well as its advantage and disadvantages in human and the community. A. I,II,III,IV B. I,III,IV C. I only D. I and IV

33. 4. Where did we can only generate geothermal energy? Ocean Well Stream Volcano or volcanic regions

34. 5. According to the Department of Energy, how many percent of the country’s total power generation is produced from geothermal energy? 16.4% 13.4% 14.4% 44.4%

35. THANK YOU!
