1. ENERGY

2. GEOTHERMAL

3. ENERGY FROM VOLCANO

4. GEOTHERMAL ENERGY heat or thermal energy that is stored deep within the earth(core) that originates from the melted molten rock and the decay of radioactive substances. considered high renewable energy source because the water is replaced by rainfall and the heat is continuously produced by the earth.

5. occurs in the ring of fire zone of pacific volcanoes

6. Philippines is the third largest producer of geothermal energy in the world.

7. Active volcano have high geothermal energy system. Because the hot molten rock material located under the earth’s surface may heat the circulating groundwater.

8. HOW DOES ENERGY WORK?

9. Energy is generated by carrying heat to the surface via fluid circulation through various types of mechanics.

10. The main energy transformation that occur in geothermal power stations are thermal energy found in geothermal reservoir converted to mechanical energy from the steam towards a turbine and then to electrical energy by the generator.

11. A geothermal power plant uses steam through a geothermal reservoir. A geothermal reservoir is an underground pool of water of hot water found below the earth’s surface. The geothermal power plant undergoes a series of steps to produce electricity for human consumption.

12. STEPS TO PRODUCE ELECTRICITY

13. 1. HEAT FROM THE EARTH’S CRUST CREATES STEAM 2. STEAM ROTATES TURBINE

14. 3. GENERATOR PRODUCES ELECTRICITY 4. WATER IS INJECTED BACK INTO THE GROUND

15. How does geothermal energy works? 1.Wells are drilled deep into the earth to pump steam or hot water to the surface 2.When the water reaches the surface, the drop in pressure causes the hot water to turn into steam.

16. 3.The steam produced spins the turbine. The mechanical energy caused by the spinning of the blades of the turbine is used to spin magnets and generate an electric current in the generator. 4.The cooling tower cools the steam which condenses back to the water.

17. 5.The cooled water is pumped back into the earth to begin the process again.

18. TYPES OF GEOTHERMAL POWERPLANT 1. DRY STEAM - IT REQUIRES THE HIGHEST AMOUNT OF TEMPERATURE

19. 2. FLASH CYCLE - REQUIRES LESS TEMPERATURE ABOUT 180 C AND UTILIZES A FLASK TANK

20. 3. BINARY CYCLE - REQUIRES A LOWER TEMPERATURE THAN FLASH CYCLE

21. Examples of geothermal power plants in the country: Tiwi geothermal power plant in Tiwi, Albay Mak-ban(Makiling banahaw) Geothermal Power plant in Calawang, Laguna Palinpin geothermal power plant in Valencia, Negros Occidental

22. Bac-man (bacon manito) geothermal power plant in Bacon, Sorsogon Mt. Apo geothermal power plant in Kidapawan City, North Cotabato

23. Illustrate how does geothermal energy work.

24. Write true if the statement is correct and false if it is not. 1.Geothermal energy is an energy that is stored deep within the earth(core) that originates from the melted magma and the decay of radioactive substances.

25. 2.Inactive volcano have high geothermal energy system. 3.Most geothermal energy on the world occurs in the ring of fire zone of pacific volcanoes.

26. 4.Makiling-banahaw is located at Tiwi. 5.Mt. Apo geothermal power plant is located at Leyte.

27. why or how on the last column. Y ES No Write your reason at least 1 or 2 sentences 1. Is the Philippines rich in geothermal energy? 2. Is building a geothermal power plant is much cheaper than solar power plant. 3. Is geothermal energy safer than most other energy sources? 4. Can the Philippines sustain its geothermal energy source? 5. Can we use Geothermal energy in our daily life?

28. ASSIGNMENT WHAT IS CLIMATE CHANGE?
