15. OBJECTIVES Define hydroelectric energy; Identify some hydroelectric power plants in the Philippines Describe the process involved hydroelectric power plants; and Determine the advantages and disadvantages of hydroelectric energy.

16. Almost 40% generated by hydroelectric energy.

17. Hydroelectric Powerplant Place the model in a stable location. Pour water into the reservoir, allowing it to flow through the turbine. Observe the LED light illuminate or the fan spin, demonstrating the generation of electricity by the hydroelectric power plant model.

18. Hydroelectric Powerplant How does a hydroelectric power plant generate electricity? What are the main components of a hydroelectric power plant?

19. Components of Hydropower Plant A dam creates a large waterfall and stores enough water to supply the plant at all times.

20. Components of Hydropower Plant A penstock channels water from the reservoir to the turbines.

21. Components of Hydropower Plant A powerhouse that houses the turbines driven by the waterfall and the generator driven by the turbines.

22. TYPES OF HYDROPOWER PLANTS Impoundment Facility Run-of the-river Plants Pumped Storage Facility

23. QUESTIONS 1. Which of the type of hydropowerplants has greatest advantage in terms of efficiency in generating electricity? Explain your answer 2. What about the one having the least advantage in efficiency? How do you say so? 3. In building the dams for hydropower, what do you think is/are the advantage/s aside from power generation? Disadvantage/s?

24. ADVANTAGES It is beneficial to the environment. DISADVANTAGES It is a sustainable resource. It is adaptable. It is dependable and efficient. It is also cost-effective It has an impact on the environment. It causes people to be displaced. Reservoirs are limited There are droughts It is costly.

25. Quiz Choose the letter of the correct answer. 1. Which of the following power plants uses water to generate electricity? A.Calaca Thermal Plant C. Tiwi Plant B. Agus 1 D. Bataan Plant

26. Quiz 2. Which of the following are factors in generating hydropower? I. Amount of precipitation II. Height of the source III. Density of substance IV. Steepness of slope A. I, II and III only C. II, III, and IV only B. I and II only D. I, II, III and I

27. Quiz 3. Which of the following types of hydropower relies more on the natural water flow rates, diverting just a portion of river water through turbines, sometimes without the use of a dam or reservoirs? A. Impoundment facilities C. Pumped storage system B. Run-of-river facilities D. All the above

28. Quiz 4. Hydropower plants are completely free of greenhouse gas emission. The statement is: A. True, because hydropower is a renewable energy resource. B. True, because power generation is dependent on water cycle only. C. False, because carbon gas emission occurs during construction. D. False, because the energy conversion depletes the oxygen content of the water.

29. Quiz 5. The disadvantage of hydroelectric power station. A. The highest initial cost compared to other types of plant. B. It involve high capital cost due to construction of dam. C. There is a problem in starting the unit. D. The overall efficiency is low (20%).

30. EXTEND Design and build a simple diorama that shows the processes involved in a geothermal or hydroelectric power plant. Your diorama should showcase the different parts of hydroelectric power plants by putting labels for each. Use recycled materials or those materials that can easily be found in your home or community. Pay attention to details and make your representations drawn to scale. You may try to look on the web as your reference to give you more idea on what you will do.

31. The End Do you have any questions?
