summarize the points in the lecturer, being sure to explain how they oppose specific points made in the reading:
A hydropower facility consists of a plant for electricity production and a water reservoir formed by a dam in a river. The dam has gates that can open or close depending on how much water is needed to produce a certain amount of electricity. The electricity is transported through transmission lines to an electric utility company.
Hydropower is very convenient because it can respond quickly to fluctuations in demand. The production of hydroelectricity is increased on hot summer afternoons when power is needed for air conditioners and decreased at night when people use less energy. The reservoir of water behind the dam is stored energy that can support fisheries and provide various forms of water-based recreation for local residents and tourists. Thus, hydropower reservoirs contribute to the local economy and quality of life.
Hydroelectricity is 'clean and green.' Once the system has been installed, the burning of fossil fuels is not required to produce the electricity. Hydropower is good for the environment because it does not release greenhouse gases into the atmosphere nor produce waste that requires special containment, as do other forms of energy production. After the water powers the turbines, it simply returns unchanged to the water cycle.
Hydroelectricity power is also very efficient and relatively inexpensive. The earth's water cycle naturally replenishes the supply of 'fuel' water. Wherever enough rain falls, there will be rivers. If a particular section of river has the right terrain to form a reservoir, it may be suitable for dam construction. Modern hydroelectric turbines can convert as much as 90 percent of the available energy into electricity. In contrast, the best fossil-fuel plants are only about 50 percent efficient.
The author states the benefits of hydro-power facilities, however, the speaker opposes to this view by making contrary arguments and pointing out the disadvantages of hydro-power facilities.
The speaker argues that the hydro power is very convenient. When a dam is built on the river, it can cause some areas to flow. Thus, people who have settled down in the same area for a few years have to move because of the damage. Moreover, he explains the quality of their life is greatly affected. This casts doubt on the author's claim who says hydro power facilities are extremely convenient, and therefore, it contributes to improve the quality of life and the local economy.
Second, according to the lecturer, the hydro power has a long term environmental hazard because silt and other residues are collected in the back of the river. Hence, it produces a toxic metal accumulation, which will cause issues for the future generation. However, the author's disagrees with the lecturer by explaining that hydroelectricity is "green and clean", so it does not cause contamination to the environment.
Finally, the orator opposes to the reading by arguing that hydro power facilities have side expensiveness. Furthermore, rivers will become dry, so birds that eat insect will not have food to eat because of the dryness. Also, fish, such as salmon, will eventually decrease in numbers too. Depict the fact water is a renewable source, it depends on weather patterns variation, and thus, it is not a reliable source of fuel. This casts doubt upon the author's opinion who says the hydroelectricity is very effective, inexpensive and reliable source of fuel.
