What are some advantages of hydroelectric generators?
Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water. Hydropower is affordable. Hydropower provides low-cost electricity and durability over time compared to other sources of energy.
What are some environmental disadvantages of hydroelectric power?
Hydropower has the ability to generate electricity without emitting greenhouse gasses. However, it can also cause environmental and social threats, such as damaged wildlife habitat, harmed water quality, obstructed fish migration, and diminished recreational benefits of rivers.
Which of the following is disadvantage of hydropower Mcq?
They are not Non-renewable because water is inexhaustible. It is not continuous source of energy because its output fluctuates with change in flow rate of water with season.
Why are hydroelectric dams bad?
Hydropower dams degrade water quality along rivers. Water that flows downstream from the dams is depleted of oxygen, which harms many aquatic animals. The reservoirs above dams are susceptible to harmful algal blooms, and can leach toxic metals such as mercury from submerged soil.
What are the effects of hydroelectric power?
Hydropower does not pollute the water or the air. However, hydropower facilities can have large environmental impacts by changing the environment and affecting land use, homes, and natural habitats in the dam area.
Which of the following is a disadvantage of renewable energy?
The correct answer is option (B) Unreliable supply. The major disadvantage of renewable energy sources is the unreliable supply.
What is hydroelectric power?
Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
Which of the following is not a part of hydroelectric power plant?
Explanation: Sedimentation is not a constituent of a hydro power plant. Usually a dam, water reservoir, intake and control gates, water turbines and penstack are some of the components that are used in major parts of a hydro electric power plant.
