Question

Which of the following is not an advantage of hydroelectric energy?
(A) Flowing water is found everywhere. So hydro energy can be obtained easily.
(B) It is a renewable source of energy.
(C) It does not cause any pollution.
(D) All of the above.

Answer 1

Hint: Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources.

Complete step by step answer:
Hydroelectric energy or hydroelectricity is a form of energy that uses the power of moving water, such as a waterfall, to generate electricity. It is a form of renewable energy; it mostly uses water stored in dams and also the one flowing in rivers to generate electricity in hydropower plants. A hydroelectric power station converts the kinetic, or movement, energy in flowing or falling water into electrical energy that can be used in homes and businesses.
Due to its high construction cost, it is not easy to construct a hydroelectric power plant anywhere. One needs to look for various factors that are in favor of the construction process. Hence, even after having flowing water everywhere, hydro energy cannot be obtained easily.

Therefore, the correct option is (a).

Additional information:
1. With its wide range of advantages, hydroelectricity has some disadvantages too:
2. Due to damming of water, we are intervening in the natural existence of the environment.
3. The construction cost is very high.
4. Droughts may affect the working.
5.Due to limited reservoirs, it cannot be constructed at all the locations.

Note:
Hydroelectric energy has a lot of advantages:
1. It is renewable.
2. It is pollution-free.
3. It is a very reliable energy.
4. It is very flexible.
5. Since there are no fuels involved, it is very safe.
