Consider the following statements.
1. Hydraulic power can be captured when water flows down from a higher level to a lower level, thereby converting the mechanical energy of water into kinetic energy to drive the generator.
2. Hydropower is the cheapest and cleanest source of energy.
Which of these statements is/are incorrect?
  • a)
    1 only
  • b)
    2 only
  • c)
    Both 1 and 2
  • d)
    Neither 1 nor 2
Correct answer is option 'A'. Can you explain this answer?

Consider the following statements.1. Hydraulic power can be captured ...
Explanation:

Hydraulic power or hydropower is the power derived from the energy of water flowing from a higher level to a lower level. It is a renewable and sustainable source of energy that has been used for centuries to grind grain and power machinery. The statement 1 is correct as hydraulic power can be captured when water flows down from a higher level to a lower level, thereby converting the mechanical energy of water into kinetic energy to drive the generator.

However, statement 2 is incorrect as hydropower is not always the cheapest and cleanest source of energy. Here are some points to support this:

Cost:
- The cost of building a hydropower plant can be high, especially if it involves building a dam or reservoir.
- The cost of maintenance and repair of hydropower plants can also be high.
- The cost of transmission lines to transport the electricity from the hydropower plant to the consumer can also be high.

Environmental impact:
- Building a dam or reservoir can have a significant impact on the environment, including the loss of habitats, displacement of people, and alteration of river ecosystems.
- Hydropower plants can also have an impact on fish migration and water quality.
- Decomposing organic matter in reservoirs can produce methane, a potent greenhouse gas.

In conclusion, statement 1 is correct, but statement 2 is incorrect as hydropower is not always the cheapest and cleanest source of energy.

Consider the following statements.1. Hydraulic power can be captured ...
  • Hydraulic power can be captured when water flows down from a higher level to a lower level, which is then used to turn the turbine, thereby converting the kinetic energy of water into mechanical energy to drive the generator.
  • Hydropower is the cheapest and cleanest energy source, but there are many environmental and social issues associated with big dams, as seen in projects like Tehri, Narmada, etc.
