Question

Hydroelectric power plant utilizes the energy of

• A. flowing water
• B. moving wind
• C. burning fossils fuels
• D. solar energy

Answer 1

The correct option is A

flowing water

The explanation of the correct option:

1. In the hydropower plant, hydropower is used and this is the power associated with the flowing water.
2. Energy of flowing water is called Hydropower. The power plant which uses hydropower is termed a hydropower plant.
3. In a hydropower plant, the hydropower is converted into electrical power.

The explanation for the incorrect options:

1. Wind energy is used for moving the turbine of the wind power plant. Thus, it is not used in hydropower plants.
2. Burning fossil fuels produce a lot of heat. This heat is used to convert water into steam in a thermal power plant. Thus, it is not used in hydropower plants.
3. Solar energy is used indirectly in hydropower plants to maintain the water cycle. But it is not directly used in hydropower plants.

Hence, the correct option is (A).
