Question

What type of energy source is hydroelectric energy ?

• A. Renewable
• B. Non-renewable
• C. Both (A) and (B)
• D. None of these

Hint:

To easily identify renewable sources, think about whether the source is naturally and quickly replenished. Sun shines, wind blows, water flows, and plants grow—all are renewable. Fossil fuels are formed over millions of years, making them non-renewable on a human timescale.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Energy sources are classified as renewable or non-renewable.
Renewable sources are those that are replenished naturally over a relatively short period. Examples include solar, wind, hydro, geothermal, and biomass.
Non-renewable sources are those that are finite and are consumed much faster than they are formed. Examples include fossil fuels (coal, oil, natural gas) and nuclear fuel (uranium).

Step 2: Detailed Explanation:
Hydroelectric energy is generated from the kinetic energy of flowing water or the potential energy of water stored in a dam.
The water used in this process is part of the Earth's water cycle, which is driven by solar energy. Rain and snow replenish the rivers and reservoirs.
Since the water cycle is a continuous and natural process, hydroelectric energy is considered a renewable source of energy.

Step 3: Final Answer:
Hydroelectric energy is a renewable energy source.
