Question

Which of the following is NOT a renewable energy source?

• A. Nuclear
• B. Solar
• C. Wind
• D. Tidal

Hint:

Think of the "Fuel Tank." Renewable sources like the wind or sun have an endless refill. Nuclear energy uses uranium from the ground—once that "tank" is empty, it's gone for good.

Answer 1

The Correct Option is A

Energy sources are classified as renewable or non-renewable based on whether they can be naturally replenished on a human timescale. 1. Renewable Energy Sources: These sources are virtually inexhaustible because they are constantly replenished by natural processes.

• Solar: Derived directly from the sun's radiation.

• Wind: Generated by atmospheric pressure differences caused by the sun.

• Tidal: Driven by the gravitational pull of the moon and sun.

2. Why Nuclear is Non-Renewable:

Nuclear energy is considered a non-renewable source. Although it is a low-carbon alternative to fossil fuels, it relies on

Uranium or Thorium as fuel.

• These elements were formed in stars billions of years ago and exist on Earth in a finite, fixed quantity.

• Once the economically viable uranium ore is mined and consumed through nuclear fission, it cannot be replaced.

3. Conclusion: While extremely powerful and efficient, the finite nature of the fuel source means nuclear energy does not meet the definition of a renewable resource.
