Question

Which energy source is considered non-renewable?

• A. Solar energy
• B. Wind energy
• C. Nuclear energy
• D. Bio-energy

Hint:

Logic Tip: Ask yourself: "Can I grow more of it, or wait for the sun/wind to bring me more?" If the answer is no (you have to dig it out of the ground until the hole is empty), it is non-renewable.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Renewable energy comes from sources that are naturally replenished on a human timescale. Non-renewable energy comes from sources that will eventually run out or take millions of years to form.
Step 2: Key Formula or Approach:
Categorize the sources:
Renewable: Solar, Wind, Hydro, Bio-energy, Geothermal.
Non-renewable: Fossil fuels (Coal, Oil, Gas) and Nuclear.

Step 3: Detailed Explanation:
While Nuclear energy is "clean" in terms of carbon emissions, it is considered non-renewable because it relies on uranium ore found in the Earth's crust. There is a finite supply of uranium; once we mine and use it all through fission, it cannot be replaced. Solar, wind, and bio-energy rely on the sun and natural cycles that are effectively infinite.
Step 4: Final Answer:
Nuclear energy is the non-renewable source among the options.
