Which of the following is a renewable source of energy?

Options

A. Coal
B. Petroleum
C. Natural gas
D. Solar energy

Explanation

To determine which of the following options is a renewable source of energy, we need to analyze each option provided:

1. **Identify the Options:**
- Option A: Coal
- Option B: Petroleum
- Option C: Natural Gas
- Option D: Solar Energy

2. **Define Renewable and Non-Renewable Energy Sources:**
- **Renewable Energy Sources**: These are energy sources that can be replenished naturally over a short period of time. They are considered inexhaustible as they can be used repeatedly without the risk of depletion. Examples include solar energy, wind energy, and hydroelectric energy.
- **Non-Renewable Energy Sources**: These are energy sources that exist in finite amounts and take millions of years to form. Once consumed, they cannot be replaced within a human timeframe. Examples include coal, petroleum, and natural gas.

3. **Analyze Each Option:**
- **Coal**: This is a fossil fuel that takes millions of years to form and is therefore a non-renewable resource.
- **Petroleum**: Similar to coal, petroleum is a fossil fuel formed over millions of years and is also non-renewable.
- **Natural Gas**: Like coal and petroleum, natural gas is a fossil fuel and is non-renewable.
- **Solar Energy**: This energy comes from the sun and is continuously available. It is renewable because it can be harnessed repeatedly without depleting the source.

4. **Conclusion:**
- Based on the analysis, the only renewable source of energy among the options provided is **Option D: Solar Energy**.

**Final Answer: Option D: Solar Energy is a renewable source of energy.**
