Which of the following is the non conventional source of energy

Options

A. Coal
B. Petroleum
C. Electricity from nuclear power pbnts
D. Solar radiations

Answer

To determine which of the following is a non-conventional source of energy, we need to understand the definitions and characteristics of conventional and non-conventional energy sources.

### Step-by-Step Solution:

1. **Understand Conventional vs Non-Conventional Energy**:
- Conventional energy sources are typically fossil fuels (like coal, oil, and natural gas) and nuclear energy. These sources are finite and can be depleted over time.
- Non-conventional energy sources are renewable and can be replenished naturally. They include solar energy, wind energy, hydro energy, geothermal energy, and biomass.

2. **Identify the Options**:
- Look at the options provided in the question. Common examples of non-conventional sources include:
- Solar energy (from the sun)
- Wind energy (from wind)
- Hydroelectric energy (from water)
- Geothermal energy (from heat within the Earth)
- Conventional sources would include coal, petroleum, and nuclear energy.

3. **Analyze Each Option**:
- If the options include solar energy, wind energy, hydro energy, or geothermal energy, these are all non-conventional sources.
- If the options include coal, petroleum, or nuclear energy, these are conventional sources.

4. **Select the Correct Answer**:
- Based on the analysis, identify which option fits the definition of a non-conventional source of energy. For example, if "solar energy" is one of the options, it is the correct answer.

5. **Conclusion**:
- After evaluating the options, the correct answer is the one that represents a renewable source of energy, such as solar energy.
