The energy which we obtain from the sun is called solar energy or radiant energy. The sun's energy is stored in coal, natural gas, water and wind. Coal, oil, and natural gas are known as fossil fuels.
Fossil fuels were formed over millions of years ago when the remains and fossils of prehistoric plants and animals sank to the bottom of swamps and oceans. These animal and plant remain were slowly covered and crushed by layers of rock, mud, sand, and water. The pressure of all those layers caused the plants and animals to break down and change into coal, oil and natural gas. We use the energy in these fossil fuels to make electricity. As of the year 2019, most of the energy we use comes from fossil fuels. However, fossil fuels are known as non-renewable sources of energy. They cannot be used over and over again. This means that one day they will run out!
Which of the following statements is correct?

Options

A. Energy obtained from fossil fuels is renewable.
B. Energy obtained from the sun is solar energy.
C. Coal and natural gas are examples of nuclear energy
D. Wind energy is not renewable.

Answer

To determine which statement is correct based on the information provided about fossil fuels and energy sources, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Fossil Fuels**:
- Fossil fuels include coal, oil, and natural gas. They are formed from the remains of prehistoric plants and animals that were buried under layers of rock, mud, and sand over millions of years. The pressure and heat from these layers transformed the organic remains into fossil fuels.

2. **Evaluating Statement A**:
- **Statement A**: "Energy obtained from fossil fuels is renewable."
- **Analysis**: Fossil fuels are classified as non-renewable sources of energy because they take millions of years to form and cannot be replenished quickly. Therefore, this statement is **incorrect**.

3. **Evaluating Statement B**:
- **Statement B**: "Energy obtained from the sun is solar energy."
- **Analysis**: The energy from the sun is indeed referred to as solar energy. This statement is **correct**.

4. **Evaluating Statement C**:
- **Statement C**: "Coal and natural gas are examples of nuclear energy."
- **Analysis**: Coal and natural gas are fossil fuels, not nuclear energy. Nuclear energy is produced through nuclear reactions, such as fission. Therefore, this statement is **incorrect**.

5. **Evaluating Statement D**:
- **Statement D**: "Wind energy is non-renewable."
- **Analysis**: Wind energy is a renewable source of energy as it can be harnessed repeatedly as long as the wind blows. Thus, this statement is **incorrect**.

### Conclusion:
After evaluating all the statements, the only correct statement is **B: Energy obtained from the sun is solar energy**.
