Which of the following is not a non-renewable energy source?Options :Wind energyPetroleumCoalNatural gas

To determine which of the options is not a non-renewable energy source, we need to understand what non-renewable energy sources are. Non-renewable energy sources are those that cannot be replenished or regenerated within a human lifespan or at a rate that is sustainable for future generations.

Let's analyze each option:

1. Wind energy: Wind energy is a renewable energy source. It is generated by harnessing the power of wind to produce electricity. Since wind is a natural occurrence that will continue to exist, wind energy is considered renewable.

2. Petroleum: Petroleum, also known as oil, is a non-renewable energy source. It is formed from the remains of ancient plants and animals that have been subjected to heat and pressure over millions of years. Once extracted and used, petroleum cannot be replaced within a human lifespan.

3. Coal: Coal is another non-renewable energy source. It is formed from the remains of plants that lived and died millions of years ago. Like petroleum, coal takes a long time to form and cannot be replenished within a human lifespan.

4. Natural gas: Natural gas is also a non-renewable energy source. It is formed from the remains of ancient plants and animals, similar to petroleum and coal. Once extracted and used, natural gas cannot be replaced within a human lifespan.

Based on this analysis, wind energy is the option that is not a non-renewable energy source.
