Non-Renewable Sources of Energy

Non-renewable sources of energy are those sources that cannot be replenished or renewed once they are used up. These sources of energy were formed millions of years ago and are finite. They are also known as fossil fuels, and they include coal, oil, and natural gas.

1. Coal
Coal is a black or brown rock-like substance that is formed from plant matter that has been buried and subjected to high pressure and heat for millions of years. It is the most abundant fossil fuel and is used primarily for electricity generation.

2. Oil
Oil, also known as petroleum, is a liquid fossil fuel that is formed from the remains of dead plants and animals. It is found underground and is extracted using drilling techniques. Oil is used primarily for transportation, heating, and electricity generation.

3. Natural Gas
Natural gas is a fossil fuel that is formed from the remains of dead plants and animals. It is found underground and is extracted using drilling techniques. Natural gas is used primarily for heating and electricity generation.

Why they are Non-Renewable

Non-renewable sources of energy are finite and cannot be replenished once they are used up. They are also environmentally damaging, as their extraction and use can lead to air pollution, water pollution, and habitat destruction.

Conclusion

Non-renewable sources of energy are an important part of our energy mix, but they come with significant environmental and economic costs. As we move towards a more sustainable future, it is important that we transition to renewable sources of energy that are both environmentally friendly and economically viable.
