Non Renewable Energy

Energy exist freely in nature, some of them are infinitely available called renewable, and some are infinity called as non-renewable. A non-renewable is that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames.

The non-renewable energy is energy from fossil fuels such as coal, crude oil, natural gas and uranium. Unlike renewable energy, non renewable energy need human intervention to make it suitable for consumption. Fossil fuels are mainly made up of Carbon. It is believed that fossil fuels were formed over 300 million years ago when the earth was a lot different in its landscape.

Non-renewable Energy Resources

The resources for non-renewable energy are mainly fuels from fossil deposit. The most commonly non-renewable resources are:-

Coal

Coal

Petroleum products

Petroleum products

Compressed natural gas

Types of non-renewable energy

Non-renewable energy is mainly the fossil fuels. Apart from fossil fuels, nuclear fuels are also non-renewable.

Fossil Fuels

Fossil Fuels are formed by the remains of animals and plants. Fossil fuel is divided into three categories and is stated below:

Natural Gas Coal Oil
The process of decomposition is longer as it is conducted to high amounts of pressure and heat. It is formed by the decomposition of trees, plants and ferns which hardened due to pressure and heat. Due to excessive pressure, smaller organisms like zooplankton and algae are decomposed into an oil.

Nuclear fuels

The use of nuclear technology relying on fission requires Naturally occurring radioactive material as fuel. Uranium, the most common fission fuel, and is present in the ground at relatively low concentrations and mined in 19 countries. Nuclear power provides about 6% of the world’s energy and 13–14% of the world’s electricity.

Advantages of non-renewable energy

  • The non-renewable source of energy is affordable. For instance diesel and oil.
  • It is easily accessible and more compatible.
  • The non-renewable source of energy is easy to store.

Disadvantages of non-renewable energy

  • Non-renewable energy cannot be replaced once their energy source is used up.
  • The by-products of non-renewable energy cause environmental damages. It also increases greenhouses gases.

Practise This Question

The reason we are not crushed under the weight of air is, that the pressure inside our body is equal to the atmospheric pressure and cancels the pressure being exerted from outside.
