Where does the earth get its energy from? The answer is very simple: from Sun.

Almost all of the earth’s energy comes from the Sun. All the plants make their food through the process of photosynthesis with the help of the sun. This is why all life on earth depends on solar energy.

Since the beginning of the times, plants made their food with the help of the sun and animals eat these plants or other animals as food. This is how the whole food cycle ran based on the Sun. Over the course of a million years, the plants and animals that died became fossil fuels.

There are some places on earth that are warmer than the others because of the amount of heat these places receive from the sun throughout the year. This heat from the sun causes winds.

The water cycle is also based on the sun because the heat from the sun moves water on the surface of the earth. People harness this energy for their use.

What are energy resources?

Everything requires energy to operate. Even if a person is sitting still and doing nothing their body is still performing basic tasks like blood circulation, food breakdown, breathing, and even the blinking of eyes. All of these basic functions performed by the human body also require energy to be executed.

Plants and animals on this planet function somewhat like humans. They look for/prepare their food using energy. Production of heat and light requires energy. In short, every little task requires energy to be performed.

Types of energy sources

There are two types of energy sources.

  • Renewable energy sources
  • Non-renewable energy sources.

Renewable energy sources are the sources of energy that can be renewed or recycled as soon as they are being used. This is why these sources are hoped to be available for many generations to come.

However, non-renewable energy resources are not recyclable or renewable. This is why these energy sources are feared to run out because they are just being consumed and not being recycled.

There are many types of non-renewable energy sources on earth some are as follows;


Coal is a solid form of fossil fuel that is formed when ancient forests are decomposed. It is used to produce electricity by burning it. The use of coal is being preferred worldwide since it is plentiful under the surface of the earth.

It is cheaper than oil and gas which are decreasing by the day. Coal is formed by dead forests which are settled at the bottom of the ancient swamps.


Oil is a liquid fossil fuel. It is extremely useful because it is used in transportation and can easily be extracted out of the earth and transported. Oil is one of the largest sources of energy in the world.

Oil first extracted from the ground is called crude oil. Crude oil is a mixture of a number of hydrocarbons.  It is thick in volume and is black in color. Oil is produced when small organisms that live on the surface of the earth die and sink down to the seafloor.

These layers of dead organisms keep piling up without any oxygen. Heat and pressure keep increasing and this is how these dead organisms turn into liquid crude oil.

Natural gas

Natural gas which is commonly known as gas is a composition of hydrocarbon methane. It is formed under the same circumstances through which oil is formed.

Organic material is buried underneath the surface of the earth and heat and pressure increase with time. This organic material buried in the sediments becomes hard and as a result shale forms which is the source of the gas.

Natural gas is formed at higher temperatures as compared to crude oil and coal. However, crude oil and natural are often found at the same place simultaneously.

Solar power, water, and wind are other renewable energy sources on earth. These sources can be renewed with a number of natural and man-made ways like water can be recycled. Solar power will be there as long as the sun is and the wind will also keep blowing because of the heat from the sun.
