What are the types of energy sources available in the world?

In this world, there are many kinds of energy sources.

The energy sources can be split into 3 groups.

- Fossil Fuels

- Nuclear

- Renewable

--------------------------------------------------------------

Fossil Fuels

Fossil fuels have been a widely used source of energy since before the dawn of the 20th century. Fossil fuels are popular because they are easy to use to generate energy for the only require a simple direct combustion. However, fossil fuels leads to a great deal of air pollution.

There are 3 types of fossil fuels.

~ Coal

~ Petroleum/ Crude Oil

~ Natural Gas

-----------------------------------------------------------------------

Nuclear Power

The diminishing availability of natural resources such as coal, petroleum, and crude oil has left scientists searching for an energy alternative. For the time being, the power of the atom seems to be the only solution.

These are the 2 types of nuclear power

~ Fission

~ Fusion

Fission research into lessening problems caused by reactors is of great concern to many, while fusion has risen to the forefront of future energy research.

-----------------------------------------------------------------------

Renewable

The 'renewable' energy sources is getting more important due to the uncertainty of the future of fission research.

The main types of renewable sources are

~ Hydroelectric

~ Solar

~ Wind

~ Biomass

~ Geothermal

In light of diminishing fossil fuels, however, renewable energy may end up as the energy of choice for the 21st century.
