Future Energy Sources

Future Energy Sources

What does the future hold? How will we generate electricity when we run out of coal, oil, and natural gas. Many scientists are looking for answer of above question.
The energy is defined typical tree parts conventional, nuclear and alternative energy.

 

1. Conventional energy

Fossil fuels are called conventional energy which is coal, oil and natural gas.
They are unkindly natural environment. Also they will be exhaustion in near future so scientist research and development alternative fossil fuels.

 

2. Nuclear energy

Nuclear energy is made of nuclear fission. Then we use particular mineral. That is called “Uranium”. Nuclear energy is more efficient than fossil fuels. But they have weakness. Which are explosion, radioactivity in danger and Uranium is also limited resource.

 

3. Alternative energy

Alternative energy has to satisfy with three conditions. Which are Renewable, Friendly natural environment and unlimited resource. So alternative energy is called green energy

They are biomass, vegetable oil and geothermal, hydroelectric energy and wind, solar power and the others.
