Top  5 Examples Of Sustainable Energies


As we know the source of non-renewal energy is limited in our world.Once it's finished we can't recycle it. But the need of energy  always will be there.So recent days scientists are finding the sources of sustainable energy.
          These energy sources are reusable, does not pollute our environment. Use of sustainable energy is under developed. But in the future the source of unsustainable energy will be finished so we will be dependent on sustainable energy. 

Here are 5 well known sustainable energy sources-

1. Solar Energy:

    Solar energy means the energy that comes from the sun . It is a popular source of sustainable energy. Solar energy is absorbed by solar panels. Later it is used for various purposes. We can also store solar energy. The processing of solar energy is very costly. But as the technology develops the cost will decrease and it will be used world wide. Some of the application of solar energies are solar heater , solar calculator, solar charger, solar car etc.

2. Wind Energy:

      The energy that we get from the wind is called wind energy. We use the speed of the wind to get the energy. To convert wind into energy we need to make wind mills. The wind mills will move in a circular motion and the energy will be created. We need high speed wind to produce wind energy. So, wind energy can be produced only where the speed of the wind is very high.

3.Ocean Wave Energy:

     Ocean waves hit the shore with enormous power. We can produce energy from waves. Wave energy can satisfy the 40% need of world's energy. But we are not able to use the full potential. Ocean wave energy does not pollute the environment and it's free for lifetime. 

4. Biomass:

       We can produce  energy from animal waste. This energy is called biomass. First we dig a hole inside the ground. Then we store the animal waste inside the hole and cover it. We left it for some days. After that a gas is released from the waste. It's called the bio gas. Most of the gas contains methane. Bio gas works as a good fuel.


5. Nuclear Energy:

              The energy that we get from nuclear fission is called the nuclear energy. Nuclear fission means when a bigger particle of an element breaks into two comparatively smaller particles of elements. In this process a lot of energy is released . This energy is called the nuclear energy. 1 gm. of nuclear energy of Uranium is equal to 2.5 million times energy produced by burning 1 gm of coal. This process of producing nuclear energy is still developing. Once this source is developed this will be one of the main source of energy.
