We use different forms of energy in our daily life.

 

We use 

  • Heat Energy to cook food
  • Electrical Energy to run TV, Refrigerator
  • Mechanical Energy to Walk
  • Chemical Energy to run our Vehicles

 

And to get this Energy, we need a source.

 

Like

  • Heat Energy to cook food comes from burning the LPG Gas in our homes.
    So, LPG is an Energy Source

  • Electrical energy to run TV comes from the Power Plant. The Power plant can be Hydroelectric (generated from water), or Thermal (generated from Coal) or Solar

  • Mechanical Energy to walk comes from our body

  • Chemical Energy to run Vehicles comes from burning Petrol

 

So, the Energy comes from different sources.

 

We can say that some sources are - Conventional, or Non-Conventaional

 

Conventional Sources of Energy means those sources which we have been using since a long while (like burning coal, wood)

Non-Conventional Sources of Energy means those sources which are newly discovered, which we have just started using.

 

Let’s learn more about Conventional and Non-Conventional Sources of Energy

 

There are also other Basis of Classification, like Renewable and Non-Renewable Sources

 

Renewable Sources of Energy

Renewable Sources of Energy are those sources of Energy which can be renewed again and again.

That means, those Sources of Energy which cannot be exhausted after multiple uses is called Renewable Sources of Energy

 

For example

  • Solar Energy - Solar Energy comes directly from the sun and Sunlight is not exhausted anytime soon
  • Wind Energy - When we use Wind Energy, it won’t get finished on using. So, Wind energy is Renewable

 

Non-Renewable Sources of Energy

Non-Renewable Sources of Energy are those sources which will get finished on using.

 

Example

  • Fossil Fuels like Coal, Petroleum, Petroleum Gas will get exhausted very soon
  • Natural Gas
