SOURCES OF ENERGY

Energy can neither be CREATED nor be DESTROYED. It can only be transformed from one form to another.

Characteristics of a good source of fuel :

1) It should have a high energy output per unit mass or volume.

2) It must be easily accessible.3) It must be easy to store and transport.4) It must be economical.

ACTIVITY:CREATE YOUR OWN ENERGY MASCOT…!!

It’s learn more about fossil fuels……..

Are you ready ^.^

Hydro power plant.* In hydro power plant we generate electricity with the help Of water.

* Potential energy of water stored at heights is converted into Kinetic energy of flowing water which in turn is converted into Electricity.

* Renewable source of energy.

* Not many natural waterfalls for this , so dams are constructed.

* Dams are nothing but a kind of obstruction in a water body. Dams will create reservoir to store water at a height.

Hydroelectric generation Process.

* Dams obstruct water flow.

* Water gets collected in big reservoir at a height.

* Kinetic energy of water gets converted into Potential energy.

* Water from high-level carries to lower level dam Where turbine is located.

* Kinetic energy of water thus runs the turbine.

* Then, electricity is produced.

Disadvantages of damsConstruction.

* Large areas of agricultural lands need to be sacrificed.

* Huge human habitation is compromised.

* Large ecosystem are destroyed when submerged under the water in dams.
