INTRODUCTION
we obtain energy from different sources
Which are non renewable and which emits lot of pollution
so we have to go for a technology that helps us to get energy as well as it should be free from pollution
And also that technology should use renewable sources so that we no need not fear about the source limit.
GREEN ENERGY
Energy obtained from renewable sources is known as “green energy
It is free from pollution so “green energy is also known as “clean energy”
SOLAR ENERGY
The energy obtained from sun is known as solar energy
This energy is converted into electrical energy
Thus we can get more energy
Solar panels are used for this purpose
Wind energy
Wind energy is another source for producing energy
*The pressure of wind rotates turbines for producing electricity
*so it also an important source for energy
To evolve hydrogen
From water , we are able to generate hydrogen gas which is a very useful gas
This system can be engaged in vehicles instead of petrol
The vehicles using such energy is known as “green vehicles”
