*oxides of Nitrogen,Sulphur released on burning fossil fuels causes acid rain

* this is why we are looking for alternative sources of energy

hope it helps!!!

Answer 2

The conventional source are the fossils or fossil fuels ( like kerosene ,petrol ,diesel and lpg ) are exhaustible ( non renewable )

Fossils takes million years to form , and they can’t be renewable ,
And moreover the combustion of these fuels are creating a lot of pollution resulting in Green house effect ( Co2 and other nitrogenous and sulphur mixed gases )

So we need to look for alternative non conventional sources of energy like
Solar energy , wind mills to create electricity
And alternate fuels like biodiesel ( plants can be regrown ) or renewable

And solar cell should be used for automobiles too !
