Question

why does the choice of a fuel depend on its availability, efficiency, cost and the amount of pollution caused by it?

Answer 1

efficiency of fuel upon these factors,
1. availability: it should be available
2.cost: it should be low cost
effeciency:it should work longer and better.
amt of pollution: it should be low .so, air pollution can be reduced

natural gas best meet all these needs

Answer 2

The fuel is easily available. If the fuel is not easily available then one it can not be used in large scale. Fuel should be efficient i.e. it should give large amount of energy on burning the small amount of fuel. The fuel should not be much costly. If the fuel would be costly the common people will not be able to use it. Fuel should be eco friendly. It should not produce much amount of pollution on burning. If the fuel produces pollution, then it will create a very big problem for our environment and health.
