Answer 2

This is a complex topic.  To research the links for you would take me hours.  It is a better learning process for you to do it on your own.

I assume by petrol, you mean gasoline.

Gasoline, easy to produce and very flammable.  High density of energy.

Diesel, easy to produce and not as flammable.  Higher energy density than Diesel.  Bio fuels can be substituted for use in Diesel engines.

Electric,  One of the MOST efficient form of energy conversion machine that we have today are electric motors that takes electricity.  Thus, it is the cleanest form of energy.  But there are vaious of ways producing it, so some of it are dirty (like Coal, oil or arguablely nuclear) and some of it are very clean like Solar and Wind.

Steam is very clean.  But it take a heat source and a lot of water to generate steam in the first place.  We still use steam almost in all the major power generation and propation.  Nuclear submarine, aircraft carriers and nuclear power plants all use steam turbines.
