Let me just put forward my views:


This is for cars only:

Hydrogen:

While this is the most-hyped (and best-sounding ) alternative fuel, the problem of storing the fuel is not fully sorted (the tank is vulnerable and can explode in adverse conditions ). And also, it will take quite a while to ramp up hydrogen production and build special pumps.
Another problem is that the water released out of the tailpipes will increase the moiusture content in the air, which might have efefcts ont he climate.

Solar Energy:

I think this field will only have oppurtunity if it is highly researched, I have only seen solar power in those bullet-shaped vehicles they hold races for.


Bio-Diesel:

I think this is the most promising field yet.

it uses reprocessed animal fat, which is manufactured from food waste, and does not pollute, and is replenishable, and wont run out.

The only problem is making this fuel in large amounts, which might pose some diffculties.

Fuel cells still cost millions to develop (though their packaging problems have been reduced to a massive extent in the past decade)
