Oil's biggest advantage is the billions of tons lying around,
the oil in your car took millions of years to become oil, but we don't have millions of years to fill the next tank so we have to make the energy ourselves instead of just collecting, we have to be energy farmers not hunters.

Nuclear is probably by far the safest and most versatile type of power that you can put anywhere, but here in Iceland we have lots and lots of energy from hydro and geothermal plants, if only we could transport energy we could sell it.

I guess they'll figure out how to pack alot of power into small hydrogen fuel cells soon and then hopefully oil will be less used for energy and the cleaner solutions will be more viable.
