Some note on hydrogen:
Have you ever dug out some of it, ever seen it come out of a drilling hole? No, then this is probably because it has to be produced before it can be used. And the problem with production of hydrogen is that it needs at least the amount of energy that you later on can use by burning it. So hydrogen can act as a fuel, but not as an energy supply.
Some additional note on oil:
Ever wondered why all these sheiks invest in companies all over the world instead of their own oil-fields (of course, they also invest into their oil fields, but they pump billions of dollars into foreign countries)?
Maybe it\'s because they know that their fields won\'t be able to keep their actual production rate for more than maybe a decade or two?
Hell, maybe they can even continue producing for another half decade, but what then? By this time I\'ll be an old man (assumed I survive the next fifty years), and I don\'t want to freeze to death and see my (possible) children and grandchildren suffering because we now are too ignorant and selfish to stop driving around and start thinking about what we do.
To contribute something useful to this debate:
In germany the gas prices range somewhere from 1.30 up to 1.50 and more. (Gas and SuperPlus, for those who know those)
