    Right and so...how do you intend to power the creation of hydrogen?

    Uh... the same way you intend to fund the triangulation of bananas.

    Was this a trick question?

    No, do you know of the energy required to make hydrogen...and the amount thats needed to supply a single city, let alone an entire country?

    I dunno. People and animals tend to shit a lot. I kind of think we'll have plenty.

    Pardon me, but who on earth said anything about 'creating' hydrogen?

    I posted in some detail about coal and biomass gasification. That appears to me to be the obvious next step. The step after that depends on next-generation nuclear power plants, which are already in the works.

    I have no idea why you think that hydrogen is indispensible to our energy future, but I will remind you of the definitition of fuel: It's a chemical storage medium for energy to be released by combustion. The energy you get out of it is equal to the energy you put into it, minus entropic losses. So, if you decide to generate hydrogen by electrolyzing water, say for example, it does take a lot of energy... but the energy you get out of the hydrogen when you burn it is exactly equal to the energy that was required to electrolyze it in the first place.

    You see, to break water down into its components, you have to add enough energy to the water to break down the bonds between the hydrogen and oxygen atoms. When the hydrogen is burned to release energy, it is reacted with oxygen (which is what combustion is, an oxidation reaction) and the result is energy (the amount you put into it) and water (which is what you started with).

    Think of hydrogen as a big clockspring. You wind it up with electricity, and it can unwind to power your car, or house, or what have you.

    The same is true of every other fuel, including coal, petroleum, natural gas, biodiesel, firewood, and so on, but that fact tends to get obscured by the fact that the energy thus stored is primarily solar, and we tend not to think of fuels as a storage medium for solar energy. It's an error, because that's exactly what they are.

    If we need to include elemental hydrogen in our energy future, the power will come from nuclear plants.

    I suppose if I woke up one day and all the oil was simply gone as if taken away by magic, society would implode. Too many processes depend on it.

    But that will not happen. Rather, cheap oil will become increasingly scare and thus expensive. Alternatives will be utilized. That these alternatives exist is not in question, nor their eventual utilization, the question will be their relative cost. Will it be cheap energy or expensive energy?

    Regarding hydrogen, it will be less efficient to use hydrogen than to use electricity, so I think it will depend how well battery technology comes around by then.

    What would you do, if in 2 years, all oil was used up?
    Hook the car up to my gut...

    That should be able to run it for a while

    My husband and I would be ruined financially, for one, considering I work in the O&G industry and he own a trucking company.

    The fact is, without diesel, society would stop functioning as a whole, even if we all bought bicycles and read by candlelight. So, I would probably attempt to grow my own food, buy a few guns and some ammo, and not leave the house until someone else solved the problem. I can't imagine the chaos that would go on...

    Because what you say is true, there would be diesel or a reasonable facsimile thereof. We have the raw materials, the technology, and the manpower to make it happen; it's just not economical to do so under the present market conditions.

    Americans consume petroleum products at a rate of three-and-a-half gallons of oil and more than
    250 cubic feet of natural gas per day each! But, as shown here petroleum is not just used for fuel.
    Its not just about energy.
