>>>Depends how you produce it. The way GW(2)B's administration wants to do it, it seems to be using, guess what, oil. On Iceland, they use thermal energy to produce electricity, and then use that to electrolyse water, with oxygen as a byproduct.

>Seems to me that's actually an important point. We're not going to solve the fossil fuel problem until we stop looking for a single solution and go after a variety of solutions that work in different situations and locales. The answer for heating homes is probably different than the answer for fueling cars, which may be different than the answer for providing light. And, as you pointed out, the answer for Iceland may be different than the answer for Spain, which may be different than the answer for Canada.

And all we've got in the UK is coal (and most the mine's are closed now). In Canada maybe they can heat homes by harnessing the flapping of arms to keep warm by the people up north :-)
