Solar panels convert sunlight into DC electricity. Having DC we can easily electrolyze water and produce hydrogen. The whole technology of hydrogen economy exists: gas tankers can carry hydrogen over the oceans, heating can be done with it, from FIAT I can buy even a car. When will we escampe from reasons to wage war for oil?

Did you know that the making of solar cells is energy intensive? What does that mean? Simply this, it takes as much energy to make a solar cell as it is likely to produce over a life span of about 50 years. This is why everyone does not use solar cells to power everything. When solar cells can be made without consuming as much energy as they produce, solar cells will solve the energy crises. Until then, they are only marginally useful. Electrolyze water and use the resulting hydrogen? Are you serious? Are you aware that there is only so much water on the planet earth? How long do you think the water on earth would last if we were consuming/destroying it for our major energy needs? We could live without oil, but not water. Currently, we do not destroy water when we consume it. We recycle it. You know, the weather, rain, that sort of thing, eventually purifies and recycles virtually all water. So, sure let's continue research into how to electrolyze water, but let's also do some research on how to put the H2 and the O back together again. Hint: The major greenhouse gas you always hear enviromentalists complaining about is water. Where does the infamous greenhouse gas come from? So, to answer your question," When will we escape from the reasons to wage war for oil?", NOT ANYTIME SOON!

(1) Hm .... are you sure, you still are right that modern solar cells need more energy to be produced, than they will cash back during their lifetime? Meanwhile we have amorph cells and thin layer cells which have less silicon per installed kW(peak). (2) The water resources shouldn´t be the limiting factor. Any electrolyzed quantitiy is recycled to the sea on the path which you described. (3) Water as a greenhouse gas? Is the most lovable one, since nature can freeze it out. Carbon dioxide and methane don´t give this option.
