Saw Al's comment on hydrogen, and sort of theoretically hydrogen is great except for one small problem. Hydrogen is so chemically active that there's very little free hydrogen just floating around, and freeing that hydrogen up from what it's bound to requires energy. More energy than the recovered hydrogen can produce to do work. Something about perpetual motion being impossible I think.
IF solar panels or some other method of utilizing solar energy can be developed that are inexpensive and efficient and won't need to cover vast areas of land that'd be great. Until then not so much.
One interesting thing that a lot of people who live in more or less perpetually cloudy areas like Western Washington State don't seem to understand is that while clouds reduce surface heating of the earth they also inhibit radiation of surface heat. Consequently when it's cold and cloudy in the winter, it's warmer than it would be if it were cold and clear.
