Pragmatically speaking:
Nuclear and wind power will likely never reach the public support necessary to eclipse the use of fossil fuels. Nuclear power because of the perceived harm, and wind power because "ohh those windmills are ugly and I don't want to see them".
That leaves solar+hydro. Since pure hydrogen does not occur naturally, that means it must be manufactured somehow, so you're basically reduced to solar power (unless you use fossil fuels to generate the hydrogen, which sort of defeats the purpose here). I don't think our solar extraction technology is quite efficient enough to cover all of our fuel needs, or we'd already be doing it.
