Fair enough.

From what I understand, those are not worth the cost. Is is even remotely feasible to even produce, let alone build, enough solar and/or wind electricity production plants which give enough hydrogen to be able to handle the world’s energy needs? Even in places with extended periods without sun and wind? Until that is true, nuclear seems to be the only alternative left which is not oil, coal, or natural gas.
(Left out is hydro, which, from what I understand, is already built everywhere it can be built.)
