Nuclear is a good source to use till we have viable alternative sources.
Solar panels are just getting to the point where they can actually generate electricity at decent level. This will be our most valuable alternative source.
Wind and water power is ok at best but viable only for small towns near the waterways so this is a no go.
Nuclear Fusion cannot happen due to the fact the universe always needs a transfer of energy from one state to another. You cannot create an unlimited power source without having some ultimate ramifications affecting some critical component in our Universe.
That energy source used in the movie Iron Man. That is possible... maybe. Just in battery tech?
The solar tech in Gundam 00. That would be interesting to see if it can be done.
