I think a big problem is just people consume resources in stupid ways.
Take for instance a lot of people's houses when I head over. Several TVs on when no one is watching them. Lights on in every room when it's a sunny day and you're not getting any extra lighting.
It's one thing if this was one or two people, but when just about every household you visit throughout the country is like this...
I'm not talking about "work in the dark, it'll save trees" I'm talking about simple, common sense things like turning off your damn TV when you're not watching it.
Anyway, if people were smarter with power consumption, solar and wind would be viable electricity choices.
Hydrogen fuel cars are also a good idea, that is if the cracking stations are using solar or wind.
Of course, the ideal would be to convert the solar system into a dyson sphere
