I'm sorry, not to be too much of a dick but you're just typing out your opinions without bothering to check if they have any basis in reality. I'm not going to spend my time tracking down sources if you're not.

Intermittent power sources could be good enough if people were willing to accept intermittency i.e. get used to not having air conditioning at night, get used to only cooking when the Sun is up, get used to nightshifts no longer being possible, etc. It's not fun, but it's doable.
