what post did TJ go into explaining why alternative energy sources don't work because technology isn't there yet?

Don’t know post but the tech is here with Enphase Solar products. I just got my Enphase AC battery backup system which is grid tied but if grid goes down I keep going with everything I have. It is expensive though, but $25 a month electric bills are easy compared to $200 a month bills.$25 is a minimum bill to be tied to grid, but I could dump them, then $0.
