solar panels are so innefficient now, it just doesn't make sense. I have read that at todays effienciency, it would take nearly 20 years to payoff the initial investment of adding the panels. IIRC, the effiencieny of solar panels is around 2-5%, which is abysmal. One day, yes. Today, it is just too cost prohibitive (even with the government helping),

Low efficency doesn't matter if you got infinite amounts of the energy source. The payoff time depends heavily on the amount of sunlight you get and this is why it is retarded to have any kind of goverment incentive in the UK or Germany.California makes more sense especially when you consider the saved transmission losses.

Largescale solar powerplants work more efficent with the heat of the sun. Spain has some running that even can store excess energy. Those can be good solutions to to supply SOME of the energy demand in the right regions.

We didn't go from biplanes to supersonic jets overnight.

EV's are not a practical or cost effective solution at the moment,there's a lot left to be done before that's viable.

You didn't get to the moon with that attidute either.
