  •  Solar *power* is cheap. (1+ / 0-)

    Solar power storage is expensive.  To get a lot of people to abandon the grid will take some major improvement in the cost of household-scale storage.  I could see it in India, where the grid commonly cuts off for hours each day and anyone who can afford it has a generator.  There, solar panels and several tons of batteries could compete on price versus a generator.  In the US where power failures are rare, no, I don't see a lot of people that are now grid-connected cutting themselves off.  

    What I do expect is that people will install rooftop solar, produce more power than they use during the day, and sell the excess to the electric company.  Then at night they will buy power.  Power companies' spikes in demand will be lower and will shift from summer early afternoon to winter evening and summer overnight.  

    Of course, if some new breakghrough makes energy storage cheap, I'd expect lots of people to cut off from the grid.  

    Renewable energy brings national global security.
