We're seeing a revolution where solar is disappearing into the building.

California clearly has been a U.S. leader.

Solar stocks as a group are probably up 4 to 6 times more than most of the commonly followed indices.

Shifts in energy happen over decades and not over years. Eventually renewable will be on such large scale that you see smaller growth rates. But we hope by then that clean energy become 35-30 percent of mix of energy used in this country.
