Few energy facts matter more than the competitive posture of solar. Solar that is competitive with the grid is an energy game changer like shale gas.
Solar today is competitive in 16% of US electric service territories and will be competitive in 33% by 2017. Who says that? Not a solar trade group. But the Edison Electric Institute, the association of public utilities.
At page 3 of the linked to report, EEI says solar right now is competitive with grid power in the 16% of electric service territories where the price is 15 cents per kilowatt-hour. Moreover the number of service territories where solar is becoming competitive rises each year, jumping to 33% in just 5 years or by 2017.
The solar revolution is underway and accelerating.
