Climate ProgressÂ
Quick question. Â Your
state has good sunshine, lots of open rooftops, and the cost of
solar energy has been falling by 10% per year. Â Do you think it will take 13 years to double the 10 megawatts (MW) of installed solar power?
Â
Yes, if you’re the largest corporate
utility in my state, and willfully ignoring the economic trend.  But “˜no’ if you make decisions based on data, because the price of unsubsidized solar electricity will undercut most utility retail electricity prices within a decade, enabling 200 times more solar (4,400 MW) than found in this utility’s plans.
Â
That’s just one utility’s wake up call in a new report from the Institute for Local Self-Reliance (ILSR), Commercial Rooftop Revolution, and it’s far from the only one. Â By 2016, over 100,000 MW of unsubsidized rooftop solar will able to match grid electricity on price. Â Within 10 years, it will be 300,000 MW, enough to provide 10% of the nation’s electricity. Â This affordable solar future presents a stark challenge to traditional utility planning and a clarion call for better electricity policy.
