With the cost of solar continuing to fall rapidly (50% in the past five years) and electricity prices rising steadily, if slowly, the approach of solar grid parity is near. The following chart illustrates the trajectory of solar cost and electricity price, hinting at the coming intersection. 1 The chart compares the cost of a… Continue reading

Solar cells are unusual in that they were cost-competitive from the get-go. From the Apollo space program to highway signs to lighting for buoys, solar could replace highly expensive power from batteries or other sources and eliminate the need for the construction of electric distribution lines.1 When the Institute for Local Self-Reliance was founded in… Continue reading
A presentation summarizing ILSR’s reports on the local solar opportunity as unsubsidized solar becomes competitive with retail electricity prices in nearly every state over the next decade.

Minneapolis, MN —Within a decade, more than 35 million buildings may be generating their own solar electricity (without subsidies) at prices lower than their utility offers, sufficient to power almost 10% of the country.
That’s the powerful headline from the Institute for Local Self-Reliance’s latest report, Commercial Rooftop Revolution. Despite the opportunity, utilities, regulators, and policy markers are largely unprepared for the surge of local solar power.

Although only 0.1% of electricity is generated by solar power in 2012; within a decade, 300,000 MW of unsubsidized solar power will be at parity with retail electricity prices in most of the United States and more than 35 million buildings may be generating their own solar electricity sufficient to power almost 10% of the country.

Last week the Minnesota Public Utility Commission had a rare live public comment period on Xcel Energy’s long term planning process (called an Integrated Resource Plan). At the urging of several fellow clean energy advocates, I gave my 3 minute testimony about the enormous gulf between Xcel’s 10-year plan for solar power and the solar… Continue reading
