Within ten years, 100 million Americans in the nation’s largest cities will be able to get cheaper electricity from rooftop solar than their utility provides. That’s just the opening salvo from a new report from the Institute for Local Self-Reliance. “Rooftop Revolution: Changing Everything with Cost-Effective Solar,” not only illustrates the enormous, emerging potential for local solar power, but also describes how the rules of the electricity system must change now for the electricity system to be ready for the decade’s energy democracy opportunity.

This post was originally titled Residential Solar for $2.24 per Watt in Germany? The Germans are debating significant revisions to their landmark renewable energy policy, and instead of declaring the death of the German solar market, Americans should focus on why solar still costs so much on this side of the Atlantic. After a significant… Continue reading
The Germans have proposed significant revisions to their landmark renewable energy policy, the feed-in tariff, and the proposed prices should make Americans wonder why solar still costs so much on this side of the Atlantic. After a significant step-down in March, German utilities will be buying rooftop solar on long-term contracts from projects 10 kilowatts… Continue reading
What if installing more solar could reduce electricity prices? It’s already happening in Germany, world leader in solar power, and it’s likely to happen in the U.S., too. Continue reading
Updated 2/1/12 because I underestimated how the tiered pricing worked. Thanks to bkarney at Renewable Energy World for the comment. Last week I wrote about the time-of-use pricing scheme that PG&E offers in San Francisco, and how solar power is worth 14% more compared to a standard flat-rate electricity plan. In reality, it’s 36% or… Continue reading
In recent weeks, I wrote a Solar Grid Parity 101 and published an animated map of the year when major U.S. metro areas will reach solar grid parity. The most frequent criticism was “you didn’t include tax incentives!”
Yes, there is a 30% federal tax credit on the table until 2016 (barring Republican control of Congress and the White House) and it makes a substantial difference. Mouse over the following map to see the impact of the federal Investment Tax Credit on solar grid parity in 2016.
My one thought: if the ITC expires as scheduled, the 2017 map will have a lot more red than the 2016 one if we measure grid parity with incentives.
But you’ve seen the difference (from 3 states to 21 states with grid parity!), now vote in the comments:
Should the tax credit be included in a calculation of grid parity? Why or why not?
Note: This is a revision of the same post from last week, with an updated time-of-use pricing plan from Los Angeles. What if electricity cost more when the sun was shining? Many utilities are using new electronic “smart meters” to adjust the price of electricity as often as every 15 minutes, to reflect supply and… Continue reading
Solar grid parity is considered the tipping point for solar power, when installing solar power will cost less than buying electricity from the grid. It’s also a tipping point in the electricity system, when millions of Americans can choose energy production and self-reliance over dependence on their electric utility. But this simple concept conceals a… Continue reading
Update 1/12/12: I created a new post to reflect the current time-of-use pricing plan for Los Angeles Update 1/10/12: Fixed a missing pie chart and corrected a miscalculation caught by a reader What if electricity cost more when the sun was shining? Many utilities are using new electronic “smart meters” to adjust the price of… Continue reading
Yesterday New York Times reporter Matt Wald had a piece on the role of energy storage in supporting the expansion of renewable energy. However, his specific focus on solar thermal power generation overlooks the potentially high costs of relying on solar thermal power as well as the potential for distributed “storehousing” of renewable energy. Solar… Continue reading
