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.

A new report released today by the Institute for Energy and Environmental Research shows that Minnesota can meet 100% of its electricity needs with in-state wind and solar power, and (with ample energy efficiency investments) at a comparable cost to its existing electricity supply. The notion that solar and wind energy cannot be the mainstay… Continue reading
Update 3/27/12: added clarification to text and chart that prices include federal tax incentives If the cost of electricity were the only factor in energy discussions, we’d probably have a lot more coal and a lot less renewable energy. But the truth is that renewable energy can compete on cost and distributed renewable energy has… Continue reading
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
I just came across an interesting interview that radio host Diane Rehm did with Jeremy Rifkin, author of The Third Industrial Revolution. The excerpts below lay out his vision for an energy future that is decentralized and democratized. (He also notes that this vision has just emerged in the past two to four years, but we’ve been around since 1974…).
The book is organized around five pillars of the third industrial revolution:
Pillar one, renewable energy. Pillar two, your buildings become your own power plants. Pillar three, you have to store it with hydrogen. And then Pillar four…the internet communication revolution completely merges with new distributing energies to create a nervous system…Pillar five is electric plug-in transport…
when distributed Internet communication starts to organize distributed energies, we have a very powerful third industrial revolution that could change everything…
You can find some renewable energy in every square inch of the world. So how do we collect them? … If renewable energies are found in every square inch of the world in some frequency or proportion, why would we only collect them in a few central points? …
[it] jump starts the European economy, that’s the idea. Millions and millions and millions of jobs. Thousands of small and medium-sized enterprises have to convert 190 million buildings to power plants over the next 40 years…
That’s the vision: a decentralized energy system can be democratized with local ownership, spreading the production of energy and the economic benefits as widely as the renewable energy resource itself.
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
