In October of 2013, Karl Ragabo was interviewed on the Talk Solar podcast from Beth Bond of Decatur, GA. This was shortly after the first version of the Value of Solar report was issued by IREC. Listen to it below: … Continue reading
“Renewables are set to penetrate the global energy system more quickly than any fuel in history” (BP, 2019 Energy Outlook)
Selections from BP Energy Outlook: 2019 edition: In the ET scenario, the costs of wind and solar power continue to decline significantly, broadly in line with their past learning curves. To give a sense of the importance of technology gains … Continue reading
From PV Magazine‘s John Weaver: At Solar Power Northeast, the DOER of Massachusetts noted that with the mandated 400 MW of qualified projects program review upcoming, and heavy volume deployed in National Grid territory, there is strong consideration to expand … Continue reading
This is utility-scale capacity only. See the footnote from the original post repeated at the bottom. Also, given uncertainties related to federal data availability at federal Web sites during the partial federal shutdown, I have copied the cited report and … Continue reading
(Slightly amended with code and data link, 12th January 2019.) Prediction of electrical load demand or, in other words, electrical energy consumption is important for the proper operation of electrical grids, at all scales. RTOs and ISOs forecast demand based … Continue reading
Update, 2018-12-15 (Click on image to see larger figure, and use your browser Back Button to return to reading blog.) Thanksgiving in 2018 was cold, but it was also sunny. That means the 150,000 solar installations in Massachusetts could delivery … Continue reading

What will happen to fossil fuel-fired electric bills everywhere, eventually, including those fired by natural gas
See Cost of Coal: Electric Bills Skyrocket in Appalachia as Region’s Economy Collapses, by James Bruggers at Inside Climate News. Excerpt: The common denominator is American Electric Power, one of the nation’s largest utilities. It owns Kentucky Power, along with … Continue reading
As John Farrell says, Keep your energy local. If you want to take back control of your democracy, a priority is taking back control of your energy supply. Centralized energy centralizes political power and influence. Listen to more from a … Continue reading
I love it. Professor Tony Seba, Stanford, 1 week ago. It means anyone who continues to invest in or support the fossil fuels hegemony will be fundamentally disappointed by the markets. And it serves them right. By efficiency, or momentum, … Continue reading
The headline and a page with lots of graphics and associated worksheets come from this PV Magazine article. The underpinning assessment is from GTM Research and their report Trends in Solar Technology and System Prices. Recall that Natural Gas Combined … Continue reading
AS Arman Oganisian of Stable Markets writes “There are no solutions, only trade-offs.” That is a fundamentally engineering attitude. It is fundamentally about the economics, and, in particular, the dramatic drop in levelized cost of energy for wind and renewables, … Continue reading
(reblog) Bill Ritter, Jr, Colorado State University: “Market forces are driving a clean energy revolution in the U.S.”
Transforming U.S. energy systems away from coal and toward clean renewable energy was once a vision touted mainly by environmentalists. Now it is shared by market purists. Today, renewable energy resources like wind and solar power are so affordable that … Continue reading
There’s a discussion way off at Energy Institute at Haas about how unfair solar owners are, under current government policies, to electrical customers who do not have PV accessible. It’s irrelevant. Fossil fuels are done, stranded, the walking dead. Boss … Continue reading
The story’s at Bloomberg.
“No zoning ordinance or by-law shall prohibit or unreasonably regulate the installation of solar energy systems or the building of structures that facilitate the collection of solar energy, except where necessary to protect the public health, safety or welfare.” That’s … Continue reading
Update, 2018-01-16 Vox has a widely acclaimed update to this story. (rubbing hands gleefully) Utility scale bids at Xcel Energy had median prices of 2.1 ¢/kWh for wind-with-storage, and 3.6 ¢/kWh for solar-with-storage. Hat tip to Utility Dive. In U.S. … Continue reading
Excerpts from statements by Richard Glick, FERC commissioner are given below. The Microgrid Knowledge (“MGK”) news article summarizes the context by writing: The commission rejected the energy secretary’s assertion that retirement of coal and nuclear plants threatens electric resilience. Instead … Continue reading
Updated, 11th January 2018 There’s been a lot written about natural gas, New England, and supposed price spikes due to constraints on pipeline capacity. I’ve had my turn a couple of times here (and here), as a matter of fact … Continue reading
Not a recommendation, but a sketch of what’s possible. And it’s also a sketch of how much The Commons provides.
Love your home. The H-field is measured in amperes per metre (A/m) in SI units, and in oersteds (Oe) in cgs units. From Wikipedia. Ørsted.
(Slightly updated 2nd October 2017 to add a link to the Brattle Group’s report on the myth of baseload generation.) Secretary of Energy Rick Perry has recently called for `baseload` coal and nuclear plants which are no longer competitive in … Continue reading

Wonder why other towns aren’t that smart?
You want to sell that house, right? You want to buy a house? Why oughtn’t the recurring costs of operating a home be a factor? Especially it’s energy costs. U.S. homeowners spend an average of over $2000 a year on … Continue reading
HOW ON-SITE ENERGY SOLUTIONS CAN HELP SAVE THE GRID RE:THINK ORIGINAL SIEMENS The traditional power grid is under tremendous pressure. In many places, infrastructure needs to be upgraded. Extreme weather and cybersecurity are constant concerns. These challenges threaten entire communities … Continue reading
Google: “Renewable energy is boosting economies”.
Kevin Sullivan decided to access the second stream of income from a large solar PV array on his farmland property to help him keep the property profitable. This is popular enough that it’s gotten a name: dual-use. Having just returned … Continue reading
