The class “Climate Science for Climate Activists” I have taught for the last 6 or so weeks is now completed. The slides are available here.
More details. And, from that Lefty Socialist rag, Forbes.
(To see a larger figure, click on image to open it in a new browser window. This is from ILSR‘s “Of New Power Generation, How Much is on the Roof? Quarterly Update — 2019 Q1“.) It was once warned, and … Continue reading
This is from an article in Science by Haegel, et al which just was released today. It means, documented in detail, that the projections of Professor Tony Seba are not only right on, but Professor Seba may have underestimated the … Continue reading
There is a climate emergency. There are many ways of looking at this, from the big investments perspective (see also a Fed view), to human harms perspective (see also), to what it might cost to reverse these changes if they … Continue reading
October 2013 retrospective … Karl Ragabo on ‘Talk Solar’ podcast, regarding value of solar generation
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
And this is ISO-NE, who, as little as three years back were highly sceptical anything other than additional natural gas generation could supply the ever increasing electrical power needs of the region, particularly with the withdrawal of generation from oil, … Continue reading
From end of 2018: from alianza FiiDEMAC. And, indeed, it was one of the most uplifting two hours I’ve recently spent. I have long been an admirer of Professor Tony Seba. I have read his books. This was an update … 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
I’ve been looking over the set of bills proposed for the current Massachusetts legislative session. There are more of them, all dealing with aspects of greening energy supply and transport. And Governor Baker’s S.10 is very welcome. (By the way, … 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
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
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
LLNL Sankey diagram of U.S. national energy flows in 2017: What’s possible, what’s not, and who’s responsible
(Updated, 2018-05-02. See below.) I love Sankey diagrams, and have written about them with respect to influence of Big Oil on U.S. climate policy, and in connection with what it takes to power a light bulb, providing a Sankey-based explanation … 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
And, an aside on PV,
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
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.

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.
