Many people familiar with traditional energy networks, including the electrical grids of utilities, come with strong preconceptions to considering zero Carbon energy sources. This is particularly true of and for experts in traditional energy, including engineers. They focus upon the … Continue reading
I’ve been pretty hard on the Green New Deal. That’s partly because its proponents don’t seem to see that a transition to a new zero Carbon energy economy is inevitable. It’s opponents don’t see that either. It may not come … Continue reading
https://sms.cam.ac.uk/media/746045 Professor Bob Watson, University of East Anglia, presents the summary risk, climate change: The question is not whether the Earth’s climate will change in response to human activities, but when, where and by how much. Human activities are changing … 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
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

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
Can’t get enough of this video. It may be a corporate, Ørsted promotion, but it is beautiful. And I continue to believe, that, as the original sense of the corporation, or benefit society suggested, contrary to (U.S.) popular progressive belief, … 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
The story’s at Bloomberg.
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
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.
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”.
(The above video is intended to start at time second 2051 or at 34 minutes. WordPress is sometimes funny about that. Apologies if not.)
I was once scolded by an energy wonk and political progressive at a semi-public forum for suggesting people “hoard electrons”. That is, instead of being grid connected, there seemed to me to be situations where becoming as independent of the … Continue reading
