“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
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
(Updated 2019-01-12.) Despite the surge of interest in plastic bag bans, the environmental sustainability numbers haven’t been run. For example, it makes no sense to trade using paper bags instead of plastic ones, even if the paper is recycled, because … Continue reading
What the head of the American Petroleum Institute, Frank Ikard, said in 1965.
What will happen to fossil fuel-fired electric bills everywhere, eventually, including those fired by natural gas

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
Our additional 3.45 kW solar PV is up and generating today, collecting substantial numbers of photons (500 kWh) by 0800 ET. (Click on figure to see a larger image and use browser Back Button to return to blog.) (Click on … Continue reading
In addition to our 10.0 kW PV generation, we just added an additional 3.45 kW, via 10 additional SunPower X21-345 panels. The new panels are tied to a separate SolarEdge inverter, an SE3800H-US. (The older inverter is an SE10000A-US. The … Continue reading
This is a reblog from Eli Rabett, one of the post “On Records”, with additional comments and material from the author-moderator of this blog, 667-per-cm.net: A distinguishing mark of a new record in a time series is that it exceeds … 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
And, an aside on PV,
Done by the Virginia Institute of Marine Science, new sea-level report cards offer a look at current sea-level rise rates, and projections. What’s interesting to me is making the projections conditional upon the character of the model used to project. … Continue reading
The story’s at Bloomberg.
That’s Atlantic Avenue near the Aquarium. That’s Essex, in Cape Ann. That’s the Sargent’s Wharf parking lot. That’s is where General Electric wants to build their new headquarters (!). That’s Columbus Park, near the Aquarium. That’s Neponset Circle. That’s Plymouth … Continue reading

From David Suzuki, who I’ve cited here more and more often, from his blog post, Consumer society no longer serves our needs, of 11th January 2018. An excerpt: But where is the indication of our real status — Earthlings — … 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
tripleplus ungood: Long run hot climate models are also the most accurate reproducing today and recent past
Patrick Brown and Ken Caldeira dropped a bombshell into the recent (7 Dec 2017) issue of Nature, and the repercussions are echoing around the scientific world. (See, for example, the related article in MIT’s Technology Review.) To be crisp, current … 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.
(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
