Ted Rall’s “Left, Center and Right: We’re All in Denial About Climate Change”
(Friend, fellow congregant, and committee chair Will Rico of First Parish in Needham sent me this highly appropriate link.) Ted Rall argues at Counterpunch that: Those who deny that climate change is real are engaging in what psychologists call “simple … Continue reading
50 Terawatts of Solar Photovoltaics (“PV”) is now feasible by 2050
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
So, y’say you want a Green New Deal …
There isn’t a lot known about the Green New Deal or “GND”. Its proponents are certainly making the rounds, but it is light on specifics, heavy on urgency, heavily coupled with advancing jobs and justice, racial, climate, and environmental. As … Continue reading
October 2013 retrospective … Karl Ragabo on ‘Talk Solar’ podcast, regarding value of solar generation

Welcome to snowy New England … Bad place for solar PV, right?
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

Love means nothing, without understanding, and action
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 path to US$0.015/kWh solar power, and lower” (PV Magazine and GTM Research)
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
What gives me hope … And it ain’t the small stuff
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
storage
And, an aside on PV,
wind+storage 2.1 ¢/kWh, solar+storage 3.6 ¢/kWh
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
FERC: No multi-billion dollar bailout for coal and nuclear generating facilities
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
reality of natural gas prices: volatile, undependable, and contrary to social interest
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
How hard can completely off grid living be?
Not a recommendation, but a sketch of what’s possible. And it’s also a sketch of how much The Commons provides.
What does it really mean for an electrical grid to be resilient?
(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

On Hoarding Electrons
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
