Distributed Solar: The Democratizaton of Energy

“…. [T]here’s something wonderful about … shooting for 200% renewable generation [over what’s needed] rather than struggling to get to 90% or net zero”
Professor Saul Griffith, MIT I think our failure on fixing climate change is just a rhetorical failure of imagination. We haven’t been able to convince ourselves that it’s going to be great. It’s going to be great.
Consumer, Employment, and Environmental Benefits of Electricity Transmission Expansion in the Eastern United States
If local towns and neighborhoods continue to oppose decentralized zero Carbon energy, whether solar ground mounts or utility scale solar farms or wind turbines, we’re going to need more transmission, much more transmission. Opponents to decentralized solar generation are either … Continue reading
Sunday’s Boston Globe had a lead article about the demise of opposition to the Weymouth natural gas compressor station, defeated by Commonwealth and federal support for its operation. Many people I know protested that scourge of Weymouth and the Commonwealth, … Continue reading
Where does a state government turn when they have a strong mandate to remove fossil fuels from electricity generation, heating, cooling, and transportation? Suppose they proposed a cross-border hydropower purchase from Quebec? Suppose they planned to roll out land-based wind, … Continue reading
This is a retake of a presentation at the invitation of the Walpole Greens and made at their meeting of 9th November 2020. It is longer and more leisurely. I interleave some of the answers to questions that followed the … Continue reading
Ilana Cohen of the Pulitzer prize-winning Inside Climate News reports how some environmental activists in northern New England are concerned about the progress of tapping Canadian hydropower to feed the electrical needs of New England. Opposition is also voiced by … Continue reading
That’s Sundar Pichai, CEO, Google and Alphabet. Ørsted : “Love your home”
From Inside Climate News and I’m sure it’ll eventually show up at Legal Planet, where they touched the matter over a year ago: The new rules, approved by the Federal Energy Regulatory Commission, are designed to counteract state subsidies that … Continue reading

Suggested citation: Davis, Lucas. “Electrification? We Are Already On The Way“, Berkeley Haas Energy Institute Blog. Even without environmental incentives, the United States has moved towards greater electrification. Note, however, that Massachusetts is not numbered amongst the Enlightened.
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.
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
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
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
Featured in Science Magazine today, NuScale Power, a spinout from Oregon State University, is planning simpler, smaller, safer gang-lashable nuclear reactors, with a trial in the early 2020s. A schematic is shown below. As I’ve noted here elsewhere, the reason … 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
I just listened to the podcast from Peter Gibbs of BBC Radio 4‘s program, “Costing the Earth”. He recounts the experience of owning and driving a nominally 200 mile range EV: Is the time finally right to buy an electric … 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
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
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
(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.
“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
