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

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

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

Wonder why other towns aren’t that smart?
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
Akamai (NASDAQ: AKAM) said it is making a 20-year investment in the planned Seymour Hills Wind Farm, which will be based outside of Dallas and is expected to begin operating next year. The project is being developed by Infinity Renewables, … Continue reading
Net energy consumption at Westwood Studios, after solar generation, with zero Carbon house, and, now, Chevy Volt
I don’t have time to offer much in the way of explanation or comments here, but here’s the status of consumption per day, in Kilowatt-hours. Update: I should have provided some context. (Click on image to see a larger figure, … Continue reading
