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
And, an aside on PV,
There’s a discussion way off at Energy Institute at Haas about how unfair solar owners are, under current government policies, to electrical customers who do not have PV accessible. It’s irrelevant. Fossil fuels are done, stranded, the walking dead. Boss … Continue reading
The story’s at Bloomberg.
(Click on image to see a larger figure, and use browser Back Button to return to blog.) Our system, and its supporting cast. This is about energy democracy, as much as it is about other things.
“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
Not a recommendation, but a sketch of what’s possible. And it’s also a sketch of how much The Commons provides.
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.
And that does not include any governmental incentive payments from utilities. These were:
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

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

It’s heading towards year’s end, so it’s natural to think about perspective. In a post from last July, Joseph Heath asks semi-rhetorically, “Why are [proposed] carbon taxes so low?” and, then, he and commenters go on and answer that, essentially, … Continue reading
Just about a year ago, our home in Westwood began a march towards zero Carbon consumption, with heating, hot water heating, and even lawn mowing all converted to high efficiency electricity. As indicated at the time, our main automobile, a … Continue reading
