“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
From PV Magazine‘s John Weaver: At Solar Power Northeast, the DOER of Massachusetts noted that with the mandated 400 MW of qualified projects program review upcoming, and heavy volume deployed in National Grid territory, there is strong consideration to expand … Continue reading
See the About section of this blog for a revision in the blog’s description and rules governing commenting made more explicit and prominent. In fact, I have copied these at the bottom of this post. The heading of the blog … 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
Gov Jerry Brown on Meet the Press, a parting comment on 2018 at Bill Gates’ Notes, and the best climate blog post of 2018
Segment One Outgoing Governor Jerry Brown of California on NBC’s Meet the Press this morning: I’ll miss him there, but I don’t think Gov Jerry is going anywhere soon. Segment Two Bill Gates Notes offered an end of year summary … Continue reading
Update, 2018-12-15 (Click on image to see larger figure, and use your browser Back Button to return to reading blog.) Thanksgiving in 2018 was cold, but it was also sunny. That means the 150,000 solar installations in Massachusetts could delivery … 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
As John Farrell says, Keep your energy local. If you want to take back control of your democracy, a priority is taking back control of your energy supply. Centralized energy centralizes political power and influence. Listen to more from a … Continue reading
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
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:
HOW ON-SITE ENERGY SOLUTIONS CAN HELP SAVE THE GRID RE:THINK ORIGINAL SIEMENS The traditional power grid is under tremendous pressure. In many places, infrastructure needs to be upgraded. Extreme weather and cybersecurity are constant concerns. These challenges threaten entire communities … Continue reading
