(Click on image to see generation right now.) That’s 53.9 kWh, and a peak generation of 8.1 kW. And it’s just after Spring Equinox. Postscript. Utility-DIVE reports that ISO-NE now estimates installed solar in New England by 2025 will be 30% … Continue reading
Hey, Mr Eversource, Mr National Grid, Mr Associated Industries of Massachusetts, still think you have an energy future? Meet the Green Tea Coalition. It’s about the right to be self-sufficient, and self-sustainable. It’s about big government and big corporations and … Continue reading
Officially, today, 29th at 1600 EDT, our home was free of using fossil fuel energy. We now have: A 10 kW nameplate SunPower/RevoluSun solar array on our roof, which generated 49 kWh today, and gives remarkable, over-the-top performance despite there … Continue reading
(Click on image to see full size. Use browser Back button to return to blog.) And it’s not even a storm. Think of all the energy in those winds!
Postscript, 2nd April 2016 I’ve been asked offline whether I buy McPherson’s catastrophic warming scenario. I don’t, or at least I wouldn’t bet on it. Each of the components of Professor McPherson’s scenario are based upon solid science. But in … Continue reading
“This solar future is inevitable — the key question is how long it will take” (David Roberts, of VOX)
Here it is: solar photovoltaic (PV) power is eventually going to dominate global energy. The question is not if, but when. Maybe it will happen radically faster than anyone expects — say, by 2050. Or maybe it won’t be until … Continue reading
Update: 20th June 2016 “Rising seas: Should I say or should I go?“, by Delavane Diaz WunderBlog.
Highly recommended. Always moving, at least for me. Engineering is a serious business: http://mit.tv/AjqL6n Engineers and their programs are embedded in organizational structures. These structures control the success or failures of the program. In dealing with high risk technologies the … Continue reading
Hat tip to Climate Denial Crock of the Week. See his Web site. Paraphrasing, what enabled Germany to have its Energiewende Scheer said that what happened in Germany it was necessary to open the space for the people to act. … Continue reading
Happy Vernal Equinox! This post has been updated today with some of the equations which correspond to the models. An assessment of whether or not there was a meaningful slowdown or “hiatus” in global warming, was recently discussed by Tamino … Continue reading
News on the diddling-with-metering front. I argued in a comment today that the standard rationale for a change in net metering is based upon accounting and legal contract which is both unsound physics and unsound mathematics. Recall that that rationale … Continue reading
That’s 16 Gigawatts, folks! See CleanTechnica for more.
The American Statistical Association of which I am a longtime member issued an important statement today which will hopefully move statistical practice in engineering and especially in the sciences away from the misleading practice of using p-values and hypothesis tests. … Continue reading
Where we’ll go should net metering be nixed.
(Click on picture to see a larger image, and use your browser Back button to return to reading.) Getting steady data from the Earth’s oceans demands commitment and not a little courage. I could never do what these oceanographers do, … Continue reading
