In a recent interview, Professor Tony Seba of Stanford University predicted that solar+storage was going to achieve parity with average grid transmission costs by 2022. This is what he called “god parity”, because even if utilities generated at zero cents … Continue reading
Certain claims regarding contributions of health programs to the United States federal budget in a debate last night made me curious, and so I checked the figures on this from the Office of Management and Budget. Of special importance to … Continue reading
Hat tip to And then there’s Physics …: On climate change and Astrobiology , by Adam Frank.
(Updated, 2016-07-14) See Shayle Kann’s great piece at GreenTech media. The choices: “Version one: Aimless transformation” “Version two: The balkanized grid” “Version three: Embracing the transformation” In addition to solar PV, wind energy of all forms (especially underutilized local wind … Continue reading
Some progressives lament the loss of Bernie Sanders’ run for President, arguing “we need to get our democracy back.” A necessary step in order to get your democracy back is to take back control of your energy supply. Centralized energy … Continue reading
See Feeding humanity in a warming world. Dr Suzuki links University of California, Berkeley, Professor Miguel Altieri’s “Principles and strategies for designing sustainable farming systems“.
This is a video and link from The Rocky Mountain Institute about New York State’s Reforming the Energy Visions or “REV”. I have written about REV before.
What New York State is doing, and Massachusetts, apparently not. Cheap supplies of domestic natural gas have driven the New England power plant market toward that fuel and away from the more expensive coal, oil and nuclear material. Limited capacity … Continue reading

Also note Oxfam’s “World’s richest 10% produce half of carbon emissions while poorest 3.5 billion account for just a tenth“. Update, 2016-04-28: And what, exactly, does the Paris agreement (COP21) mean? See this story.
I’ve written about Sankey diagrams before, and Professor Kevin Anderson appeals to them to promote demand reduction as a powerful pathway to reducing Carbon emissions. But the overheads associated with transmission and distribution affect large scale generation of solar and … Continue reading
Or is Governor Baker and the Massachusetts House going to subcontract that to other states, like Maine, Rhode Island, Vermont, and New York? They are coming. Update, 2016-02-23 Where does Massachusetts get its energy now?

“Wealthy nations spend 40 times as much money subsidizing fossil fuel production as they contribute to the Green Climate Fund”
The next time you hear or read some wag, random solar-hater, or shill for a dirty fossil fuel company (like “natural gas”, really, explosive methane), or the likes of Spectra Energy bemoan the subsidies states like Massachusetts and New York … Continue reading
