LA's next source of energy: a massive solar panel and lithium battery array in the Mojave, operated by 8minute Solar Energy, and capable of supplying 6-7% of the city's energy budget, with four hours of nighttime use. It will cost an eye-poppingly low $0.03.3/kWh, cheaper than natural gas. Read the rest
A new report from the International Institute for Sustainable Development (IISD) estimates the cost of subsidizing a full transition to clean energy, and comes out with a figure that is only 10-30% of the subsidy presently given to the planet-destroying fossil fuel industries. Read the rest
In Numerical investigation of the convection heat transfer driven by airflows in underground tunnels (Sci-Hub mirror), a group of engineers from L'Ecole Polytechnique Fédérale de Lausanne and the Swiss Federal Institute of Technology propose that low-cost heat-exchangers placed in subway tunnels could be used to heat and cool homes essentially for free (the system would last 50-100 years, and the pumps would need replacing every 25 years).

New York City's just-passed Climate Mobilization Act rolls up six climate-mitigation laws that comprehensively remake the city's approach to climate change (it's colloquially known as the Green New York Deal). Read the rest
It's not just Amazon and Apple that expect massive taxpayer subsidies in exchange for locating physical plant in your town: when Google builds a new data-center, it does so on condition of multimillion-dollar "incentives" from local governments -- but Google also demands extraordinary secrecy from local officials regarding these deals, secrecy so complete that city attorneys have instructed town councillors to refuse to answer questions about it during public meetings.

The unrepeatability of the Fleischmann–Pons experiment in the 1980s soured the world on cold fusion as a possible energy source for decades, but recent fusion reactor breakthroughs seem to indicate that the world will soon have an abundant supply of cheap, clean energy. Read the rest
Trump's about to make a bunch of whales, turtles, and dolphins go deaf.
The Trump administration is about to take a preliminary step toward oil and natural gas drilling off the Atlantic shore, by approving requests from energy companies to conduct “deafening seismic tests that could harm tens of thousands of dolphins, whales and other marine animals,” reports the Los Angeles Times.

“This is a pivotal moment for California, for the country, and the world.”
On Tuesday, California state lawmakers passed SB100, a major bill that would commit to making the state’s electricity supply completely emissions-free by the year 2045. SB100 passed 43-32. Read the rest
Even what's billed as the world's largest lemon battery can only generate enough juice to charge a small battery cell, so Mark Rober tries a few other fun power generators with a bunch of young scientists-to-be. Read the rest
Improved super-thin solar panels and nuclear fission are all in development to handle the massive logistical problems of meeting power needs in space. Fraser Cain takes viewers through the newest developments, including NASA's new Kilopower Reactor. Read the rest
Yesterday, I saw a demo of the Homebiogas bioreactor: it's essentially an artificial stomach that uses colonies of microbes to digest your home food waste (it can do poop, too, but people tend to be squeamish about this), providing enough clean-burning biogas to cook your next meal, heat your house, or run a generator -- what's left behind is excellent fertilizer.

After Digiconomist's analysis of the total energy consumption of the Bitcoin transactions on the blockchain went viral, Timothy Lee at Ars Technica provides a much-needed reality check in the form of some technical detail and nuance about what that energy consumption means, and where it might go.

Nuclear energy produces less carbon dioxide than any other any source (including solar, wind, and geothermal). But nuclear waste is extremely poisonous, and leaks are inevitable. Wendover productions looks at the problems surrounding what to do with the byproducts of nuclear power plants. Read the rest
When the wind is blowing, the great plains could generate enough power to supply all of America, but storing and moving energy to supply those places where the wind isn't blowing, the sun isn't shining and the tide isn't coming in is a significant technological challenge that we're still figuring out.

A brand manager at Dong Energy finally convinced them that their company name might be getting in the way of their messaging. They will be Ørsted from here out. Read the rest
Skycool Systems is a Stanford spin-out that uses panels composed of "layers of silicon dioxide and hafnium oxide on top of a thin layer of silver" to convert the waste-heat from air-conditioners' heat exchangers into 8-13 micrometer radiation, which passes through the atmosphere and radiates into space.

The oil industry is mired in a recruiting crisis because its workforce is aging out and millennials don't want to work for an industry that is destroying the planet they were hoping to live on. Read the rest
