Electric vehicles – It's not just about the car - "One of the key characteristics of complex systems, such as the world's energy and transport sectors, is that when they change it tends not to be a linear process. They flip from one state to another in a way strongly analogous to a phase change in material science... A second important characteristic of this type of economic phase change is that when one major sector flips, the results rip through the whole economy and can have impacts on the societal scale."

The case for optimism on climate change - "I'll finish with this story. When I was 13 years old, I heard that proposal by President Kennedy to land a person on the Moon and bring him back safely in 10 years. And I heard adults of that day and time say, 'That's reckless, expensive, may well fail.' But eight years and two months later, in the moment that Neil Armstrong set foot on the Moon, there was great cheer that went up in NASA's mission control in Houston. Here's a little-known fact about that: the average age of the systems engineers, the controllers in the room that day, was 26, which means, among other things, their age, when they heard that challenge, was 18."

Tesla Powerwall Battery Economics: Almost There - "Elon Musk announced Tesla's home / business battery today. [video] tl;dr: It'll get enthusiastic early adopters to buy. The economics are almost there to make it cost effective for a wide market... That said, for large scale grid deployment (outside of the home), it still looks like flow batteries and advanced compressed air are likely to be far cheaper in the long run." [more inside]

The Economic Risks of Climate Change in the United States (PDF); prospectus (PDF); press coverage (YT) - "The signature effects of human-induced climate change—rising seas, increased damage from storm surge, more frequent bouts of extreme heat—all have specific, measurable impacts on our nation's current assets and ongoing economic activity. [The report] uses a standard risk-assessment approach to determine the range of potential consequences for each region of the U.S.—as well as for selected sectors of the economy—if we continue on our current path..."

FYI, we came close to losing the power grid back in 2012. What we? Oh, just the planet.
"While DC continues to race through San Francisco power lines at nearly the speed of light, it does so anonymously. You’ll find no reference to DC power distribution in PG&E’s annual reports or on its websites. Even some utility engineers are unaware of its existence, which raises a curious question: Why is the inheritor of this legacy, the mighty and sophisticated PG&E, still bothering with DC distribution 133 years later?"

Let’s say you’re a writer, working a novel set in Minneapolis. Your protagonist arrives home after a long day of doing whatever it is your protagonist does all day. To this point, you’ve been very specific with local landmarks and a general feeling of the city — your protagonist rides the 21A, eats breakfast at the Grand Cafe, and meets his or her attorney in an office on the 12th floor of the Rand Tower. All good so far. You’ve set the scene very effectively. People are going to say, “This is a great Minneapolis novel" after they read it. However, the time has now come for you to insert a specific street address into the text. You like specifics, and you need a real-sounding mailing address for, say, a situation where the protagonist receives a mysterious letter. How will you accomplish this? Here you have a problem. You only have two options, neither one very good. [more inside]

Audio recordings usually include a low-level background noise caused by electrical equipment. The hum contains small frequency fluctuations which are propagated consistently over entire power grids. By storing the pattern of grid-wide fluctuations in a database forensics experts are able to use the hum as a watermark. This can determine when the recording was made, where it was made and whether it was recorded in a single edit. [more inside]

According to an article posted in today's Wall Street Journal, the electricity grid in the U.S. has been compromised by foreign spies, leaving it vulnerable to disruption. Last year, the CIA acknowledged that the system had been compromised and that the goal had been extortion. In response, the Federal Electric Regulatory Commission issued new cybersecurity specs for the power grid, to which companies such as GE have begun responding. But could it be that the new security efforts are motivated by government officials who stand to gain by this attempt at drastically increasing government control over the Internet? [more inside]

The Dervaes Institute is an 'off the grid' homestead in Pasadena, CA and supports 4 adults full time. It also produces 3 tons of produce annually. It's all run from solar panels and biodiesel. Over 350 different plants and a handful of farm animals thrive on a 1/5 acre lot, not too far from the middle of Los Angeles. An 'urban homestead' indeed!
Anyone smell a conspiracy? London and the South East gets hit by a massive power cut in a similar way to New York and the surrounding areas. Complaints from authorities in both cities of "under-investment in the National Grid " and talk of "antiquated infrastructure" strangely mirror each other and it's odd that these two extremely rare events have happened so close together. Was this a deliberate test of our emergency infrastructures, terrorism or just plain coincidence?
