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."

GrowUp: the future of food - "The new concept of commercial aquaponics, argue Hofman and Webster, has a much-reduced environmental impact. Companion farming fish and crops dates back to the Aztecs, but it took until the 2010s, in Chicago, to move it indoors at any scale. In the UK, only eco-smallholdings have so far attempted it, and the only European aquaponics farms of note use purpose-built greenhouses. GrowUp's model, by contrast, is to fit out empty urban buildings, use no chemicals, employ LED lights, source 100 per cent renewable energy and, crucially, be based within five miles of its customer base in a dense urban area."
The world's coral is suddenly and rapidly starting to die - "This is only the third time we've seen what we would refer to as a global bleaching event. [The prior events] were in 1998 and 2010, and those were pretty much one year events. We're looking at a similar spatial scale of bleaching across the globe, but spanning across at least 2 years. So that means a lot of these corals are being put under really prolonged stress, or are being hit 2 years in a row." Can 'manually breeding supercorals capable of living in increasingly inhospitable waters' help in time? (via/via)
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]
Let Us Face the Future - "All parties pay lip service to the idea of jobs for all. All parties are ready to promise to achieve that end by keeping up the national purchasing power and controlling changes in the national expenditure through Government action. Where agreement ceases is in the degree of control of private industry that is necessary to achieve the desired end. In hard fact, the success of a full employment programme will certainly turn upon the firmness and success with which the Government fits into that programme the investment and development policies of private as well as public industry."

UN Climate Report: We Must Focus On 'Decarbonization', and It Won't Wreck the Economy - "The basic message is simple: We share a planet. Let's start acting like it." [more inside]
Free Money for Everyone - "A wacky-sounding idea with surprisingly conservative roots may be our best hope for escaping endless, grinding economic stagnation." (via) [more inside]
How to feed 9 billion people: The global food supply is starting to get tight, with increasing sensitivity to droughts and floods causing price spikes and food shortages. The UK commissioned a report to examine how to feed a planet with a population that is set to increase to 9 billion by 2050. [more inside]
Get the Energy Sector off the Dole - Why ending all government subsidies for fuel production will lead to a cleaner energy future—and why Obama has a rare chance to make it happen.
