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]
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.
Low-Tech Magazine and No-Tech Magazine have some fairly well written/illustrated articles about old and low technologies. The concept being, in a sustainable future due to environmental constraints, carbon taxes, Peak Oil, etc.. these old-school technologies might be used - in some places, in some form - instead of more energy intensive modern high technology. Trolly Canal Boats, Timbrel Vaulting (vs. steel and concrete), Bring Back the Horses (and the bicycle), Tile Stoves, Wind Powered Factories, Sneakernet, more.
Revealed: the environmental impact of Google searches - "Physicist Alex Wissner-Gross says that performing two Google searches uses up as much energy as boiling the kettle for a cup of tea."
Inconvenient Truths: Get Ready to Rethink What It Means to Be Green. Last month, Wired published what it called "10 green heresies" which makes the case for urban living, intensive forest management and, er, air conditioning, among other things.
Dead Ringers: the Science Museum asks us the question "should we upgrade our mobile phone?" "No" and "no" say the Times and the Observer, but we still do: on average every 18 months. What's the problem? Well it isn't just the lead, arsenic, beryllium and brominated fire-retardant cases (pollutants all) disappearing into our land fills (which are not covered by the Waste Electrical and Electronic Equipment Directive [WEEE] in Europe). Coltan also goes into our phones. It occurs mainly in the Democratic Republic of Congo, and as such our demand for upgrades has been contributing to a war (despite mobile phone companies' claims to the contrary, coltan is not regulated like timber). If we must upgrade, we can at least recycle or hack our old phones.
