A meta-assessment by Rembrandt Koppelaar argues that "Solar is able to generate 14 times the energy invested to create the panels" while "oil and gas now generate roughly 11 times the amount of energy invested" in the U.S., due to declining reserve quality.
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 world’s most famous and damaging nuclear meltdown is now being considered for the world’s largest solar power plant. “The Chernobyl site has really good potential for renewable energy,” Ukraine’s environment minister Ostap Semerak, 44, said at an interview in London. “We already have high-voltage transmission lines that were previously used for the nuclear stations, the land is very cheap and we have many people trained to work at power plants.”

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."

The only thing green about that bud is its chlorophyll. In California, indoor marijuana grows account for about 9 percent of household electricity use. An indoor grow module accommodating four plants sucks as much electricity as 29 refrigerators. For every pound of pot grown 4,600 pounds of CO2 goes into the atmosphere. The energy needed to produce a single joint is enough to produce 18 pints of beer and creates emissions comparable to burning a 100-watt lightbulb for 25 hours. The production and distribution of pot in America emits as much carbon as 3 million cars. And other fun facts.

From the Netherlands Environmental Assessment Agency... (Interactive Presentation)(Actual Report PDF) Actual global emissions of carbon dioxide (CO2) reached a new record of 34.5 billion tonnes in 2012. Yet, the increase in global CO2 emissions in that year slowed down to 1.1% , which was less than half the average annual increase of 2.9% over the last decade. This is remarkable, as the global economy grew by 3.5%. This development signals a shift towards less fossil-fuel-intensive activities, more use of renewable energy and increased energy saving. Increases in fossil-fuel consumption in 2012 were 2.2% for natural gas, 0.9% for oil products, and 0.6% for coal.

"Over the years, napping has gotten a bad rap, becoming a sign of laziness or weakness, especially during the workday. Yet, according to a growing body of scientific research, napping can actually be a very good and very smart thing to do. How so? Napping can help refresh the mind, make you more creative, boost your intelligence, and even help you live a longer, healthier life. Studies over the past decade have confirmed all of this and more, and napping is slowly gaining acceptance as a part of a healthy lifestyle, even in some corporate offices. Whether you're ready to jump on the nap-happy bandwagon or just learn more about the research being done on the practice, read on as we share the science behind the need to nap, interesting research into napping, and a scientist-approved method for taking the ideal nap."

German Brewers Say Fracking Will Mess Up the Country's Beer (via The Atlantic) Brewing the world's best hefeweizen, you see, requires great drinking water -- and fracking, they said, "could reduce or even completely eliminate the security of the water supply." In a letter (in German), the organization (Deutscher Brauer-Bund) argued that this newfangled way of extracting energy would conflict with Europe's oldest food purity law, the Reinheitsgebot of 1516.
Methane hydrates, also known as clathrates, are crystalline ice structures which trap molecules of natural gas. They are fairly ubiquitous in near-shore seafloor sediments, where methane from decaying organic matter is trapped in an ice structure at low temperature and high pressure. Though methane hydrates are believed to contain substantially more natural gas than conventional deposits, extraction of the natural gas was thought to be impractical. Until now. [more inside]

How can we get CO2 out of the atmosphere? Get it out of the sea first. Making jet fuel from seawater is a pretty cool -- albeit energy intensive -- trick. But applying the same science to scrub CO2 out of seawater, where it is more densely concentrated than in the atmosphere -- and, by doing so, to reduce atmospheric levels of CO2 back to acceptable levels -- that's a game saver.
"what would it take to draw atmospheric carbon down to 350 ppm with just this technology? . . . we would require the power of about 700 AP-1000 nuclear reactors. At the Chinese cost of $1.3b apiece and an 80 year lifetime this would cost a bit over $1 trillion dollars. That sounds like a lot of money. But its only about the cost of America’s 2003 Iraq War spread over the century, so I guess it’s a question of priorities."
