The war on coal is not just political rhetoric, or a paranoid fantasy concocted by rapacious polluters. It’s real and it’s relentless. Over the past five years, it has killed a coal-fired power plant every 10 days. It has quietly transformed the U.S. electric grid and the global climate debate.

So, the apocalypse happens, in whatever flavor you prefer, and eventually our descendants (or the cockroaches') are poised to inherit the earth. Lucky for them, we've left a nice cache of information for them (previously on the Blue) so that they don't have to reinvent the wheel or Pokemon or whatever. Question is, will they be able to do that--or, rather, how difficult would it be to do that--if we use up all the fossil fuels first? [more inside]

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.
How The Economic Machine Works by Ray Dalio actually makes a case against austerity and for redistribution, but also for money printing (and, arguably, for bailouts), while stressing the need to keep making productivity-improving public and private investments.

"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."

A massive shortage of gas all over New York and New Jersey is fueling hours-long lines stretching blocks or even miles. A big part of the problem has been power shortages to gas stations and refineries. Nevertheless, some argue that laws preventing gas prices from spiking in response to the disaster ("price gouging") are making things much worse, discouraging businesses from staying open in tough conditions and preventing entrepreneurs from profiting from any clever ways of increasing supply. Others admit gouging has some advantages, but still consider it ethically dubious. Gouging seems to be happening informally regardless.

Then there's one more way to create a ball and then annihilate one, than to annihilate one and then create one. Huh? Yes: if there are, say, 3 balls in the box to start with, there are 4 balls you can choose to annihilate after you've created one but only 3 before you create one..." [more inside]
