There isn’t going to be enough net energy for the economic growth we want

Post-Carbon Institute: “The really big picture goes like this:  Humans discovered about 400 million years worth of stored sunlight in the form of coal, oil, and natural gas, and have developed technologies that will essentially see all of that treasure burned up in just 300 to 400 years. 

“On the faulty assumption that fossil fuels will always be a resource we could draw upon, we fashioned economic, monetary, and other assorted belief systems based on permanent abundance, plus a species population on track to number around 9 billion souls by 2050.

“There are two numbers to keep firmly in mind.  The first is 22, and the other is 10.  In the past 22 years, half of all of the oil ever burned has been burned.  Such is the nature of exponentially increasing demand.  And the oil burned in the last 22 years was the easy and cheap stuff discovered 30 to 40 years ago.  Which brings us to the number 10.  

In every calorie of food that comes to your table are hidden 10 calories of fossil fuels, making modern agriculture and food delivery the first type in history that consumes more energy than it delivers.”

Capitalism’s destructive car mania detailed

Green Left Weekly: “There is no such thing as a green car… Unsustainable would barely describe the car’s environmental failure if the rest of the world were to adopt US patterns of car ownership and driving behaviour. So why is the car such a protected species, culturally celebrated and immune from radical policy review? Because, the authors say, the car is integral to the capitalist economy and thus any criticism of the car is taboo. Since 1925, the automotive industry has been the leading sector of the US economy, and, of the world’s 10 largest corporations, three are car manufacturers and six are oil companies.”

The Alternative Energy Matrix

Energy score

Do the Math: “A few options are available for the homestead. A passive solar home with PV panels, wind, and some method to produce liquid fuels on site would be a dream come true. Here’s hoping for artificial photosynthesis!

Season’s Greetings

Order coal

There must be some coal left at Bankhead. Maybe not enough to run a railroad, but enough to keep a small town warm. We need a Banff School of Mines.

What Peak Oil Looks Like

The Archdruid Report: “The point that has to be grasped just now, it seems to me, is that this is what peak oil looks like. Get past the fantasies of sudden collapse on the one hand, and the fantasies of limitless progress on the other, and what you get is what we’re getting—a long ragged slope of rising energy prices, economic contraction, and political failure, punctuated with a crisis here, a local or regional catastrophe there, a war somewhere else—all against a backdrop of disintegrating infrastructure, declining living standards, decreasing access to health care and similar services, and the like,”

A Bridge to Somewhere

The Archdruid Report: “The role of ecosystem limits in sustainability is tolerably well understood. Less often grasped, because of its unwelcome implications, is the second category of limits that has to be addressed, which might best be called complexity limits. … This is why, for example, I’ve suggested here that the internet is not going to make it very far into the post-abundance future. To keep the internet up and running takes a vastly complex technological structure, ranging from gigawatts of electricity from centralized power plants, through silicon chip factories and their supporting industries and supply chains, to universities that can train people in the wide range of exotic specialties that keep the net functioning.”

Pedal powered farms and factories

Low-tech Magazine: “One way to solve the large energy losses of pedal power generators is not to produce electricity at all but power devices mechanically, whenever possible.”
