consumption
illconsidered | August 24, 2015August 13th was Earth Overshoot Day. The correct date, if calculated precisely, would come earlier and earlier each year, the current choice is just an approximation.
This year, the year 2015, by sometime around August 13th, humanity had consumed as much of what we require from the lands and seas as our planet can sustainabley provide in an entire year. That is another way of expressing the fact that at current consumption rates, humanity requires 1.6 planet earth's worth of fruits and vegetables, meat, fish, wood and other organic materials. It is a remarkable annual deficit, and if it is…
sastyk | March 19, 2012The always-thoughtful Gail Tverberg has a great post that simply shows in visual terms the history of world energy consumption - well worth a look. I've reproduced one of her graphs here, but please read the whole thing.
One graph not in her post (not suggesting it should be, but I like the contrast) is world discovery of oil over about the same period - anyone who implicitly believes we are discovering vast reserves should contrast the two:

Gail goes on to write about how an economist might be misled by past trends to disregard "facts in the ground" - lack of…
sastyk | December 17, 2010If you haven't seen this video by Richard Heinberg and the Post Carbon Institute, you should. In a lot of ways it is an excellent summary of the history of fossil fuels, entertainingly and creatively done. In some ways, it is extremely valuable as a basic educational piece.
I'm very impressed with the clarity of this video, but it does have an odd gap in it - all of the human history of 300 years of fossil fuels doesn't have a single female person in it - not one. Women are addressed by implication when population is mentioned - but all the little hand-drawn people are men. There is a…
stoat | July 29, 2010A friend pointed out just recently: we usually measure a car's fuel efficiency in Miles per Gallon. But some would like us to switch to the more logical Gallons per Mile (or 10,000 miles, to make the numbers more convenient, or whatever), which would be the fuel consumption. But that, technically, is an area, so for example a car which gets 55ish mpg actually has a fuel consumption of 0.051 mm^2 (ht: A/S).
bcohen | June 10, 2009A slow June at the Fair (see here for an explanation), but I'm popping in to share what constitutes a different sort of landscape image(s) below. Here's the first:
The Citarum River in Indonesia.
Here we have landscapes of garbage, scenes of environments overwhelmed with waste, with excess, with disposed and disposable items. The images are jarring to me, especially when defined as landscapes -- that these are visions of the terrain in which we live. Nobody would confuse these for wilderness pictures. In this case, the human contrivance is too obvious to warrant comment, though In prior…

Landfills are leading consumption indicators. Their use is declining in the recession. The Washington Post reported over the weekend that the Loudon County landfill (that's in Northern Virginia) has seen a decrease of 30% in the past year; nearby Prince William's County has seen a 20% decrease. Loudon County's landfill was slated to close in 2012, filled to capacity by that time. Because of the decrease in consumption--fewer Circuit City boxes to throw away, fewer packages and old appliances, more saving and reuse--it will be open for an additional year and half.
In an extravagantly…
