Insight and inspiration in turbulent times.
The Fukushima story is one that will emerge for months and years to come; the worst is behind us, but there are long-term problems that still must be addressed. In our Fukushima Issue, six authors provide a snapshot of where Japan and the international community stand six months on.

BP’s recovery plans following last year’s Deepwater Horizon disaster took a double blow this week. On Tuesday Exxon Mobil and Rosneft announced a deal to develop oil and gas reserves in the Russian Arctic – a version of the very deal that BP thought it had in the bag back in January…
How fast do we need to transition off of fossil fuels? What industrial capacity is available today for different alternative energy technologies and what is likely to be available in the future? What might we do if we can’t replace fossil fuels with alternatives fast enough, and what might the consequences be? I finally got around to re-doing these calculations, and wanted to go through the numbers.
It is becoming standard procedure these days to decry those who oppose you politically as radicals as in “radical agenda,” “radical views,” “radical friends,” and “radical past.” Often this refers to suggested changes in policies that are no more than a few decades old. But I’d like to do something that will seem truly radical to those who are narrowly focused on the contemporary world. I want to look at what might be regarded as radical when considering not the last few decades, but the last 100,000 years.
Markets plunged again on Thursday as warnings of a double dip recession grow louder. Morgan Stanley described the eurozone and the US as “dangerously close to a recession”. Yet oil prices have softened only slightly, and Brent crude remains above $105/barrel…
The key to the future of shale gas is its EROI. I’ve been unable to find estimates of the EROI of shale gas in the literature. However, I’ve made a preliminary first-order estimate that the EROI of shale gas is in the range of 70 to greater than 100. This is probably significantly better than most other energy sources available today.

Let’s face it! The whole fossil fuel thing – widespread use of coal, oil, and natural gas could not have happened without technological advances. Without the steam engine, the coal age would have been limited to a handful of people living near surface coal seams and burning coal for heat and cooking, and perhaps a little metal smelting. All the rest of the industrial age – the internal combustion engine and nearly everything else grew out of some technological development coupled and the abundant energy from fossil fuels.
In my last post, I looked at the Internet’s energy use, broadly construed, and contended that we might offload other societal functions onto the Internet. In this post I’d like to consider in what ways that might be an unwise approach given the dependencies of the Internet.
