Review: The Biochar Debate by James Bruges

by

It’s called biochar, and if you believe its most ardent supporters, then this unassuming, fine black powder is a vital tool in the solutions to some of humanity’s most urgent ecological threats, including climate change, peak oil, soil degradation and water pollution due to agrochemicals. However, if you side with biochar’s staunch opponents, then it seems like a fledgling, poorly understood technology with real risks, including the displacement of entire communities and the serious jeopardizing of world food security and biodiversity. Which view is correct?

BBC on the impact of biofuels on Paraguay’s ecology and farmers

by

Everyone should listen to this BBC report on the “price of biofuels.” It digs into a key question: what does Europe’s appetite for biodiesel mean for people and ecosystems in the countries that produce the feedstocks?

Deepshit Horizon: Earth Day began with a blow-out, will it end with one?

by

On January 28th, 1969 the Union Oil Company’s Platform A, located six miles from Santa Barbara, CA experienced a “blow-out.” Highly pressurized deposits of natural gas pushed upward against the newly bored well causing oil to leak from the pipe and casings…The blow-out was devastating. Ironically, and tragically, this year’s Earth Day celebrations coincided with another oil rig blow-out, this time offshore of Louisiana. Like other recent mining disasters, the explosion and sinking of the rig caused by a well blow-out has claimed the lives of at least eleven workers.

Energy follows its bliss

by

The predicament of industrial society unfolds to a large extent from its mishandling of energy issues. Because of that, the laws of thermodynamics — and no, to borrow a phrase, they’re not merely suggestions — have to be taken into account in any attempt to make sense of the economics of the approaching deindustrial age.

Commentary: The Redundant Subsidy

by

Even for staunch proponents of U.S. biofuel policy, it is hard to argue that the current subsidy on grain ethanol serves the purpose it was designed to serve. With ethanol mandates now in place in the form of the Renewable Fuel Standard (RFS), there is a mechanism – with penalties for non-compliance – to ensure that gasoline blenders use the mandated amount of ethanol. Maintaining a subsidy on top of a mandate would be like paying people to obey the speed limit.
