Kelly David Burke has the sorry tale in a recent Fox News article.

The Bush administration had set aside 1.3 million acres for oil shale and tar sands development in Colorado, Utah and Wyoming.  The new Bureau of Land Management plan cuts that amount by two-thirds, down to 700,000 acres….

I’ll elide Burke’s poor arithmetic—the 600,000 acre reduction amounts to a reduction of a bit under 50%–he is, after all, a journalist; his point remains valid: this is an enormous reduction in oil resource availability.

President Barack Obama’s BLM has its excusesrationale all lined up though.  It’s

…not against oil shale and tar sands development, but will restrict the amount of public lands available for leasing until the processes are proven, and proven safe.

Never mind that Canada has been successfully and safely extracting oil from shale and from tar sands for decades, and US companies have been extracting from shale for nearly as long with similar success and safety.

This is, in the end, just part of Obama’s effort to artificially suppress the price of otherwise unviable solar and wind energy sources with enormous subsidies and loans while trying to restrict the supply of oil (and gas) in an attempt to price these sources up into the stratospheric range of even the subsidized “green” energy…sources.

It’s all of a piece with his decision elsewhere to slow walk oil leases and drilling permits.
