THOUGHTS ON THOSE CANADIAN TAR SANDS:

At a time when saying anything good about fossil fuels is like declaring war on the environment, it may seem like wishful thinking to press for an expansion of U.S. oil refining capacity.

Yet it is precisely this sort of thinking that is necessary if we are to make use of a vast, secure and reliable supply of fuel from Canada’s oil sands.

The tar sands hold an estimated 174 billion barrels of crude oil, making Canada’s oil-sands deposits second only to Saudi Arabia in global reserves. The U.S. currently obtains 1 million barrels a day from Canada’s tar sands, but with planned investments the daily supply could exceed 3 million barrels by 2015.

Seems like we should be making those. Then there are reports — which I still regard as iffy, though much of the blogosphere seems excited about them — regarding a potentially just-as-big discovery in the Bakken oil formation of North Dakota. I certainly hope they’re true, and we’ll see. There’s also lots of oil shale in Colorado.
