This stat can also be atttributed to many other factors that may or may not be at play here (eg. wealth distribution, age distribution, etc...) I'm not saying they would skew the results, I'm just pointing out that overall consumption is still on the rise and it outpaces domestic production.
??? You mean that, what, the average linear consumption trend for the last several decades is up? Sure, but I hope we agree that recently this is not the case, that the recent consumption figures are
US Consumption, 4 wk average, all oil, mbpd
Feb 2007 21.8 (all time high US consumption)
Feb 2008 20.6
Feb 2009 19.5
Feb 2010 19.3
Feb 2011 19.4
Feb 2012 18.1
i.e. off 17%, otherwise I'm wasting my time here against some kind of dogmatic belief unchangeable by data.

The bulk of oil sands production has come from mining operations to date. Along with that, however, are the SAGD operations. These produce volumes much less than mining operations do (on a one to one comparison), but collectively will account for greater amounts of total contribution to oil sands production. These operations require drilling, thermal processes to create steam, pipelining, etc... and are far less concentrated than mining operations. So, even if energy requirements are decling now they will increase again. SAGD operations will likely account for ~80% of bitumen produced throughout the course of oil sands development.
Perhaps, but in the future we don't know if SAGD will be used over (say) VAPEX that does not require steam. With very cheap natural gas to make steam no doubt SAGD will continue for awhile, but there's no rule mandating that will be the case.

They are falling, but they have only been falling for the last 2-3 years of a 61 year upward trend. As I mentioned above this kind of aberration does not mean much of anything until it becomes a long-term trend. At the moment, it can be explained away by many other factors.
I respect long term trends. The flip side of long term trends is that reversals never seen before have significance. That's why I see a six year reversal 25% off the peak as significant.

I don't think I said land-use always rules out the concept of biofuels (if I did, I apologize). I think I indicated that land-use issues will be an impediment to these sorts of operations. There are many sectors vying for space and it is very difficult to justify large extents of land for low relatively volumes of fuel.
<shrug>I don't know that commercial interests are vying for the vast tracks of barren land in the US, at least they have not so far. Certainly there are groups that want these areas left barren and pristine.
