-- If NG becomes scarce and/or expensive, then alternative methods are available and will be used. That's capitalism! What besides nukes? Isn't the other constaint the needed fresh water? I don't mean to be negative -- lousy as tar sands are, need may make inevitable a big ugly operation with nuke plants and artificial lakes the size of Iowa to exploit tar sands at terrific cost to try to extract oil at a reasonable rate. - Charles

there are several tested methods (some partially still under technical development) for extracting and refining Canadian bitumen which require NO natural gas. If NG becomes scarce and/or expensive, then alternative methods are available and will be used. Extracting the stuff will still require enormous amounts of energy. What energy source(s) will these methods use, and do these methods have EROEI ratios comparable to that of producing bitumen with NG? If these alternative extraction/refining methods ultimately rely on fossil fuels, then we have a problem... Jesse
