Exxon is suing Venezuela for nationalizing their facilities after they were told to leave and refused to comply. Venezuela as a result will be refusing to export fuel to the US and is promising other countries - who wants to bet Iran? - will support them. Gas seems like it may get a lot more expensive because there is no way Bush and Co. will not destroy this country protecting Exxon. Situations like these are why the US is moving to bio-fuels; efficiency and cleanliness has nothing to do with it.
This is a good time to be doing what we are doing. Getting cars more efficient, off gasoline, and even learning to use our own strength again.
