Lowering demand is the only effective response to lower supply.  That is the message peak oilers could emphasize now.  They wouldn't lose their audience if they adjusted to this new reality.

Peaksters!  Give up the "Mad Max" screaming about the end of cheap oil.  Admit that if demand drops in conjunction with supply, our oily GHG economic war on terror problems would evaporate into thin air.

Climb on the GHG tipping point scream wagon and talk up demand reduction as the only way out.  Electric transportation can drop oil demand steadily year after year, and GHG along with it.  Look out for the resultant economic boom.
