it seems also disingenuous that the environmental impact at origin of the imported oil is completely ignored, and the same applies for other imports including consumer goods or even "green energy" related devices and materials (batteries, solar panels, etc)

also the US has a variety of conditions for prospection, CA being one of the worst places for new prospection projects - so this also needs to be taken into account

PS: at 3$/gallon I suspect the majority of consumers were already not taking gas consumption lightly, so while it's true that energy savings are a crucial part of the picture, they were already very heavily incentivised for a while in the US and certainly here in Europe as well
