Oh, and here's a non environment one.

A major topic of interest to the man (or woman) at the wheel is the price of gas. You said last time how this was majorly driven by the world oil prices, which we recognise is in turn driven both by sentiment and supply/demand mismatches.

What research has the API done to predict how the world markets in oil will react to differing levels of supply contraint - and thus how oil prices would be affected to deliver differing levels of demand destruction? How high does that price need to be to effect demand destruction in the US?

As an example, if demand needed to be reduced by 3Mbpd tomorrow, what level would the API expect the price of oil (and gas) to have to rise to to achieve that effect in today's market?

Great question...seconded.
