the rest of the decline
"The rest of the decline was in jet fuel, diesel, the power sector"
Diesel and jet fuel are also used more efficiently. Total passenger miles isn't down - planes are just more full and more efficient. Total ton-miles of freight isn't down, it's just being used more efficiently. Total kwHR of electricity consumed isn't down, it's just produced more efficiently. Over and over, it's the opposite of what you're saying - relative to 2005, these aggregate indicators of economic activity are up, and yet total fuel consumption is down. And yet your explanation is the total fuel consumption is down, because total economic activity is down. When someone points out to you that total economic activity is up and not down, you get mad and say "find the mistake in my analysis".
And yet you wonder why Yergin gets all the talk shows and the book deals.
