Even if America tomorrow - and it won't happen overnight - but if we did reduce our demand for gas and natural gas and crude oil by a significant degree, that does have an exponential effect on producers in the Middle East, everything else being equal.

The financial crisis just made the hole deeper, which is why our stimulus needs to be both big and smart, both financially and educationally stimulating. It needs to be able to produce not only more shovel-ready jobs and shovel-ready workers, but more Google-ready jobs and Windows-ready and knowledge-ready workers.

What if we're wrong and there is no climate change? Well, by doing everything possible to address it, we will still use less water, stimulate new energy savings and, in time, money-saving technologies, enjoy cleaner air, and preserve more forests and trees and animals.

If we don't have a more serious energy policy, the difference between a good day and bad day for America from here on will hinge on how the 86-year-old king of Saudi Arabia manages...change.
