Hofmeister, president of Shell, on global warming-
"It's a waste of time to debate it. Policymakers have a responsibility to address it. The nation needs a public policy. We'll adjust."
The energy future, he said, will include fuel derived from...unconventional sources, biofuels, wind and solar energy, hyrdogen fuel cells, and conservation. He said the U. s. with 8% of the world's population is using 25% of the energy, "It's not a sustainable formula."

Similar remarks have come from British Petroleum and others.

The oil companies "will adjust." They exist to provide services that the public wants and to make money for stockholders.
If the future is fuel cells, or whatever, they will shift. But unless there are public and government policies directed toward change, they will continue to do what is necessary to make money for their stockholders (ultimately you and me) by providing services we want.
