Exxon=Oil: Why Exxon Mobil Doesn't Care about Alternative Fuels

Unlike its rivals, Exxon Mobil doesn't much care about alternative fuels and doesn't try to please the greens. Is CEO Rex Tillerson nuts - or shrewd?

FORTUNE, April 30, 2007 — Rex Tillerson is way out of line, and he knows it. "They want us to join the parade," he says, referring to assorted environmentalists, scientists, politicians, investors and others who've been lambasting him and the company he heads, Exxon Mobil. He knows what they're saying about him, and he repeats it: "Get in line. You're outta line right now - get in line."

Why Tillerson refuses to run Exxon (Charts, Fortune 500) the way other CEOs are running other giant oil companies is for many people the most baffling and even infuriating question about the world's most profitable corporation.
