From Barron's - "Because of deals signed in just the past year, companies like BP, Shell, Exxon, and Chevron are building enough offshore wind farms to supply millions of homes on the East Coast with electricity and are preparing to produce hundreds of millions of gallons of fuel made from plants, garbage, and kitchen grease. They’re increasingly confident that they can get greener without sacrificing profits.

A gusher of cash this year makes that an easier task. Oil companies are taking advantage of sky-high commodity prices to pay down debt, fund capex and shareholder returns, and invest in low-carbon businesses of the future. Worldwide, total investments in renewable energy is on track to exceed oil and gas investments for the first year ever this year."

So, some of the oil companies see the writing on the wall. OTOH, Shell is doing a buy back rather than lowering prices.
