"Professing themselves to be wise, they became fools" - Romans 1:22

[HoreTore]

Surprisingly enough I agree with Horetore's principle. If they make less money off fossil fuels and more off sustainable sources, they'll choose that. Image is important as well and companies will do anything to get ahead, even taking a loss to ensure future profits.

Transportation is an obvious example on this. The cheaper my train is and the more costly my car is, the more likely it is that I will take the train to work instead of driving.

Of course there are exceptions to this as well, economic incentitives don't always work as intended(morals also play a part, for example). And of course, I sold my car in 2010. I didn't do it on economic grounds, I did it for moral reasons... Been a happy pedestrian ever since!
