Businesses Investing in the Environment?

This can't be possible, can it? I thought corporations were root of all evil, manipulating workers and polluting the environment. But now I read that:

Corporations have found that environmentally friendly technologies often allow them to eliminate waste and lower manufacturing costs, thus improving their financial performance. Wider use of envirotech can even avoid future liabilities for workers' health problems, says Bill McDonough, who has helped design environmentally friendly manufacturing facilities for the likes of Ford and shoe maker Nike (NKE ).

This is why I think it is ridiculous when people worry about us running out of oil. When oil gets scarce, the price will go up significantly, and businesses will scramble to find alternatives. But, as long as the price stays low, it makes no sense to invest in a different energy infrastructure.
