Responsibility and long term planning have never been a part of that, because they cramp their ability to pile up the cash and party.
The problem with a Green Strategy is that opportunities for making a big stinking pile of cash are more limited than they would be in other areas - which is not to say that they're not available, but no one is going to get as much of an adrenaline rush from building a windfarm as from building a planet-spanning derivatives empire which could implode at any moment.
Green energy is measured, intelligent, sensible and mature, which makes it utterly the wrong choice if you're one of the Econo's consumers of financial crack.
