Green energy hasn't failed. There are companies and/or types of the whole going green thing that have done well. You have to take into account the shitty economy, everyone is doing poorly, except the oil companies of course.
What I want to know though, for the people who keep pushing oil oil oil, which isn't going to lower prices on gas fyi if they do more drilling, what happens when we run out of oil? Not one of you have come up with an idea of what we do after that. Thats why the whole 'green movement' thing is going on. So we can get other sources of energy up and running BEFORE we run out.
