Green Energy - What Does It Mean? GREEN?

Some smart people have found a smart way to harvest energy. And they belief that this harvest is green, though it comes from driving cars. This raises the following questions:
Can Green Energy be harvested from a White Boy? From Black, Yellow or Red people? From Semitic or Anti-Semitic ones? Buddhist, Muslim, or Christian ones? Wicca Witches, Madonna Qabbalists? Taliban Toyota's? Berlusconi Bicycles?

Do cars have to be green to create green energy?
Well, when it comes to harvesting energy, it seems that all racial, cultural, political, religious and other perceived distinctions - for example colour - are not at all important; just the way it should be in the perfect world we do not live in ... have not succeeded to achieve/create.

But with oil having been shown recently to be beyond PEAK already, any such thinking-outside-the-box idea may be valuable.

Naturally, it would probably all work even better if the cars creating this green energy would perhaps even drive using green energy in the first place.
Here's an article explaining the concept, including a video with a soundtrack for the deaf.
I can't help it ... you'll probably have to turn your sound down.
