A funny thing happens when an industry starts growing. If you look at trends throughout history, progress tends to be exponential.
What that means, toppy, is that there are things that will happen in even the next 5 or 10 years which will completely surprise even those who are currently working on green technologies. There will be mechanisms & innovations on methods of harnessing & distributing alt energy that aren't even being talked about right now.
And here you are, guaranteeing that oil will still dominate 4 decades from now, based on...the restaurants being full? What, exactly?
LOL
