I don't know what level I should try to explain this. Can you tell me
where you are in technical background?

Ok, based on evolutionary biology (you can include memetics) explain the
rest of the variance.

I think you are not including the rapid increase in China's consumption.

I agree. I see two approaches that don't contribute to the greenhouse gas
problem and are on a scale to replace oil. Do you see others?
