My college students are usually sucked into the "scarcity" theories

Then tell them about the Green River deposits... According to the US Geological Survey in Feb this year the deposits weigh in at 3 Trillion Barrels of oil....with 1 Trillion Barrels recoverable with today's technology.,...

and for the Peak Oil fanatics...1 Trillion Barrels of oil is about equal to the entire world's known reserves of oil.

“Green River deposits”

Now you are talking about some REALLY expensive oil. It is not really oil but kerogen that must be converted into oil.
