As long as we don't run out of oil. Unlike global warming, this issue is not a conspiracy theory, it is an obvious fact. The only question is When?

If you are young, better consider that. There are technical solutions to that problem, but our national leaders have been slow to develop these, for a variety of political and economic reasons. We cannot even get a reasonably believable estimate of how much is left...everyone who has the means to come up with such an estimate also has a possible motive to skew the results.

Our industry leaders, not surprisingly, have taken a stance which bears a striking resemblance to a large, flightless bird. Of course none of them even plan to be around in 5-7 years, so why worry

When oil prices skyrocket for real, we had better have an alternative infrastructure already in place or the economic damage will end this profession for most of us. Things will recover eventually, there are enough alternatives, but it could take decades.
