Geologists have determined that world-wide natural gas production, with fracking could produce enough for hundreds of years usage.

When I was growing up here in the 1960s, after the boom of the 1950s, experts said we were never going to discover any more oil.  The boom of the 1970s proved that wrong.  Then in the 1980s, it was all over but the shouting.  Guess what?  Technology improved and now we have more oil and gas than we know what to do with.  Even now, older horizontal wells (five years old) are having new technologies applied to them, boosting their output.  Just go to the North Dakota Industrial Commission/Oil and Gas Division and look at the production numbers. Do a Google search on it!
