We've noted previously the problems North Dakota was having finding trained workers - a problem other states wish they had (see here, e.g.). Both the WSJ and the Philadelphia Inquirer have similar articles mentioning the need in other areas with active production (see here and here). From the Inquirer: "Run - don't walk, run - to Marcellus Shale natural gas drilling areas if you are a welder or pipe fitter or engineer or a company that can deliver such people to companies already operating in the fields."
Energy = Jobs.
