1) Wind-turbine factory worker
While factory workers building cars are losing sleep these days, those lucky enough to be on a wind-turbine line are getting a solid eight hours of sleep a night. Wind power is the fastest-growing source of energy in America and all those turbines need to be built by someone. Modern turbines are highly engineered machines and require hundreds of hands to get from blueprints to installation. With wind power showing no signs of slowing down, building wind turbines is a great (and secure) way to pay the mortgage.
