Our house is all electric and we average 750 KWH a month. I don't know anyone in our area with a bill that low that doesn't use natural gas on top of it. Our monthly minimum with Entergy appears to be around $45.
The overall natural rate of unemployment will then be affected by changes in the demand or supply in these different segments of the overall labor market and by changes in the composition of the aggregate labor force. Several major changes in recent decades have affected labor supply and demand.
This level of real GDP is called the Natural Level of real GDP. The Natural level of real GDP is also associated with the natural rate of unemployment. Now I have already shown, here and here, that the effective demand limit determines the natural rate of unemployment. It then follows that the effective demand limit determines the natural level of real GDP too.
