Since a state would need (for many years into the future) a backup power system (i.e. the current fossil fuel electrical system), the price comparison needs to be between the price of natural gas and the wholesale solar farm price of electricity.
A household’s energy needs need to be met via a well-thought-out system involving all electrical devices of the household. This has not been done because such systems would eliminate the existing fossil fuel system and the need for the unionized local electric company.
Wrong.
