If we ran out of fossil fuels which could replace them.
No single one of these resouces, at their current levels, could totally replace out energy consumption.
yeah but which could almost do it
None of these. To even come close they would all have to be combined and have much more capital invested into them.
Solar is the only energy source available world wide. This does not address all the matereial products we get from Petrochemicals, such as plastic, etc. as such none of the choices are viable.
