The amount of electrical energy needing to be stored for three winter

72Twh is around 62 megatons of energy. Slightly larger than the
biggest
hydrogen bomb ever detonated*.

I make it about 26Kg of energy.


Kg is a unit of mass.
Not energy

but E=mc^2

Quite, he started it by talking about megatons of energy.
Megatons is an established energy unit related to 'million tons of TNT
equivalent' and is used to describe high magnitude energy releases from
nuclear weaposns through earthquakes to volcanoes.


No one uses mas to represent energy in any sphere but deep nuclear physics.


Teh fact that three months electricity represents the permanent loss of
26kg of fissile material from the universe, may be true - I haven't
checked - but its isn't really releavant, beyond showing just how high
energy density nuclear reactions are.
