It wouldn't be an entirely apples-to-apples comparison to jet fuel. A fully-electric VTOL aircraft would ditch most of the wings, for instance, and instead make the fuselage lifting-body. Wings are large to provide enough lift at takeoff and landing speeds, tail and rudders to provide aerodynamic stability which would be provided by electric motors instead. Also, the engines would be lighter and a significant fraction of the empty weight would be batteries. We wouldn't see an electric drop-in replacement for a long-distance airliner in the near future, no one is claiming that.
