SpaceX is optimizing costs rather than energy-efficiency. Obviously you need less fuel if you're not doing a soft-landing back.

Energy efficiency also needs to consider how much energy you need to build the vector. It looks quite likely to me that reusing the vector would be more energy efficient too.

Energy efficiency means many different things. It's tricky to estimate if the total energy efficiency is smaller using a reusable rocket. Could be.
