Could you elaborate please?

"Ballistic conduction (ballistic transport) is the transport of electrons in a medium having negligible electrical resistivity caused by scattering. Without scattering, electrons simply obey Newton's second law of motion at non-relativistic speeds."

I read this, had the hope someone could explain this a bit simpler :/

It means electrons travel without bumping into other particles.

Does this imply less power is needed?

There’s no resistance, so it’s almost like a superconductor. No power loss to heat.
