Relay types that requires the least energy

What type Relays that requires the least energy to operate:
a.Induction-disk relay
b.Polarized dc relay
c.Moving-coil dc relay ?
d.Induction-cylinder relay

We know that most EMR relays don't required external power supply. But instead operate by electromagnetic coils, or electromagnetic attraction, and electromagnetic induction.
do all DC relays are more efficient than AC ?
