I mean does in use less energy each turn because of momentum?

Yes, it takes more energy in the first few seconds to get it up to speed and then a steady amount to keep it going against air resistance.

As long as it's turning it uses energy from the electricity to generate kinetic mechanical energy.

Once you get past the initial startup period of the fan, it will use the same amount of energy each revolution thereafter.

Once it builds to speed, it uses constant energy; while accelerating to sped, it use more.
