Drone/fighter defences:
Everyone has phasers, tractors and t-bombs, so no need to list them.
Federation: Dual purpose G racks and fighters - energy cost=0
Gorn: a small number of D rack equipped ships - energy cost=0; late on, PFs - energy cost=0
Hydrans: fighters - energy cost=0
ISC: a small number of D rack equipped ships, and fighters - energy cost=0
Klingons: AMD and fighters - energy cost=0
Kzinti: AMD and fighters - energy cost=0
Lyrans: ESG - energy cost=5, late on, PFs - energy cost=0
Romulans - as Gorn - energy cost=0
Other than PFs, every weapon on a Lyran ship requires energy to use. The Hydrans are similar except for the fact that they have attrition units from the start, not to mention their hellbore ships have the most power.
