Ideal System (aka a perfect world)Energy is not lost to friction or leaking.
In short energy is conserved and perpetual motion works

Real WorldEnergy is lost to friction
Energy is lost to the production of other forms in conversion processes (such as sound and heat)
Energy is still conserved just we can convert 100% of it into the intended form
