What is the “it” here?
EmDrive looks like an accounting error to me, not something that actually works. Any energy it expends turns into heat, radiating in a predictable but not necessarily isotropic way. This radiation carries momentum, but much less than the EmDrive claims to be capable of.
A rocket or ion drive? The energy goes into the kinetic and gravitational potential of the exhaust.

(Aside: kilowatts are power, not energy).
