Yeah, no one has managed to harness more energy out of a plasma than put in to make it yet, but technically if it’s doing fusion at all, there’s more energy created though with current technology most of it just goes out into the universe as entropy that’s not harnessed. Unless of course, as other posters mentioned, you consider the energy as present in the matter in the first place, which is a reasonable way to model it too. ¯\_(ツ)_/¯
