Last time I've checked, every transformer dissipates EMF into its surrounding environment, and radiates a tremendous amount of infrared energy. How can something be considered efficient, when a tremendous amount of energy gets converted into heat, and acoustic oscillations. Please, don't pretend like you have a clue, because you clearly don't. I've been working on this my whole life!
I assumed you were speaking of the industry standard full load power efficiency. That is Efficiency equals ((power in - loss) / power in) * 100%. The loss is dissipated as heat. Here's a short article on it.
