Power Electronics largely consists of screeching waves of feedback, analogue synthesizers making sub-bass pulses or high frequency squealing sounds, and screamed, distorted, often hateful and offensive lyrics. Deeply atonal, there are no conventional melodies in Power Electronics. The term "power electronics" was originally coined by William Bennett as part of the sleevenotes to the Whitehouse album Psychopathia Sexualis, and is related to the early industrial records scene but later became more identified with the noise music scene.
A style of "P.E." called "Heavy Electronics" is usually the same tonally, with grim subject matter, but seemingly without the racial-centric lyrics.
