When electrical energy is used what type of enegry is also produced to be waste energy?

When electrical energy is used, waste energy is often produced in the form of thermal energy or heat. This occurs due to inefficiencies in electrical devices and systems, where some energy is lost as heat during operation. Additionally, mechanical energy can also contribute to waste energy in systems involving moving parts, where friction generates heat. Overall, these forms of waste energy signify energy loss in the conversion and use processes.
