Answer:
every electrical item
Step-by-step explanation:
Every user of electricity, including lights, heaters, stoves, cell phones, computers, refrigerators, and on and on, will turn electrical energy into some sort of electromagnetic radiation.
The radiant energy we're usually wanting is energy in the form of heat or light (or radio communication).
We purchase wi-fi products, space heaters, and light bulbs specifically because of the kind of radiant energy they produce. For most other electrical products, the production of radiant energy is incidental to the purpose for their use, and not the main purpose.
