The list of equipment, appliances, and other devices that produce dirty electricity seems endless. Nearly anything we plug in and turn ON today has the potential to generate this type of EMF pollution. This is particularly true of devices that are energy efficient, include a switch mode power supply, and/or have an electric motor (especially a variable speed motor/drive). The box to the right shows examples of common dirty electricity sources in homes and other settings.
