What Is Dirty Electricity?
Dirty electricity refers to surges and spikes of electromagnetic energy traveling along power lines and building wires where only standard (“clean”) AC electricity should be. This type of EMF pollution is also known as dirty power, electrical noise, line noise, and power line EMI (electromagnetic interference).
Dirty electricity is created by consumer electronics, modern appliances, energy-efficient lights, and quite a few other items that run on electricity. Why? Because many of these devices no longer use standard AC electricity “as is.” Instead, they must change or “manipulate” electrical current in one way or another in order to operate.
For example, many electrical devices today must convert standard 60 Hertz, 120 Volt (or 50 Hertz, 220-240 Volt) AC electricity (alternating current) into other forms of electricity [such as lower voltage direct current (DC) or higher frequency AC] in order to operate. And, many devices now draw power intermittently, in short bursts, rather than continuously, by turning the flow of power to a device “on” and “off” repeatedly, sometimes thousands of times per second.
These processes interrupt the smooth flow of standard AC electricity, creating harmonics and spikes of electrical energy known as voltage transients. Once created, this unusable “dirty electricity” can spread throughout a building and to other buildings via wiring, power lines, and other means. As it travels, dirty electricity radiates potentially harmful electromagnetic fields into environments where people live, learn, work, and more.
