The Dirty Electricity Story
The
sheer volume of modern electronics and appliances in homes and other
settings has increased at a dizzying rate. While, this proliferation of
electrical devices has made our lives more efficient and convenient, it
has also contributed to a potentially harmful form of electro-pollution
known as DIRTY ELECTRICITY.
Dirty electricity is unusable electromagnetic energy that is created
by many electrical devices as they operate. It is caused by
interruptions in the flow of normal 60-Hertz AC (alternating current)
power traveling through wires and electrical systems in homes and other
buildings. These interruptions result in voltage spikes, or surges, as
well as frequency variations (also called high frequency voltage
transients) that combine to form a complex and potentially harmful
electromagnetic field.
Many modern electronics and appliances include transformers that
convert the AC power in a building’s wiring to the DC power needed to
run electronics and appliances. During this conversion process,
interruptions in electrical current flow occur. In addition, many modern
electronic devices (e.g., light dimmer switches, compact fluorescent
light bulbs, equipment that use switching mode power supplies) utilize
power in a more complicated way than more “old-fashioned” electronics
and equipment. These devices are actually designed to operate with
interrupted electric current flow. Rather than draw power continuously,
they do so intermittently in variable amounts at a high frequency,
primarily for efficiency. While this can save energy, it involves
frequent interruptions in electric current flow. For example, a compact
fluorescent light bulb saves energy by turning itself on and off
repeatedly, thousands of times per second. Regular interruptions like
these create transients (i.e., voltage spikes/surges and frequency
variations) that “dirty” the normal electricity flowing along wires.
What happens to dirty electricity once it is generated?
The dirty electricity created by electrical devices within a building
is circulated throughout the building, and even to other buildings in
the neighborhood, via wiring. It radiates into the immediate environment
via outlets, power strips, electronic devices, and cords/wires,
exposing the humans inside to electromagnetic pollution.
