Answer:
Electricity is the flow of electrical power or charge. It is a secondary energy source which
means that we get it from the conversion of other sources of energy, like coal, natural gas,
oil, nuclear power and other natural sources, which are called primary sources. The energy
sources we use to make electricity can be renewable or non-renewable, but electricity itself
is neither renewable or non-renewable.
Electricity is a basic part of nature and it is one of our most widely used forms of
energy. Many cities and towns were built alongside waterfalls (a primary source of
mechanical energy) that turned water wheels to perform work. Before electricity
generation began over 100 years ago, houses were lit with kerosene lamps, food was cooled
in iceboxes, and rooms were warmed by wood-burning or coal-burning stoves. Beginning
with Benjamin Franklin's experiment with a kite one stormy night in Philadelphia, the
principles of electricity gradually became understood. Thomas Edison helped change
everyone's life -- he perfected his invention -- the electric light bulb. Prior to 1879, direct
current (DC) electricity had been used in arc lights for outdoor lighting. In the late-1800s,
Nikola Tesla pioneered the generation, transmission, and use of alternating current (AC)
electricity, which can be transmitted over much greater distances than direct current.
Tesla's inventions used electricity to bring indoor lighting to our homes and to power
industrial machines.
Despite its great importance in our daily lives, most of us rarely stop to think what life
would be like without electricity. Yet like air and water, we tend to take electricity for
granted. Everyday, we use electricity to do many jobs for us -- from lighting and
heating/cooling our homes, to powering our televisions and computers. Electricity is a
controllable and convenient form of energy used in the applications of heat, light and
power.
