Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton, and the number of electrons in an atom is usually equal to the number of protons. When the balancing force between protons and electrons is upset by an outside force, an atom may gain or lose an electron. When electrons are "lost" from an atom, the free movement of these electrons constitutes an electric current.
Electricity is a basic part of nature and it is one of our most widely used forms of energy. We get electricity, which is a secondary energy source, from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. 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 slightly 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. In the mid-1800s, everyone's life changed with the inventionof the electric light bulb. Prior to 1879, electricity had been used in arc lights for outdoor lighting. The lightbulb's invention used electricity to bring indoor lighting to our homes.

Introduction on electricity consumption?
There has been a growing emphasis on conservation and protecting the environment. Not only does conservation help to preserve the planet, but it can also save you money on your utility bills. When you conserve electricity, you are helping to maintain our ecosystem, protect our natural resources and put a few dollars back in your pocket. In many cases, conserving electricity takes some simple steps.

When did electricity come to Australia?
The first public demonstration of electricity in the form of lighting in Australia occurred in Sydney as early as the 1830s, thanks to a strong push by Governor Bourke. However, electricity was not readily available to houses or anywhere else then. The introduction of electricity was a gradual thing, and it wasn't until 1863 that the city of Sydney was lit up to mark the occasion of the wedding of the Prince of Wales. Electric lighting was only used regularly in Sydney, the largest city, from 1878.
