1) Electricity results from the presence and flow of electrical charge.
2) It is a secondary source of energy, meaning that it is produced from coal, oil, nuclear power and other sources of natural energy.
3) To provide us with heat, light and power, electrical energy has to be converted. The energy that comes from electricity, like all forms of energy, can never be destroyed.
4) The generation of electricity began just over 100 years ago.
5) The word electricity comes from the New Latin electricus, "amber-like" from the classical Latin electrum from the Greek word elektron meaning amber.
6) Even the Ancient Egyptians were aware of electricity, but its power wasn’t really understood until the 18th century.
7) The first principals of electricity were developed after Benjamin Franklin conducted an experiment in Philadelphia in 1872. He is reputed to have attached a metal key to the bottom of a dampened kite string and flown it in a stormy sky. He observed a succession of sparks from the key to the back of his hand, showing that lightening was electrical in nature.
8) The light bulb was invented by Thomas Edison in the late eighteenth century. Today, the production of light is one of the biggest domestic uses of electricity in the UK.
9) Indeed, we weren’t able to get electricity in our homes until Nikola Tesla pioneered the use of alternating current (AC) electricity, rather than direct current (DC) electricity, which can be transmitted over much greater distances.
10) In 2001, the Department of Transport and Industry reported that our use of electricity just keeps getting bigger. That year, the UK consumed electricity equivalent to over 240 million tonnes of oil, more than it had in the last thirty years!
