Answer 2

Electricity has invaded our lives and has become vital in almost all aspects of society today. The list of uses will fill a book but here are a few headings: Transport Trains, buses, trams and cars all use electricity. Many use it as the motive power, meaning that electricity drives the wheels to make the vehicle move. Even gas and diesel powered vehicles use electricity to start the engines, control the engine and power the ancillary devices. Home Heating, lighting, television, radio, computer, telephones all rely on electricity. Even wireless lights such as solar powered lamps will convert sight to electricity. Communication As well as providing power for computers, cell phones, fixed phones, electricity is used as the medium for the transmission of signals. Even high speed optical fibers rely on an electrical signal at each end of the line. Without electricity, communication would be reduced to letters, flag waving and lighting fires and shouting at each other. None of the electricity free methods are as flexible as any that we are used to using today Industry Manufacturing relies on electricity to drive virtually every moving part in a factory. Saws, cutters, conveyor belts, furnaces, chillers - whatever the process, electricity is involved somewhere. Entertainment The MP3 player, the portable battery powered radio, memory stick are all accepted as part of our everyday lives. All rely on electricity to operate. Whether connected to a mains supply or battery, they all use electricity. The list is by no means complete. Take a look around you: if it moves, lights up or makes a noise, it probably uses electricity. (pet dogs and cats excluded of course). Come to think of it, even animals and people use electricity for senses and muscle control, so perhaps the pet dog or cat should be included after all!
