Electricity is an essential part of modern life. People use electricity for lighting, heating, cooling, refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.  

So what is electricity? 

Well it's the flow of tiny particles called electrons. The electrons flow through a wire through the switch and the light bulb and all the way back to the battery. This is called an electrical circuit. A circuit is a word for going around in a repeating state. Electrical circuits have both pressure and flow, the amount of pressure is called voltage. The higher the voltage the more electrons jump. The number of electrons flowing in a wire is called amperage or amps. Amps are like the amount of water that's coming out of a drinking fountain the more amps the more electrons.    

Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.
