The definition of electricity is the flow of charge. Usually our charges will be carried by free-flowing electrons. Negatively-charged electrons are loosely held to atoms of conductive materials. With a little push we can free electrons from atoms and get them to flow in a generally uniform direction.

Where does electricity come from for kids?
We get electricity from sources like coal, energy, natural gas and oil. Electricity is a secondary source of energy, which means it must be made from these items. We have learned how to take items that we find in nature or products like oil and transform them into the electricity we need to power our homes.
