Electricity comes from other energy sources that are converted to electricity so that we can use it. In Texas, the energy sources are coal, natural gas, uranium/nuclear fuel, wind, solar and gas from landfills. These energy sources are transformed to electricity by generators. Transmission lines carry electricity from where it's made to places called substations in different towns and neighborhoods. These substations contain equipment that reduces electricity’s voltage, so it can travel on smaller distribution power lines that branch out down streets or alleys and underground to homes and businesses.
