Power lines are located high overhead or buried underground. Proton A basic particle in an atom's nucleus that has a positive electrical charge. Solar energy Electricity produced from the sun's radiation. Substation A facility where transformers lower electricity's voltage. Transformer A device used to increase or decrease electricity's v oltage and current.
Transmission lines Power lines that carry high-voltage electricity long distances.
Turbine A device used in the generation of electricity. It has a shaft with blades at one end and electromagnets at the other. Water or steam or some other energy source pushes the blades, which make the shaft and the magnets spin very fast. The magnet end is surrounded by heavy coils of copper wire, and the spinning magnets cause electrons in the wire to begin to move, creating electricity. Utility A company or other organization that provides a public service, such as supplying electricity, natural gas, or water.
