Customers used to only receive electricity and natural gas supply from their local utility, but thanks to energy choice, customers have the power to choose more than just a great rate. Scientifically, electricity is the flow of electrons from one atom to another, creating a charged current. One of the most widely used forms of energy, electricity is used in the application of heat, light and power. Electricity occurs naturally, for example, though lightning, but is most commonly generated using both renewable and non-renewable sources of energy. Renewable, or “green,” energy refers to electricity which is generated using natural resources that continually replenish, for example, wind, solar and water. Non-renewable, or “brown” energy refers to electricity which is generated using resources that do not renew at a sustainably sufficient rate, for example coal, natural gas, and uranium. Generation or power plants are used to convert those energy sources to electricity. The electricity produced by a generator travels along cables to a transformer that changes it from low voltage to high voltage, allowing it to travel long distances more efficiently. Transmission lines are then used
