  • How the Electricity Grid Works | Union of Concerned Scientists

    Transmission lines carry high voltages because it reduces the fraction of electricity that is lost in transit – about 6% on average in the United States . As electricity flows through the wires, some of it dissipates as heat through a process called resistance. The higher the voltage is on a transmission line, the less electricity it loses.
