Electricity Production and Sale
About 30% of all fossil fuel consumed in the United States is
used to make electricity. Conversely, most electricity, about
70%, produced in the US is generated using fossil fuels, especially
coal. Typically, the coal from one or more mines is transported
by railroad or barge to a steam generating plant. Turbine generators
utilize the steam to generate electricity at high voltage. This
electricity is transformed (by a transformer) to a higher voltage
for transmission over a power network to industrial, commercial
and residential users. Near the users it is transformed again,
down to a low voltage, where it is distributed to the users via
the familiar distribution system of poles and overhead wires.
Electricity is distributed by 3 kinds of utilities -- investor
owned, municipal and cooperative. Many IOUs and municipals generate
some of the electricity they sell. Electricity is also generated
by "generation and transmission (G&T)" coops that are owned by
groups of distribution coops. Power is also generated by the federal
government, especially from dams, and by an increasing number
of independent power producers. Since deregulation began in 1992,
a number of independent power marketing firms have emerged as
Investor owned utilities: Edison Electric Institute

Electricity sales to and between investor owned utilities are
regulated by the Federal Energy Regulatory Commission. Most electric power sales to consumers are regulated by the
states. See National Association of Regulatory Utility Commissioners.
