		Electric power, like mechanical power, is represented by the letter P in electrical equations, and is measured in units called watts (symbol W), after Scottish engineer James Watt.
		Electricity is transmitted from remote electricity generation power plants and sold to end consumers by retailers via electric power transmission and electricity distribution.
		It is necessary to transmit the electricity at high voltage to reduce the percentage loss of power over long distances: for a given cable the loss of power is proportional to the square of the current, while for a given transported power, this current is inversely proportional to the voltage.

	Electric power transmission - Wikipedia, the free encyclopedia
		Typically power transmission is between the power plant and a substation in the vicinity of a populated area.
		Power is transmitted underground in densly populated areas (such as large cities) but is typically avoided due to the high capacitive and resistive losses incurred.
		AC power transmission is the transmission of electric power by alternating current.

		In 1878, Thomas Edison (United States inventor; inventions included the phonograph and incandescent electric light and the microphone and the Kinetoscope (1847-1931)) developed and sold a commercially viable replacement for gas lighting and heating using locally generated and distributed direct current (An electric current that flows in one direction steadily) electricity.
		Increasing the voltage (The rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts) reduces the current (A steady flow (usually from natural causes)) and therefore reduces resistive losses in the cable.
		Today, Tesla's alternating-current electric power (additional info and facts about alternating-current electric power) system is still the primary means of delivering electrical energy to consumers throughout the world.

		The amount of electrical energy used by an appliance is found by multiplying its consumed power by the length of time of operation.
		Electrical energy is of little use unless it can be made available at the place where it is to be used.
		Power losses incurred in transmission from heat and electromagnetic emissions are included in the total reactive power requirement as are the needs of power hungry devices, such as electric motors, electromagnetic generators, and alternators.

	Electric Power eTool: Glossary
		Electric circuit: Path followed by electrons from a power source (generator or battery) through an external line (including devices that use the electricity) and returning through another line to the source.
		The commutation of power (conversion from DC to AC) is controlled by the power line, so that, if there is a failure in the power grid, the Photovoltaic system cannot feed power into the line.
		Photovoltaic (Photovoltaic) conversion efficiency: The ratio of the electric power produced by a photovoltaic device to the power of the sunlight incident on the device.

	Electric Power (Site not responding. Last check: 2007-10-22)
		The electric power in watts associated with a complete electric circuit or a circuit component represents the rate at which energy is converted from the electrical energy of the moving charges to some other form, e.g., heat, mechanical energy, or energy stored in electric fields or magnetic fields.
		The resistor is a special case, and the AC power expression for the general case includes another term called the power factor which accounts for phase differences between the voltage and current.
		The fact that the power dissipated in a given resistance depends upon the square of the current dictates that for high power applications you should minimize the current.

	Electric Power Steering
		Honda went with an electric power steering system mainly because (1) It's compact and light and (2) it's not parasitic (robbing power from the engine) since it only draws electric power on demand.
		Honda reduced the size of their original power steering unit in '95 to make it about 4 pounds lighter than the original ones in the '91-'94 automatics.
		If the steering wheel is turned and held in the full-lock position and steering assist reaches a maximum, the control unit reduces current to the electric motor to prevent an overload situation that might damage the motor.

		Research is also underway to increase the fuel efficiency of coal-fueled power plants. Today’s plants convert only a third of coal’s energy potential to electricity. New technologies in DOE’s Fossil Energy program could nearly double efficiency levels in the next 10-15 years. Higher efficiencies mean even more affordable electricity and fewer greenhouse gases.
		The 103 U.S. nuclear units supply about 20 percent of the electricity produced in the United States – second only to coal as a fuel source. The Nuclear Energy program is working to develop cost-efficient technologies that further enhance nuclear safety, minimize the generation of nuclear waste, and further reduce the risk of proliferation.
		But "superconducting" materials have no resistance, and if they are used to transmit electricity in the future, very little of the electricity will be lost.

		In other words, the utilities want to be assured that they will recover, in the rates you are charged for electricity, the costs of a plant that may appear to be needed today but may not be needed when it's completed.
		Finally, the utilities are proposing to assess customers who have chosen an alternative provider for their electricity a charge for not only new plants but existing generation as well, allowing utilities to drive competitors out of business.
