Key Terms

Alternative Energy 
Any source of energy other than fossil fuels that is used for constructive purposes.
Ampere 
The unit of electric current in the meter-kilogram-second system of units. Referred to as amp and symbolized as A.Biomass  Plant materials and animal waste used especially as a source of fuel. 
Current 
The net transfer of electric charge (electron movement along
a path) per unit of time. Electrical Energy Energy caused by the movement of electrons.Electricity The flow of electrical power or charge.
ElectromagneticInduction
The production of electricity in conductors with the use ofmagnets.
Efficiency 
The ratio of the useful energy delivered by a dynamic system to the energy supplied to it. 
Energy 
A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work.
Energy Conversion 
Changing one form of energy to another. 
Environmental Protection Agency
An organization that works to develop and enforceregulations that implement environmental laws enacted by Congress.
Fossil Fuel 
A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Generator 
A dynamo or similar machine for converting mechanical energy into electricity. 
Geothermal Energy 
The use of heat from within the Earth or from the atmosphere
near oceans.
Gravitational Energy 
The state when objects are not yet in motion.Induction The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body. 
Inexhaustible Energy 
An energy source that will never run out.
Kinetic Energy 
Energy which a body possesses by virtue of being in motion.
Nonrenewable Energy 
A resource that cannot be replaced once used.
Ohm
The unit of electric resistance in the meter-kilogram-second system of units. Symbolized as Ω.
Ohm’s Law 
States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit.
Parallel Circuit 
A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit.
Potential Energy 
The energy that a piece of matter has because of its position
or nature or because of the arrangement of parts.
Power Converter 
Changes one form of power to another.
Power Grid 
A system that links electricity produced in power stations to deliver it to where it is needed.
Renewable Energy 
A resource that can be replaced when needed
.
Resistance 
The opposition that a device or material offers to the flow of direct current.
Work
A result of a force moving an object a certain distance.
Turbine 
A machine for producing power in which a wheel or rotor is made to revolve by a fast-moving flow of water, steam, gas, or air. 
Power
The rate at which work is performed or energy is expended. 
Rotor
The rotating member of an electrical machine. 
Series Circuit A circuit in which all parts are connected end to end to provide a path of current.
Volt
The unit of potential difference symbolized as V.
Voltage 
The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit.
