- 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.
- Electromagnetic Induction - The production of electricity in conductors with the use of magnets.
- 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 enforce regulations 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 single 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.
