Definitions for "Energy Efficiency"
Using less energy to accomplish the same task, such as heating or lighting a building. Using less energy lowers costs and reduces emissions.
technologies and measures that reduce the amount of electricity and/or fuel required to do the same work, such as powering homes, offices and industries.
The amount of input energy required per unit of output energy service provided by an energy-consuming device; also, efforts or activities that aim at reducing the energy used by specific end-use devices and systems, typically without affecting the services provided. Examples include high-efficiency appliances, efficient lighting programs, high-efficiency heating, ventilating and air conditioning (HVAC) systems or control modifications, efficient building design, advanced electric motor drives, and heat recovery systems.
Keywords:  gallon, mpg, input, miles, output
The ratio of energy inputs to outputs from a process, for example, miles traveled per gallon of fuel (mpg).
The ratio of energy output of a conversion process or a system to its energy input.
Energy output of a conversion process or a system in relation to its energy input. Back up

Keywords:  eeca, net, benefits, per, increase
Any change in energy use that results in an increase in net benefits per unit of energy.
Defined by the EECA Act 2000 to mean a change to energy use that results in an increase in net benefits per unit of energy.
The fraction of the energy used in charging the battery, expressed in watt-hours, which is available on discharge.
Ratio of discharged energy to charged energy in one charge/discharge cycle.
The amount of utility, either work performed or income generated, gained per unit of an energy resource.
The capability of doing work; different forms of energy can be converted to other forms, but the total amount of energy remains the same.
the amount of energy extracted from a system divided by the amount of energy put into the system in order to recover the energy.
A measure of energy produced compared to energy consumed.
