Energy Efficiency (EE) encompasses all changes that result in a reduction in the energy used for a given energy service (heating, lighting...) or level of activity. This reduction in the energy consumption is not necessarily associated to technical changes, since it can also result from a better organization and management or improved economic efficiency in the sector (e.g. overall gains of productivity).

This definition of energy efficiency is provided by the World Energy Council (WEC) http://www.worldenergy.org/wec-geis
