Energy efficiency is the practice of using less energy to provide the same amount of useful output from a service (such as heating water, lighting, or cooling a fridge). The EU Energy Efficiency Directive uses a very broad definition: ‘energy efficiency’ means the ratio of output of performance, service, goods or energy, to input of energy. To illustrate these kinds of output, thermal comfort in a building is an example of performance; transport of persons or of information is a . efficient use of final energy or useful energy in industry, services, agriculture, households, transportation, and other areas (see figure ). Supply-side energy efficiency (energy extraction, conversion, transportation, and distribution) is treated in chapters 5 and 8. Supply-side efficiency has been the focus of energy investment and.
