What is energy efficiency? Definition and examples
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).
Efficient energy use - Wikipedia
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.
Energy Efficiency - Understand Energy Learning Hub
Energy efficiency is providing the same or better service using less energy. Energy services are all the benefits we derive from energy use, such as illumination, thermal comfort, cooking, transport of people and freight, and many industrial and agricultural functions.
