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).
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.
Energy Efficiency: Buildings and Industry
Energy efficiency is the use of less energy to perform the same task or produce the same result. Energy-efficient homes and buildings use less energy to heat, cool, and run appliances and electronics, and energy-efficient manufacturing facilities use less energy to produce goods.
Energy Efficiency
Simply put, energy efficiency means using less energy to get the same job done – and cutting energy bills and reducing pollution in the process. Many products, homes, and buildings use more energy than they actually need, through inefficiencies and energy waste.

2024年1月12日 · Energy efficiency generally pertains to the technical performance of energy conversion and energy-consuming devices and to building materials. Energy conservation generally includes actions to reduce the amount of end-use energy consumption.
Energy efficiency
Energy efficiency refers to attempting to get a desired energy service using less primary energy (either primary fuels or primary energy flows). This goal is usually based on having less of an environmental impact and often attempts to be more sustainable, although sometimes people are seeking energy efficiency to save money.
