Energy Efficiency | Frenly Earth

Energy efficiency refers to the ratio between the useful energy output and the input of a machine or system. It is a crucial aspect of reducing energy consumption and mitigating climate change. Energy efficiency can be applied to various fields, including physics, electrical engineering, mechanical engineering, and transportation. By optimizing energy efficiency, individuals and organizations can minimize energy waste, reduce costs, and promote sustainable development. The concept of energy efficiency has been widely adopted globally, with many countries implementing policies and regulations to promote energy-efficient practices. Energy efficiency is a key component of the United Nations' Sustainable Development Goals (SDGs), particularly SDG 7, which focuses on affordable and clean energy. The International Energy Agency (IEA) promotes energy-efficient practices. The residential sector will account for the largest share of the global energy efficiency market by 2025.
