Energy Efficiency
Introduction
Energy Efficiency
Energy efficiency is the practice of using less energy to achieve the same level of output. It is an important concept in today's world as it plays a crucial role in reducing energy consumption, lowering energy costs, and mitigating the negative impact of energy production on the environment. Energy efficiency is a key component of sustainable development and is essential for achieving a more sustainable and greener future.
Overview
Energy efficiency is the ratio of useful energy output to the total energy input. It is often measured in terms of energy efficiency ratio (EER) or coefficient of performance (COP). EER is the ratio of the cooling capacity of an air conditioner to the power input, while COP is the ratio of the heat output of a heating system to the power input.
