Energy efficiency refers to the endeavor of minimizing the amount of energy required to provide products and services. It represents the ratio of useful energy output to total energy input. As an illustration, a highly efficient light bulb produces the same amount of light as a less efficient bulb but consumes less electricity.
Pursuit of this goal yields numerous benefits, encompassing reduced energy consumption, decreased greenhouse gas emissions, and cost savings for individuals and organizations. Historically, improvements in this area have been driven by technological advancements, government policies, and growing awareness of environmental concerns.
