Energy efficiency

Definition

Energy efficiency refers to the practice of using less energy to perform the same task or provide the same service, resulting in reduced energy consumption and lower environmental impact. This concept is particularly relevant in the context of technology advancements, as improved energy efficiency often leads to cost savings, enhanced performance, and reduced greenhouse gas emissions. In LED technology, energy efficiency is a key factor that drives innovation and application across various sectors, making lighting solutions more sustainable and economically viable.
