The basic idea behind energy efficiency is to use less energy to accomplish the same task. It's similar to managing your energy wisely to avoid wasting it.Example:Try to portray two different light bulbs. They both give off the same amount of light (the same "job"). But one bulb uses way less electricity than the other to do it. The one that uses less electricity is more energy-efficient.Overall, making things function without using excessive amounts of energy is the main goal. Energy efficiency is achieved by using less gas, electricity, or whatever energy source is used to achieve the same outcome, such as a cool house, a lit room, or a clean load of laundry. The goal is to reduce waste.Important Points:Same outcome with less energy.minimizes waste.Conserves funds.Good for the environment.
