Energy input labeling is when we put labels on things to show how much energy they use. Think of it like putting a sticker on a toy to show how much it costs. Except, in this case, we're sticking labels on things like light bulbs, refrigerators, and other things that use energy.
You know how sometimes you turn on a light and it's really bright, but sometimes it's not as bright? That's because different light bulbs use different amounts of energy. Some light bulbs use a lot of energy and some use less. By putting labels on them, we can see how much energy they use and choose the one that is most efficient.
It's kind of like trying to decide which candy to eat. If you have a bunch of different candies in front of you, you might want to choose the one that has the least sugar or is the healthiest. Labels on energy-using things help us make similar decisions, but instead of focusing on sugar, we're looking at how much energy it takes to use them.
So, if you see a label on a refrigerator, it will show you how much energy it uses in a year. If you see a label on a light bulb, it will show you how bright it is and how much energy it uses. By knowing this information, you can make better choices about what energy-using things you want to buy or use, and it helps us all to save energy and protect the environment.
