What is They waste energy?

They waste energy when they use more power than they need to do something simple.

Imagine you're pushing a toy car across the floor. If you push it really hard, like you’re trying to run after it, you’re using a lot of energy, but the car just goes a little faster. That’s like wasting energy, you used more power than you needed, and the result isn’t that much better.

Think about eating your favorite snack. If you eat it all in one bite, you might not enjoy it as much. But if you take small bites, you savor every flavor. Wasting energy is like eating the whole snack at once, you’re using up all your power quickly, and maybe you’ll feel tired faster.

Sometimes people or machines use more energy than needed because they don’t know better, it’s like trying to push a toy car with both hands when one hand would do. Or maybe they think using more energy will help them finish faster, but really, it just makes them tired quicker.

So, wasting energy means using more power than you need, kind of like eating your snack too fast!
