Almost all the things we use everyday could not be made or used without energy.
Next you may eat breakfast. If you had pancakes or anything cooked, energy from your stove or microwave cooked your breakfast. Now imagine never being able to eat food cooked on a stove. You dinner and lunch couldn't be warm or cooked and would get boring.
Next you will go to school, which involves energy getting there. If you get a ride to school in either a school bus or a car, gasoline is used to power the car. You will probably pass a traffic light on your way to school and that is powered by electricity. Without energy cars would be going all over the place and crashing all the time. Traffic lights help manage the chaos. If you walked to school you used the energy your body made from converting calories from food to energy.
When you arrive at school the bell rings. Energy allowed it to ring. You hear announcements on a loud speaker that is powered by electricity.
Now imagine yourself in a class when someone's cell phone starts ringing. Energy causes this person to get in trouble.
