What Is Energy And Where It Comes From

Science Interactive lesson Free to play

Energy is the ability to make things happen — to move objects, give off light, produce heat, or make sound. Nothing changes or works without it: a running child, a glowing lamp, a warming heater and a ringing bell are all energy at work. Energy also comes in different forms, such as movement energy, light energy, heat energy and sound energy, and it can change from one form into another.

Most of the energy around us can be traced back to the Sun. Plants use sunlight to grow, animals and people eat plants for the energy stored in food, and that stored energy lets the body run, think and play. Energy sources fall into two groups: renewable sources like sunlight and wind that never run out, and non-renewable sources like oil, coal and gas that will run out one day. Matching sources to what they power — sunlight to a solar panel, wind to a turbine, a battery to a phone — shows how the energy we use every day is collected, stored and put to work.

What this Spark covers

Frequently asked questions

What is energy in simple terms for kids?
Energy is what makes things happen. Anything that moves, lights up, heats up or makes a sound is using energy to do its work.
Where does most of our energy come from?
Most energy on Earth starts at the Sun. Plants capture sunlight to grow, and that energy passes into food, fuels and many of the things we use each day.
What is the difference between renewable and non-renewable energy?
Renewable sources, like sunlight and wind, never run out. Non-renewable sources, like oil, coal and gas, will eventually run out because there is only a limited amount.
How does food give us energy?
Food stores energy that originally came from the Sun. When you eat, your body releases that stored energy so you can run, think and play.
What are the main forms of energy a child should know?
Common forms include movement energy, light energy, heat energy and sound energy. Energy can also change from one form into another, such as a battery turning stored energy into light.
