Energy means the power we get from things like coal, wind, water, and sunlight that we can use to do things like make electricity or run machines.

At home, we use different types of energy. We use electricity for lights and appliances. We also use gas to cook and heat our homes. The electricity mostly comes from things like coal, wind, water, and sunlight.

Renewable sources are things like wind, water, and sunlight that we can use to make energy. Unlike coal, which we can run out of, renewable sources can be used over and over again.

To save energy, we do things like turning off lights when we're not using them, using less hot water, and using energy-saving appliances. We can also use things like solar panels or wind turbines to make our own energy.
