Three commonly used types of renewable energy are solar energy, wind energy, and hydro water energy.

Solar energy is energy that comes from the sun.

You probably have seen large mirrors in solar power plants that collect sunlight.

But did you know that this is only the first step of getting solar energy?

Heat from concentrated sunlight is used to boil water.

This creates steam, which rotates turbines connected to an electric generator.

That's where electricity is created.

Interesting, huh?

Just like this, the power of wind and water rotates turbines,

which are connected to electric generators.

They produce electricity.

Fossil fuels, such as oil, are becoming scarcer,

and the need to find alternative sources of energy has become more urgent than ever.
