What is renewable energy?
Renewable energy is made from resources that nature will replace, like wind, water and sunshine. Renewable energy is also called "clean energy" or "green power" because it doesn't pollute the air or the water.
What are conductors? Give an example.
an object that makes a closed circuit and allows electric current to flow. Metals are conductors.
What is the main source of energy on Earth?
The sun
