Question 8

Why is renewable energy important for the environment?

Accepted Answer

Renewable energy is important because it doesn’t pollute the air or water like burning coal or oil does. It helps keep our planet clean and safe.

Question 9

Can renewable energy help with climate change?

Accepted Answer

Yes, renewable energy can help with climate change because it doesn’t produce harmful gases that make the Earth hotter. Using clean energy can help protect our planet's future.

Question 10

Are renewable energy sources expensive?

Accepted Answer

At first, setting up solar panels or wind turbines can cost a lot. But once they’re in place, the energy they make is usually cheap or even free.

Question 11

What are some challenges with renewable energy?

Accepted Answer

One challenge is that the sun doesn’t always shine and the wind doesn’t always blow, so we need ways to store the energy. Another challenge is building enough of these systems to power everyone’s homes and schools.

Question 12

Can we run out of renewable energy?

Accepted Answer

No, renewable energy sources like the sun and wind don’t run out. They are always there for us to use.

Question 13

How does using renewable energy affect animals and plants?
