Sun, Wind, Water, Oil
Open to everyone until Tuesday, September 29
To keep it, print it while it is open.
Sunlight, wind, and flowing water are replaced by nature. Oil, coal, and gas are limited and make dirty smoke when burned.
In the picture
- The sun: sends light and heat that can be used again and again.
- The wind turbine: turns moving air into electricity.
- The river dam: uses flowing water to make electricity.
- The oil pump: brings up oil, a fuel that is limited and cannot be replaced quickly.
Examples
- A rooftop solar panel makes electricity from sunlight.
- A car burns petrol made from oil and sends smoke out of its exhaust.
Key takeaways
- Sunlight, wind, and water keep coming back naturally.
- Oil, coal, and gas are limited and cause more pollution.
