People have used coal, oil, and gas for hundreds of years. One day, these fossil fuels will be gone. Luckily, scientists have many ideas about energy for the future.
It's important that people try to save energy. Design a poster for your class to explain how they can use less energy. Be sure to include: • a catchy heading; • ideas on how to save energy; • facts about energy; • a labelled diagram showing things that use less energy.
