2. Contents • Why we need Renewable energy? • How wave energy works? • Example pictures • Advantages • Disadvantages • Future • Quiz (have you been listening carefully?) • Question Time • Thanks

3. Why do we need renewable energy • We need renewable energy because we need to make the world cleaner. • We also need renewable energy because we need to make the world a better palace. • We need renewable energy because we need to stop using fossil fuels.

4. How wave energy works. • Wave energy work be a fixed devices are fixed to the sea bed or the seashore, for example the Limpet on the Scottish island of Islay. • The Limpet was the world’s first large wave power machine. • The limpet can supply electricity to about 350 homes. • Inside the limpet is a wells turbine this special turbine turns in the same direction regardless of which way the air moves.

6. advantages • Once constructed, running costs are very low. • No waste or pollution is produced. • Wave-energy generators are capable of producing large amounts of energy.

7. Disadvantages • Wave energy generators are only effective where they are exposed to strong waves. • They can be noisy. • Wave energy generators may be a hazard to ships to leisure craft.

8. Future • In the future there might be more wave energy inventions. • In the future the more wave energy invented the more hazards to ships. • In the Future there might be more waves.

9. Quiz (how was listening carefully) • Why do we need renewable energy? • How does wave energy work? • What are two wave energy machines? • What is the 2nd disadvantage?
