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.

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.

EXAMPLE PICTURES

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.

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.

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.

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?
