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