{ Wave Power Hiroki Takahashi

 A simple, renewable, clean source of energy produced by waves. What is it?

 Most of the energy comes from the rising and falling water level.  There are many different types of wave powers. How does it work?

Attenuator

Point Absorber

Oscillating Wave Surge Converter

Overtopping/Terminator Device

Submerged Pressure Differential

Bulge Wave

Rotating Mass

{{ Advantages  Predictable  Wave farms can predict about 48 hours in advance with increasing accuracy.  Renewable  Unlimited  Once built: Free (water)  Low maintenance cost.  High supply when high demand (winter)  Not as visible Disadvantages  Very expensive  Limited number of suitable sites  Environmental damage to estuarine sites  Long period of development  Possible effects on ports and industries upstream  When visible, ugly

 Around 10% of Europe’s total wave resource flows in the seas of the Scottish Isles.  Scottish Government calculate about 14 gigawatts of recoverable energy lying in the sea.  Scottish Government sets a target for having 100% of Scotland's electricity from renewable sources by Scottish Islands

 Wavegen is the world leaders in wave energy.  Limpet was placed on the shoreline since  Wavegen supplied the world’s first commercially operated wave plant in Mutriku. (Started in July 2011)  Supplied 16 power units that provide an output of 300kw in total.  Sufficient for around 250 homes. Wavegen
