WAVE ENERGY

HOW IS ENERGY PRODUCED USING THIS ENERGY?

• Wave energy is produced when electricity generators are placed on the surface of the ocean
• The amount of wave energy generated depends on...
• the wave height, wave speed, wave length, and water density.
• The wave rises into a chamber, forcing air out. The moving air spins a turbine which turns a generator.

HOW MUCH IS IT USED IN NZ?

• Wave energy is a successful energy source in NZ.
• In 2007 there were 20 wave and tidal projects under development.
• The greater Sook Strait and Kaipara Harbour are promising locations for under water turbines.

HOWMUCH/WILL IT BE USED?

WHAT ARE THE MOST LIKEY PLACES FOR THIS ENERGY?

• The Kaipara Harbour as it is one of the largest harbours in the world.
• The Cook straight as it has tidal flows among the strongest in the world.
• Wave energy needs to be located some where with windy weather...
• Stormy weather create big strong waves that generate the most energy.

POSSIBLE EFFECTS ON THE ENVIRONMENT...

• Disruption of the movement do large marine animals.
• Disrupts fish migration.
• Kills marine life that try pass through the turbines.
• Possible noise pollution.
