Carnegie Wave Energy Limited has allowed Australia to be one of the few countries to use generators in transporting electricity across a naval base. The testing of the system occurred in Fremantle, New South Wales in early 2015 at a cost of $100 million.
The CETO 5 wave energy generator is made up of 240 kw buoy tethered to a water pump. It is converting the movement of the high powered water into electricity. The power grid can function for 14000 straight hours and it has been observed that it has channeled zero emissions. There were two buoys placed on the seabed. And a plan for a third expected to be implemented by mid-2016.
Advantages of wave energy
With this new wave system, it is possible that electricity will never run out as the system has a renewable source. As it is the fossil fuels are being exhausted rapidly and scientists are busy looking for a new source that will not run out.
Scientists who have approved the system are consistently calculating the amount of energy it is discharging. The system is proven to be better with no dependence on sun and wind exposure. Employment opportunities have opened up for scientists across the nation regarding testing and approval.
Disadvantages of wave energy
Wave energy still creates hazard under water for some of the crustaceans that live in the water. Since large machines have to be placed on the seabed to gather energy from the waves above, this disturbs the sea floor and changes the habitats of some of the creatures such as crabs and starfish. Loud noises from this machine are being emitted causing disruption to the sea life around them.
Power plants that gather wave energy must be placed near the shoreline for them to operate effectively, this will create noise pollution and disruption in the daily lives of residents living near the shore. The beauty of the coastline will potentially be affected by the operation as well as the physical presence of the plant.
Australia is not the first country in the world to have this renewable energy source placed on their shores. Portugal was the first in the world to have a wave farm officially opened on September 2008. However, the bad news for Portugal was the financial collapse they experienced that year forcing them shut off the system completely. The United Kingdom and the United States are the two other countries that have this system apart from Australia.
