Testing begins for first offshore wind farm
Nov 13^th, 2019 at 10:20am

Lets hope the brain dead LNP does not try and sabotage this desperately needed project !

Testing begins for first offshore wind farm in Australia

Scientific testing begins this month for Australia’s first proposed offshore wind farm, near Gippsland, which could provide enough power for more than 1.2 million homes.

The testing comes as the union movement launches a campaign to lobby the state and federal governments to smooth the way for the project to proceed.

The Star of the South wind farm is expected to provide up to 2000 megawatts of power − about 18 per cent of the state’s power demand − and is set to cost between $8 billion and $10 billion.

Within weeks, the company will begin detailed studies of the wind and wave conditions at the 496-square-kilometre area off the south coast of Gippsland. It will also conduct environmental studies on marine and bird life.

If considered feasible, the wind farm is slated to provide “full power” by 2027.

Unions hope the wind farm will provide secure jobs for electricity workers in the Latrobe Valley, where the economy has relied heavily on coal-fired power generation.

The Latrobe Valley was hit hard by the closure of the Hazelwood power plant in 2017, and remaining coal-fired power plants are scheduled to begin closing in coming decades.

The broader region is bracing for more job losses with the state government phasing out native timber logging by 2030, sparking a furious response from the Construction Forestry Maritime Mining and Energy Union.

Previous estimates indicated the Star of the South wind farm could include 250 turbines but that is yet to be determined. Its proposed site is between 10 kilometres and 25 kilometres from Port Albert......

It's more expensive to build them out in the ocean but on the flip-side there is more constant source of wind. Either way you are not setting fire to costly polluting coal Wink

Putting these bird choppers offshore also makes them more expensive and difficult to service.

How much coal do they have to burn to produce the steel used in these bird choppers?

How much fossil fuel has to be burnt to mine the products needed to manufacture these bird choppers?

Also, the blades can't be recycled.

I wonder if they sent the memo to Bob Brown?

"He says it is in the wrong place, will ruin the view and kill endangered birds like the Tasmanian wedge-tail eagle and the white-breasted sea eagle that live on the island, and potentially migratory birds like the swift parrot and the orange-bellied parrot that travel between Tasmania and the mainland."

https://www.abc.net.au/news/2019-07-25/bob-browns-opposition-to-wind-farm-labell...

The island is Robbin Island, those eagles may not be affected by this.

"Unions hope the wind farm will provide secure jobs for electricity workers in the Latrobe Valley, where the economy has relied heavily on coal-fired power generation."

Well coal loaders need not apply, nor the high pressure vessel blokes.

Not a "wind shadow", they remove wind energy.

"Every turbine removes energy from the winds, so that many turbines operating over large scales should reduce wind speeds of the atmospheric flow. With many turbines, this effect should extend beyond the immediate wake behind each turbine and result in a general reduction of wind speeds. This wind speed reduction is critical, as it lowers the amount of energy that each turbine can extract from the winds. "

They don't put wind turbines behind other wind turbines.

What about them? we have plenty of land and sun.

The more wind turbines the better.

Wind turbines and paddocks of solar panels are entirely different. One needs wind, the other needs sun. Grin

So when the wind stops and it rains and the sun goes behind a cloud ... and you want to watch something on TV. What happens? Turn on the what?

Apart from which wind forced around a wind turbine loses directionality and therefore force as the wind strikes at slightly different angles.

They are strategically placed using wind velocity for their viability.
