Offshore wind power generation doesn't get much attention here, but a report has found it has big potential, with promising sites close to existing sub-stations.

Australia has huge potential to develop offshore windfarms near existing substations, report says | Wind power | The Guardian (https://www.theguardian.com/environment/2021/jul/22/australia-has-huge-potential-to-develop-offshore-windfarms-near-existing-substations-report-says?CMP=Share_AndroidApp_Other)

Its great yet scale to replace existing demand and add new demand needs a few more options I read. More wind the better. Happily it usually is stand alone in cost not needing the Bucket load or Government (Taxpayer ) funding that coal and even gas is seeking. Germany as 25% wind power now UK is similar. Adding another 75% via wind may be a bit tricky I think. Adding more to replace the gas grid for heating makes it very unlikely to meet the full demand.

Not against wind in any way. It is not our full solution is my only point.

Somewhere like Gladstone is brilliantly placed to add wind and solar to connect to the existing strong power grid and use the renewable power for aluminium smelting, hydrogen and produce other products which are carbon free and will be exempt from foreign carbon taxes. It is re-industrialising and could create a lot of new jobs.

There has a been a project talked of here off the coast north of Bunbury, by a big multinational investor. The coast here is only 20m deep for 20km offshore, with highly reliable winds, close to metro area infrastructure. Bring it on I say...

There are some wind energy electric generators in Tassie.

The west and nor west are just perfect for these generators, being in the 40deg. Latitude. and really not that far from main distribution conductors.

Any problems ? Yep NIMBY🤨

Biggest problem is the 'current' current capacity of the cable to the mainland @ 490 mW.

Needs to be at least doubled now to really make sense even without adding more wind generation in Tas.

I reckon that should be MW .. not mW!! .. but I think most of us understood what you meant! [thumbsupbig]

Technical ,engineering,structural ‘ problems’ can all be fixed.

what is very hard to surmount , is this NIMBY attitude , now my land is not affected so I am not emotionally or financially or legally concerned.....
if these wind energy generators where in some persons backyard then I might sympathise , but the proposed sites are remote enough to not be under the NIMBY blanket.

I think we all have a bit of NIMBY in us. I cannot run around the park as there is too many people getting an hours walking in[biggrin] Happily never mind the road running which I have 90%plus to myself



Bob B nimby is not unexpected. Love wind mills if they are far enough away I cannot hear the creaking, from the old style water pump types I mean of course.

Has been for quite awhile, direct to SA.

Connecting all the excess wind and solar on the mainland with the biggest 'battery'.

Happens now, but the connection needs to be at least double.

Agree, gutsy effort indeed, and if presented as that alone, great.

But I think it also shows the hypocrisy of the human condition, including those that actually think that having 2 ICE 4wd's for 1 person is viable alternate energy.

To quote.

"We had a support vehicle in front and [a] support vehicle behind to make sure I didn't get squished … by passing cars or motorbikes."

"I want to raise awareness about the damaging effect of our carbon emissions on our sacred wilderness and show how we can make changes for the better."

Does make me a bit pessimistic, but maybe I've just had a below average day

The 1,500MW Marinus link is scheduled to be started in early 2025 - but (there's always a but) - final funding hasn't been signed off, but funding is 'anticipated' to be signed off by the end of 2024. With current supply issues in Vic and other areas, it is at the top of AEMO's wish list so will almost certainly happen, but I won't believe it until it's done. It will run up into Gippsland and pick up the transmission network in Morwell - which is one of the strongest points in the network given the amount of power that is/has been generated there.

They are doing a lot of community consultation at the moment and have had stalls at various places - I had a chat to them at Farm World a couple of months back. Cable is going to run underground all the way to avoid the catastrophe Ausnet have found themselves mired in over the west of the State with its transmission line proposal. It wasn't their preferred option (due to cost I'd imagine) but they've had exactly zero percent support for above ground transmission as you'd expect in this day and age.

The new interconnector (project Energy Connect) that's currently being build between Wagga Wagga and Roberstown will be able to move a lot more around between the States as needed and funnel a lot more solar and wind into the network. The VNI interconnector between Kerang and Wagga Wagga (Or Buronga - it's final route isn't set in stone yet) will get what comes in from Marinus to the rest of Eastern grid - due for completion around the same time as Marinus.

So I'll get back to you around 2030 when this is all sorted... [biggrin]

"Germany fears a wave of insolvencies | Germany | News and in-depth reporting from Berlin and beyond | DW | 08.09.2022 (https://www.dw.com/en/germany-fears-a-wave-of-insolvencies/a-63059812)"

I like wind power. It is available about 50% of the time twice my solar PV availability time . Capacity compared to availability is a item Germany overlooked "At the end of 2021, a total of 28,230 onshore turbines with a combined capacity of about 56 gigawatts (GW) were in operation across the country. With a gross expansion of about 5.3 GW, the year 2017 had the strongest capacity growth so far (https://www.wind-energie.de/presse/pressemitteilungen/2018/ausbauzahlen-fuer-das-gesamtjahr-2017-deutschland-windenergie-land). Expansion then dropped to less than 1 GW in 2019 and 1.6 GW were added in 2021. The new expansion target is an annual capacity addition of 10 GW by 2025 and a total installed capacity of 115 GW by 2030."

German total consumption in 2018 may have been 512,934,000,000.00 kWh (2018) thats "512 934.00 gigawatt hours (GWh)"

Assuming Germany can by 2030 have capacity of 115 GW by 2030 it will be 20% ish assuming power use goes done - we all know power use is likely to go up!

"Germans call it Energiewende (https://en.wikipedia.org/wiki/Energiewende) (“energy transition”), and they aim to decarbonize their economy and lead the world by replacing their fossil fuel and nuclear plants with renewable energy." " Germany spent nearly 202 billion euros (https://www.bloomberg.com/news/articles/2021-01-12/germany-paid-record-38-billion-for-green-power-growth-in-2020#xj4y7vzkg) on renewable energy projects from 2013 to 2020. Since 2010, the share of German electricity generation that has come from solar and wind power has risen from 8 percent to 31 percent (https://www.iea.org/countries/germany)"

The full time/part time is NOT part of that! Capacity compared to availability is a item Germany overlooked

"Germany’s anti-nuclear ideology is so rigid that they closed three nuclear plants in December 2021 (https://www.euronews.com/2021/12/31/germany-begins-nuclear-phase-out-shuts-down-three-of-six-nuclear-power-plants#:~:text=Under%20Germany's%20energy%20transi tion%20policy,decommissioned%20on%20December%2031% 2C%202021.), despite the global energy crisis"

If you want a perfect case study on spending Trillions to fail Germany is probably it? Any way the Wind blows. The poms are capping power bills to $2000 pounds a year for 6 months. Cost to their taxpayers is more than likely to be $4000 pounds + less the 2000 house holds may/will pay.

Carbon free is needed. Not putting money into whats needed. Government misfire by directing subsidies to options that are part time only and do not work to enable the changes needed.

Carbon Trivia time- a very cool year for this black duck has the most cited paper by "Manabe & Wetherald ( 1967 (http://journals.ametsoc.org/doi/abs/10.1175/1520-0469%281967%29024%3C0241%3ATEOTAW%3E2.0.CO%3B2)) With eight nominations, a seminal paper by Syukuro Manabe and Richard. T. Wetherald published in the Journal of the Atmospheric Sciences in 1967 tops the Carbon Brief poll as the IPCC scientists’ top choice for the most influential climate change paper of all time.

Entitled, “Thermal Equilibrium of the Atmosphere with a Given Distribution of Relative Humidity”, the work was the first to represent the fundamental elements of the Earth’s climate in a computer model, and to explore what doubling carbon dioxide (CO2) would do to global temperature."

With all the alternate energies, I read about plenty of 'gunners' - we're going to achieve xxxxxx by xxxxx - but I don't see many (any) 'goals' being achieved.

There are also plenty of cost blowouts and time extensions.

IMHO things just don't appear to advancing too well......................... if at all!

USD$76 Billion in just one place has not done what some would have had you believe it would have.

Copy of thread is just posted

Not suggesting Solar, wind, hydro are bad. Just noting Hundreds of billions invested in Solar, wind and hydro power have done little to assure 100% 24/7 required power security in Several countries who are only just finding out Nuclear is not optional..

The video does not match the headline.
The video is a puff job for solar.
The problem as always is storage as the "Duck Curve" looms large.IE solar produces energy when few want it.
The cost of battery storage is still exorbitant despite the pretty pictures.
Tonopah should have taught the Californians something.

I watched just a bit and noted the numbers and the ongoing current issues in California and similar places which assumed rather than proved money well spent. Missed the puff job part sorry. If it was they clearly have egg on their faces! [bighmmm]

Not fully agreeing solar produces at the wrong time. It just doesn't produce all the time as always needed.

Solar has its place. Its is not the only part needed was and is my view. There is a puff job on Solar in the paper today. It is both true and missing the part which is capacity at worst possible times is not always possible with part time options. The big battery brigade are really a tiny minnow in terms of the worst of circumstances.

Just to illustrate the duck curve here is a "fairies at the bottom of the garden "video from the US Department of Energy.
They don't discuss how energy use can be curtailed at night except by pricing poor people out of the market.
They do not discuss the price of storage.
All glip crap to me.

Over and under supply occur with coal as well? One of the cool part for retail is a constant Over priced amount we pay.

Many of us use off Peak for hot water and some of us use electric pre heating or pre cooling.

Storage of significant excess is not yet here. A few places it is being installed OS right now to use cheap power times even in places with power shortages at other times. Not suggesting BIG lithum are much more than a match stick size and will never be grid scale at a scale we require.

Spare or dedicated Wind, Solar and Nuclear to hydrogen/ammonia or desalination when excess power is available are all on the cards I think.

The Ammonia / nitrogen side is critical to food security I think myself.
