Bazz, in answer to your question on subsidies to windfarms. The only one that I have knowledge of with any certainty is the Coopers Gap one in SE Queensland. Over130 turbines. The State Government subsidy for the 20 years of the complex is $200,000 to the complex owners per year per turbine. The property owners on who's land the turbine sits receive ~$20,000/per turbine per year for the life of the facility.
At that point, the landowner has the responsibility of decommissioning, deconstructing and remediating the site to original condition. Estimated cost for this is ~$100,000.
This subsidy is regardless of whether the turbine produces 100% of plated output, or draws from the grid to keep the blades turning.

Has been, I was brought up in the UK ( now have lived in Oz more years than I spent there) and we all talked about the Gravy Boat factor. Since arrival in Oz, I have progressively adjusted my few on it...

First the gravy boat (1990)
Second the Gravy Train ( 2000)
Third the Gravy tanker (2010)
Fourth the Gravy Cruise liner (2016)
Now its the Gravy swamp ( 2020)

Who knows how big it will get.. BUT, the bigger it gets, the sicker and weaker Western Civilisation becomes and WILL go the way of previous dynasties such as Inca, Rome, Greece, Octomom, Brit Empire...

Re Jay Cee Ess

Check out the second scandalous subsidy scheme promoted by BOJO, in of all places N, Ireland. The first led to the suspension of their Gov Assembly for 3 years and this may do the same. Effectively a single wind farm gets 375,000 GBP for delivering 51,000GBP electricity to the grid. Wish I could get that return from my Superfund!

The Gravy Train is the ballot box for the Progressives !

Thanks JCE, on that example it is worse than I imagined.
I notice the land holder is responsible for the removal.
I think $100K would barely be enough.
Then after it is collected together who receives the rubbish ?
I did read somewhere that they bury the blades, hmmm.
That suggests they are fibreglass, not aluminium or other metal.
Another thread is worrying about waste it can now start worrying about
end of life wind turbines.
I wonder if the cleanup includes removing the concrete base.
That will cost big money on its own.
It might be that the economics of it all means the land will have
zero value and will be a burden on the descendants of the farmer

Bazz, you are stepping into the zone that no-one wants to face. There are no standards set for the remediation of the base. As you're probably aware, it is a great lump of steel reinforced concrete going down three or four metres the size of a suburban house. One suggested strategy is to simply trim off the top level and bury it under about a metre of dirt.
I'm not 100% sure on these blades, but one standard is actually balsa wood sheathed in resin reinforced glass fibre. No hope of recovery and reuse. Depending upon location, it is unlikely that many blades will last the 20 years thanks to leading edge erosion and UV degradation of the resins. (Australia isn't Europe for UV levels.) These blades had a transport quoted weight of 22 tonnes each.
Several farmers in this project have ten (or more) turbines on their properties. There is no incentive to continue to farm and pro-actively manage their land with that income stream. Trying to sell in 15 years time means that the future responsibility for the turbines will destroy many prospective buyers interest.
I'll save a killer comment on this project for later.

Which raises a real problem;
Due to the almost total belief that wind and solar are the only way
to go for future electricity then expansion of windfarm numbers is
a given and in twenty years time after it has become obvious that
the "renewables" are not economic or renewable we will have lost a
lot of farming land for nothing.
It really is time for a ban on windfarms.
