A SUMMER OLD FARTS REMEMBER?



And mans carbon footprint didnt set it all up.

Back in the village, no not the 'of the  damned one', another one  a bit out of town, after a month on the road in the off shore Island to the North where it rained on around 30 of the 34 days. Blenheim on the 30th, Parnassus for new year then home,  finally some awesome heat that seemed to be every summers day in the middle of last century

Washing dry before the next load washed, some R & R then up to the Gorge for a few days, maybe an unlucky salmon that thought it had escaped the trawlers off the Rakaia Mouth.

So not many, if any of the thousands of Houses sold to a duped public as helping the homeless but in fact a government subsidised Lottery only open to rich pricks already on their way.  No noticeable extra trees of the millions programmed, but the plebs will never know.  A decade high road toll in response to the other SLG suggesting zero as a target, then today Dr Wood (n't) ever understand, a mind blowing policy to "Build" four and a half "wind farms a year".

Currently there are 17 operating, in NZ and they include some very small operators,  so somehow that will increase by 25% annually.
How many have visited these bird killers. like bag pipes, in small numbers at long distance they have a certain sculptural serenity as evidenced with the easily seen from SH2,  the 700 ha Tarrarua wind farm south of the Manawatu Gorge. One of the largest in the nation with around a hundred 660 KW towers and another 30 rated at 3 MW, total less than 600 MW.
To the north of that site lies the Te Apiti on 1100 Ha  with a "nameplate capacity of 90 MW.
West of the Capital is another large scale generator with a "nameplate capacity" ( doesn't that sound bigly) of 140 MW.
These three are situated on very sparsely occupied farm land and of only visual impact to the citizens, no noise, vibration or other drone like annoyance

Genesis are looking at two similarly remote options east of Ekatahuna.

FOUR and a Half a year how long before the snowflakes will be asked to endure something not every  one sees as beautiful additions to a landscape much closer to their bit of paradise.
Many residential developments have fallen foul to nimbys around Banks Peninsula where if it is not for me then no one else will enjoy such crass pollution of "landscapes, suddenly cast into public guardianship way beyond rights conferred by ownership in fee simple.
Thousands of Hectares per year, millions of dollars, and afaik there is little enthusiasm if no cross subsidy or direct government dosh enters the equations.
Then of course the never mentioned fact (hence the nameplate bit),  sometimes the wind don't blow or as has occurred a couple of times in South Australia it blows too hard and that can coincide with heightened demand!

However the good Dr after gutting the Naki Oil and Gas industry on a whim of the appointed PM, is now embarking on an equally flawed virtue signalling exercise to do something akin to pushing water up a slope with a rake(it matters little which way up if you are asking).
Here is a thought Megs, if it is such a great Idea why isn't the market flooded now with investors, oh thats right maybe it aint such a great idea for people using their own money.

But it is summer and some great weather so seasons greetings to all, in particular my host colleagues,
The commenters who challenge the content, and also the others.
As Moi embarks on the second half of a seventh decade my troubles seem insignificant to those that afflict less fortunate. and though just getting through gets harder, I am enjoying a certain Cest la vie ambience around a well performing National Cricket team, the weather, love and respect of friends and family along with time to enjoy the good bits.

Thank goodness for the last paragraph Dodger, I thought we had lost you to the dark side..... Happy new Year to you and in the spirit of the year to come I challenge your "Bird Killing" remark.

"Wind turbines kill between 214,000 and 368,000 birds annually — a small fraction compared with the estimated 6.8 million fatalities from collisions with cell and radio towers and the 1.4 billion to 3.7 billion deaths from cats, according to the peer-reviewed study by two federal scientists and the environmental consulting firm West Inc."

Well somebody has to count them?

From The Daily Telegraph.. Dontmention France unfortunately

The analysis of almost 3,000 onshore wind turbines — the biggest study of its kind —warns that they will continue to generate electricity effectively for just 12 to 15 years.

The wind energy industry and the Government base all their calculations on turbines enjoying a lifespan of 20 to 25 years.

The study estimates that routine wear and tear will more than double the cost of electricity being produced by wind farms in the next decade.

Older turbines will need to be replaced more quickly than the industry estimates while many more will need to be built onshore if the Government is to meet renewable energy targets by 2020.

The extra cost is likely to be passed on to households, which already pay about £1 billion a year in a consumer subsidy that is added to electricity bills.

The report concludes that a wind turbine will typically generate more than twice as much electricity in its first year than when it is 15 years old.

The report’s author, Prof Gordon Hughes, an economist at Edinburgh University and a former energy adviser to the World Bank, discovered that the “load factor” — the efficiency rating of a turbine based on the percentage of electricity it actually produces compared with its theoretical maximum — is reduced from 24 per cent in the first 12 months of operation to just 11 per cent after 15 years.

The decline in the output of offshore wind farms, based on a study of Danish wind farms, appears even more dramatic. The load factor for turbines built on platforms in the sea is reduced from 39 per cent to 15 per cent after 10 years.

No links I see Wiggo, just hearsay from an unknown source. As you have been caught out making stuff up before I'm surprised at you.

Told you before that turbines and their bearings in any form are under stress whether they be the massive hydro electric or the bearings in your washing machine.

Just changed the bearings in my 15 year old AEG washing machine and now it is as good as new but not a job for the faint hearted.

There is a built in cost for replacing turbines, not the masts or the blades. There are industries that will take the turbine wack in new bearings and anything else needed to bring it up to spec and ready for lifting onto another mast.

Offshore wind farms are more probematic....maybe that was not such a good idea



Lord Egbut Nobacon said...

Just read Prof Hughs paper..and here is the rebuttal.... https://theecologist.org/2014/jan/03/wind-turbines-going-strong-20-years

Neither of these academics mention the word "bearings" once nor do they mention what the failures are. The word turbine replacement is conspicuous by it's absence.

Quite simply Wiggo your beloved coalfired power stations depend entirely on the bearings of the generating turbine and they will need to be replaced after a set time.

Some people say it was the wheel that man's greatest invention and others say it was the screw thread...I say it was the ball bearing race.

Well, I'm no fancy-pants economist, but it seems to me the reason for that is that you're not going to invest in technology with lower environmental costs if your investment doesn't have to cover those costs. As long as we allow environmental costs to be passed on to future generations, there's minimal to non-existent incentive to invest in reducing environmental costs.

Put more simply: if the environmental costs of fossil-fuel power generation had to be borne by investors, those investors would have fled the fossil-fuel market long ago and instead be piling money into more sustainable alternatives (eg wind farms). But as it stands now, why would they give a shit about sustainable alternatives? That's why Megan Woods is right and you're wrong. Your "after us, the deluge" approach is not going to be treated kindly by future historians.

"Well, I'm no fancy-pants economist, but it seems to me the reason for that is that you're not going to invest in technology with lower environmental costs if your investment doesn't have to cover those costs"

But how do you quantify "environmental costs" PM - they are of course usually over stated for political reasons

The reality of wind farms is that they by necessity are usually situated in places that are envireonmentally harsh for machinery and are high maintenance

"Some people say it was the wheel that man's greatest invention and others say it was the screw thread...I say it was the ball bearing race."

Except for the fact that the main bearings of large turbines are Babbit Bearings or were back in the day I worked with them- cheaper, easier to maintain and more reliable than roller bearings in that application

Andrie.....Suddenly you are a wind turbine expert??,,but I thank you 'cos I would never have found this.... https://www.windpowerengineering.com/mechanical/understanding-root-causes-axial-cracking-wind-turbine-gearbox-bearings/

It is developing industry and like the development of the steam locomotive a few things must blow up first. Tell me where they use Babbit bearings? Rotor shaft? Gearbox? turbine? Turbine shaft? or all four?

Andrei said...

".Suddenly you are a wind turbine expert??"

No I am not Egbut - in my misspent youth I worked with large Marine Steam turbines and part of the requirements for earning "my ticket" was understanding of bearings on these and though now long forgotten for the most part was why Babbitt bearings were preferred over roller bearings in this application

And you found the link about catastrophic failures in gearbox bearings used in wind turbine applications. Babbitt Bearings if maintained don't fail catastrophocally but wear predictably and a relatively simple to replace - a job I have been involved in more than once (though not on turbines) as a "boy" holding heating torches, pouring metal and doing what I was told by the older and wiser.

I made an assumption that wind turbine shaft bearing would be Babbitts and now looking it up this is something some designers are belately exploring after catastrophic bearing failures.

One thing that is obvious about this discussion is that each turbine in a nuclear, fossil fuel or hydro power station are producing far more power than any individual turbine in a wind farm and are being continuously monitored so that any potential problem is nipped in the bud so catastrophic failures are generally avoided

If there was ever an exercise to cause a marine engineering apprentice to rethink life's path it would be pouring, scraping and fitting babitt bearings [and unfitting, scraping and refitting the same bearing multiple times]

You could almost have pity on them.

Heading for 41C in Adelaide today, up to the low 50's in the far north and the wind turbines are doing their job. Power is on, and will stay on.

Hey David!!

Mas 22 here today.

Poor bastard, hope you've got plenty of polar fleeces. This heat has the roses looking magnificent and the Barossa winemakers licking their lips in anticipation. I was talking to Charlie Melton the week before Xmas and some of his old vines are looking grand.
