[#2596716]

They seem to be the Marmite of structures. Not that they're darkly coloured and utterly vile, but that they seem to totally polarise opinion.

I went for a ride through the scout moor wind turbines last night. Here
(and on the cover of this months mag):

It was quite surreal really. They remind me of a sort of benign version of War of the Worlds. They're impressively huge when you're up close. I really like them. I think they even add to the scenery in some way. And obviously they're doing something a bit useful.

So... love 'em or hate 'em? and why?

Love, because we need more of them. It seems redundant for us to comply with ugly tarmac all over the landscape then winge at a few turbines!

When I own my own place I'm slapping solar panels and turbines all over that badboy :mrgreen:

I don't mind them but I wouldn't want to see them on every visit into the countryside.

I like them, then again I like engineering on a grand scale. It's all the not I'm my back garden brigade that get on my t##s.

Love? No. Hate? No. Tolerate? Yes.

Wind turbines aren't too bad visually. They're certainly not the worst things we've polluted the landscape with.

I've never seen a single man-made thing that even comes close to being comparable with what nature had preceeded it with.

Hate them, mainly because they're bloody useless.

Those who actually know about and have objectively studied these things know that they're a waste of time, money and resources. We'll be ripping them out within 10 years.

Probably not worth it - especially the turbines, but I appreciate your sentiment.

Backhander, are they not paid for and installed by private companies?

The government (this one, last one, one before that etc, etc) have already decided that we're having nuclear.

These things are just a sop, something to ease our consciences & make us think they are actually taking renewable energy seriously.

backhander - read your references:

"rooftop wind turbines"

not bigger turbines. Those who actually know about these things can tell the difference between them. 🙄

I don't mind them, but the landscape does look better without them.

I like the idea of industrial units/estates having their own wind turbine systems where it is worthwhile doing.
There's a massive Nike building in Belgium with several wind turbines and Wood Green Animal Shelter near Godmanchester has it's own wind turbine. Smaller scale stuff like that providing 'local' power seems like a good way forward.

1/10 on rate my troll backhander please try harder

from your own link

Non-technical readers should be aware that the findings of this report apply only to currently available models of building-mounted wind turbines, designed for connection to the national grid. As anyone who knows anything about wind power will attest, urban environments and building mounting is probably the most challenging context in which to try to make wind power work, and the findings of this study cannot be generalised to larger-scale wind, nor to freestanding wind of any size mounted on poles or masts well away from obstructions. All the evidence (and theory) is that wind power is an excellent and highly effective choice for such conditions, which exist widely across the UK away from buildings and towns.

The title was wind turbines, are you suggesting that rooftops are not wind turbines
I have recently looked a 2 off 30 meter masts located in the south west. Combined, these at peak load supply 12kW/day or 0.5kW/hour, . That'll do a couple of laptops however most days it's a fraction of this. Whats the production ratio on WTs; 13-26%? Its just greenwashing, the way that these things are being marketed and sold is a disgrace.
Edit; flowerboy, wind your neck in.

I like them too. The Scout Moor installation provides power for about 45,000 homes which is damn fine.

I like...although if you've ever played Simcity 2000 you realise you need an awful lot of them on the map before they match one nuclear power station 😉

Backhander - do you have any comparable figures for the big buggers like the ones on Scout moor. I've genuinely no idea.

Incidentally, they were all still last night. Not a breath of wind. That is very very unusual for up there though

Whats better a widturbine that doesnt pollute, and can be recycled, or a large nuclear pile of scrap, protected by armed police 24 hrs a day for ever, that we dont know how to recycle, or even keep safe for the next generation.

Bit like a chav neighbour,(nuclear power that is) as long as you keep throwing money at them, and having the police call round theyre happy, until theres a big bang.

13-26% of the wind which is free, so something for nothing. You are not talking about a 26% efficient engine that only gets 26$% of the energy from a litre of finite resources here - you are talking about efficiencies from FREE renewable resources.

Wind turbines are not free, the opposite in fact. Flowerboys is just jumping on a subject he knows nothing about (just like rugby) because I'm posting. Rustynail has it correct, they are a plaster for a sucking chest wound.

http://www.wind-watch.org/documents/eon-netz-wind-report-2005/

Even EON who have installed quite a few are aware of the poor performance of WTs.

I love watching them - it's somehow calming to sit on a wall mid ride and watch them.

However as a genuinely useful energy source they are a little dubious. They are simply too inconsistent in energy generation and only produce about 30% of the claimed output in reality. If the huge grants and subsidies didn't support them and their erection wasn't forced on energy companies to meet imposed quotas I doubt they would be viable.

so far all you've contributed is a link that doesnt back you up in anyway and a couple of other dodgy looking links, could you provide any properly backed up facts?

I think that the E-ON wind energy report 2005 is about as respectable as you'll get.

Presumably you mean 12kWh per day or an average of 0.5kW - but I am not sure. Get it right.

I like 'em, not that ugly, supposedly helping with the environment etc.

But the cynical side of me worries that:
They don't provide much electricity
they aren't that green
During their life cycle they aren't even carbon neutral nevermind carbon reducing
They are being put up by private companies with massive grants from the government (ie it's a money earner not an earth saver)
The infrastructure implemented to build the things probably harms the environment more than it helps.

No stats to back any of this up, it's just my cynical expectations

I love them.

In fact, I have one on my hat which powers the windscreen wipers on my sunglasses.

They go really fast, especially when I ride down a steep hill!

I think you'll find that kW=kWh. The hour was put in for those who may not know, get it right.

I always find it funny that some people object so strongly to wind turbines and don't bat an eyelid about the single ugliest construction ever to scar our landscapes, the electricity pylon. I guess they've "always been there" though.

the E-ON paper references data from 2004 in a limited region of Germany. Therefore, it is limited in value due to date and geography.

Wind turbines are not perfect and are generally more efficient in production when sited offshore. The bigger the turbine the more efficient it is (laws of physics here kids) and the siting of them is all important.

They are part of an answer to a problem we've not yet solved - most of our power comes from finite resources that are becoming more expensive and the consumption of them pollutes and warms the environment. We will need a blend of generation techniques to provide enough energy for the future - especially as we go further towards a total electric requirement.

problem is you need a LOT of them to produce meaningful amounts of energy, which means lots of factories, materials, energy used in production etc.

I bet the energy payback time for a windturbine is massive. Not saying that they aren't good for some situations, but I don't think you can just blanket the land in them and expect our energy woes to disappear.

I think we need to stop using more energy to start with. Do we really need street lights all over the place at night? On motorways at 3am in the morning??
Industrial estates where all the buildings are left illuminated overnight, no doubt with 10's if not 100's of PCs using power unnecessarily, electronics on standby in millions of homes....everyone says, but it's only a few watts (for their household), but multiply that by every household in the UK & it starts to mean something....

what the one with the massive caveat which I quoted that is only about home mounted wind turbines...... you really do need to try harder.
which says

I absolutely agree with this, I just don't think that wind is going to provide an amount of energy which will make a difference. There are currently some very interesting developments with wave/tidal technologies (the anaconda). I'm certainly not anti renewable but there is an awful amount of greenwashing going on.

Not that work effectively. Although I do believe we need to pursue them much faster and further. Then again, the environmental impact of a Severn Estuary tidal system would have been massive.

greenwashing
😆

“In 2004 two major German studies investigated the size of contribution that wind farms make towards guaranteed capacity. Both studies separately came to virtually identical conclusions, that wind energy currently contributes to the secure production capacity of the system, by providing 8% of its installed capacity.

isnt that just a long winded 😯 way of saying the wind doent always blow?

Binners - I'm currently waiting for the patent to go through.

My plan was to ask Funky Duncy Bannatyne the Dragon for 6 billion dollars to get my company off the ground. I've got a sneaking suspicion that he and Theodopopopolous Paphitis the Dragon will come to fisticuffs in order to give me the cash.

They aren't the same though??

watt = energy per second, 1W = 1 j/s.
1Wh = energy used by a one watt load in an hour, 1Wh = 1*3600 = 3600 j.

Or something like that......

Arf arf 🙂

No, that's why these things tend to get turned off nowadays.

Although street lighting is quite important in towns. Walking home from the pub in pitch darkness could be fun and games. Esp if you're female say and alone. You wanna carry a torch around with you at all times?
