Hello Rob!
** On Sunday 10.05.26 - 15:16, you wrote to me:
I thought Spain and the Netherlands seemed to be doing well with them.
I just remembered reading about a country that had built hundreds
of them along the coast and the expense of operation was so high
and the output so low that they were cursing the idea..
I asked chatgpt about that:
"
There isn't a single country that broadly "built hundreds of wind turbines along the coast and now regrets it." That claim usually comes from political debate or local backlash rather than a national reversal.
A few countries are often cited:
* Denmark pioneered offshore wind and still strongly supports it overall, even though some older projects were retired or criticized over cost and maintenance. ([Wikipedia][1])
* Germany and the United Kingdom have faced complaints about visual impact, wildlife concerns, costs, and grid issues, but both continue expanding offshore wind rather than abandoning it. ([arXiv][2])
* Australia has seen growing local opposition to proposed offshore projects in places like Victoria and New South Wales, with some projects delayed or canceled. ([ABC News][3])
* Sweden rejected several offshore wind proposals partly over military radar concerns, not because existing turbines failed. ([Business Insider][4])
So the more accurate picture is:
* some coastal wind projects have faced backlash, delays, or cancellations,
* but no major country has generally concluded "offshore wind was a mistake" and dismantled hundreds of turbines because of regret.

We'd have to look up the current situation but the notes that I
took at the time (about 2006) talked a lot about how harmful
they were to people or animals living near them and how the
power output was 'dirty' with high frequency spikes that damage
the power systems and they bleed bleed power into the ground
affecting humans and animals..
Also, some truth to all that, but there are mixed ideas/evidence:
"
Claims like that circulated heavily in the 2000s, especially around 2005- 2010, but most of the more dramatic allegations were either unproven, exaggerated, or based on misunderstandings of electrical engineering.
There *were* several categories of concern around wind turbines:
### Health complaints ("wind turbine syndrome")
Some residents near turbines reported:
* sleep disturbance
* headaches
* stress/anxiety
* annoyance from noise or shadow flicker
The controversial idea called "wind turbine syndrome" was promoted by physician Nina Pierpont. However, major public health reviews in countries like Canada, Australia, and United States generally concluded there was insufficient evidence for a unique physiological disease caused directly by turbine emissions or infrasound.
That said, noise annoyance and stress effects are considered real for some nearby residents, especially when turbines are placed too close to homes.
### Animal impacts
These concerns are much more grounded:
* birds and bats can be killed by turbine blades
* offshore wind can affect marine ecosystems during construction
* habitat fragmentation can occur
Modern turbine siting tries to reduce this:
* radar shutdown systems for bird migrations
* avoiding major flyways
* slower blade speeds in high bat activity periods
### "Dirty power" and high-frequency spikes
This part mixes some real engineering issues with exaggerated claims.
Wind turbines use:
* power electronics
* inverters
* switching systems
Those can generate:
* harmonics
* electromagnetic interference
* transient voltage spikes
These are real electrical phenomena, but utilities routinely deal with them using:
* filters
* grounding systems
* grid synchronization equipment
* harmonic correction
The claim that turbines broadly "bleed power into the ground" causing widespread illness in humans or livestock is not supported by mainstream electrical engineering evidence.
There *have* been isolated grounding faults or stray voltage problems around specific installations - similar to problems that can occur near substations, farms, rail systems, or industrial equipment - but not evidence of a universal turbine effect harming nearby populations.
### Why the stories became widespread
Around 2006-2012 there was a large backlash movement against wind farms in several countries:
* United Kingdom
* Canada
* Australia
* United States
The debate mixed:
* legitimate local concerns
* early-generation turbine problems
* anti-renewable political campaigns
* internet amplification
* misunderstanding of electrical terminology
Early wind installations were also noisier and less refined than modern designs, which added to the controversy.
"
So.. early turbines designs were not so great (noisy). It's not so good news that the turbines mess with bat sonar.
Also, as I mentioned about ouput, a number of countries built
enough turbines to supply 30% of their power (at full output)
but in use found they virtually never even got close to that.
[...]
As I said, this information is not right up to date, much of
it coming from an article called A Problem with Wind Power
written by Science editor Eric Rosenbloom (Vermont) in 2006..
So maybe they have found ways to improve things since then.
Yep.. still not a very efficient system.
