About these pages
A good argument will be backed-up with evidence and anyone who uses any argument should be able to provide sound evidence in support of their stance. Many, probably most, wind power opponents make claims for which they can provide no supporting evidence.
From The Skeptic's Guide: "An ad hominem argument is any that attempts to
counter another's claims or conclusions by attacking the person, rather than
addressing the argument itself."

A typical straw man argument used against wind power is: "No country can run on wind power because the wind doesn't blow all the time. When the wind stops there's no electricity." I doubt that anyone has ever advocated running a country on wind power alone; that would be the only case in which this argument would be valid.
An example: a wind power opponent states that fossil fuels are needed to build a wind farm, therefore his case that wind power does not replace fossil fuels is proven.
For example, it has often been falsely claimed that 'the world is turning away from wind power'. Sometimes those using this argument will cite one or more wind farms that have been abandoned or decommissioned; a wind farm typically has a life of about 25 years, after which it is quite probably superseded by more efficient wind turbines. In fact the amount of wind power worldwide continues to grow by around 20% per year.
An outstanding example of someone getting it totally wrong is the case of a prominent economist who wrote a submission to a parliamentary committee claiming that it would take more than 3000 years for a wind farm to 'pay back' the carbon dioxide emissions resulting from the manufacturing of the concrete used in the turbine's footings. This figure is too high by a factor of about 60,000.
The third example I will give is the claim, used particularly by the opponents of a wind farm on South Australia's Yorke Peninsula, that wind farms are incompatible with agriculture. One of several ways in which this can be refuted is to point out that the three US states with the greatest amount of installed wind power are also the three most agriculturally productive states in that country.
One of the most absurd arguments that wind power opponents use is the claim that wind turbines don't reduce CO2 emissions. The amount of electricity generated in a power grid must always equal the amount being consumed, so when wind turbines put power into a grid other generators, often fossil-fuelled, generate less; so less fossil fuels are burned. I've discussed this subject elsewhere in greater depth. Also, quoting from Scientific American:
"Wind Power Proves Effective CO2 SaverThe piece was written by Paul Brown and dated on October 22, 2013.
One 'argument' you might come across if you point out the science about turbines and health is "So you believe that all those people who have reported to wind farm inquiries about their health problems are telling lies!". Of course this is another non-sequitur; they are drawing an unwarented conclusion. These people are more likely to be mistaken in their belief about the cause of their illnesses rather than lying; although some may well be exaggerating their symptoms.
For example, there has been no increase in backup power in South Australia following the installation of substantial wind power in the years between 2003 and 2016.
Strong evidence that wind power does reduce emissions is given by the graph on the right that shows that emissions fell in SA by 29% since 2002. There were no wind farms in SA in 2002, by 2014 South Australian wind farms were generating about 37% of the state's power. The best emissions reduction performance from any other state was a decline of 8% from NSW.
The graph also shows a significant decline in Victorian emissions starting in 2012. This coincides with a doubling (from 514 to 1066 MW installed) of wind power in that state. The percentage of wind power in Victoria is much smaller than that in SA.
550 MW of installed wind power in Australia can be expected to reduce emissions by around 1.5 million tonnes per annum so it is not enough to explain the full drop in Victoria's emissions, but it would have been a contributing factor.
When a proposed wind farm is opposed by a group of vocal and dishonest
Where there is no dishonest opposition, there is no social disruption.
For example, in my region of South Australia, there was neither social disruption nor dishonest opposition before the building of Clements Gap, Brown Hill Range, Snowtown or Wattle Point wind farms, but there was on Yorke Peninsula when the Ceres Project, which included a big wind farm, was proposed. It was opposed by a very dishonest group calling itself the Heartland Farmers.
In my experience vocal opposition to wind power almost always is accompanied by denial of climate change and ocean acidification.
It would be interesting to know whether the climate science denial follows the opposition to wind power, or the opposition to wind power is at least partly because the disbelief in ACC causes the person to not see so much need for renewable energy. Perhaps one in some cases, the other in other cases?
Below I intend to list a few of the more ridiculous arguments against wind
power that I have had thrown at me (in addition to the examples listed above,
which were all based on arguments that I've heard used).
Ridiculous expectationOn discussing wind farms and health I mentioned that I lived within 15km of a wind farm and that I have slept under turbines many times and have had a good night's sleep every time. The respons was "So what? You should live in a wind farm house for six months."
This argument probably comes from someone hearing that the capacity factor of a wind farm is 30%. What a capacity factor of 30% means is that a wind farm that can generate a maximum of, say, 100 MW will, on average, generate 30 MW. A little thought will then tell us that if it generated power only 30% of the time it would have to be either generating at 100% power or not generating at all; never generating at half power, two-thirds power, a quarter power; plainly absurd.
The graph on the right shows the percentage of the time when total wind farm output in SA exceeds a given percentage of installed capacity. For example, it shows that 10% of the time South Australian wind farms are producing about 55% of installed capacity and 60% of the time they are producing about 18% of installed capacity.
South Australian wind farms are generating power far more often than they are not generating power.
Finally, I should say that the average capacity factor of Australian wind
farms is closer to 35% than 30%; excellent by world standards.
Wind power alone; energy storageA wind turbine opponent on Facebook, May 2016: "Ask yourself this. If you were on a life support machine how would you like it to be powered?"
Implying, on no basis whatsoever, that if there is wind power there cannot be any other sort of power. I pointed out that in the real world wind could be combined with solar PV, solar thermal, biofuels, hydro and there could be energy storage. The opponent went on to say: "There is no viable storage and probably never will be. All research so far shows it would be massively expensive and would need fossil fuels to be built."
The fact that it would require fossil fuels to be built is, of course, quite irrelevant. I remarked that Wikipedia says that worldwide in pumped hydro alone there is capacity for 127GW (that is 127,000,000,000 Watts) of power and 740TWh (that is 740,000,000,000,000Wh) of energy in storage.
Not to be put off, the opponent went on to say: "There is no viable storage for industrial wind energy."
