Professor emeritus Ivan Kennedy, faculty of science at Sydney University, tells me he has been doing some work on the effect of turbulence engendered by wind turbines. Among other things, he hypothesizes that this may have a drying effect extending beyond the immediate area. The outcomes: a fall in the productivity of arable land and more water vapour in the atmosphere.
You’ll note, I said, he hypothesizes. Importantly, he also points out that his theory is testable using technology such as ground-based sensors and satellites. Being a scientist of the old school, he doesn’t rush to conclusions even provisional ones. Greenies are not nearly so constrained; operating comfortably in fact-free zones.
As an exercise, let me take each of the two hypothesized outcomes in turn and see where they lead. You will see that they lead realists (putting modesty aside) like us, and greenies in diametrically opposite directions.
Let us suppose there is a measurable fall in the moisture in agricultural land surrounding wind farms. Our take: build fewer wind turbines near agricultural land. (Build none at all actually but you get my drift.) Their take: climate change is causing droughts. Build more turbines.
Water vapour is by far the dominant greenhouse gas. Suppose it is found that the uplift of water vapour is greater, the nearer are turbines to bodies of water; those, particularly, in seas or close to irrigated areas. Our take: build fewer turbines close to water. Theirs, CO2 is causing the oceans to warm. Hence more water vapour. Build more turbines.
The bitter or delicious irony, depending where you stand, is that the more deleterious effects turbines have on the natural world, the more must be built to counter such effects. Wind turbines, and solar panels too, are bulletproof. They both make lots of money for powerful people and big businesses and, not least, for China. And they appeal to the gullible; who, at whatever cost to reason and the public purse, see them combatting the imminent imaginary climate Armageddon.
Even despoiling landscapes and seascapes hardly rates a mention now that Prince Phillip is not around to express his displeasure in his own blunt way. In case you've missed it, Prince Charles is not a chip of the old block. Mind you, that aside, alarms have been raised about the enormous quantity of materials and energy required for the manufacture of turbines and solar panels; for their use of rare earths; their relatively short life spans; and the problem of their disposal. Really? Among whom?
OK, only among those who deal in facts. In other words, not among the much vaster number of people, including government ministers and their apparatchiks throughout the Western world, who deal in fancies. Among the minority who deal in facts is Mark Mills, senior fellow at the Manhattan Institute. If you haven’t already, it is well worth while keying in to his presentation on February 9, 2021 to the U.S. House Energy Subcommittee on Environment and Climate Change. Here’s just a taste:
- Building a single 100-MW wind farm requires some 30,000 tons of iron ore and 50,000 tons of concrete, as well as 900 tons of nonrecyclable plastics for the huge blades.
- A storage system to back-up such a wind farm would require using at least 10,000 tons of Tesla-class batteries.
- The tonnage in cement, steel, and glass is 150% greater for solar than for wind, for the same energy output.
- Under the scenarios for clean energy imagined by the World Bank, the 700 tons of neodymium currently mined would need to increase by between 1,000 and 4,000 percent. Indium by as much as 8000%. Cobalt by 300 to 800%. Lithium by more than 2,000%.
- The Institute for Sustainable Futures at the University of Technology Sydney, concluded last year that the supply of elements such as nickel, dysprosium, and tellurium will need to increase by 200 to 600%.
As Mills explains, while the minerals required are there, digging them up will be daunting and pricey. Count among the costs: environmental degradation; increased threats to the West’s national security in view of China’s dominance in many of the supply chains; the use of child labour in countries not so sensitive to human rights; the massive amounts of energy required to mine, transport and process these exotic minerals; and, the bottom line, the demise of reliable and affordable hydrocarbon power.
On hearing all of this, the Democrat members of the subcommittee, including the chairman Paul Tonko (NY), recanted and became RE-skeptics overnight. I’m fabulising. Inconvenient facts don’t impact dullards or zealots.
Prof. Kennedy’s hypothesis might be true. So what? It would just sit atop of the existing enormous pile of inconvenient facts. Rafe Champion, another friend fond of facts, continually pesters Australian politicians, all 837 of them in this over-governed land, about the inconstancy of wind. No wind no power, he says. Follow up tricky question: if it takes 1,000 turbines to power a particular town when the wind is blowing, how many turbines does it take when the wind isn’t blowing? Alas, arithmetic isn’t the strong suit of the political class; except, that is, when counting prospective votes.
It took exquisite torture on the part of O’Brien to convince Winston Smith that two plus two equals five. Childs play for greenies. To wit, when the wind stops blowing a big battery can take over, they claim, with the conviction of megalomaniacs.
One of the biggest lithium battery installations in the world at Hornsdale in South Australia can reportedly deliver 194 MW for an hour. Though electricity usage has spiked above 4,000MW, South Australia (pop. 1.8 million) generally uses from 1,000MW to 2,500MW depending on the time of day and season. Ergo, the battery would generally run out in 12 to 5 minutes if required to take over.
Mind you, as deluded as they are, look at us. We persist in using logic, facts and figures. Might as well babble for all the influence we have. And then again, what else is there to do? We are condemned, Sisyphus-like, to make the same arguments over and over again. Captors, as we are, of reality.
The one saving: real life is our pal. As the paranoid delusions and lies increasingly hit the road they’ll be undone. For example, when the wind isn’t blowing and the sun isn’t shining that illustrative town I mentioned will last ten minutes or so on batteries before the lights go out. QED.
