The endless wind drought crippling renewables

The spectre of power failure is haunting Europe as Britain and Germany demonstrate that modern societies can’t run on wind and solar power. Wind droughts are the fatal flaw in the system and one can envisage a future book titled How Wind Droughts Destroyed Western Civilisation. Think about the consequences of a system blackout if Net Zero policies are pursued to the bitter end in Western Europe and Australia…

Texas in 2021 gave us a glimpse of the abyss during a spell of low wind and a serious cold snap. Hundreds died and it would have been thousands if the state had gone completely black, instead of hanging on by a thread. Now, Texas is planning to subsidise gas producers to maintain capacity in the face of competition from subsidised wind and solar power.

Don’t laugh, this was happening here with a deal in Victoria to maintain the supply of coal power from Loy Yang A to the Portland aluminium smelter. However, plans are now in motion to close Loy Yang B ahead of schedule with things looking increasingly grim for the smelter. Both the major parties in NSW promised before the recent election to keep the coal fires burning at Eraring.

Wind droughts were not properly considered in the rush to decarbonise the power supply, but they can’t be ignored any longer. The burning question is: How did the meteorologists fail to issue wind drought warnings? They monitor every other kind of extreme weather to feed the inexhaustible appetite of the media for bad news about ‘climate change’.

In Australia the answer is easy. According to a CSIRO report in 2002, the Bureau of Meteorology used the average velocity of the wind for weeks and months to measure wind resources with information collected at hundreds of sites established by the BOM during the 1990s. Tom Quirk and Paul Miskelly first reported wind droughts using the AEMO data which reports the output from the registered wind farms at five-minute intervals.

Our wind droughts mostly last less than a day and they max out around three days, based on the AEMO records. In the BOM records, a wind drought lasting three days would simply lower the number for the week or the month without signalling that there was a serious restriction in the supply.

The neglect of wind droughts in Europe is harder to explain because the Dunkelflaute or ‘dark doldrums’ (the still, dark periods), can persist for weeks. They must have been well-known to sailors for centuries, also to the millers who pumped water in Holland and those who milled grain across the continent. And what about the experience of recreational sailors in modern times? In the absence of readily available historical records, it was helpful to read this comment by ‘Michael’ on a recent post by my colleague Peter Smith. It is an extract from a 1901 book by H.G. Wells.

‘Wind was extremely inconvenient for the purpose of pumping [water from mines] because in these latitudes it is inconstant: it was costly, too, because “at any time the labourers might be obliged to sit at the pit’s mouth for weeks together whistling for a gale”.H.G. Wells, in Anticipations of the Reactions of Mechanical and Scientific Progress upon Human Life and Thought, 1901.’

Yes Virginia, they did have wind droughts in England before 2020!

Official recognition in the wind industry was slow in coming, although the German policy of energiewende was clearly in trouble in 2018 when a government report admitted that it was failing on three vital metrics: cost, reliability, and emission reduction. Recently, there has been more coverage of wind issues, but officially the green transition is still happening. More research is required, with hard questions directed to the responsible authorities.

Lazard's levelised cost of power generation figures remain "highly implausible"

Net Zero Watch has slammed new estimates of the cost of electricity generation published by the merchant bank Lazard.

Lazard's Levelised Cost of Generation report appears annually, and is widely cited, supposedly as an authoritative source. However, its credibility must now be in serious doubt, because of the divergence of its underlying assumptions from reality.

Net Zero Watch's criticism centres on the cost of offshore wind, an area in which it has considerable expertise, and where highly transparent UK data make firm conclusions possible.

Net Zero Watch's deputy director, Andrew Montford, explained:

"Lazard's estimates of lifetime output are probably overstated by more than 50%, and their estimate of operational expenditure by more than 200%. Their figures are highly implausible."

Australian EV drivers will soon benefit from nation-wide fast charging program

This is amusing. It's like a dog chasing its tail. It never catches up. The facility will entice more people to go electric, which will heighten the chance that when you roll up to recharge there will always be someone there recharging ahead of you. Frequently spending hours waiting to refuel will not tbe attractive. Electric cars are ok as suburban runabouts but are a pain for long trips

Electric car owners will be able to drive from Adelaide to Alice Springs, cross the Nullarbor, and run from Tasmania to Far North Queensland without stressing about charging, thanks to a new network coming to Australian roads.

A Federally funded program working with the NRMA to put 117 fast chargers on Australian highways will bring an end to “range anxiety”, according to Minister for Climate Change and Energy Chris Bowen.

“EVs aren’t just for the cities, and Australians who drive long distances either for work or for holidays should be able to reap the benefits of cars that are cheaper and cleaner to run,” he said.

“We’re making range anxiety a thing of the past. This project will help close the gaps and known black spots in the network and make it possible to drive from Darwin to Perth, Broken Hill to Adelaide, and from Brisbane to Tennant Creek in the NT.

“This national rollout will help put more Australians in the driver’s seat of cheaper and cleaner cars.”

The Federal Government’s “Driving the Nation” fund will spend $39.3 million ensuring electric car chargers are placed at 150 kilometre intervals on national highways.

Full technical details – including the charging speed of the network – have not been released.

The NRMA will be using purpose built charger models for various public charging locations depending upon environmental conditions, location and power availability, sourcing chargers from manufacturers including Tritium, Kempower and ABB.

A spokesman for the organisation said plug power for the public charging locations “will initially range from 75kW to around 300kW”.

The fastest chargers currently used in Australia can add around 300 kilometres of range in about 20 minutes to high-end electric cars with more than 500 kilometres of range.

Cheaper models such as the Nissan Leaf, that can’t handle the flow of energy at need about an hour to add around 200 kilometres of range.

Mr Bowen drives a Tesla Model 3 – Australia’s most popular electric car.

Priced from about $64,000 drive-away, the Tesla offers around 491 kilometres of driving range.

Tesla has a widespread “Supercharger” network that is not available to owners of other electric cars.

Carly Irving-Dolan, NRMA chief executive for energy and infrastructure, said the network would be the charging backbone of Australia.

“The NRMA is excited to be partnering with the Australian Government to grow our regional network of fast charging stations across the country because we fundamentally believe that regional Australia should not be left behind,” she said.

“Australia’s expansive landscape presents some unique and local challenges to ensure that we are ready for more electric vehicles on our roads.

“NRMA has over 100 years’ experience helping Australia address transport challenges and we are committed to building on this work through this national charging network.”
