Black Days & Darker Nights: Engineers Spell Out Threat Posed by Increasing Reliance On Wind & Solar

Pin your power supply hopes on sunshine and breezes, and get prepared for mixed results.

South Australians, Californians and Texans know what comes from an overreliance on the unreliables, with plenty of experience of weather-related load shedding and mass blackouts.

Increasing dependence on chaotically intermittent wind and solar is the price we’ve paid for allowing ideology to ride roughshod over sound engineering and solid economics.

Once the engineers were relegated to the back office by wind and solar worshipping ideologues equipped with sociology or arts/law degrees, the end of reliably delivered power at affordable prices was inevitable.

This is the crowd that can’t tell the critical difference between ‘energy’ and ‘power’; that believes the yawning gulf between the promises made by the wind and solar industries and reality can be plugged by a few giant lithium batteries; who berates anybody who mentions sunset and calm weather and renewable energy in a sentence; and who find mathematics, logic and reason all a deathly bore. All the things that engineers are trained to live and breathe, are simply dismissed as old school nonsense.

Well, in Scotland at least, the engineers have finally broken their shackles; they’re on the offensive and they are clearly not happy about where things have landed since ideology was allowed to trump engineering.

Tilting at windmills: Engineers accuse ministers of relying too much on renewables

Scotland’s future electricity supplies are being put at risk due to failures by ministers to fully explore the consequences of relying on renewable energies.

The Energy Strategy Group of The Institution of Engineers in Scotland (IES) says there is a “lack of attention to engineering issues” by Westminster and Holyrood governments, and ambitious targets for achieving net zero electricity supplies to power the nation which have not been clearly thought through.

It warns that thermal power stations are being closed and confidence placed on wind and solar energy without proper safety analysis of their reliability and full consideration of what would happen to the electricity supply when the wind does not blow and the sun does not shine.

The group also says voices which dare to question the rapid switch to renewables or highlight potential risks are often shouted down by a vocal green contingent and branded ‘climate change deniers’.

The result is that a potentially constructive debate which could spotlight problem areas and suggest alternative routes to a lower carbon energy landscape, is being stifled, they say.

The IES Strategy Group insists it is not against renewable energy or the use of wind energy to feed into the National Grid. However, it warns of an urgent need to address the complex technical issues that come with inserting intermittent renewables into the nation’s power supply.

It has called for a national independent multi-disciplinary energy group including people with a range of skills and backgrounds – similar to the UK’s Covid-19 vaccine task force – to coordinate an effective plan for the nation’s future power supply.

A particular concern for the IES is the reliance on renewables to restore power in the event of a total or partial shutdown of the national electricity transmission system. Although rare, such a catastrophic situation affecting a large geographic area would require complex restoration procedures typically involving gas turbines which can operate quickly to restore power.

There are worries that a lack of suitable types of generator for such a difficult ‘black start’ situation could see towns and cities plunged into darkness for several days – raising the possibility of risks to health, and major economic and environment implications.

Iain MacLeod, of the IES, said the Westminster and Holyrood governments’ approaches are “deeply unsatisfactory” but are being replicated around the world as governments embrace renewable alternatives to fossil fuels.

Mr Macleod warned that governments are “allowing the electricity system to become increasingly unreliable”, with decisions based on what appears to be the right thing to do, rather than on reliable evidence.

“On one side we have people who believe that what needs to be done – ramp up renewables – is glaringly obvious and that carrying out studies to show that this is the way forward will hold back progress towards the goal,” he said.

“On the other side are people who believe that adding wind and solar to the system while closing down thermal stations is a very unsatisfactory strategy – that deep technical analysis of the situation is essential.

“It is like an optical illusion. Some interpret the image in one way and others see it quite differently, and it is very difficult to get your ‘eye’ to see the other interpretation.”

The IES, a multi-disciplinary engineering body founded in 1857, says closing reliable generation sources while increasing intermittent wind and solar generation is “pushing the system towards becoming intrinsically unreliable.”

It points to 1926, when the government decided to drive ahead with the concept of a national grid, requiring substantial investment and reorganisation of the country’s electricity systems.

The complexities of the challenge were examined by an independent group which oversaw construction and operation of the new system. The grid was created, and the cost of electricity decreased significantly.

All the UK’s 14 remaining coal-fired powered stations are due to close by 2024, while Scotland’s two nuclear plants, Torness, in East Lothian, and Hunterston B, in Ayrshire, will only remain operational until 2023.

SSE Thermal and Equinor recently revealed plans to jointly develop Peterhead’s gas-fired power station as a low-carbon station, making it potentially one of the UK’s first to be equipped with carbon capture technology.

Options to support intermittent renewable energy such as carbon capture and storage, hydrogen and nuclear are being explored however, there are concerns that there is a lack of the coordination, collaboration and critical thinking that would come from an ‘engineered’ approach.

The IES suggests the introduction of renewables should be seen as a ‘safety-critical’ project similar to certain construction projects which involve several safety procedures aimed at protecting against the risk of economic, environmental and physical harm.

“There should be an independent multi-disciplinary group who would treat the electricity system as ‘safety-critical’ and use the full powers of modern technology to work out the best way forward,” Mr MacLeod added.

We are a group of citizens concerned about the rapid spread of industrial wind power generation installations across Australia.


  1. Petro Zinchenko says:

    Our new technology detects hot water and ground temperatures down to 5,000 meters. There is a lot of clean and reliable energy underground. This is the future of the planet. It doesn’t depend on the weather. For example. The depth is 4200 meters. Temperature 360 ​​degrees. Geoplutanic power plant with a capacity of 100 Megawatts = 150 million USD.

  2. The very idea of renewable energy having any downsides or threats to anything or anyone nearly caused the ABC’s Paul Barclay to choke on his organic peppermint tea while interviewing a recent guest on his Big Ideas program. French journalist Guillaume Pitron, who wrote The Rare Metals War, provided an unexpected reality check for Barclay who has clearly been living under a heavy coating of institutional green wash, believing in renewables totally clean and harmless image. Pitron explained the reliance of the renewables industry on rare metals and the catastrophic impact their mining was having on the environment, particularly in China. Why haven’t the environment groups pushing for green energy made mention of this, asked Paul. Why indeed? I wonder whether he will get into trouble for having interviewed someone with such heretical notions. The show was broadcast on 9 June and is worth listening to simply to hear Barclay’s reaction to the bad news for the ABC’s favorite multi national industry.

      Further to my comment above.

      Extract from Lynas Rare Earth’s Website. [a miner of this stuff]

      ‘A 3MW direct drive turbine consumes close to 2 tonnes of rare earths permanent magnets. The wind turbine market is expected to account for approximately 30% of the global growth in the use of rare earths magnets from 2015 to 2025’.

      I don’t think many people know that!
