No Potatoes, Warns Irish Times

By Paul Homewood

I though the British press was bad enough!

The latest climate change predictions for Ireland – with temperatures no higher than 10 degrees in summer, and as low as -15 in winter – would have a disastrous impact on agriculture. A climate similar to Iceland’s would make it impossible to grow vegetables such as potatoes and carrots, which means that food prices will soar.

The latest research from Irish and international climate experts shows that Europe is warming twice as fast as the global average. The melting Arctic ice is causing sea levels to rise and this disrupts the main Atlantic current that makes Ireland’s climate temperate. Coastal communities are already feeling the impact of extreme weather patterns. Our vulnerability to climate disruption was evident in 2023, the warmest year on record, when a severe marine heatwave caused damaging flash floods.

Last week’s landslide in Papua New Guinea – caused by extraordinary rainfall – killed 2,000 people. Could such a catastrophe happen in Ireland? In February, Dublin was named as one of 36 major cities most at risk from rising sea levels and flooding.

Then there is worsening air turbulence. One person died and more than 70 people were injured recently on a Singapore Airlines flight because of severe air turbulence and just days later 12 people were injured after a flight from Doha to Dublin experienced turbulence. Studies have found that this problem increased by 55 per cent over the North Atlantic between 1979 and 2020.

Propaganda Overdrive: Wind & Solar Industries Desperate to Prevent Nuclear Powered Future

Crony capitalists, overfed on massive wind and solar subsidies, are pulling out all stops to cruel the chances of a nuclear-powered future.

Nothing sharpens an entrepreneur’s mind like real competition. And, usually, the first move is to knock out the competition before it reaches the field. Which is where Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) comes in.

CSIRO was once committed to advancing science and technology using objective and critical analysis, and all for the benefit of the Country. These days, it’s become the home for wind and solar obsessed activists ready to do the bidding of the rent-seeking class and their political masters.

Last year, they put out a piece of wind and solar propaganda masquerading as ‘research and analysis’. The analysis in their GenCost report was something you’d expect from a struggling high school student: the underlying assumptions were simply risible; the conclusions had those in the know rolling in the aisles; and left CSIRO’s reputation in tatters.

Now that the Liberal/National Federal Opposition are openly backing nuclear power, the Labor/Green Alliance is looking to run as much interference as possible (their wind and solar obsession is purely mercenary, of course) in an effort to assist their paymasters (construction and electrical trade unions and wind and solar outfits etc).

Having been lambasted for their first GenCost report, CSIRO went back to the drawing board and doubled down, with even more nonsensical claims about the cost of nuclear power generation and completely ridiculous claims about wind and solar’s purported capacity to generate electricity. One of the more ludicrous assumptions is that onshore wind power operators are generating power 48% of the time (on average) – across the Eastern Grid the figure is around 28%.

As Judith Sloan outlines below, the latest effort demonstrates that CSIRO has become little more than a propaganda wing of the wind and sun cult, with the singular object of denying Australians safe, reliable and affordable nuclear power.

The cost of nuclear energy is twice the cost of renewables, so sayeth the Commonwealth Scientific and Industrial Research Organisation. But why is the CSIRO in the non-scientific game of providing assumption-driven estimates of the cost of generating electricity in different ways?

On the face of it, it looks like a bit of buck-passing by the Australian Energy Market Operator, which enlisted the assistance of the CSIRO some years ago. This is a task for engineers, economists and accountants – not scientists.

Modelling is not science, and ­estimating costs is also not science. By rights, the CSIRO should have declined the request. Its reputation has been markedly sullied.

Let’s consider the latest version of the CSIRO’s GenCost report. As with all modelling, it’s a case of garbage in, garbage out. The assumptions in it range from the plausible to the absolutely ridiculous.

The most glaring errors in the report are the assumptions about the upfront costs of nuclear plants, their rates of utilisation and their lifespans. The assumption on the capacity of wind power is also laughable and the assumed life­spans of both wind and solar are too long.

It looks suspiciously like a tail-wagging-the-dog exercise: how to ensure that nuclear power looks extraordinarily expensive compared with the preferred renewable energy option of the federal and state governments.

The fact that Australia is the only country of the largest 20 economies in the world not to have nuclear power didn’t seem to awaken the curiosity of the CSIRO team. Should we be assuming that all their governments are simply stupid by having such an expensive form of generation?

And how could it be the case that a very large number of countries are now aggressively in­vesting in more zero-emissions nuclear plants?

Indeed, our main ally, the US, has a target of tripling the amount of nuclear power by 2050.

The international figures are clear: countries with high wind and solar shares in their generation of electricity actually have relatively high electricity prices. They include Germany, Britain, Spain, Denmark and Italy, as well as the states of California and South Australia. By contrast, those countries with very low renewable shares have the cheapest electricity: Russia, United Arab Emirates, Korea and India.

It is worth pausing here to briefly outline the methodology of the GenCost report. It uses levelised cost of electricity, or LCOE, as the key metric – a measure that includes both the cost of installation as well as the expected lifetime of the asset. The cost of the fuel is added, which is zero for wind and solar but material for other means of generation.

The capacity factors of different means of generation are then taken into account. They should vary between 25 and 33 per cent for wind and solar but the GenCost report has onshore wind at 48 per cent and offshore wind at 52 per cent, which are both clearly errors. The capacity factor for nuclear should be in the 90s but in one scenario, the CSIRO puts the figure at 53 per cent, another clanger.

But the key is this: the LCOE is the wrong measure to use. What is required is a system-wide LCOE because of the inherent intermittency of wind and solar and the inviolable objective of 24/7 power. When the wind blows and the sun shines, the cost of generating electricity by these means is very low. But because the wind doesn’t blow all the time and the sun sets, ­expensive back-up (or firming) is required.

This back-up must be added to the cost of both wind and solar. And account must be taken of both extended wind droughts and cloudy periods – short-duration batteries will simply be inadequate. In practical terms, the option of long-­duration, affordable batteries simply doesn’t exist and affordable pumped hydro is not possible in this country.

Last year’s GenCost report was a major hit job on the highly prospective Small Nuclear Reactors which are still being developed, although Canada is further down this path than other countries.

By choosing just one pilot scheme in Utah that was subsequently abandoned, the report was based on the worst-case scenario. It’s hard to avoid the conclusion that this was quite deliberate. This time, the decision was made to include tried and tested large-scale nuclear plants in its comparison of generating costs. The upfront costs of building nuclear plants are very substantial and they can also take some years to complete. There are also quite a few examples of cost blowouts and delays – in Finland and the UK, for example.

The GenCost report uses the relatively successful example of Korea’s nuclear program to estimate the expected capital cost of a large-scale plant. The figure is put at $8700 per kilowatt, which sounds reasonable enough. But the figure is then arbitrarily doubled because it would be the “first-of-a-kind” in Australia. It is simply asserted that “FOAK premiums of up to 100 per cannot be ruled out”.

This is absurd. After all, Australia would be importing the expertise from experienced players were nuclear plants to be built here. And as the nuclear energy industry enjoys a significant renaissance around the world, the number of companies and the depth of talent involved are increasing markedly. By the time Australia is in a position to consent to nuclear plants, it is inconceivable that the FOAK would be double. This assumption makes a substantial difference to the final results.

Stung by the criticism that previous GenCost reports failed to take into account the cost of transmission needed to get renewable energy to the grid, this latest version makes some effort to do so. But instead of focusing on the entire cost of transmission, which feeds into retail prices, only the cost of additional transmission is included in the analysis. Again this is a bias in favour of renewable energy.

Of course, one of the advantages of nuclear plants is that they can be located where existing transmission lines exist; the cost of foregone investment in transmission by rights should be included as reducing the cost of nuclear.

They can also last more than 80 years, even though the GenCost report bizarrely gives them a lifespan of 30 years. Solar and wind are assumed to last 25 years, which is far too long.

Of course, no serious investors would take much notice of the GenCost report or any of the other selective pieces of analysis put out by various government departments. Their analysis would be based on carefully derived figures subject to sensitivity analysis. The key now is for both the federal and state government bans on nuclear power to be lifted so the potential investors can sharpen their pencils and get to work.

Oops…Cleaner Fuels Mean Less Clouds, More Warming!

From the NoTricksZone

An interesting article in Spektrum about a development that we have already reported on here. Apparently there is a connection between cleaner fuels for ships and cloud formation, which means more sunshine and higher temperatures.

However, the reduced content of atmospheric sulphate aerosols has ensured that the cloud droplet density has decreased considerably. This in turn led to a darkening of the sea clouds, which reflected less solar radiation back into space. The team calculated the greatest reduction in aerosol concentration for the North Atlantic, the Caribbean Sea and the South China Sea – regions with the busiest shipping routes. According to the study, the new regulation represents a strong temporary shock to the planet’s net heat uptake. “The effect is consistent with the recently observed strong warming in 2023 and is likely to make the 2020s anomalously warm,” the researchers say. Accordingly, IMO2020 could give global warming a significant boost in the coming years. According to the modeling, a warming rate of 0.24 degrees could be expected for the decade – more than twice as much as the average since 1880.”

And because what should not be cannot be, the Potsdam Institute for Climate Impact Research warns. What a surprise.

Independent researchers are critical of the study, however, as the observation period is too short. In addition, the increase in man-made greenhouse gases continues to play the decisive role in climate change. ‘Caution is required,’ Anders Levermann from the Potsdam Institute for Climate Impact Research (PIK) told dpa. If you look at an effect for such a short period of time, it is generally more prone to error than for longer periods of time.”
