> The actual causes of electricity cost rises in Ireland being higher than Europe are

Wrong comparison. Most of Europe has way too high electricity prices.

It seems logical that ending the use of existing coal energy infrastructure puts upward pressure on prices. Coal is cheap, abundant, energy dense.

Yes, burning coal causes lots of problems and I support ending it's use, but this is besides the point.

>Coal is cheap

No it's not. I'm not talking about the environment either, coal plants are just straight-up more expensive than gas plants and renewables.

Coal plants are necessarily steam turbines and not internal combustion, because coal is filthy and the mercury/sulfur/etc would wreck the guts of any machinery it goes through. Thus, it's only used to boil water.

Gas turbines don't have that problem, so they spin the turbine with the combustion products directly. They're far more efficient, the machines are smaller and cheaper, and because you don't need to wait for a giant kettle to boil before ramping up the power, they're far more flexible and responsive to demand. It also helps that the gas is fed with a gas pipe, whereas coal needs to be fed with a bobcat.

Which is why nobody is building new coal plants - they're way more expensive than gas plants, even if the gas fuel itself is more expensive than coal.

> Coal is cheap, abundant, energy dense.

Coal is neither cheap nor abundant in Ireland.

This. Fossil fuels are not cheap in Ireland, I think we only produce a small quantity of natural gas, everything else is imported. Ireland should be running towards renewables, we have no indigenous fossil fuels industry to lose and every watt we generate from renewables is money that stays in Ireland. We should be focused on reducing nimbyism and building out renewables.

Coal is cheap and abundant in the English Midlands, which explains much of the industrial revolution starting there.

Said collieries, which if put back into service, would be able to cheaply get coal to Ireland via barge at no great cost or latency.

Coal also isn’t really energy dense since so much of the energy is wasted when converting to electricity

But it is abundant in Russia, Ukraine, Germany, and Poland. Also, there is nuclear power in France.

However, Russia and Ukraine are at war. Germany is willing to go green and destroy itself. EU hates Poland and other east European countries. And EU and the rest of the world can't disassociate nuclear power with weapons.

So I guess EU can enjoy their limited and expensive green energy.

> It seems logical that ending the use of existing coal energy infrastructure puts upward pressure on prices

Only if you externalize environmental costs. The point is that coal is actually really expensive. The only real argument is how fast the implicit subsidy on these externalized costs should be removed. The world has had decades to slowly remove these subsidies and failed to do so. The impacts caused by these externalized factors are starting to stack up and so should the prices.

> Most Europe has way too high electricity prices.

Way to high compared to what? Some countries do not even have a problem with prices but with capacity (Netherlands). They would be willing to pay but they do not have the grid to deliver where the thing is needed, and it's hard to build new grids in high density areas.

> It seems logical that ending the use of existing coal energy infrastructure lead to an increase of prises.

But doesn't this depend a lot on planning and investing in alternatives rather the just closing or not the coal? Sure, if you just close one source and leave everything else untouched prices will increase, but doesn't sound like the smartest approach overall...

Way to high compared to actual cost. Almost half of fuel and electricity costs in Germany is tax.

here some comparison chart, 2nd image in the article below:

https://ec.europa.eu/eurostat/statistics-explained/images/th...

https://ec.europa.eu/eurostat/statistics-explained/index.php...

there are 2-2.5x times differences between highest and lowest, of 25-30 countries

And here is some current/future (??) prices/increases, which i have no idea where they come from:

If you don't count the externalities, sure. Healthcare is a cost too. We need more holistic accounting, the financialising of everything into a tidy but ultimately false P&L column is literally killing us.
> Coal is cheap, abundant, energy dense.

Nuclear defeats coal in all of these aspects, aside from the high upfront cost.

Upfront costs... then running costs (in the UK at least, it has to command a premium over other energy prices, to be profitable)... afterwards costs (in the UK no private company is on the hook for decommissioning their nuclear plants, the population will pick up that cost through taxes)...

But sure, nuclear is cheap if you ignore all those things.

> Coal is cheap

Only if you ignore all externalities including:

- environmental damage from mining (yes this exists for renewables too)

- global warming

- pollution on city infrastructure

- pollution on health

- the sunk costs causing higher transition costs when inevitably you transfer to renewables anyways.

>Only if you ignore all externalities

Not even then. Coal is dead, and gas killed it. The externalities are a distraction, coal plants are just straight-up uneconomic.

> Only if you ignore all externalities

Do not discount how easy that is to do. Your list is of costs not to any bottom line of a company with bean counters. Those external costs are out side the scope of their concerns. Your list of concerns would be something for C-suite types, but the pressure of stock prices again make the external costs easy to set aside.

Sure, but as a consumer you can also care about these things.

Coal is teetering on the edge of economic viability. In the US, our coal-obsessed administration is now at the point of forcing coal power plants to remain operational against the wishes of their owners who want to shut them down as they’re no longer profitable.
