    except if you burn it in moneypoint like we done for decades you spreading radioactive AND toxic ash across country due to south westerly winds

    While a nuclear plant at same location won’t emit anything

    Tho I still think Dublin docks is best

    Ah lads are we genuinely getting into a semantic argument on "coal bad?" now?

    People will do anything for an argument on the Internet eh?

    Boards is in danger of closing very soon, if it's yer thing, go here (use your boards.ie email!)

    I think everyone can agree coal is bad 🤓



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    Most people agree that Nuclear is good when you already have it too.

    What folk have been consistently disagreeing with is that building nuclear is cheap and quick. If Ireland had a glut of resources (and no thats not just €€) e.g nuclear engineers, manufacturing capacity, and experience in building Nuclear, I don't think there would be much push back against Nuclear.

    I don't really care about the Nuclear ban to be honest. Like get rid of it if you want, it doesn't really change the fact that the economics of Nuclear are really god damn hard to justify when it won't generate a single kWh of energy for 2-3 decades, meanwhile tying up 10s of bn in euros which could be used to create renewable energy capacity that exists today.

    what if renewables cant ever provide all the energy we will need, in a sustainable way?

    It won't, nor will nuclear though. You will still need gas/oil reserves to fill in the gaps when nuclear has to shut for maintenance which happens reasonably often.

    For me, if the choice was to spend 20bn on Nuclear which maybe will start generating energy in 20 years time, or spend 20bn in covering any and every roof in Ireland in solar panels, which will definitely produce energy in 5-6 years, i would choose the latter every day of the week



  • Registered Users, Registered Users 2 Posts: 1,799 ✭✭✭bored65


    The current approach still doesn’t get us off gas in 2-3 decades, there are gas plants being planned and build now which will be needed well past that time

    In same time before 2050 nuclear France will get rid off all fossil fuels



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    Do you forsee a scenario where we would build sufficient nuclear to be net zero in 24 years



  • Registered Users, Registered Users 2 Posts: 32,728 ✭✭✭✭Wanderer78


    the main issues with our energy supply is very likely to be beyond our lives, this is why its critical to do what we can right now, i.e. its actually to truly benefit your kids and grand kids, we need to stop being selfish assholse, and really start considering your kids.

    it may actually be possible to run our energy networks purely by renewables and nuclear, if well managed and built, its clearly obvious, if we keep burning fossil fuels, your kids lives will very likely be curtailed, and old age for you and me, could be very miserable, as they try resolve these issues.

    investment in both the short and long term are required, i.e. paneling the sh1te out of the country, and seriously considering all of the alternatives, including nuclear, or your kids are screwed



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    Sure but generated carbon now is worse than generated carbon later. We will be burning far more fossil fuels if we abandon the drive for renewables now and go for a nuclear power plant which won't be built for a generation leaving us that much more dependent on renewables for a greater period.

    Again, I am not opposed to Nuclear in principal, it is just by a long stretch not the fastest way of decarbonising our energy grid at this point.

    whos talking about abandoning anything, we need it all, renewables and nuclear, extreme investment in both, or we re screwed, and more so, your kids are, i wont be surprised if we start to experience black outs from the 30's/40's on wards. high energy demand sectors such as data centers are here to stay, but are clearly being built too fast for our grid to handle, leading me to suspect, serious energy shortages could begin to occur very very soon



  • Registered Users, Registered Users 2 Posts: 1,799 ✭✭✭bored65


    We built Ardnacrusha in 5 years for 20% gdp of early Irish state which be equivalent to 150bn today

    I’m sure we can have the Koreans build a power plant for 28bn in 10 years for us

    The French, Finns or Brits can do it too if you want to get fancy new gen reactors

    hell we gave NAMA 32bn euro not too long ago and didn’t even get clean green electricity out of it



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    We're way too late to be building Nuclear for the 2030s/40s.

    The first NPP if we decided to make it the modus operandi of the government today would not be built until the 2050s.

    Hence why if we have finite resources to spend on energy to decarbonise the grid (which we do, whether we like it or not in the political realities we have) every euro would be much better spent on renewables



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    Remind me how many megawatts of energy Ardnacrusha generated when it opened.

    And how long are the UK taking currently to build Hinkley Point C



  • Registered Users, Registered Users 2 Posts: 1,799 ✭✭✭bored65


    Nearly 100% our energy it generated then, just like a nuclear plant today could



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    1. The government was able to do that back then because it basically had 0 other real government priorities. No health budget to speak of, no real rail or infra investment, no public funded secondary or third level education etc I could go on. 2026. This may be a mad thing to say but you can't necessarily adopt the same approach as you did 100 years ago.
    2. Again, how long are the Brits taking to build Hinckley, our closest real analogue in terms of how this could be built


  • Registered Users, Registered Users 2 Posts: 1,799 ✭✭✭bored65


    Which would still get us to net zero faster and much much cheaper than spending 200+ billion

    If the government keeps on current approach they will lose, and so will any other government after them, impacting so many communities across the country is political suicide

    Handing 28 bn to EU overlords is even worse



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    If you could quantify how much finite money we have to spend is compared to the cost of what you are in favor off, that would be great.

    Not holding my breath waiting on your reply seeing as you still have not given me the number for a mysterious post you accused me of lying in on another related thread.



  • Registered Users, Registered Users 2, Paid Member Posts: 1,736 ✭✭✭Consonata


    Again do you expect Ireland to build any meaningful nuclear in the next 24 years? Given that we have no nuclear industry to speak of, no real resources which could be freighted in easily.

    It's fairly inarguable that if we continue building wind and solar at the pace we are currently doing so, we would fairly comfortably have less carbon emissions than if we were to wait for Nuclear?



  • Registered Users, Registered Users 2 Posts: 16,965 ✭✭✭✭charlie14


    Ardnacrusha power station was 1925 - 1929.

    If you believe the new state had no other pressing priorities for capital expenditure at that time, then you really need to read up on your Irish history

    Great thing about renewables is that it is incremental. It's not one massive project which will take an age before it produces any electricity. Its lots and lots of small projects which incrementally continue to shave off more emissions.

    I believe the latest targets are 34 bn for energy and infra up to 2030, which includes eirgrid upgrades etc.

    https://www.cso.ie/en/releasesandpublications/ep/p-gfsa/governmentfinancestatistics2024april2025/keyfindings/

    Ardnacrusha cost about 20% of Irelands GDP when it was built. For context that's over 100 billion in today's values on 1 project. The government only spent about 148 billion give or take in 2024. Expenditure on a single project today like what was required for Ardnacrusha would require cuts in other areas.

    We don’t have an offshore industry or even a history of offshore industries like oil or for that matter active offshore wind farms either

    So you hire in talent like we do in every sector or pay Koreans who sell the whole package

    we built 9GW of “incremental” wind and solar and what do we have to show for it?

    We built one of the first off shore wind farms? And we have neighbours who are actively building offshore wind atm.

    We've halved our carbon emissions from electricity since 2016?

    We could have gone down the nuclear path with Carnsore Point.

    If we had 70% nuclear and 30% coal our emissions now would be 246 g CO2/KWh. (Based on Moneypoint's 820 g CO2 / KWh)

    Our actual emissions are now lower than that.

    image.png

    Page 20 from epa.ie

    The UK are down to 126g CO2/KWh equivalent to using just 15% coal and 85% zero-carbon. Coal is just that dirty.

    Yes I showed the most recent 8 weeks in that post. Low heating and air-con loads , ideal times for generating surplus.

    You must have somehow missed the posts where I explained how French nuclear output peaked at 430TWh in 2005 and would have been 430TWh in 2015 if they hadn't forgotten how to build nuclear power plants like they used to do.

    IMHO the constant demands for costs is just a distraction from the fact that during the the life of our first windfarm the countries outside Asia who had 84% of the worlds reactors abandoned 40% of the nuclear power plants that started construction. The others were on average a decade late and at least two and a half times the original price.

    Unless and until you can explain how to keep the lights on without increasing emissions you will have to accept that the costs of nuclear are in ADDITION to the path we are on.

    Sizewell-C will cost between £22bn and £100bn depending on who you ask. The higher figure is from the Financial Times who understand things like interest rates.

    The "good" thing about this argument (not what makes it valid, but makes it a good talking point) is that the "nuclear takes too long" claim is a good movable feast.

    I remember when I changed my view of nuclear energy in 2006 I was in a discussion about it here when someone told me something to the effect of "even if we started now, it would take at least 10 years. 10 years from now, it will be too late."

    That was in 2006. 10 years from then was 2016. 10 years after that, people are still claiming that "nuclear takes too long." Because apparently, we won't need lots of low carbon electricity in 10 or 20 years time … or something. Just like we wouldn't looking forward from 2006.

    But to bring back another argument I've seen on this thread "what do we use in the meantime," I'd also like to turn this around to renewables advocates. What do we do while we wait for your plans to result in lower CO2 energy that is more secure than importing gas? (which at present we seem to be doubling down on :o )

    Just keep burning gas? If so, where does that come from?

    There is currently nothing which we can do to reduce emissions faster than building more renewables. That's just a fact atm, its self evidential given the amount of renewables we've built and, as I've said, how our emissions have halved in 10 years



  • Registered Users, Registered Users 2, Paid Member Posts: 10,047 ✭✭✭✭SeanW


    1. As it stands, no amount of building renewables can compensate for the fact that solar panels and windmill require the co-operation of the weather, among a litany of other problems.
    2. We have another issue in that renewables seem to require gas specifically as a backup fuel (due to the flexibility of some gas plant types), and the supply of that can no longer be considered secure (after the start of the Russo-Iranian in 2022 and the US-Iran war in 2026). I would argue that security of supply is now as great an issue as CO2, if not more so. For that reason, I consider a pivot away from gas fired power generation to be the main concern right now.

    We commit to Nuclear over Renewables and we will be more dependent on Gas in the near term? Which is probably the only thing which should matter at the moment even if you don't care about emissions.
