    Agree with the pessimistic opinion, except that doing some of that might stop the tax payer, sorry, government, being killed by carbon fines.

    Agree that carbon taxes hurt the poor the worst, the paradox of the boots comes to mind, but if it was worldwide and hit everyone we might see less private jet usage, less mega yachts etc. It would be crappy for the likes of Pawel and Angelika, and John and Mary, who moved to new places with the idea of cheap and easy travel back home potentially returning to bygone eras where flights are a luxury not an assumption.

    But something has to be done.

    This was interesting I thought. We've close to halves our per capita carbon emissions in 21 years. (Of course, population increase has then undone most of that)


    It doesn't feel like we've achieved that though. I wonder what's driving it? Is it real, or is it like the daft suggestion discussed earlier that we cull cows to reduce our carbon, but really we're just moving the carbon somewhere else?


    I was looking at how national figures are calculated and found a source (https://ourworldindata.org/co2-emissions-from-aviation) that suggests air travel isn't included in national figures - or at least international flights aren't, and we have very few domestic flights. But between 2000 and 2019, passenger numbers in Dublin Airport went from 14m to 33m. Then there's other airports and also freight/cargo flights.


    If it is the case that that's not in our figures, then not only are we kidding ourselves on the progress we're making reducing emissions, but also reducing one of the fastest-growing and most damaging sources of carbon (because much of it is released in the thin high atmosphere) is nobody's responsibility.


    Don't know if anyone has any insights on that?

    Tourism, beef and being a tax haven are our three pillars of industry, if we kill the cows and stop the flights we better make sure we continue to allow big tech and big pharma to rest their monies in our accounts or that's all folks.

    i remember reading stories that aviation would take many years to recover from covid; this is from two weeks ago.

    also - not only is aviation not included in national figures, jet fuel is exempt from carbon taxes and excise.

    Would this count as a major subsidy towards fossil in Ireland?



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 49,441 CMod ✭✭✭✭magicbastarder


    I think it's not just in Ireland, it's Europe wide.



  • Registered Users Posts: 13,464 ✭✭✭✭Igotadose


    So, let's add a few hundred million people to Ireland from, say, China or the US and problem solved? More people worldwide, more CO2? I'm glad Ireland has reduced its emissions in a year of Lockdown or recovering economy. But it means nothing, unless you're proposing global lockdown accompanied by massive reduction in consumption



  • Moderators, Sports Moderators Posts: 7,211 Mod ✭✭✭✭cdeb


    Yeah, there's definitely a correlation. There's lots of factors so you can't say population and carbon are directly linked. But it would be fair to say there's at least a moderate correlation. It's hard to see how people could ever stop generating carbon. (And we don't need to do that, hence nett zero)


    We have been steadily reducing per capita emissions for the last 20 years though. It's not a covid thing. (And it may just be we're outsourcing emissions elsewhere)

    There was a statement above saying something along the lines of little fossil fuel subsidy in Ireland



  • Registered Users Posts: 555 ✭✭✭InAtFullBack


    The fact that carbon taxes and even to a large extent excise duty taxes are not applied to aviation fuel does not equal that industry getting a subsidy. It just means that the well to do get to jet off on their jollies without much added expense. Much like when motor tax was reduced for brand new cars in mid-2008 during a crippling recession. The well-to-do were shielded from the €500+ per annum charges.

    Something has to be done.

    This is where the crux of the problem lies;

    Some quarters want to reduce everyone's quality of life in order to achieve the 'something has to be done' by dictating what you can and cannot do.

    Other quarters want to do the above a little more subtly by hitting you in the pocket so your hard earned cash can only go so far.

    There are some who employ a bit of both to achieve it.

    The voting public by and large despise both approaches and any combination of parts of both, hence the voting public are starting to shift to parties or independents who oppose the two strategies above.

    The way forward is finding solid solutions that allow people to uphold their current lifestyle quality at current or lower costs. The first step to this is to develop low-cost energy that powers transport and electricity with very low or nil emissions. Nuclear energy hits the second requirement, but sadly tanks on the low-cost front. Renewable energy, especially wind it very unreliable - solar has some promise as we know when there is light and when there is dark, which is why I would support a large scale solar rooftop programme in Ireland capitalised by the government and paid back by the 'free' energy it would then produce.

    The renewable power industry looks on with bitter envy at the fossil fuel industry and how they made billions over the decades and want the same for themselves in the coming decades. As ever, you and me the consumer will bend over and pay handsomely for energy going forward - you'll just be shafted by a different provider.

    Just for a little giggle on this damp and dreary July night




  • Registered Users Posts: 20,047 ✭✭✭✭cnocbui


    Nuclear is a lot cheaper than either solar or offshore wind if costed by the actual energy produced. A sleight of hand is currently used to cost renewables, called LCOE, which takes no account of capacity factor and is used to make them look cheap.



  • Registered Users Posts: 4,948 ✭✭✭Shoog


    That is the very definition of a subsidy, when one sector gets preferential treatment which gives it an economic advantage.

    Most of the subsidies for fossil fuels are not direct payments, they are things like tax breaks.



  • Registered Users Posts: 4,948 ✭✭✭Shoog


    Nuclear is subsidized at every stage of its life cycle. Here's an example, how much is insurance for nuclear and who pays it ? Who pays decommissioning costs and waste storage costs ?



  • Registered Users Posts: 555 ✭✭✭InAtFullBack


    A very interesting piece which lends alot of explanation to the causes of recent increased rainfalls and heat across parts of the globe.



  • Registered Users Posts: 20,047 ✭✭✭✭cnocbui


    Wind and solar are subsidised massively. You don't think Solar in Ireland with a capacity factor of only 10.5% is commercially viable, do you?

    German lawmakers backed an extensive revision of the country’s EEG clean-energy law to curb subsidies and slow gains in power prices that are the second-costliest in the European Union.

    You think renewables are massively subsidised in Germany, but not in Ireland? Can I sell you a bridge, slightly used?

    If you install 1 GW of solar in this country, it will only produce 105 MW of power for a cost - based on US utility scale solar - of €800 million.

    RESS = Renewable Energy Support Scheme

    High grid connection costs resulted in a solar strike price in Ireland’s first Renewable Electricity Support Scheme (RESS) auction “significantly higher than anywhere else in Europe” according to the Irish Solar Energy Association(ISEA). The overall strike price - €74.08/MWh (£66.90/MWh) - came in at over double the sorts of prices seen in the UK’s Contracts for Difference scheme, the most recent of which saw prices run as low as £39.65/MWh.

    Couldn't actually be due to Ireland being a stupid place to install solar, at slightly less than half the capacity factor in Spain, for the same capital cost?

    That strike price means a return on capital of 8.11%, which means it's 9 years roughly, just to break even. If you are borrowing money to build the thing, good luck to you.

    Nuclear is expensive, right? Needs huge subsidies, according to you... The Barakah NPP in the UAE, just completed, cost €4.07 Billion per GW.

    That's really expensive compared to €800 million per GW for solar, right?

    Wrong, because the capacity factor for that NPP would be about 96.4% vs 10.5% for solar, so in terms of the amount of electricity actually produced, it's cheaper. This means that in a year you get about 8.4096 TWh vs Solar at 919.8 GWh. Using the same solar strike price, Your 'expensive' NPP is going to pay for itself in just 6.5 years and your return on capital is 15.31%, not 8.11%

    You get so much more money back from Nuclear over it's 60 year life span - paid off in just 6.5 years, remember - it pays it's own way in terms of decommissioning and waste. Since states 'insure' nuclear, there is actually no cost, because there is no premium being paid, there is only a cost in the extremely unlikely event of a payout.

    Nuclear has vast hidden costs (insurance, etc) and significant operational costs. No amount of subsidy has persuaded the markets to invest in it over renewables, enough said.

    You just make sh​it up:

    Nuclear power plants are expensive to build but relatively cheap to run.

    You want to see something with massive hidden costs, take a good look at offshore wind. There is endless media blagg about but how 'cheap' it is - never mentioning low capacity factors or the costs that entails elsewhere to compensate for, but the biggest hidden cost is maintainance - a whopping 1.2-1.4c per KWh generated.



  • Registered Users Posts: 4,948 ✭✭✭Shoog


    Your analysis is always based upon ignoring the European grid model on which renewables are based. Having significant overcapacity means that for most of the time Ireland will be selling electricity to the EU wide grid. Earning significant returns on capitol investment.

    There is also the fact that Ireland is both to small to accomdate available nuclear plant and would need to build significant overcapacity of nuclear to ensure relatively reliable supply. Large point source grid elements are intrinsically destabalizing to grids.

    But insurance is the clincher, nuclear is uninsurable since insurance companies understand risk even if nuclear advocates do not.



  • Registered Users Posts: 4,574 ✭✭✭jackboy


    We should not set up a renewables energy based system until storage solutions are available and in place. Without this we will need back up fossil fuel or nuclear. Storage solutions for renewables are years or decades off yet.



  • Registered Users Posts: 4,948 ✭✭✭Shoog


    Large batteries are now available and high voltage DC can take care of much of the necessary load balancing. For the relatively small number of times these fail to deliver then gas is available. The overall savings in emissions are so large that to wait for nuclear to be built or to do nothing are simply not acceptable choices.



  • Registered Users Posts: 20,047 ✭✭✭✭cnocbui


    You just wont stop with the BS..

    Finland has a population of over 5.53 million


    Finland opens nuclear power plant amid concerns of European energy war

    Slovenia and Croatia have a combined population of about 6 million. They share a nuclear reactor.

    Slovakia has a population comparable to Ireland and has 4 nuclear reactors.

    Current ESB estimates are for a massive surge in demand for electricity in Ireland due to electrification of transport and to replace fossil fuel home heating with heat pumps - which will require more power than EV's - and the production of hydrogen for fossil fuel replacement. Overcapacity, which it wouldn't be, would be absolutely necessary to generate power for EV's and heat pumps and also to run electrolysers to produce hydrogen.

    Fun fact; electrolysers don't like being turned on and off and are a terrible match for intermittent power. They are a perfect match for nuclear power as it's a constant supply, green and cheap, which suits their technical requirements and which is most economical financially in terms of amortising their capital cost.



  • Registered Users Posts: 4,948 ✭✭✭Shoog


    Hydrogen is a massively expensive and inefficient method of energy storage. The losses at every stage are horrendous. Batteries are currently cheap and will remain ahead of hydrogen as their price continues to fall. Battery systems are been built and placed onto the grid as we speak where as green hydrogen is still very much at the concept stage.

    Your model is flawed because it cannot address the NetZero objectives the government are committed to. Why - because nuclear only starts to offset carbon once it goes on grid with a realistic time frame of 20 years for Ireland.

    This tedious as it has been discussed to death on its own thread. Take it up there.



  • Registered Users Posts: 20,047 ✭✭✭✭cnocbui


    You don't understand how or why batteries are used in the grid, clearly. They are basically used as big slow cycle capacitors. A little something to tide you over while you rush to get the real power from somewhere else because your renewables just fell over because of their intermittancy and unreliability - as happened epically in South Australia, causing them to build the worlds largest battery (at the time).

    You better get a grip on the reality of hydrogen, because the ESB masterplan for this country calls for gargantuan amounts of hydrogen energy storage:

    Our projected storage needs running at a trillion Tesla Power walls equivalent is a consequence of Ireland's stupidity in not allowing the use of nuclear energy. 27 Hiroshima atomic bombs worth of stored hydrogen because of a fear of nuclear - there's some epic irony in there.

    "Luckily, in the history of humanity, nothing bad has ever happened from lighting hydrogen." Matt Damon - The Martian.

    That's €6,817 Trillion euros worth of batteries at Powerwall prices.

    If you want to replace hydrocarbon fuels in transport, and batteries are expensive and very heavy, then you are going to have to suck up the inefficiencies inherent in hydrogen. Don't listen to me, take it from the ESB. Argue with them, not me.



  • Registered Users Posts: 4,574 ✭✭✭jackboy


    Batteries in conjunction with renewables are not used anywhere as a replacement of fossil fuels/nuclear. This is still a theoretical idea.



  • Registered Users Posts: 913 ✭✭✭buzzerxx


    Its caused by the cows farting. LOL Irish Government's plans to slaughter 200,000 cows at a cost of €600 million… under the guise of a #ClimateEmergency.

    The airlines of the world, armies, war and space programs, are exempt from carbon calculations and taxes. Climate change is a taxable commodity nothing more, it's not about saving the planet. The Climate is doing exactly what it has done since the formation of the planet
