    I honestly thought this shite was done and dusted, but here we are, with an oil boss on Newstalk spouting utter drivel in relation to climate change

    He was made to look a right muppet though

    Think renewable tech is definitely needed but it's not the silver bullet the greens make it out to be



  • Registered Users Posts: 12,993 ✭✭✭✭JRant


    He's fairly on the money if you actually listen to what he's saying. Right now, there is no climate crisis. And making fossil fuels more expensive does actually lead to an increase in poverty.

    "Well, yeah, you know, that's just, like, your opinion, man"

    Nobody claim engine block is made of copper or manganese apart from you. Iron and aluminium are not included in that picture simply because there is no actual or projected shortage of them compared to quite real shortage of other minerals mentioned when crazy targets presented by government and politicians in their quest for green sainthood are taken seriously.

    This was a somewhat naive, but understandable position to take pre 2022.

    Since then it has become clear that shortfalls in gas and nuclear generation will lead to the burning of coal and lignite, because energy rationing was not seen as a viable alternative.

    Fossil fuel will continue to be burnt to keep the lights on during the normal planning, construction and commissioning delays for nuclear. This will add extra years to the time it takes for them to be carbon neutral.

    Nuclear is all or nothing, 50% of the new nuclear constructions in last 30 years in the USA were cancelled at an average cost of $4.5Bn per reactor and a huge carbon footprint. The failure rate is massive overhead compared to other power plants. The other plants, of course, are years late.

    Even after the delayed grid connection a nuclear plant will typically take 6 months to begin full commercial operation. Though it's looking more like 12 months average for the EPR's in China , Finland and France.

    Wind turbines are carbon neutral in 7-9 months, including the concrete and decommissioning. That's the Renewables deliver increasing power as you roll them out so a project that takes a couple of years to rollout is probably carbon neutral before it's finished.



    Last year in the EU there was a gas embargo AND a 500 year drought which reduced hydro by 66 TWh. Instead of Nuclear coming to the rescue it's output dropped by 119 TWh. It was so bad that the 28 TWh increase in coal could have been a reduction if nuclear had been as reliable as it's supporters suggest it is.


    This is last year's growth in solar. Multiply that by the average time it takes to build a Generation III nuclear power plant in the EU. Look at the Low Countries and Poland to see where we will be. Solar like wind is seasonal here so they complement each other.

    I love the Cool worlds astronomy videos but he really shows how much of a problem the supply of batteries could be for EVs in future.

    Who would thought that 5GW of onshore wind with a capacity factor of 1/3rd on a 5GW grid would produce 1/3rd of the power ?



  • Registered Users Posts: 9,788 ✭✭✭antoinolachtnai


    It’s a way of saving on gas. The higher the price of gas and the more volatile the European gas security becomes, the more sense it makes.



  • Registered Users Posts: 11,357 ✭✭✭✭rossie1977


    Ireland has barely scratched the surface regarding the potential of wind power and still it generates 1/3 of our total needs...

    We have practically no off shore wind farms despite the west Atlantic being the windiest place in Europe. Northern Inishowen (Malin Head) is the windiest part of Ireland by a distance but to my knowledge no winds farms there either

    We are a wind swept island being battered daily by the Atlantic. We should be producing so much wind and water power that we have countries lining up to buy from us.

    It's one thing to justify degrading our natural environment to provide for our own energy needs.

    But as usual, greed creeps in quickly and soon we're talking about degradation on a wider basis, so some people can make money out of it.



  • Registered Users Posts: 3,594 ✭✭✭Pa ElGrande



    You are asking the wrong questions. How do you generate return on capital for generators that only work 25% to 40% of the time and not always when electricity is demanded? How do you afford a system where generation can within 24 hours, go from consuming power to one that generates too much power and must be curtailed, with curtailment payments. Like it or not, us consumers pay for that inefficiency. It does not matter how many turbines there are when there is no wind there is no generation, not only that, anticyclones can and do settle in across Western Europe leaving the entire continent short of wind generation at the same time. Go look into the business model, it's not cheap and the evidence over the past 2 decades show a correlation between the increases in electricity prices with the penetration of unreliable generation right across Europe.

    Net Zero means we are paying for the destruction of our economy and society in pursuit of an unachievable and pointless policy.

    Its incredible the amount of investment going into active travel and public transport now. Long overdue and starting from an extremely low base, but hopefully long may it continue

    The priority for the €3.5 billion spending by the Department of Transport this year is the development of local link and town bus services, Minister for Transport Eamon Ryan has said.

    My Ryan said although road building would continue, the coming two years would see a shift in funding of two-to-one in favour of active travel and public transport.

    He revealed just €240.009 million of €1.387 billion earmarked for roads and road safety has been allocated to the construction of new national roads this year. Some €70 million will be spent on new regional and local road improvement schemes.

    The Minister told TDs and Senators €358 million would be invested this year in “active travel” including the Safe Routes to School scheme on which the Department of Transport was working with local authorities to design and implement changes that would make it more attractive for people to chose active or public transport over the private car.



  • Registered Users Posts: 9,788 ✭✭✭antoinolachtnai



    Your question is easily answered. The answer is the capacity remuneration mechanism which forms part of the all-Ireland electricity market.

    What is a curtailment payment? A wind farm does not get paid for curtailed generation.



  • Registered Users Posts: 10,460 ✭✭✭✭tom1ie


    So does a wind farm only get paid when the wind blowing? Ie when it’s generating?



  • Registered Users Posts: 403 ✭✭Robert Nairac


    Ahh sure, build more cycles lanes to nowhere that nobody even wants to use. Park your bike up in the city and get it nicked. Ideology over all else.



  • Registered Users Posts: 24,062 ✭✭✭✭Larbre34


    Your Boards ID is pretty insensitive, no?

    Did you not think of Hitler or Dr Mengele? Maybe Jamie Bulger or Mary Boyle?



  • Moderators, Recreation & Hobbies Moderators, Science, Health & Environment Moderators, Technology & Internet Moderators Posts: 91,586 Mod ✭✭✭✭Capt'n Midnight


    Nope. That's not how capacity factor works. It means the average power would be a third of nameplate capacity.

    Nuclear is the one where output is either close to 100% or there's no power at all.


    Here's 5 year data from UK offshore wind farms. Individually they produced almost no power for the final 10% of the time at their location.

    Collectively the average of ALL farms was above 15.9% 75% of the time. And I'd imagine much of time it was below that was during good summer weather when solar would be available.



  • Registered Users Posts: 9,788 ✭✭✭antoinolachtnai


    Yes. There is one exception, when the local grid can’t bear the output and the wind farm has already sold its output into the ex ante market.

    Wind is not that prevalent in europe energy makeup and even though there are plans to put more turbines on problems wont go away as wind is finicky and not a stable source as other posters said time and again.

    Another thing is that as soon as russia situation normalize which may be closer than some people think everyone will happily flock to cheap gas again. It is all about money anyway. Governments wont be able to subsidy green energy for much longer since this is unable to power manufacturing and economy.

    If you don't mind rather than scaremongering I prefer to use the actual numbers on actual signed contracts.

    It's the wholesale price that matters. In the UK new nuclear is 2.7 times as expensive as offshore wind and that's for 2.3 times as many years. Actually it's a lot longer because the turbines are spinning while nuclear is still years away. If they start another new nuclear plant it would be competing with the marginal cost of wind or solar.


    Renewables are usually paid for by investors, so capital cost to taxpayer is zero no matter how many billions you claim. Nuclear needs state guarantees so the taxpayer is on the hook for billions, and then there's cost of the spinning reserve and decommissioning and waste etc.

    By rights nuclear should also include the costs of keeping old inefficient fossil fuel plant running and the fuel they use. Finland's new nuclear power plant will spend the next 15 years offsetting the carbon used to keep the lights on during it's delay, only then will it start to offset it's own carbon. Last year Finland increased wind by 75% which is probably full-lifecycle carbon neutral by now.

    That's already changed.

    In 2022 nuclear should have come to the rescue, instead it was down to 21.9% , gas 19.9%, coal 16% , hydro 10%, wind 15% , solar 7.3% , biofuel 6%

    In 2022 wind and solar output increased by 78TWh which was an eighth of what nuclear produced. Seven more years like that you could replace nuclear.

    And Germany will now be phasing coal out 8 years ahead of schedule. Hydro dropped because of an 500 year drought which hopefully isn't a symptom of climate change.


    Coal produces 16% (447 TWh), gas 20% (557 TWh) and other fossil fuels 3.6% (100 TWh). Nuclear remains the single largest contributor to EU electricity at 22% (613 TWh) of the mix. 15% (420 TWh) is produced by wind and 7.3% (203 TWh) is produced by solar. Combined, wind and solar produce more electricity than any other fuel (22%, 623 TWh). The rest is produced by hydro (10%, 283 TWh), bioenergy (6%, 167 TWh) and other renewables (0.2%, 6.7 TWh).

    In the UK new nuclear is 2.7 times as expensive as offshore wind

    UK new nuclear is about the same price as IRISH ONSHORE wind.

    Renewables are usually paid for by investors, so capital cost to taxpayer is zero no matter how many billions you claim. Nuclear needs state guarantees so the taxpayer is on the hook for billions...

    Funny how the investors are flocking to renewables then, instead of all that free state money for nuclear? Of course the fact of the matter is that renewables get a state guaranteed minimum price and it's so outrageously high that venture vultures everywhere are flocking to it. Let's see how they fare when high interest rates and commodity inflation kick in. (We've already seen the start of it with turbine manufacturers taking losses).



  • Registered Users Posts: 6,200 ✭✭✭crisco10



    Are you basing the Onshore Wind Price on the most recent RESS auction that was €98/MWh ? If so, it's important to note that value is not indexed. i.e. it won't change at all, and thus the real price will be coming down by at least a few percent each year (more in the last year) until the end of the CfD mechanism.



  • Registered Users Posts: 3,055 ✭✭✭patnor1011


    Data used are from november 21 to november 22. I highly doubt much changed in 2 months other than decrease in gas followed by increase in coal as a result of russia ukraine conflict. Germany may talk about phasing out coal fact is they actually are increasing its use. And they will increase its use even more.

    Your picture is from 2021 and you need to read to the end of your link ...

    A new report from Ember highlights how the transition made considerable progress in 2022, with solar and wind power (22%) overtaking natural gas (20%) in electricity generation for the first time ever.

    While 2022 did see an increase in fossil fuel electricity generation for the EU, Ember is expecting it to decline in 2023 by as much as 20%.

    EU voting to ban all ICE car & vans new sales from 2035 across the block

    THE EUROPEAN PARLIAMENT has today given its final approval to a ban on new sales of carbon-emitting petrol and diesel cars by 2035, with a view to getting them off the continent’s roads by mid-century.

    Irelands ban will take effect from 2030



  • Registered Users Posts: 24,062 ✭✭✭✭Larbre34


    Realistically, Ireland's ban will move out to 2035 in line with the slowest movers of the Union, because we have no vehicle manufacturing industry and don't have a choice what vehicles are offered for the market.

    That said, I think the lag will be in the larger passenger car and mid-commercial vehicle segments. Most of the mainstream model segments will likely be fully EV offerings even before 2030.

    There does remain the issue of heavy plant and machinery though. Diesel engine characteristics and gearing have inherent technical advantages for doing work and that won't be easily resolved.



  • Posts: 0 [Deleted User]


    Based on current car sales data, EV's will over take petrol and diesel (not the combined figure) in new car sales within the next 15-20 months if the same rate of growth holds

    Source: SIMI data, graphs my own

    EV vans have been coming on stream over the last 12 months and there's loads in the pipeline

    Heavier machines are often very niche so those will take longer. That being said, if all we were left with was diesel heavy machines it wouldn't be a show stopper given the low volume.

    And what will the benefit be. We are still going to be burning gas and coal to generate the electricity to charge them much of the time.
