    Except that it was a financial advantage as explained previously.

    Some people here seen shocked that some EV drivers might care about the environment



  • Registered Users, Registered Users 2 Posts: 5,890 ✭✭✭creedp


    No some people take issue with the view that all EV drivers buy the cars predominantly on environmental grounds. The corollary of this view is that 'climate change deniers' wouldn't buy them because obviously they have no concern for the environment. The strange thing is that all the EV drivers you know have bought them on environmental grounds whereas all the ones I know have bought predominantly on financial grounds. What gives....



  • Registered Users, Registered Users 2 Posts: 1,564 ✭✭✭Ionised


    What about the other reasons why some drive EVs?

    My main reason is the preference to how an EV actually drives, plus the joy of preheating on winter mornings. Could not care less about financial sensibilities or the impact on the wider environment.

    1. Coal Driven EVs are always better on usage emissions than a Petrol car as shown by the article you sourced.
    2. We're an Irish website, driving an EV here is predominately powered by Gas + Wind.

    I don't think people are rattled, we're just irritated by the OPEC propaganda you seem to be sourcing your information from.



  • Registered Users, Registered Users 2 Posts: 22,470 ✭✭✭✭ELM327


    Irish electricity is generally shown (by Eirgrid) as having single digit percentages of coal generation. EVs are generally charged at home, either at night and/or by solar PV. Night electricity tends towards being the greenest (but not always). PV is of course green.

    Now I have PV and we have had 6 EVs so far. I have been driving EVs since 2016, and couldnt give a crap about environmentalist nonsense. For me it's about cost - TCO cost - ,dependable uptime and low maintenance.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    Regarding point 1 I'm not overly convinced, even the poster I replied to initially put forward evidence that amounted to maybe just 10% improvement, hardly going to dent those 8 billion tonnes of coal is it?

    Regarding point 2, the problem is global warming, not Irish warming, just because we are using less coal here won't solve the global problem. ~80% of our energy comes from fossil fuels, so unless I'm missing something then ~80% of our global ev fleet is being powered by fossil fuels that might be just 10% better than if they were ICE instead.


    This idea that ev's will help make the world carbon neutral is surely another big lie?



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    I'd like to see our energy mix on the coldest days last week, I'd be sure Moneypoint kept the lights on when the renewables took a few days off.

    People need to rethink their close Moneypoint agenda. Given the situation with gas supplies this year are people really thinking this one through?

    Moneypoint is our largest energy store, having 3 months, compared to just 5 days of gas reserves.



  • Registered Users, Registered Users 2 Posts: 22,470 ✭✭✭✭ELM327


    I have no issue with coal, in fact it's better than russian gas. Long term we need to move away from all fossil fuels of course.

    Close Moneypoint is fine, once you have a replacement. Which we don't.



  • Registered Users, Registered Users 2 Posts: 6,276 ✭✭✭crisco10



    1 question, what's your proposed solution? Do nothing until we have a solution that reduces the problem all the way to zero in one move?


    I can't get the data on my phone but eirgrid reported that on the record demand last week it was interconnection and batteries that kept the lights on.

    Well at the moment we are achieving little to nothing. Electric cars ain't solving it anyway.

    Instead of closing Moneypoint in 2025 we are now seemingly converting it to oil instead. But we built Moneypoint because we were over exposed to oil in the 1970's oil crisis and now we are going back to increased oil dependency.

    Our 1 million electric cars on the road by 2030 will be fun to watch for sure.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    Look at those beautiful fossil fuels powering all our snazzy clean electric cars, all set to preheat before we sit into them on those frosty mornings.



  • Registered Users, Registered Users 2 Posts: 6,276 ✭✭✭crisco10


    You can't take a snapshot like that. It means nothing. How about the snapshot when it's >75% wind?


    For example, right now we're mostly cooking our dinner with wind.




  • Registered Users, Registered Users 2 Posts: 6,276 ✭✭✭crisco10


    So still no solution, other than a tonne of whataboutery around anything that's currently being done.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    So what is being done?

    Why is global coal consumption not falling?

    Why is Moneypoint no longer being closed?

    How is our million electric cars by 2030 looking?

    Why did we cut duty on petrol and diesel?

    Why do we keep missing our climate change targets?



  • Registered Users, Registered Users 2 Posts: 6,276 ✭✭✭crisco10


    A considerable contributing factor is I would wager because a lot of people refuse to believe the information put in front of them. E.g. EVs are cleaner than ICE over their lifetime.

    Here we go again. A whopping 10%, 30%, even 50% more efficient, so what? They are still fossil fuel powered cars destroying the planet, they still need coal to move.



  • Registered Users, Registered Users 2 Posts: 6,276 ✭✭✭crisco10


    Yea...look at the thread title. Then I'll ask the same question, do we need a 100% solution before we do anything?



  • Moderators, Science, Health & Environment Moderators Posts: 20,015 Mod ✭✭✭✭Sam Russell


    I think the whole push for people to convert to EV vehicles is not to save the planet but to save the motor industry.

    To save the planet, public transport, bicycles, and walking should be the solution. OK, include electric scooters provide a brilliant low carbon alternative to EV cars for mid range where there is no public transport. Of course, avoiding unnecessary journeys is better - by using zoom type meetings or simply not going if it can be avoided. Now many journeys are needed but many are not.

    Now, reducing the cost of bus and train has increased use. That just needs to be expanded - more buses and trains and lower fares.

    How can conveying one single person in a 2.5 tonne vehicle, however it is powered, be sustainable?



  • Registered Users, Registered Users 2 Posts: 5,890 ✭✭✭creedp


    I thought the problem is that too many people want to drive EVs. Demand far exceeds supply so is it individuals or corporations you should be focusing your attention on.



  • Registered Users, Registered Users 2 Posts: 5,890 ✭✭✭creedp


    +1. I would say the majority of EV owners are similarly motivated.

    Which causes more emissions burning coal in a power station to power an EV or burning refined oil to move a petrol car? Your own provided source shows that today even a coal powered EV is better than the petrol burning alternative. If you aren't convinced go fund a study and publish it in peer reviewed journals.

    Next question, do the usage emissions of a petrol car improve as the generation sources on the grid changes?

    It appears you are heavily invested in the continued success of the oil industry and want us to remain dependent on non indigenous sources of fuel, but the rest of us can see through your very shallow attempts to prop up the oil producing nations.

  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    I'll tell you something. I know a lot of people late teens and into their 20's. Almost every one of them has car ownership as their top priority. When they get their car it's drive, drive, drive.

    These are the ones that should be thinking about the environment, leading the charge, and it doesn't seem to be on their agenda at all.

  • Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 8,099 Mod ✭✭✭✭liamog


    I can't quite tell what other motive you would have for repeatedly making such clearly false claims that are in fact so bad your own posts refute them. The only thing that makes sense to me is that you have an interest in success of the oil industry and are shilling for them.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    Seriously, how many times have I mentioned 8 billion tons of coal, would it not be the coal industry I would be shilling for? (Which I'm not LOL)

    What false claims have I actually made anyway?

    Somebody posted research showing coal ev's might be just 10% better than ICE, do you accept this figure?



  • Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 8,099 Mod ✭✭✭✭liamog


    The coal industry isn't powering EVs in Ireland. The oil industry is powering combustion engine vehicles, the only reason to provide such false or exaggerated claims on EVs is to maintain the status quo of oil usage.

    A 10% improvement in emissions in the worse case is still an improvement. So yes that is a false claim. Never mind the fact every modern grid is transitioning to lower emission generation sources.

    You also claimed for Irish EV use "they need coal to move" despite having the knowledge to obtain screenshots from the Irish grid showing that coal is a very low percentage (7.8% at the time of your screenshot) of our grid generation.



  • Registered Users, Registered Users 2 Posts: 3,910 ✭✭✭...Ghost...


    What is being done?

    More than your glass is empty comments.

    Why is global coal consumption not falling?

    More people requires greater energy use. Coal is cheap and works for developing nations.

    Why is Moneypoint no longer being closed?

    It's still working and we still need the energy it produces while we transition. We are not ready. Plans change and timelines need to be moved sometimes.

    How is our million electric cars by 2030 looking?

    If you don't get the concept of a higher than expected target, I can't explain it to you. It's certainly better than no target by 2030.

    Why did we cut duty on petrol and diesel?

    Politicians like votes.

    Why do we keep missing our climate targets?

    Because they are set higher than we actually expect to achieve and so they should be. Hit the target and people get complacent.


    You're jumping all over the place man. Either stick with Global, or Ireland only figures. Otherwise it looks like you're trolling to me.

    Stay Free



  • Registered Users, Registered Users 2 Posts: 1,309 ✭✭✭MightyMunster


    It appears the young people you know are in the minority



    Yes you are missing something, 80% of our energy is from fossil fuels you say and then assume this is the same as the % powering our EVs.

    Except EVs aren't powered by petrol, diesel, turf, wood or home heating oil or anything else you put in your fireplace or fuel tank.

    What was the time and date that snapshot was taken?

    Its likely there was plenty of wind offshore even if there was extremely calm conditions over land.

    We need to hurry up and build the infrastructure to harness these resources. We're taking far too long

    Coal is being burned because that infrastructure exists.

    When we build the renewable infrastructure, then Coal won't be economically competitive anymore.

    Most countries did nowhere neear enough over the past 2 decades to prepare for the transition (Including Ireland)



  • Registered Users, Registered Users 2 Posts: 22,725 ✭✭✭✭Akrasia


    A BEV fueled entirely by Coal generated electricity is slightly better than ICE.

    This is the worst case scenario. In the real world, a BEV is likely to be charged at night when demand is low, so it's much more likely to be powered by gas, or renewable generated power (on a windy night, demand is lower than supply so wind can power almost the entire grid

    As renewables replace Coal and Gas power generation, the savings improve, while ICE cars will Always be powered by refined oil for their entire life cycle.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    Coal was 15.8% in my screenshot, so yes on that occasion we needed coal to move our EV's.

    If you take that 10% and assume a hypothetical scenario of dedicated coal plants to power EV's with on demand power then that 10% will be in losses in the system, excess supply etc. Its a marginal improvement at best, certainly not the game changer some elements are claiming it to be.

    Now in the real world I'm not disputing at all that grids are multi power source, EV's are great at soaking excess power at night, they are cleaner around cities and towns and ultimately provide a marginal improvement to the climate problem.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    I don't disagree with any of that at all except the second half of the last paragraph. We could have hydrogen combustion engines too.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    That snapshot was last week when we hit peak demand. Ideally battery power will come on in leaps and bounds so excess wind can be stored.



  • Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 8,099 Mod ✭✭✭✭liamog


    Sorry your right, I scrolled one post too many. Even in the hypothetical situation of building new coal stations to replace every oil driven car we still see a net improvement in emissions.

    Now you've nailed another fossil industry talking point. Hydrogen fuel is basically a dead end for automotive use due to the round trip inefficiency. It's very inefficient to use it in a combustion engine, even the more efficient fuel cell version doesn't hold up against BEVs. Hydrogen will likely be used on the grid for mutli day storage when the cost of green hydrogen is low that it makes sense to waste electricity creating it.

    Right now hydrogen is pushed by fossil companies because the only economical way to create it is via steam reformation of natural gas. It's a great delaying tactic which thankfully now has mostly run it's course.



  • Registered Users, Registered Users 2 Posts: 23,794 ✭✭✭✭ted1


    Well done, I could go back a week and pull up a day we are at 75% Renewables. It’s the annual report you need to look at.


    with little RES Coal is at only 15% that doesn’t suit your narrative..,,

    still much cleaner having no tailpipe emissions in the cities and towns



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    Or you could just look 2 posts below mine where somebody posted today's 70% renewables.

    Somebody yesterday posted our annual breakdown as well. Keep up.

    I don't dispute any of these graphs. But when the **** hit the fan last week and we hit our all time high electricity demand it was coal, oil and gas that kept the lights on.

    I don't dispute ev's give reduced tailpipe emissions in cities. Pity it's at the expense of people in places like La Guajira though.



  • Registered Users, Registered Users 2 Posts: 23,794 ✭✭✭✭ted1


    Yes. All that nasty coal you keep talking about. That’s being marginalised each year as our RES is increasing


    good if you to think of the Columbians are we getting coal from there ? We had been using Russian cosl, I haven’t got an update on where it’s being sourced now.

    but what about all those living in the Gulf of Mexico or war torn countries driving by oil extraction. No pity for them ? We are pushing towards RES. , EVs reduce fossil fuel reliance.

  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    Yes, as EV drivers it's the dirty little secret a lot of us, including you, know nothing about. Our little blood mine, 3/4 the size of county Dublin (think about that for a minute, then think about it again) kept our EVs moving last week.

    A few years ago, being super cool, we switched to Russian coal. But now we have quietly switched back, but you won't hear Eamon Ryan talk about that.

    By the way, last week, when we really needed power, our RES clocked in at a whopping 9%.



  • Registered Users, Registered Users 2 Posts: 23,794 ✭✭✭✭ted1


    There you go focusing on a snapshot.


    here is one from today 67% RES and 8% Coal.


    we’ve about 300 MWh of batteries coming online this month in Dublin and about 250 MW of PV. This will boost the RES on days there’s no wind


    Are you sure we’ve moved to Columbia?

    the next ship in to moneypoint is the : ZELLA OLDENDORFF which is coming from Newcastle Coalport in Australia..

    That snapshot, or similar, has been posted already. I'm not disputing it, you however want to bury your head in the sand when your EV is powered from our dirty little blood mine that you didn't even know about until I told you.

    On the days last week when we needed power, our renewables chumped in a stellar 9%.

    What will renewables deliver next winter with our batteries?

    In a severe winter will the batteries hold 3 months reserves like our dirty little blood mine holds down in Clare?



  • Registered Users, Registered Users 2 Posts: 22,725 ✭✭✭✭Akrasia


    Aaah.

    I'm Just gonna stand over here....



  • Registered Users, Registered Users 2 Posts: 26,089 ✭✭✭✭Strumms


    If our governments were in any way serious about the environment they’d have taken steps to provide proper far reaching green public transport infrastructure… we’ve had Green Party politicians in government in around 7 of the last 20 years. Plenty of lip service to the ideals but have delivered precious little to nothing apart from bleat on about bicycles in a country where it rains between 150-200 days a year. An island nation not exactly adverse to high winds and shabbily designed road infrastructure also.

    Dublin is the only Irish city in the entire country with a tram / light rail system…and for a city it’s size, only 2 lines which hardly scratches the surface of commuter needs.

    So we need not more EVs, non EVs on our already crowded roads, we need firstly fúcking public transportation that is fit for purpose, environmentally friendly, … fit for the population it’s required to serve…. Trams, metros etc… not all just for Dublin’s population although that needs to be a priority.



  • Registered Users, Registered Users 2 Posts: 23,794 ✭✭✭✭ted1


    https://www.seai.ie/publications/Energy-in-Ireland-2022.pdf

    page 132: coal accounted for only 9% of electricity generation usage for 12 months , stop letting on its the primary source.


    which is ironically the number you’re quoting for renewables last week and saying it’s insignificant


    renewables was 36%, 4 times that of coal.

    Dublin has less rain and less rainy days than Amsterdam, so is perfectly ok for cycling.

    Spending on active travel and public transport has never been higher. It's just started 30 years too late.



  • Registered Users, Registered Users 2 Posts: 2,232 ✭✭✭waterwelly


    Once again I don't dispute any of that.

    But people are on about transitioning to renewables as if we are almost there.

    Yet on the bad days our wind can produce just 9%, after how many years transitioning?



  • Registered Users, Registered Users 2 Posts: 23,794 ✭✭✭✭ted1


    36% of electricity isn’t a bad place.


    Lots of off shore in development aswell as Solar, aswell as green hydrogen.

    that number should increase steadily over the coming years.

    That number also means you are better off driving an BEV than an ICE



  • Moderators, Motoring & Transport Moderators, Regional East Moderators Posts: 8,099 Mod ✭✭✭✭liamog


    Mod Note: Any further claims that coal is a primary source on the Irish grid without a source showing it is the highest of any source will result in a thread ban



  • Registered Users, Registered Users 2 Posts: 645 ✭✭✭Killer K


    This seems very heavy handed. The poster in question is making reasonable arguments and there are enough counter arguments being made to provide balance and context. The poster isn't being in anyway abusive and boards is not an academic institution so not citing sources surely isn't an offence. Shutting down threads/ threatening to shut down threads/ banning people from threads does more damage to your cause than letting the debate move on. Perhaps you should step back from this thread as you are clearly over invested in it. Out of fairness, a player really shouldn't be refereeing a match they themselves are playing in.
