EVs are worse for the environment (the myth)



  • Moderators, Sports Moderators Posts: 17,888 Mod ✭✭✭✭slave1

    This myth again, EVs have reduced carbon footprint once in use and this quickly "betters" ICE cars, even better if EV charged off night rate in Ireland which can be predominantly Renewable and ultimately better with charging from home off PV

    Nope. You're way off with that one. The oil companies love you though, so there's that.

    ...Ghost (this feels spooky!) In this instance I was not replying to the OP (893bet) but to Kildare P (it's best that you get your facts right before shooting / SPOOKING😉 the messenger ! )

    Yes. And there are people who research this for a living. BEVs are what we need. Now. Buying an ICE if you can avoid it is the wrong move. There are untold millions being pumped into the media trying to muddy the waters. Don't add to it.

  • Registered Users Posts: 11,845 ✭✭✭✭KCross

    I'm not suggesting that ICE cars are better overall for the enviorment than E cars but the difference is so miniscule and in many cases it can be proven that buying a used ICE is better than a new E car .

    That's a straw man argument though. What happens when all the used ICE cars are gone?

    Of course, existing ICE cars should be kept running and not needlessly scrapped for new EV's (but no one is suggesting we do that).

    If you are buying a new car either way you need to compare like with like.... new ICE vs new EV and do the full well-wheel analysis for both... which has been done.

    Id concur on that carbon footprint issue.

    The attraction for the government is that the carbon footprint will be created in the countries mining and producing the vehicle

    There should be some bonus or incentive for car owners, whether ICE or EV to keep their cars for longer, instead ICE owners are penalised and are encouraged to scrap what are good cars with years of service left in them - a visit to any scrap yard will prove this. Main dealer scrappage schemes should be banned and instead, for a start, all cars over 10 years of age should be free of road tax once NCT is passed. Most cars if looked after have a lifespan of 15 to 25 years easy. Why buy yet another new suit and give away your lightly worn suit (which may just need a light dry cleaning) to the rag & bone man !🤣 The world's resources are finite.

    @monseiur adding to my request for numbers re the break even point, can you now provide sources for the short lifespan of batteries and the recycling difficulties, it seems your insight does not match the lived experience of many of the members of this forum. I'm beginning to think you may just be making this up as you go along.

    I see that you were not directly responding to the OP, but the post you were responding to was not asking for the "EV or ICE" question either. The poster was within the context of the thread and was broadly similar to the OP, hence the minor confusion.

    Not attacking you, but it does seem that when people have decided they want to go the EV route and are asking questions about what to buy and how to fit an EV into their lifestyle, there's always one or two posters who go out of their way to discourage the OP and others from going EV and it's almost always with outdated and incorrect information, like batteries needing replacement after a couple of years.

    Don't be scared. I'm a friendly Ghost (and a gun owner 😎 ).

    I do find it amazing how many people's EV knowledge seems to be based on the G-Wiz

  • Registered Users Posts: 578 ✭✭✭ddarcy

    So it’s is a debate, I’ll ask a few questions here.

    1. no one said a golf will have lower emissions. I think that’s implied. What’s the environmental cost CV of creating the golf / id3. You need to add that on to your 2.5 years above.
    2. a point which will be of annoyance. VW wants the IDs to have a 10-11 year lifespan (was told this when I got an ID3). A golf can easily have double that. So you need to count in manufacturing of an additional ID3 for comparison to the lifetime of a golf.
    3. really to annoy the green crowd here, but lowering emissions does not mean better for the environment. Republicans in the US were right when they said emissions would only be pushed to other countries for not signing the Paris climate accord.

    to give an example of this. Ireland will reduce methane by 10% and the greenies will lap it up and pat themselves on the back convincing themselves they’re doing their part.

    But supermarkets with incredibly low waste (think fractions of 1pct) will be expanding offers of meat products. So how are they going to do this? Well we signed an agreement with Brazil to supply meat. So take a farting cow in Leitrim. Is it better to keep it in Leitrim or to burn down the Amazon rainforest as there’s no farmland in Brazil and rear it there along with shipping it back to Europe? This is how ireland and Europe is dealing with climate change (basically making it worse). E cars are in this as well.

    hiwever I believe in the phrase you can’t make a perfect omelette without braking an egg. So we don’t have the solution yet but this is a step in the right direction. There are still issues to overcome though.

  • Registered Users Posts: 9,955 ✭✭✭the_amazing_raisin

    Actually I heard that cows emit more methane from burping than farting

    Just to derail this conversation further 🤣

    Don’t disagree with you on getting free of oil and gas. We have wind, hydro, solar etc and really should have more renewable than we have now.

    the cow example was to show in real life how we are dealing with things. We lower emissions but in actuality pass them on and make them worse.

    for ecars it would be interesting to see the breakdown by year of cars sold and are still on the road. That’ll tell us their true longevity. Obviously we’re dealing with low numbers to start.

    one last one for ecars , how many companies are marketing helping global climate change? None, they just market zero emissions, reducing emissions, etc. why? They just make you think that and Because especially in the US they’ll get done for false advertising. That’s not slap on the wrist stuff, the could get class action lawsuits against them (see VW still getting wrung up for dieselgate). We’ve been manipulated into thinking lowering emissions is all that needs to be done, when in actuality we’re making things worse in almost all instances.

    Electronic cars are brilliant for air and noise pollution in the towns and city's.

    But are they really that more environmentally friendly? I Very doubt it in my opinion.

    If you wanna save the environment walk or cycle.

    Coincidental or maybe not the last podcast of fully charged is on the same subject. How the hec after 12 years we keep repeating the same myths spewed by some nuts without any facts behind, just to fits ones agenda. It might be boring for some

    @PaulRyan97 nice work in quantifying the costs. When looking at carbon footprint, you're missing the greenhouse gases produced in the process of extraction, transport and refining. The well-to-wheels as described in this article (pay-walled but any good library in IE will help). Data is hard to find, complex to quantify but it exists and it is significant. That needs to be added to have a true comparison as at the moment you use the grid data for the EVs but not well-to-wheels for ICEs. How much CO2 is produced for the 1l of petrol from the crude extraction, transport across the seas, refining and pumping it into the tank. Another trap that we are falling into since 2008, is to think in terms of CO2 only, when burning petrol/fuel in engines create much more heavy and toxic gases which we call GHG to sound a bit less harmful.

    One point I'd like to make is that irrespective of the energy source, the electric motors are proven to be more efficient than their thermal counterparts. In the above comparison we speak of 49.8 kWh/100km for Golf vs 15.6 kWh/100km, so basically x3. The increased access to renewable energy sources and advances in energy storage put the ICE in economic disadvantage. There are still problems but that is progress.

    Not going into the farming GHG as it will dilute the discussion.

  • Registered Users Posts: 390 ✭✭PaulRyan97

    @innrain Of course yes, well to wheel should be absolutely considered. I took a sandbox approach here in only calculating carbon footprint based on the energy used by each car, ignoring the carbon footprint of actually getting that energy where it needs to be.

    I agree, the data is incredibly difficult to quantify however it is clear that the carbon intensity of extracting, refining and transporting petrol is several orders of magnitude is far greater than the mix of fuels we currently use in our grid. Also, it's footprint is unlikely to shrink in the coming decade, while our electricity grid will continue to lower its carbon intensity, further widening the gap. The current target is 100g/kWh by 2030 which would give a g/km output of just 16g and lower the annual emissions to just 234kg. That would mean a breakeven point (assuming that production emissions have somehow not dropped) of about 1.8 years.

    The best analysis I've seen was conducted by Volvo, they did a full Carbon footprint report comparing the C40 recharge vs the XC40 over a mileage of 200,000km

    Their LCA showed that a C40 operated on the EU grid would have a lifetime emissions 42 tonnes of CO2 versus the XC40 of 59 tonnes.

    The most notable takeaway I found was the the use phase phase emission reduced by 27 tonnes, versus a manufacturing emissions of 26.4 tonnes. Taken to the extreme this means the emission of producing an XC40 and immediately scrapping it to replace with a C40 recharge would result in 59.2 tonnes of CO2 versus just using an XC40 for 200,000 with 59 tonnes.

  • Moderators, Sports Moderators Posts: 17,888 Mod ✭✭✭✭slave1

    That's actually interesting, I know GIGA in the US has massive PV for the production facility, I wonder does either Berlin or Shanghai have that advantage also to bring down Tesla carbon emission at manufacturing stage?

    Ireland would be different (*from a strict Ireland only perspective) as the phases up to end of manufacturing emit in other parts of the world and we have great renewables at off peak rate.

    At a micro level, those charging off home PV would be bringing things right down, finances aside, all roofs in the country should be plastered in PV to reduce carbon footprint

    You'd also imagine that battery manufacturing/processing impact would be less for battery chemistry like LFP ones (e.g. shipping in the base model 3). No nickel or cobalt which have a fairly hefty environmental impact. Not sure the impact of solid state batteries in the future too.

    Every claim made in this video is backed up by citing their sources. Well worth a look if you think EVs are worse for the environment.
