    Dreading the next budget, all a ply to dramatically increase motor tax and bump up tax on fuel also. The lucrative cc tax pre 2008 is weakening and the government have to replace it.

    Tolls might go up too.

    Government talking garbage as usual that will cost the tax payers billions

    Hey this is Leo the lovely we are talking about.
    Lots of fluff but no real costings and when someone does come up with figures, it comes back as billions.

    But hey they will find the money and there will be no cuts to anything else.

    I guess I should wait another half dozen years before thinking about changing to a BEV ........ from
    https://www.dccae.gov.ie/documents/Climate%20Action%20Plan%202019.pdf
    Page 91
    By the middle of the 2020s EVs will reach TCO-parity with diesel and petrol engines. This means that when a consumer factors in both up-front cost and ongoing running cost, it will be as cheap to have an EV as a petrol/ diesel vehicle.

    What I saw yesterday was a Taxation plan not a climate plan, no plan to deal with Agri (45% CO2 contributor) , air transport and industrial emissions.

    FG plan to scare people into electric cars and raise property taxes.

    This house won't be voting for Greens or Blue shirts in any general election.

    Climate change is the great gravy train for Governments. Just a great excuse to collect revenue.

    I'm not going to stop eating beef, it has to come from somewhere, if not from Ireland it will come on filthy oil burning ships from somewhere else and God knows what the quality of it will be but oh the Government won't care because they can boast about how Ireland's Farming community produce less Co2.

    The Government would be far better off to give farmers grants to plant real hardwood forest, proper forest not tiny woods scattered here and there, get other farmers to plant forest and merge on different lands with other farmers to make proper big forest people can actually enjoy.

    Ireland has shocking little real natural forest and most of what's there is grown to cut down and crappy pine trees, make these new forests protected and turned into parks with real native hardwood trees. There offsets Co2 if people are so concerned but the benefit would be having real forests that are protected for People to enjoy.

    Air travel via fossil fuels can't be avoided, there is no alternative and none on the radar.

    Honestly i think politicians live in a complete bubble. A half decent EV costs what 30k euro?? but yet you can buy a perfectly good car that will last for another 10 years for 3k euro. Do they think money grows on trees or something.

    Yes. In some other countries it's much earlier. In Norway it's only 5 years away. And only 3 years away for taxis.



    EVs are largely charged at night. Up to 75% of Ireland's night time electricity supply is from wind. This percentage increases every year. Should be up to 100% within the next few years (on a windy night of course)

    Ireland has used almost zero coal to generate electricity for nearly a year now...

    Any comparisons with Norway are completely bogus: they have a surplus of (hydro) electricity. Their electricity is only 5c/unit. They subsidise EV on the back of a cash pile earned on the back of - shock: oil......which has put them in the envious position of the world's largest cash pile.

    the incentives for EV are now being unwound with what's nicknamed 'the Tesla tax'
    EV incentive's of low tax, use of bus lanes, free parking, tax credits, free ferries etc have lead to the pendulum swinging too far....

    By all means buy EV if it works for you, but comparing the Irish and Norwegian economies is bonkers.

    ESB Networks installs all night rate meters

    It is completely free to get one installed. Your day rate will go up by about 1c from say 17c to 18c per kWh. Your night rate will be about 8c per kWh and your standing charge will go up by about €50 per year

    For an average household, with no electric showers, no electric heat pump and no electric car, this is about break even (so it won't save you anything, but it won't cost you anything either. But it will save you money to put on your dishwasher / washing machine etc on a timer to run at night). If you have one of the above, you will save a small fortune.

But seriously in what legal/safe driving situation can you actually use all 300BHP? Could you use them if perhaps you are in too high a gear when overtaking? But that wouldn't work 'coz you'd be well over the speed limit if using all those horses in a high gear.

    A complete diesel car ban in our cities can't come quick enough. Several other countries have already implemented it, hopefully we will be next.



    That's in new houses though. They are so well insulated that you don't need to have a powerful fossil fuel boiler any more. A more efficient, low power (and zero emissions) electric heat pump will do. By then these will be smart enough to mostly run when electricity production is fully renewable (zero emissions again) and as such very cheap (just a few cent per kWh)

    There's no such thing as a 'zero emissions' heat pump. The emissions are in Moneypoint, that's all. Its shell games [sic]

    Moneypoint, the only coal power plant in this country, hasn't been running for quite some time. Thankfully. Ireland no longer burns coal for electricity.

    Ireland's mix at this point is mostly gas, with a very significant contribution from wind. At times wind provides 75% of our electricity. We need to get more wind, and we seriously need to get a lot of solar (we have almost none)

    Hp dictates the top speed, torque is responsible for acceleration.

    Electric cars generally have a higher than average amount of torque so accelerate quickly.

    +1

    Not only that, the crucial thing about the torque in electric cars is that it is available at idle.

    The torque at idle in my 118bhp EV is about the same as what my 320bhp 5l V8 petrol Porsche had. So the initial acceleration away from the traffic light would have been about the same, were it not from the losses in the automatic gearbox of the Porsche

    In comparison, modern cars with small engines and turbo chargers are very lame in their initial acceleration because they have tiny torque until they have overcome the time lag before their turbo charger produces significant torque. Their torque at idle is pretty pathetic. Same as the bhp of my EV, which indeed doesn't matter much if you don't want to drive over 170km/h :p

    If it's not environmentally sustainable, it has to change. Jobs and money will all be a bit academic if the country becomes uninhabitable.
    But have they thought how people in apartment blocks and townhouses will manage where they don't have parking spot outside their front door ?
    I live in an apartment, I have an assigned parking space and I have power in the storage unit behind my space (that is connected to my meter, so I pay) which I use to charge my PHEV.

    Anyone who has assigned parking spaces could theoretically get a charger installed - it doesn't matter how far it is from their home, it can be done (my meter is closer to my parking space than my apartment, for example). The problem is with management companies who may not agree with this - there needs to be legislation in place that gives people the right to get a EV charging point installed.
    How much will it cost to put charge points in apartment block parking spaces and who would pay for it ?
    Right now, the car owner pays, but there are grants. It may cost slightly more than a household installation, depending on distance from the meter/consumer unit.
    And they have to be ones that only the parking spot holder would have keyed access to so not your usual bog standard cheap solution.
    Locks are available for standard EV charging points.

    Most people don't need anywhere near 56 kWh every day.

    The national average distance to work is 15 km (2016 Census). Using a pessimistic efficiency of 20 kWh/100km (most EVs are more efficient than this), that would be 6 kWh required for a round trip. That's similar to running a tumble dryer for 2-3 hours.

    I can do my commute (14 km round trip) using less than 3 kWh. I'm using closer to 56 kWh per month, not day!
    Just wondering here, where do hybrids stand in the grand scheme of things ?
    Non-plug-in petrol hybrids make a petrol engine a lot more efficient, close to or surpassing equivalent diesels while being better in terms of emissions (NOx, particulates, etc.). But there's no long term future in these - the ICE has to go. Plug-in hybrids are better again, but still just a transitionary technology.

    I moved to a plug-in hybrid 4 years ago, and the running costs are less than half than my previous diesel. It doesn't make up for the cost of the car (about €19k for a 3 year old Prius Plug-in at the time), but it was the budget I had set for a replacement car anyway. The EVs on the market at the time within my budget didn't suit me - maybe they will next time...

    No it doesn't..

    hp is dependent on Torque and engine revs. In an electric car peak HP will allways correspond with peak RPM which will be top speed but top speed HP in that case top speed dictates HP not the other way round. for example, if you made no change to the motors or drive but improved aerodynamics or Tyre resistance then top speed would increase, and as a result Hp. (but if you ran this on a rolling road then the limit would be max motor RPM)

    In an electric car torque is a straight horizontal line and HP would be a straight lien with the lowest point at 0rpm and highest point at highest rpm.

    In an ICE engine torque isn't a straight line and varies at different points in the rev range normally dropping off at higher RPM's so completely different power curve..

    1stly do you have any idea of the power demand of a heat pump and the surface area of solar panels required to power just 1.

    2ndly you do realise that maximum demand for heat doesn't exactly match with peak solar availability.

    I will freely admit that this could be addressed by a sufficiently distributed grid (interconnected with equatorial or desert based solar farms) and sufficient storage (not a powerwall) but none of that is available now or in the immediate future.


    So I repeat my earlier comment, a modern demand led electricity system cannot depend on wind (or solar) without a dramatic (and I mean game changing in the multi Twh rage) increase in interconnected power storage

    Averaged over an entire year, there is potentially 6 months of sunlight and 6 months of darkness. Factor in the significant cloud cover in this country and you get only 23% of a year having sunlight. Heating is needed mostly in winter and at night, when there isn't any solar energy to power a heat pump.

    If there was enough sunlight to warm houses, Ireland's average annual temperature wouldn't be 10°C. Trying to heat a house via solar in this country is as practical as flying by pulling vertically on your shoelaces.

    There's a whole section on agriculture and 35 action points and air is rolled up into transport in general. You can avoid those parties as much as you want but pretty much any of the rest of them has the same type of view. BTW this post is a very good example of the challenges that are involved in change management!

    Possibly, but I doubt the two countries I have in mind have a general populace that will stomach the hefty coercive taxation this country seems to tolerate so easily. They already have generally lower rates of taxation so even if they introduced the exact same measures, there would still be a beneficial differential

    To be clear, I had already intended to emigrate due to the the tax regime here, this new stuff just has me affirming my existing decision.

    Heat pumps dont make heat, the move it from one place to another (i.e. a pump)

    A house with a heat pump will be a very highly rated house, probably A.
    An A rated house takes very little to heat it.

    Solar energy gathered during the day can be stored for use at night, irrespective of whether this in batteries in the home or at the grid level.

    Your final sentence shows your ignorance on the subject. No one is advocating using solar energy to heat a house, its using solar energy to run an electrical appliance.

    What size batteries are you proposing ??

    Or what level and type of grid base storage ??

    Soundbites are fine and dandy but reality isn't quite so nicely packaged...

    I repeat for the third time. You cannot build a modern demand led power generation and distribution system based on wind and solar unless you connect vast quantities (multi Twh) of storage..

    That is why every wind farm in Ireland is backed up with hugely inefficient single cycle gas turbine plants.

    The reality *today* isn't so nicely packaged, but we are talking about in 10 years time.

    Go back ten years and look how tech in *every* arena has advanced and then try to tell me that the same wont happen around energy production and storage.

    Indeed. But that can be done with tech that's 100 years old (pump up water with solar / wind, let the water fall when there's no sun or wind), we already have a tiny one of these (Turlough Hill that's been running for the guts of 50 years now)

    I know a heat pump doesn't heat, I just went for brevity. There isn't enough sunlight to generate the electricity to run a heat pump for most of a year, at the times it is most needed, given you need about 2.6 MW a year to run one.

    The grid doesn't store electricity unless you want to flood some large scenic valleys. The idea that feeding excess domestic solar energy into a grid is 'storage' is ridiculous.

    Most of the houses and accommodation that will ever exist in this country, already exist. Useless blather about passive houses and new houses is just as much of a eco-ego stroking sop as thinking the grid stores energy.

    It is obvious that you are trolling or you genuinely do not have a notion.

    Maybe this coming emphasis on electricity will get this idea off the ground

    But there is more than needed during the other half of the year, right?

    Better tell the lads in Turlough Hill.

    Indeed they do. And they are all going to get renovated to bring them up to standards over the next few decades.
