    that’s the question I asked though!

    Have you any thoughts on this?

    So you're saying it's BS and has been based on a single cat owners own calculations? You sure about that?

    Some interesting reports coming out of the presentations made to the Oireachtas Committee on Environment and Climate Action today 

    Some of the main points raised (covered across multiple articles below)

    LNG Supplies & LNG Terminal

    • Building new gas terminals would cost householders more in energy bills long term
    • Increasing Irelands reliance on fossil fuels like natural gas or liquified natural gas (LNG) would also increase the economy’s exposure to energy price volatility
    • Massive construction and running costs would be passed on to householders by private operators
    • Any state-owned facility would face similar problems and need subsidies or levies funded by ordinary billpayers
    • Europe has enough LNG terminals and building one in Ireland would take years
    • Given the useful lifespan of an LNG terminal is 30-40 years, it is feasible that Irish gas customers or taxpayers could still be paying for the LNG terminal in 2062
    • Given Ireland’s access to piped gas from the UK, an Irish LNG terminal would be a last resort. So we can expect very low utilisation rates of such facility
    • Many LNG projects across Europe have required “operational aid”, not just investment subsidies. One such example is a Croatian terminal on the island of Krk. In addition to securing public subsidies that covered 86% of the investment costs, the operators were guaranteed a security of supply levy — essentially an LNG levy to be placed on gas customers’ bills by Croatian gas grid operator. The levy would cover any shortfall in revenue from the running of the terminal.

    Wind/Solar etc

    • Ireland can generate up to 5,000 megawatts by wind, but on "quiet days" only a fraction of that is delivered
    • Energy policy is all driving towards fulfilling net zero carbon emissions, by 2050
    • The CRU is accelerating the deployment of green energy in light of the "shocking" Russian invasion of Ukraine.
    • Ms McEvilly pushed for "an acceleration" of the review of the planning process, which has a direct bearing on the delivery of new energy projects
    • 745,000 smart meters have been installed in Irish homes to date

    Ok.

    So can you tell me how people are expected to pay the repayments on a loan for this?

    Pretty fundamental question seen as money is a finite resource.



  • Moderators, Science, Health & Environment Moderators Posts: 19,668 Mod ✭✭✭✭Sam Russell


    'People' is 'everybody', but we do not need 'everybody' to raise their homes to BER=B3 or higher, but those that can should, whether by loans or from their own resources. Not everybody is desperately poor living from week to week, but some are. Those that qualify will get the required upgrades at zero cost to themselves - eventually.

    Those that have a drafty uninsulated home with a BER=F or G will get 80% grants to fix the uninsulated attic, and further grants to improve other aspects that will lift the BER to C and perhaps B if they are lucky.

    With suitable advice, all the low hanging solutions will be cost effective in reducing their energy bills and so reducing their carbon footprint. It all does not need doing immediately - besides we need to train enough workers to do this programme of retrofits.



  • Registered Users Posts: 10,376 ✭✭✭✭tom1ie


    Problem is when you introduce a grant to get something done, the market reacts and the price increases.

    For example attic insulation costs €1000,

    government introduce grant of 50%= €500,

    attic insulation price increases to €1500.

    This is happening.

    I would also say there a sizeable chunk of the population (the squeezed middle) who won’t qualify for grants and don’t have money lying around to improve windows or doors or reduce drafts.

    After the relatively cheap cost of upgrading attic insulation you are into costly amounts that a loan would be required for.

    The loan obviously requires monthly repayments which a large proportion of people just don’t have.

    Insulation increases are linked to the increases in oil & gas prices according to this

    Also your sums are not complete

    50% of 1,000 is 500, yes, but if the price is 1500, then 50% is 750

    The point I’m making is that if the government introduce a grant for a certain % the market just adds that grant to the price.

    Its a sad fact but that’s just the way the market works.

    Also insulation costs were increasing long before the current oil spike.



  • Posts: 0 [Deleted User]


    Would that not mean those price increases pre-date the retrofit program?

    Just not seeing your chicken and egg scenario being played out in reality. Maybe I'm missing something but I don't think so



  • Registered Users Posts: 10,376 ✭✭✭✭tom1ie


    Yeah you are missing something.

    When a grant is introduced that just gets absorbed by the materials provider plus the installer etc.

    The person paying for the product doesn’t really see any benefit in the grant.

    Purely anecdotal I’ll admit but there ya go.



  • Registered Users Posts: 232 ✭✭specialbyte


    Oh god that whole twitter thread is just full of misleading statistics like "Wind turbines generate electricity ~30% of the time & solar panels ~20%." that the fossil fuel industry have been using for decades to attempt to discredit renewables.

    The graph source is also from a niche American lobbying organisation. Rather than from a highly respected organisation like Lazard's who have been producing a Levelised Cost of Energy (LCOE) Report for ~15 years: https://www.lazard.com/perspective/levelized-cost-of-energy-levelized-cost-of-storage-and-levelized-cost-of-hydrogen/

    Lazard's have very different numbers that don't produce "nuclear is the silver bullet" kind of answer that Gitt's graph suggests.

    Edit: Only noticed now that the graph is comparing *existing* nuclear versus *new* solar. Haha. This is like how to lie with statistics 101.

    Yup, got a chuckle out of that too when I spotted it, hilarious stuff

    It's not a general rule that markets work that way. They can behave that way but only if there's a completely inelastic supply. The cost of the insulating materials is set internationally, so is effectively fixed and is not affected by Irish demand. The aspect that is affected by Irish demand is the supply of labour/installers. But there's a range here depending on the skills required - while you're assuming behavior at then extreme.

    Fitting attic insulation is effectively unskilled labour so supply should be completely elastic. There may be other forms of insulation installation which require rare specialist skills where supply will respond much more slowly. But even in this case, we're not talking about lawyers and the like (where there are artificial/legal constraints on entry into the profession), so eventually supply will grow to respond.

    Coincidentally - after reading a bit more about heat pumps, look at the number of tradesmen offering to fit heat pumps in the UK - it has exploded in the last years - responding to UK government grants to replace gas boilers.



  • Registered Users Posts: 1,135 ✭✭✭gjim


    We had our own favourite nuclear booster on this thread trying to pull the same trick - quoting LCOE for nuclear but leaving out the word "existing".

    Given nuclear costs are about 60%/40% capex/opex, this allowed him to quote an LCOE of much less than half of the true cost.

    But if they want to play that game, I'd be very happy to do so. The LCOE of wind turbines and solar PV panels ignoring the capital costs is even more impressive - it's almost ZERO.



  • Registered Users Posts: 13,902 ✭✭✭✭josip


    I think what you might be referring to is the scenario where the grant-compliant companies charge more than the non-grant compliant companies, usually by a similar amount to the grant, in order to cover the additional admin cost of the grant paperwork.

    OT, but I had one case of a builder quoting for a bathroom renovation. For the exact same work/materials, to do it the grant-compliant way would have cost more than the grant.

    The scale of this deal between Germany and Australia for green hydrogen shows why we need to get going on this ourselves

    5million tonnes of green hydrogen per year

    50 billion setup costs

    200GW of wind and solar, enough to power the UK

    Look the fact is they do behave that way.

    Ask an installer how much PV costs and they’ll give you a price which includes claiming the grant and then they’ll give you a cash price.

    The price including the grant would have been cheaper before the grant was introduced.

    This is the market reacting.

    Same happens in other industries.

    Introduce a rent supplement, guess what the minimum cost of rent increases.

    Its just the way it works.



  • Registered Users Posts: 1,135 ✭✭✭gjim


    Tom1ie - I'm not disagreeing with everything you say - just pointing out that the effect you describe requires an inelastic supply. Personally, I strongly oppose government grants where the supply is inelastic - e.g. for buying houses and the like - the money goes straight into the pocket of vendors and just burdens everyone else with higher prices so in the end, it just benefits current owners and developers and not struggling purchasers. This is well understood by economists.

    Rent supplements are another example - there's a chronic inelasticity of supply because of the speed at which we're building homes is barely meeting latent demand never mind the growth in demand. Economic theory predicts the exact behavior you describe. For property it's a well known phenomena globally - prices (whether buying or renting) track affordability; lower interest rates, increasing incomes, the availability of grants, etc. all just benefit vendors.

    But if supply is elastic and can quickly respond to demand, then you don't see this effect. For example, the car scrappage scheme didn't push up prices of new cars for people not using the scheme because the supply is elastic - dealers can just import more cars - again following economic theory.

    I'm really not sure about the PV installation story - do you have direct experience? And I'm not sure you aren't mixing up two separate effects - in the past this was a way to allow the installer to avoid tax and applies for any sort of work including unskilled labouring regardless of there being a grant involved or not. But if it is true, and it's not related to tax avoidance, then it suggests that at the moment, there aren't enough PV installers and that not enough people are entering the business to satisfy any increase in supply.

    Anyway this is getting wildly off-topic and might be better discussed in an economics thread.



  • Moderators, Science, Health & Environment Moderators Posts: 19,668 Mod ✭✭✭✭Sam Russell


    Mod: Can we leave the grant - raising the prices argument. The point is made - there is evidence that this occurs - it is prevalent, but it is not universal.



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


    €50 K will not be recouped in energy savings over most people's life times, particularly if you factor in maintainance and equipment replacement.

    It's very reasonable to make such systems mandatory for new builds but it's not appropriate to try and force them on existing housing stock. I recently sold my holiday home and the BER rating was G.



  • Registered Users Posts: 10,376 ✭✭✭✭tom1ie


    So in other words it just doesn’t make financial sense to deep retrofit existing stock.

    By all means insulation and even new windows etc but after that, financially, there’s not a whole lotta sense.



  • Registered Users Posts: 13,902 ✭✭✭✭josip


    It depends on your outlook on life and society I think.

    If your perspective is only on self, then undoubtedly there's no point going beyond a certain point for some existing stock as the payback will exceed the owners' lifetimes.

    If you have a multi-generational perspective, then it does make sense to retrofit beyond that, since your next of kin will also benefit from having a better insulated house. Either to live in or a higher resale value.

    Governements are also like people. Some of them prioritise multi-generational considerations when making decisions. Other, more populist regimes, only focus on their own lifetime in power.

    We're not great at focusing on the long-term in Ireland, eg the Celtic Tiger property bubble. But we do show from time to time that we can look beyond the next 5 years for Energy Infrastructure, eg. Ardnacrusha (the largest hydroelectric scheme in the world until the Hoover dam), Turlough Hill, Celtic Interconnector. We can do similar with offshore wind and catch up for the last 20 years that have been effectively lost.

    Hopefully we won't repeat the mistake by being slow to invest in and develop green hydrogen. It does at the moment appear to be the only practical companion to excess wind in Ireland given our lack of suitable sites for pumped hydro.



  • Registered Users Posts: 10,376 ✭✭✭✭tom1ie


    Fully agree with you on the green hydrogen.

    I think it’s an emerging market we should be getting in on.

    I just hope the whole industry doesn’t get held up in policy changes and planning delays for decades.



  • Moderators, Science, Health & Environment Moderators Posts: 19,668 Mod ✭✭✭✭Sam Russell


    I think that people are willing to invest insane amounts in refurbishing homes about once per 20 years or so. This includes extensions, or internal alterations like new kitchens or bathrooms.

    It is reasonable to take such activity as an opportunity to improve the thermal performance of a property including upgrading the insulation and heating system. Generally, deep refurbs are undertaken at such times, and including new windows, new heating system, better insulation - all are considered when grants are available - and those grants can offset much of the addition costs.

    It can be cheaper to build a new A rated home than a lower rated home because there is no heating system needed. It is a pity that the call for better insulated homes was not heeded in the 1970s or the 1980s or the 1990s.



  • Registered Users Posts: 13,902 ✭✭✭✭josip


    Are you sure about no heating system needed Sam? Assuming you mean Passive Haus when you say A-rated, even those houses have a heating system built into MHRV. Without a heating system, if you go away for a week or 10 days at Christmas, you're going to need some way of bringing the temp back up. It would take a lot of body heat to do that.

    Well, I heard someone claim that passive houses could dispense with a heating system, but you are right that prolonged absence of people could leave a property quite cold in winter.

    However, good design would get heat gain from solar, plus the temperature would tend towards the average over the 24 hours - not average over night. Orientation re sun is also important - with large windows towards south and small or none towards north. Add in heat recovery ventilation, and you might get away with no heating system - but even if you needed one, it would be minimal.

    But such claims might be taken with a pinch of salt unless it relates to specific homes designed to be fully passive. Such design requires high level of detail in not only design but also construction.
