Net Zero - its over.

[Dave645]

Fossil fuels are a ready made resource that can then be manufactured from.

Renewables require resources to be MADE BEFORE similar or the same Manufactured process can be used.

There will be more Air Pollution from Renewables for Chemical processes - it's unavoidable.

Regardless, pollution will continue with EVs because break pads, clutches, tyres, waste fibres, rubbish, bearings & environmental road dust will still exist. Everything wears.

It will be interesting to see if this Particulates ill health is true or not, statistics haven't shown any link to dementia & worklife for example. Dementia is a modern disease which didn't supposedly occur when our ancestors worked close to heavy industry. People do wonder if it's linked to some Foods we eat.

EV’s don’t have clutches they use brake pads far less and with efficient driving nearly zero brake use, and the majority of road dust is brake dust.

and arguing over health is very low, anyone losing a child to asthma Aggravated by air pollution will not like your devaluing of there child’s life. I am starting to think your a Sociopath.

you have no concern for the welfare of others. Especially if it gets in the way of your agenda.

I am a realist I know to completely move away from fossil fuels will take a long time maybe past the end of this century but that’s not to say the goal is not a worthy one.

 

[BrianV]

I know the savings will be greater than the cost, the reduction in deaths and general health benifits alone is a greater saving than the cost.
Something you keep losing sight of very conveniently.

yes you can recycle steel and make new without fossil fuels, there are lots of things we can do differently and do without fossil fuels, it’s only when we look for them we find them, from the looks of things finding an alternative to our addiction to plastics would also be a good thing as it’s now in our food chain.
Micro plastics are seemingly everywhere, we had packaging well before plastic was commonly used.

the fact you think the transition is expensive shows how little you value life and health of the millions effected by our use of fossil fuels every year.

having a child die from asthma aggravated by air pollution is not something anyone wants to experience.
Yet a lot do.

and the final benifit it will hopefully slow climate change and let our civilisation continue, so not trigger food shortages due to extreme weather etc etc. no one ever said the higher average temps would be our down fall it’s the effects on our environment. Effecting our ability to farm and grow crops.
The reduction in farmable land area etc etc.

your very short sighted to the values of renewable energy and our transition to sustainable.
Theare many and massive, and there are so few benifits to saying as we are, until fossil fuels dwindle already the uk has become a net importer of fossil fuels our production has fallen from its production high points, and they are only set to fall
When you rely on extracted and burned you have to keep replacing it, when you go renewable that extracted element reduces not increases.

I built myself a passive house the cost was greater than just a standard house the detailing was hard to do and elements needed pushed up the price to build it, but I also knew that once done the saving would repay me which they have, my heating is on only on, 4 months of the year, and I only use electric and my bills are less than an average house that’s half the size. This increased costs were mostly windows and doors and execution of detailing air tightness etc and the required heat recovery to allow for air tight. So maybe £10k extra labour and materials.
I save £2k a year on average for my property size to heat it etc, so it was well worth the up front cost. it’s the same for renewable energy and sustainable transition.
It’s well worth it when you factor in all the benefits.

I do always wonder on this insistence of air tightness for efficiency, surely if you are relying on this during the winter period when coughs & flues are everywhere it cannot be healthy & if you open a window for fresh air all that gain flies out said window.

 

[Dave645]

So you are safe from abnormally low barometric air pressures?

No lol, air tight still requires a 50% air volume change every hour and the pressures in the house is what it is out side.
Air tight is not air tight it’s very air tight, but not air tight.
An average house has to be a 10 on the airtight scale the building control test for, a passive house has to be under 0.6.
the best the building control had tested before mine was a one bed flat that got a 3 my house got a 1 so just over passive cert standard but still 10 times better than the average house.

and all my air is filtered as it comes into my house for those with allergies it’s a nice extra.
Air tight only comes into play in the cold months where the energy savings are massive.
I am free to have windows open any other time if I wish.
The heat recovery is 95% efficient at recovering heat from the air leaving my home via the heat recovery unit.
So half the volume of my house every hour and I recover 95% of the heat I would normally lose to ventilation. From say trickle vents open windows etc etc.
And my home is one temp 24/7 as the heat recovery helps with that and my heating in the deep winter end of November to around March time. When just lighting my wood burner for a few hours every few days is all the house needs. Before I put my GSHP on. When the days get short so solar gain from the sun on my windows is reduced.

It’s actully well ventilated has an air volume change every 2 hours, and all the air is filtered.
Even when all the doors and windows are shut.
Net effect I am nice and warm for very little energy.
My heat recovery ventilation system is linked to a air heat exchange ground pipe, which is 50 metres long and is 2.5 meters deep in the ground where temps are stable at about 12c so even on the coldest night the air coming into my house is 12c then has the heat recovery units add in 95% of what I would lose from pure venting the air so net loses are small even when the volume of air in my house is changed every 2 hours.
Upfront costs over net savings. You cannot be short sighted in life or you miss out. Always play the long game.it’s nearly always the best bet.

if you chose to open a window that yours to make, my heat recovery units has worked for 12 years so far, the only maintainace is cleaning the air filters and replacing them every 5 years or so.
The cost to run it is more than offset by the savings it makes. And I get fresh filtered air and a warm house.

You've done well to put that into a 200 year old house to be fair as getting them airtight enough is difficult

 

[Y Fan Wen]

You really do talk a lot of nonsense, everything is wonderful if only we do what we’re told and the promise of jam tomorrow when the truth is that energy from renewables will be more expensive than fossil fuels ever was they certainly are at the moment so if you think that renewables will get cheaper you are quite simply delusional.

Last July 2022 auction for offshore wind CfDs averaged £37.35 per megawatt hour on a total of 7GW. That's 3.7 pence per unit. So yes, it looks like I am deluded.

Germany has spent more money at a national level on renewables than any other European country and yet has had the most expensive electricity in Europe for years.

Explain to me why consumers are still being forked for 22p a unit when people are selling it wholesale for 3.7 pence? That's 10 times the return.

I had to ask but with this air-tight house you have, don't you worry about hypoxia?

 

[Kiwi Pete]

That ship may have sailed

 

[bluebell]

Getting insulation, ventilation in a house, bedroom is difficult? On the one hand if the building/room is sealed to well? the room, building cant "breath" and neither can you? I like to have my bedroom window open at night in the summer hot days? Its like having a building, or car/tractor, come to think about it, perfectly sealed to stop dust, then having to have the airconditioning at full blast to "cool" the inside, a "happy" medium is needed? Another "parodox" of modern life in homes, is the total reliance of one "heat" source, be it, electric, gas, without the "old fashioned" standby of an "open" fire, like last winter, which we were lucky was not to cold? With the massive increase of gas to heat the home? We have masses of waste, wood, we cleared just a small piece, there must be enough wood, waste to heat a few homes for a few years, plus the exercise is "good" for you in the chopping up of the other wise "waste" material?

 

[Dave645]

I had to ask but with this air-tight house you have, don't you worry about hypoxia?

No, for 2 reasons even an air tight is not air tight, 0.6 for passive and the heat recovery runs 24/7 and has done for 15 years without issue.

my house is actually better ventilated than most are, because how many people shut the window trickle vents in winter. Cover up air bricks etc.

the building regs
In both England and Wales, the maximum permitted air permeability for a new dwelling has been reduced from 10 m3/hr.m2 to 8 m3/hr.m2 @50Pa
So a 1 or a 0.6 results required for passive is not air tight building code was a 10 at the time of my test, so 10m3/ hr.m2 @50Pa was the target for building regs. I would say the average older house would be 20 or 30 on the test.

I got a 1 but full passive is a 0.6 so even without ventilation you still get air moment.
The energy saving from having a controlled envelope is massive though. My house will have a volume of 800m3 so a volume change every 2 hours is 800m3 of fresh air, as it is piped in from out side. Bathrooms are extract points as is kitchens utilities and delivery points are all over the home including bedrooms etc.
So smells are booted and fresh filters air is provided. All with heat recovery as required.

I think your health should have been the priority when designing your home.

It’s was, filtered air, room sealed wood burning stove which draws air from outside. Stable temps.
No hot or cold spots, no damp, no drafts. Only one bill for energy electric.
No burning heating from oil or gas which can creat inherent safety issues if they go faulty, if my GSHP goes wrong no carbon monoxide issues etc. same for the wood burner with its own air supply and the stove being room sealed after lighting the risks of fire and carbon monoxide are nearly zero.
Safety was top of the list. Fire corridor, connected smoke alarms so if one trips they all sound.
Escape windows in every bedroom over and above building regs requirements. Every door in the house a fire door.
With fire strip edging seals.
Same on ducting fire safety strips on any passing into the fire escape corridor etc.

And I designed it all myself because thats the way to know what’s done is done right and fitted the majority of the passive and ventilation stuff myself. And purchased and chose everything used in the build.
I know every aspect of my home.
I will say the latest change a robot mower was by far the best choice for keeping the grass cut, it’s never looked better and require so little effort and cost so little. This years grasss cutting so far of 3500m2 50kwh of electric so £15 of electric for a perfect lawn on 3500m2 of grass, it never looks like it needs cutting. Add on £10 for new blades it uses it costs a fraction of what it did when I used a ride on mower. And it cost half the cost of a new ride on mower.

I just love your posts everything you do and have is wonderful and the best and you throw in these facts like “it cost half the price of a new ride on mower” well it might do but that completely depends on what type of ride on mower you buy. I’ve compared the prices and I can get ride on mower’s for a lot less than the price of a robot mower. This is just typical of the half truths that you keep posting but your posts are amusing .

Indoor plants produce oxygen day and night. They can be used as a method of combat against daytime and nocturnal hypoxia as mentioned a moment ago by ollie989898. Nocturnal hypoxia causes various medical calamities that can be expensive and soul destroying. One of them is the early onset of dementia. I note the absence of any cash being spent on methods of combat against hypoxia as part of your priority.

Chinese investors have invested huge sums of money in the construction of a nuclear power station at Hinkley Point. When it starts to produce electricity there will be some very large bills dropped through the letterboxes of British consumers. Furthermore, trillions of tonnes of boiling wastewater will start to be dumped into the sea.
