Net Zero - its over.

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 on

I don't think he is responsible for that any more than you would be for lithium mined by children in Africa.

Fwiw ULEZ is not just about health. Old cars were naturally disappearing over time anyway

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.

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.

If the 50% of air inside of the house is pressurised by the outside pressure then what happens to the other 50% every hour?

Trying the guilt complex with health and calling it "Low" ?

Truth is that if particulates were a problem then people should not be subjecting their children to living in such an environment. Instead they'll sit there in the midst of Pollution whilst Khan takes his £12.50

IMHO this speaks volumes about the whole situation - it's Politics.

Stuff your fake concern about others & pretend hurt about my "Agenda" - if people like you were so concerned you'd already got vulnerable people to move to better climates decades ago.

Everyone won't be able to do what you have done and it blatantly obvious you are a Zealot.

There are a few million industrial and domestic gas appliances being used day and night in London that emit medically harmful Nitrogen Dioxide. I note that the users are not being charged £12.50 by Mr Khan.

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.

Looking at Gridwatch a few moments ago shows 50% of production is by natural gas which costs typically 200-400 per MWh as against my figures above. We wont see any reduction until renewable takes 70-80% of the load. Apparently only 5% of suitable domestic roofs have panels installed but that still amount to 5GW, so there is plenty of room for expansion there. Since renewables are essentially modular in design installation can continue until we have significant excess production at peak times. See post 287.

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.

Yes, pursuing the nuclear route is a blind alley compared to rolling out more renewable. I've seen people proposing the building of nuclear to offset the intermittency of renewables but reactors are not suitable for intermittent loads. Gas generation is ideally suited for peaking and stability so we need to keep the gas stations but move from natural gas to hydrogen and biogas generation. Hydrogen should be produced by electrolysis using the renewable excess output and stored ready for use at the same site so no transmission difficulties to worry about, electricity in and electricity out.

Methane is four atoms of hydrogen. Nuclear power stations use lots of hydrogen.

I think I can see why electricity in the UK is so expensive- companies are gouging customers.

Natural gas has fallen to previous levels(ish). Although to be fair, the HM gov't did make the larger companies take on the customers let down by other suppliers going pop so perhaps there is a reckoning to be had but even so, prices above 15p a unit are a bit sore. You can generate all the power you want for £150/MWh, surely.

anybody else read that the concrete bases for onshore wind turbines will need to be replaced every 25 years ?

Newer designs of nuclear can be run up and down more readily but since their fuel cost is near irrelevant there would be no reason to do so. You run them flat out, you gain nothing by ramping output down.

Nuclear is the only answer in reality if you want to seriously address the amount of fossil fuels being consumed in the UK.

Not surprised.

 

[ollie989898]

Methane is four atoms of hydrogen. Nuclear power stations use lots of hydrogen.

Most thermal powerstations use hydrogen to cool the generators. Nuclear power does not consume hydrogen in any other way. Conversely, they actually generate the stuff as a by-product. Not controlling how it collects and sorting it is how Fukushima happened.

 

[DaveGrohl]

Nah, windpower is forever.

Ish.

I speak as someone who has a turbine. Our turbine has to be demolished after 25 years cos that’s the planning conditions., whether it’s still generating leccy or not. Bureaucracy trumps reason. That’s actually the world that we live in.

And yet photosynthetic absorption of CO2 by all of the plants on my farm don’t count as carbon absorption……

Meanwhile, schools aren’t going back because they made concrete with bubbles. They’re not collapsing, they’ve just got bubbles. But we’re now proposing concrete with bubbles for climate change purposes…..

Nuclear is the only answer in reality if you want to seriously address the amount of fossil fuels being consumed in the UK.

If nuclear is to be the answer to the intermittent nature of renewable then running them flat out means they are base load and will not have any effect on peaking so you still need peaking generation for which gas turbines are the optimum answer.
Nuclear will be obsolete in the next 20 years because it just cannot compete with the cost structure of modular renewable. Mind, we will still be paying for it as Dave says in post 439. We'll just have to hope we will only be paying for one and not the gov plans for 24GW.

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 .

It was half the price of the ride on mower we own, it’s on its last legs. A Westfield T1600 I would not want anything smaller or less well made. We cut a very big area with it including the farm yard. Just short of £7k for the same model as ours but new, £3.5 k for the robot £200 to set it up. One designed for the area we cut smaller / cheaper are available. Flymo is the same, as husqvarna. While flymo is there more domestic targeted range.
The ride on now cuts about 2% of what it did so while it only had a few seasons left in it, now it has a lot more.
It can limp on doing the little bits left for a long time now.

The robots running costs are a fraction of any ride on mower even if your time is given free. If you include any value to your time then the robot mowers are the best time/ money saver for those with big lawns can get.

next door gets a garden service it’s £60 per visit the area they keep tidy is 20% of that the robot does.

I value my time I now spend only 40 mins per month 2-4 tidy ups of the edges, on our lawns rather than the 6-12 hours it used to take to cut them to look like someone owned them.

the robot is an extra member of staff, he cuts when I am harvesting, he cuts when it’s raining, he cuts at night if I want.
He cut as often as I want him to, and he does a great job. He even gets to hard to reach places under trees we used to have to use a strimmer on.
I would never go back to a ride on mower, even if I had one given.

 

[Dave645]

Erm. How tight are you?

Very lol.
But not afraid to spend on the right things, but hate waste.
Always look to value for money even when that’s not often the cheapest option.
I am from Yorkshire. . . But from experience have learned, the buy cheap and buy twice, adage is true.
my dad had a fit when I got the robot mower, but actually said it’s the best thing we have ever bought. about 2 months in.
since we got ours they launched an RTK version that would have let me cut 90% or more of the whole yard with it. While an extra £1000 I think, it likely was worth it. It saves it cutting time as it can cut stripes if you so wish. As it cuts less randomly.
you don’t need to put a wire down at the perimeter, and it can be set up to exclude areas from the app. As and when needed, so spring flowers in grass can be left until they finish then remove the exclusion zone when done.

the next step to net zero gas cutting is here. . . Time to dump the petrol mower.
I for one don’t miss the fumes while riding around and round on my ride on mower.

Your posts really do amuse me. You really don’t have to justify everything you do to the nth degree. Just you wait until the price of electricity skyrockets you’ll be glad you kept your ride on mower!!

 

[Dave645]

I don't think he is responsible for that any more than you would be for lithium mined by children in Africa.

Fwiw ULEZ is not just about health. Old cars were naturally disappearing over time anyway

Get your facts straight it’s cobalt mined in Africa, and now that’s not used in the next generation of EV’s they don’t mine lithium it’s settling ponds for the most part. . .
Child labour cobalt is in your tablets phones and other small electric devices cars not so much anymore.

fud is great fud this old is so like a blast from the past.
Time to do some reading and keep up with the latest trends in fud. If you want to put EV’s down.

you think ULEZ will not have an effect?
You think air quality will not improve?

a 2016 car is not new by any means but they are exempt from the ULEZ charges.
With the £2k payment to help people to swop to a newer car who live in the zone, I think they are trying to be fair, I assume they are using the money from charges to help people buy newer cars by giving them £2k.

the ULEZ and EV’s are not the rules, if they were that would be unfair, 2016 cars or newer or cars under the emission rules yes old cars would have gone eventually but this just speeds it up.
Do I think the ULEZ zones are fair or needed, I don’t live in a city so air pollution doesn’t effect me, so I leave it to those that are effected by the air pollution to decide.

 

[Dave645]

Your posts really do amuse me. You really don’t have to justify everything you do to the nth degree. Just you wait until the price of electricity skyrockets you’ll be glad you kept your ride on mower!!

Lol I would just charge it from solar. The amount of energy it needs could be provided by a diy solar setup. Even if you don’t have home solar.

You would not get me to spend any more time than I already do on a ride on mowers, grass cutting is pointless work, unless it’s to make fodder.
I like a nice looking lawn, but have zero interest in the time it takes to get one using a ride on mower.

P.s they will ban from sale new petrol mowers very soon.
Engine emissions from small engine items like mowers are far far worse than any car.
And electric alternatives have been around a long time. Most tool makers now have mowers and strimmers, chain saws etc.
The missing link was bigger lawns, now that’s been filled with robots.

Lol, the reality is fossil fuels kill million each year, your advocating we stay with them because the alternatives are more expensive is just plain wrong when you add in the value of human lives, that fact you don’t seem to add that value makes you very selfish.

you don’t need to be a zealot to value human lives.
The fact your drum for fossil fuels is so blind to many facts makes more the religious zealot, blinded by everything that threatens your god fossil fuels so that name fits you better than me, I am a realist change is happening and needs to happen for many reasons.

Ps. Grouping me a zealot is a classic way to try to under mine a persons point of few by devaluing them by grouping them with seeming negative groups.

the fact I am just a normal family man, who happens to care that millions die each year from our continued use of fossil fuels, is not strange I expect it would be the majority’s opinion On the matter.
so painting me the zealot seems to talk more of you than me.
