Hello - the key point is on CO2, 9% of our electricity came from Biomass (including Drax) in the last 12 months, ~31% from wind and solar. Even if all electricity came from gas power stations, a heat pump would still be using less gas than a gas boiler. The grid has a mix of sources that provide electricity, in my region, most of the electricity comes from wind and nuclear power stations. Heat pumps are objectively lower CO2 than a gas boiler in my region, and the UK. Where did you get the cost for a heat pump? Average costs according to MCS are around £13k, considering the boiler upgrade scheme grant or £7.5k, this would be a cost of £5.5k to install. At the moment, gas bills are subsidised and electricity bills punished, so there is not a major saving to install heat pumps, even though for me in the last 12 months, costs have been around £200 lower than a gas boiler providing the same comfort. Ultimately, we need to decided whether we want to reduce emissions, as we move to more wind and solar, the grid will get cleaner, and therefore if we have electrified heating, with a heat pump, our heating emissions will keep going down. With a gas boiler, we are locking in emissions for good. I realise that spending several thousand pounds on a heat pump is not everyone's priority, which is why we need better grants, subsidy, cheap loans, or other incentive to help people switch. Thanks Tom

There are quite a few critiques of Michael Shellenburger online, why do you cherrypick arguments that support your perspective rather than listening to the majority of scientists?

Wouldn't that be convenient, a 3rd ice age, just in time to prevent catastrophic warming

Thanks Bob - this is terrible news. And locks in high cost and high emissions homes for years to come. Really odd that you would celebrate this. Notice you have not replied to my comment about your terribly biased documentary, doesn't stand up to scrutiny does it? Have you watched the documentary I shared, doubt it!

Not celebrating anything . I’m just glad I didn’t waste a massive amount of money on this over complicated nonsense. Not read your rebuttal I’m afraid but can imagine that you would find a video , survey or something to discredit it. The heat pump bubble has burst I’m afraid. But you’re going to have to make it work for years to come unless you move. But you might have trouble as people aren’t buying houses with heat pumps. 😢

Only 2 minutes in and it's a video repeating the same old misinformation. Just because someone whos anti-heatpumps says something doesn't make it anymore true.

It’s very disappointing and locks in high bills for new homes, as well as high emissions.

@ Housebuilders didn’t want it and neither did home buyers because of the higher costs associated with installation which would drive up the price of new homes Retrofitting also costs a fortune compared to gas installations No one is convinced that it’s cheaper in the long run to install a heat pump People don’t want to take the risk when there is a tried and tested method of heating homes which is cheaper and more practical It’s a fantastic result 😀👏

@@liveloud9894 I am not sure what house-builders want is necessarily good for society, the quality has been low for many years, whilst their profits have soared. Exactly, we should not be retrofitting heat pumps but installing at construction - not including a gas supply to a set of new homes can significantly reduce costs for construction. If installed with solar panels, as were the proposals, costs for heating and hot water can be close to zero - just look at the zero bills homes project by Octopus - octopus.energy/press/octopus-energy-and-sng-deliver-first-zero-bills-homes-for-social-housing-residents/#:~:text=Launched%20in%202022%2C%20%27Zero%20Bills,guaranteed%20for%205%2D10%20years. Gas prices have driven the energy crisis in recent years, reducing our reliance on gas can help minimise risk of huge prices in the future. Tom

@ Yes, I agree with you on the house builder issues , poor quality and sky high prices but unfortunately the large companies are in total control of large scale new builds If they can’t make the margins they need then they won’t build Everything is on their terms and it’s definitely not good for society Change is needed there but it will take a brave government to deal with the problem

Hi Richard, it sounds like an exciting project. A couple of thoughts - yes there will be a high temperature heat pump that could heat your home, although if you are able to, increasing the size and or number of radiators would mean that any heat pump would operate more efficiently. - any ways you can increase insulation would decrease costs but not necessarily required to install a heat pump - if couple with a battery and solar, running costs could be very low in comparison to an oil boiler, even if a modern one. - you are right in identifying the more consistent temperature a heat pump provides as a positive! I hope you would be able to install. Ultimately, if sized and installed well, a heat pump can heat any home. So, I would encourage you to get a few quotes and see what is possible! Tom

Well said! I’ve also been a heating engineer for over 25 years. About time this narrative is questioned.

How are you heating your hot water for 0 with a gas boiler in summer?

Hi Richard - great that you install heating systems, £3 per day obviously would vary depending on the size of house, weather, internal temperature etc. A gas boiler keeping my house comfortable was not £3 per day. Heat pumps have a £7500 grant to help support the installation. Many will cost the customer similar to a gas boiler. I would encourage you to look again at heat pumps, we need your skills and experience if we are going to reduce reliance on gas. And your last point about climate - absolutely it has been changing, but since humans have existed, it is unlikely to have changed this rapidly. There is risk of catastrophe, surely we should do whatever we can to minimise that risk? (As well as reduce pollutants like NOx which damages are health, reduce reliance on dodgy regimes around the world, and reduce risk of gas price volatility) Thanks Tom

@@BenIsInSweden Dishwasher for washing up , electric shower for shower and sink, air fryer to cook, kettle for tea and coffee.. Total electric per day about 80pence (UK)

@@richardlewis5316 so not a benefit of a gas boiler then. Heat pump would cut the cost of the hot water used for shower and sink by about 1/3rd. And the cost you talk of for a heat pump "£15,000" isn't for the heat pump. most of that is for switching to low temperature heating, which would benefit gas boilers as well. £3 per day is about 47kWh at current price cap. Multiplied by 90 is about 4230kWh, typical annual gas consumption of a UK home is over double that. Unless things have changed in the UK and winter now lasts 6 months 🤷

Thanks Bob, I was at work all day Friday and away this weekend so not had a chance to watch your documentary. I will watch and thoroughly debunk it when I get a chance. I don’t want a few heat pumps, I want 25 million to replace gas boilers in the UK Thanks again for commenting, more comments on my videos means that TH-cam will push the videos to more people!

Hi Bob, watched the documentary, and have a few thoughts in response. Firstly, the documentary is targeted at the low carbon economy but then goes on to discuss the problems of mining, our existing extractivist economy and the use of material broadly. I would respond with this graph - www.energy-transitions.org/bitesize/its-in-the-charts-materials-needed-to-deliver-the-energy-transition/#:~:text=Between%202022%E2%80%932050%2C%20the%20energy,of%20steel%2C%20copper%20and%20aluminium. - i.e. the amount of coal we currently mine each year is more material than we would need in the total energy transition. So if you have some problems with the impact of mining, you would want to transition away from the existing economy. Once we have transitioned to a low carbon future, our impact on the environment will reduce substantially. And the environmental disaster of the fossil fuel industry will no longer be required. 2nd, as a chartered environmentalist, I work to reduce environmental impact at my workplace and in my community, I am thoroughly aware of the impact of mining in the UK, and around the world. As the documentary ends, we need to move away from the growth focussed economy - more more more, towards a circular economy, possibly built on principles around 'doughnut economics' popularised by Economist Kate Raworth. This is exactly what we need to do, moving away from fossil fuels would make this much easier as we would need to mine significantly less material than our current system. One thing to note, is that from a primary energy point of view (one metric we could use to understand how much material we use) moving away from thermal energy plants (i.e. gas power stations), from internal combustion engines and from gas boilers, towards renewable energy generation, electric vehicles and heat pumps would use significantly less energy as low carbon technology does not have the losses that thermal energy plants do. I would encourage you to watch the documentary 'Big Oil Vs the World' - it is in 3 parts so asking a bit more of you than you did of me... 1st part here th-cam.com/video/I32R6Yx9PTI/w-d-xo.html You may not 'believe' in climate change, but if you care about mining and environmental impact, then moving away from our business as usual is key to minimising that impact. All the best Tom

Thanks for your encouraging comment! And well done on all your progress, and agree, lobbying locally, regionally, nationally can have a great impact. Whether in communities, workplaces / organisations or with government. What do you think is the best approach to that? Thanks again, and happy new year!

Thanks John - kind of you to comment

Hi Jezza, a few points to make.... Depending on how you count, we have only installed roughly 250,000 heat pumps in the UK, this is 1% of the number of domestic gas boilers around the country. Heat pump users are still early adopters, but in the 3 years I have had mine, I have learnt a lot and I think the conversation on heat pumps has changed considerably. These lessons learnt will be common amongst those who have installed already or will install Because I work in this world, I am more interested in the tinkering, although it was not required, I know of several heat pump users who do not tinker in the same way. Yes we are using more heat, and we are more comfortable than when we had a gas boiler. Over the three years of having the heat pump, I have decided to live with the heat pump on 24-7, and target comfort + efficiency, this means we have used 6% more electricity, but delivered 11% more heat in 2024 vs 2023. I am happy with this. The figure for heat delivered by a 95% efficient gas boiler would be 12,000 / 0.95 = 12631 kWh of heat, if our boiler was 85% efficient this would be 14,118 kWh of heat. My assumption that it was 95% is not based on any data but to be conservative in my estimates. I don't think we should pay too much attention to that, and the key numbers are that 12,000 kWh of gas has become 4200 kWh of electricity, and we are more comfortable. All this is only complicated because I have shared the detail. It is really quite simple to run, heating is ON, from the middle of autumn to the end of spring. The house is constantly warm. I have a feeling that this won't answer your comments, sorry, but I hope you can see where I am coming from? Thanks again for engaging Tom

@TomBray-LowCarbonLifestyle Thanks Tom, for engaging also👍 I know I'll be accused of being a troll, but I don't care! I like to question everything🙃 I've got a 14 year old 37kw Combi boiler, so I know that in a year or 2 it Will need replacing, like most people out there, I'm aware we need to change from burning stuff, but I'm not a passionate advocate like yourself. So I will do massive amounts of research and see if heat pumps that we have now, are a viable option! I will relate it to EV's, if I owned an MG diesel car and for environmental reasons I wanted to get an Electric MG, when I popped down the car dealership, they said to me, sorry Mr Jezza, the electric vehicles we do now are the size of a Long wheel base transit van, we need it that large to get all the flux capacitors in and the associated pipe work, also you will have to enlarge your drive! A bit tongue in cheek, I know, but that is what it's like, going from a white box boiler on the wall that I have now, I can control the temp of the hot water, I don't need a wasteful tank of hot water, that I might or not use, I don't need legionella cycles, I can have different temp TRV's in rooms and not heat others, I don't need to run it for 24 hours, coz I dont need it when I'm asleep! We are home all day and our heating is on from 07. 30 to 21.15hrs at 20- up to 21.5 degrees when we sit and watch the TV, our gas usage is estimated this year to be 9780kwh for a largest 4 bedroomed 1929 built extended semi. I'm not a disbeliever in the heat pump technology, it's proven, I just but don't believe the costs that are banded about in using them. If you have lots of Solar and big batteries, you can offset the costs, as someone said, "I can't produce enough gas, but can make my own electric". I actually think All this backwards working out, is nonsense! what it would of cost with a gas boiler at 90% etc. No disrespect but Even some of your figs just don't stack up. There is no way that your house should ever need 14,791 kWh of heat, I suggest that would of been way over your original heat loss calculations. The nation as a whole has cut it's energy consumption by 6%, you have managed to up your electric consumption by 6.65%😀 Sorry, I'm rambling🙄 I think in a few years time people will be laughing at these heat pumps, "What were they thinking"! Anyway, keep at Tom, you never no in a couple of years you might be using even more electric😀 I'm off to have my medication😛 Take care👍

Thanks Ken, some helpful points there. Yes I think that it was installed too close on the right hand side, the service engineer did not mention this, but I had picked this up previously, and fairly disappointed that our installer did this. It does not seem to be causing too much of a problem Thanks for the helpful context more broadly. All the best Tom

Hi Stephen - very true, although HSE guidance is to store above 60° not 65°. Most heat pump systems have a pasteurisation setting that will lift water above 60 once a week to minimise legionella risk. Tom

It is 65c and has to be that temperature constantly. This is the major flaw with heat pumps. You have to run an electric heater to boost. Otherwise legionella can occur in between .

@@Cyberbobxxxx www.hse.gov.uk/legionnaires/hot-and-cold.htm What do you mean by electric boost? All heat pumps are electric! The system does not use an immersion coil to heat above 60

⁠if read it it’s has to reach the tap at the correct temp. That’s why it’s at least 65c . How hot is your water out of the tap? How hot is your pump heating the cylinder? Not 65c . It will have a 3kw heater in the cylinder.

@@Cyberbobxxxx no it doesn't.. His heat pump can do 75C without an immersion.

I live in a similar property 3 bed detached I run my Combi at 50-55 degrees for most cold days (2 degrees) which costs (according to my smart meter) about £2.60 per day so for Nov - April it costs £312 in fuel cost. For days when I'm out its off. Adjust the flow temp to suit the outside temp and the boiler works in full condensing mode

@ . Yep similar for me, gas bill is about £640 per year.

Hi both - I guess a point to remember is my home was built in the 1880s, so could be a bit leakier than a 2001 build! Richard, altering your flow temperature is great. The heat pump users weather compensation controls to do this automatically. Thanks Tom

@@TomBray-LowCarbonLifestyle Weather compensation systems are all very well but my trusty gas boiler can be turned up to 70 to heat a cold house very quickly. Then I turn it back to 50 when house warmed in about an hour!! Old fashioned I suppose but very efficient! Cheers

@ . Have you insulated under your ground floor?

Varies depending on external temperature. But if moved from a gas boiler it would be between 1/4 and 1/3rd of the kWh a gas boiler would use.

Hi Robin, yes I think that could be true, although it would depend on expected mileage and current heat loss of your home. A simple rule of thumb would be every kWh of gas you use has similar emissions to every mile you drive in an average fossil fuel vehicle ~200g each. So if you drive 20,000 miles a year, that would be a bigger priority for switching to an EV than a home that used 8000 kWh of gas. We are looking at a second hand EV at the moment, that is much more reasonable price than a new car. Tom

Rather than the heat pump being expensive to run, your house is expensive to heat. You'll need to internally insulate the walls with a breathable insulation like wood fibre or cork for example if you want to reduce the heat loss.

@ is my EWI not acceptable?

Hello! I mention it in this video - we have a dedicated heat meter measuring heat output. This is a Sontex Superstatic 449 heat meter. Thanks Tom

@@TomBray-LowCarbonLifestyle That doeswn't explain how the heat is measured, just what measures it. What exactly is it mearuring, and please don't say temperature.

​​@@iareid8255they often have an ultrasonic monitor for flow measurement through the pipes. So for a given pipe size, the ultrasound can measure how fast the volume is moving and therefore how much heat is travelling in it. Compare it vs the return temp and that's the heat delivered.

@@iareid8255 A heat meter measure the flow rate of the water leaving the heat pump, and the temperature difference between the flow and return pipes. The heat capacity of water is known, so it can do some simple maths to calculate the heat output. There's a lot more detail on line, but most home owners don't need to know the details, just like they don't need to understand all the complexity going on in an electricity meter.

@@iareid8255 Google is a great resource for getting answers like this, maybe you've heard of it?

Hi Jezza - I guess this is the wonder of a heat pump and its efficiency. Although we delivered more heat, we used less energy. Ie ~12,000kWh gas to ~4200kWh of electricity. The total energy we delivered may have increased but ~10,000 kWh of this energy was for ‘free’ from the air. This means we have decreased our energy consumption by 2/3rds, the extra we have used is recycled heat locally as it leaks from our home. If our target is reducing energy consumption then heat pumps would be a major step. I hope this makes sense? Tom

@@TomBray-LowCarbonLifestyle thanks for the reply👍I get that the heat pump produces more energy than it consumes. Im with you on the technology and saving Co2 etc, but surely, with figs you've produced, your energy consumption has gone up by over 30% on the 2020 figs? Since Youve had the heat pump your heating and hot water energy consumption has gone from 12,000kwh using gas to 14,790kwh with the heat pump? You have then said you would of used 15780kwh of gas! Sorry Tom, am I missing something? It doesn't add up. If in 2020 you needed 12,000 kWh, but, why do you now need 15780kw?

​​⁠I guess the change to note is that we are now much more comfortable. We are using more heat, keeping the house at a more comfortable temperature. And the comfort came as a consequence of me trying to improve efficiency. Ie running for longer hours at lower radiator temperatures. So we now deliver more heat than we did in our first year with the system, but use a similar amount of electricity. I take your point that the house has used more heat this year. But the key point is that it has used less energy Thanks for getting into the detail! Tom

​@@jezzaandrews1940 you're right. As Tom was saying in the video he didn't want to heat his home fully with gas, as he was feeling guilty about it causing emissions. He eluded to disagreements about what temp to keep the house at etc in the family. So because he's now happy using a lower polluting method of heating, he's happy to keep the house warmer. At least that's my interpretation of the situation. I do the same. I under heat my house because I don't want to be using "Putin juice" or "Saudi juice" But with a heat pump I wouldn't care.and probably use more delivered heat energy.

I ran my gas boiler at 30 ish flow temperature 24/7 and it cost me about £4 a day ish and my house was really warm. My heat pump running 24/7 on octopus intelligent cost me about £3 a day.

@@mackay250 I think that is the key, low flow temperature. I was a victim and also guilty of using my boiler at very high temp hence only operated it 10hr/day. I learnt a lot when researching on heat pump that we can potentially save money and have cosy home with boilers, only factor left to tackle would be co2.

Yeah a low flow temperature saves money and uses less co2. Makes your house very warm all day too. I found when it was -2 outside I needed 35c flow. Everyday I would adjust it to the weather forecast. Worked very well. Everyone should do it.

@@mackay250 Do new boilers come with weather compensation system like heat pumps have so that you don't have to adjust flow temp daily? Just asking for anyone reading is thinking of installing a new boiler instead of heat pump.

@ Yes they do, but most don't as with mine so I just did it every morning.

That video is just propaganda for the fossil fuel industry, I suggest people either don't bother watching it, or watch it very critically. Hint, they say a lot of things that either aren't true, or heavily exaggerated, while ignoring the huge problems of using fossil fuels.

All of 60p a day. The electricity cap has gone on the 1st so cancelled out any savings.

@ In the Netherlands it saves more. But don't underestimate how much a heat pump can stretch 60p worth of electricity.

You have to use the 3Kw ELECTRIC HEATER every week to kill the bugs as the heat pump won’t go that hot. Needs 65c for a couple of hours a week. Remember to factor that into your savings!!

@@Cyberbobxxxx the valiant ashp can reach 70c so it does a legionella cycle without difficulty and no back up, so doesn’t need an immersion heater to do this.

My heatpump runs a legionella cycle weekly. The heat pump factors that in. I have R32 refrigerant which does reach around 58 degrees before the immersion cuts in. Legionella only needs 60 degrees for 3 minutes. The immersion is only heating the last 2 degrees which is costing around 15p a week.

​@Cyberbobxxxx No it doesn't. As long as the water is not stagnant (I.e. tank being replenished regularly) then it doesn't matter what temperature the water is at.

@@Cyberbobxxxx No, you don't 😂 My hot water cylinder has a 1.8kW immersion heater, not a 3kW one, and that's sufficient to top up temperatures above 55C if needed. I usually set my cylinder to 52C, which is above the Swedish regulation minimum of 50C for heat pump systems. While 52C takes longer to kill Legionella compared to higher temperatures, I could use an anti-legionella cycle (ALC) to heat it to 60°C+ with the immersion if needed. A 3kW heater is unnecessary for this!

And the environmental disaster of the fossil fuel industry will no longer be required. 2nd, as a chartered environmentalist, I work to reduce environmental impact at my workplace and in my community, I am thoroughly aware of the impact of mining in the UK, and around the world. As the documentary ends, we need to move away from the growth focussed economy - more more more, towards a circular economy, possibly built on principles around 'doughnut economics' popularised by Economist Kate Raworth. This is exactly what we need to do, moving away from fossil fuels would make this much easier as we would need to mine significantly less material than our current system. One thing to note, is that from a primary energy point of view (one metric we could use to understand how much material we use) moving away from thermal energy plants (i.e. gas power stations), from internal combustion engines and from gas boilers, towards renewable energy generation, electric vehicles and heat pumps would use significantly less energy as low carbon technology does not have the losses that thermal energy plants do. I would encourage you to watch the documentary 'Big Oil Vs the World' - it is in 3 parts so asking a bit more of you than you did of me... 1st part here th-cam.com/video/I32R6Yx9PTI/w-d-xo.html You may not 'believe' in climate change, but if you care about mining and environmental impact, then moving away from our business as usual is key to minimising that impact. All the best Tom

Hi Bob, thanks again for commenting on my videos, more comments means that TH-cam is more likely to recommend videos to others, I need all the help I can get, so thank you! You make a fair point about the resource use and treatment of workers, particularly in the manufacturing of solar panels, something I talked about in videos in the past. We absolutely should be campaigning for worker's rights all around the world, in the solar panel industry, and in the oil and gas industry, we should also be clear that there is a much longer history of human rights abuse in that world. The impact on fossil fuel mining for coal, oil and gas has caused environmental damage all around the world, polluting water courses, increasing cancer rates, damaging habitat. On a much bigger scale that renewable energy ever will do. It is brilliant that you care about this too. Others have calculated life cycle emissions of low carbon technology and you can read about that in peer reviewed articles here - www.sciencedirect.com/science/article/pii/S2212827122000580 (heat pump carbon intensity 70% lower than gas boiler) I have talked about how solar panels are no longer an investment for the environment as they are displacing already low carbon electricity, but they help lower costs of electricity. I talked about some of this in this video - th-cam.com/video/F3KQjgTMGIg/w-d-xo.htmlsi=MSma9Rv9aEthM3VS Also, I have talked about my doubt around batteries here - th-cam.com/video/Fh9j-kGDGto/w-d-xo.htmlsi=3SiOLe4ATdYXNpVl It is flattering that you spend so much time commenting (21 times!) on my videos, but a little bit odd I must admit. I admit that I do not know everything about low carbon technology, but as a chartered engineer and chartered environmentalist, with 12 year's experience working in engineering consultancy and public sector teams, I do have some qualification to talk on these issues. Thanks again for engaging Tom

Good stuff

I thought that could be the tricky one for some! Less is better than nothing!

Natural after all that mining, processing and transportation, yep. That is like saying a coca-cola is natural because it has ingredients. Although using an old car may seem like a sustainable thing to do, it is just locking in emissions. If we were taking climate change seriously, we need to stop using fossil fuels as quickly as possible. Tom

By extracting and re releasing the locked in materials you are taking our atmosphere back to pre Carboniferous conditions , do you think thats good for todays eco system?

Thanks for sharing your context in Lithuania, solar panels are definitely great to supplement heat pumps. It is great you have had very low bills since 2022!

Hi Stephen, that is a good question about running the boiler at low flow temperatures and on weather compensation like a heat pump would have, this would also improve efficiency of the boiler. I have seen a video on TH-cam that has looked into this further - th-cam.com/video/fnrOXNG-32U/w-d-xo.html Unfortunately many of our boiler installations will be done as cheaply as possible and without controls for efficiency. I would say our house is pretty average, a small extension on the ground floor is well insulated, but front of the house is solid brick and unfilled cavity, and although we are a terrace, we are also on a hill, so there is a significant part of our side wall that is exposed to the elements. We have 300mm loft insulation, but a ventilated floor. So I think... we are a fairly average UK home. We measure heat using a dedicated heat meter connected to the pipework running from the heat pump. This is a Sontax 449 - www.dmsltd.com/p_78_sontex-superstatic-449-heat-meter and was installed as part of our installation in 2021. Thanks Tom

Hi live loud - that isn't quite true, a heat pump uses electricity from the grid that has generation from a mix of sources. Only 35% of grid electricity was from gas in 2024, so the rest from low(er) emissions sources. But even if a heat pump got 100% of its electricity from gas, it would still be using less gas than a gas boiler. In terms of embedded emissions in the manufacturing process, myth 12 in this article talks about that for heat pumps - www.carbonbrief.org/factcheck-18-misleading-myths-about-heat-pumps/, this tool helps work it out for cars - www.iea.org/data-and-statistics/data-tools/ev-life-cycle-assessment-calculator - in the UK a new EV will pay for itself in less than 2 years of average driving. You are going to be gutted to hear that gas boilers and fossil vehicles also don't grow on trees, and take an awful lot of energy to manufacture and transport, as well as the energy used to mine, process, and transport oil and gas to power them. Are you offering me a free electric car?! That is very generous and of course would review it. I am planning to buy a 2nd hand EV, with some savings that my wife and I have worked hard to earn. I am sure I will make a video about it. Thanks for engaging so helpfully! Tom

@ How much Chinese steel is imported to the UK each year and what fuel is used to produce it Hey why don’t you get one of those BYD cars , I’ve heard they’re cheap and that would demonstrate your commitment to tackling the elusive climate change and stopping the sea levels from rising ( which hasn’t happened yet but will do soon ) Also as a way of reducing your carbon footprint are you going to remove all plastic / nylon/ pvc products from your home and see how you manage Your laptop and internet use needs to stop too , have you seen how heavily reliant on fossil fuels this industry is , have you seen their carbon usage , up 48% last year according to reports Have a look at Google’s reliance on fossil fuels, 100% according to reports Did you realise 82% of the global energy production is from fossil fuels Oh dear 🙁

@ The “ facts “ you refer to in the links above are from two organisations set up to push the net zero agenda so it’s hardly surprising that they will present data in favour of promoting EV and heat pump sales Show us something independent and not funded by Rockefeller / Bloomberg and various governments around the world

@@liveloud9894 Hello - you seem quite upset about all this, and suggesting that any progress on emissions is not worthwhile the effort unless we are perfect. I wholeheartedly admit I am not perfect, even my dog would tell you that, but doing my best to reduce emissions and help other people understand the impact they could have. Yes we live in an imperfect world with emissions in every part of our economy, that does not mean we cannot make it better. The key points about reducing carbon footprint are the fossil fuels we burn, i.e. fuel in cars and gas in homes, the carbon footprint of much of the other things we use will be pretty low. Including internet use and plastics we use in our day to day. This is a helpful page on the impacts of climate change - ourworldindata.org/temperature-anomaly what are your thoughts on that data? Similarly a graph of sea level change - ourworldindata.org/grapher/sea-level - there is a lot of evidence that humans have impacted on climate. And that we need to do something to minimise that impact. There are a lot of reasons not to want to change, but that would increase risk of catastrophic change around the world. Tom

@ No, not upset just irritated with people’s delusions There are many of us old enough to notice how different generations are taken in by this trumped up climate change lie In 30 years time when the climate is still the same and the sea levels still haven’t risen a millimetre and the polar ice caps are still as big as ever then you too will realise you have been conned But the lie will continue because there’s money to be made Where there’s money there’s deception
