The Sustainable Hour no. 610 | Transcript | Podcast notes
This week, The Sustainable Hour moves between a climate idea that needs testing and changes people can make now.
One guest imagines wind turbines spraying fine mist across dry landscapes. Another helps Geelong households make their homes more comfortable, cheaper to run and less dependent on gas.
• Mik Aidt opens with reports of destructive floods and a warning about the heat associated with the developing El Niño. He also marks a renewable energy milestone: for a brief period, renewables supplied more than 80 per cent of electricity on Australia’s main grid. From 1 October, Victorian households can sign up for the Midday Power Saver, which offers three hours of no-cost electricity between 11am and 2pm. Whether it saves money depends on when a household uses power and what it pays at other times.

In a Facebook-clip from The Electric Viking celebrates a momentary record on the National Electricity Market where Open Electricity recorded a peak of about 80.5 per cent renewables in the Australian electricity grid on 19 September 2026.
• In his global outlook, Colin Mockett OAM looks at the contest to succeed UN Secretary-General António Guterres. Guterres has spoken plainly about fossil fuels and climate danger. Will his successor show the same resolve?
• In a Youtube-clip from the ABC, Andrew Forrest calls for a cap on the fuel tax credits claimed by Australia’s largest diesel users. His argument is direct: why give big companies a financial reason to keep burning diesel when they could electrify their operations?
. . .
• In an interview Mik recorded in Denmark, refrigeration engineer Jesper Pedersen explains his proposal to mount water-mist equipment on wind turbines. He hopes the mist could cool hot, dry air and help form low clouds that reflect sunlight. He also discusses the considerable questions still to be answered – where the water would come from, what it would cost and how changing moisture in the air might affect weather. The proposal remains an idea for research and field trials, not an established way to cool the planet. Colin adds a Geelong connection to the conversation: refrigeration pioneer James Harrison.

• Back in Geelong, Lucy Allinson introduces Geelong Sustainability’s 2026–27 Electric Homes Program. More than 750 households have already taken part. This year, residents can explore home energy audits, insulation, draught proofing, heat-pump hot water, efficient heating and cooling, induction cooking, solar and batteries. The programme offers a choice of vetted suppliers, so households can compare quotes and begin with the upgrade that makes sense for them.
Lucy’s advice is to think ahead, particularly before an old appliance fails and a replacement becomes urgent. She also acknowledges the harder position renters face when improvements require a landlord’s approval.
The free Geelong launch event is on Thursday 8 October, from 6:15pm to 8pm, at Deakin University’s Waterfront Campus.

The Hour closes with our song Starting From Today and Lucy’s parting words: “Be wise. Think ahead.”
“I really recommend just take one step on this journey. You don’t need to conquer it all in one go, but just have a look at either your hot water system or just your insulation and we’ll help you on the way to find the best way to do it.”

We at The Sustainable Hour would like to acknowledge the traditional custodians of the land on which we are broadcasting, the Wadawurrung People. We pay our respects to their elders – past, present, and emerging, and extend that respect to all First Nations people.
The traditional custodians lived in harmony with the land for millennia, nurturing it and thriving in often harsh conditions. Their connection to the land was deeply spiritual and sustainable. This land was invaded and stolen from them. It was never ceded. Today, it is increasingly clear that if we are to survive the climate emergency we face, we must learn from their land management practices and cultural wisdom.
True climate justice cannot be achieved until Australia’s First Nations people receive the justice they deserve. When we speak about the future, we must include respect for those yet to be born, the generations to come. As the old saying reminds us: “We do not inherit the Earth from our ancestors; we borrow it from our children.” It is deeply unfair that decisions to ignore the climate emergency are being made by those who won’t live to face the worst impacts, leaving future generations to bear the burden of their inaction.
“The Indigenous worldview has been marginalised for generations because it was seen as antiquated and unscientific and its ethics of respect for Mother Earth were in conflict with the industrial worldview. But now, in this time of climate change and massive loss of biodiversity, we understand that the Indigenous worldview is neither unscientific nor antiquated, but is, in fact, a source of wisdom that we urgently need.”

Have you asked: who is benefitting from all of this?
EDITORIAL by Mik Aidt
A powerful El Niño is building in the Pacific. Scientists are warning of a dangerous summer. And the Coalition’s response? They now promise us a bill tearing up Australia’s climate laws.
The party says it would scrap the net zero law, remove rules requiring big polluters to cut emissions, ditch standards for more efficient cars and cancel most proposed offshore wind zones.
One Nation is already campaigning to scrap net zero and back coal and gas.
They call fossil fuels “cheaper power”. But where is the evidence?
Australia’s national science agency CSIRO – the Commonwealth Scientific and Industrial Research Organisation – says the cheapest way to build the electricity system Australia needs is with renewables backed by storage. An ageing coal plant does not become cheap or reliable because a politician says so.
And Labor cannot claim the moral high ground. Albanese talks about climate security overseas while his government keeps approving new and expanded fossil fuel projects at home.
This goes beyond electricity. We have an economy built on digging up, burning and throwing away more each year. We need to use fewer resources, repair more, and stop approving new fossil fuel projects.
People need affordable power. They also need a liveable country. Politicians who tell us to choose between the two should be asked one blunt question:
Who benefits when we keep putting this off?

The electric home
Electric Homes Program returns to help households improve comfort and cut
energy bills ahead of scorching summer
More than 750 local households have already trusted Geelong Sustainability’s award-winning
Electric Homes Program to make their homes more efficient and affordable – and now it is back for
2026–2027.
The Program removes the guesswork and barriers many people face when trying to improve home
comfort and efficiency by connecting households with trusted local suppliers. Participating
households from its first three years are estimated to be saving $445,940 on energy bills each year,
with projected savings of more than $11.6 million over 25 years.
“Electrifying our homes is a vital part of the transition to net zero,” says Karina Donkers, Co-CEO of
Geelong Sustainability. “With a very hot summer approaching, now is the perfect time to make the
switch from gas to electric appliances, to feel the benefits of improved comfort and lower energy
bills as cooling demand increases. We’re making it easier for households to find trusted providers
and solutions that work for their home and budget.”
Through the program, households can explore a range of solutions to improve the efficiency,
comfort and affordability of their homes, including:
● Home energy audits
● Draught proofing
● Insulation
● Heating and cooling split systems
● Hot water heat pumps
● Solar and battery systems
● Induction cooktop installations
● Electric vehicle chargers
● Water efficiency
Now entering its fourth year, the program is launching at 6:30pm on Thursday 8 October at Deakin
Waterfront, introducing an enhanced model that gives households more choice, flexibility and
access to trusted providers across a range of home energy upgrades.
Geelong Sustainability has carefully selected participating providers for quality, customer service,
warranties, value and experience, helping households explore their options with confidence.
Electric Homes participant Gail Nielsen says of the program, “Electric Homes helped me find the
right people. The company did a terrific job and were such lovely people. Very reliable and I was so
impressed with their care and turning up when they said they would that I used them twice.”
Community donation
An important feature of the program is its community donation aspect: every system
installed through the Electric Homes Program contributes to partner suppliers donating
systems to local not-for-profit organisations.
The 2026–27 program will launch across the region with households invited to attend an
information session in their area, ask questions and meet trusted delivery partners.
Information sessions will be held in Geelong on October 8 to launch the program, as well as Colac
on October 28 and Torquay on November 4, with future events in other towns and regions to be
announced.
The program supports residents across the City of Greater Geelong, Surf Coast, Golden Plains,
Colac Otway and the Borough of Queenscliffe.
Visit electrichomes.com.au to register for an event near you.
Geelong Sustainability is a for-purpose community organisation with a vision to build a thriving and
resilient community taking urgent action on climate change together. They deliver events, projects,
campaigns, and services to build a powerful community movement for a just transition to a net
zero future.

TRANSCRIPT
of The Sustainable Hour no. 610
António Guterres, United Nations Secretary-General: (00:00)
Cooperation over chaos. We are all in this together.
Jingle: (00:14)
The Sustainable Hour. For a green, clean, sustainable Geelong: The Sustainable Hour.
Tony Gleeson: (00:24)
Welcome to The Sustainable Hour. We’d like to acknowledge that we’re broadcasting from the land of the Wadawurrung people. We pay tribute to their elders – past, present, and those that earn that great honour in the future. In their quest to nurture both their land and their communities, the Wadawurrung people accumulated a great amount of ancient wisdom. The same kind of wisdom that we’re going to need to navigate the climate crisis, which worsens every day.
Mik Aidt: (01:06)
That’s right, Tony. And now with Bangkok ‘smashed by floods’, as the headlines went this weekend. Even to the point where Thai Airways was disrupted and had to cancel more than 30 flights. And almost a million people were affected. 32 people killed in landslides and floods in northern India. Another 10 people killed from the rains in Myanmar. And also in Mexico and Japan, they were hit by typhoons, killing in Japan it was 14 people.
And in the meanwhile, we have this all-time record-breaking overheating of the Pacific Ocean building up, which is estimated by scientists it’s going to kill half a million people in the coming months.
(Editor’s note: The researchers project 451,000 additional heat deaths from June 2026 through February 2027 compared with a normal year. Their estimate for the six months from September through February is 239,000. These are projections, not deaths already counted or a certainty that “half a million” will die in the coming months.)
And while all this disruption is happening, in this country we have two political parties who are somehow trying to convince us that there’s nothing to see here. Climate? ‘Climate is a hoax!’, and ‘renewables are bad!’ ‘They make our electricity bills go up, haven’t you heard?’
Well, actually what I heard last week is that Australia reached 80 per cent renewables in our national electricity grid. And that’s something that we should be shouting out from our rooftops folks, which a very happy Electric Viking was doing exactly that:
The Electric Viking – Facebook video clip (02:26)
Between April and June, wholesale prices for electricity were down almost half on a year earlier. Almost half. Unfortunately, there’s a bit of corruption going on here. lot of those discounted prices are not being passed on to consumers. But the grid operator says renewables and batteries are why the wholesale cost of electricity in Australia has plummeted. Australia now has more than 4 million, in fact nearly 5 million, rooftop solar systems.
A bit more than one in three homes. One of the highest rates anywhere. In fact, I believe it is the highest rate in the world. No power company built this power station. Millions of families did it one roof at a time. I get so much personal satisfaction when I hear people tell me, either in person or online, I just installed a solar and battery system or just a solar system or one of one or the other or both because of your videos or because of your advice or because of the information and it is so it is probably the most one of the most satisfying feelings in my life I’ve ever had. And here’s where it pays off for you.
There’s now so much solar at midday that the power is being given away. Since July, households in New South Wales, Southeast Queensland and South Australia can opt into three hours of free electricity every day and Victoria joins them on the 1st of October. Friday’s record landed right inside that free window. If your car’s home at midday, three free hours on a standard 7kW wall charger at around 120km or 75 miles of range, that’s free driving every single day.
Is Australia on track for 100 per cent renewables? Absolutely. It’s not a matter of if. It’s just a matter of when.
Mik Aidt (04:23)
From one of the videos with The Electric Viking (www.theelectricviking.com), who you can find on Facebook and YouTube and around in social media.
So there you go: From tomorrow, 1st of October: Free electricity coming to Victoria as well. It’s called the Midday Power Saver. And to find it well you can Google it or you can go to the Victorian government’s homepage or maybe just contact your own electricity retailer to learn more about it.
We’ll be talking about electrifying our homes in the sustainable hour today. Where we have two guests. Because at first we are going to hear an interview which I did when I was in Denmark where I met with the Danish climate cooling innovator Jesper Pedersen. And before that, as always, we must have a global outlook which is delivered by our Colin Mocket OAM and it’s kind of exciting to hear what you have picked up from around the world, Colin, even though it’s recently not been very good news. But it’s over to you, Colin. Take it away.
Colin Mockett: (05:30)
Yes, thank you, Mik. I’ll leave all the disasters to you this week because I’m starting again my roundup. This begins in New York at the UN General Assembly, where the UN Secretary General António Guterres must step down at the end of his second five year term on the thirty first of December. Now this means that there’s going to be an election among UN members to choose his successor. Unfortunately, some climate experts are already warning that several of the likely candidates could be disastrous for the planet’s efforts to tackle the global warming crisis. Their fears are that the next UN Secretary General will downgrade the priority of the crisis.
Because during his term in office, António Guterres has been outspoken on the subject. He called fossil fuel companies the godfathers of climate chaos. And he warned governments that they’re rushing down a highway to hell by failing to cut greenhouse gas emissions. But now UN watches are warning that the fossil fuel industry could fund a takeover, similar to the one that has captured and hobbled the annual COP climate talks. António Guterres, repeatedly declaring the urgency of the crisis and his willingness to take on the fossil fuel industry are credited with having had significant global impacts. He forced governments to confront their policy failures and he kept alive the aims of the 2015 Paris climate agreement.
Now this was despite a rising tide of denials and disinformation emanating from America, Russia, and other deniers. So the choice of his successor is going to be vital. And the top concerns among the scores of heads of government that met in New York this week, several of them have warned on this single issue. That’s why it’s my single issue for today.
Several of Guterres’ most likely successors have shown less enthusiasm for tackling the climate crisis despite rising world alarm at its impacts. And some of the candidates has been labelled as disastrous because they are supported by the US or its allies or fossil fuel giants or all of the above.
Three particular candidates have raised concerns the Argentinian diplomat whose name’s Rafael Grossi, who heads the International Atomic Agency, the former president of Senegal, Macky Sell, and Olara Otunu, a Ugandan former presidential candidate who has served as UN Under Secretary General for Children and Armed Conflict.
Many UN experts warn that Grossi is trying hard to be a friend of Donald Trump, along with Argentina’s president Xavier Milli, who is a climate denier. Grossi is not a climate denier himself, but those links could lead him to downplay the climate issue, said one close observer who asked not to be named. Sale is seen as a potential champion of gas in Africa as a transition fuel which many African leaders want to exploit because it has the backing of the cashed up fossil fuel lobbyists.
The same observers warned, I wonder how far he would be willing to push climate action when it conflicts with African fossil fuel energy interests. Otonio may feel national pressure on the politics of African gas and oil as well.
As Uganda has discovered large oil and gas deposits that it plans to exploit in the future. He is a very big question mark, said another observer, a different expert this time, again who didn’t give his name. Given the fossil fuel politics of Uganda, he would make climate constraints politically binding when they conflict with developing priorities. Andrea Seber, the head of political strategy at the campaign group of 350.org, said there was a definite gender gap among the candidates. All of the five women candidates range from credible to genuinely compelling, he said, while the men could be auditioning for a job description from the past century.
The men all want to be Trump, the women all want to be guitarists. The female candidates have strong climate records. Caroline Rodriguez Burkett of Guyana has also pushed strongly for indigenous rights and social development, while Rebecca Grenspan, an economist from Costa Rica, has linked the climate crisis to debt in the developing world, saying both crises need to be tackled together.
Maria Fernando Espinosa, a former foreign minister of Ecuador, led the country’s negotiating team at several UN climate COP summits. Another Ecuadorian former minister, Yvonne Abaki, has pioneered several conservation schemes, but she expressed doubts over the efficiency of emissions reductions.
One of the leading female candidates, Michelle Bachala, the former president of Chile, has said governments can no longer treat climate action as a choice, but as a necessity. But she was reported this week to have dropped out of the race mysteriously without a reason. One thing that is certain is that lobbying around the UN building will be intense over the next two months before the new Secretary General is appointed by the General Assembly that somewhere between October and December.
The new Secretary General starts work on January 1st, 2027. To most watchers from the environment movement, this election carries much more significance than the upcoming COP31 Talk Fest in Turkiye in November. The new UN chief must threaten and cajole rich countries into paying their share, and those rich countries include ours.
Even while the UN faces budget cuts of its own amid the withdrawal of US cash. Claudia Angelo of the Brazilian Climate Network said a Secretary General can only be as good as the institution they had, and the UN is currently being hollowed out by the US.
And the last word goes to Mary Robinson, the very credible former President of Ireland who now works for peace and human rights. She said we are watching the planet’s life support systems collapse around us. This could not be more urgent. The next UN Secretary General doesn’t just need to match the ambitions of previous Secretary Generals, they have to make this one of their top priorities and be a beacon of leaders all over the world to phase out fossil fuels.
I think that just about sums it up. Apart from saying that Forest Green Rovers, the Echo team, the world’s only green environmentally friendly sports club, drew away at Southern United one one this week, which left them two places higher in the table. They moved from fourteenth to twelfth, so I’ll keep an eye on them for you, because that ends our roundup for the week.
Jingle: (14:05)
Listen to our Sustainable Hour – for the future.
Tony: (14:13)
Yeah, there’s… I don’t know if ‘interesting’ is the right word, maybe ‘a tragic dance’ going on at the moment between the selection of the next UN Secretary General and then contrast that with the news that Mik referred to earlier about the amount of renewable energy that we reached recently, how that will play out?
Colin:
It it were an election at the UN, it would be much more straightforward, but it’s not. The UN you were correct in calling it a dance, Tony. It’s a political game of compromise and I what I can give you and what you can give me and it it really depends very much on the two big countries.
Unfortunately both of them are climate deniers. That’s the US and Russia. And they both hold vetoes. So they can actually stop somebody getting their job should they choose. And of course, as a background, the fossil fuel industry is being over rich and can afford to change countries’ views just by saying, we’re going to reduce the cost of fuel in your country. or we can supply more oil. I mean, they’ve probably already talking to Anthony Albanese along those lines. Because Australia will have a say in it too. Not so much a vote, as I say, but they’ll have a say in it. That’s why it’s so crucial that we get somebody of the individuality of António Guterres and as strong as Antonio has been. He has been excellent in fighting for the planet.
(CLARIFICATION: The UN General Secretary appointment process works like this: The UN Security Council recommends a candidate, whom the General Assembly then appoints.)
Mik: (16:14)
He was the the first one at that level who asked governments to declare a climate emergency back in 2019. Which was quite astonishing to see that at that time. You know, there was a grassroots movement that started here in Australia, went around the world, but actually, he took it up and made it into a global campaign.
Can I, gentlemen, can I throw into the mix here that there is another story happening? Not only is Australia reaching close to a hundred per cent renewables by now because of our individual solar panels on the roofs, coming close to five million, five million rooftops, which is amazing. But the news came out also, just last week, that Germany now has made an official policy that they are going to literally ban fossil fuels by 2045. So get completely out of oil, gas and coal in transport, in heating, in industry and the rest by 2045. That’s a goal in Germany. But it’s also coming up now in France and in Holland. So there’s a different kind of movement happening from underneath, which is not top down. It’s coming from decisions made in countries and locally. That’s what we’re seeing. We’re seeing people take action on the climate crisis. Because our politicians are failing us, and the UN system, honestly, is failing us too.
Colin: (17:40)
Look, there there’s an irony there too, Mik, in that the UN was set up in order to end wars. It’s wars that are causing the fast move to renewable energy generation now. The reason that Germany and France and the Netherlands are moving that way is because they previously used to rely on Russian gas especially Russian gas and oil, and the quicker they give up – they’ve got that embargoed because of Russia’s walking into and declaring war on Ukraine.
The reason that we in Australia are taking up electric vehicles at a very fast rate isn’t because we’ve all suddenly seen the light and decided that we’re going to be environmentalists, it’s because the price of petrol is going up to somewhere like three dollars a litre.
And so people are saying we’re not gonna pay it. We’re not going to be hostage to Middle Eastern conflicts and things like that. We’re going to buy electric vehicles where we don’t have to put fuel into them and we want our government to switch very quickly to clean energy generation so that we don’t have to worry about importing gas or using our own gas. We don’t have to worry about burning gas, coal or oil.
Mik: (19:10)
And the ridiculous amount of money that our government is paying to fossil fuel companies in this rebate. You know, billions of dollars in rebate. That’s our taxpayer money which is being spent on these companies. There’s been quite a bit of talk about that because Andrew Forrest, the leader of the big iron ore company Fortescue, has been in the media. He was in New York being interviewed by the ABC and and talked, I thought, rather brilliantly about the absurdity that we have to fund these fossil fuel companies with so much money. It’s just absurd.
David Speers – ABC video clip: (19:50)
The diesel fuel rebate, you’ve been campaigning for some time now for that to be wound back considerably. The big beneficiaries are the big mining companies, including your own. How’s that going, that that push?
Andrew ‘Twiggy’ Forrest: (20:02)
Yeah, look, I think it’s gonna be looked at as you know, and I wish we weren’t being recorded right now because for anyone to support the diesel fuel rebate above 50 million dollars, you’re really taking the piss. I mean it’s not an expression I like to use in polite company. I looked up before I walked in: How can how else can I say it? And it said, ChatGPT came up and said, try: ‘They’re mocking the Australian public’. Okay. They’re treating the Australian public like idiots. You know, they’re covering with smoke and mirrors and light what they’re actually doing, which is ripping billions of dollars out of mums and dads to prop up a diesel consumer which is bidding against mums and dads at the bowser.
David Spears: (20:48)
It would cost you several hundred million dollars to cap the rebate at fifty million each, it would cost I think BHP and Rio, Tinto much more. why do you want to give up that rebate?
Andrew Forrest: (21:01)
Because it’s bad for our planet, it’s bad for our country. And it’s directly why you look at the 640-50 billion – sorry: million dollars, let’s go look at this, across the world, and then you look at the cost of the extra cost of diesel since the Strait of Hormuz, and the biggest consumer and loser has been Australia. And that’s on diesel because the mums and dads through this ridiculous mocking diesel fuel rebate to big companies who are just taking it for the hell of it, are subsidised by mums and dads to only buy diesel. They’re not subsidised to build their own green energy systems, they’re not subsidised to do anything else. They’re subsidised by the government and therefore the taxpayer to buy diesel in the bowser against mums and dads. Just ridiculous.
David:
And it would mean those BHP and Rio Tinto would have to seriously consider moving into the sort of electrification and renewable powering of of their operations in the way that you have. You obviously know, you’ve got the lead on them when it comes to that.
Andrew: (22:15)
Yeah, but for how long? I mean, this is this is almost perfect competition in the government is paying these companies to not move and no one likes to hear that, but you’re paying the biggest companies in Australia to not innovate. And it’s costing your taxpayers terribly. And that’s why I say the diesel fuel rebate and those who defended over fifty million, they’re mocking the Australian public.
Mik:
And this is what the Labor government is allowing – you know, year after year after year we’re seeing this happen. Anyway, there are elections on their way.
And can I just say the petrol price in Denmark, if you think it’s bad with three dollars per litre, in Denmark citizens are paying four dollars per litre at the moment. Because it’s also quite heavily taxed and so on. So you can imagine paying four dollars a litre. People feel it heavily and consequently, as you’re saying, the sales are now almost close to a hundred percent. There is not a single petrol car being sold anymore in Denmark. They are all electric.
(CORRECTION: In Denmark, electric cars made up 85.6 per cent of new car registrations in August 2026. Petrol and diesel cars were still being registered.)
So anyway, I’m thinking today we could make a another trip back to Denmark. I did go out sort of in the outback of the Danish bush when I was there to meet Jesper Pedersen – someone who is sort of the merge between an engineer, an inventor and a scientist, someone who knows a lot about fridges. That’s actually his job in his day to day – he is working with fridges. And he has an idea, a big idea of how we could use some of that technology in cooling down our planet.
Jesper Pedersen: (23:58)
Yeah, I’m educated as a marine engineer and it is 12 years since I graduated from Fredericia. And since then I have worked with the refrigeration, the industrial refrigeration solutions. And also I’ve worked in a naval architect company. So I’ve spent a lot of time with the engineering, how we design plants, refrigeration plants and how we can engineer machinery in an efficient way.
So I know how to design components and many kinds of solutions. And two years ago I came up with this climate repair project and spent a lot of time how we could potentially cool the planet and what kind of factors that affect the temperature on the planet.
And I quickly figured out that the Earth’s mean average temperature is not only controlled by the CO2 concentration in the atmosphere, but also the albedo value. The amount of clouds on the planet has a huge impact on the temperature. And I know a lot about the Mollier diagram and how we can humidify the air.
During the humidification process, can also cool the air using a small amount of water, which actually cools the air immediately. So I begin to figure out, can this concept be used as a climate repair solution? If we increase the amount of clouds on the planet, it could reflect sunlight back into space.
I have seen a video where David Keefe mentioned that we should reflect around 1 per cent of the energy from the sun should be reflected back into space. And that is equal to an area of 5 million square kilometres. The area where we should try to redistribute the cloud formation and ideally we should increase the amount of cloud formation very evenly all over the planet.
So maybe around 1 to 2 percent of the sun’s energy should be reflected back into space in order to stabilise the climate on the planet.
Mik: (26:38)
So yes, but what you’re talking about is what we hear about often mentioned as ‘geoengineering’, isn’t it? That we humans begin to alter the climate in a sort of a technical or even a chemical way. And we also hear a lot of criticism on doing that because you know, what could go wrong?
Jesper: (27:02)
Yeah, exactly. So yeah, we don’t know the exactly feedback of, let’s say, if we do stratospheric aerosol injection at scale, what kind of consequences could that have on the on both on the local climate where it could have a potential pollution impact on the local climate, but also how it will affect the weather pattern, how participation will be affected of that kind of chemical solutions. So I think that if we humidify the air with nozzles that are mounted on a wind turbine and get the energy from a wind turbine, that could actually be a very sustainable type of geoengineering.
Mik: (27:54)
What would that look like? I mean, what are we talking about here?
Jesper: (27:58.434)
Yeah, we are talking about a wind turbine that, say it has a tower of 100 metres and then we have a spray beam, two spray beams that reach an area or affect the area, let’s say 100 metres in width and with a height of 100 metres then it affects an area of 10,000 square metres.
And if the wind speed is, let’s say, 10 metre per second, then it could affect millions of cubic metre of air per hour, where it could cool this amount of air and actually send colder air, let’s say, over a night 500 kilometres away from the wind turbine. So it could affect a huge area with the increased moisture and the…
During the night, the Earth acts as a dehumidifier where this increased water vapor is actually removed from the air again. And the next day when the Sun goes up, this increased moisture in dry areas will re-evaporate again and then actually convert the Sun’s energy from sensible heat into latent heat and thereby increase the cloud formation. That is…
One feedback loop, I could see that it could increase the precipitation in desert areas. That is how I see it.
Mik: (29:30.378)
I saw some pictures from China during the latest heat wave where they sprayed out water from skyscrapers and sort of created a kind of cloudy, misty atmosphere around the houses. And apparently, you know, that saved people from dying from the heat anyway. Is that what we’re talking about?
Jesper: (29:49.39)
Yeah, it is a similar concept, unfortunately we don’t have skyscrapers or high towers in all areas. So that kind of solution will be limited to the big cities and we need to find a way how can we affect the climate in an area equal to 1 or 2 % of the earth’s – an area like Australia, we need to evaporate water into there.
Mik: (30:24)
If you have it your way with your project, what would that look like? For instance in Australia. Can you give us a vision of what your project would look like if it was successful?
Jesper: (30:36.098)
Yeah, if it was implemented at scale, I could see that it could be introduced in a big area, in a line where we will investigate the wind direction. And then we will have some kind of mist wall where plenty of wind turbines is standing beside each other. Let’s say 100 wind turbines creating a mist wall. it affects only, let’s say, in 500 kilometres behind the wind turbines but also let’s say it is 10 or 20 kilometres beside each other and then it could cool the air in a very huge area. So of course we need a lot of wind turbines with this technology implemented but again, compared to the, let’s say if one wind turbine can affect the area behind the wind turbine, around 500 kilometres away, then it could actually have a huge impact. And then 500 kilometres away in that line, you can have a next section of wind turbine with the technology. That could be one, I would say, way to use the concept.
Mik: (31:57)
We hear a lot about that because of global warming the air can hold more moisture. Seven per cent more per degree. And that is a problem because that is what’s causing more dangerous hurricanes and so on. You know, when the ocean gets warmer, it evaporates more water and that creates cyclones and hurricanes and lots of devastation and problems. So could there be some unforeseen similar problems with your idea, you know, getting all that moisture up in the air?
Jesper: (32:31)
Yeah, I like the question actually. Actually, the problem is that if you have a very dry area where a lot of the sun’s energy is converted into sensible heat energy, then the temperature accelerates very quickly. And because of that, that air can hold more water vapour. And the average lifetime of water vapour on the planet is around eight to nine days. Let’s say that lifetime could be shortened to seven days That means that the water vapour will be removed. They are very quickly or faster and also the average cloud altitude is also has also a big part of that the average cloud altitude is around five kilometres and if that cloud average altitude could be lowered a little bit
Let’s say with 200 metres, then the clouds could actually have a cooling effect because high clouds have an overall warming effect and low altitude clouds has an overall cooling effect. And actually fog or very what can call, when the air is dry and precipitation happens, then you have this adiabatic cooling effect where the temperature drops very fast.
And during nighttime, the earth acts as a dehumidifier where the dew point is reached. So if you have a lot of moisture in the air before the sun goes down, that area will… more water vapour will be removed during the night. So the time the water vapour will stay in the atmosphere because of this humidification will only be overnight actually., and then it will re-evaporate the next day in the dry areas. And if the temperatures can be kept at a low temperature, then the amount of water vapour the air can hold is lower than air temperature at a higher temperature. That amount, the absolute humidity can be read in Moller’s diagram.
Jesper: (34:57.045)
I think it is around 10 degrees centigrade is around 6 gram per kilo dryer and at 40 degrees centigrade it is around 50 gram of water vapour per kilo dryer. So there’s a huge difference between how much water vapour they can hold. Actually snow formation can actually happen if the temperature is up to plus three degrees centigrade, before precipitation and let’s say then you have some rain that falls through dry air and then the temperature drops below freezing point and then you have snow formation. So you have actually this kind of adiabatic cooling already takes place naturally in areas where we have the optimal water cycle. But in dry areas, the sun’s energy is converted into sensible heat. And that means higher temperature.
Mik: (36:03.712)
So what’s the cost of a project like what you’re talking about?
Jesper: (36:08.458)
I would say it is a, since I have not investigated all the costs, of course, I think the additional cost for the wind turbine will, I think, I guess would be 20 % higher than a standard wind turbine. But then you have the irrigation pipe and where should you get the water from? If it is salt water and you want to convert it into fresh water, then you need a desalination plant.
I think in Israel they have plenty of that type of desalination plant to get tap water or drinking water. So of course it will not be for free to implement these solutions. But in the other hand, what is the cost if we don’t do something about global warming? What kind of consequences or feedbacks does that have?
That is also important to have in mind. How much? Yeah, of course. And then you also have a lot of people who die because of heat. And if we can minimise or lower that risk, then I think it will benefit everyone on the planet. That’s how I see it. So currently it will be difficult to say, let’s say it costs $100 billion to implement. That we are not in that phase or in that step yet. We need to investigate. We need to collect data from real field experiments before we can estimate the rough cost of this solution.
Mik: (37:58.595)
So what’s the next step for you? What’s happening next?
Jesper: (38:03.704)
Currently I’m trying to get funding for this project. So next step would be to get funding, whether it is a public funded program or a private funded program. But I think if we should carry out real field experiments, we need some kind of government approval that, okay, you are to do this field experiment at small scale in a small area. So this kind of technologies can’t be implemented without the politicians decide that we should try to minimise global warming.
Mik: (38:52.468)
So when you have been to these conferences about climate rescue one way or the other, has there been other solutions up that that seem promising and that are in a way competing with your idea?
Jesper: (39:07.438)
Yeah, currently there’s marine cloud brightening. is, think actually this evaporation cooling is a type of spin-off of the marine cloud brightening test when they have carried out them. So, yeah, in some way marine cloud brightening is a direct competitor. Then there’s ice thickening where they pump water on top of the sea ice to grow more sea ice during the winter. So the additional sea ice lasts longer in the spring period and reflects sunlight. But I would not say that it is a competitor because, okay, let’s say we can install 100,000 of my wind turbines combined with 100,000 ice thickening units. I think the problem is so big with global warming that seeing each kind of technologies as a competitor is we are in the in the early startup phase everyone so, so I don’t think we are currently seeing each other as a competitors. I think maybe in 20 years we will have collected data what kind of solution is the most sustainable solution what kind of concept is the most efficient solution. How many units will this technology require over another technology? As I am aware that stratospheric aerosol injection is one of the, what can you call it, easy fix solution if you ask the professor, but no one has done that kind of concept at scale. So we simply don’t and not have data to conclude anything yet.
Mik: (41:04.938)
And that is maybe also the scary one, isn’t it? just to explain for our listeners, where what you’re talking about there is where chemicals you could say are sprayed out from an airplane and that has an effect on the amount of clouds that there is over an area. the problem there being let’s say something went a little bit wrong there and the weather really changes and the harvest went wrong in the countries underneath and it wasn’t the not the same country who had sprayed who suffered the consequences and so on. It seems like it could easily be unmanageable. Or how do you see that?
Jesper: (41:43.598)
Yeah, I agree with that, that it could easily be sold as an easy-fix concept, but when it is tried to be done at scale, many other feedbacks is… Maybe we will realise that it also have a lot of negative feedbacks. And another thing is that some professors have suggested that we should try to do SAI in the polar area.
In the cold area where the sun intensity is not so high, think the better area or more efficient area is actually in the tropical areas where you don’t struggle with melting ice but over time it will also affect the polar areas to reduce the amount of melting water and lower the temperature in that areas.
I think that the most promising solution in the Arctic areas is actually ice thickening concepts. That is the most efficient solution for that area. My concept could also be used in the polar areas, but then it would simply be a big snow cannon. So I think this solution is very…
The humidification concept is most promising in Australia, in Africa, in South and Europe. It could also be used in Denmark, US, all kinds of… I think the Death Valley, which is the hottest place on the Earth, the temperature there could be lowered from around 50 degrees centigrade to 20 or 25 degrees centigrade.
It could have a huge impact in that kind of areas.
Mik: (43:44.462)
These were the words who came from a Danish refrigerator and engineer expert who has some big ideas for how we solve the climate crisis. Thank you very much for you know at least sharing with us your ideas at this point and we will be following you on your journey and wish you really wish you good luck with it and hopefully some something powerful could come out of this.
Jesper: (44:14.126)
Thank you very much, Mik. It was a pleasure to be here doing this interview. I’m also looking forward to see where we are within one decade or something. I expect that the climate repair technologies will be much more well known for the public, let’s say, if we meet in 10 years or so.
Mik: (44:41.024)
If people are interested in knowing more about your work, where do they find you?
Jesper: (44:45.228)
They can find me on LinkedIn and on my webpage www.jpclimatec.com. That is where I share my own research material.
Mik: (45:01.4)
Great, we’ll put a link out to that as well in our shownotes on climatesafety.info.
Colin: (45:13)
Did you know, Mik, that the refrigerator was invented in Geelong? By James Harrison, who was editor of the Geelong… or owner and editor of the Geelong Advertiser. He used the old letterpress method of printing. He cleaned down his metal plates at the end of each edition, and he noticed that the chemical he was using made the metal plates cold. So he thought if I can just trap that and put it into a pipe and then put it into a coil, I can make ice. That’s what he initially wanted to do was to make ice. But what he did is he invented refrigeration. The base of every fridge is that coil of chemicals.
Different chemicals these days, of course, because the old ones harm the planet. But it’s the invention. If you find his grave in the Geelong Cemetery, he’s got two headstones or he’s got two plaques on his on his grave. One of them is tells you who he was and he was the editor and owner of the Geelong advertiser and founder. And the other one was put there by the refrigeration industry. A delegation came from Detroit of all places and called him the father of refrigeration.
Mik: (46:34)
And when was this?
Colin: (46:36)
In the 1860s to the 1880s, by that time we were exporting frozen meat, frozen lamb.
CORRECTION: Harrison developed his refrigeration system in Geelong in the early 1850s and patented it in the mid-1850s.

Tony: (46:55)
Our guest today is Lucy Allinson. Lucy is the program manager at Geelong Sustainability. So Lucy, thanks for coming on. Welcome to the Sustainable Hour. We understand you’ve got a big event coming up at the moment, so maybe we can talk about that.
Lucy Allinson: (47:16)
Yes, no, we’re really excited, Tony. Geelong Sustainability’s Electric Homes Program is back for 26-27. This will be the fourth year that we’ve run this. And it’s a really powerful community program. Over 750 households here in the region have used this trusted program to help make their homes more comfortable and their energy bills more affordable.
And we’ve got a big launch coming up on the 8th of October down at the waterfront at Deakin. And we really encourage householders to come and learn a little bit more about what they can do in their own homes and meet some of the trusted suppliers that we’ve vetted here for the region and learn about some of the upgrades and retrofits that will really help them be more comfortable and have less costs to run their home.
Mik: (48:12)
I appreciate the word trust, Lucy, because it’s very difficult when you begin looking into this, who should I call and as you say, who can I trust?
Lucy: (48:22.35)
Absolutely, and you know one of the biggest barriers to this, it’s complex upgrading your home. There’s many things that you can do and you know that every home is slightly different and has its own individual requirements and the journey of understanding what you need to do in your home, which upgrades make sense for you, and then trying to find who can do them for you is not easy and that’s what we’re here to help for.
You know, we will provide these information sessions. You can either have an audit done for your home, which helps you understand the many choices you have, or you can just, you might know what you want to do, but you just don’t know who to do it with. And so we’ve gone through this journey and we’ve got a slightly improved model this year on previous years in that we have multiple suppliers for each upgrade so that every householder has a choice and can get several quotes, keeps everyone competitive, gives you more choice and we really think it will add value to what is already a very successful programme.
Colin: (49:27)
Lucy, did you personally use the system when you upgraded your home or did you do it by yourself?
Lucy: (49:37)
So I’ve been in this sector for a very long time. I’ve been running sustainable homes programs for government, community, all over Victoria. So I was quite well informed on what to do. I have upgraded my home. I got to just under 8 Star. I had to deal with a very old house that needed insulation and window upgrades and many, many things. I now have an all-electric home. I have managed to afford to put solar on the roof. So having the electric appliances, it now means that I can actually have solar, more efficient, cheaper energy to run those electric appliances. And my costs to run my home are marginal. And I’m rather pleased with myself, if the truth be known, because it’s not an easy journey. you know.
I really recommend just take one step on this journey. You don’t need to conquer it all in one go, but just have a look at either your hot water system or just your insulation and we’ll help you on the way to find the best way to do it.
Colin: (50:44)
Great. Have you got a battery?
Lucy: (50:47)
I have. I ended up with a 10 kilowatt battery. There are so many variables to every decision, the sizes you choose, the brands you choose. And that’s why we have this choice of suppliers who know their business, who we have vetted around pricing and service delivery, you know, who will guarantee their warranties. And you can feel that, you know, that you are making a decision with somebody who knows their business and is here for the long term. And that’s what we’re trying to take away that worry for the householders in our region.
Colin: (51:25)
Great. And you retrofitted an old existing home. So which element did you do first?
Lucy: (51:34)
I did quite a lot of it together at the same time but one of the first things I always think about is the insulation in the roof because if you’re going to adjust your heating and cooling it’s really powerful to try and have some constraints to your thermal shell that keep the heat or the cool in there. The other one that’s always a very good straightforward starting point is your hot water system. The savings are substantial.
You can have a really evident success in a payback and a return on investment on your hot water system without having to worry about multiple other effects. But every house is a little bit different. Some people are ready to just go straight for solar. But I think, you know, that journey is where we can help our householders by having an audit because that audit helps people understand what all these things are and where they might prioritise.
Mik: (52:35)
So the last time Geelong Sustainability ran this program, you say seven 720 houses were actually upgraded as a result. Did you make a report? Do you have some findings, some statistics on you know what did people invest? How much did they pay? In numbers, what were the outcome from that 720 house experience?
Lucy: (53:00)
Yeah, absolutely. We have multiple stakeholders who help us in the community. We have our councils, obviously the suppliers. We even do some research on the back of this. So we do try and gather the statistics that help us understand the success we’re having and how we can improve further. And so the data, perhaps the most significant data might be that together on an annual basis across this program for our householders in the community. We’re saving $445,900… I think just under $446,000 annually across all the households as a result of this program. And obviously those savings accrue over year after year up until the life of the appliance has to be replaced.
The amount of saving for not only our householders but our broader community here is substantial and it’s really important to understand. One of the other wonderful things of this program and we thank our suppliers and our stakeholders for this is every contribution and upgrade that our householders do within the Geelong Sustainability Electric Homes program, we get a donation that goes towards those householders or those community facilities that don’t have the capacity to add solar to their roofs or improve their hot water system. And we’ve had multiple donations over the life of this program to help our community houses and those that need it most.
Mik: (54:40)
I was going to ask because personally I’m a renter and it sounds to me this is the program only for house owners?
Lucy: (54:48)
The renter sector is way more difficult because you do have this need to get approvals from your landlord, yet the landlord doesn’t always get the benefits that you’re seeking. So that’s always been a challenge in the rental space. There are still things you can do which are quite accessible like draft ceiling. Draft ceiling is one of those really important upgrades that just gives you a level of comfort. It may not have dramatic impacts on the bill, but it will certainly help control the heat or cooling in your environment. And you can zone off areas of your house. There are things that you can do. And we continue to work to try and drive initiatives for renters. But certainly, this is easier for the homeowners to take a bigger step without them.
Colin: (55:39)
It’s also easier, Lucy, because your program runs through the summer. And if you’re changing your heating, for example, it’s much, much easier to do it during the warm weather than during the winter. But what you really have to do is to say to the people of Geelong, remember the winter that we’ve just been through. You will be warmer and cosier and much richer if you change your heating away from fossil fuel.
Lucy: (56:12)
Absolutely. The appliances that are accessible to us now, reverse cycle air conditioning, these are very efficient. They use a heat pump technology that can give us up to four times efficiency on our energy use. And they not only keep you pretty warm in the winter, but they also give you that added benefit of being able to cool your house in the summer. So they are multifunctional and they are way more efficient.
Whichever season you might be in, and yes, never let’s forget how cold it can be in the winter, but it’s also getting incredibly hot sometimes in the summer. And just being able to control that environment where you want to be comfortable is really important. And these energy efficient appliances are really significant. And then if you can add solar to the back of that, you get a cheaper form of power source, then you’ve saved yourself a lot of money.
Mik: (57:09)
Can I just remind you that in Europe people have gone through a summer just now where 35,000 people – an excess of 35,000 people died because of the heat. So the heat is not just about comfort, it’s actually also about protecting especially vulnerable people like babies and elderly people.
Lucy: (57:31)
Absolutely. It’s an increasingly concerning area. It’s particularly where we have two or three days of continued heat wave and the house isn’t cooling down overnight. These have terribly big health impacts for our vulnerable at extreme ends of our ages. And I think if we’re talking health as well, we must highlight that some of the additional benefits to electrifying your home is that you take gas cooking out of your home.
And there are some real health benefits around asthma and improving things for safety for both our elderly and our children. there are so many multiple benefits that come with electrifying your home that it is a really important part of keeping yourself healthy, but also driving a more affordable option for yourselves.
Tony: (58:23)
Lucy, there’s it we’ve spoken about the obvious benefits and the savings that there, but a lot of people are put off by the costs of doing this, of of of doing the conversions because they don’t have the money up front. Is there any.. do you get any support from financial institutions to enable that or government grants to enable that to happen?
Lucy: (58:48)
Absolutely. Yeah, look, is a one key barrier we talked about with the suppliers, which we’ve tried to support. The other is finding that upfront investment to actually, even though we know it’s got a good return, where does the money come in the first place? And there’s several ways you can tackle that. Basically, know, sometimes you need to replace your appliance at end of life regardless. And if that’s the case, your hot water, for example, know what you want. When it does die, go get the right one because you’ve got to then live with it for the next 15, 20 years. So know what it is that you want to replace it with. That’s something you would have to find financially anyway. But yes, rebates are really important part of this area. Batteries are really big on their rebates. We’ve now got the Victorian energy upgrade sector supporting insulation upgrades in the roof space. We have a whole bunch of efficient appliances, small appliance certificates that help us get money to reduce the cost. So that’s helpful. We have a loan out of Solar Victoria, $1,400, to help us with the installation of solar. And we do have some efficient finance through some of our suppliers who will help you find a way to find that financial support at a reasonable rate so that you can invest and then get that payback on that investment.
Tony: (01:00:17)
So it it really is a one stop shop that you’re providing.
Lucy: (01:00:22)
Absolutely, I mean we’re doing it across a whole range of suppliers, but every house is a little bit different and across the whole range of upgrades everyone’s going to want something different, so we are offering all those upgrades to the householders with a multiple choice of suppliers so there’s going to be something in there for everyone who wants to look at improving their home and their comfort.
Colin: (01:00:47)
Does Geelong Sustainability have a charge for this service? That’s my first question. The second one is if somebody is interested, how do they get in touch with you?
Lucy: (01:00:59)
They don’t have a charge and for that we thank both our supporters like the City of Geelong, Surf Coast, Queenscliff, Colac. These shires have been very helpful in supporting their regions and this program and of course the suppliers themselves are providing very competitive quotes so there is no charge to the householder.
And the way to find out about it is you can go to our website, www.electrichomes.com.au and you will find come October there will be an expression of interest in there and you can request quotes on different services of interest to you. Or perhaps in advance of that what I would recommend is you find an event near you and you go and listen to the services and ask all the questions you want of people who have the answers for you. And the big main launch that we have here for the whole program is going to be in Geelong on the 8th of October down at the waterfront at Deakin. And I’d really recommend you come along. If you go to the website, look under the events tab, you can register for it there and come and ask all your questions.
Mik: (01:02:20)
Lucy Allinson from Geelong Sustainability, it’s been a wonderful Sustainable Hour with such good news for people, you know, hundreds of people who can now thanks to your program start, find the courage to get started with upgrading their homes and and becoming fully electric. What a great job you have, Lucy. You you must be quite pleased with with the work.
Lucy: (01:02:45)
I feel very honoured to even be part of this program because it really is doing a lot of good for the community.
Mik: (01:02:52)
We’re certainly all smiles here in in the team of The Sustainable Hour. So all the best with the program and we’ll be there on the 8th of October, you can count on us. Can I just ask you now, this is a challenge: We always end our program with saying be the something, ‘Be the change’, ‘be the difference’, ‘be electric’. What should we be, Lucy?
Lucy: (01:03:14)
I think in a modern world where we are all under pressure financially: Be wise. Think ahead.

SONG (01:03:24)
‘Starting From Today’
Verse 1:
Looking at your face right now
As you scroll through the headlines
I see the worry in your eyes
About the world we leave behind
And I know you’re wondering
If anyone will make it right
But baby, let me tell you something
That keeps me up at night
There’s still time to change the way
Things are going day by day
And when you feel like giving up
Remember what I say
Chorus:
I can be that difference
I can be that change
I can be that difference
Starting from today
Verse 2:
Dad, I’ve seen the videos
Of how things used to be
Clear skies and clean waters
It’s hard to believe
But I’m not just sitting here
Waiting for a miracle
Got my friends beside me now
We’re making it possible
Every small step counts, they say
Little changes pave the way
When it seems too much to bear
Listen close, I swear
Chorus:
I can be that difference
I can be that change
I can be that difference
Starting from today
Bridge:
We rise together
Hand in hand we’ll find a way
We rise together
Every choice we make today
Shapes tomorrow’s way
Chorus:
I can be that difference
I can be that change
I can be that difference
Starting from today
Outro:
We rise together
Starting from today
