Since 2015, Australia has added 40 GW of new rooftop solar panels and large-scale renewable energy projects.  

It has increased the share of renewable energy in the country’s power system from 16% in 2015 to nearly 40% in 2024.   

But how will energy efficiency fight climate change for 2025 in Australia? With renewable energy, of course!  

With the shift to renewables, emissions in 2024 are 30% lower than they would have been if Australia had stuck with the older power plants from 2015. This change has prevented over 200 million tonnes of CO2 emissions since 2015.   

By the end of 2025, renewable energy production is expected to be three times higher than in 2015, making up about 48% of all electricity generation. 

What is Climate Change?

Climate change means the long-term changes in the Earth’s weather patterns and temperatures.  

While the climate has naturally changed over thousands and millions of years, the climate change we see now is happening much faster because of human activities.   

When we burn fuels like coal, oil, and gas to produce energy, they release greenhouse gases.  

These gases, such as carbon dioxide and methane, trap heat in the Earth’s atmosphere, making the planet warmer. It is known as global warming, which is one part of climate change.   

But climate change isn’t just about the Earth getting hotter. It causes all sorts of changes to the weather. For example, some places might experience more frequent and stronger storms, while others may face longer droughts or heavy rainfall, leading to flooding.  

The ice in the polar regions is melting, and sea levels are rising, threatening people living in coastal areas.   

Plants, animals, and even humans are affected by these changes. Some species might lose their habitats and struggle to survive, while farmers could find it harder to grow crops due to unpredictable weather. 

These effects also create social and economic challenges, as communities may need to move, repair damage, or deal with food shortages.   

The good news is that we can slow climate change by making better choices, such as using renewable energy sources such as wind and solar power, planting more trees, and reducing waste. 

The Effects of Climate Change in Australia

climate change

Climate change is having a big impact on Australia, and people, animals, and the environment all feel the effects. The country is known for its hot and dry weather, but climate change makes it even more extreme.   

One major effect of climate change is the rise in temperatures. Australia has been experiencing more heat waves, with some days becoming dangerously hot.  

It makes it harder for people to work or even stay comfortable, and it can be very harmful to the elderly, children, and those with health problems.   

The increased heat also makes bushfires more frequent and severe. Australia has always had bushfires, but they are happening more often and burning longer. 

The bushfires destroy homes, forests, and wildlife, creating a lot of smoke and unhealthy air.   

Another effect of climate change in Australia is drought. With less rainfall in many areas, it becomes harder for farmers to grow crops and care for their livestock.  

This affects the food supply and the economy. In contrast, some parts of Australia have been getting heavy rains and floods, damaging homes, roads, and businesses.   

The oceans around Australia are also feeling the effects of climate change. The water is becoming warmer, which harms the Great Barrier Reef.  

Coral reefs are very sensitive to temperature changes, and they have suffered from coral bleaching, where the coral turns white and struggles to survive. It is bad for marine life and tourism, as many people visit Australia to see the reef.   

Rising sea levels caused by melting ice around the world are another concern. Coastal areas in Australia are at risk of flooding, and some communities may need to move to higher ground in the future.   

Animals in Australia are also struggling. Changes in the environment are causing some species to lose their habitats.  

For example, koalas are finding it harder to live in hotter conditions, and some birds and fish are being affected by changes in water availability and temperatures.   

These effects show that climate change is already making life harder in Australia. While the challenges are serious, there is hope.  

By reducing greenhouse gas emissions, protecting the environment, and using more renewable energy, Australia can work to minimise the damage and adapt to the changes ahead. 

While it’s a big problem, every small effort counts in protecting the planet for future generations.  

How Energy Efficiency Will Fight Climate Change for 2025 in Australia: A Guide by Cyanergy

Energy efficiency means using less energy to do the same job, like lighting your home, running appliances, or powering businesses.  

It’s one of the best ways to fight climate change because it reduces our energy needs, which means burning less coal, oil, and gas.  

These fuels release greenhouse gases, which trap heat in the atmosphere and warm the planet. 

Here’s how energy efficiency can make a difference in 2025:

Lower Carbon Emissions

Australia can reduce carbon emissions by improving energy efficiency in homes, buildings, and industries. For example, energy-saving light bulbs, better insulation, and energy-efficient machines can reduce our electricity.

More Renewable Energy

If we use less energy, relying on renewable energy sources like solar and wind is easier. This reduces the need for fossil fuels, the biggest contributor to climate change. 

Saving Money

Energy efficiency isn’t just good for the planet but also for people’s wallets! When Australians use less energy, their electricity bills go down. Businesses can also save money by upgrading to energy-efficient equipment.

Healthier Communities

Less pollution from burning fossil fuels means cleaner air and better health for everyone. It is especially important in cities where air pollution can be a big problem.

Job Creation

Investing in energy-efficient technologies creates jobs. For example, workers must install solar panels, upgrade insulation, and develop new energy-saving products. 

Australia has already made progress with energy-efficient policies and programs, and in 2025, it will continue to play a key role in reducing emissions and fighting climate change. Everyone can contribute to a greener, healthier future by making smarter energy choices.

Climate Resolutions for 2025 By Cyanergy

Cyanergy is aligned with The Climate Council and emphasises the urgency of addressing climate change, especially with the upcoming federal election in the first half of 2025.  

To further reduce Australia’s climate pollution and influence national climate action, we suggest the following resolutions: 

Take Collective Action:

Engage in community-led initiatives such as petitions, protests, or contacting local Members of Parliament (MPs) to advocate for stronger climate policies.  

For instance, signing open letters that call for doubling Australia’s rooftop solar capacity by 2030 can significantly impact.  

Move Your Money Away from Fossil Fuels:

Ensure that your bank accounts, superannuation funds, and investments do not support coal, oil, or gas projects. Opt for financial institutions that prioritise renewable energy and environmental sustainability.  

Change How You Get Around:

Since personal transport is a rapidly growing source of climate pollution in Australia, consider alternative modes of transportation. This includes using public transport, cycling, walking, or transitioning to electric vehicles to reduce emissions.  

By adopting these resolutions, individuals can contribute to a collective effort to combat climate change and encourage policymakers to implement more proper climate actions.  

What are Australia’s Climate Change Strategies for 2025 and Beyond?

Australia has developed comprehensive strategies to address climate change, focusing on mitigation and adaptation for 2025 and beyond.  

Key components of these strategies include: 

Mitigation Efforts:

Upgrading the Electricity Grid: Australia is upgrading its electricity infrastructure to support greater integration of renewable energy sources and increase the share of renewables in the energy mix.  

Promoting Electric Vehicles (EVs): Efforts are underway to reduce the cost of EVs and encourage their adoption, thereby decreasing emissions from the transportation sector.  

Supporting Industry Innovation: The government is assisting businesses in adopting advanced technologies and smarter practices to lower their carbon footprints.  

Encouraging Emission Reductions: Both businesses and consumers are motivated to implement measures that reduce greenhouse gas emissions.  

Regulating and Reporting Emissions: A framework is in place for controlling and transparently reporting greenhouse gas emissions to ensure accountability.  

Agricultural Sector Initiatives: Programs are designed to help the land and agriculture sectors reduce greenhouse gas emissions.  

International Partnerships: Australia is collaborating with Indo-Pacific neighbours to work towards emission reductions collectively.  

Adaptation Strategies:

Protecting Natural Resources: Measures are in place to safeguard species and manage natural resources, ensuring the environment can withstand and recover from climate impacts.  

Infrastructure Resilience: Upgrades to buildings and transportation systems are being implemented to enhance their resilience against heat waves and extreme weather events.  

Supporting Vulnerable Populations: Initiatives focus on the well-being of Australians most affected by climate change, particularly those facing increased natural disasters and severe weather conditions.  

Key policy documents outline these strategies, including the National Climate Resilience and Adaptation Strategy 2021–2025, which positions Australia to anticipate, manage, and adapt better to climate change impacts.  

The Climate Change Action Strategy (2020–2025) also guides the Department of Foreign Affairs and Trade in integrating climate considerations into its operations and international engagements.  

Paris Agreement Commitment

The Paris Agreement is a global treaty adopted in 2015. It aims to limit global warming to below 2°C, preferably to 1.5°C, compared to pre-industrial levels.  

2030 Target: Initially, Australia committed to reducing greenhouse gas emissions by 26-28% below 2005 levels by 2030.  2022, this target was updated to a 43% reduction by 2030.  

Net Zero by 2050: Australia has set a goal to achieve net-zero emissions by 2050, aligning with global efforts to mitigate climate change.  

In September 2022, Australia’s Climate Change Bill became law, formalising the nation’s emissions reduction targets and requiring annual climate change statements to monitor progress.  

As a party to the Paris Agreement, Australia collaborates with other nations to address climate change challenges, sharing strategies and technologies to achieve common goals.  

While Australia has made progress, achieving the Paris Agreement’s objectives will require continued policy development, technological innovation, and societal commitment to meet and potentially exceed current targets.  

Australia aims to effectively mitigate greenhouse gas emissions and enhance resilience to climate change’s ongoing and future impacts through these comprehensive strategies.

Matthew Stead: [00:00:00] The Uptime Wind Energy podcast, brought to you by StrikeTape. Protecting thousands of wind turbines from lightning damage worldwide. Visit StrikeTape.com. And now, your hosts

Allen Hall: Welcome to this edition of the Uptime Wind Energy podcast. I’m Allen Hall here with Matthew Stead, Rosemary Barnes, and Yolanda Padron. And our week starts off in the courtroom. And if you’ve been watching the news lately, there’s a pretty substantial IRS case involving large-scale wind and solar having to do with the, uh, production tax credit and, uh, investment tax credit at the same time on the safe harbor, 5% safe harbor rule.

Uh, a federal judge handed the wind industry and solar industry a pretty substantial legal win that could reshape how the [00:01:00] projects qualify for tax credits. So a judge up in, uh, the District of Columbia vacated IRS Notice 2025-42. So if you remember that, uh, from a- about a year or so ago, uh, f- it found that the, that notice was arbitrary and capricious under the Administrative Procedure Act.

The notice, which was issued following a July 2025 executive order, had eliminated the 5% safe harbor for wind projects, uh, a provision developers have relied on since about 2013 to establish construction start dates without breaking ground. The court found the IRS failed to justify removing it, ignored industry comments, which I had read, and I agree with that, and gave no reason for treating wind differently f- than other clean energy technologies.

So That his executive order came down and said, “Hey, we don’t like wind. [00:02:00] IRS, write a rule and make it hard for wind to get installed in the United States.” And so they dutifully did it, but a court is throwing it out. This has some pretty significant implications because if you hadn’t broken ground before this ruling, I think the– what was happening was be- if you hadn’t broken ground by July 4th, your project wouldn’t qualify for some tax credits.

But now, if you have 5% safe harbor, you still are in the game, at least for now. Now, Wanda, that’s gonna make a big difference to asset managers and developers, won’t it?

Yolanda Padron: Yeah, it’s really exciting. I think it opens up the, the playing field for, for some of these projects that might be a little bit behind schedule.

Um, of course, a lot of teams had to change their plans and their pipeline when, um, you know, the big, beautiful bill passed and, I mean, it’s– of course, it adds a little bit of additional volatility, right, to, to wind and, and solar in the US, but it’s exciting to see at least things for, [00:03:00] for those of us that are in the wind and solar side, the, it’s a little, little bit of, of hope there.

Allen Hall: And Matthew, uh, even in terms of opening up o-o-operations and, uh, getting contracts signed, this should make a big difference in sort of opening the floodgates a little bit. Although there is a short timeframe. We’re, we’re recording on, what, what is today? June 10th. So you have, in theory, less than 30 days before the July 4th deadline, but hopefully this stays.

You think there’s a chance this just gets completely, uh, wiped out, the executive order and the IRS notice and- It’s back to what we remember for the, for the last, ooh, 12, 13 years?

Matthew Stead: Uh, yeah. I’m, I’m, I’m hopeful, and I, I agree with Yolanda. I think you, you said it really well. Um, I think this is a, a glimmer of hope in, um, a sometimes gloomy, um, environment.

So I think that’s great. In terms of going back to where it was, um, I mean, I guess my observation has been that, [00:04:00] you know, things in the US were a bit, um, distorted. You know, distorted through the, the PTC, um, and the whole repowering thing after 10 years is quite a distortion. So I think, um, you’re not necessarily going back to the good old days, um, might be the way, what will happen.

Allen Hall: I think there is a lot of people actively trying to dig holes at the moment, and I, I’m sure they’re gonna continue to do that. Yolanda, do you th- you think anybody’s gonna stop and kinda say, “Oh, we have the 5% rule. We’re, we’re good”? Do you think, or you think they’re gonna still go ahead and really start construction and then just keep things continually moving on site?

Yolanda Padron: I don’t think they, they can really stop, right? Because you, you don’t know if, if anything strange happens. A lot of people didn’t think the, a lot of the provisions in the big beautiful bill were gonna, were gonna see the light of day, and they did. Um, but it does, I really hope it brings at least a little bit of breathing room for some people.

I know it’s, it must be… I mean, I have some friends in development, and they’re, they’re q- a little [00:05:00] bit stressed right now just with everything going on. Um, so, so I really hope for them at least they, you know, if, if they’re a little bit behind schedule, then it, it’ll be, it’ll still be fine.

Allen Hall: Delamination and bondline failures in blades are difficult problems to detect early.

These hidden issues can cost you millions in repairs and lost energy production. CIC-NDT are specialists to detect these critical flaws before they become expensive burdens. Their nondestructive test technology penetrates deep into blade materials to find voids and cracks traditional inspections completely miss.

CIC-NDT maps every critical defect, delivers actionable reports, and provides support to get your blades back in service. So visit cicndt.com because catching blade problems early will save you millions[00:06:00]

Norway’s Storting has voted to pause the 35 billion Norwegian krone support program for floating offshore wind at Utsira Nord. The Conservative Party secured a parliamentary majority for the external quality assurance review, a socioeconomic analysis, and a technology development assessment, all before the Storting will authorize any commitments.

Equinor and Vårgrønn, along with EDF and Deepwind Offshore, each hold allocated 500-megawatt areas and were preparing to compete for that subsidy. Equinor says the project will continue for now. I think everybody is saying that at the moment. But, uh, Equinor cannot rule out consequences as framework uncertainty compounds in the already challenging nature of floating offshore wind development.

So Utsira Nord is a massive project. So it’s, it’s about three and a half billion US dollars [00:07:00] to go do this. We had Mads Furuseth and Anders Naslund about a year or so ago, maybe a little bit longer, talking about the project and how big it was and how important it was that Norway did this for floating offshore wind.

But with this, uh, recent change in the parliament of Norway, it does seem like they’re slowly going to try to kill it by putting in a number of, uh, reviews, which is how bureaucracies tend to kill things. Is put it under six, seven, eight reviews, different committees. They all take time to get together.

They have to put out a report. It could be two, three years from now. At that point, the world has completely changed, and everybody’s moved on. Does that seem like the outcome here at the moment?

Matthew Stead: Yes.

Allen Hall: In my mind, there’s really two big areas for floating offshore, which UK, right? That there, there’s some massive projects there, Green Volt being one of them, and then there was Sue & Nord.

So between the two, I feel like the, the UK one was going to [00:08:00] happen. The question whether the world was gonna move towards floating offshore wind was gonna happen up in Norway. If Norway decided to do it and could get it developed, and it has the capability to do it because, because they have that skill set, uh, right there in Norway.

If they could do it in Norway, everybody in the world would learn from it and figure out how to do it. Does this really set back floating offshore wind globally?

Matthew Stead: Yeah. I mean, going back to what I said before, and I, I’ll defer to Rosie on this as well, but, um, when I was at, at Blades Europe, um, one of the, one of my long-term contacts, um, y- was in floating wind, um, and had, um, left the industry.

He basically said i- in his view that the offshore wind industry was slowly, um, in decline or slowly dying. Um, so I’m just wondering if this is just evolution of viability of offshore wind.

Rosemary Barnes: Is offshore wind in decline? I think if you look globally, it’s, it’s not in decline. I, I haven’t looked in, in depth at the figures just based on what, you know, [00:09:00] headlines I’ve seen and podcasts I’ve heard, but I think that globally it’s still on the rise.

It’s just that- It’s only in Europe that things are really moving with speed, right? Like, people were expecting heaps of growth in the US and now no- nobody expects that. Floating offshore wind, it’s… I th- I still think it’s too early to say. There are plenty of countries that don’t have any good energy options besides, um, floating offshore wind, like Japan.

What their energy transition looks like is gonna depend a lot on their culture and what people think, ’cause, like, if you go through, like, the engineering solutions that Japan could have, the ones that make the most sense from an engineering point of view are not popular at all, are not politically viable.

Like, Japan could easily have a subsea cable connecting it with, um, with China, for example, or Korea, but I don’t think anybody, anybody thinks that that will ever happen because, you know, politically it’s, it’s very far from being possible. What else could they have? Geothermal. They’ve got heaps of [00:10:00]geothermal resources, like really good traditional geothermal resources, but my understanding is that it’s super unpopular because their onsen, um, community doesn’t want it.

Uh, my understanding is that they’re worried that if you put geothermal, um, if you exploit geothermal resources, then the onsens will not be hot anymore, and again, my limited research understanding is that it’s not true. It’s different resources. The two aren’t connected in any way. Um, and yeah, there’s actually a community geothermal, um, facility near Fukushima.

I’m trying really hard to get over there, but I’m, I’ve got a roadblock at the moment because, uh, n- no one there speaks English, so I need to find somebody to, to come with me and, you know, I’ll have one, one day to try and get there on the fast train and back to Tokyo in, in a single day. So it’s, it’s a bit of a stretch, but I’m gonna try.

But anyway, so yeah, what have we… We’ve ruled out, like, subsea cables, ruled out geothermal. Floating wind is good.

Allen Hall: Well, speaking of Fukushima, [00:11:00] there’s been a more recent push in Japan to start up some of the nuclear facilities. So after the tsunami, was that 2012, 2014 when that happened? It was a while ago.

Uh, when the tsunami happened and h- had that, uh, nuclear accident, they, they s- shut down all the nuclear facilities in Japan, but it does seem like they’re trying to restart some of them And, and maybe it’s just the demand for energy and, and they’re trying to weigh that off with offshore wind or floating offshore wind.

At what point, you know, which one do you choose? It has to be driven by cost and availability.

Rosemary Barnes: Yeah. And so Fukushima, I just looked it up, it was 2011. Um, and yeah, so I mean, I think it is very fair that they had a reaction to that and they wanted to put the handbrake on nuclear at that time, or they did more than put the handbrake on, they did like a handbrake turn.

Allen Hall: They shut it down.

Rosemary Barnes: So, and it, you know, it’s gradually ramping up. I think that their target for nuclear now is to, to regain, um, 20% of their electricity from [00:12:00] nuclear by 2040, something like that. It was 30% prior to that incident. Um, so that will be part of it, but it’s not, um, it’s not all of it. And then even if you think of, uh, okay, so forget climate change, just, you know, we want, Japan just wants energy and they don’t care about climate change, you know, ’cause that, that, that could be true.

What are their ch- choices for that? They import a whole bunch of… They, they import nearly all their energy. Everything that’s not nuclear basically is, is imported. Um, coal, but a lot of LNG, and, you know, that is not exactly an appealing prospect at the moment either. It’s not secure. Prices are very volatile.

We’ve had, like, two fossil fuel shocks in the last, what, like four years or something like that, and how many more, how many more are we g- are we going to have? You know, like energy security is important, totally separate from climate change issues. So I don’t think we need to rely on Japan, like, you know, [00:13:00] steadfastly staying the course because their, their existing o- opportunities are not, are not great for fossil fuels either.

Allen Hall: I don’t know what country’s gonna stay the course right now, really. Maybe the UK?

Rosemary Barnes: Oh, I think it’s- Countries that have other reasons for going to renewables are the ones that are gonna stay the, stay the course. Um, and there are plenty of examples of countries where it just, it is by far the easiest, cheapest, fastest option to get more electricity.

Um, you know, like all of Africa, for example, is, is facing that as a, uh, a better development path than trying to build big, um, fossil fuel power plants. But even that, you know, like in India, they’re making a huge transition, Pakistan, not to mention Australia, where now batteries are having more of an impact on electricity prices than gas is.

So our electricity prices now finally are dropping, um, this year for the first time because of how many batteries have come on and are now, you [00:14:00]know… Like they’ve just flattened. The evening price peak used to be on average about, like, I think $400 or something dollars a megawatt hour, and now it’s like 100.

In one year we had that, we had that change, yeah, just from the amount of batteries that have come on in the last year or two.

Allen Hall: Why does that make such a big difference in the price of electricity, the battery aspect?

Rosemary Barnes: Because, so the way that Australia… Australia’s electricity market is pretty similar to Texas, so if you understand that, then you can probably understand Australia’s.

But, you know, at any five-minute interval, people, like, they know how much demand there’s going to be, and then people are bidding in how much they would supply electricity for in that five minutes, in real time as well. It’s not like day ahead or anything like that in Australia. The, like, last one they need is what everybody gets paid.

So, like, solar power is gonna bid in at, like, you know, practically zero, um, or maybe negative prices actually if they’ve got power purchase agreements in place. And then, you know, wind a little bit more, and then coal, uh, you know, a, a bit [00:15:00] more than that, and then gas, the open cycle gas turbines, the peakers, they’re very expensive.

They’re bidding in at 400, $400 a megawatt hour. If there’s enough batteries that that gas doesn’t need to bid in, then all of a sudden we don’t have the gas price that everybody has to pay. We have the battery price that everyone has to pay, and that is very, very cheap and will become cheaper as there’s more of them in the, in the system.

So it’s like a threshold event. You, you know, um, even if you’re using only a tiny bit of gas, if you need any gas at all, even like, you know, one megawatt of gas, everybody gets paid the gas price. If you just get a little bit more battery in and you don’t need it anymore, bam, the price just falls. So that’s what we…

We’ve passed that threshold now.

Allen Hall: Isn’t that where the UK is trying to get, is to get past that threshold where renewables are that last addition to the grid and kick off peaker plants and some expensive other- fuel sources. That’s I, I [00:16:00] think where everybody’s gone because they have the same system where the, the last one in is what sets the price for everybody.

Rosemary Barnes: Yeah. The UK’s a little bit different because one, they’re connected to Europe, and two, they’ve got nuclear, so they do have that kind of base load.

Allen Hall: Let’s go down the rabbit hole just for a second. So if the peaker plants don’t come on, that means that the battery electricity supplying the grid is pretty low in price.

It seems like they are losing money on their investment in the battery That they were hoping the price would be higher. Because if the peaker plants are still going on, that would be a $400 price and they’re gonna come in at, like, 350, so that would make sense. It, it helps pay off the battery investment.

But if they’re dropping the price down from 400 to 100, it would seem like the battery investment may not be a, a wise decision.

Rosemary Barnes: For sure they’re making less money, but it was– they were making crazy profits for the first little, the first few, few years of, you know, grid-scale batteries. And even [00:17:00] home batteries, people were making a l- a lot of money off that, and it was crazy.

Like, I’m on some, um, some Reddit subreddits about, uh, you know, people with home batteries and-

Allen Hall: Slash battery?

Rosemary Barnes: Matt probably is too. Matt’s a Beta G enthusiast, so I’m sure that he is just as excited as me. But anyway, so on one of these subreddits, you know, people used to talk about, “Oh, I made 100 bucks last night,” um, or, or whatever, you know, just a household.

And now all the posts are complaining about there’s been no price spikes all year. You know, I thought that I was gonna make heaps of money off my battery, but people are really change- changing how they think of it. And now it’s like… And l- like I want– used to want to do this. I don’t have solar panels yet ’cause we need a new roof, and I’ve been waiting a few years to, one, live in a house that I own, and then two, get a freaking new roof.

Um, and I thought I’m gonna just, like, cover it in solar panels, get a huge battery, and I’m gonna be an energy trader in my free time and make heaps of money, and now that is [00:18:00] not the strategy anymore. The strategy is to just reduce your bills to the m- the minimum that you can. Um, that’s basically, that’s basically it.

So you are right that some of this arbitrage is, um, the opportunity’s over, and that it will be less, um, exciting for, uh, opportunity for people to put more, more batteries in.

Matthew Stead: Just to add to that, through the middle of the day quite often there’s, uh, negative pricing. So if you’ve got a battery, you’re being paid to charge through the middle of the day.

So that actually takes away some of the pain from having a lower, a lower price, um, during the peak.

Rosemary Barnes: But the thing about negative prices is that you need coal power plants for them to be… Like, the only reason we have such pervasive negative prices is not because solar plants have PPAs that are, you know, make it worthwhile for them to generate even when the price is slightly negative.

The real thing is that coal power plants don’t want to turn down below, I don’t know, yeah, like 20, 30% during the middle of the day. They have to be on if they want to make money in the evening, and that means that they bid in at, like, [00:19:00] negative 50, um, so that people– so that they can stay running. And that’s where the bulk of our negative prices come from.

So

As coal power plants close, those negative prices will go away. Um, and when they close, we should get some better evening price spikes again. So, you know, like nothing ever stays the same for long, which is why it is such a fascinating hobby to have, being interested in the electricity market, because it’s never the same from one year to another.

You’ll never understand it, ’cause it’s never, it never stays the same long enough to really get your head around it.

Allen Hall: You need other hobbies. You really do.

Matthew Stead: A friend of mine works in trading, and, uh, he said, “As long as there’s volatility, there will be progress.” So much like what Rosie was saying is the more volatile it is, the more opportunity there is for people to come in, um, and change it.

Allen Hall: I just don’t know how the battery thing plays out once that threshold is reached. When you have more batteries on the system and you knock down the price that [00:20:00] much, I think battery sales, industrial batteries really slow down because they’re all looking for that quick ROI And they’re not gonna get it.

Rosemary Barnes: You have to wait for all of the coal to close before you would find out what’s the right amount of batteries to have in the, in the grid.

Allen Hall: Yeah, yeah, yeah. That, I totally agree there, yeah.

Yolanda Padron: You’d still get, like in extreme weather events and stuff, you’d still get a big price spike, right, for all these batteries.

Allen Hall: Back to Matt’s point, more volatility.

Rosemary Barnes: If you want the market to respond, you need to give enough incentive to invest in assets so you’ll have enough when it’s needed. And because it’s really infrequent, then it has to be a super high price to, um, bring on enough investment. And will this system… The system has worked absolutely, you know, pretty well in Aus- Australia at least.

Will it continue into the future with more variable prices and renewables? I, I don’t know, and the government is starting to do some things like, uh, you know, like a lot of [00:21:00] electricity markets have, um, not just energy markets but also capacity markets where you will pay a battery or a gas plant something to be on standby basically, um, so that if there is, um, if there’s a shortfall then they, then they have to respond.

So in Western Australia they have that, but across the east of Australia th- they currently do not, do not have that. It’s energy only.

Allen Hall: Really? How do you not have capacity payments?

Rosemary Barnes: The majority of their profits are made in just a few hours a year when there are those price spikes, so that’s, that’s h- part of their business case.

Allen Hall: I mean, there, there is arbitrage happening on the electricity grid. That’s not the best place to be arbitraging things because you will have players that won’t provide electricity just to drive up the price.

Rosemary Barnes: Uh, and it happens in Australia too, but, um, you know, because batteries are such a distributed resource, it, it will become harder and harder to do that when, you know, the, um, the ownership of these batteries is, you know, households as well as, um, yeah, as well as [00:22:00] big companies.

Matthew Stead: So offshore wind, I was talking to an OEM a, a little while ago and, uh, talking about blade repairs for offshore wind, you know, floating, floating wind. Um, so specifically floating wind. The OEM was extremely concerned about floating wind, um, because it makes it very, very, very hard to change blades. So the story was that if you’ve got an offshore floating platform, you’re basically gonna have to tow the wind turbine back to port to change a, a blade.

Rosemary Barnes: They see that as a, as a pro, not a con though. Yeah. That, that’s because it’s very hard to… Like, it’s not only floating offshore wind where it’s very hard to remove a, a blade out at sea, like fixed bottom offshore wind, that’s incredibly expensive to remove a blade. So floating is like, well, you can just tow it back to shore and then you can do it all in the port.

I, I, you’re looking skeptical, Matt, and I’m also skeptical about how it actually plays out. I know that, um, what was it? The, [00:23:00] the one- An EOL project off the coast of Scotland. I can’t remember what it’s called now. Like what, the first big one, the big wind farm, a floating offshore wind farm

Allen Hall: HiWind Scotland

Rosemary Barnes: They had a, a problem.

I don’t know if it was a serial issue or also, like it’s the first big wind farm, and there might have been like some operating condition they weren’t aware of that caused some problems. They had to tow back everything to port, and they stayed there for months and months. So like maybe, maybe close to a year or over a year, I’m not sure.

It was a really long time. And so, um, yeah. But then, you know, like what’s the alternative? If that had happened out at sea, it would’ve been more expensive. If, it still would’ve been shut down, not doing anything, and you would’ve had like helicopters out there every single day bringing teams and, um, you know, huge vessels with cranes and yeah.

So like it’s, maintenance at sea is never good.

Allen Hall: But the whole point of the HiWind project was to get some of these problems figured out, and one of them was just towing it back to port and [00:24:00] doing major repairs or component exchanges make sense. I think it’s a, it’s a lesson well learned, and we’ve moved on.

I guess the question is, does offshore, floating offshore in particular, have much of a future if Norway’s not willing to do it?

Matthew Stead: I think it’s a good comparison with, um, data centers in space.

Rosemary Barnes: You know where else they’re planning to put data centers? Not just space and offshore, also like, um, underwater ones, like on the deep ocean floor, um, on the moon somewhat.

Like there’s an actual company that is apparently developing a, a data center on the moon

Allen Hall: As wind energy professionals, staying informed is crucial, and let’s face it, difficult. That’s why the Uptime podcast recommends PES Wind magazine. PES Wind offers a diverse range of in-depth articles and expert insights that dive into the most pressing issues facing our energy future.

Whether you’re an industry veteran or new to wind, PES Wind has the high-quality content you need. Don’t [00:25:00] miss out. Visit peswind.com today. Well, in this quarter’s PES Wind magazine, there are a number of great articles, and if you haven’t downloaded your copy, you should do that at peswind.com. There’s a good article from Global Blade Services USA, and it’s talking about the technician problem and how it’s not gonna, it solve itself, obviously.

But Global Blade Service is putting some numbers to it. And Rosemary, this is really directed at you. Blades represent roughly 20% of the total, total turbine capital cost and are the leading driver of unplanned downtime.

Rosemary Barnes: Yeah, 40% of O&M.

Allen Hall: Right, and 75% of all blade repairs are already handled outside OEM warranty.

That number seems really high, but maybe after the warranty expires?

Rosemary Barnes: Do you say 30% of, of repairs are repaired under warranty? That’s, uh, unexpectedly high from my point of view. [00:26:00] But, you know, how would I know? No one’s getting in touch with me if, you know, they’ve got a problem with their blades and it just got fixed under warranty.

Then they’re not paying a consultant to come sort it out. I only, I’m, I’m only there when the warranty is nearly up or it’s already over.

Allen Hall: So they, they’re saying that the, the ratio’s even gonna grow more towards out of warranty repairs. But the problem is having technicians. And the deeper problem is developing all those technicians in time as that need grows.

Uh, reaching full structural repair competency takes a rope access technician eight to 10 years. A basket technician is five to seven, and a factory technician is four to five years, meaning the workforce, uh, the industry needs for the next decade has to start training now. I, I think we’re seeing this in full force.

I- the issue is keeping good people in the industry as it fluctuates up and [00:27:00] down all the time and is very seasonal. Because there are really good rope technicians out there who know what they are doing, and it does take a, a minimum of three years to be competent. And then to be that lead person, it takes four or five solid.

And to be, uh, the, the relied-upon person, especially for some of the more complicated repairs, it’s gonna be six, seven, eight years before you’re there. It’s just an exposure thing. Are we in a technician crisis?

Rosemary Barnes: Crisis is maybe a little bit inflammatory, but, uh, we’re in a technician challenge

Matthew Stead: But it’s a pretty, it’s a pretty basic topic, Allen, isn’t it?

Like, um, you know, there’s more and more wind turbines, there have to be more and more technicians. It takes time to train. So, you know, it’s, it’s just, it’s pretty much basic maths and, um, you know, it’s like te- you know, tradies to build houses. Um, you know, unless you’ve got the tradies, you can’t build houses in a cheap way.

Yolanda Padron: Part of the issue is that, you know, say there’s [00:28:00] 10 technicians that are available in the area, right? Then you … maybe they work under two different companies, and then one company goes bankrupt, so then they all work with the same company. Another company pops up, or someone gets kicked off site from the OEM side, and then a month later they’re back with the third party.

And then it’s just really difficult to keep track of kind of who’s still there and who’s not, because some people have the certifications and maybe they’re not really, really great at what they do, or other people have a lot of training and a lot of experience, and it’s just difficult to track exactly, you know, where they are now.

I know that the, the strategy here oftentimes is you’ll find one person that you like and you kind of follow him around, or follow them around whatever company they’re, they’re with at the moment, and then just use that company.

Matthew Stead: The other point I was going to make is that there’s also the seasonality, isn’t there?

So you know, if you’ve got a great, a great technician, when it’s cold, they can’t earn cash from [00:29:00] repairing blades.

Rosemary Barnes: Aren’t they hired as, like, seasonal workers in America and they just don’t get paid for part of the year? That’s not how it’s done here. I mean, I guess we don’t have the climate where you have to, like, totally shut down, so they’re not, like, sitting around getting paid for nothing.

But, like, that’s a really unim- unappealing feature of the of the, um, field, isn’t it? If you’re deciding what you wanna, what kinda job you wanna do, you want one where you can get paid for 12 months out of the year, not just, I don’t know, like eight or whatever it is.

Matthew Stead: I know there’s been a lot of discussion between, like, Australian US repair companies of, like, shipping technicians down here during the Northern Hemisphere winter and vice versa, and it gives, you know, chance of exploring the world.

But, you know, if you’ve got kids and family, you’re not gonna necessarily wanna do that either.

Rosemary Barnes: It’s such a tiring job, though. I don’t… Like, there’s, um, I think it’s fine if people do it for, like, a hard 10 years and then, um, yeah, move on to… Because you obviously learn a lot as a technician, so y- you know, like, there’s a lot of office jobs that you would be really good at [00:30:00] because you had that physical experience.

But yeah, like, I, I do think that there’s heaps of young people that are traveling the world being wind turbine technicians.

Yolanda Padron: At least in Texas, I know a lot of rural areas where they don’t necessarily have a lot of opportunities to get higher education, and so going to be a technician is a good route for them to then go into a larger part of the industry, um, to, to kinda get a head start there.

Um, and they get a lot of really valuable skills, and oftentimes, like you said, Rosie, they’ll, they’ll get picked up by, um, by the owners or the OEMs or someone, um, because of their experience there. But it, but it is quite a bit of, of hard work and, and physical, physical labor. I climbed one tower and I was sore for two weeks, so really, really not my cup of tea.

Rosemary Barnes: I’m always, like, so excited to, to be climbing towers ’cause I only do it, like, you know, sometimes no times in a year, sometimes twice a year. Um, yeah, so, like, I’m really excited to go climb, and it’s really cool the first day, and then the second day it’s like, “Oh, this harness is [00:31:00] so heavy. Am I really putting this on again?

Oh my God.” Yeah, so it’s, uh, it’s ob- obviously you get used to it if you, um, if you do climb a lot. The last, uh, last site that I was at, a lot of the technicians were just climbing the ladders so that they wouldn’t have to, you know, go to the gym afterwards. So there’s a lift there, but they use the ladder because then they get their cardio for the day.

So, you know, they’ve obviously got some surplus energy.

Allen Hall: I think it is kind of a myth outside the US, uh, uh, seasonal workers, uh, at least in Europe, I haven’t seen a lot of seasonal workers. It doesn’t mean they don’t exist, of course. But in the United States, there’s a lot of seasonal workers from construction and all kinds of other industries.

People figure it out And it, it’s a lot more common than I think y- being an engineer you think it is, but there are a lot of seasonal workers. So being a, a wind technician is not a bad job.

Rosemary Barnes: I guess they’re just getting [00:32:00] paid extra for the time that they’re working and they just know they’re used to budgeting to cover the few months off.

Allen Hall: They have a winter job. They’ll, they have employment. They already have it lined up where when it gets cold outside, they have someplace else to go. Back into construction for a few months. They’re maybe driving a truck or doing other things that, that bring in income. They have it pretty well figured out.

When– At least the technicians I’ve talked to seem to have a, a plan about it, and they’re not sitting by the television for six months. That’s not what’s happening. It, that there’s a lot of employment opportunities here in the States, and so they, they’re pretty nimble.

Why Is Trump Still Here?

Published

on

I challenge anyone to watch this short video and explain how Trump still has enough standing with the American people to remain president.

This is just so embarrassing.

Rich Americans aren’t happy that their country is a laughingstock around the world, but their fortunes are multiplying, so what’s the big deal?  How does personal integrity come into play when there is so much money at stake?

The MAGA crowd, i.e., uneducated white people, believe Trump when he says that he has brought back respect for the United States.

Why Is Trump Still Here?
