If the thought of implementing clean energy in your home is daunting, you are not alone. For many of us, even small steps like small-scale energy efficiency upgrades, and especially larger ones like installing rooftop solar panels, seem like unattainable goals, especially when the costs for each upgrade keep racking up.
It is important to remember that not every upgrade has to be done at once, and that there are resources and funding available to help make energy upgrades more affordable. As part of the Clean Energy Generation, you can choose to make home energy upgrades to benefit you and your family’s health, save money on energy bills, and play a part in making your community safer and cleaner, no matter your age, income, zip code, or abilities.
Larry Heiman from Dunwoody, Georgia, is one member of the Clean Energy Generation who is tackling energy inefficiencies and carbon pollution in his home by making home energy upgrades – and he had a little help. Larry has taken advantage of tax credits and rebates from the Inflation Reduction Act (IRA) and his local utility company almost every step of the way as he has made his clean energy transition. This financial support made his choice to take the leap to tackle inefficiencies less daunting. Throughout this process, Larry has learned a lot about clean energy and about how to take advantage of available resources, and now he is spreading the word to his community.
Tune into our next Clean Energy Generation webinar on Friday, March 1 from 12:30 PM – 1:30 PM ET to hear more from Larry and SACE staff about how each of us can play a role in the Clean Energy Generation by making home energy upgrades, and read on to learn about Larry’s path to using clean energy in his home, the financial incentives his family used along the way, and how he’s sharing what he’s learned to help others.
Register for the Webinar on March 1
What was the first way you took advantage of tax credits and rebates from both the IRA and your local utility?
I’ve always been interested in and worried about climate change, but as far as my own personal life, I didn’t take any action until last year. I had learned about and followed the Inflation Reduction Act (IRA) and thought a lot of it could be applied widely, so I figured why not dive in and do something myself. That’s how it started, and I chose to start with my car. The first thing we did was buy an EV last April with the help of a $7,500 rebate.
Shortly after, we installed a level two EV charger, which we did not get any tax credit for from the IRA because we are not in an eligible census tract. Much of Georgia and the Southeast in general does fall into eligible tracts, like lower-income or rural, and can receive a 30% tax credit on EV charger installation costs. In the end, we did get a rebate from Georgia Power, so it’s good to check with your utility for those.

Our EV is our workhorse car – we use it to take our daughter to school and drive to work, and we try to use it any time we drive around town. Very recently, we were able to trade in my old car for a plug-in hybrid EV, but before that, we had the one EV. It doesn’t have to be all or nothing – or all new off the lot. Now, many people can get up to a $4,000 tax credit on certain pre-owned EVs at the dealer.
What energy efficiency measures have you taken around your house, and how did you get started with those?
After buying our EV, we installed solar panels in July 2023, but in retrospect, I would not recommend installing solar first to electrify your home. The energy efficiency work instead should be the baseline – it’s like putting a bandaid over paper cuts all over your house.
We bought our house in Dunwoody, Georgia 10 years ago. It’s 53 years old and your average two-story home, built in an era where people didn’t care or know too much about energy efficiency. To learn how to make the house more energy efficient, I’ve had two energy audits: first through my utility with a rebate, and second through a local HVAC contractor. The second audit was the most useful. I got a detailed report from tests they conducted around my house, such as a blower door test. They pointed out places around my home that could be sealed better, from most important to least important.
For example, we have a basement that has heating and cooling, where it’s not as important for us to air seal between that space and the first floor because the exchange of air is about the same temperature. But in our unconditioned attic, they checked how the insulation is holding up and where air sealing is needed, and they showed me that there are many places where air passes in and out of our attic, like around recessed lighting receptacles, the door to the attic, and holes where wires pass through. So they recommended caulking each air leak on a hole-by-hole basis and adding better insulation, or spray foaming the attic, which is insulation and an air sealing solution all at once.
So this year, we plan to do the attic air sealing and insulation improvements to save on energy bills immediately, and to prepare our home for installing a heat pump in the near future, so that our home can be heated and cooled more efficiently. To offset some of the cost of the air sealing and insulation, we plan to use both tax credits from the IRA (25C tax credit of up to $1,200 per year) as well as rebates from Georgia Power. When we one day replace our existing HVAC system with a heat pump, we can also receive a tax credit on that of up to $2,000.
So far, we’ve done little things ourselves, like door weather stripping and baseboard caulking. If you want to do some work yourself, you can buy the weatherization materials and save the receipts for an IRA tax credit – it adds up, and there are all sorts of home weatherization materials out there to get started.

How have you used tax credits and rebates to install solar panels on your home?
To get started with solar installation, I went to a kickoff event for a local solar installer in May 2023 and had someone come do a consultation, then the panels were installed in July. Thanks to the 25D tax credit in the Inflation Reduction Act, we will receive a 30% tax credit from the IRA on the total cost of the project.
My utility, Georgia Power, does not offer net metering to new rooftop solar owners. Instead, Georgia Power credits us less than half of the retail electricity rate for electricity we export back to the grid – or, the excess of power our solar panels produce but that our house does not consume at that time.
Therefore, it is economically advantageous for us to use the electricity our solar panels generate right when the panels produce it, instead of letting that electricity flow back to the grid. For this reason, we make sure to plug in one of our EVs whenever one of us is home during the day, using the “slow” charger to lengthen the time of the charging session to last the whole day. We also do laundry or other electricity-consuming activities during the day when our panels are producing electricity, rather than at night.
In the future, we may consider installing a battery storage system to complement our solar panels. There is also a 30% federal tax credit for residential battery storage systems provided in the IRA. With a battery storage system, we could store the electricity our solar panels produce, and then use that electricity to power our home during power outages and/or to power our home at night, instead of paying for electricity from the grid.
How are you involved in your community to encourage others around you to take clean energy action?
A goal of mine is to create a group of like-minded citizens to collaborate to promote decarbonization in the community at large, among residents and businesses. The group could hopefully provide education on ways to decarbonize and save money, maybe even offering in-home advice to homeowners and renters. This group would not be limited to Dunwoody, but I felt that it would be best to start by targeting people in my general area. This is what prompted me to get in contact with people who have also signed up with the Clean Energy Generation in my area.
Since last May, I have been on the Dunwoody Sustainability Committee. There are a number of items in the City’s Sustainability Plan, enacted in 2021, that relate to energy efficiency and clean energy that I will be working to get action taken on.
The first action I’ve taken is calculating a greenhouse gas inventory for my local government’s operations, like city buildings and the police vehicle fleet – I teamed up with a professor and his students to work on this in 2023. The results of this greenhouse gas inventory provide a starting point to measure the effects of actions the City takes to reduce greenhouse gas emissions. We just received the outcome of the inventory, and my first action is going to be meeting one-on-one with members of the City Council and the mayor to implore them to demand action from City administration.

Why do you think it is important to implement clean energy in our homes and communities?
For me, the most important reason was first the environmental concern, specifically global warming, but saving money and keeping my family healthy are big benefits for sure. I am trying to encourage others to do what they can to decarbonize, so it would be a bit hypocritical not to first do what I can myself with my own personal infrastructure. Plus, going through this personally will give me a chance to learn about the processes so I can then pass on tips to others, hopefully.
GET INVOLVED IN THE CLEAN ENERGY GENERATION
As members of the Clean Energy Generation, we all have the power to take action and make a difference where we can in reducing our environmental impact. Like Larry, we can explore energy upgrades to make our homes more energy efficient and comfortable, as well as the methods to help make these changes more affordable – and then we can share what we learn with our communities.
You don’t have to be a clean energy expert to make an impact – just ready to learn and excited to make a difference.
Remember to tune into our next Clean Energy Generation webinar on Friday, March 1 from 12:30 PM – 1:30 PM ET, where Larry and SACE staff will talk about the ways each of us can play a role in the movement through making home energy improvements, plus the funding that is available to help make them more affordable. There will be plenty of time for questions and answers. We hope to see you there!

What Operators Want to Hear at WOMA 2027
Two days of operator meetings in Melbourne shape the WOMA 2027 agenda, from performance upgrades and cable faults to foundations and bolts.
The Uptime Wind Energy Podcast is brought to you by Weather Guard Lightning Tech, creators of the StrikeTape Ultra LPS retrofit. Subscribe to Uptime’s Substack newsletter. And check out Rosemary’s “Engineering with Rosie” Youtube channel. Have a question we can answer on the show? Email us!
Allen Hall: Welcome to the Uptime Wind Energy podcast. I’m your host, Allen Hall. I’m here with Matthew Stead and Rosemary Barnes. And Rosemary, where are we?
Rosemary Barnes: We’re in Melbourne, and we have been visiting future attendees and sponsors and people interested in, in the event to see what topics that we should be talking about.
What are the hot topics of the moment?
Allen Hall: Which is a very interesting two days, Matthew, in that, uh, we h- did meet with a number of operators based in Australia, but, uh, they’re also very worldly. They have talked to companies all over about operations and, and maintenance, and there are some really eye-opening topics- Mm
that will be- Mm … at WOMA 2027 this year.
Matthew Stead: Yeah. The thing that was interesting for me was [00:01:00]that actually the topics have changed each year. So, um, they’re evolving and the industry’s continuing to, to do better, and so that, that was really interesting. Performance upgrades was probably one of the big areas of, of new interest, I think.
I think we heard with the pressure on pricing, uh, the market and so forth, you know, that, that 1% or 2% now is becoming more important. Um, so I think, uh, upgrades will definitely feature quite a lot. Um, balance of plant was also a big topic. Um, you just can’t ig- ignore the, um, transmission, you can’t ignore the transformers, you can’t ignore, uh, condensers and all these sorts of things, so yeah.
Rosemary Barnes: Cables.
Matthew Stead: Cables.
Rosemary Barnes: Terminations. Terminations of cables. Specifically raised several times.
Allen Hall: Yep. Yeah. It’s all about being more efficient, uh, getting more production, and then with the PPA prices, uh, that are changing-
Matthew Stead: Mm …
Allen Hall: rapidly, uh, everybody is paying more attention to the bottom line.
Matthew Stead: Mm, mm.
Allen Hall: Absolutely. There, there’s less cash running around, uh, chasing new development.
It’s [00:02:00] more of a focus on making sure your, at least your existing assets are performing as, as well as they can be- Mm … which then opens up the, uh, Pandora’s box of opportunity. Mm. Because there are 1%’s all around a wind turbine. More specifically, uh, all the drive train issues, the blade issues, the generator issues, and even going into the substation.
Mm. I, I was really shocked on BOP e- the, the one topic that came up, uh, yesterday and today was buried cables. Mm. Like-
Matthew Stead: Faults …
Allen Hall: faults.
Rosemary Barnes: Yeah. Junctions. Finding- Yeah … finding faults and what to do about them. Yeah. Yeah. But I think in addition to just wanting more revenue, I think people have, are getting more sophisticated about what actually matters and then the finances.
You know, everyone’s focused so much on availability, and now people- Mm … are like, okay, yeah, like once you’re at a certain level of availability, gets harder and harder to get more. And actually, you know, not all availability is equal. Is good. It, it [00:03:00] depends. Yeah. Yeah, like you wanna, um, you wanna focus on how much you’re generating at the times when electricity prices are high specifically, which usually means during lower wind speed periods.
Yeah. Which is actually good because that matches really well with what is actually possible. It’s, it’s hard to get more power out of the turbine if it’s at, you know, its rated power, then you’re not g- More efficiency is not gonna get you any more, um, power output, whereas lower in the power curve- Mm … um, when wind speeds are lower, there’s less electricity in the grid and so prices are higher.
And so- Mm … yeah, I mean, that’s, that’s why people are really asking to know more about what efficiency upgrades are possible, better ways to operate, scheduled maintenance, um, all those sorts of things. Mm. So that will be really interesting.
Matthew Stead: Raising the bar on sophistication. Um, but also life extension
Allen Hall: Yes, a lot of discussion about life extension
Rosemary Barnes: Yeah, end of life and life extension End of life Yeah, um-
Matthew Stead: Foundations, structures Which is
Allen Hall: tied to PPA.
Mm. A lot of that [00:04:00] discussion I, at least I looked at it as, uh, if I had a PPA and I can continue with that PPA with an existing turbine, I want to do that. Mm,
Matthew Stead: mm,
Allen Hall: mm. But how do I do that and how do I know that that existing turbine can last another five years? It seemed to go in five-year blocks, like can we get to another five years and then another and then, then another.
Wow.
Rosemary Barnes: Yeah. Once you get to 20, 20, 25 years, I think people like, uh, they, you know- It’s getting a little- Their original agreement might have been for 20, then they kind of just assume that there will be another five, and then after that they’re- Yeah … kind of reassessing cyclically and yeah, I know that people make plans for, you know, what components are replaceable, what would they have to get in, and I think that sometimes, uh, people doing those plans aren’t as familiar with the, you know, actual technical issues that are being faced.
Like, is a blade a replaceable component? It may be early on in the life it sort of is, not easily, but you know, like a 25-year-old wind turbine, you know, good luck trying to order 10 new blades because you’ve got a, you know, an issue that’s-
Allen Hall: Oh, well you, you need to read the news. Did you [00:05:00] see the news today about, uh, the, the wooden wind turbine blades as a replacement for aged blades?
That, that’s happening- … in real time, Rosa.
Rosemary Barnes: Okay. I know they- Yeah. Yep, yep. Okay. Okay. So that, that’s, that’s good. Making carbon new blade. E- even so, I don’t think that they’re- Okay. … gonna be, like, super-duper cheap, so you’re still gonna wanna be, um, doing a trade-off between y- you know, like, what kind of repairs.
You might be able to change the way you’re operating to reduce loads. Um, you might be able to monitor to make sure that your blades are safe. You know, if you know that there’s an issue, um, you just wanna get some advanced warning before blades start falling off your, your tower. Mm. You know, and then you can push it further.
Yeah. Whereas if you’ve got no information, then you have to be conservative and shut it down. Yeah. So yeah, I think there’s a whole lot that can be g- can be done there in that area.
Matthew Stead: There was a point that came up today, which I think was close to your heart, on, you know, if you’re going to be going for 1% or 2% or 0.5% AEP improvement, how do you actually measure that and how do you set up a proper experiment?
So-
Rosemary Barnes: Yeah …
Matthew Stead: I, I, I love that topic. [00:06:00]
Rosemary Barnes: Yeah. No, it’s one that I, um, yeah, I deal with m- my clients I, I’m often… It’s one of the things that Pablo really loves to do, is to organize trials of that nature of new technologies and see if they work. But, um, yeah, asset managers are usually very, uh, focused on fast results.
You know, they’ve got a, a big problem and they want a solution now, so they wanna just roll out the new technology over an entire wind farm. But if you do that, then it’s almost impossible. Unless you get, like, a huge benefit, like, uh, 10% gains or, you know, like reduce your failures by 50% or more, it’s really hard to actually- Mm
pick that out if you just replace everything. Mm. Whereas if you do a really, really good, um, trial plan- Systematic. Yeah … and you match pairs very well so that you have, you know, a control for each turbine and there’s- so many variables in a wind farm. It’s not, it’s not as easy as just, like, randomly choosing 50% to do and not do.
Mm. Mm. Mm. Like, you have to, you know, put some work into the trial design, and then, you know, like, do your statistical calculations ahead of time to know how long it’s gonna take you to get s- statistical [00:07:00]significance. So then you don’t just have a gut feeling about- Yep … how something went. You’ve actually got numbers, and then you can take those numbers to, you know, other wind farms that you’ve got- Yeah
and, and know what’s going on much better.
Matthew Stead: Worst study is an inconclusive study.
Rosemary Barnes: Yeah. Yeah, that’s true. Definitely.
Allen Hall: Well, that comes back to the data analysis- Mm … which a lot of operators mentioned, and how much data there is and what to do with it, and it did seem like a couple of operators have chosen some AI tools, varying degrees, all the way down from Microsoft Copilot to something much more complicated.
Uh, but I think there’s, uh, getting that d- to the last 1, 2, 3%, you’re going to need those tools- Absolutely … because what do you choose? Do you choose a blade? Do you choose a gearbox? Do you choose a generator? Do you go to the substation to get that percentage point or two Without having some really powerful tools- Mm.
you may be wasting your time [00:08:00] and money.
Matthew Stead: Mm.
Allen Hall: Which is a, a, a very interesting, uh, aspect to wind energy because it’s such an industrial business that, uh, we haven’t used heavy computational tools, uh, un- until really now.
Matthew Stead: Mm.
Allen Hall: And maybe Australia’s at the forefront because of the PPA and negative pricing is that that will, uh, actually lead an industry.
Because I haven’t seen a lot of that being used globally. Mm. So this is the first time an operator- Mm … that I’ve talked to has said, “We’re using it.”
Matthew Stead: Yeah. It’s quite a different discussion, um, I think, you know, this year compared to previous years in that I think in the past it was getting to know what’s possible, but now it’s like real case studies are coming through.
And a few of the people had some really good examples that we can talk about at the conference as to how they’ve actually been helped and how they did this and what the outcome was. I think, yeah, that would be really great content on that.
Rosemary Barnes: Yeah. I think it’s gonna be a good mix of people who have used third party tools and have experience with it, people that are doing it in-house and can share- Mm
some of the kinds of results- Mm … that, that you can get just from analyzing your own- Mm … [00:09:00] SCADA data. Um, people talking about how they get the data that they want. Mm. ‘Cause it’s not always so easy. You would think that, you know, you own a wind turbine, you have a right to have all of the data that comes through it, but it’s not.
Um, even if you do technically have a right, it’s, uh, it, it’s harder to actually get it than you might think. Mm. So yeah, sharing all, all those kinds of things. But I think also, like just as important as talking about the successes is talking about the, the gaps that– people still feel lots of gaps. Like, okay, we’ve got all the data, we’re collecting it.
We know that there’s so much potential here- Mm … but we don’t really- Mm … know what we can do, or it’s hard for us to, you know- Mm … make headway in this particular pain point. And that is really useful for companies that are developing tools to know what are the, the problems. Mm. Because then they can e- you know, they’re well placed to fix them.
Allen Hall: Mm. Which leads to the discussion we had with the operators and, uh, some of the suppliers for WOMA 2027. There’s a lot of interest. And as we’re sitting in the conference rooms, I’m thinking, we may not have enough room to [00:10:00] seat everybody. Uh, the WOMA 2027 website is up and running, and you can register now.
So just go to woma2027.com and get started there. At the same point, we’ve had a lot of contact with, uh, pretty much everybody that wants to sponsor the event, and there’s only a limited number of ways to sponsor. So if you’re interested in doing that, you, you need to go to woma2027.com and look at those, uh, part- particular packages and see what- Mm
fits your, your business. Uh- Going back to some of the, the comments we were just discussing downstairs about what we heard at 2026, like, which is only a couple of months ago, right? It’s back in February this year. Uh, there’s, they’re still discussing what happened at WOMA 2026- Mm. Which was very fascinating- Mm
because I think Rosemary, you and I have been to conferences that I have not thought an iota … about what happened at those conferences. Just nothing interesting does occur. There’s no new, new information, there’s [00:11:00] no new science, there’s no new operator approaches.
Rosemary Barnes: Mm.
Allen Hall: But we’re gonna see a number of those- Yeah.
Mm … come next March.
Rosemary Barnes: Yeah. Well, I think it’s partly because I don’t know what other conference organizers do, but, you know, we’ve had a exhausting few days here. You’ve come all the way from America, obviously, and, and Claire as well, also come over, our producer. Um, so, y- you know, like, we’re working really hard to make sure that the topics…
Like, it’s not an accident that the topics are ones that people are talking about later, because we come here to make sure that we get the right topics. And it’s not just these meetings as well. People get in touch, and- Mm … anybody watching, listening, who has, you know, something that they wanna talk about, then definitely, you know, send us a message, and yeah, we’re working on the agenda.
We’ll, we’ll have a draft agenda in the next couple of weeks based on what we’ve learned here, but then we’ve got the hard job of it’s not just that you have a really interesting topic, you need to have a really great speaker- Yeah … or several really great speakers, usually covering several different aspects of the problem.
You know, maybe it’s, uh, yeah, an asset [00:12:00] owner, an OEM, and some, some technology provider, you know, all together giving different, um, yeah, perspectives. That’s, I think, what makes a really great session. Mm. So yeah, we need the ideas for the sessions, and we also need the ideas for great speakers.
Matthew Stead: Yeah.
Rosemary Barnes: Right.
Matthew Stead: Yeah. I think we’ve, we’ve already matched a few of those dots, so- Yeah … I, we’ve heard people asking for certain topics they wanna hear about, and then we’ve heard other operators saying, “Well, this is what we could talk about.” So I think we’ve already-
Rosemary Barnes: Yeah, yeah … got some great
Matthew Stead: progress.
Rosemary Barnes: It was, it was interesting ’cause we, we built up a list of, you know-
Matthew Stead: Yeah
Rosemary Barnes: frequently raised topics, and then you’d say it to the next person that you went to- Mm … and they’re like, “Oh, that’s not a problem for us because we’ve done X, Y, Z.” And you’re like, “Okay. Well, excellent. You can, you can present the solutions that we know that other people- Yeah. Yes … are, are looking for.” Yeah.
So it has been… Yeah. Yeah. I mean, it’s definitely worthwhile coming, as, as tiring as it is. Yeah. Um, definitely worthwhile, and we’ll get a much better agenda for the- Yeah … for the effort.
Matthew Stead: And I think, I mean, it has been tiring. Um, but what, what made it for me was one of the operators said that [00:13:00] this is the only conference they will go to So I think, I think we’re doing the right thing.
Rosemary Barnes: Yeah. Yeah. I, I think so. I understand too, like, you know, all of us, we kind of are forced to go to events because that’s where our, our clients and customers are, and so you need to see them. And yeah, like I’ve even gone to the extent of some events where I don’t particularly like the event, but I know everyone’s going.
Mm. I just go and sit near the event for a couple of days and meet people at a cafe. So yeah, like we can’t get away from it. But if you’re an asset manager or, um, yeah, somebody in that kind of type of work, like you’ve got better things to do than listen to sales pitches aggressively thrown at you that aren’t relevant- Yeah
to what you’re doing. So, um, yeah. Like I, I definitely love to hear that kind of feedback- Yeah … and wanna make sure that we get it every, every year. Like that’s- It’s, it’s
Matthew Stead: encouraging.
Rosemary Barnes: Yeah … yeah, that’s, that’s the point of the conference, so.
Matthew Stead: Yeah.
Rosemary Barnes: Yeah.
Matthew Stead: The other big topic was we would really love more OEM involvement.
Um-
Rosemary Barnes: Yeah. Everybody wants more- … a lot of the operators- … OEM involvement- Yeah … all of the asset owners.
Matthew Stead: Yeah.
Rosemary Barnes: Like we want to [00:14:00] hear from OEMs more, have them there. Um, so yeah, we’re, we’ll be trying to To get those sorted
Allen Hall: Well, WOMA is a global conference, although it’s Australia-based and there’s a, a number of Australian operators.
There are Danish, Americans, uh, plenty of Europeans. Uh, we’re gonna see some from Southeast Asia, I think, this year. Mm-hmm. And, and Japan hopefully will come. Uh, because it’s a, it’s a global conference, there’s global knowledge- Mm … and wind is such a big industry. You may not have the solution in the United States, it may be sitting in Australia, and we need to exchange those ideas.
Mm. And that, that’s the point. So w- we are continuing to look for those world experts as we have received all the inputs of these are all the topics we wanna go hear about. Great. Now it’s on us three to go find some of those world experts and, and try to get them to Melbourne. Yeah. And I, I think that’s a great opportunity.
So if we do call you and ask you to participate in WOMA [00:15:00] 2027, please take it seriously because- Mm … you will be bombarded with great questions- Mm … and contacts and information. Uh, it’s an event you won’t wanna miss. Yeah. And- But I would- … there’s opportunity there.
Rosemary Barnes: Yeah. I’d say we’re, we’re prioritizing OEMs, um, to, to get more participation, ideally to speak, but at least to be there.
And we have heard from multiple asset owners in Australia that they want, they, they want to know what are some of the upgrades that they can do- Yeah … that you’re offering. They wanna know what’s coming next in terms of technology. They wanna know what are some of the non-Western options. So, you know, like it would be great to get some Chinese wind turbine, um, manufacturers as well.
Like, they want all this information. They don’t want a slick sales brochure pitch that doesn’t give them any technical information. So we’re hopeful that we’ll be able to get, you know, some technical people to speak on, yeah, what are the upgrades you offer and how does it work- Mm-hmm … and show us a case study that demonstrates the improvements.
Um, ’cause that [00:16:00] sometimes is really hard to get out of- Mm … out of OEMs. You know, that, “We’ve got this thing, it’s so amazing, you should get it.” Okay, well, what’s the business case for it? “Oh, well, we don’t have any numbers. Just trust us.”
Matthew Stead: Yeah.
Rosemary Barnes: Um, it’s so common to get a pitch like that. So yeah, any, any OEM that has any- anything like that, either for the next generation of wind turbines or for upgrading the current fleet, yeah, if you’re willing to bring the data, then people, they are desperate to hear this information.
Allen Hall: Mm.
Matthew Stead: Yeah. That came up so many times.
Rosemary Barnes: Mm.
Allen Hall: So what were the other, uh, topics that we’re… I’m just not thinking off the top of my head. I know foundations came up quite a bit- Foundations, yeah … which was an odd one, I think, because we haven’t seen that a lot in Australia. Yeah. But this year, foundations, foundations, foundations.
Basically, the health of foundations. Yeah.
Matthew Stead: Yeah. I think really there was a lifting of the maturity. Um, I think the topics were sort of showing that, you know, Maslow’s hierarchy and moving into the more of optimization rather than making do, and I think life extension around the foundations was a, a really good example of that.
Allen Hall: And bolts.
Matthew Stead: Bolts? Yeah, bolts.
Allen Hall: [00:17:00] Everybody said bolts. Bolts.
Matthew Stead: Bolts.
Allen Hall: You think the world’s simplest device, we’ve been making bolts for nearly 1,000 years or at least a couple hundred. But it does- And, you know- … come up quite often … cable, cable
Matthew Stead: terminations, again, some really
Rosemary Barnes: basic- Yeah, that, really specific ones that were raised multiple times.
Yeah. Um, yeah, which, which is great- Yeah … ’cause it gives us a good direction to go. But I do love how it changes so much every year- Yeah … ’cause it makes me feel like, okay, yeah, like we’re actually, you know, it’s worthwhile, um, putting on another event. Mm. Um, not just recording one event and then just, you know, like replaying that every year or something.
Re-educating.
Allen Hall: Yeah. Well, I, I think there’s a learning exercise that has happened over the past two years where people now are knowledgeable about those things we talked about- Mm … two years ago. Uh, was it, was it even two years ago? It was a year and a half ago when we first started this, so we’re, we’re not that deep into it.
Although our third conference will be next March, uh, you just see more energy, more industry knowledge in some of the references that I heard, uh, in terms of other companies and the approaches they’re taking clearly came from WOMA.
Matthew Stead: Yeah.
Rosemary Barnes: Mm.
Matthew Stead: Yeah,
Allen Hall: yeah. Which is, which is [00:18:00] fascinating. Yeah. That’s
Rosemary Barnes: good. I mean, we want- It, it is
Allen Hall: sticking
Rosemary Barnes: we want tech conferences to get better, right? That was the- No … the reason why we, uh, we started this conference was ’cause we didn’t think that it was sufficient, what we had available. So, you know, it’s not a bad thing if other conferences, um, get better. Yeah. Yeah. We should also mention that blades were, were raised a fair bit.
We talked so much about blades in the previous years, and we will be talking about blades a lot again, including we’ve got a master class on the Friday. Uh, it’s… Yeah, we’ll go back to some of the basics about how the composite materials work and how a blade is designed and certified and manufactured, and, um- Lightning.
Y- yeah, yeah, a little, a little bit about lightning. Um, I don’t wanna cover it too much because we did the master class on lightning- Right … last year. Mm. Um, yeah. And yeah, some of the common damage methods anyway. And of course- Mm … yeah, lightning is probably the most- … common, or I guess leading edge erosion is the most, and then lightning would be the most expensive.
Um, yeah, so we’ll be, we’ll be covering all that and just try and raise the knowledge level a little bit, um, for [00:19:00] everybody to… It’s a very complicated kind of, uh, yeah, component.
Matthew Stead: Yeah.
Rosemary Barnes: Yeah.
Matthew Stead: And workshops. So each year we’ve run sort of workshops or roundtables or whatever, so we’re still thinking about the format for them, but, um, thinking about how we’ll reintroduce them again this year.
You know, specific topics, specific questions, specific answers.
Rosemary Barnes: Mm.
Allen Hall: And the three of us will be in Hamburg in a couple of weeks at Wind Energy Hamburg, so if you see us and you’re interested in coming to Australia, that’s the place to grab us and- Yep … and shake us and say, “I wanna go to Australia. How do I do it?”
Rosemary Barnes: Mm.
Allen Hall: Uh, yeah. Yeah.
Rosemary Barnes: Especially if you’ve got a, a t- technology that addresses some of those specific issues that we’ve mentioned- Mm … then, um, yeah, just know ahead of time that Australia needs, needs more information and more, um, solutions available to them. So, yeah. And
Matthew Stead: that reminds me, we had a really discussion a- around safety and, you know, reasonable and [00:20:00] practicable, and discussion around all the lessons learned about how…
or what is best practice on a site, what is best practice about how to manage risks and-
Rosemary Barnes: Mm.
Matthew Stead: Yeah. Yeah. I know you, you, you enjoyed that one.
Rosemary Barnes: Yeah, yeah, definitely. And we’re not talking about, like, safety the- Ear muffs or hats. The, um, rou- Yeah, the routine safety that if you- The goggles, yeah … yeah, trip over and graze your knee, then you need to let the site supervisor know.
You, you know, it’s not that stuff, ’cause sites have that under control. That’s a given, yeah. Or at least the ability to get that under control. We’re talking about the bigger- Yeah … bigger things, you know. Like, uh, is there a issue that is causing blades to fall off turbines every now and then? Is there an issue that, uh, can lead to, you know, a fire?
I, I think everyone, like- Yeah … a big fear of everybody’s. There’s never been, um, in Australia at least, there’s never been a wind turbine fire that has caused a bush fire, but it is a possibility, and it would be so bad for the industry. So, you know, it’s those things- Mm … that could be just terrible, preventing those before they happen.
Mm. So that’s the kind of safety that we’re gonna mainly focus on. Mm. Although, you know, we’re not gonna [00:21:00] turn down questions on, um, some of the smaller stuff as well.
Matthew Stead: Yeah.
Rosemary Barnes: Mm.
Matthew Stead: And we even thought about getting some lawyers-
Rosemary Barnes: Yeah …
Matthew Stead: you missed out on this discussion, Rosie. Okay.
Rosemary Barnes: Yeah.
Matthew Stead: So
Rosemary Barnes: Yeah. Lawyers, this is news to me.
Well, I mean, are we talking contracts or, um-
Matthew Stead: No, no … no … it’s really operations. I mean- Right … the environmental, um, issues- Oh yeah … the operational issues. Mm. You know, there’s, there’s a few things in there that the lawyers can add.
Rosemary Barnes: Yeah. I mean- … I’ve, I constantly find myself having to interpret, you know, legal, um, legal text and also anticipate, you know, it’s one thing about what’s the right engineering, but then there is also the legal interpretation of it- Yeah
uh, as well, you know, in terms of contract law, but then also in, in terms of safety. Yeah. Um, yeah. Was this certification done correctly? You know- Yeah … that’s got some legal aspect to it. So yeah, that- Yeah … makes sense to me. Insurance is another one where I would say- Yeah, actually that came up … you know, like some, some people might think that that doesn’t sound interesting, but yeah, in- insurance is the other-
Matthew Stead: Mm
Rosemary Barnes: aspect that you [00:22:00] just can’t, um, you can’t get away from it. Like, you can’t just think that you’re, you’re doing your engineering without bothering about Mm … yeah, like finance and law and, um, and insurance. Those are things that- Mm … you spend a lot of time thinking about.
Matthew Stead: Yeah. Mm. And I guess we would also love to hear, you know, about potential speakers, but we’d also love to hear any other topics that people are attending and want to know about as well.
Rosemary Barnes: Mm-hmm.
Allen Hall: Absolutely. And if you haven’t registered for WOMA 2027, which will be March 3rd through 5th at the Pullman in East Melbourne, right? East Melbourne, yeah. They just redefined it. It’s Pullman in East Melbourne. Uh, go ahead and go to woma2027.com and register now. Uh, Matthew and Rosemary, it’s great to see you in person again, and we’ll see you in a couple of weeks, uh, hopefully in, in Germany.
Rosemary Barnes: Mm.
Allen Hall: Very [00:23:00] exciting.

Forcing Our Teachers to Toe the Line on Communism
The substance of the meme here is correct; Florida public schools require comprehensive K-12 instruction on the history and dangers of communism, following a series of legislative moves and curriculum standards. The updated “History of Communism” curriculum is rolling out for the 2026–2027 school year, mandating that students learn about the “brutal realities” and (the catastrophic) global impact of communist regimes.
When I was a schoolboy in the 1960s and early 1970s, we came to learn that all efforts to establish a viable communist nation had failed, but our teachers were not shackled as to what they could teach and how they could teach it. As a result, we came to a variety of helpful viewpoints, and these are what I offered my own kids as they were growing up, e.g.,
- “Men are not angels,” as my sixth-grade social studies teacher explained. Those who do not need to work in order to survive can simply goof off.
- Yet idleness is averse to most people’s psychological needs to be an active and productive person, and member of society.
- Power corrupts, and absolutely power corrupts absolutely. Democracy prevents the accumulation of a pathological amount of power on the part of any one leader. (This was assumed to be true until Donald Trump’s second term.)
- If Lenin (a butcher) hadn’t had Trotsky (a compassionate intellectual) assassinated, the entirety of the USSR would have turned out completely differently.
- If the U.S. hadn’t, through its embargoes, made it impossible for Cuba to offer its people a decent quality of life, their revolution may have succeeded and brought forth a new way of thinking.
- There are examples of smaller scale societies in which the ideals of communism work out very nicely, e.g., the Israeli kibbutz.
- We read and discussed at length a book called “Social Ideals and Ideal Societies” in which these concepts were analyzed fairly and in great depth.
Now, will the typical American schoolchild turn out better if he’s cut off from thinking critically about all this and forced to accept the mantra that “communism = evil?” The typical Florida Republican would say the answer is an obvious yes, but most intelligent people would dispute that.
Producing educated people who can think for themselves is an idea quite opposed to the ongoing control of a population.

Trump Supporters Stupid?
To the author of the meme here, I say: It’s safe to say that most folks in Trump’s MAGA base are stupid, though one needs more than a low IQ to fit into this segment.
In particular, we mustn’t omit mean-spiritedness. People who are kind, compassionate, decent and tolerant of others are grossly unqualified to be rank-and-file Trumpers.
