Imagine having an air conditioner at home or work in a hot summer. You’re probably enjoying nice, cool air all year long.  

But what if your AC is blowing warm air during the summer? If your AC is constantly blowing warm air, something is clearly wrong.  

Here are 7 common reasons your AC is blowing warm air and not cooling the room as it should. We will also try to answer some common questions about it.  

How do you fix it so it cools the room properly again? And what if it keeps blowing hot air, no matter your settings or temperature? 

You should schedule a maintenance appointment with Cyanergy, but in the meantime, you’re wondering what the problem might be.  

But First, the Basics of an Air Conditioning System

An air conditioning system cools the air inside your home or office, making it more comfortable during hot weather. The system has a few essential components that help it work.  

First, there’s the evaporator, which is usually inside the house. This part takes in the warm air from the room and cools it down using a special liquid called refrigerant. The refrigerant absorbs the heat, turning it into a gas.  

Next, the compressor, located outside the house, plays a key role. It squeezes the gas from the evaporator, making it even hotter. This hot gas is then sent to the condenser. 

The condenser, also outside, cools the gas down by releasing the heat into the air outside. As the gas cools, it turns back into a liquid. The liquid refrigerant then goes back into the system to repeat the process.  

Finally, the cooled air is blown back into the room through vents, lowering the temperature. The air conditioner system has a thermostat that you can set to control how cool or warm you want the room to be.  

In Australia, air conditioners can cool and heat, making them useful all year round. During winter, the system works in reverse, heating the air inside. Air conditioners help keep homes and offices comfortable, no matter the season.

Types of AC Units in Australia

Several air conditioning systems are commonly used in homes and offices in Australia, each designed to suit different needs and spaces. 

One popular type is the split system. This system has two main parts: an indoor unit and an outdoor unit.  

The indoor unit cools or heats the air inside, while the outdoor unit releases the heat outside. Split systems are great for cooling or heating one room or a specific area of the house. 

Another option is a multi-split system, which works similarly to a split system but can connect multiple indoor units to one outdoor unit. This lets you cool or heat many rooms simultaneously without requiring multiple outdoor units. 

A ducted air conditioning system is another common choice. In this system, a central unit is connected to a series of ducts hidden in the ceiling or walls.  

The air is distributed throughout the house, making it ideal for simultaneously cooling or heating large spaces or multiple rooms. This type of system is often found in larger homes or commercial buildings. 

There are also small portable air conditioners that can be moved from room to room. They are easy to set up and don’t require installation, but they are usually less powerful and only suitable for cooling smaller spaces. 

Finally, window air conditioners fit into a window or wall opening. They are more common in older homes and are designed to cool a single room. 

Each type of air conditioner has advantages, depending on the space size and how much temperature control you need. 

How Does Air Conditioning Work? The Science Behind AC System

Air conditioners come in different shapes and sizes, but all work similarly. They use a special liquid called refrigerant to remove heat from your home or office and blow cool air inside through vents. 

Turning on your AC keeps repeating this process until the room is as cool as possible. Warm air inside the house is pulled into the AC and passes through a cold coil filled with refrigerant.  

The refrigerant absorbs the heat, turning from a liquid into a gas, and the cooled air is sent back into the room. 

The refrigerant gas is then sent to the outside unit, where it is compressed. A large fan pulls in outdoor air, which cools down the refrigerant, turning it back into a liquid and releasing the heat outside. The process repeats to keep the indoor space heated or cooled. 

7 Common Reasons Your AC Is Blowing Warm Air

Condenser Coils are Dirty or Blocked

One reason for warm air could be dirty or blocked condenser coils. These coils are in the outdoor unit; the air conditioner can’t cool properly if dust or debris is blocking them.  

You can clean the area around the outdoor unit yourself, but it is recommended that you have the condenser coils professionally cleaned at least once a year. Ensure plants and other things are kept from the unit for good airflow.  

Refrigerant Leaks

A small amount of water or condensation around your air conditioning unit is standard. However, if you see a sudden increase in water leaks or condensation, especially from the ceiling or outlets, it’s time to talk to an expert to check for leaks or refrigerant issues. 

Air Filters are Dirty or Need Replacing

If your air conditioner is set to cool but blowing warm air, there’s a problem. A common reason for this is dirty or old filters. Filters are the first defence against dust and bacteria in the air.  

When they get dirty, airflow is blocked, and the system can’t cool the air properly. It can also make the unit noisy and lead to health issues like asthma and allergies. 

You can clean the filters by removing the front grille, locating the filter panel, and vacuuming the dust.  

You can wash the filters with lukewarm water and mild soap and let them dry in the shade. If that doesn’t help, you might need to replace them, so it’s best to call an expert.  

Damaged Compressor

If your air conditioner is blowing hot air even though the thermostat is set correctly, it could indicate a damaged compressor.  

If basic maintenance, like cleaning the filters and coils, doesn’t help, it’s time to call an expert. A broken compressor can prevent the unit from cooling properly, and the sooner you get it fixed, the better.  

The Return Duct is Broken or Disconnected

Your air conditioner might be blowing warm air because the return duct is broken or disconnected. When this happens, the duct can pull in air from outside, which isn’t cooled, causing the air inside your home to feel uncomfortable and warm—especially during hot summer days.  

Evaporator Coils Have Frozen

Evaporator coils remove heat from the air inside your home to cool it down. However, if too much moisture builds up on these coils, they can freeze. When this happens, the cooling process is disrupted, and the system can’t transfer heat properly.  

The Outside Unit Not Getting Enough Power

air conditioners

If the outdoor unit isn’t receiving enough power, the evaporator fan will stop running, and the AC won’t work correctly. Check that the outdoor unit is getting power by looking at the electrical panel. If the breaker has tripped, you can reset it to restore power.  

What to Do When Your AC Blows Hot Air

Check the Thermostat Properly

Ensure your thermostat is set to “cool” and the temperature is low enough. Sometimes, kids or simple mistakes can change the settings, so double-checking and adjusting it might fix the issue quickly.  

Check the Breaker Switch

Most AC systems have both an outdoor and indoor unit. If the indoor unit works but the outdoor one has no power, the AC might blow hot air.  

Check the breaker switch. If it has tripped, flip it back to “on” and let the AC run for a few minutes. If it trips again, contact a professional.  

Check the Filter

A dirty air filter can block airflow, making your AC work harder and blowing hot air. It also spreads dust and allergens throughout your home. During hot months, replace the filter at least once a month to keep the system running smoothly and efficiently.  

Check for Ice on the Outdoor Unit

If you find ice on your AC, turn it off and let it melt completely. Check the air filter to make sure it’s not causing the problem.  

Install a clean filter once the ice has melted, and try turning the AC back on. If it’s still not working, call a professional for help. Avoid picking or chipping the ice, as it can damage the system.  

Check for Debris Around the Outdoor Unit

Leaves, dirt, and other debris can build up around the outdoor unit and make the AC blow hot air. Use a broom to clean the area and trim grass and plants to ensure good airflow.  

Keep Your AC Running Smoothly with Regular Maintenance

Regular Maintenance: Schedule an inspection and cleaning every spring to catch minor issues before they become big problems.   

ENERGY STAR Appliances: These appliances use less energy, helping to keep your home cool while saving on electricity costs.   

Improve Insulation: Insulation keeps the cool air inside. Spray foam insulation is an excellent option because it can be added to existing structures and provides a tight seal to keep your home comfortable.

Welcome to Uptime Spotlight, shining Light on Wind. Energy’s brightest innovators. This is the Progress Powering tomorrow.

Allen Hall: Howard, welcome back to the show. Thank you. Well, we’ve been traveling a, a good deal and talking to a lot of operators in the United States and in Europe, and even in Australia. And, uh, your name comes up quite a bit because we talk to all the technical people in the world and we see a lot of things. And I get asked quite a bit, what is the coolest technology that I don’t know about?

And I say, Howard Penrose MotorDoc. And they say, who? And I say, well, wait a minute. If you want something super powerful to learn about your turbine, that is easy to implement and has been vetted and has years of in-service testing and verification. It is MotorDock, it is [00:01:00] empower for motors, it is empath for systems and vibration and all the other things.

And now empath, CMS, which is a continuous monitoring system that you’re offering that those systems are revolutionary and I don’t use that word a lot in wind. It’s revolutionary in wind and. Let, let me just back up a little bit because I, I want to explain what some of these problems are that we’re seeing in the field and, and what your systems do.

But there’s a, the, the core to what your technology is, is that you’re using the air gap between the rotor and the stator and the generator to monitor what’s happening inside the turbine. Very precisely. Can you just provide a little insight like how that magic happens?

Howard Penrose: Okay. It’s, it’s basically, we use it as an, as a basic accelerometer.

So, um, the side to side movement of the, of the rotor inside the air gap. Um. I could get very technical and use the word [00:02:00] inverse square law, but basically in the magnetic field I’ve got side to side movement. Plus every defect in the powertrain, um, causes either blips or hesitations in the rotation.

Basically, the torque of the machine, which is also picked up in the air gap, and from a physics standpoint. The air gap, the magnetic field, can’t tell the difference. And, um, both voltage and current see that as small ripples in the wave form, and then we just pull that data out. So, um, uh, I, I liken it exactly as vibration.

Just a different approach,

Allen Hall: right? And that that vibration turns into little ripples. And then I’m gonna talk electrical engineering, just for a brief moment, everybody. We’re taking it from the time domain to the frequency domain. We’re doing a four a transform. And in that four a transform, you can see these spikes that occur at, uh, known locations that correlate back to what the machine is doing

Howard Penrose: exactly.

[00:03:00] They’re they’re exact calculations, uh, down to the hundred or even thousandths of a hertz. Uh, so, uh, when we, when we do the measurements, they come up as side bands around, uh, whatever. The, the, uh, signature is, so the amplitude modulation, it’s an amplitude modulated signal. So I have, uh, basically the ripple show up on the positive side of the waveform and on the negative side of the waveform.

So around everything, I just have plus and minus line frequency. That’s, that’s basically the primary difference. Then we just convert it over to decibels, which makes it, um, relational to the load, which means load doesn’t matter. Uh, so I can compare an unloaded machine to a fully loaded machine and get the same results,

Allen Hall: which is also amazing.

So the load, what the turbine is doing doesn’t really matter at all, as long as it’s rotating and producing power. You can [00:04:00] monitor what’s happening, sort of anything up, and then the cell. Mostly,

Howard Penrose: well, it’s even, it’s even more fun than that because the air gap in a wind turbine is at a fixed speed for a dfi.

So, uh, it’s constantly turning at the exact same speed, which is basically all I need regardless of the physical speed. So, vibration, I need to know that physical speed and electrical signature. I need to know the air gap. Speed.

Allen Hall: So with this data and the way you’re monitoring what’s happening on the turbine is through current sensors on the feeds and voltage probes.

You could do one or the other and, and you’ve done both, and we can discuss that for a moment. But just using the what’s happening on the wires, on the generator wires, now he can determine everything that’s generally happening mechanically. So from gearbox to the blades. The, [00:05:00] the hub, uh, you can even determine things that are happening up tower a little bit like ya motors and that sort of thing.

If they’re acting weird, you can see changes there. And it’s sort of like the pulse of the turbine

Howard Penrose: and the main bearings. And the main bearings, right? So all the bearings never leave out the main bearings. That’s, that’s a study we’re involved in right now. So, um. Yeah. Uh, oh. Yeah. The, the study right now is, uh, we’re using the technology to map out circulating current sub tower.

Um, so we’re, we’re looking at, uh, why main bearings are failing, um, which was missed before. I’ve got an, I’ve got a paper coming out on it. We’re kicking off an NRE L study, uh, on it. And we are also working along with, um, groups in the field and an independent study all to. Well, a main bearing is a really expensive issue.

Um, and, and we’re fine. People are just [00:06:00] finally figured out that they were failing because of electrical discharge. And, um, the high frequencies associated with that basically caused the brushes to become resistors and the bearings to become conductors. So, uh, we now have a technology that allows us to look at these very high frequency sound or.

High frequency

Allen Hall: noise. Okay. Let’s just use that as a test case for your system for iPath CMS, because. That is one issue that pretty much everybody in the United States that uses a particular OEM has

Howard Penrose: actually, uh, you, you got, you hit it on the head. It’s just like the old W Ring thing. Everybody thought it was a specific, uh, generator manufacturer turned out to be every DFI failing the same way we discovered that.

Uh, we’ve also heard, uh, you know, a specific OEM and a specific. Type of platform. They were seeing the problems in the main bearings. And again, it just came about because people were talking about it. Except [00:07:00] guess what? We’re not just seeing it in the us, we’re seeing it globally. That’s one of the benefits we have with so many users worldwide is we’re finding out that all of these problems are not unique to us.

They’re global in nature and they’re cross platform.

Joel Saxum: So when we talk cross platforms and, and you, the listeners here will notice that I’ve been markedly absent from the conversation so far. ’cause it’s a bit over my head. Sorry. No, it’s, it’s just, this is, this is great stuff. But what I, that was one of the things I was wondering while we were going through this is we were talking about, um.

Solutions that you guys have that can solve specific problems. Now, does this say I have a direct drive turbine? Or like, is, is there any models or any types of technology that you can’t work on out in the field or does it Basically we have a solutions that can cover all turbines regardless

Howard Penrose: if it’s got a magnetic field, whether it’s a generator, motor, or transformer, we can see it.

I can follow that. So we even, we even, we even use [00:08:00] the technology in the industrial side for power monitoring for plants. Because we get, uh, we get good insights on what’s coming into the facility and what the facility’s putting back into the system, in particular with high frequency noise and stuff like that, that utilities are just now starting to pay attention to.

Joel Saxum: It’s just, this is an important thing for the CMS system that you guys have, because I’m, I’m thinking right now, okay, now, now again, I’m gonna dumb this way down, um, in my. Built Jeeps that I’ve done in the past, I’ve gotten death wobble in the steering wheel because of oscillations in the front axle.

Right? But that only happens at a certain speed, right? If I, if I could, if I could get through second gear at about 4,000 RPMs and grab third, I’m fine. But if I have to shift to 2,500 RPMs, about 32 miles an hour, I’m in a world of hurt, right? I’m, I’m shaking this thing down the road. So turbines I know will do that sometimes at certain RPM.

They will have vibration issues that will either go away or expand a resonance or natural [00:09:00] frequency.

Howard Penrose: Yeah,

Joel Saxum: right. Like at, at at, um, you know, four RPM is one thing at seven and a half rpm it goes away. So having cm, your CMS system, that’s their continuously monitoring when the wind speeds are low, when they’re high, when.

Does that help you pick up different anomalies within the turbine to be able to kind of pinpoint what’s, what could be happening?

Howard Penrose: No, because those frequencies are always present. They just amplify at certain points in speed, right? They, they hit a natural frequency, so they just oscillate like mad. Uh, I’m rereading all of my Tesla books right now.

So where, where he talks about that, you know, you could split the world like an apple if, if you hit the right frequency. Um. With a small device. Uh, so, uh, yeah, we see it across that entire speed range, even though you feel that oscillation. One of the nice things about, um, uh, electrical and current signature is it isn’t a structural vibration analysis.

Like if, if I [00:10:00] have the, um, structure or the machine vibrating outside, I see very little of that. I see all the drivers behind it instead. Right. So it, it’s, it’s less likely, uh, I’ll pick up a false positive because I hit a resonance. That amplitude remains the same.

Joel Saxum: That’s the difference between what you guys are doing and what and what everybody else is doing with a accelerometer, gy, gyro, whatever that sensor may be.

You name it,

Howard Penrose: accelerometer, ultrasound, all that other stuff. It’s all variations of,

Joel Saxum: of physical.

Howard Penrose: Yeah, and I refer to those as basically fault detectors. They’re dummy lights. Nobody’s actually using condition-based maintenance as condition-based maintenance. We can use the information to actually make modifications and changes.

Joel Saxum: You can actually diagnose with yours. That’s what we always say right now. CMS basically at, at this, at a general level is go and look at this turbine, bing. Go and [00:11:00] look at this turbine. You have a problem. Go and look. One of these blades has a problem. Go and look at it. But you are actually going deeper down saying diagnosis, Hey, this may be the actual problem that’s causing.

This issue in your turbine, and that is invaluable.

Howard Penrose: Yeah. One of our case studies is of a bearing a man, a a a a re, a reinstalled bearing on a, or an installed bearing on a drive end of a a wind turbine. The, um, it had some problems with, uh, the cage, which caused one of the roll balls not to rotate. Um, and it had some false brunel on in the inner outer race, and we saw that, but we also saw, uh, a much higher level in the thrust bearing in the gear box.

And so when we, we went back to them and said, yeah, you’ve got a problem here. Uh, they took the bearing back off, and then I said, make sure that you’ve got all the shims in the. And the, uh, coupling and they had left out a shem, so it had [00:12:00] caused a problem in the, so if we hadn’t detected the other thing, we would’ve detected the gearbox, um, bearing.

But they were ignoring that data and were looking at the bearing. They just replaced in the generator. So when, when they put everything back together, we were able to confirm that. All we saw after that was the friction losses in the, in the bearings.

My

Joel Saxum: question is, is okay, we’re looking at. Basically deltas outside of a, a sine wave and these peaks and valleys to in your, in the sign you’re detecting, how are you able to know, oh, I saw this delta here, or I saw this here.

That’s a thrust bearing. That’s a main bearing. That’s something here. Is that just years of knowledge built up from, okay, we saw this fault and we, we figured it was this because of it, or. How are you guys arriving at that?

Howard Penrose: Uh, it’s from my years as a, uh, vibration analyst, um, Navy trained vibration analyst.

Uh, [00:13:00] so, um, what, what was discovered by Oak Ridge National Labs in the 1980s? So this isn’t that new. As a matter of fact, this technology is direct descendant from Howard Haynes’s work another Howard. What we discovered was the frequencies are. For the most part, exactly the same as what we look for in vibration, just side bands, right?

Because we, we, you know, I tell people, how do you interpret the data versus vibration? Stand on your head and cross your eyes. Um, being former Navy, I sometimes use some other, you know, things such as go out and drink heavily. Uh, but in any case, um. Instead of looking from bottom up, we’re actually setting whatever the peak line frequency, current or voltage is, that’s zero.

And then we, uh, relate every other peak, um, based upon 20 times the log 10 of the difference in the current, from the current in [00:14:00] question back to that peak. Which is kind of cool because that also means that it’s. As my load changes, everything follows. So it’s not load dependent. The only thing that happens is frequency.

So you have to take enough of a, a data across a long enough time so that you can determine the differences between the, the components, right? So, so in a wind turbine for instance, I’ll have all those bearings in the gearbox, including the planetary gears. I have the main bearing, and they all kind of crowd around line frequency.

I need a resolution that’ll show me a hundredth of a hertz difference between any two peaks. It’s it’s vibration. It’s actually vibration. So the, each of the components, even each component of the bearing, ’cause I can call out which part of a bearing, and that’s actually how we analyze what conditions we’re looking at.

If it’s, uh, cage and ball only, and no signature off of the inner and outer [00:15:00] race, chances are it’s lubrication. Um, you know, that kind of thing on a main bearing. If I see the outer race cha and nothing else, chances are, uh, they didn’t clean out all the old grease and there’s dried grease across the bottom.

Uh, we discovered that actually with a couple of the, a couple of sites. So we, we say check, check greasing and condition of the inner and outer rays, you know, that kind of thing. And, uh, we’ve been right more than wrong. Uh, the, the quoted, the quoted number back from one of the OEMs is about 95% accuracy.

And when you consider, when you consider borescope has been identified at less than 50%, um, it, it, it gives you a really high accuracy.

Joel Saxum: We just had a conversation with someone the other day, Alan, you and I, about borescopes and how can you borescope so think that’s full of grease And they were like, oh, yeah.

Allen Hall: Yeah, it’s difficult.

At best. Well, and that’s the power of [00:16:00] what Modoc is doing, and what Howard’s doing is that it can detect a range of problems early. And as we get into this area of where o and m budgets are becoming restricted, and you need to spend your money wisely. Do preventative maintenance, which is what MotorDoc is all about, is catching these things early before they become really expensive.

Electrical signal analysis is a very simple way to get that data, which is what the Empower Empath and then Empath CMS system are doing is they’re, they’re reading those electrical signatures and correlating back to where the problem is and the success rate is. Howard, as you pointed out, is. Really high, uh, a lot of systems that I see and I was just went to Europe and looked at some data on some other systems, it’s about 50 50.

Well, if 50 50, I could flip a coin at that point. It’s not of any use to me. It has to be somewhere north of 90 where I become interested. And your system, when I talked to operators that use it, [00:17:00] said, well, geez, um, you know, it’s well in the high, in the nine high nineties all the time and it’s amazing what they can pull out.

It’s this bearing or that bearing or this problem with this motor or this problem with the system and the amount of money they’re saving to pick up those problems early and to get them repaired when it’s lower cost or to keep an eye on ’em even, which is an option, lowers our operational budgets down and it makes sense.

So the, the cost of a CMS system is only relative to the money it saves. And I think this is where a lot of operators are getting a little hung up. There’s a lot of CMS systems, which are you pay per year for, and it’s a constant expanse. It adds up to the om OMS budget and no one wants to do that. What you’re seeing now with MotorDock is that system is a capital expenditure.

You buy it, it comes with the hardware, it comes with the [00:18:00] software, it comes with all the knowledge and all the updates I think are free. So. It makes a lot more sense to use a MotorDoc type of system and empath CMS than necessarily to, to put individual CMS systems on that maybe do less than what Howard can do.

Joel Saxum: I think an important thing here too, Alan, is as we get to, uh, an era of lifetime extension, I. People looking for that solution. How do I guarantee the safety of my turbine, the operation of my turbine as we continue to roll this thing forward? I know here, even in the states, we always say PTC, 10 year repower.

That’s not the case for all these turbines. We have 80 20 repowers. We have a lot of ’em. Like, Hey, we have a good PPA. So these things have been, these are 14 years old, we’re still gonna run ’em. We’re not repowering these, or in Europe or in other places in the world where we don’t have the same kind of tax setup we do, where they’re trying to squeeze as much life outta these in, you know, originally 20 to 25 year lifetimes.

Man, if you can put something on there that can tell you you’re good to go, or Hey, you need to watch this, or This is the next big spend you have coming up, they can help those operators to make decisions [00:19:00] to for lifetime extension in a really, really good way.

Allen Hall: Going into the data acquisition system and how it connects to the turbine, I know it’s one of the problems that we run into occasionally, is using anything that the the Tower has in terms of data streams.

They want of a lot of it information. Does your system plug into the data system of the turbine or is it independent, or how does that work and what is the security features?

Howard Penrose: Yeah, whatever they want. So, uh, that, that, and, and you bring up a good point, like wireless is not allowed. Um, but everybody’s using it, right?

Um, there’s a lot of things that aren’t allowed that we were, we were. Privy to during NIST’s work and, and others’ work on cybersecurity on the hill, because I was advising that stuff back in the, you know, back, uh, prior to 2020 and a little bit afterwards. Um, so, uh, uh, [00:20:00] yeah, we, our system was originally designed for nuclear power plants.

So, uh, it’s meant to either. It’s a wired system basically, that you can take back to an independent server. You can have it go locally and send it through your own, uh, own network. Um, it doesn’t need to connect to cloud or somewhere else. Uh, if you want to keep it itself contained. Uh, in some turbines we have gone the route of, uh, cellular modems.

For, for each of the towers. Um, you know, when, when they’re permanently installed, a lot of people just do data collection. I mean, when you consider, like in a GE turbine, um, if I go, if I personally go to a site and I’ve done over 6,000 turbines in the, in the US and Canada myself, um. And if you could see me, you know, I don’t climb.

[00:21:00] Um, yeah, that’s my running joke. It’s like, yeah, I don’t think the ladders will support me. Uh, but any case, um, the, uh, normally it’s walking the base of the tower gathering data as long as the transformer’s down tower and moving on to the next one, I, I think my record is seven minutes a tower, including traveling in between.

So it’s not unusual to knock out a single data collection on a site within, uh, if it’s 120 turbines, normally three days. Three and a half. If there’s a, if it’s summer and they’ve got that wind break in Texas where, you know, it’s changing direction, so it takes a lunch break.

Joel Saxum: You’re a small company, right?

Just like we are here at Weather Guard where we’re flexible to what the client wants. So if the client wants a certain thing, we can deliver a certain thing. If the client needs this, they can, we can do this. So you get, you guys can do the, the CMS UPT Tower where it’s like you have an installation and it’s gonna be there.

Or hey, we can just come to your site, boom, boom, boom, do some testing, and be outta there and give you some reports like you can, you [00:22:00] have a lot of solutions that you can help people out with.

Howard Penrose: We even have, uh, most of the, um, uh, wind service companies, you know, motor repair shops and generator repair shops and everything else have our technology.

They also provide the service. Uh, that’s our model is the more the end users or service companies can do it, the better. Uh, we, we made the choice not to, you know, I don’t want a room full of people that are sitting there doing nothing but analysis, right? They’re gonna burn out. Uh, I’d rather be doing the research and identifying the problems, finding industry related issues to solve.

And our technology was built simple enough that we don’t have to handle a lot of tech support calls. Um, and, uh, and monitoring is an option. Meaning we’ll do the monitoring. I’ve got, I’ve got a number of industrial sites, some wind sites, some other energy sites. Uh, [00:23:00] all, all using the technology and getting us data, but yeah, exactly.

Smaller company. It’s broad, but the technology is not backed by just us. It’s backed by a small $12 billion company called ome. So, uh, yeah, so, and that’s not, it’s not an investor anything. It’s, they, um, they got the license from Oak Ridge back in 1991 or two and, uh, and they maintain it. And during some 97 on, uh, I, in different roles.

Uh, have been supporting the development of the technology. So we have a mutual agreement. They focus on, um, nuclear power, and I focus on everything else.

Allen Hall: Howard, we love having you on the program because your technology is just amazing and people need to get a hold of MotorDoc. So if you’re an operator, a developer, an OEM, and Wind, if you’re making some of the components for wind [00:24:00] turbines, you need to be talking to Howard and MotorDoc to get this diagnostic tool into your toolbox and save the the world a lot of money on downtime and repairs.

Howard, how do people get a hold of MotorDoc? Where do they find you on the web?

Howard Penrose: Well, we could be reached online, uh, through, uh, LinkedIn at, uh, LinkedIn slash in slash MotorDoc, or, uh, at our websites MotorDoc.com or MotorDoc ai.io. Uh, or you can also reach us via email at info@motordoc.com.

Allen Hall: Howard, thanks for coming on.

We’re gonna have you back on soon and everybody keep watching Howard on LinkedIn if you wanna find out what’s happening as MotorDoc develops more technology, watch Howard on LinkedIn. Howard, thank you so much for being on the program. Love having you.

Howard Penrose: It has been a pleasure as always. And we’ll see you the next time [00:25:00] around.

Data Center Load Uncertainty Dominates Georgia Power IRP Hearing

Published

on

Under state law, every three years, Georgia Power must show government regulators at the Georgia Public Service Commission (PSC) its plan to meet electricity demand over the next 20 years. The Commission then must either approve, deny, or amend what is typically a multi-billion-dollar plan that ultimately shows up on your electric bill. Georgia Power’s profits depend on the amount of spending approved in the plan. This year, the review is particularly important because customer bills have already skyrocketed due to two new nuclear plants and high fossil fuel prices. 

In its new plan this year, Georgia Power told state regulators that its customers would need a 50% increase in power in just six years, requiring a historically massive buildout of new power plants. For the last fifteen years, despite economic and population growth, most utilities around the country have seen slow or flat demand growth because appliances have become more efficient and now use less energy.  

In a hearing to review the plan, multiple experts testified that Georgia Power’s forecast is highly unlikely, even with expected growth in huge new computer data centers. Why is this so important? Because if the Commission approves the plan and the projected new demand doesn’t show up exactly as Georgia Power expects, existing customers will have to pay for billions of dollars of unneeded power plants. 

Huge Projected Computer Data Center Expansion Would Increase Fossil Fuel Usage

In order to power the projected electricity demand from huge new computer data centers, Georgia Power proposes to keep its old, inefficient coal-fired power plants (over 4,000 MW of coal-fired capacity) operating through the mid-2030s, when some will be over 60 years old. These plants have emitted an average of 10 million metric tons of carbon dioxide per year over the past few years. In previous Georgia Power resource plans, these plants were going to retire to reduce costs and health impacts. 

Georgia Power also proposes to double down on building many new gas-fired power plants (8,000-9,000 MW of gas-fired capacity) that would make the state’s economy fundamentally dependent for another fifty years on out-of-state oil and gas drilling. We estimate that the new gas power plants alone are likely to emit over 16 million metric tons of carbon dioxide emissions per year for decades. 

The coal and gas power plants would be by far the largest source of air pollution in the state, spewing tiny, toxic particles that cause heart attacks, asthma, and climate change.  

Experts Decry High Electricity Demand Forecast

Seven highly qualified experts hired by different interests disagreed with Georgia Power’s assumptions around demand forecast driven by data center expansion, and none endorsed them. For instance, a national electric reliability expert hired by SACE, NRDC, and Sierra Club testified that Georgia Power’s forecast was “malpractice.” Even the PSC’s own staff poked holes in Georgia Power’s demand forecast.

Expert witnesses Stenclik, Richwine, and Goulding; sponsored by SACE, NRDC, and Sierra Club:

Here is a list of the witness panels that had broad or specific issues with the demand forecast, and timestamps for the hearing video so you can listen to their critiques yourself.

Next in the process, Georgia Power will file rebuttal testimony and have a hearing for that rebuttal. Intervenors and Georgia Power will then file final briefs, and the Georgia PSC will decide what to do with this IRP in July. The PSC is an elected body that oversees the work of utilities in the state. Georgia Power, which generates over $7 billion in revenue annually, is the only electric utility regulated by the PSC in Georgia.

National Drive Electric Month: [Insert Your Town Name Here]

Published

on

The author would like to credit and thank Karen Freedman, co-chair of the League of Women Voters FL Clean Energy Action Team, for her contribution to the content contained in the article.

National Drive Electric Month 

National Drive Electric Month (NDEM) is a nationwide celebration that highlights the benefits of electric vehicles. This fall, events will be taking place across the country to help educate the public on the cost-effectiveness, public health and environmental benefits of electric transportation. It’s an opportunity for members of the public to see a wide variety of electric models in one place, talk to EV owners and have their questions answered. The campaign is presented by several national organizations that offer fantastic resources, but the real secret sauce of the events are the volunteers that help coordinate them and the EV drivers who participate as peer-to-peer EV ambassadors.

Here is everything you need to know to host an event and share the benefits of EVs with your community.

Consider Organizing an Event

This year’s event window runs from September 12 through October 12, 2025. Anyone can create an event and the NDEM website makes it easy to create an individual event webpage to promote the event. 

Advantages of creating an event through the NDEM platform include

  • Adding your event to an interactive US map & event list
  • Creating an individual event webpage
  • Making email notifications easy with registered EV owners & interested attendees
  • Providing access to how-to guides, a social media toolkit, templates, Canva, sponsor logos, hand outs, etc.
  • Receiving free banners/signage, educational handouts and swag
  • Providing access to free event-planning webinars

Organizing an Event 101

Reach out to your local municipality and see if they would be interested in co-hosting the event. Partnering with your municipality can help with identifying access to a venue, co-promotion and the opportunity to piggyback on an existing event. You can ask your mayor to create a proclamation celebrating the event. Also consider partnering with your local utility as well as civic and environmental organizations. When selecting the date and location look for a site that is walkable and accessible to attendees with varying levels of mobility. A community park that is visible will attract more participants day off than an area on a busy highway. Also consider amenities like shade, restrooms and access to food. 

Publicity Considerations

Start promoting the event early with flyers and posters that include:

  • Date, time, location 
  • Event website
  • Contact info
  • QR Code
  • Photos 
  • National & local sponsors’ logos
  • Description w/ Buzzwords: FREE, Family-friendly, EV showcase, Local EV owners share enthusiasm, etc.

Ask your local library, local business, restaurants and schools to display the poster. 

Here’s a beautiful example from the Lakeland National Drive Electric event in 2023.

You can also post your event online to various community calendars and social media venues. You can create press releases that can be sent to your local radio and television stations, community newspapers and local magazines. 

Event Considerations

Having a volunteer check-in the EV drivers who will display their cars and direct them to where they park will provide great structure and set the tone for a successful day. The sponsors provide printable signs that EV drivers can display on their vehicles to help explain the models to participants.

Having an education table with resources including multilingual versions is vital to connecting with attendees. Consider having a knowledgeable volunteer(s) be ready to answer questions. You can also have an EV quiz game and spin wheels to engage participants.

Other details to consider include having a kids’ table with coloring sheets that can occupy children while you talk to the adults they are accompanied by. Also, consider getting a prize(s) donated that can be given away as a drawing and having folks sign up so you can continue to connect with them after the event.

Get additional modes of transportation and electric equipment on display like:

  • E-bikes
  • Electric school buses and transit buses (contact your school district and transit authority)
  • Electric lawn care equipment (local homeowner or yard care company)

Finally, try to get either a ride component (if EV drivers are comfortable driving attendees in their EV) or a drive component where participants can drive an EV. Reach out to local car dealerships to see if they would be interested in bringing a representative and vehicle for the event. 

Post Event Considerations

One important aspect of the National Drive Electric Month events website is that you can update it after the event with photos and statistics like how many vehicles participated and how many attendees you talked with. It’s also great to send thank you correspondence with the EV drivers, volunteers, and local government representatives who helped pull off an amazing event. 

Get Started Organizing

National Drive Electric Month events don’t need to have a ton of vehicles to be impactful. If you have an interest in helping educate your community about electric vehicles, take the plunge and organize one this year. Not sure yet? Learn more about organizing an event by looking at the NDEM planning guide, Getting Started As An Event Organizer.
