An animation historian on Reddy Kilowatt, the cartoon charged with electrifying everything in the early 20th century.

With all the attention paid to electric vehicles and heat pumps, the 2020s might seem like the decade of home electrification — but nothing might ever rival the boom of the original Roaring Twenties. By 1929, 70% of all American homes had access to electricity, double the figure from the beginning of the decade – bringing home electrification from minority to majority.
Home electrification was so big back then, it even had a mascot: Reddy Kilowatt. Invented by a marketer at the Alabama Power Company in 1926, this cheery spokescharacter with a lightning-bolt body and a lightbulb nose was licensed to hundreds of utility companies throughout the greater part of the 20th century to promote electricity – and more specifically investor–owned utilities. Reddy was even used as a tool to link government-owned utilities to socialism or communism in years following World War II.

I first came across Reddy Kilowatt last year when a climate tech peer emailed me an image of him, probably from the 1950s, powering everything from a hot water heater to a record player with the headline “Your all Electric Home.”

For weeks I couldn’t stop thinking about that headline because I kept hearing people in the decarbonization movement say similar things (does Electrify Everything ring a bell?). Itching to learn more of the history of Reddy, I reached out to an expert.
Dr. Kirsten Moana Thompson is a professor at Seattle University who teaches and writes about animation. Her paper, Live Electrically with Reddy Kilowatt, Your Electrical Servant, explores the history of this “phenomenally successful and ubiquitous spokescharacter.”
I chatted with Dr. Moana Thompson over a video call from her office where a framed illustration of Reddy Kilowatt hung behind her. I went into the call thinking about positioning this article, “Is America ready for another Reddy?,” but by the end I learned he may be best left in the 1900s. The following interview was edited for length and clarity.
Mike Munsell
Can you introduce yourself and tell me how you ended up researching Reddy Kilowatt?
Dr. Kirsten Moana Thompson:
I'm a professor and chair of the film and media department at Seattle University, and Reddy Kilowatt was part of my research into animation that has been used in sponsored media — that is media used for non-traditional, non-entertainment purposes to do something else, like sell something, instruct you, persuade you. It forms a chapter in what will be a new book coming out in the next couple of years on animation and advertising. I think Reddy Kilowatt is a great example of how popular it was in the post-war period to use animated spokescharacters to sell products or ideas.
Munsell:
I’m curious: Are animated mascots less prevalent today than back in the post-war period?
Thompson:
My research doesn’t focus on the contemporary era, so I couldn't give you a precise example. But certainly, as late as the ‘70s, animation characters still were extensively used to promote products, not just cereal, and toys, but things like bubble bath and candy and, well into the ‘70s, alcohol as well.
There are lots of reasons for that, because certain types of animation were fairly cheap to produce, were appealing, often comedic, and attention grabbing. They were a great means to sell a product — also great to use for abstract or more complex processes, like, how do you make oil or petrol or gas? How do you convey a concept like capitalism? Animation, as opposed to live action, was often a more successful way to convey or target topics of that nature.
We have to anthropomorphize the things that are too abstract, too conceptual, or too inhuman to make them translatable into something that we can comprehend and relate to. Hence the Geico lizard or the Aflac duck.
Munsell
And that makes sense then for Reddy Kilowatt to advertise electricity back when it was new, right?
Thompson
Yes, it really emerged around the time electrification was in two thirds of American households — by 1930. And electrical utility companies needed to find an appealing way to sell their product and to encourage consumer consumption of things like appliances, which themselves were emerging — things like dishwashers and washing machines and hair dryers and so on. But also rural electrification, and electrification for business purposes and factories, and on farms.
[Reddy Kilowatt] emerged targeting a fairly affluent consumer, by, for example, turning electricity into a servant – an abstract servant that was personalized and anthropomorphized.
But it was also a way of rather cleverly justifying rate increases as well, which occurred a little later, by making Reddy Kilowatt literally a figure that earns wages and was regarded as an employee by many electrical utility companies. So it's a clever way to say to people, hey, everybody deserves a wage and Reddy Kilowatt deserves a wage and prices are going up, so we're going to put his wages up. And that's a fair thing.

Munsell:
The Smithsonian has a huge collection of Reddy Kilowatt material. Did you get to go check that out?
Thompson:
Yes, I did. The archives are extensive. And so you can read all about how [Reddy Kilowatt creator] Ashton Collins promoted the product, and what the kinds of speeches that he gave to many other business companies and electrical utility companies in the 30s and 40s.
But he's part of a wider movement. There are other leading figures like Walt Disney and Walter Lantz, who were animation studio heads. Walter Lantz, of course, ran what he would pick the Walter Lantz studios that produced Woody Woodpecker and Andy Panda, and a number of other popular cartoons of the 40s. And Walt Disney, of course, we're all familiar with. But they all believed that the kinds of skills that animation studios were doing in the 1940s — by making cartoons to train troops to operate machinery or rifles, and by making propaganda to translate the values of the fight for democracy against fascism — they believed that those skills could be applied to the commercial market in the post-war period. And that animation was a key element of visual culture that could translate to a sometimes illiterate population or partially illiterate population.
So Ashton Collins is not alone there. He's part of a broader movement in the film industry and in the animation industry, to understand the unique power of animation to communicate and to sell and persuade.
Munsell
Did you find anything in your research particularly surprising?
Thompson
In addition to extensive print materials in the Smithsonian, you see dozens and dozens of objects that featured Reddy Kilowatt. His image is on everything from stickers to comic books to toys, and other giveaways for kids to little marionettes, and robots, which were used in trade shows and trade fairs. [Author’s note: eBay has an extensive Reddy Kilowatt collection]
It was used in the 1939 World's Fair, for example, to communicate and to encourage the public to interact with Reddy Kilowatt as if it was a real figure. I was quite taken with this – it's really an early form of animatronics. They were using an avatar, a spokescharacter, who was fairly ubiquitous in the American home, on people's electricity bills, and combining it with a large three dimensional object with a record player attached and somebody who operated the speaking, to interact with kids at fairs and to communicate basic ideas. So that was really exciting in a way because it shows how ahead of its time Ashton Collins was at understanding interactivity.
Mike Munsell
I was thinking about copyright and trademark law and the public domain. Reddy Kilowatt was, in his original form, created in 1926. We're coming up on that 100 year mark. Is there a chance he enters the public domain?
Dr. Moana Thompson
I'm not sure about that. Because you can renew copyright. Which of course Disney did repeatedly before it finally had to succumb to the end of copyright. And Reddy is also a trademark as opposed to a copyrighted image. So he has not just appeared in what is public access now, some of his films and TV commercials, but he's also a trademark figure that has a continuing commercial currency. And Ashton Collins was absolutely rigorous at paying attention to trademark law. He sued other companies that had similar characters, like Willie Wired Head.

I suspect that Xcel Energy [who now owns the rights to Reddy Kilowatt] is going to be very strict in policing its trademarks. Because if this product has value as a commodity of nostalgia for a certain generation, or multiple generations, or even if it has a new function in Xcel’s future corporate identity, he's going to have value.
Munsell
I guess your research sort of doesn't get quite into the present day, but for my understanding Reddy Kilowatt is not really used much today. It was used by a utility in Barbados and an Ecuadorian soccer club more recently, but from your understanding do you know why he stopped being used?
Thompson
Well, I'm not sure that he stopped being used. I have seen the return of Reddy Kilowatt as a consumer figure and as a licensed product that appears on T-shirts and stickers. Amazon has been selling quite a lot of Reddy Kilowatt products. So it's possible that Xcel Energy that owns the trademark sees the value of the product for a new market, which is the nostalgic market, where you can sell a cartoon character itself.
Munsell: I do think that with the emergence of heat pumps, and induction stoves, there is a push toward home electrification and moving away from fossil fuels in your home. I wonder if that’s an opportunity for a reemergence of Reddy?
Thompson
Yeah, it could be an opportunity for them to repurpose the trademark.
Munsell
Is there anything else you wanted to add about your research into Reddy?
Thompson
I thought it was interesting, the blend that Reddy Kilowatt had of both the impersonal and the personal. On the one hand, we've mostly been talking about it as this cute cartoony character of appeal and personality. But on the other hand, he represents an abstract concept, which is almost robotic. He was literally a robot as part of his marketing. This concept of the kilowatt as one and a half horsepower was part of this wider discursive emergence in the ‘20s that electricity was both a servant, as an anthropomorphized figure, and an abstraction that is there at the flick of a switch.
And in their marketing, they used imagery that of course would never be used today. The association of kilowatt as both a “coolie” – which was the specific language used – and a slave.
So this kind of racist imagery is interesting because it gets to the roots of this idea of the dehumanized, depersonalized aspects of Reddy Kilowatt – that electricity represented by using this imagery, and they had little pictures of kilowatt, which were described as a slave or a “coolie” to explain that, basically, this was free labor and unlimited labor. So obviously addressed to an implicitly white consumer. [The idea that] racial imagery of course affected all kinds of aspects of American advertising is well known to scholars in this field and often played on imagery of blackness or whiteness, in the case of soap advertising, for example, but Reddy Kilowatt in particular is this machinic identity.
And who knows, maybe that'll come back again in the future, because machines are so much more part of our lives now, as compared to 1926 or the mid century with computers and artificial intelligence.

SoftBank’s error and Nvidia’s scandal suggest data centers may have already peaked as an economic and energy trend.
This is Heatmap Daily, a weekday digest written by our executive editor. Subscribe here.
Covering energy and climate change sometimes means seeing certain stories in a different light than others. And a particularly vivid hue illuminated The Wall Street Journal’s report today that the Japanese conglomerate SoftBank Group is taking a $3.7 billion loss on several gigawatts’ worth of natural gas turbines.
For the Journal, the big news is that SoftBank and its billionaire founder, Masayoshi Son, are failing to capitalize on the artificial intelligence boom. But at Heatmap, we’re thinking about the turbines.
The data center boom and the return of electricity load growth has depleted the world’s supply of natural gas turbines. SoftBank had purchased reservations for about 13 gigawatts of turbines, according to the Journal. That’s a staggering amount of electricity — it could meet New York City’s maximum power draw on the hottest part of a summer’s day. The conglomerate now seems set to dump reservations for about four gigawatts’ worth. Keeping a reservation, it turns out, really is harder than making it.
Most of those rotors were reportedly from GE Vernova, one of the world’s largest producers of gas turbines. GE Vernova’s order list for gas turbines has been filled for nearly two years and the waiting list now stretches into 2031. That has led data center developers, hungry to get power as soon as possible, to reach for ever dirtier forms of electricity generation, including diesel generators and even old jet engines.
On that front, SoftBank’s failure to sell the turbines to a higher bidder suggests (albeit weakly) that demand for energy-producing assets might not be as strong as the AI boom’s backers once thought. SoftBank was already set to send about 9 gigawatts of turbines to the enormous Trump-backed OpenAI data center in Pike County, Ohio. The roughly remaining four gigawatts will be released back their manufacturers. (One thing this news can’t quite tell us, alas, is what type of turbine set-up will be used in the Pike County facility, which will be the world’s largest gas-fired power plant if it is build to completion. Recent public filings have suggested the facility isn’t planning on using any turbines in the more efficient combined-cycle configuration, which would mean the plant’s carbon intensity will be worse than most other new natural gas plants. But we’d love to hear any tips on this front.)
To zoom out for a second, I’m struck by how the AI bubble has been replaced by an AI muddle. As I wrote this, news emerged that Nvidia is preparing to fire its CEO, Jensen Huang, for his affair with a Chinese woman who is alleged to be a spy. (He had at least one more affair with another Nvidia executive, according to The New York Times.) Under Huang’s leadership, Nvidia has invested in a sprawling and sometimes circular network of energy-related companies, including Emerald AI, a startup that helps data centers flex their electricity consumption, and Redwood Materials, a battery recycler and producer led by the former Tesla executive J.B. Straubel. Huang has used Nvidia’s enormous balance sheet to buy down the risk of other AI and AI-related companies, propelling the overall AI trade to become the biggest story in American markets.
Now that balance sheet is in peril: Nvidia’s stock is already down 11% over the past five days, and it has fallen another 8% in after-hours trading since news broke of Huang’s ouster. If the chip designer’s financial network began to fray — or even if the next CEO had a lower risk appetite than Huang — then its demise could impact a much larger set of firms.
Even before the Huang scandal broke, companies at the center of the AI trade were showing signs of weakness. Alphabet, Meta, and Microsoft are all down on the month. Nvidia was already lagging by about 10% on the month before its hebdomas horribilis began, too. The memory and chip makers Micron and Applied Materials are both down more than 25% in about the same period, and GE Vernova and Oklo have fallen nearly 20%. Although the data center company Coreweave rebounded on an earnings beat today, it’s still down 24% on the month and nearly 50% since May.
The market rout isn’t total — Anthropic seems likely to enjoy one of the largest IPOs ever in the next week (although perhaps not with quite as large a valuation as its investors once imagined). And the underlying technology of AI seems to be getting worryingly better all the time. But even though the politics of data centers and AI seem set to dominate the new Washington, I’m wondering if data centers as a mainstream economic trend might have already peaked. Americans voted for a more subdued AI boom in the midterms. Now it seems like they might get it ahead of schedule.
Lunar Energy’s latest AI-powered system aims to integrate EVs into the automated demand response mix.
In theory, it’s straightforward to assemble the smart energy home: Solar panels, home backup batteries, and electric vehicles, plus smart thermostats, heat pumps, and water heaters — all the individual pieces can be had for the homeowner who can afford the up-front cost. The challenge is getting all those pieces to talk to one another.
Bay Area-based Lunar Energy is one of the tech firms that’s been trying to crack this problem. Today, it announced an upgraded version of its artificial intelligence-powered home energy control system, which not only integrates all those separate systems but also responds tactically to energy markets. CEO Kunal Girotra told me Lunar AI saves its users money by monitoring their home 24/7 and making decisions to charge, not to charge, or discharge so that they save the most money.
“Utilities are all moving to almost-real-time changes of rates,” he said. “You need software to handle that for you. I think that the race is on for who has the best AI machine learning algorithms to save the most amount of money. And so far, we seem to have a head start.”
Lunar’s first-generation system focused on generation, storage, and control. In other words, it connected elements like a home’s rooftop solar panels with the backup battery the residents might keep in the garage, using the AI to decide when to meet the home’s real-time energy needs with solar versus grid energy versus stored power. What it didn’t have was the ability to work with electric vehicles to manage charging and use the car’s battery as a bonus source of energy.
To fix this, Lunar has built its own bidirectional EV charger — one that can charge up the battery or discharge the car’s battery for a secondary use, like backing up the home’s power supply. Girotra, formerly the head of Tesla Energy, told me the problem with that functionality to this point has been the connection point between the car and the home electrical system. Carmakers and other companies in the space didn’t have the deep experience with electrical certifications to make the process seamless, he tells me. That led to setups like the original Ford Charge Station Pro, which required several different wall-mounted electrical boxes to connect the F-150 Lightning EV to the home.
Lunar’s charger is built to connect to its customers’ existing home Lunar energy system, which includes a microgrid interconnect device they call Lunar Bridge that islands the home in case of a power outage on the grid. In that way, the power stored in the EV battery is ready to back up the home in case of a blackout without any additional work — or to be optimized as part of a fully smart home that’s making money as part of a virtual power plant.
The company’s setup allows for another fun feature: “slow” charging that’s not slow at all, but actually two or three times as fast as the Level 2 charging most EV owners use to recharge their batteries overnight. Electric cars in the U.S. can typically take on only about 11 kilowatts of AC power from one’s home because of the limitations of their on-board hardware. Because Lunar’s system is fully DC, however, Girotra said the company decided to build a DC home charger, one that — like a Tesla Supercharger or other DC fast chargers out in the world — isn’t limited by that power cap. Lunar said it could use a combination of power from the grid, home solar, or home batteries to charge an EV at up to 25 kilowatts. That’s enough to recharge an EV in three to four hours rather than six to eight.
“If the standards get high, and if everybody sees cars can get charged in three hours, then all of a sudden people are like, ‘Wow, this is how I want it,’” he said. “Especially for 25% of the users who are like me, who always are running low on charge and they don’t mind a boost every now and then.”
Some of the other improvements in the second-gen system are more incremental. An inverter that’s 40% more powerful helps Lunar get its system up to enterprise scale. That’s crucial, as the world moves toward a place where more homes and businesses employ battery backup systems. Lunar’s new batteries come in modular 5 kilowatt-hour blocks ranging from 10 kilowatt-hours to 30 kilowatt-hours in a single unit and scale up to 300 kilowatt-hours for home or small commercial use; there’s also new pad-mounted configurations with capacity up to 1 megawatt-hour.
Batteries, though, are the simple part. Everyone from EV makers like Rivian to utilities like Octopus Energy is racing to make a person’s or a business’s batteries and solar panels and electric cars work for them, using the power of AI to account for moment-to-moment changes in energy prices and supply. Lunar’s new tech makes the case that the most important element is a single brain to integrate every last smart, electrified thing in your house.
The fundraise comes on the heels of a $50 million grant from the Department of Energy.
Almost all lithium-ion batteries on the market rely on graphite for their anodes, more than 90% of which is processed in China. That concentration has created a chokepoint in the Pentagon’s supply chain as the military increasingly turns to batteries to help its transportation network operate more quietly and reduce reliance on complex refueling logistics.
So when Congress passed the latest National Defense Authorization Act at the end of 2025, barring Chinese-linked battery materials from military use starting in 2028, Coreshell saw an opening. While the California-based silicon-anode battery startup had previously focused on automakers as its beachhead customers, it’s now shipping its first battery cells to the military for use on Navy ships and Army ground vehicles. On Wednesday, Coreshell announced a $30 million Series B to scale up manufacturing operations to meet the needs of this growing customer base.
“We’re entering a new stage where we’re no longer, I would say, demand limited,” Coreshell’s CEO Jonathan Tan told me. “This year we’ve had to put on second and third shifts, work nights and weekends, just to get the product out the door.”
Coreshell sets itself apart by going a step further than the NDAA requires. The law doesn’t make suppliers trace battery materials all the way back to the mine, which would be exceedingly difficult given China’s dominance across the battery supply chain. But Coreshell has nevertheless eliminated Chinese sourcing from its anodes by replacing graphite with silicon mined and refined in the U.S. by Ferroglobe, one of its Series A investors.
Ferroglobe and global investment firm Access Industries led the latest round, with defense contractor ADS also joining as a new strategic investor. The financing comes on the heels of a $50 million Department of Energy grant that Coreshell secured in August as part of a program to strengthen the domestic battery supply chain. That funding will support the company’s first commercial-scale facility, a 2-gigawatt-hour factory.
That’s about 20 times the size of the 100-ish-megawatt-hour plant the startup had originally envisioned, as the DOE grant has allowed Coreshell to “expand much further than we were originally expecting,” according to Tan. The company is now evaluating several potential U.S. sites and expects to announce its selection early next year. For now, it relies on unnamed contract manufactures, along with its small pilot line in San Leandro, to produce its cells. But once the gigafactory gets up and running, the startup plans to bring electrode production in house by 2028, followed by full cell assembly in 2029.
Building this plant will ultimately require significant additional capital. But Tan believes this latest vote of confidence from the federal government will help Coreshell to diversify its capital stack as it continues to fundraise. “That’s one of the great things about having such a notable DOE award is that it also allows us to attract multiple forms of capital,” he told me.
Silicon has long been recognized as a promising alternative material for battery anodes, as it can store far more energy than graphite. The catch is that it tends to swell during charging, causing it to break down quickly and ultimately leading to a much shorter cycle life. Coreshell says it’s extended its anode’s lifespan by giving it a proprietary coating, which Tan told me back in April essentially means “painting the inside of your battery” with an ultra-thin protective layer.
Other companies, such as Sila Nanotechnologies and Group14 Technologies, are also working to commercialize silicon anodes. But Coreshell says many of its competitors rely on more highly engineered, expensive forms of silicon, such as silane gas. By contrast, Coreshell uses metallurgical silicon, a cheap, raw commodity already widely used in aluminum alloys. That, Tan argues, gives the company a cost advantage not only over its competitors, but potentially Chinese graphite too.
Coreshell hasn’t yet demonstrated that its cells can meet the performance demands of the automotive industry, however. When the company raised its Series A in early 2025, it said it expected its automotive cells to exceed 1,000 charge cycles while retaining 80% of their original capacity. But Tan told me many defense applications don’t require such demanding performance targets, as Navy ships and ground vehicles are “not intending to have as many miles or missions or use cases on that same battery” as a consumer EV would.
That doesn’t mean the company is abandoning its automotive ambitions. As Tan pointed out, electric vehicles remain by far the largest source of global and domestic battery demand. “It’s natural for us to obviously utilize the security supply chain first,” he told me. “That allowed us to really get to commercialization, revenue, and production faster, because automotive qualification is this longer journey. But ultimately, we want to do both of those and more.”
