Decarbonizing the Grids with Demand Response
By Karina Hershberg, PE
For most of human history, work and activity has been shaped by the sun. During the day, humans could farm, socialize, and build. At sunset, activity had to slow down, and shelter found. Energy was only used when energy was available, during daylight hours. We were leading Net Zero Carbon lives before it was cool.
By first harnessing biofuels and then fossil fuels, life got to expand beyond the confines of sunrise and sunset. Fossil fuels were an amazing portable form of super dense energy that transformed humanity’s path through history and paved the way to our modern lifestyle. Unfortunately, these fuels also have led us to the abyss of the climate crisis in which we currently find ourselves. The question now is whether we can reconcile the negative aspects of our relationship with energy while preserving the positive.
Enter the concept of grid-interactive flexible loads. It doesn’t roll off the tongue quite as easy as “solar” or “wind,” which is perhaps why it hasn’t received the same amount of attention in discussions of sustainability. Yet, a closer look at the plans for energy decarbonization shows flexible loads are just as important to the success of this planet-saving solution as its more famous renewable energy cousins.
The concept of flexible load is called by many names — demand response, peak shaving, grid-interactive efficient buildings, distributed energy resources, and the list goes on. But despite a cornucopia of buzzwords, these terms all describe the same vision of utilizing buildings and their systems to help grids.
Net Zero … What?
Grid-interactivity and flexible loads are in response to the limitations of onsite solar generation and even the aspirations of net zero energy. Net zero energy has been an important goal for the building sector to target, but it technically is not the same as truly being in sync with available energy resources. In many ways, it is a math problem you do at the end of the year to reconcile your annual usage with your annual generation, whereas total decarbonization means your load is served by renewable sources every minute of every hour of every day. So, while net zero energy is a critical step in the right direction, 24/7 emissions-free energy is ultimately where we need to land. If done correctly, it will be a return to a zero-carbon lifestyle, one aligned with the energy flows of nature, while still supporting the advances of modern society.

DIY Grid-Interactivity
One of the key solutions for returning to a system in balance with renewable resources is to reimagine buildings and homes as dynamic partners in these larger utility systems instead of simply passive users of the energy services. This more dynamic relationship is where grid-interactive, flexible loads come back into the picture.
Demand response programs come in all shapes and sizes, but to an average homeowner such as myself, they can look as simple as a text message like the one I received on June 22, 2020. It was the inaugural residential “Peak Time Rebate Event” for my utility, Portland General Electrical (PGE). My text message invited me to reduce my household electricity use the following day from 5pm–8pm. In exchange, I would receive an incentive based on my decreased usage.

As an electrical engineer at PAE with a passion and expertise for sustainability design and the future of energy, I was excited to participate in this program for the first time. Finally, a chance to make my home my own research project! Living in an older house without air-conditioning, my family was already in the habit of passive cooling techniques for the hot summer days- shades on the windows, avoid opening doors during the hottest parts of the day, and generally try not to add heat to the house. When the time came, 5 PM on June 23, we went around the house trimming our electric loads. It was as straightforward as shutting off lights, avoiding appliance cycles like laundry and dishes, and making simple no-cook egg salad sandwiches for dinner, which the kids reported was the best dinner they had ever had. My children’s questionable culinary preferences aside, it was a nice evening with relatively little impact to our typical routine.
The next day when my phone pinged with a text from PGE, I was excited to see the results of my efforts, but that excitement turned to confusion when I opened the message. I had saved just $.75 — reducing energy consumption from my typical 2.02 kWh to an unremarkable 1.27 kWh. I was deflated. In the coming days, I compared notes with fellow energy geek colleagues and discovered we all had a similar experience — little measurable individual impact from our supposedly critical behavior change. What was going on?
Power of the Collective
It turned out the key to our seeming failure was the scale of our view. When observed through the lens of an individual, the impact to behavior and usage was minimal. But as a collective, the story suddenly changed. After talking with experts at PGE, I learned that the voluntary collective reduction of households in PGE service areas reduced energy demand by 11 MW per event hour compared to expected demands. It put us right on the cusp of eliminating the need for a peak-time natural gas engine, one of the highest emission sources for electricity generation. This impressive system-level impact was created by a humble group of early program adopters with an average savings of just 0.12 kWh per participating household.
This is, in fact, exactly what load flexibility is trying to achieve. Collective actions made up of small individual changes are a key element of grid decarbonization and translate into system-wide emissions savings. In the most extreme cases, these small collective actions can potentially even avoid the more catastrophic situation of grid outages as recently seen around the country. The reason is that to support higher than usual energy demands, typically because of an extreme weather event, utilities have to activate their most carbon-intensive quick-response plants, so-called “peaker plants.” By strategically organizing collective action to reduce demands on the grid during these peak times, we are collectively able to have a greater emissions sum impact than might appear from its energy parts.

“AND” Not “OR”
This brings us to what is perhaps my favorite aspect of load flexibility. When discussing sustainability, we often run into conversations about responsibility and blame. We compare and contrast the agency individuals have in their daily lives with corporations and industries who closely influence consumer options. Within the community of people who recognize the need for decarbonization and care passionately about the broad adoption of sustainable practices, even we can fall into the trap of asking the wrong question: “Should the burden be on individuals to change their habits?,” OR “Should corporations and industries be held responsible for systemic change?” In asking the question in this way we are using the wrong conjunction (and perspective for a solution). In reality, individuals need to make conscious efforts to change AND corporations and industries need to change. Demand response programs are an intriguing example of these paired truths. Changes by the individual directly support changes in the system, and vice versa.
Decarbonization of the electricity sector is one of the most critical system changes needed to reach U.S. climate targets and participation in local demand response programs is one of the more powerful tools we have as individuals to support that transition. Conveniently, it is also one of the easiest. Program registration is usually through your local utility with no cost and perhaps even a small incentive. My local utility, PGE, has several incentives from peak rebate times to smart thermostat programs. Although equipment like smart thermostats and home batteries can make participation easier and increase the benefits, low tech options like light switches and no cook meals work just fine, too.

A New Energy Relationship
After a full year of participating in the PGE residential demand response program, my family has dialed in our electrical load reduction strategies. Perhaps more importantly, it has changed my mindset about how and when my home is using energy. As a certified energy geek, I’ve spent more hours than I can count poring over utility emissions profiles and pondering how buildings can more wisely tap into the flow of electrons. By better understanding where and how our electricity comes from, we can better design our buildings and optimize our usage patterns. Embracing the perspective that the solutions are an “and,” and not an “or,” will also allow us to reach an optimized grid-interactive state. But whether you chose the automated solutions or a more manual approach to embark on this path, take it from my kids – make sure to include egg salad sandwiches.

![This is it: the FIRST pure electric vehicle to wear a Lamborghini badge [video]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/09/lamborghini_pwc.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
True to Lamborghini’s legacy of speed and excess, the first battery-electric vehicle to wear the raging bull is also the fastest of its kind. Only this time, the badge isn’t on a car — it’s on a personal watercraft. Meet the all-new Seabob SE63 jet sled.
Co-developed with the Italian supercar brand, the Lamborghini-badged Seabob SE63 features a more powerful jet propulsion system than any of the company’s existing personal jet sleds, and is fitted with a carbon fiber motor shaft as a further nod to the Italian luxury brand’s high-performance heritage.
Here’s the surprising thing, though: the new Seabob SE63 isn’t inspired by a specific road-going Lamborghini. Instead, it gets its name from the Tecnomar for Lamborghini 63 sport yacht built by the Italian Sea Group shipyards.
Tecnomar for Lamborghini 63
Why, yes – I will take just about any excuse to post pictures of sexy Italian super yachts in bright, vibrant colors. Thanks for asking!
But we’re not here for superyachts. We’re here for super sleds, and German PWC specialist Cayago set out to make this one, “most powerful Seabob ever.” As such, the SE63 is designed to be grab-and-go personal jet sled that delivers significantly higher speeds than its Seabob stablemates. In fact, its makers say it’s fast enough to keep up with sharks and dolphins.
The riding experience is not just ‘a bit faster’, but thrillingly intense and unrestrained. Acceleration off the start line delivers an immediate adrenaline rush. Thrust, agility, top speed: everything is designed for maximum performance and pure emotion.
The new SE63 backs up those claims with a 6.3 kW (~8.5 hp) electric motor. And, while that hardly makes it a supercar, in the world of ePWCs, it’s enough to make the SE63 a monster. The SE63 also features a bigger, more energy-dense battery than other Seabobs, a combination good for up to 60 minutes of go-fast, water-based fun.
Seabob SE63 Lamborghini
The SE63 can recharge its batteries with a standard power outlet in just 1.5 hours, and be back on the water for even more fun in the sun.
The Seabob SE63 made its debut earlier this week at the Cannes Yachting Festival. Production is set to begin in early 2026, meaning you’ll be able to get yours just in time for the summer 2026 beach season. Prices have yet to be announced – but, like any Lamborghini product, if you have to ask you probably can’t afford it.
Check out the world premier of the Seabob SE63 for Automobili Lamborghini (the sled’s official name) in the video, below, then let us know what you think of the brand’s first BEV in the comments.

Tesla influencers tried Elon Musk’s coast-to-coast self-driving, crashed before 60 miles
A duo of Tesla shareholder-influencers tried to complete Elon Musk’s coast-to-coast self-driving ride that he claimed Tesla would be able to do in 2017 and they crashed before making it about 60 miles.
In 2016, Elon Musk infamously said that Tesla would complete a fully self-driving coast-to-coast drive between Los Angeles and New York by the end of 2017.
The idea was to livestream or film a full unedited drive coast-to-coast with the vehicle driving itself at all times.
We are in 2025 and Tesla never made that drive.
Despite the many missed autonomous driving goals, many Tesla shareholders believe that the company is on the verge of delivering unsupervised self-driving following the rollout of its ‘Robotaxi’ fleet in Austin, which requires supervision from Tesla employees inside the vehicles, and improvements to its “Full Self-Driving” (FSD) systems inside consumer vehicles, which is still only a level 2 driver assist system that requires driver attention at all times as per Tesla.
Two of these Tesla shareholders and online influencers attempted to undertake a coast-to-coast drive between San Diego, CA, and Jacksonville, FL, in a Tesla Model Y equipped with the latest FSD software update.
They didn’t make it out of California without crashing into easily avoidable road debris that badly damaged the Tesla Model Y:
In the video, you can see that the driver doesn’t have his hands on the steering wheel. The passenger spots the debris way ahead of time. There was plenty of time to react, but the driver didn’t get his hands on the steering wheel until the last second.
In a follow-up video, the two Tesla influencers confirmed that the Model Y had a broken sway bar bracket and damaged suspension components. The vehicle is also throwing out a lot of warnings.
They made it about 2.5% of the planned trip on Tesla FSD v13.9 before crashing the vehicle.
Electrek’s Take
Tesla shareholders used to discuss this somewhat rationally back in the day, but now that Tesla’s EV business is in decline and the stock price depends entirely on the self-driving and robot promises, they no longer do.
I recall when Musk himself used to say that when you reach 99% self-driving, it is when the “march of the 9s” begins, and you must achieve 99.999999999% autonomy to have a truly useful self-driving system. He admitted that this is the most challenging part as the real-world is unpredictable and hard to simulate – throwing a lot of challenging scenario at you, such as debris on the road.
That’s where Tesla is right now. The hard part has just started. And there’s no telling how long it will take to get there. If someone is telling you that they know, they are lying. I don’t know. My best estimate is approximately 2-3 years and a new hardware suite.
However, competition, mainly Waymo, began its own “march of the 9s” about five years ago.
Tesla is still years behind, and something like this drive by these two Tesla influencers proves it.
I was actually in a similar accident in a Tesla Model 3 back in 2020. I rented a Model 3 on Turo for a trip to Las Vegas from Los Angeles.
I ended up driving over a blown-out truck tire in the middle of the road like this. I was Autopilot, but I don’t know if the car saw it. I definitely saw it, but it was a bit late as I was following a truck that just drove over it. I had probably less than 2 seconds to react. I applied the brakes, but my choices were driving into a ditch on the right or into a car in the left lane.
I managed to reduce the force of the impact with the braking, but the vehicle jumped a bit like in this video. There wasn’t really any damage to the front, but the bottom cover was flapping down. I taped it together at the next gas station and I was able to continue the trip without much issue.
However, after returning it to the Turo owner and having the suspension damage evaluated by Tesla, the repair job was estimated to be roughly $10,000. I wouldn’t be surprised if there’s a similar situation with this accident.

![Stellantis' new EV battery tech will put it ahead of – well, EVERYONE [video]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/09/Peugeot-E-3008_MAIN.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
Chrysler parent company Stellantis is calling its new, Intelligent Battery Integrated System (IBIS) system a breakthrough technology that will make future EVs lighter, more efficient, and quicker. Now, that “breakthrough” tech is now moving from concept to reality.
Co-developed with Saft, Sherpa Engineering, Université Paris-Saclay, and Institut Lafayette, Stellantis’ IBIS embeds the charger and inverter functions directly into the battery pack, an integration that results in reduced design complexity, interior space savings, and lifetime easier maintenance.
That improved efficiency carries on to the battery’s second life, too. IBIS facilitates the reuse of electric vehicle batteries in second-life battery energy storage systems (BESS) applications by reducing the need for extensive (and expensive) reconditioning.
“This project reflects our belief that simplification is innovation,” explains Ned Curic, Chief Engineering and Technology Officer at Stellantis. “By rethinking and simplifying the electric powertrain architecture, we are making it lighter, more efficient, and more cost-effective. These are the kinds of innovations that help us deliver better, more affordable EVs to our customers.”
Key IBIS benefits
- up to 10% energy efficiency improvement (WLTC cycle) and 15% power gain (172 kW vs. 150 kW) with the same battery size
- reduces vehicle weight by ~40 kg and frees up to 17 liters of volume, enabling better aerodynamics and design flexibility
- early results show a 15% reduction in charging time (e.g., from 7 to 6 hours on a 7 kW AC charger), along with 10% energy savings
- easier servicing and enhanced potential for second-life battery reuse in both automotive and stationary applications
Those benefits stem from the fact that EVs spend a lot of time and energy converting Alternating Current (AC) to Direct Current (DC) and back again with the – that’s true whether we’re talking about a L2 home charger or energy harvested from regenerative braking. Doing away with that process and the hardware that goes along with it could unlocks significant weight and efficiency benefits, with some estimates indicating that an IBIS car could weigh in at 40 kg less than a conventionally-equipped BEV, while still offering similar range and performance.
IBIS has been in development for several years, with the first proof-of-concept for stationary applications being built in 2022. The news today, however, is that the first fully functional, IBIS-equipped battery electric vehicle (BEV) is finally ready to hit the road.
Stellantis’ researchers installed the system under one of the company’s new Peugeot E-3008 electric crossovers. Guilt on the STLA Medium platform, the prototype follows years of design, modeling, and simulation by both Stellantis and Saft, and (if all goes well) could pave the way for the integration of IBIS technology into Stellantis’ electric and hybrid production vehicles by the end of this decade.
