Future Teslas Could Come “Energy Included”
Future Teslas could come “energy included”, no matter how much you drive, for the life of the car. Crazy as it sounds, Tesla can actually make money giving Tesla owners free energy at home not just at Superchargers. Key components are already on the road or under development at Tesla. So, how would this work, when will it happen and what does it mean for Tesla owners and Tesla investors?
How it works
Tesla can provide grid regulation and stabilization services worth as much as the energy used for charging, or more, by centrally controlling the time and rate at which Tesla cars are charged. Embedding a modest up-front cost increment into the price of a special Tesla charging connector, pays energy cost in excess of earnings from grid regulation and stabilization as an “annuity”, and can leave a lot of money in Tesla’s pocket, too. This model is similar to Tesla’s Supercharger business – there is a detailed analysis of Tesla’s Supercharger business I did a while back on Seeking Alpha.
Owners will handle charging differently. Instead of setting charging current, normal or range charging, and (optionally) the charging start time, the owner will instead set a time for charging to be completed and whether a normal or range charge is needed by that time. The Tesla charging control center will then match the charging rate of each Tesla car using over-the-air communication links to earn grid regulation fees and capture the best electric rates while making sure each car is recharged when the owner needs to drive off.
Central Control of Charging Rate Provides Grid Stabilization
Your garage charging connector will be fed from a separate meter and the connector will “identify itself” to the car to enable Tesla controlled charging.
Two things make this scheme economically viable. There is flexibility in exactly when your Tesla charges because most days the charging time is much less than the time your car spends plugged in overnight. This flexibility lets charging be “timed” to help regulate the grid. When wind generation surges due to gusts, or when system load suddenly drops, chargers can be switched on to “swallow” the power surge. The grid system operator, working through the Tesla charging control center can rapidly adjust the charging load to help stabilize the grid.
Rapid adjustment of loads on the grid is valuable because it allows the grid to use more wind power with less fossil generation online as “spinning reserve”. When a large number of car chargers quickly switch on to “swallow” a surge in wind generated power, the value of the “regulation down” can actually be greater than that of the energy used by the chargers. At these times, the system operator will actually pay to have cars charge!
When will free home charging happen?
The answer is, we aren’t there yet. Utilities are only beginning to wrestle with what happens when large amounts of battery storage get connected to the grid. This turns out to be quite complicated. This Sierra Club Energy-Storage Cost-Effectiveness paper offers a summary of the results of several grid storage studies done for the California Independent System Operator (CAISO). At this point we can’t do a specific financial model because technologies, rate structures and even how grid regulation will work with attached storage have not been set.
There are also, at this point, too few Tesla cars on the road to make their charging a significant source of grid regulation. And so far, there is no central control system in place to coordinate the charging of Tesla cars. But times are changing.
CAISO now operates a unified energy imbalance market (EIM) across all or parts of seven states (CA, ID, NV, OR, UT, WA, WY). Within a few years one can imagine upwards of half a million Teslas registered in these states. When these cars are (mostly) plugged in for charging at night, they together represent several giga-watts of load that can be switched on or off in seconds, using the central charging control scheme. That’s a lot of wind regulation capability that requires almost no additional capital investment. It just might get us “free” energy to charge Tesla cars in their owner’s garages.
Status: Where are we on the path to free energy?
Tesla is doing a lot more with grid connected storage and grid regulation than many Tesla owners, and even many Tesla investors realize. In May of this year, J.B. Straubel, Tesla’s Chief Technology Officer made the keynote presentation at Silicon Valley/ SEEDZ Energy Storage Symposium. He discussed a surprising array of Tesla storage products already being made and installed in grid applications, from small residential storage systems being rolled out by SolarCity to large industrial units delivering hundreds of kilowatts. Video of JB’s presentation is available on YouTube here.
A lot of the hardware needed for central charging control of Tesla cars is already part of every Tesla. Every Model S already has a big battery, of course. And high power 10kW or 20kW chargers that are controlled through the touchscreen and the car’s computer. Every Tesla car has a broadband communication link to Tesla company computers that is used to download software updates. These links are available to control charging on a car-by-car basis. Tesla already makes a high power wall connector (HPWC) that can be installed with connection through a standard utility meter. Buying and installing one of these will probably be a requirement to get “free” charging at home.
The only part of the remote charging scheme that isn’t online today is the central control system for “aggregating” car charging so it can be controlled by the grid system operator. Everything else needed to implement aggregated charge control for Tesla cars is either already in production at Tesla or available off the shelf as commercial products or communication services.
In his talk, JB describes aggregation of many residential storage systems to allow the grid operator to use that distributed resource in much the same way aggregated car charging control might be used to stabilize and regulate the grid. At the end of his talk, there is a Q and A session. Someone asks what Tesla’s plans are for eventually implementing the aggregated control center JB described. His answer, “We are building it now.”
Should Tesla owners / investors care about this?
Probably, but some caution is warranted. Tesla owners already talk to their ICE driving friends about how much less electricity costs compared to gasoline or diesel fuel. If in the future all Tesla charging is free, both at home and from Superchargers when traveling long distances, Tesla owners will be left with literally “nothing” to talk about – something their fossil fueled friends may (or may not) appreciate.
For Tesla investors, the prospect of making all the energy for Tesla cars free has some big implications. If the economics parallel those of the Supercharger business, Tesla could see very large additional profit (billions of dollars at least) for something that would require negligible new capital investment by Tesla.
There will be indirect benefits for Tesla, too. Already Tesla cars offer the advantage of much lower energy cost compared to ICE cars, and even hybrids. Free charging at home and at Superchargers would make Tesla cars energy cost even lower than other electric cars which get charged on the owner’s electric meter. While the absolute economic advantage of free charging, compared to other electric cars, will be modest, the emotional value of getting energy for free should never be underestimated as a competitive edge in the market place.
And of course there is the plain, simple novelty of offering a car that costs nothing to run. This is a feature no other car is likely to have, and which no other car (with the exception of soap box derby and solar-car competition cars) has had before. It is newsworthy, people will talk and write about it and it will produce a lot of buzz and free advertising for Tesla. Tesla investors need to be careful not to be overcome with hysteria as the shares go up, yet again.

Elon Musk and Tesla AI Director share insights after empty driver seat Robotaxi rides
The executives’ unoccupied tests hint at the rapid progress of Tesla’s unsupervised Robotaxi efforts.
Tesla CEO Elon Musk and AI Director Ashok Elluswamy celebrated Christmas Eve by sharing personal experiences with Robotaxi vehicles that had no safety monitor or occupant in the driver’s seat. Musk described the system’s “perfect driving” around Austin, while Elluswamy posted video from the back seat, calling it “an amazing experience.”

Elon and Ashok’s firsthand Robotaxi insights
Prior to Musk and the Tesla AI Director’s posts, sightings of unmanned Teslas navigating public roads were widely shared on social media. One such vehicle was spotted in Austin, Texas, which Elon Musk acknowleged by stating that “Testing is underway with no occupants in the car.”
Based on his Christmas Eve post, Musk seemed to have tested an unmanned Tesla himself. “A Tesla with no safety monitor in the car and me sitting in the passenger seat took me all around Austin on Sunday with perfect driving,” Musk wrote in his post.
Elluswamy responded with a 2-minute video showing himself in the rear of an unmanned Tesla. The video featured the vehicle’s empty front seats, as well as its smooth handling through real-world traffic. He captioned his video with the words, “It’s an amazing experience!”
Towards Unsupervised operations
During an xAI Hackathon earlier this month, Elon Musk mentioned that Tesla owed be removing Safety Monitors from its Robotaxis in Austin in just three weeks. “Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks,” he said. Musk echoed similar estimates at the 2025 Annual Shareholder Meeting and the Q3 2025 earnings call.
Considering the insights that were posted Musk and Elluswamy, it does appear that Tesla is working hard towards operating its Robotaxis with no safety monitors. This is quite impressive considering that the service was launched just earlier this year.

Starlink passes 9 million active customers just weeks after hitting 8 million
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
SpaceX’s Starlink satellite internet service has continued its rapid global expansion, surpassing 9 million active customers just weeks after crossing the 8 million mark.
The milestone highlights the accelerating growth of Starlink, which has now been adding over 20,000 new users per day.
9 million customers
In a post on X, SpaceX stated that Starlink now serves over 9 million active users across 155 countries, territories, and markets. The company reached 8 million customers in early November, meaning it added roughly 1 million subscribers in under seven weeks, or about 21,275 new users on average per day.
“Starlink is connecting more than 9M active customers with high-speed internet across 155 countries, territories, and many other markets,” Starlink wrote in a post on its official X account. SpaceX President Gwynne Shotwell also celebrated the milestone on X. “A huge thank you to all of our customers and congrats to the Starlink team for such an incredible product,” she wrote.
That growth rate reflects both rising demand for broadband in underserved regions and Starlink’s expanding satellite constellation, which now includes more than 9,000 low-Earth-orbit satellites designed to deliver high-speed, low-latency internet worldwide.
Starlink’s momentum
Starlink’s momentum has been building up. SpaceX reported 4.6 million Starlink customers in December 2024, followed by 7 million by August 2025, and 8 million customers in November. Independent data also suggests Starlink usage is rising sharply, with Cloudflare reporting that global web traffic from Starlink users more than doubled in 2025, as noted in an Insider report.
Starlink’s momentum is increasingly tied to SpaceX’s broader financial outlook. Elon Musk has said the satellite network is “by far” the company’s largest revenue driver, and reports suggest SpaceX may be positioning itself for an initial public offering as soon as next year, with valuations estimated as high as $1.5 trillion. Musk has also suggested in the past that Starlink could have its own IPO in the future.

NVIDIA Director of Robotics: Tesla FSD v14 is the first AI to pass the “Physical Turing Test”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine.
NVIDIA Director of Robotics Jim Fan has praised Tesla’s Full Self-Driving (Supervised) v14 as the first AI to pass what he described as a “Physical Turing Test.”
After testing FSD v14, Fan stated that his experience with FSD felt magical at first, but it soon started to feel like a routine. And just like smartphones today, removing it now would “actively hurt.”
Jim Fan’s hands-on FSD v14 impressions
Fan, a leading researcher in embodied AI who is currently solving Physical AI at NVIDIA and spearheading the company’s Project GR00T initiative, noted that he actually was late to the Tesla game. He was, however, one of the first to try out FSD v14.
“I was very late to own a Tesla but among the earliest to try out FSD v14. It’s perhaps the first time I experience an AI that passes the Physical Turing Test: after a long day at work, you press a button, lay back, and couldn’t tell if a neural net or a human drove you home,” Fan wrote in a post on X.
Fan added: “Despite knowing exactly how robot learning works, I still find it magical watching the steering wheel turn by itself. First it feels surreal, next it becomes routine. Then, like the smartphone, taking it away actively hurts. This is how humanity gets rewired and glued to god-like technologies.”
The Physical Turing Test
The original Turing Test was conceived by Alan Turing in 1950, and it was aimed at determining if a machine could exhibit behavior that is equivalent to or indistinguishable from a human. By focusing on text-based conversations, the original Turing Test set a high bar for natural language processing and machine learning.
This test has been passed by today’s large language models. However, the capability to converse in a humanlike manner is a completely different challenge from performing real-world problem-solving or physical interactions. Thus, Fan introduced the Physical Turing Test, which challenges AI systems to demonstrate intelligence through physical actions.
Based on Fan’s comments, Tesla has demonstrated these intelligent physical actions with FSD v14. Elon Musk agreed with the NVIDIA executive, stating in a post on X that with FSD v14, “you can sense the sentience maturing.” Musk also praised Tesla AI, calling it the best “real-world AI” today.
