Elon Musk and Warren Buffett Squabble Over Solar In Nevada
Warren Buffett’s Berkshire Hathaway owns NV Energy, the largest utility company in Nevada. NV Energy has recently pressured the Nevada PUC to slash the amount it must pay residential solar customers for electricity from rooftop solar arrays. Elon Musk is not happy.
Warren Buffett’s company Berkshire Hathaway owns NV Energy, Nevada’s largest electric utility. Part of Tesla Motors’ agreement with the State of Nevada regarding the Gigafactory is a provision that guarantees the factory to receive discounted electricity rates for 8 years. However that discount will result in a $1.50 per year increase to existing NV Energy customers, according to the Las Vegas Sun.
Elon Musk has a major role in SolarCity, the rooftop solar company that specializes in helping residential customers obtain rooftop solar systems for their homes. In Nevada, those homeowners were able to sell any excess electricity back to NV Energy through a process known as net metering. The reimbursement rate was set at 11 cents per kilowatt. That extra money helped fuel a boom in residential rooftop solar with SolarCity leading the way.
But recently, under heavy pressure from NV Energy, the Nevada Public Utilities commission slashed the rate to just 2.6 cents per kilowatt. The rooftop solar companies screamed that the move would eviscerate the residential solar industry in the state. SolarCity shut down its operation in Nevada and laid off hundreds of employees.
Warren Buffett told CNBC on Monday that it is ridiculous for NV Energy to pay rooftop solar customers 11 cents per kilowatt when the company’s base cost of electricity from conventional operations is just 5 cents per kilowatt. He says it is unfair for 1,000,000 customers who don’t have rooftop solar to subsidize the 17,000 or so who do. He says Elon Musk has called and spoken to him about the situation.
“He was unhappy,” Buffett said of Musk. Then he added, “He’s being subsidized with his battery plant big time.” Is that really true? The battery factory Buffett is referring to is the Tesla Gigafactory, which has been designed from the start to be net zero. That means it will generate more electricity every year than it uses. Net zero does not mean it will never draw power from the electrical grid. It means it will put more back into the grid than it uses over the course of a year. There is no information available on how the new rules from the Nevada Public Utilities commission may impact Tesla.

In order to qualify for the subsidies, Tesla must prove it is hiring a certain percentage of Nevada natives to build and operate the Gigafactory. Tesla has agreed to provide money and other resources to expand schools, police, and fire services in the area. It is also acting as a magnet for other industries to move to what was previously an undeveloped desert.
Musk always likes to remind people that the $1.3 billion Tesla is receiving in incentives amount to only a small discount compared to the size of the economic benefits the project is conferring on the area. “It makes sense that if something is the biggest thing on Earth, it’s probably going to have incentives that are big in the absolute, but small in relative terms,” Musk says
Warren Buffett likes to say that Berkshire Hathaway is strongly committed to reducing global carbon emissions. But he, like the Koch Brothers, is heavily invested in fossil fuels. According to ThinkProgress, he wrote in his annual letter to investors recently, “Last year, BHE [Berkshire Hathaway Energy] made major commitments to the future development of renewables in support of the Paris Climate Change Conference.”
That may be true, but last year it also nearly doubled its position in Phillips 66 and boosted its investment in Suncor position by nearly seven million shares to 30 million shares, an investment now worth approximately $1.1 billion. Suncor is the Canadian company that seeks to develop the Alberta tar sands, the dirtiest source of petroleum on the planet.
Buffett may be one of the smartest investors in the history of the planet, but he is no leader on climate change issues the way Musk is. His letter to investors had this paragraph: "As a citizen, you may understandably find climate change keeping you up nights. As a homeowner in a low-lying area, you may wish to consider moving. But when you are thinking only as a shareholder of a major insurer, climate change should not be on your list of worries."
ThinkProgress labels coastal flooding as a potential trillion dollar liability. Berkshire Hathaway is one of the largest companies in flood insurance and therefore has a huge potential risk from rising sea levels.

Tesla has opened its northernmost Supercharger in Fairbanks, Alaska, with eight V4 stalls located in one of the most frigid cities in the U.S.
Located just 196 miles from the Arctic Circle, Fairbanks’s average temperature for the week was around -12 degrees Fahrenheit. However, there are plenty of Tesla owners in Alaska who have been waiting for more charging options out in public.
There are only 36 total Supercharger stalls in Alaska, despite being the largest state in the U.S.
Eight Superchargers were added to Fairbanks, which will eventually be a 48-stall station. Tesla announced its activation today:

The base price per kWh is $0.43 at the Fairbanks Supercharger. Thanks to its V4 capabilities, it can charge at speeds up to 325 kW.
Despite being the northernmost Supercharger in North America, it is not even in the Top 5 northernmost Superchargers globally, because Alaska is south of Norway. The northernmost Supercharger is in Honningsvåg, Norway. All of the Top 5 are in the Scandanavian country.
Tesla’s Supercharger expansion in 2025 has been impressive, and although it experienced some early-quarter slowdowns due to V3-to-V4 hardware transitions, it has been the company’s strongest year for deployments.
🚨🚨 Tesla Supercharging had a HUGE year, and they deserve to be recognized.

Through the three quarters of 2025, the company has added 7,753 stations and 73,817 stalls across the world, a 16 percent increase in stations and an 18 percent increase in stalls compared to last year.
Tesla is on track to add over 12,000 stalls for the full year, achieving an average of one new stall every hour, an impressive statistic.
Recently, the company wrapped up construction at its Supercharger Oasis in Lost Hills, California, a 168-stall Supercharger that Tesla Solar Panels completely power. It is the largest Supercharger in the world.

Tesla shocks with latest Robotaxi testing move
Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.
Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.
However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:
🚨 Tesla is using Model S vehicles fitted with LiDAR rigs to validate FSD and Robotaxi, differing from the Model Ys that it uses typically

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”
It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.
Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.
Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”
However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.
Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla
Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.
Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.
Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.
CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.
He said:
“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”
At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:
“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”
The Hardware
Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.
It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.
Meet the Rivian Autonomy Processor.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.
ACM3 specs include:
- 1600 sparse INT8 TOPS (Trillion Operations Per Second).
- The processing power of 5 billion pixels per second.
- RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
- RAP1 is enabled by an in-house developed AI compiler and platform software
As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”
More Details
Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.
More than any other feature, our owners have asked for more hands-free miles.
With Universal Hands-Free, you can now enjoy hands-free assisted driving on any road with clearly defined lanes. That’s roughly 3.5 million miles in the U.S. and Canada.
Look for it in our next… pic.twitter.com/ZFhwVzvt6b

Rivian will now join the competitive ranks with Tesla, Waymo, Zoox, and others, who are all in the race for autonomy.
