Tesla and other EVs’ potential to reduce emissions is widely underestimated: study

There are a lot of misconceptions about electric vehicles, but arguably the most prominent is the argument that EVs pollute more than their internal combustion engine-powered counterparts. Despite being debunked over and over again by people like Tesla CEO Elon Musk and organizations like Bloomberg NEF, the “long tailpipe” myth has remained incredibly persistent.

A recent study from electric mobility expert Auke Hoekstra has concluded that electric vehicles actually have the potential to be far cleaner than expected, especially since battery manufacturing and the power grid will likely not remain static. As the adoption of more efficiencies in battery manufacturing are rolled out and as more and more energy is gathered through renewable sources, the greenhouse gas emissions of electric cars like the Tesla Model 3 will see a dramatic reduction.

The findings of Hoekstra et al. stand in stark contrast to the conclusions of a study published by scientists Christoph Buchal, Hans-Dieter Karl and Hans-Werner Sinn earlier this year, who claimed that a Tesla Model 3 pollutes more than a Mercedes-Benz C 220 d due to the greenhouse gas emissions involved in the production of the electric car’s batteries. This conclusion, according to Hoekstra, has several critical mistakes.

For one, researchers such as Buchal et al. tend to overestimate the emissions produced in the battery manufacturing process. Hoekstra noted that around 65 kg of greenhouse gas emissions is emitted for every kWh of battery produced, which includes extracting and refining raw materials and actually producing the battery cells themselves. Buchal’s study estimated that the Model 3 emits 145–195 kg/kWh for its battery production, which does not take into account new chemistries that are adopted for battery production, or improvements in the cell manufacturing process.

The lifetime of batteries is also grossly underestimated in studies that allege EVs pollute more (or marginally less) than gas cars. In Buchal et al.’s case, for example, the scientists estimated that the Model 3’s batteries would only last 150,000 km (around 93,000 miles) before they are scrapped. This is a miscalculation, considering that current-generation batteries are estimated to last at least 1,500 to 3,000 cycles before they lose 20% of their capacity. For a vehicle like a Tesla Model 3 with Dual Motor AWD, which has a range of 310 miles, this would give the car around 747,000 km (about 464,000 miles) on the low end (1500 cycles) before their batteries would need replacing. And even after this, the batteries are recycled, not discarded, as noted by Elon Musk.

Perhaps the most notable miscalculation from EV critics is that many fail to account for the fact that electricity itself is getting greener with the adoption of renewable energy solutions. Battery-electric vehicles in some areas of the globe might be driving on power generated from coal today, but that will not always be the case. If an EV is driven on renewable energy sources, Hoekstra estimates that the battery-powered vehicles’ emissions would drop by a factor of 10. And that’s computing it using current-generation renewable technology.

The struggle for the future’s preferred form of propulsion will continue to be waged between batteries/electric motors and fossil fuels/internal combustion engine. Yet, it is essential to note that the internal combustion engine is already a mature technology that has likely reached its peak. Battery-powered cars, on the other hand, are only getting started. Heralded by the Model 3, the advent of disruptive vehicles like the new Tesla Roadster, the Rivian R1T pickup, or even the Porsche Taycan could ultimately seal the deal on electricity being the preferred source of propulsion in the years to come.

Tesla Robotaxi has already surpassed Waymo in one extremely important key metric: size of service area.

Tesla just expanded its service area in Austin on Monday morning, pushing the boundaries of its Robotaxi fleet in an interesting fashion with new capabilities to the north. Yes, we know what it looks like:

The expansion doubled Tesla Robotaxi’s potential travel locations, which now include the University of Texas at Austin, a school with over 53,000 students.

The doubling of the service area by Tesla has already made its travel area larger than Waymo’s, which launched driverless rides in October 2024. It became available to the public in March 2025.

According to Grok, the AI agent on X, Tesla Robotaxi’s current service area spans 42 square miles, which is five square miles larger than Waymo’s service area of 37 square miles.

The service area is one of the most important metrics in determining how much progress a self-driving ride-hailing service is making. Safety is the priority of any company operating a ride-hailing network, especially ones that are making it a point to use autonomy to deploy it.

However, these companies are essentially racing for a larger piece of the city or cities they are in. Waymo has expanded to several different regions around the United States, including Arizona and Los Angeles.

Tesla is attempting to do the same in the coming months as it has already filed paperwork in both California and Arizona to deploy its Robotaxi fleet in states across the U.S.

As the platform continues to show more prowess and accuracy in its operation, Tesla will begin to expand to new areas, eventually aiming for a global rollout of its self-driving service.

The first of over 300 Tesla Megapacks have arrived to the site of a massive battery energy storage system (BESS) being built in Australia, dubbed the Stanwell Battery Project after a coal plant it’s set to replace.

In a press release last week, the Stanwell Battery Project announced that the first Tesla Megapack 2XL units had arrived to the site, which is located outside of Rockhampton in Queensland, Australia. The project will eventually feature 324 Megapack units, set to arrive in the coming months, in order to support the 300MW/1,200MWh battery project.

“The Stanwell Battery is part of the diversification of our portfolio, to include cleaner and more flexible energy solutions,” said Angie Zahra, Stanwell Central Generation General Manager. “It is just one part of the 800 MW of battery energy storage capacity we have in our pipeline.

“Capable of discharging 300 MW of energy for up to four hours (1,200 MWh), our mega battery will be one of the largest in Queensland.”

The state is working with government-owned company Yurika to facilitate construction, and the process is expected to create roughly 80 jobs. The project is expected to come fully online in May 2027, with initial commissioning of the Megapacks aiming for November 2025.

The Stanwell Battery is set to replace the nearby Stanwell coal generation plant, which the government is planning to wind down starting in 2026 as part of efforts to reach an 80 percent renewable energy generation ratio by 2035. Meanwhile, the government is also set to begin winding down the Tarong and Callide coal plants, while several other Megapack projects are being built or coming online. o ya

Tesla currently has two Megapack production facilities, located in Lathrop, California, in the U.S. and another that came online earlier this year in Shanghai, China. The Shanghai Megafactory shipped its first units to Australia in March, while both factories are expected to be capable of producing 10,000 Megapack units per year upon reaching volume production.

Tesla has finally completed the construction of its highly anticipated Diner, Drive-in, and Supercharger in Los Angeles, and recent photos of the interior’s “retro-futuristic” style are making their way around the internet.

X user Brad Goldberg shared photos from the Tesla Diner site last Tuesday, depicting some of the Supercharger stalls, indoor and outdoor seating areas, multiple neon lights, and even an Optimus robot. Goldberg also noted that there had been a “flurry of activity on site” while he was snapping the photos last week, suggesting that the restaurant location could be getting close to opening.

The Tesla Diner also served one of its first internal customers in the past few days, as Elon Musk posted on X on early Monday morning that he had just finished up eating a meal at the site:

I just had dinner at the retro-futuristic Tesla diner and Supercharger.

Team did great work making it one of the coolest spots in LA!

The photos also show that the site is pretty much done, with some of them even showing vehicles charging at the charging stalls.

When will the Tesla Diner open to external customers?

While it’s still not open to external customers yet, the news again suggests that the company could be close to an official opening date. Tesla first broke ground on the Diner in September 2023, after receiving a wave of building permit approvals throughout that year. Teslarati also covered much of the construction progress throughout last year, including when crews installed the first and second drive-in screens.

Located at 7001 West Santa Monica Boulevard, the idea was first discussed in 2018 by Musk and a few others on Twitter, featuring 1950s rock and roll, waiters on roller skates, and drive-in movie theater screens playing clips from some of history’s best movies. Notably, the photos of the front doors also show that the site will be open 24 hours a day, 7 days a week, whenever it does end up opening.
