A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Perhaps even more importantly, the study offers some quantifiable, granular data about how much electric vehicles are impacting emission rates in the here and now, not in the foreseeable future.

Not that these numbers will blow you away, mind you, but still, it’s good news.

Researchers from the University of California, Berkeley, found that between 2018 and 2022, CO2 emission from all sources (industries, homes, traffic) across the San Francisco Bay Area dropped around 1.8% per year – a difference the researchers attribute to widespread EV adoption in the area. For vehicle emission rates, those numbers dropped 2.6% annually. EVs made up nearly 40% of new auto registrations in San Jose and 34% in San Francisco last year.

“We show from atmospheric measurements that adoption of electric vehicles is working, that it’s having the intended effect on CO2 emissions,” said Ronald Cohen, a University of California Berkeley chemistry professor and senior author of the study. The study was published this week in the journal Environmental Science & Technology.

Researchers were able to track that data via a network of sensors around the Bay Area that monitor both CO2 and five critical air pollutants: carbon monoxide, nitrous oxides (NO and NO2), ozone, and particulates (PM 2.5).  

According to the research, by comparing the air pollution and CO2 data, the sensors help determine the emission source. The sensors are also unique in that they track CO2, which is not a pollutant regulated by the Clean Air Act and not picked up by Environmental Protection Agency sensors – the EPA of course does track CO2 but not as an air pollutant.

To get to their results, the researchers divided the emissions captured by the sensors into three categories: industry, such as refineries, which churn out a steady stream of emissions; seasonable varying emissions, like home heating and cooling; and traffic. After isolating the traffic emissions, researchers were able to link a dip traffic emissions to the rise in EVs, hybrids, and vehicles with better fuel efficiency.

While the sensors have been in place for more than a decade, it’s taken time to analyze the findings – and one could argue a while for EVs to reach a critical mass to trigger a difference. Looking at the data, the researchers also saw a drop in emissions during the pandemic.

The network of 50 sensors, set up in 2012 by Cohen, make up what’s called the Berkeley Environmental Air Quality & CO2 Network (BEACO2N), a system that has already been adopted by Providence, Rhode Island, and Glasgow, Scotland, to track their city air pollution. Around 70% of global CO2 emissions come from cities, yet few urban areas have granular data about where those emissions originate.

Another study last year, published by Keck School of Medicine at the University of Southern California, found similar results looking at emissions in California. That study tracked real-world pollution levels, electric car penetration, and emergency room visits across California between 2013 and 2019, and controlled against overall improvements in California air quality during the study period.

Electrek’s Take

Of course, any optimism is tempered by the reality that, to meet California and Bay Area carbon reduction goals, the yearly decrease needs to be much greater – twice what it is now. California has a goal to reach net-zero emissions by 2045, and Cohen says that we need emissions to drop 3.7% per year to reach that. Still, the onus isn’t only on traffic emissions. Home and industry emissions need to drop too, and making that happen requires policies.

Rivian (RIVN) EDV topped Ford to become America's best-selling electric van in 2024

Rivian (RIVN) had the best-selling electric van in the US last year, topping Ford for the title. The electric delivery van (EDV) is rolling out across the US through its partnership with Amazon, but Rivian is expanding with new customers.

Rivian EDV was the best-selling electric van in the US

With over 51,500 electric vehicles delivered in 2024, Rivian beat expectations. Although it was only slightly higher than the 50,122 delivered in 2023, things picked up in the second half of the year.

Rivian shut down its manufacturing plant in Normal, IL, last April to introduce new upgrades designed to cut costs and increase efficiency.

To make matters worse, Rivian had to temporarily pause electric van production last summer due to a part shortage.

After releasing fourth quarter and full-year 2024 delivery and production figures in early January, Rivian said, “The previously discussed shortage of a shared component on the R1 and RCV platforms is no longer a constraint.”

New Kelley Blue Book estimates show that Rivian outpaced Ford with America’s best-selling electric van in 2024.

Q4 2024 sales YOY Full-year 2024 sales YOY
Rivian EDV 4,397 +84.1% 13,423 +65.9%
Ford E-Transit 3,354 +56.5% 12,610 +64.4%

Rivian sold 13,423 electric vans in the US last year, up 67% from 2023. In comparison, Ford sold 12,610 E-Transit vans in the US in 2024. In the fourth quarter, Rivian outpaced Ford, with nearly 4,400 EDVs sold compared to 3,354 E-Transit sales.

The accomplishment comes despite Ford introducing the updated E-Transit last March with a bigger battery and faster charging. In October, the 2025 E-Transit hit the market with the same price as “comparable gas Transit models,” according to Ford, starting at $51,000.

Rivian has already secured a commitment from Amazon for up to 100,000 EDVs, but it also offers its commercial van (RCV), which is designed for other companies.

Over the past few weeks, Rivian electric vans with different brandings have been spotted testing, including logistics giant DHL.

As the Rivian scales production, its R1S electric SUV was also the tenth best-selling electric vehicle in the US last year.

Ultra-compact electric truck startup TELO partners with Aptera to integrate solar tech

A young EV startup called TELO Trucks has announced a partnership with solar EV developer Aptera to utilize the latter’s sustainable technology on its flagship vehicle, the MT1 compact pickup. Customers who pre-order a TELO electric truck will be able to choose from three Aptera solar panel configurations, helping boost the vehicle’s range while reducing grid dependency—as long as these BEVs get made.

TELO Trucks was founded by three gentlemen with various backgrounds in automotive technologies and creative design, including autonomy and ADAS at National Instruments and Roadster development during Tesla’s early days.

The startup launched its flagship MT1 compact electric pickup truck in June of 2023, which looks like an exciting exercise in space optimization. The MT1 features the bed capacity and crew cabin of a standard pickup truck within an impressively shortened vehicle length of 152 inches. As you can see in TELO’s image below, the MT1 offers the same interior cabin space and bed length as a Toyota Tacoma in the footprint of a MINI Cooper.

Since its unveiling, TELO says it has garnered over 4,550 pre-orders of the MT1, which is currently available in single and dual motors configurations, and the option for a long-range battery pack that promises a range upwards of 350 miles.

Soon, TELO will offer early customers additional options in its truck configurator – solar panels from Aptera Motors.

TELO to offer Aptera solar panels on its truck pre-orders

Aptera shared a blog post outlining the details of its new collaboration with TELO Trucks, which entails integrating solar panels of varying configurations into the MT1s that remain in development at this point. The partnership will enable TELO to offer pre-order customers the option to add up to three Aptera solar panel kits to their truck configuration:

  • Rooftop Truck Cab Solar Paneling – Integrated panels over the cab maximize daily energy generation.
  • Tonneau Truck Bed Cover Solar Paneling – A solar-equipped bed cover adds power while preserving storage versatility.
  • Camper Shell Solar Paneling – Panels extending from the cab over the bed increase charging capacity and storage options.

Aptera says its proprietary solar panels can generate up to 200 watts when exposed to peak sunlight, translating to about 1 to 2 kWh of free energy from the sun per day, depending on the location of the vehicle and the given season. This partnership news follows a successful showing from the solar EV startup at CES 2025 in Las Vegas as it continues to trudge forward in hopes of reaching scaled SEV production.

Although Aptera’s flagship solar EV is further down the development path than the TELO truck, both are trying to pave a new path in sustainable mobility and have paired up in hopes of continuing that uphill battle together. Per Aptera co-founder and co-CEO Steve Fambro:

Our unique curved solar cell design makes it the perfect application to propel automotive utility further than ever before. Together with TELO, we’re harnessing the power of the sun to make life off the grid a reality for everyone by putting the sun to work for them.

TELO and Aptera shared that the three solar panel options outlined above will become available on MT1 truck pre-orders later this year. TELO says its first fully realized drivable truck prototype is being assembled now by Aria Group, so hopefully, we can move on from renderings and see some bonafide production-intent solar electric trucks soon. TELO co-founder and CEO Jason Marks also spoke:

Whether buyers are looking for a commuter vehicle, a safer, more sustainable option to serve their family’s needs, a rugged, dependable pickup truck for outdoor adventuring, or a highly-functional fleet & vehicle that increases their business’s efficiency, TELO continues to be a first-in-class automotive option to satisfy the many needs of car buyers.

For now, you can reserve a TELO MT1 for $152 – a nod to the overall length of the stubby pickup.

Solar farms generating 724 MW in Oklahoma will power Google AI

A group of Oklahoma solar farms collectively generating a whopping 724 megawatts (MW) will power Google’s data center operations and artificial intelligence (AI) with long-term power purchase agreements.

Leeward Renewable Energy announced that the solar farms are strategically sited to support Google’s operations and bolster Oklahoma’s grid.

Construction has begun on the 372-MW Mayes County Solar Portfolio, located within a mile of Google’s data center in Pryor, Oklahoma, northeast of Tulsa. Together with the 152.5 MW Twelvemile Solar Project 1 & 2 and the 200 MW Twelvemile 3 Solar Project in southern Oklahoma, the projects total 724 MW of solar capacity.

The Mayes County Solar portfolio is capable of powering the equivalent of over 865,000 homes annually and avoiding over 3.7 million metric tons of CO2 emissions over the term of the power purchase agreement.

Leeward Renewable Energy purchased the Mayes County Solar Portfolio earlier this year from Red River Renewable Energy. The energy generated by the solar portfolio is delivered to Oklahoma’s largest utility, Grand River Dam Authority, which will power Google’s data center with clean energy.

The Mayes County Solar Portfolio includes three solar projects: 145 MW Salt Branch Solar, 125 MW Huckleberry Solar, and 102 MW Mayes Solar. Together, these projects will create over 300 construction jobs and generate an estimated $76 million in tax revenue for Mayes County over their lifespans – funds that will go toward essential county initiatives and schools. More than $60,000 has already been donated to local organizations like the Red Cross, the Chamber of Commerce, and other key services, giving an extra boost to community resources. They’re expected to come online by the end of the year.

“By partnering with Grand River Dam Authority and Leeward Renewable Energy, Google is furthering its ambition to power our facilities, including those in Oklahoma, with carbon-free energy around the clock by 2030,” said Amanda Peterson Corio, global head of data center energy at Google. “These power purchase agreements demonstrate how our scalable procurement approach is transforming the acquisition of clean energy and accelerating the development of carbon-free energy sources.“

In August 2024, research released by CBRE Group found that the amount of data center supply under construction in North America’s top markets jumped by about 70% year-over-year to a record 3.9 gigawatts of power, Reuters reported.
