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.

$39,199 Bobcat zero turn electric lawnmower is ready for summer

,199 Bobcat zero turn electric lawnmower is ready for summer

Bobcat revealed a new, commercialized version of its battery-powered ZT6000e zero-turn electric lawnmower that promises up to eight hours of continuous runtime.

The company says its new machine can deliver up to eight hours of continuous runtime on a single charge, the ZT6000e produces zero “tailpipe” emissions while in use, and is significantly quieter than the ICE-powered competition. Perfect, in other words, for use in municipalities with strict noise regulations.

“The ZT6000e is designed for both lawn care professionals and other businesses that want to create their own professional-grade results in a more sustainable way,” said Daniel Stibral, s grounds maintenance product specialist at Bobcat. “It’s highly maneuverable, efficient, and takes on challenging mowing tasks with precision, ease and the perfect cut.”

The Bobcat ZT6000e packs a 58V, 20.4 kWh battery that can be fully recharged in about 6 hours with a 240-volt “Level 2” connection, or in about 12 hours with a “standard” 120-volt connection. Considering a full charge is enough to mow more than 23 acres, however, there should be very little “range anxiety” involved.

What’s more, Bobcat claims that, apart from routine recharge cycles, the lithium-ion battery requires no maintenance for the life of the machine.

The ZT6000e is built with a heavy-duty, dual-tubed steel frame and is powered by three electric motors to provide precise control over high and low blade speeds and make quick work of any lawn. Pricing starts at $39,199.

Electrek’s Take

Yes, the ZT6000e electric lawmower is more expensive than the 850cc gas-powered version. About 3x more expensive, in fact – but that doesn’t matter.

The fact is that more and more municipalities across the country are effectively banning internal combustion lawn equipment from lawnmowers to edgers to leaf blowers – and the ones that aren’t outright banning small engines are banning them indirectly with increasingly stringent noise regulations. Translation: if you plan on making a living in landscaping, you’re going to need to pony up for an electric mower rather sooner than later.

When you do, Bobcat’s seems like a solid choice.

Pedego Moto puts the ‘fun’ in functional transportation

Pedego Moto puts the 'fun' in functional transportation

Pedego announced a slew of big new bikes this month, and we got to try out our favorite, the Pedego Moto. This brawny, two-person, class 2/3 beast leaves its competitors in the dust in so many ways. As Micah would say, “Let’s check it out…”

We’ve talked about Pedego a ton here at Electrek, but it bears repeating. No other bike company is doing more to get Americans onto e-bikes. With their excellent brick-and-mortar stores, many, if not most, Americans’ first e-bike experience is renting or trying an e-bike at a Pedego store. And because Pedego stores and e-bikes are top-notch, those experiences are almost entirely good first impressions.

I have a store in my local town, and it is the go-to place to pick up bike accessories, get a quick tuneup, or fix something (on any bike!) . It is also a great place to meet like-minded bike riders. They often sponsor local bike rides and encourage train tourists to visit our town and see it on an e-bike, which is better for everyone than driving a car.

Pedego Moto

The Pedego Moto, at first glance, will remind you of a Juiced Scorpion or the many other copycats that came along in the years since it was introduced. I’m here to say this thing is different in a number of important ways.

The most obvious is that it is much bigger, and its seat is long enough to carry a second passenger without modifications. The 2nd rider foot pegs come with the bike in its default configuration. That stretched seat also lets taller riders slide back for that sweet leg extension when actually pedaling, which on the Moto, I found quite easy. That tapered seat, while comfy for long rides, also tapers at the front to allow easy pedaling.

Also, components are almost universally better, including turn signals, larger 210mm hydraulic brakes, and huge 20-inch wheels that will go off-road much better than others in this class. SRAM gears are going to last a lot longer than the Shimano Altus setup that many of these bikes have. And just look at those burley tires.

The battery is 922Wh at 48V which will power the bike for up to 75 miles according to Pedego but more typically about 40 at near full power with little pedalling. I don’t like that it is a proprietary connector but it fast charges the battery at 5A. I was genuinely shocked how far I could ride with just small battery drops and it will last weeks in between charges if you want it to.

Pedego has revolutionized unboxing!

Like the taller boxes we saw at Upway, Pedego is now using a taller box that allows it only to require screwing in pedals and adjusting/tightening the handlebars. Including removing the tape and bubble wrap, you can be riding the Pedego Moto within 5 minutes of opening the box.

While most Pedegos will be purchased (and tuned up) at stores, this makes the process easier for Pedego technicians and direct-to-consumer customers as well.

There’s no heavy front wheel to put on, cables to plug in, or other stuff to install. Most e-bikes take me at least a half hour to assemble and often more than an hour. Pedogo Moto? I was riding within minutes of the box being delivered. The battery came more than half charged and that was good for a day of play.

Moto Experience

Pedego bikes, though they come in all shapes and sizes generally follow a standard Class 2 system that allows the bike to go up to 20 miles/hour on throttle or pedal assist. Some of their bikes, including the Moto, can be enabled to go class 3, which is up to 28 miles per hour. However, this is only pedal assist, the throttle will stop applying power at 20mph.

This allows pedego bikes to be legal in the largest number of areas while also allowing a speedy 28mph option. In reality, the large size of the bike will put pedal-assist riding at about 25 mph, in my experience. Still quite fast for such a big bike with huge tires.

Other bike companies, including Pedego’s competitors, have various flavors of “off-road mode,” which allow the motors to spin at any speed but also make them illegal in many jurisdictions.

I found the Moto to be a great ride both on the road and on gravel. Those huge tires and soft suspension eat up those potholes like no one’s business. And, even with a passenger in the back, there’s no stopping the powerful 85nm torque motor in the back.

The Moto is best for cruising and riding around town. There it excels and turns some heads, especially in this blue variety.

Moto Safety

While this bike is large, it turns quite well with admirable wheel balance and a solid front fork.

The front light not only lets oncoming cars see the Moto well at night but it also illuminates the road well enough to ride without concern. Those big hydraulic brakes on 210mm discs are also great at stopping this big bike in its tracks.

The step-over nature of the bike makes it easy to get on and off, especially with packages or another rider on the back.

Maybe the most underrated safety item is the turn signals, which I think Pedego has done well, especially in the user interface department. But the backlight is hidden a little too far under the rear seat and is typically small for an e-bike. Still, drivers and riders will almost always see the bright light when at a medium-length distance away.

Pedego Moto Price

This is a Burley bike, and Pedego has to keep its brick-and-mortar stores going, so the price may surprise those used to fly-by-night dropship prices. It is $3995. Yes, it is a lot, but you get a lot, including white glove service and actual local people there to help out when things go wrong.

Electrek’s take

I like all 3 of Pedego’s new e-bikes and if you’ve got the cash, these e-bikes are built to last and a ton of fun. The Moto isn’t light but it rides like a much more svelt e-bike and is even great for carrying 2 people!

An off-grid solar tracker powers this EV charging station

Dartmouth College in Hanover, New Hampshire, has installed an off-grid solar tracker EV charging station for its employees.

“This solar electric vehicle charger is a part of the college’s efforts to make our [transportation systems] more sustainable”, said Marcus Welker, assistant director of sustainability at Dartmouth College [via Vermont Biz].

Solaflect Energy, based in Norwich, Vermont, designs and manufactures the Solar EV Charger. The four Level 2 charging points are powered by a 6.2-kilowatt solar array mounted on a dual-axis tracker that generates 40% more power than comparable fixed panel arrays.

The system’s 6-ton concrete foundation sits directly on parking lot lines, so it doesn’t take up any parking spaces and provides enough ground clearance for unimpeded traffic flow. Designed for climate resilience, it sheds snow quickly, stows flat in high winds, and sits high enough to avoid flooding.

Solar EV Charger operates even when the grid is down, and its transportable nature allows it to adapt as EV charging needs evolve. Here’s Dartmouth’s Solar EV Charger in action:

The off-grid solar tracker EV charger is quicker and less expensive to install than traditional grid-connected stations and avoids costly utility demand charges since there’s no need for infrastructure. Solaflect’s chargers scale easily, with one charger for every four EVs or plug-in hybrids. The company asserts that over its expected 25-year life, the system locks in 1 million miles of EV charging with minimal operating and maintenance costs.

Solaflect’s Solar EV charger is available for annual lease with no additional service costs or for purchase with a 30% federal investment tax credit. Its first installations will take place in New England, followed by a US-wide expansion.
