Gas lawn equipment is horrible for health – here’s how these cities are fixing it
A new interactive mapping tool shows how a growing number of US cities and states have passed regulations restricting the use of gas-powered lawn equipment, or incentivizing the use of electric equipment, with big clean air benefits for a comparatively small investment.
While gas lawn equipment use may seem like it’s not all that big a deal at first glance, gas leafblowers and lawnmowers can actually extremely bad for air and human health – sometimes moreso than cars.
The issue is that “small off-road engines” (SOREs) usually don’t include any sort of pollution controls, and are often dirtier two-stroke engines that create more power in a small package, but emit orders of magnitude more pollution in the form of unburned particulates from the incomplete combustion process they undergo when compared to four-stroke engines.
As a result, running a gas leaf blower for an hour can produce more emissions of nitrogen oxide (NOx) and reactive organic gases (ROG) than driving a small passenger car 1,000 miles. The car still has plenty of other impacts – higher carbon emissions and energy use, contribution to sprawl and land use, oil dependency and so on – but for these specific smog-forming pollutants, SOREs have a major impact.
It’s gotten to the point where California regulators at one point said that gas lawn equipment was responsible for more NOx + ROG emissions statewide than passenger cars did. And in Colorado, lawn & garden equipment contributes about a third as much ozone as the Colorado’s large oil & gas industry, or also about a third as much as all on-road vehicles combined (including heavy duty trucks).
This pollution doesn’t just form smog and harm human health, but when it happens in residential areas as it often does, it can directly pollute the air of the homes nearby – and operators, of course, have to breathe it every day. Not only that, but the rumbling noise of lawn equipment can create quite a nuisance in residential areas, especially with the rising popularity of working from home.
As a result of all of this, regulators in many states and cities have recognized that restrictions on gas lawn equipment can give outsized air quality benefits for relatively little cost or disruption, and that’s exactly what they’ve done in many places across the country, according to a new analysis by U.S. PIRG.
The new interactive mapping tool was created by U.S. PIRG, a public interest advocacy group which focuses on a number of issues, including environment and clean air.
It shows that cities in 26 states have passed some sort of restriction on use of gas lawn equipment, or incentive to swap to electric. As you might expect, California and Colorado are leading the way here, but plenty of other states and cities have something available, including some that aren’t always known for defending clean air on the state level (like, for example, Texas),
These restrictions take several forms. From California’s statewide ban on sale of new gas lawn equipment, to city restrictions on gas leaf blowers or on any equipment over a certain noise level, to municipal use of electric equipment, or simply incentives to encourage swapping out gas for electric.
Thankfully, there are better options available these days, and they’re quite cheap compared to the outsized air quality benefits they produce.
Electric lawn equipment has improved dramatically in recent years, offering lower noise, no emissions, and just as much power as gas-powered versions. Units are often available at a similar price as gas versions, and not only that, there are incentives available to replace gas models with electric ones.
Some of the locations on the above map have focused on an incentive approach rather than limitations. So in places that have boneheadedly made it illegal for local governments to restrict the use of gas leaf blowers like Texas has, cities like Austin and Dallas have nevertheless instituted incentive campaigns to help their residents and encourage switching over.
US PIRG’s page describes several policies that cities or states can implement to help reduce the impacts of these small polluting engines, and residents can certainly talk to their representatives and encourage movement on this issue.
And if you’re looking to get yourself some gas lawn equipment, keep an eye out for Electrek’s “Green Deals” posts where deals come up quite frequently. And check with your state or regional clean air regulator to see if any rebates are available – here’s California’s page and here’s Colorado’s, but as you can see from the map, there are incentives available elsewhere too.

A new video surfacing from a Tesla demonstration in Miami this weekend shows the Optimus humanoid robot taking a nasty fall. But it’s not the fall itself that is raising eyebrows, it’s the specific hand movements the robot made on its way down, which strongly suggest it was mimicking a remote operator frantically removing a VR headset.
Humanoid robots are all the hype right now. Billions in investments are pouring in, and Elon Musk claims it will be a trillion-dollar product for Tesla, justifying its insane valuation.
The idea has been that with the advent of AI, robots in human form could use the new generalized artificial intelligence to replace humans in an increasingly larger number of tasks.
However, there are still many serious concerns about the effort, both at the ethical and technological levels.
Technologically, most humanoid robot demonstrations have relied on remote control by human operators – pointing to a remaining gap between the software and hardware.
We discussed how the robots at the “We, Robot” event were heavily teleoperated, despite Tesla not explicitly disclosing that fact to the public.
That was more than a year ago, and despite claims that Tesla has made “AI demos” of Optimus since, it appears the company still relies on teleoperation to control them during demonstrations.
The Tesla Optimus Miami Incident
This weekend, Tesla held an event called ‘Autonomy Visualized’ at its store in Miami. The goal was to showcase Tesla’s “Autopilot technology and Optimus.”
However, there was nothing “autonomous” at Tesla’s “autonomy” event.
Many Tesla fans were seen posting videos of a Tesla Optimus robot handing out bottles of water at the event. It was also seen posing for pictures and dancing.
On Reddit, someone posted a different video of the demonstration:
As you can see, Tesla Optimus moved its hands too quickly, causing some water bottles to drop to the ground. It then loses its balance and begins to fall backward.
But the most interesting part is that just before falling backward, both of its hands immediately shoot up to its “face” in a distinct grasping motion, as if pulling an object off its head.
The robot, of course, is not wearing anything on its head.
The motion is instantly recognizable to anyone who has used VR or watched teleoperation setups. It appears the human operator, likely located backstage or in a remote facility, removed their headset in the middle of operating the robot for unknown reasons.
Optimus faithfully replicated the motion of removing a non-existent headset as it crashed to the floor.
Here’s a look at how Tesla trained Pptimus with VR headsets in its lab:
Electrek’s Take
This is embarrassing, but not just because the robot fell. Robots fall; that’s part of the R&D process. Boston Dynamics blooper reels are legendary, and they never really eroded the company’s credibility.
The problem here is the “Wizard of Oz” moment.
The specific motion of removing the “phantom headset” destroys the illusion of autonomy Tesla tries so hard to curate.
Even recently, Musk fought back against the notion that Tesla relies on teleoperation for its Optimus demonstration. He specified that a new demo of Optimus doing kung-fu was “AI, not tele-operated”:
Musk said again during Tesla’s last earnings call in October:
“Optimus was at the Tron premiere doing kung fu, just up in the open, with Jared Leto. Nobody was controlling it. It was just doing kung fu with Jared Leto at the Tron Premier. You can see the videos online. The funny thing is, a lot of people walked past it thinking it was just a person.”
Musk keeps telling shareholders that Optimus will be the biggest product in history and that millions of units will be working in factories soon. But if they are still relying on 1:1 teleoperation to hand out water bottles right now, it feels like we are still far away from a useful generalized Optimus robot.

After images of an the new mid-sized electric crossover were leaked by the Chinese MIIT, Nissan pulled the wraps off its all-new NX8 – and it looks so good, I’m wondering if it couldn’t spearhead the brand’s American turnaround.
Nissan has had a rough go of it in the US, if not, well – everywhere of late. And while we may all have our own ideas about what Nissan needs to do to turn its ship around and get back to its winning ways, one thing just about every auto industry analyst seems to understand is that, at its core, Nissan’s problem is a product problem.
It doesn’t have to be this way, though. Despite what the optics of cynically slapping a Nissan badge on a decade-old Mitsubishi platform and calling it a new Rogue might have you believe, Nissan happens to have fantastic, modern new products in its production pipeline – including the all-new NX8 BEV and EREV crossover shown here. There’s just one problem: Nissan’s comeback cars are all in China.
The “N” stands for Nice
Dongfeng Nissan, a Chinese-market automotive joint venture between Dongfeng Motor Group and Nissan, has been rolling out hit after hit in recent months, like the N6 (above), which sits between the Altima and Maxima, size-wise, and offers 112 miles on a full charge of its 21.1 kWh LFP battery before its 1.5L gas engine kicks on to keep the odometer rolling.
The N6’s stablemate, the all-electric Dongfeng Nissan N7 sedan, debuted a few months earlier to rave reviews and hot sales, too – moving more than 10,000 units in the model’s first three weeks on the market.
Like its sedan siblings, the all-electric version of Nissan NX8 crossover rolls on an 800V system architecture and features a CATL-sourced LFP battery pack with 5C ultra-fast charging technology (xC is how many you can charge in an hour, effectively, so 60 minutes divided by 5 = it can charge in as little as 12 minutes). That battery reportedly sends power to a single electric motor putting out either 215 kW (~290 hp) or 250 kW (~335 hp), depending on model.
EREV version of the NX8, meanwhile, features a similar setup to the N6, pairing a 1.5L ICE producing 109 kW (~145 hp) with a 195 kW (~260 hp) electric motor. Expect the NX8 EREV to get slightly less than the N6’s claimed 112 miles of electric-only range (Chinese cycle).
The NX8 is expected to reach its first customers in April 2026. Take a look at some of the firs official photos of the new Nissan crossover, below, then let us know how you think this would do in the US in the comments section at the bottom of the page.

This week, BYD crossed a major manufacturing milestone as its battery production crossed 113 GWh in the first three quarters of 2025 – but instead of celebrating, the company is doubling down with a new “Zero Defects” initiative to bring battery quality to an even higher level.
CarNewsChina reports that the new “Zero Defects” plan at BYD was launched internally at the start of Q3, with a focus on minimizing manufacturing defects across all stages of the battery’s life, from the manufacturing line to the end user.
The initiative coincides with BYD’s growing role as a battery supplier to other automakers and its expanding battery energy storage system (BESS) business, which are giving BYD both an international footprint and global benchmarks.
In its ongoing bid to prove itself even further in the global battery market, BYD will reportedly emphasize operational efficiency, error reduction, and standardization across manufacturing, process control, and customer service, with the end goal believed to be, “management practices comparable to those of Toyota.”
BYD on a charge
The Chinese automaker seems to be going from strength to strength in 2025, having overtaken EV sales leader Tesla in China back in June and repeating the trick again by overtaking Tesla sales in Europe in August.
Combine those EV sales with the fact that its domestic traction battery production reached 113.42 GWh in just the first three quarters of the year (with 23.65 GWh, or ~20%, being supplied to outside customers – including Tesla), and you might agree that betting against BYD seems to be a bad idea.
Note that BYD has not released official details regarding performance metrics or milestones for its new Zero Defects goal, but the message is clear: BYD plans to keep getting better.
