This story is part of CNBC’s “Transmission Troubles” series, an inside look at why the aging electrical grid in the U.S. is struggling to keep up, how it’s being improved, and why it’s so vital to fighting climate change.
The network of transmission lines that carry electricity across the U.S. is old and not set up to meet the anticipated demand for clean energy sources like wind and solar.
Currently, electricity generation results in 32% of carbon dioxide emissions in the United States, mostly from burning fossil fuels like oil, coal, and natural gas. Those fuels are transported and burned where electricity is needed.
But inexpensive emissions-free sources of energy, like solar and wind, are only abundant in places where the sun shines or wind blows, and that’s not necessarily close to homes and businesses. Moreover, demand for electricity is going to rise as fossil fuels are gradually replaced for a whole host of other uses, such as electric vehicles and heat pumps.
Keeping the lights on and the air clean will require a lot of new transmission.
That creates “vulnerability,” the U.S. Department of Energy said in an announcement of an initiative included in President Biden’s Bipartisan Infrastructure Law to catalyze investment in the nation’s grid.
In 2021, the most recent year for which data is available, U.S. electricity customers were without power for slightly longer than seven hours on average, according to data from the U.S. Energy Information Administration. More than five of those seven hours were during what the EIA calls “major events,” including snowstorms, hurricanes, and wildfires. That’s a significant rise from the three-to-four-hour average for outages between 2013 (the first year the data is available) and 2016, and the main culprit is extreme weather.
“Extreme weather events like the Dixie Wildfire, Hurricane Ida, and the 2021 Texas Freeze have made it clear that America’s existing energy infrastructure will not endure the continuing impacts of extreme weather events spurred by climate change,” the U.S. Department of Energy said.
Transmission infrastructure lasts between 50 and 80 years, according to a 2021 presentation from the advisory firm, the Brattle Group. Replacing transmission infrastructure that’s reaching its age limit is likely to costing an estimated $10 billion a year, according to the Brattle Group analysis.
In addition to the increasing age, the location of the existing transmission lines is a problem.
Fossil fuels like oil, coal and natural gas are typically transported by railroads or pipelines, then burned in power plants near cities.
The electricity industry in the U.S. grew up through a patchwork of local utility companies meeting local demand, Rob Gramlich, the founder of Grid Strategies, told CNBC. The system of transmission lines in the U.S. was built to serve that model of energy generation.
Clean energy sources, like wind and solar, do not release greenhouse gas emissions, but the energy generated must be moved from where the wind and sun are strongest to where the electricity is actually used.

That’s especially true for tapping into the highest quality of wind energy, explained Princeton professor Jesse Jenkins, a macro-scale energy systems engineer.
“Wind turbine power scales with the wind speed cubed.That means the best wind power sites are eight times more productive than the worst ones, versus just twice as productive for solar,” Jenkins said.
“That greater degree of variation in wind power potential means we need to build wind farms where it’s really windy, and that tends to not be where too many people live! So wind power development is a big driver of expanded transmission needs,” Jenkins told CNBC.
It’s easier to build solar panels close to where they are needed, but “not so for wind farms,” Jenkins said.
The combination of an aging infrastructure that needs costly upgrades and an energy grid doesn’t go where clean — and cheap — forms of renewable energy are located is “unfortunately a double whammy for consumers,” Gramlich told CNBC.
“But consumers benefit from the cheap generation that transmission enables,” Gramlich said. He advocates for replacing old infrastructure with advanced technology that can handle next generation transmission needs.
“It would be such a waste to replace old assets with replacements of the same capacity and quality,” Gramlich said.

Demand will build fast
In the 1960s and 1970s, electricity construction boomed in both the United States and in Europe, said Konstantin Staschus, who has been focusing on the issue of transmission for his entire career, both in California and Europe.
“Those were the times when California was planning to have a nuclear power plant every 100 miles or so up and down the coast, many more than they ended up building in reality, because they kept projecting 7% annual electricity demand increases, which they used to have in the 60s, into the indefinite future,” Staschus told CNBC. “And they thought they would need generation and transmission coming out of the ears to cover future demands.”
But during and after the oil shocks of the 1970’s, the U.S. dramatically reduced its own energy demand. “Demand growth essentially dropped to 1 or 2% rather than seven and more or less stayed there,” he told CNBC.
From the late 1970’s through the early 2000’s, the U.S. transmission grid expanded at about 2% per year, Jenkins told CNBC.
Now, demand for electricity is going to increase rapidly as efforts to respond to global warming and mitigate the effects of climate change ramp up.
Demand for electricity in 2030 will be 14% to 19% higher than 2021 levels, according to an analysis from REPEAT(Rapid Energy Policy Evaluation and Analysis Toolkit), an energy policy project Jenkins is part of leading, and 27% to 39% higher by 2035, Jenkins said.
“A 21st century grid has to accommodate steadily rising electricity demand to power electric vehicles, heat pumps, industrial electrification and hydrogen electrolysis, and it needs to extend to new parts of the country to harness the best wind and solar resources. Both factors mean we simply need a bigger grid with more long-distance transmission,” Jenkins told CNBC.
“Throw in resiliency benefits of stronger inter-regional grid connections so a region that’s struggling with a extreme event can call on its neighbors for help, and you’ve got even more reason to build a stronger, bigger grid,” Jenkins said.
Despite decades of market dominance, it seems like the days of loud, finicky gas-powered lawnmowers may finally be behind us — and I say that because five of the highest-rated mowers on Amazon won’t burn a drop of gas.
Consumer site SlashGear recently compared the average star ratings of a number of lawn mowers on Amazon, focusing on products that had at least 2,000 reviews and a four-star average or higher, and found that battery-electric units from EGO, Greenworks, and Worx were among the top-rated mowers, regardless of fuel type:
The products on this list have the highest ratings for lawn mowers on Amazon. Not only do they have high ratings, but they also have an extensive number of reviews from customers. There are lawn mowers not included on this list with higher customer ratings, but they don’t have the same quantity of reviews.
There’s one manual push mower (sometimes called a reel mower) on that top five list, but virtually no mention of the fact that there are precisely zero gas-powered mowers on the list – despite there being more than 600 pages of results when I searched “gas mower” earlier today. And it’s that fact that seems like the Real News™ item here, not the affiliate links.

So, in that spirit, here’s a brief rundown of each of the top-performing mower brands that’s both free of ad links and in alphabetical order. Enjoy!
EGO
Power+ 56V 21″ electric mower; by EGO.
Over the past few years, the EGO brand has staked a claim to being the gold standard for cordless lawn equipment with its high-voltage 56V battery platform and premium build quality, and the brand’s self-propelled mowers regularly top customer satisfaction charts (they show 4.6-star average rating with more than 2,600 reviews).
That’s no surprise, as the EGO mowers offer superior durability, long runtimes, quick charging, and enough torque to rival (if not outperform) comparable gas models.
Greenworks
24V 13″ electric lawnmower; via Greenworks.
Another electric lawn care standard-bearer, Greenworks has been covered a number of times in these pages for everything from a powerful 60V cordless chainsaw to an electric minibike. Today, though, we’re focusing specifically on the brand’s 24V 13″ brushless electric mower – a product with a 4.3-star rating after more than 21,000 Amazon reviews. (!)
Fans of the Greenworks lawnmowers often cite their low weight, durability, ease of use, and for a small suburban yard (let’s call it a 1/4-1/2 acres, on the high side) the 13″ version shown, above, should be more than up to the task.
WORX
40V 17″ cordless lawn mower; by WORX.
Full disclaimer: I have a few WORX-branded toys in my garage, partly because of the brand’s smart, compact, and consumer-friendly approach to product design and partly because the brand’s excellent Power Share platform let users swap batteries between tools before some of the other brands figured out that was a huge selling point, giving WORX a significant head start in the logistical simplicity and convenience departments.
The results speak, meanwhile, for themselves. The brand enjoys high customer ratings for its 40V 17″ mower (above, which fits neatly between the other two options), and a growing base of users who’ve discovered that going electric doesn’t have to mean going expensive.
If you’re looking to get yourself some electric lawn equipment, keep an eye out for Electrek’s “Green Deals” posts which frequently feature big discounts. 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 there are constantly shifting incentives available elsewhere too, so even if you’ve looked into those before: look again.

This one is bound to upset the DSM purists still out there — meet the all-new Mitsubishi Eclipse Cross, an all-electric crossover with over 370 miles of range that’s rolling out to European dealers as you read this. (!)
First unveiled last month, the all-new Mitsubishi Eclipse Cross EV is one of the first fruits of the Nissan- Mitsubishi- Renault alliance to wear the Mitsubishi badge and early production versions of the new SUV have already begun rolling out of Renault’s ElectriCity Douai Plant in Cuincy, France.
“Following the launch of the Outlander plug-in hybrid EV (PHEV) and the Grandis hybrid EV (HEV), rolling out the all-new Eclipse Cross marks a crucial step in our electrification strategy in Europe,” said Takao Kato, president and chief executive officer of Mitsubishi Motors, at the vehicle’s debut. “Having developed the world’s first mass-produced BEV, Mitsubishi Motors has made it a mission to provide environmentally friendly vehicles and has been working toward achieving carbon neutrality. We will continue contributing to the realization of a decarbonized society by expanding our lineup of electrified vehicles, as well as addressing the diverse needs of our European customers.”
Smart Armor styling
Mitsubishi calls its latest Eclipse’ design language “Smart Armor,” and says that its design, “conveys robustness and security by incorporating powerful, armor-like design elements into an advanced and sophisticated smart EV design.”

I don’t know about any of that, but the design is certainly a noticeable, modern update on the Outlander and Outlander Sport that have dominated the struggling Japanese car brand’s North American product line for the last decade. So, while it may not win any awards or make into a “future classics” coffee table book, the latest Eclipse would certainly look “new” in a modern American Whole Foods parking lot.
Modern outside, modern inside
Inside, the new Mitsubishi Eclipse EV offers a comforting mix of buttons and touchscreens angled, cockpit-style, towards the driver and finished in a color palette that will be familiar to any 1st-gen DSM driver, paired with the chunky steering wheel and diamond-quilted seats that drivers familiar with Mitsubishi’s more recent SUV- and crossover-heavy are used to.
Like the exterior, the new Eclipse EV’s probably won’t win any design awards, but it seems comfortable and practical enough and — I can’t state this enough — looks to be a noticeable improvement over the previous generation. The car’s tech, connectivity, and infotainment features, too, also seem thoroughly modern:
The all-new Eclipse Cross is equipped with a vertical 12.3-inch Smartphone-link Display Audio (SDA) system, offering the latest infotainment experience. As it is a vehicle with Google built-in1, drivers can use apps like Google Assistant and Google Maps the moment they step into the car and even download additional apps via Google Play. Simply saying “Hey Google” enables drivers to operate the air conditioner, search for destinations, make phone calls, and play music—all hands-free. Both Apple CarPlay®4 and Android AutoTM are supported with wireless connectivity, offering a seamless connection to smartphones. The audio system features a Harman Kardon premium sound system with five selectable listening modes to suit any mood or preference, delivering an immersive, high-quality sound experience. In addition, four drive modes, Personal, Eco, Comfort, and Sport can be selected at will through the SDA, depending on the driver’s preferences and driving conditions. The Mitsubishi Motors mobile app enables remote access to the vehicle, including locking and unlocking, charging, and checking the parking location, all from a smartphone, enhancing everyday convenience. The model supports Firmware-Over-The-Air (FOTA) wireless software update technology, enabling drivers to easily update to the latest software environment by simply following the instructions on the SDA screen.
The all-new Eclipse Cross features up to 20 advanced driver assistance systems (ADAS)5. Ultrasonic sensors, cameras, and forward radar constantly monitor the vehicle’s surroundings to support safe driving. With a range of advanced safety technologies, including the MI-PILOT2 same-lane driver assistance system for highways and Rear Cross Traffic Alert (RCTA)2 system, it offers a safe and secure driving experience.
The new Mitsubishi Eclipse Cross EV features an 87 kWh battery good for up to 600 km (~375 miles) of range on the European cycle. That battery sends electrons to a capable 160 kW (~215 hp) electric motor that delivers 300 Nm (220 lb-ft) of torque at 0 rpm. DC fast charging can happen at up to 150 kW of charging, which (by my math) works out to something like a 25 minute 10-80% charge time.
Spanish-language site Motorpasión was able to get their hands on a preproduction version of the new Mitsubishi Eclipse and gave it a pretty solid review. You can check that out here, but we’ll be holding back our review until Fred or Micah can get their hands on one. Stay tuned.
Electrek’s Take
2026 Mitsubishi Eclipse EV; via Mitsubishi.
I’ve alluded to this a few times in this article, but it’s worth saying again: the new Eclipse Cross EVs aren’t wining awards or setting any performance records here, but they’re perfectly adequate and zippy enough to more than keep up with modern traffic. And, frankly, that’s a refreshing change of pace from an automotive market that seems to be constantly chasing the cancerous mantra of, “bigger, faster, more.”
If Mitsubishi’s US dealers aren’t positively begging for the parent company to bring this new EV to North America, they have truly lost the plot.

Tesla has engaged in a pattern of taking credit for the successes of its Full Self-Driving (FSD) software, even though the car still relies on an attentive driver, and yet blaming the driver rather than the software whenever things go badly.
But new moves towards allowing more distracted driving could make it harder for the company to blame drivers when its software fails.
Tesla has been marketing some version of its Autopilot or FSD software since 2013. Ever since then, the company has made bold pronouncements about how rapidly the software would improve, stating almost continually that fully autonomous driving would come within a year.
Autopilot and FSD have changed definitions over time, with basic Autopilot initially being an option and now being included on most vehicles, and with FSD being an additional cost on top of that, at varying prices (costing up to $15,000 at one point).
Advertisement – scroll for more content
In general, Autopilot has promised to be a driver’s aid, while FSD has promised to allow the car to fully drive itself with no human intervention when the software is finally ready.
That fully autonomous ability has yet to be delivered, but Tesla’s software does continue to improve.
At first Autopilot was merely active on highways, as soft of a “smart cruise control” system. It could hold the car in a lane and track the speed of vehicles ahead and match them.
Over time the systems have gained more capabilities, including being able to follow the car’s navigation system and take highway interchanges on its own. And throughout all this time, colloquially Teslas have very often been referred to as “self-driving cars.”
FSD can now operate not just on highways, but on surface streets. It is possible to do certain drives without a human touching the steering wheel – but a driver must always be in the driver’s seat and paying attention to the road (and Tesla will monitor you to make sure you’re doing so).
A quick primer on autonomous drive systems
This is because both Autopilot and FSD, and every software version of them that has so far been released, fall under the same high-level classification of autonomous drive systems. They’re all “Level 2” drive systems, according to the SAE levels of driving automation.
All driving automation systems are ranked from level 0-5. With level 0-2 systems, drivers are responsible for everything the car does. With a level 3 system, the car can be considered responsible at some times, and with level 4 or 5 systems, the car is always responsible.
There is one level 3 system available in the US, Mercedes DRIVE PILOT, which can be used in narrow circumstances to let the car drive for you. And autonomous driverless taxis like Waymo are level 4 systems, with no driver but the ability only to operate in certain situations or areas (Tesla’s Robotaxi is purportedly similar to Waymo, but due to the presence of a “safety monitor,” it is arguably level 2, since an operator is still in the vehicle, just not in the driver’s seat).
But Tesla’s promises about FSD would put it squarely into the “level 5” category. CEO Elon Musk has repeatedly stated that FSD will eventually be able to drive the car across the country with nobody in it, such that your car could be in New York and you could ask it to come pick you up in Los Angeles. That ability has not yet been delivered though, so we’re still in level 2 territory.
Tesla likes to crow about FSD’s improvements
Tesla proclaims quite often that its FSD system is better than human drivers, and that its level of safety is increasing over time.
It often releases data showing the number of miles between crashes, comparing miles driven by humans and miles driven by FSD. In Tesla’s released numbers, miles driven by FSD are safer than those driven by humans.
That’s not the whole story though, because the data is somewhat cherry picked. A real study on safety would attempt to rule out extraneous variables that could influence the results, and as of yet, Tesla has not conducted a robust study of that manner (in contrast, Waymo has released multiplestudies conducted through outside entities).
There is also some difference between Tesla-provided numbers and third-party numbers, showing that Tesla’s “miles between interventions” is relatively low. This is thought of as a key indicator of how close a system is to being level 4-5 capable, as ideally a self-driving car should be able to go tens of thousands of miles without needing a human to come fix something.
And in fact, none of these numbers provided by Tesla ever describe just how safe FSD is on its own. All of them rely on the combined safety of both FSD and a human driver at the same time, as humans are required to be in the seat while operating the vehicle. When that human co-driver is moved to the passenger seat and called a safety monitor, safety numbers plummet.
So Tesla frames FSD data in a positive light, but what about when something bad happens?
Tesla blames drivers when its systems fail
When there’s an accident associated with its driver-assistance systems, Tesla will be the first to claim that it had nothing to do with it, and that the driver is at fault.
This is technically true. If FSD and Autopilot are level 2 systems, then the driver is responsible for everything the car is doing. And drivers must accept an agreement in the car before activating these systems acknowledging that they must pay attention to the road at all times and are responsible for what the car does even when the systems are activated.
So, for example, when a Florida driver on Autopilot drops his phone and blows through a stop sign, hitting a car which then hits two pedestrians, killing one, Tesla will claim “this driver was solely at fault.” In that case, a judge agreed that the driver was mostly at fault, but still assigned 33% of blame to Tesla, resulting in a $243 million judgment against the company.
Part of the reason that case was decided as it was was due to Musk’s constant statements about Autopilot and FSD’s abilities. After spending so many years talking up Tesla’s self-driving abilities, it is common for drivers and the general public to think that Tesla cars “drive themselves.” But Tesla said that those statements shouldn’t have been heard at the case at all, again wanting to make this failure about the driver, not about Autopilot.
The judgment was also influenced by Tesla’s withholding of data, which tracks with the company’s aforementioned refusal to submit its FSD data to robust outside scientific study.
So we have a contradiction here: when Tesla’s systems do well, Tesla takes all the credit, even though there’s a driver in the driver’s seat. But when they do poorly, Tesla does what it can to obscure causes or to blame drivers (who, to be fair, are still tasked with operating the vehicle, despite Musk’s many hopeful statements about self-driving). It’s Schrödinger’s FSD: responsible when Tesla wants it to be, but not when Tesla doesn’t want it to be.
But that might change going forward.
Tesla’s move away from driver monitoring could open it up to more liability
So, Tesla has heretofore managed to dodge responsibility for many of FSD’s problems by alleging that the driver is responsible at all times. And it’s not wrong to point this out.
However, at this week’s shareholder meeting, Musk stated that Tesla may allow “texting and driving” within “a month or two.”
What he seemed to be referring to is Tesla’s in-car driver monitoring system, which tracks driver attention using a camera near the rear-view mirror. If the system notices that you’re looking away from the road for too long, it will warn you and then deactivate FSD and make you take over driving for yourself, to ensure you’re doing your job as a driver.
Musk said that the issue with this is that many people want to text and drive anyway, and so will turn off FSD so they can send a text, then turn it back on after the fact. Musk alleges that it would be safer for those drivers to text and drive with FSD on than having it off, so Tesla might as well go ahead and update the software to allow for this soon.
But an unintended consequence of this could be that future court cases could use Tesla’s overconfidence in this matter against the company, claiming that it wasn’t doing its job to ensure driver attention. Despite claiming that drivers are always in control of the vehicle, Musk has now told drivers that it’s okay to take their eyes off the road – and the car won’t do anything to stop you from doing so, either.
And as we saw in the Florida case, Musk’s public statements were a part of the case. So Musk’s now-overconfidence about letting drivers text and drive could certainly show up in a courtroom in the future.
The use of driver monitoring for court cases is also of specific interest to Musk, as in the past he has floated the idea that Tesla should spy on drivers with the in-car camera and use those recordings to prevail in Autopilot crash cases. Tesla’s lawyers shut this idea down at the time.
But now, moving forward, that doesn’t even matter. The CEO has stated that cars will be updated supposedly within a month or two to allow you to look away from the road. There would be no purpose to recording drivers for lack of attention, because Tesla will supposedly allow drivers to look away freely.
And even if drivers agree to always pay attention, if Tesla is giving them features that specifically encourage them not to, and those features are framed explicitly by the CEO to encourage illegal eyes-off-road activity, we think the company might have a much harder time playing its “Schrödinger’s FSD” game in court going forward.
