Steel Makers Discover Solar Power, And It Ain’t All Sweetness And Light
Oh the irony, it burns! Solar power is supposed to open the door on a new era in which humans and their ecosystems exist in harmony, but for now the record is still stuck on fossil energy. Oil, gas, and coal producers continue to dig up carbon from underground and disburse it about the surface, and solar power is becoming an enabler, providing power to operate — and equip — drilling sites and mines.
More Solar Power For Fossil Fuels
The use of solar power in the fossil energy industry should come as no surprise. After all, extractive energy sites need energy to operate, and the expense of building new transmission lines or ferrying fuel to remote locations can be formidable.
Solar power became the solution after the first practical solar cell was introduced in 1954. Oil producers were the solar industry’s leading customer by 1980, with an emphasis on use at offshore drilling sites.
Those early solar devices were limited in scale, but that changed as solar technology improved. Drillers began installing the first large-scale solar arrays for oil and gas operations in the US as early as 2003.
Alongside a sharp drop in the cost of solar cells, the scale of solar activity at drilling sites and mines has picked up significantly in recent years.
Fossil energy stakeholders have begun leaning on solar power and other renewables to fend off critics with new pledges to reduce carbon emissions. However, when fossil energy stakeholders pledge to decarbonize, they mostly mean reducing carbon emissions from operations under their direct control. Once their product reaches the marketplace, it’s a different story.
In effect, renewable energy is giving fossil energy stakeholders license to keep pumping out more product, exploring more sites for extraction, and building new pipelines, leaving energy consumers to hold the carbon emissions bag.
More Solar Power For Sustainable Steel
That brings us to the latest news about solar power and steelmaking. Steel is one of those tough-to-decarbonize industries, and steel is also the material that makes pipelines and other fossil energy infrastructure. Fossil energy stakeholders could give themselves many brownie points for transitioning their infrastructure to steel made with renewable energy.
For example, last year CleanTechnica was among those to welcome plans for a new solar array at the longstanding Rocky Mountain steel mill in Pueblo, Colorado. The mill is currently owned by the North American branch of Russia’s leading steel and coal producer EVRAZ, and the project has been developed by Lightsource bp, a joint venture between bp and the solar firm Lightsource.
Aside from enabling the mill to offset about 90% of its electricity with solar power, the project also helps to hasten the closure of the nearby Comanche coal power plant.
Why Rain On The Solar Parade?
At the time, the steel mill’s ability to churn out a new generation of extended-length rails for railroads was so exciting that we totally forgot to take a look at its other branches of its business. Our friends over at Colorado Public Radio report that the mill is also known for producing well casings, mainly for oilfields in Texas and North Dakota, in addition to producing steel pipe for, you guessed it, pipelines.
The cat’s out of the media bag now. Earlier this week bp announced that the new solar array, dubbed Bighorn Solar, is now up and running,
According to bp, the new solar array will have the carbon-reducing effect of “removing 92,100 fuel-burning cars from the road,” which is fine if carbon emissions from the mill were the only emissions in question. The bigger problem is that millions of carbon-emitting cars still rule the global roadways, and millions of car buyers are switching over to bigger vehicles that burn more gas.
That’s a problem for bp and EVRAZ, both of which have taken the opportunity to burnish their green cred by touting “the world’s first steel mill to be powered largely by solar energy,” while continuing along with their fossil energy operations.
“It is the largest on-site solar facility in the US dedicated to a single customer, with more than 750,000 solar panels providing nearly all the plant’s annual electricity demand,” bp enthused in a press release earlier this week. “This will enable the mill to produce some of the world’s greenest steel and steel products.”
Dave Lawler, chairman and president of bp America, piled on with this comment:
“Bighorn Solar shows us what the future of American energy can look like. Renewable energy can create a more sustainable, competitive business. Projects like this can make companies more resilient and protect jobs through the energy transition. And it’s another example of how bp is working to help the US and the world reach net zero by 2050.”
Do tell! Just last summer, bp CEO Bernard Looney seemed to be anticipating that the oil and gas industry would continue to be a leading customer for steel products, if not from the Rocky Mountain mill then from others. In a widely circulated interview with Bloomberg News, Looney foresaw a strong, continuing recovery in demand globally.
It’s Time To Get Serious About Decarbonizing
Looney is not alone. OPEC is also anticipating that oil demand will beat pre-pandemic levels by next year, and demand for coal is practically through the roof.
In terms of promoting a nice, green public image, that is a problem for EVRAZ and bp. On its part, EVRAZ appears to be ready to resolve part of the problem. As of last January the company was reportedly mulling over the idea of spinning off its coal business to concentrate on steel making.
The sharp uptick in coal demand may have prompted EVRAZ to set those plans aside for now, but the idea could still be percolating. Vanadium is EVRAZ’s other main business branch, and that should help cushion the separation from coal, considering the growing market for vanadium in energy storage as well as steel making.
Last year, EVRAZ also launched a new vanadium R&D center in Switzerland, focusing on expanding its use in the steel industry. That still leaves the door open for fossil energy customers, but EVRAZ seems to have its eye on the growing demand for green steel by the auto industry, which is pivoting into battery electric cars as well as fuel cell electric trucks and other heavy-duty vehicles.
No such cushion is at hand for bp. The company is pretty much stuck tinkering around the edges of decarbonization while continuing to pump out oil and gas.
Still, cleantech investments by bp and several other fossil energy firms are not insignificant, and those that invest the big bucks on cleantech gain an important public relations edge over the others.
That could be the motivation behind two interesting solar power moves that bp made right in ExxonMobil’s backyard, the US. The biggest media play went to the company’s gigantic new 9-gigawatts solar acquisition in Texas, announced last June.
Less attention went to a 132-megawatt project in Arkansas, which bp also announced last summer. That sounds like peanuts compared to the Texas buy, and it is, but in the context of solar power growth in Arkansas it’s a huge step forward.
As of halfway through 2021, solar developers in Arkansas were drifting in the range of 12 megawatts or less. Activity finally began to scale up in 2019 after a sea change in the state’s solar policies. The Arkansas branch of Entergy was leading the way, and now bp has spotted an opportunity to stake its claim in a market ripe for rapid growth.
All else being equal, the surging cost of oil and gas for home heating should help juice solar activity in Arkansas and elsewhere, so stay tuned for more on that.
As for the Rocky Mountain steel mill, one day in the sparkling green future it will churn out less well casings and more parts for solar arrays, wind turbines and electric vehicles, but today is not that day.

At CES2025, the impressively built-out John Deere exhibit was all about automation. Autonomous job sites, autonomous farms … but it was this new, battery electric, autonomous lawn mowing robot that stole the show.
The self-driving Deere mower robot was positively dwarfed by the giant farm machinery surrounding it, but it continues to prove that humans will pack bond with anything as more than one burly-looking and grizzled man asked what its name was. (It’s Howard. I’ll fight you.)
For his part, Howard packs a 21.4 kWh battery pack that runs a suite of electric motors that includes a drive motor and three cutting blade motors spread across a 60 inch cutting deck – but it’s not the electric motors that make John Deere’s little robot mower cool, it’s the way it works.
See, instead of using “just” GPS data or “just” repeating a pre-recorded run, Howard can do something in between. The way it was explained to me, you would ride the stand-up mower around the perimeter of the area you wanted to mow, select a pattern, then hop off, fold up the platform, and let it loose. Howard mows just the way you would, leaving you to focus on edging, planting, or (let’s face it) schmoozing with the clients.
It’s exactly the sort of help landscapers are looking for.
But that should come as no surprise, of course. John Deere, perhaps more than most companies, knows its customer. “We’ve been in the turf business for 60 years — it’s a core part of Deere,” says Jahmy Hindman, chief technology officer at John Deere, explaining things beautifully. “The work that’s being done in this industry is incredibly labor intensive … they’re not just doing the mowing work. They’re doing the tree trimming, maintaining flowerbeds and all these other jobs. The mowing is table stakes, though, for them to get the business. It’s the thing they have to do in order to get the higher value work.”
Tim Lewis, lead engineer with the commercial automatous mower, told Lawn & Landscape that the industry in general has a high turnover rate as well, making it difficult to hang to people who know where one job ends and another begins. “There’s a lot of nuances it takes to do these jobs effectively,” he explains, “so “Autonomy can help with that.”
The John Deere autonomous commercial mower (there’s no snazzy alphanumeric, yet) leverages the same camera technology as other Deere autonomous machines, but on a smaller scale (since the machine has a smaller footprint). With two cameras each on the front, left, right, and rear sides of the little guy, he has a 360-degree view of the world and enough AI to lay down a pattern, avoid an obstacle, and shut off if it thinks it’s about to mow down something (read: someone) it shouldn’t.
John Deere will have Howard on display through tomorrow at CES in the LVCC’s West Hall. If you’re in town, be sure to go say hi.

Tesla has officially unveiled the Model Y “Juniper” refresh, less than a day after uncamouflaged photos of the vehicle leaked online.
The refreshed Model Y, codenamed Juniper, has been expected for some time, and was expected to include many of the improvements of the 2023 Model 3 refresh.
In October, Chinese social media said the refresh was about to enter trial production, and just days later we saw a photo of the refreshed Model Y outside the Shanghai factory. Then last month, we heard that mass production would start in Shanghai in January, so we can expect that very soon as well.
And while Tesla said in 2024 that there’s no Model Y refresh coming “this year”, 2024 is over now, and the refresh is here.
Today, Tesla updated its Chinese website with all the information about the refreshed Model Y, with many of the same improvements as the Model 3 refresh like a quieter cabin, higher efficiency, more performance, ambient lighting and a rear screen.
According to Tesla’s site, the new Model Y can achieve 719km of range (446mi) in Long-range AWD spec with 19-inch wheels, but this is based in CLTC estimates, which are much more lenient than EPA. Previously the highest-range spec had 688km CLTC range, so that’s about a 20-mile improvement.
The 20″ wheels on the long range version will take you 662km, and RWD standard-range batteries will go 593km or 559km on the 19″ and 20″ wheels respectively.
We imagine this could translate to roughly ~350 miles of range on the top-spec Model Y on EPA ratings, but we’ll have to see when the car gets released in the US.
Acceleration has also been improved, with Tesla saying the large-battery AWD Model Y can achieve 0-100km/h (0-62mph) in 4.3 seconds, down from a previous 4.9. The RWD version does the same sprint in 5.9 seconds. Both of these numbers would be slightly shorter for 0-60 times, because of those extra 2mph at the end.
There is no performance version yet – just as with the post-refresh Model 3, which didn’t get a performance spec until later.
The exterior design is just as leaked photos suggested, with the same rear end we saw in leaks in July and the front end that we saw earlier today. Though now we get to see it in higher resolution and better lighting.
The front-end includes a Cybercab/Cybertruck-like “light bar” rather than the more traditional-looking headlights of the Model 3 refresh, and has been narrowed to remove the “duck lip” bump at the front of the hood.
Also on the front end is a new front bumper camera (again, like the Cybertruck, but unlike the Model 3), which should help with parking and also offer an additional point-of-view for Tesla’s Autopilot software. The inclusion of this camera, while it will improve Autopilot accuracy, does lead to questions over whether previously vehicles that don’t have a front bumper camera will be able to achieve the same level of accuracy as refreshed vehicles do.
And the interior design changes are also roughly as expected, though the steering wheel has undergone less radical changes than some had hoped.
Earlier today, photos leaked suggesting that the Model Y would receive a similar “squircle” steering wheel as the Cybertruck, leading to speculation that it might also receive the Cybertruck’s steer-by-wire system. But it turned out that those photos were just a Model 3 with a custom steering wheel.
The actual interior of the Model Y maintains a circular steering wheel, which suggests that it won’t get steer by wire (the steer-by-wire specification isn’t listed on Tesla’s Chinese site for the car).
It does however have photos showing missing steering column stalks, which has been a controversial feature of the Model 3.
However, looking closer at the steering wheel, the turn signal buttons from the Model 3 are not present. It looks like Tesla may have included a vestigial turn signal stalk hiding behind the steering wheel, and just deleted the PRND drive mode stalk.
This is still a controversial change, as changing drive modes through the screen isn’t the most popular feature, but the turn signal deletion was particularly egregious and it’s good to see it back. We wonder if the Model 3 might eventually gain this improvement, or whether this will be different in different regions.
Tesla says the new “acoustic glass” in the Model Y reduces interior noise significantly. The Model 3 also got this improvement, and testing does show a significant improvement in interior noise levels as a result.
The Model Y receives other interior improvements seen on the 3, like a screen for the rear seat. The Cybertruck also includes this screen.
This shot also shows the ambient lighting LED strip across the dash, which can be customized through the vehicle’s UI.
Another rear-end improvement is electric rear seats, operated through a button in the trunk. This button gives easier access to rear storage space, allowing owners to fold the rear seats up or down while loading or unloading cargo.
Tesla’s Chinese website calls these “anti-gravity” seats, but it’s unclear what exactly the improvements might be in this respect. The seats are ventilated.
First deliveries are scheduled for March in China, subject regulatory approval, though Tesla’s configurator says “the specific delivery date will vary depending on the configuration and pick-up location and other reasons.”
Tesla is offering a “Launch series” in China, something that Tesla has done with many of its cars, but hasn’t done before in the US with the Model 3/Y. It includes some unique design elements and “Launch series” badging in various parts of the vehicle.
As for other regions, they will probably have to wait. The Model 3 refresh came out in Europe first, and the US needed to wait months for it. This is particularly likely now given new US tariffs on Chinese-built cars (which are a bad idea).
Electrek’s Take
As I wrote in the Take section of our leaked photos article earlier today, this refresh is needed, because not only has the Model 3 had access to lots of improvements that the Model Y hasn’t gotten for the last year and a half or so, but Tesla is having a challenging time with sales right now.
The company just finished a year where its sales dropped for the first time since 2011 – back when Tesla only sold the low-production Roadster. This happened despite the overall global EV market surging to new heights, even though Tesla, the world’s largest EV maker (just barely), did its part to drag down the EV market by failing to grow apace with the rest.
Part of the reason for this is due to stale models – while the Model Y is Tesla’s best-selling model, it’s starting to seem a little long in the tooth, particularly given the Model 3’s upgrades. So we wondered earlier today whether the Model Y refresh could reignite Tesla’s growth.
But it’s not just about models. After all, Tesla did just finish its first full year of Cybertruck production, which is a new model, but its polarizing nature led to disappointing sales numbers.
That polarization is not helped by Tesla CEO Elon Musk, who is doing his best to harm the company and say phenomenally stupid things or make ridiculous promises basically every day (or every few minutes). His idiotic behavior is turning away customers, whether he believes it or not.
Maybe the company – not the stock – would be better off if he surrendered his title and let Tesla have a real CEO, so he can go play videogames on twitter all day instead (as he already does).
