Why oil majors Shell and BP are combining solar energy and agricultural production

At Elm Branch Solar Farm, about an hour south of Dallas, Texas, a flock of sheep grazes among a vast field of solar panels. The flock’s shepherd, Amanda Stoffels, watches over it as the sheep munch on the grass and nap in the shade provided by the panels.

Stoffels owns this land, but leases it to Lightsource BP, a major solar energy developer that’s 50% owned by British oil major BP. She earns a steady monthly income from the lease payments as well as through her grazing contract with Lightsource, which pays her to graze her sheep around the panels, thereby keeping vegetation in check.

“It’s a new, modern approach to agriculture,” Stoffels says. Her contracts with Lightsource allowed her to quit her 9 to 5 job to become a full-time shepherd.

An emerging industry called agrivoltaics combines solar energy production with agricultural activities such as sheep grazing, beekeeping and crop growing. This land management strategy could help alleviate the tension between farmers and solar developers, groups that often have competing land-use interests.

“Even though the United States is a very large country with a lot of available land, every single square inch of land is either owned, protected or cherished by someone or many people. And many people do not want to see that land change or transform into something different from what it has been,” explained Jordan Macknick, the Lead Energy-Water-Land Analyst for the National Renewable Energy Laboratory.

Agrivoltaic projects, Macknick says, could be a sort of compromise. “So agrivoltaics really offers us that opportunity to continue farming, continue doing these agricultural activities while also producing clean electricity.”

Amanda Stoffels feeds her flock of sheep at Elm Branch Solar Farm in Ellis County, Texas. Stoffels earns money by leasing her land to solar developer Lightsource BP and grazing her sheep around the panels.

Crop growing on solar farms is still a nascent area of research and some farmers still have concerns.

“Solar takes some of the best land out of production because they want land that’s 1% to 4% slope,” explained Tom Koranek, a landowner and beekeeper who leases land to Lightsource and produces honey on the solar farm. That flat, treeless land is ideal for both solar panels and crop production, he says.

Still, agrivoltaic projects are as close to a win-win for farmers and solar developers as we currently have, and as the solar industry rapidly expands, experts say we can expect to see agrivoltaics expanding right alongside it.

Opening up new markets

The nation will need to build out a massive amount of utility-scale solar to meet its decarbonization goals. Given that agricultural land comprises 44% of the U.S.’ total land area, many solar developers are looking to cite new projects on farms.

“For solar developers, I think the attraction of agrivoltaics is largely that it helps with community acceptance and community excitement about solar projects” explains Becca Jones-Albertus, Director of the U.S. Department of Energy’s Solar Energy Technologies Office. “Grazing land in this country is about a third of all of our land use. And if you’re able to make that a dual use with solar energy production, you have now opened up a huge potential market space that wasn’t open before.”

Today, the U.S. has about five gigawatts of agrivoltaic projects, encompassing more than 35,000 acres across over 30 different states. While this only represents about 3% of the country’s installed solar capacity, it’s a growing industry, and farmers are taking note.

“It’s a much better financial contribution than growing crops,” said Koranek about leasing his land to Lightsource. “Crops are very risky. So some years you may make a good return and other years you may not. And so this is a steady income year every year.”

Lightsource operates a combined 615 megawatts of sheep grazing and solar power projects, around 12% of the nation’s entire agrivoltaic portfolio. The company plans to add an additional 1,058 megawatts worth of projects next year.

Shell is also involved in the space through its 44% stake in solar developer Silicon Ranch. The ranch operates 1,300 megawatts of agrivoltaic projects with an additional 900 megawatts planned over the next two years.

While most solar developers opt to lease land, Silicon Ranch buys it outright, often purchasing degraded farmland that’s no longer in production.

“We want to tell these communities that we are committed for the long haul, and we’re going to become members of these communities in meaningful ways,” said Silicon Ranch’s Co-Founder and CEO, Reagan Farr. “So our business model of owning real estate was a function of how we viewed this asset class.”

Like Lightsource, Silicon Ranch pays local ranchers to graze sheep on their solar farms. But Farr says the company has encountered a sheep shortage, leading Silicon Ranch to invest in its own flock, which it plans to grow to over 30,000 by 2030.

While there are other players in the domestic agrivoltaic market such as Enel Green Power and US Solar, Lightsource and Silicon Ranch remain the largest players in the space. American oil majors such as Chevron and Exxon haven’t invested in agrivoltaics.

Solar plus crop production

While it’s relatively well understood how to graze sheep and create pollinator habitats among solar panels, it’s a trickier prospect to grow crops below and between the panels.

Many crops such as tomatoes and broccoli can theoretically grow beneath solar panels, but the design of the solar array usually needs to be altered, often by elevating the panels so that crops can reach their full height. That gets costly, and while the economics can work for small-scale projects in markets with strong solar incentives, scaling up is a challenge.

“I would say given the existing cost of PV technology, given the existing energy markets that we have in the United States, it will be very challenging to see crop production agrivoltaics happen at a scale bigger than five megawatts at a time,” says Macknick.

But even if we won’t see utility-scale crop production and solar energy projects anytime soon, there’s still a lot of energy in this space. The Department of Energy is currently funding six agrivoltaic projects, with the goal of enabling the deployment of over 1 megawatt of projects focused on crop production, and over 10 megawatts of projects focused on grazing and pollinator habitats.

Lightsource BP says it’s interested in getting into crop production, hoping that one of its sites can serve as a test project next year. Farr says Silicon Ranch isn’t pursuing partnerships yet. But whatever route both companies, and their oil industry backers, take, community relationships and mutually beneficial land-use arrangements are going to be paramount.

“We need to bring value to the communities where we site these solar arrays, or we’re going to lose our social license to operate. And that’s going to hurt our ability to meet some of these very aggressive, renewable energy goals that we have as a country,” said Farr.

Hyundai's super-efficient Ioniq 6 updated with sportier look, 'N' model coming soon

Hyundai has unveiled the design refresh of its Ioniq 6 sedan, and announced that it will become a family of cars rather than a single model, with an N Line trim and upcoming N performance model, much like its sister car the Ioniq 5.

Hyundai has been doing great with its EVs lately, hitting sales records and getting great reviews.

Much of that focus has been on the Ioniq 5, an attractive crossover SUV with lots of capability at a good price – and a bonkers N performance version which has been breaking different kinds of records.

The Ioniq 6, conversely, hasn’t attracted quite as much attention, even though it has some records of its own (it’s the most efficient vehicle in the US… for under $70k).

Between its admittedly odd looks – much more aerodynamic and rounded than the comparatively blocky 5 – and it fitting into the less-popular (but better) sedan form factor, it just hasn’t captured as much imagination as the 5.

It has also fallen somewhat behind. The Ioniq 5 got a big update this year, including a native NACS port, the first non-Tesla mass market vehicle to hit the road with one of these included (and it even charges faster than a Tesla does on home turf). The 6, however, is still sitting on its original design from when it first started production/shipping in 2022/23.

But that’s about to change, as Hyundai is giving the model some love with a design update and some hints at new things to come.

We’ve seen spy shots of these design updates before, but now Hyundai is showing them to everyone at the Seoul Mobility Show.

Hyundai showed two models today, the standard Ioniq 6 and the “N Line,” an upgraded trim level with some interior and exterior changes to look a little more sporty. Hyundai has used similar nomenclature for its other models, and that carries over here.

Both have a redesigned front end, making it look more aggressive than the prior bulbous and aerodynamic shape, and narrower headlights.

The N Line looks even more aggressive than the standard model, though, with an even more aggressive front and rear end.

Hyundai says that the redesign will also include interior enhancements for “a more comfortable, intuitive experience,” with a redesigned steering wheel, larger climate control display, upgraded materials and redesigned center console with more physical controls.

Beyond this, the refresh was light on details – intentionally, with a full unveil of specs and changes coming later. We can imagine a lot of the improvements on the 2025 Ioniq 5 will be carried over, such as a native NACS port for example, and potentially a slightly larger or faster-charging battery.

We had also previously heard hints that an N version (yes, “N” and “N Line” are different, no, we don’t know why they used these confusing names) of the Ioniq 6 is coming, and Hyundai reiterated those hints today – even giving us a glimpse of the car in the background of one of its shots.

Now THIS one looks quite aggressive, with a bigger double wing and potentially some changes to the diffuser (it’s hard to tell from the shot, as the N Line also has a modified diffuser).

The ioniq 5N has earned rave reviews from enthusiasts for its bonkers driving dynamics and comparatively reasonable price for a true performance vehicle. But it’s still an SUV format, and frankly, an SUV will never be a sportscar no matter how many horsepower you put into it (I will die on this hill).

The 6, however, with its sedan shape and footprint, could make for a much more compelling sports package once it’s all put together. So we’re very excited to see what Hyundai can do if they apply the same magic they put into the 5 into a new 6N. Looking forward to July.

1,500 new Colorado homes will come with geothermal heat pumps

Over the next two years, homebuilder Lennar is outfitting more than 1,500 new Colorado homes with Dandelion Energy’s geothermal systems in one of the largest residential geothermal rollouts in the US.

The big draw for homeowners is lower energy bills and cleaner heating and cooling. Dandelion claims Lennar homeowners with geothermal systems will collectively save around $30 million over the next 20 years compared to using air-source heat pumps. Geothermal heat pumps don’t need outdoor AC units or conventional heating systems, either.

Geothermal systems use the sustained temperature of the ground to heat or cool a home. A ground loop system absorbs heat energy (BTUs) from the earth so that it can be transferred to a heat pump and efficiently converted into warmth for a home. Dandelion says its ground loop systems are built to last for over 50 years and should require no maintenance.

Dandelion’s geothermal system uses a vertical ground closed-loop system that is installed using well-boring equipment and trenched back into the house to connect to a heat pump. The pipes circulate a mixture of water and propylene glycol, a food-grade antifreeze, that absorbs the ground’s temperature. A ground source heat pump circulates the liquid through the ground loops and it exchanges its heat energy in the heat pump with liquid refrigerant. The refrigerant is converted to vapor, compressed to increase its temperature, then passed through a heat exchanger to transfer heat to the air, which is circulated through a home’s HVAC ductwork.

Daniel Yates, Dandelion Energy’s CEO, called the partnership with Lennar a “new benchmark for affordable, energy-efficient, and high-quality home heating and cooling.” By streamlining its installation process, Dandelion is making geothermal systems simpler and cheaper for homebuilders and homeowners to adopt.

This collaboration is happening at a time when Colorado is pushing hard to meet its clean energy targets. Governor Jared Polis is excited about the move, calling it a win for Coloradans’ wallets, air quality, and the state’s leadership on geothermal energy. Will Toor, executive director of the Colorado Energy Office, said that “ensuring affordable access to geothermal heating and cooling is essential to achieve net-zero emissions by 2050, and we’re excited to be part of such a huge effort to bring this technology to so many new Colorado homes.”

And it’s not just about cutting emissions – geothermal heat pumps help reduce peak electric demand. Analysis from the Department of Energy found that widespread adoption of these systems could save the US from needing 24,500 miles of new transmission lines. That’s like crossing the continental US eight times.

Colorado is making this transition a lot more attractive through state tax credits and Xcel Energy’s rebate programs. These incentives slash upfront costs for builders like Lennar, making geothermal installations more financially viable. The utility’s Clean Heat Plan and electrification strategy are working to keep energy bills low while meeting climate goals.

Now is a great time to begin your solar journey so your system is installed in time for those sunny spring days.

Polestar 2 removed from Polestar’s US website alongside tariff announcement

Polestar 2 removed from Polestar's US website alongside tariff announcement

Polestar has removed the Polestar 2 from its US website header in an early sign of how new tariffs will restrict choice and competition for American consumers, thus increasing prices.

The Polestar 2 is Polestar’s first full EV – the original Polestar 1 was a limited-edition plug-in hybrid.

It started production in 2020 in Luqiao, Zhejiang, China, where Polestar and Volvo’s parent corporation, Geely, was founded.

And there’s the rub: while Polestar’s newer EV, the 3 (which we just drove the new single motor version of last week), is built in South Carolina, the 2 is not.

Unfortunately, that interacts with some news that has been getting a lot of play lately: tariffs.

The US has been gradually getting stupider and stupider on the issue of tariffs, apparently determined to increase prices for Americans and decrease the competitiveness of American manufacturing in a time of change for the auto industry.

It is widely acknowledged (by anyone who has given it a few seconds of thought) that tariffs increase prices and that trade barriers tend to reduce competition, leading to less innovation.

It started with 25% tariffs on various products from China, implemented in the 2018-2020 timeframe. Then, in 2024, President Biden implemented a 100% tariff on Chinese EVs, effectively stopping their sale in the US. These tariffs included some exceptions and credits based on Volvo’s other US manufacturing, which Polestar had used to keep the most expensive versions of the 2 on sale in the US, while restricting the lower-priced versions from sale. Nevertheless, they were a bad idea.

Now, in yet another step to make America less competitive and inflate the prices of goods more for Americans, we got more tariff announcements today from a senile ex-reality TV host who wandered into the White House rose garden (which he does not belong in). These tariffs do not include the same exceptions as the previously-announced Biden tariffs.

Apparently this has all been enough for Polestar, as even in advance of today’s tariff announcements, the company suddenly removed its Polestar 2 from its website header today.

The change can be seen at polestar.com/us, where only the Polestar 3 and 4 are listed in the header area. On other sites, like the company’s Norwegian website or British website, the car is still there. The Polestar 2 page is still up on the US website, but it isn’t linked to elsewhere on the site (we’ll see how long it stays up).

We reached out to Polestar for comment, but didn’t hear anything back before publication. We’ll update if we do.

It makes sense that the Polestar 2 would still be for sale elsewhere, as it only started production in 2020. Most car models are available for at least 7 years, so this is an earlier exit than expected.

So it’s likely that all of the tariff news is what had an effect in killing the Polestar 2.

Then again, this is also just the second day of a new fiscal quarter. Perhaps the timing offers Polestar an opportunity to make a clean break – especially now that the lower-priced version of its Polestar 3 is available.

Despite the lower $67.5k base price of the new Polestar 3 variant, that represents a big increase in price for the brand, which had sold the base model Polestar 2 for around $50k originally, before all of these tariffs.

Update: Polestar got back to us with comment, but understandably, it doesn’t say much:

Polestar is a three-car company and Polestar 2 is available for customers now. There are a select number of Polestar 2s in stock at retailers that can be found on Polestar.com, but Polestar 3 and Polestar 4 will be the priority in the North American market.

Electrek’s Take

This isn’t the first car that America has been deprived of due to tariffs. The Volvo EX30, one of our most anticipated vehicles, and Electrek’s Vehicle of the Year for 2024, had its American availability pushed back due to tariffs.

Volvo decided to build the car in Belgium and export it to the US, but now that new tariffs apply to the EU as well, maybe that low-priced, awesome, fast, small EV will instead stay in Europe instead of being shipped overseas.

This shows how mercurial tariff fiats from an ignoramus are bad for manufacturing, as they mean that companies can’t make plans – and if they can’t make plans, eventually, they’ll probably just write the country making the random decisions out of their plans so they don’t have to deal with the nonsense.

And we’ve heard this from every businessperson or manufacturer representative we’ve talked to at any level of the automotive industry. Nobody thinks any of this is a good idea, because it objectively is not. All it does is make business harder, make the US less trustworthy, make things more expensive, and overall just harm America.

Yet another way that Americans are getting screwed by this stupid nonsense. 49% of you voted for inflation, and 100% of Americans are now getting it. Happy Inflation Day, everyone.
