From oranges and lemons grown in Spain to fish caught in the wilds of the Atlantic, many are spoiled for choice when it comes to picking the ingredients that go on our plate.

Yet, as concerns about the environment and sustainability mount, discussions about how — and where — we grow our food have become increasingly pressing.

Last month, the debate made headlines in the U.K. when the second part of The National Food Strategy, an independent review commissioned by the U.K. government, was released.

The wide-ranging report was headed up by restaurateur and entrepreneur Henry Dimbleby and mainly focused on England’s food system. It came to some sobering conclusions.

Its executive summary said the food we consume — and the way we produce it — was “doing terrible damage to our planet and to our health.”

The publication said the global food system was “the single biggest contributor to biodiversity loss, deforestation, drought, freshwater pollution and the collapse of aquatic wildlife.” It was also, the report claimed, “the second-biggest contributor to climate change, after the energy industry.”

Dimbleby’s report is one example of how the alarm is being sounded when it comes to food systems, a term the Food and Agriculture Organization of the UN says encompasses everything from production and processing to distribution, consumption and disposal.

According to the FAO, food systems consume 30% of the planet’s available energy. It adds that “modern food systems are heavily dependent on fossil fuels.”

All the above certainly provides food for thought. Below, CNBC’s Sustainable Future takes a look at some of the ideas and concepts that could change the way we think about agriculture.

Growing in cities

Around the world, a number of interesting ideas and techniques related to urban food production are beginning to gain traction and generate interest, albeit on a far smaller scale compared to more established methods.

Take hydroponics, which the Royal Horticultural Society describes as “the science of growing plants without using soil, by feeding them on mineral nutrient salts dissolved in water.”

In London, firms like Growing Underground are using LED technology and hydroponic systems to produce greens 33-meters below the surface. The company says its crops are grown throughout the year in a pesticide free, controlled environment using renewable energy.

With a focus on the “hyper-local”, Growing Underground claims its leaves “can be in your kitchen within 4 hours of being picked and packed.”

Another business attempting to make its mark in the sector is Crate to Plate, whose operations are centered around growing lettuces, herbs and leafy greens vertically. The process takes place in containers that are 40 feet long, 8 feet wide and 8.5 feet tall.

Like Growing Underground, Crate to Plate’s facilities are based in London and use hydroponics. A key idea behind the business is that, by growing vertically, space can be maximized and resource use minimized.

On the tech front, everything from humidity and temperature to water delivery and air flow is monitored and regulated. Speed is also crucial to the company’s business model.

“We aim to deliver everything that we harvest in under 24 hours,” Sebastien Sainsbury, the company’s CEO, told CNBC recently.

“The restaurants tend to get it within 12, the retailers get it within 18 and the home delivery is guaranteed within 24 hours,” he said, explaining that deliveries were made using electric vehicles. “All the energy that the farms consume is renewable.”

Grow your own

While there is a sense of excitement regarding the potential of tech-driven, soilless operations such as the ones above, there’s also an argument to be had for going back to basics.

In the U.K., where a large chunk of the population have been working from home due to the coronavirus pandemic, the popularity of allotments — pockets of land that are leased out and used to grow plants, fruits and vegetables — appears to have increased.

In September 2020 the Association for Public Service Excellence carried out an online survey of local authorities in the U.K. Among other things it asked respondents if, as a result of Covid-19, they had “experienced a noticeable increase in demand” for allotment plots. Nearly 90% said they had.

“This alone shows the public value and desire to reconnect with nature through the ownership of an allotment plot,” the APSE said. “It may also reflect the renewed interest in the public being more self-sustainable, using allotments to grow their own fruit and vegetables.”

In comments sent to CNBC via email, a spokesperson for the National Allotment Society said renting an allotment offered plot holders “the opportunity to take healthy exercise, relax, have contact with nature, and grow their own seasonal food.”

The NAS was of the belief that British allotments supported “public health, enhance social cohesion and could make a significant contribution to food security,” the spokesperson said.

A broad church

Nicole Kennard is a PhD researcher at the University of Sheffield’s Grantham Centre for Sustainable Futures.

In a phone interview with CNBC, she noted how the term “urban agriculture” could refer to everything from allotments and home gardens to community gardens and urban farms.

“Obviously, not all food is going to be produced by urban agriculture, but it can play a big role in feeding local communities,” she said.

There were other positives, too, including flood and heat mitigation. “It’s … all those benefits that come with having green spaces in general but then there’s the added plus, [which] is that you’re producing food for local consumption.”

On urban farming specifically, Kennard said it provided “the opportunity to make a localized food system” that could be supported by consumers.

“You can support farms that you know, farmers that you know, that are also doing things that contribute to your community,” she said, acknowledging that these types of relationships could also be forged with other types of farms.

Looking ahead

Discussions about how and where we produce food are set to continue for a long time to come as businesses, governments and citizens try to find ways to create a sustainable system that meets the needs of everyone.

It’s perhaps no surprise then that some of the topics covered above are starting to generate interest among the investment community.

Speaking to CNBC’s “Squawk Box Europe” in June, Morgan Stanley’s global head of sustainability research, Jessica Alsford, highlighted this shift.

“There’s certainly an argument for looking beyond the most obvious … ways to play the green theme, as you say, further down the value and the supply chain,” she said.

“I would say as well though, you need to remember that sustainability covers a number of different topics,” Alsford said. “And we’ve been getting a lot of questions from investors that want to branch out beyond the pure green theme and look at connected topics like the future of food, for example, or biodiversity.”

For Crate to Plate’s Sainsbury, knowledge sharing and collaboration will most likely have a big role to play going forward. In his interview with CNBC, he emphasized the importance of “coexisting with existing farming traditions.”

“Oddly enough, we’ve had farmers come and visit the site because farmers are quite interested in installing this kind of technology … in their farm yards … because it can supplement their income.”

“We’re not here to compete with farmers, take business away from farmers. We want to supplement what farmers grow.”

US solar sets new records as renewables nearly match natural gas – EIA

Solar provided over 10% of total US electrical generation in April, wind and solar produced almost one-quarter, and the mix of all renewable energy generated nearly a third, according to data just released by the US Energy Information Administration (EIA).

Solar set new records in April and the first third of 2025

EIA’s latest monthly “Electric Power Monthly” report (with data through April 30, 2025), which was reviewed by the SUN DAY Campaign, confirms that solar continues to be the fastest-growing source of US electricity.

In April alone, electrical generation by utility-scale solar (>1 MW) increased by 39.3% while “estimated” small-scale (e.g., rooftop) solar PV increased by 11.8%. Combined, they grew by 31.3% and provided 10.7% of US electrical output.

Utility-scale solar thermal and PV expanded by 42.4% while that from small-scale systems rose by 11.4% during the first third of 2025 compared to the same period in 2024. The combination of utility-scale and small-scale solar increased by 32.9% and was almost 7.7% of total US electrical generation for January-April, up from 6.1% a year earlier.

As a result, solar-generated electricity easily surpassed hydropower output, at 6.0%. In fact, solar is now producing more electricity than hydropower, biomass, and geothermal combined.

Wind is still the renewable energy leader

Wind turbines produced 12.6% of US electricity in the first four months of 2025. Their output was 5.9% greater than the year before.

In April alone, wind provided 13.9% of US electricity supply, essentially equal to the share provided by coal.

Wind and solar now outproduce coal and nuclear

During the first third of 2025, electrical generation by wind plus utility-scale and small-scale solar provided 20.3% of the US total, up from 18.5% during the first four months of 2024. In just the month of April, solar plus wind accounted for 24.6% of US electrical output.

During the first four months of this year, the combination of wind and solar provided 20.2% more electricity than did coal, and 13.8% more than US nuclear power plants. In April alone, the disparity increased significantly when solar + wind outproduced coal and nuclear power by 77.1% and 40.2%, respectively.

Renewables are closing in on natural gas

The mix of all renewables (wind and solar plus hydropower, biomass, and geothermal) produced 10.3% more electricity in January-April than they did a year ago (9.7% more in April alone) and provided 27.7% of total US electricity production compared to 26.3% 12 months earlier.

Electrical generation by the combination of all renewables in April alone reached a new record and provided 32.8% of total US electrical generation. Moreover, renewables are now approaching the share provided by natural gas (35.1%), whose electrical output actually dropped by 4.4% during the month.

For perspective, five years ago, in April 2020, the mix of renewables provided 24.4% of total electrical generation while natural gas accounted for 38.8%.

Consequently, the mix of renewables has further strengthened its position as the second largest source of electrical generation, behind only natural gas, with the gap closing rapidly.

Ken Bossong, the SUN DAY Campaign’s executive director, noted:

Solar is now the fastest-growing major source of electricity and is generating more than hydropower, biomass, and geothermal combined, while wind plus solar provides more electricity than either coal or nuclear power, and the mix of all renewables is nearly matching the output of natural gas.

Yet, the Trump administration and the Republican Congress are seeking to pull the rug out from underneath renewables in favor of dirtier and more expensive fossil fuel and nuclear technologies. What are they thinking?

Here's a look at the Kia EV4 GT before you're supposed to see it [Video]

Kia’s upcoming EV4 GT is gunning for the Tesla Model 3 Performance, but it’s expected to undercut the price. Could this be the affordable electric sports car we’ve been waiting for? A new video shows the Kia EV4 GT driving on US streets ahead of its debut.

Kia EV4 GT is testing in the US ahead of its debut

After launching it in Korea in April, some are already calling Kia’s first electric sedan “a box office hit.” The EV4 was the best-selling domestic electric sedan in Korea in May, its second month on the market.

Kia’s electric sedan starts at just 41.92 million won, or around $30,000 in Korea. When it arrives in the US and Europe, the entry-level EV is expected to start at about $35,000 to $40,000 (€35,000).

With its sleek, fastback silhouette, the EV4 already looks like a sports car, making it an ideal candidate for a high-performance upgrade. All the EV4 needs is a little added power. Don’t worry, Kia plans to turn up the heat very soon.

We caught our first glimpse of the interior earlier this month after a prototype was spotted outside of a Kia facility in Korea.

A new video is giving us a closer look at the Kia EV4 GT being tested in the US for the first time. The video from the folks at KindelAuto reveals a few design elements you can expect to see, like Kia’s vertical LED headlights with its signature Star Map lighting.

Although it’s still covered, you can expect to see Kia’s new Tiger Face grille design, which aligns with its latest electric models, including the EV9 and EV3.

We will have to wait until closer to launch for final prices and specs, but like Kia’s other GT vehicles, the EV4 GT is expected to feature an AWD dual-motor powertrain.

It will sit under the EV6 GT, which boasts 576 hp, enabling a 0 to 60 mph sprint time of 3.4 seconds. Will the smaller EV4 GT top it? With recent advancements in battery and powertrain technology, it wouldn’t be a surprise.

Kia will launch the EV4 in the US later this year with an EPA-estimated driving range of up to 330 miles. Additionally, it will feature a built-in NACS port, allowing it to recharge at Tesla Superchargers. With the base model expected to start at around $35,000, the high-performance GT variant could cost around $50,000 to $55,000.

In comparison, the Tesla Model 3 Performance starts at $54,990 with an EPA-est range of 298 miles. It can also accelerate from 0 to 60 mph in just 2.9 seconds.

Would you pick the Kia EV4 GT for around $50,000, or are you sticking with the Tesla Model 3 Performance? Got a better option in mind? Drop us a comment below.

Xiaomi received over 200,000 real orders for its Tesla killer in just 3 minutes

Xiaomi received over 200,000 real orders for its Tesla killer in just 3 minutes

Xiaomi has confirmed receiving over 200,000 real orders for its Tesla killer, the YU7, in just three minutes. We are referring to actual orders, with a soon-to-be non-refundable deposit.

Today, Xiaomi launched its second vehicle, the YU7, coming just four years after establishing its EV division and less than a year after introducing its first car, the SU7.

For years, we laughed at the media calling every new EV a ‘Tesla killer’, but over the last few weeks, we have reported how the YU7 might be the first real one.

At the launch event, CEO Lei Jun was not shy about making comparisons to Tesla.

While the CEO praised the automaker for its leading efficiency and ADAS system, Lei Jun released a series of slides that favorably compared the YU7 to the Model Y.

It started with a comparison of the entire dimensions of both vehicles (image translated via Google):

Xiaomi’s CEO then claimed that the new YU7 had a significantly quite cabin with much less road noises than Tesla’s best-selling SUV (image translated via Google):

In my first drive of the YU7, I did note that the cabin was ultra quiet and demonstrated it briefly in my Youtube video about the new electric SUV:

[embedded content]

The double-panned acoustic glass all around helps with that, but the vehicle’s suspension is also optimized for noise, as well as active noise cancellation throughout the car.

Xiaomi also claimed that the vehicle, especially its electro-shading sunroof, was able to keep the cabin much cooler in extreme heat than Tesla’s Model Y (image translated via Google):

Lei Jun even shared a tweet that he posted about challenging Tesla Model Y’s best-selling crown and then truly went on the attack with pricing.

Ahead of today’s event Xiaomi had already shared a lot of information about the YU7, but pricing was the last significant piece of the puzzle.

The CEO decided to release with a direct comparison of each variant to Tesla’s own Model Y variant, and it was pretty brutal.

The base YU7 starts at just 253,500 RMB (equivalent to $35,300 USD) – 10,000 RMB less than Tesla, and it offers more than 200 extra km in range (image translated via Google):

As for the YU7 Pro, it starts at 279,900 RMB (equivalent to $39,000 USD), more than 30,000 RMB less than Tesla’s Model Y Long Range and it also compares quite favorably on the main features, including range (image translated via Google):

Finally, the YU7 Max was announced at 329,900 RMB (equivalent to $46,000 USD), 25,000 RMB less than Model Y Performance, and the specs are not even close:

With these incredibly favorable comparisons to Tesla’s best-selling SUV, it’s not surprising that Xiaomi has received record demand for the YU7.

It reported having received over 200,000 orders for the new electric vehicle within 3 minutes of opening orders at 10PM local time on Thursday.

It’s also important to note that these orders represent a genuine show of interest. This is not a Cybertruck situation where Tesla claimed to have over 1 million reservations, but ended up only selling about 50,000 units.

People ordering the vehicle need to place a 5,000 RMB (~700$) deposit, which only remains refundable for a few days before the order becomes locked in.

Xiaomi has already started production of the YU7 and made units available for delivery (with configurations limited to those pre-arranged by their designers) for almost immediate delivery.

Electrek’s Take

It’s hard to overestimate just how much this shook up the industry. At an average sale price of $40,000, that’s about $8 billion in sales that Xiaomi booked in 3 minutes.

I would expect the tally to increase past 400,000 in the coming days, and it will likely lock up a significant portion of potential buyers in the segment, particularly Model Y, for an extended period.

Tesla was already experiencing problems in China and had to offer record incentives to maintain its sales, but it will now face even greater challenges in the second half of the year.

I expect that Tesla will quickly launch its lower priced stripped down Model Y to try to help demand following this beating.
