The Argentine province of Mendoza is famous for its vineyards and full-bodied Malbecs. But the popular wine region in the foothills of the Andes mountains is also home to the world’s second-largest shale gas reserve called Vaca Muerta, which translates to “dead cow.”

For two Texas-based bitcoin miners, the oil deposit offers a dream resource: wasted energy.

Brent Whitehead and Matt Lohstroh, both graduates of Texas A&M University, have been mining bitcoin on the oil fields of East Texas since 2019. That’s when they founded Giga Energy with the goal of taking flared natural gas and turning it into electricity to run bitcoin mines, which are notoriously power-thirsty.

On Tuesday, Giga announced its first foray into Argentina, following expansion across the U.S. and into Shanghai. The company is partnering with Phoenix Global Resources, an oil and gas company with operations in Mendoza, and with IT services company Exa Tech to launch a two megawatt bitcoin mine on top of Vaca Muerta.

Giga’s system involves placing a shipping container full of thousands of bitcoin miners on an oil well, then diverting the natural gas into generators, which convert the gas into electricity that’s used to power the miners. The process reduces CO2-equivalent emissions by about 63% compared to continued flaring — or burning — of unused gas, according to research from Denver-based Crusoe Energy Systems. It also turns wasted energy into a valuable asset for oil producers.

“By capturing stranded natural gas to power modular data centers for energy-intensive computing, Giga is actively contributing to reducing global methane emissions,” Whitehead told CNBC in an interview. Whitehead comes from a long line of “wildcats,” a term used to describe those who engage in high-risk exploratory drilling.

On the small pilot site in Argentina, Exa Tech is handling operations on the ground, Phoenix Global is providing the gas and Giga is supplying the equipment.

Bitcoin mining is particularly lucrative whenever there’s a bull market in the cryptocurrency, making current market conditions particularly ripe for a buildout. Bitcoin has soared 170% in the past six months, touching multiple all-time price highs of late, a rally sparked in part by optimism surrounding the launch of spot bitcoin exchange-traded funds in the U.S.

The boom has helped buoy the share prices of publicly traded bitcoin miners. Riot Platforms more than quadrupled in value last year. CleanSpark jumped more than fivefold in 2023 and is up another 112% this year. Cipher Mining soared over 600% last year and has gained 27% in 2024.

Lohstroh told CNBC that Giga has generated over $10 million in revenue so far this quarter. It’s not the only miner that sees opportunity in Argentina, which ranks 12th on the list of the top global emitters of methane, according to World Bank data.

Crusoe, which helps oil companies like ExxonMobil convert flare gas into a useful resource, helped launch a bitcoin mine at Vaca Muerta in June, as part of an ongoing effort to reduce the energy waste and environmental impacts of natural gas flaring. 

Giga’s mine is intentionally small to start and isn’t intended to be profitable yet. The company first wants to make sure it can successfully import all the necessary equipment before scaling the operation. The mine has been running a test since December, and Lohstroh estimates the site has mined in the range of $200,000 to $250,000 worth of bitcoin.

Giga projects the mine is set to reduce CO2 emissions by approximately 180,000 tons per year at the upstream facility. The site is also designed to sell any excess power to the Argentina grid as a way to both generate revenue and curb operational redundancies.

Crypto is popular in Argentina

It helps that bitcoin isn’t a hard sell in a country whose residents have long faced economic instability and wild currency fluctuations.

The government’s official figures show that annual inflation hit 211% in 2023, the highest in 32 years, further eroding the country’s purchasing power. Today, 2 in 5 Argentines live in poverty.

Vitalik Buterin, the co-creator of ethereum, previously told CNBC that crypto has far greater use cases in Argentina than in many other parts of the world, noting that he found coffee shops that accepted bitcoin and ether.

When I visited Argentina back at the end of 2021, lots of people used crypto, lots of people loved crypto,” Buterin sad. “I literally got recognized on the streets of Buenos Aires more often than I got recognized in San Francisco.”

Argentina’s president, Javier Milei, said at the World Economic Forum in January that “shock therapy” is the only way to address the profound crisis facing his country. One tactic involved devaluing the national currency by 50% in an effort to curb inflation. Milei, who took over as president in December, has embraced bitcoin and has proposed dollarizing the economy, as well as abolishing the central bank and privatizing the pension system.

“We started this before Milei went into office,” Lohstroh said. “I think it’s pretty interesting that in lockstep, in stride, we’re turning this equipment online in the region, as it’s becoming dollarized and becoming more stable and giving real investment dollars into the economy.”

Federico Brom, Exa Tech’s director of business development, says Argentina has “basically banned imports” as a way to protect its currency. That could be a headwind for scaling the bitcoin mining business.

Still, Brom said he’s seen “a lot of support, a lot of hype and a lot of interest” in what they’re offering.

EcoFlow members can save up to 65% on power stations while supporting disaster relief during the 2025 Member's Festival

Portable power station specialist EcoFlow is kicking off its third annual Member’s Festival this month and is offering a unique new rewards program to those who become EcoFlow members. The 2025 EcoFlow Member’s Festival will offer savings of up to 65% for its participating customers, and a portion of those funds will be allocated toward rescue power solutions for communities around the globe through the company’s “Power for All” fund.

EcoFlow remains one of the industry leaders in portable power solutions and continues to trek forward in its vision to power a new tech-driven, eco-conscious future. Per its website:

Our mission from day one is to provide smart and eco-friendly energy solutions for individuals, families, and society at large. We are, were, and will continue to be a reliable and trusted energy companion for users around the world.

To achieve such goals, EcoFlow has continued to expand its portfolio of sustainable energy solutions to its community members, including portable power stations, solar generators, and mountable solar panels. While EcoFlow is doing plenty to support its growing customer base, it has expanded its reach by giving back to disaster-affected communities by helping bolster global disaster response efforts the best way it knows how– with portable power solutions.

EcoFlow and its members look to provide “Power for All”

Since 2023, EcoFlow has collaborated with organizations worldwide as part of its “Power for All” mission. This initiative aims to ensure access to reliable and timely power to disaster-affected communities across the globe, including rescue agencies, affected hospitals, and shelters, to support rescue and recovery efforts.

This fund most recently provided aid for communities affected by the recent Los Angeles wildfires, assistance to the Special Forces Charitable Trust (SFCT) in North Carolina following severe hurricanes, and support for non-profits engaged in hurricane preparedness in Florida and the Gulf Coast. Per Jodi Burns, CEO of the Special Forces Charitable Trust:

In the wake of devastating storms in Western North Carolina, reliable power was a critical need for the families we serve. Thanks to EcoFlow’s generous donation of generators, we were able to provide immediate relief, ensuring these families and their communities had access to power when they needed it most. We are so impressed with EcoFlow’s commitment to disaster response through their ‘Power for All’ program. It has made a tangible impact, and we are deeply grateful for their support and partnership in helping these families recover and rebuild.

In 2024, the US experienced 27 weather and climate events, each causing losses exceeding $1 billion, marking the second-highest annual total on record, according to National Centers for Environmental Information. The increasing frequency and severity of natural disasters underscore the critical need for reliable and timely power solutions during emergencies, much like EcoFlow and its members are helping provide through the “Power For All” initiative.

To support new and existing EcoFlow members, the company is celebrating its third annual Member’s Festival throughout April to offer a do-not-miss discount on its products and donate a portion of all sales to the “Power for All” fund to provide rescue power to those in need in the future. Learn how it all works below.

Tesla loses another top talent: its long-time head of software

Tesla loses another top talent: its long-time head of software

Tesla is losing another top talent: its long-time head of software, David Lau, has reportedly told co-workers that he is exiting the automaker.

Tesla changed how the entire auto industry looks at software.

Before Tesla, it was an afterthought; user interfaces were rudimentary, and you had to go to a dealership to get a software update on your systems.

When Tesla launched the Model S in 2012, it all changed. Your car would get better through software updates like your phone, the large center display was responsive with a UI that actually made sense and was closer to an iPad experience than a car.

Tesla also integrated its software into its retail experience, service, and manufacturing.

David Lau deserves a lot of the credit for that.

He joined Tesla in 2012 as a senior manager of firmware engineering and quickly rose through the ranks. By 2014, he was promoted to director of firmware engineering and system integration, and in 2017, he became Vice President of software.

Lau listed the responsibilities of his team on his LinkedIn:

  • Vehicle Software:
    • Firmware for the powertrain, traction/stability control, HV electronics, battery management, and body control systems
    • UI software and underlying Embedded Linux platforms
    • Navigation and routing
    • iOS and Android Mobile apps
  • Distributed Systems:
    • Server-side software and infrastructure that provides telemetry, diagnostics, over-the-air updates, and configuration/lifecycle management
    • Data engineering and analytics platforms that power technical and business insights for an increasingly diverse set of customers across the company
    • Diagnostic tools and fleet management, Manufacturing and Automation:
  • Automation controls (PLC, robot)
    • Server-side manufacturing execution systems that power all of Tesla’s production operations
  • Product Security and Red Team for software, services, and systems across Tesla

Bloomberg reported today that Lau told his team he is leaving Tesla. The report didn’t include reasons for his stepping down.

Electrek’s Take

Twelve years at any company is a great run. At Tesla, it’s heroic. Congrats, David, on a great run. You undoubtedly had a significant impact on Tesla and software advancements in the broader auto industry.

He is another significant loss for Tesla, which has been losing a lot of top talent following a big wave of layoffs around this time last year.

I wonder who will take over. Michael Rizkalla, senior director of software engineering and vehicle firmware, is one of the most senior software engineers after Lau. He has been at Tesla for 7 years, and Tesla likes to promote within rather than hire outsiders.

There are also a lot of senior software execs working on AI at Tesla. Musk has been favoring them lately and he could fold Lau’s responsibilities under them.

Kia’s EV3 is the best-selling retail EV in the UK right now

Kia's EV3 is the best-selling retail EV in the UK right now

Kia’s electric SUVs are taking over. The EV3 is the best-selling retail EV in the UK this year, giving Kia its strongest sales start since it arrived 34 years ago. And it’s not just in the UK. Kia just had its best first quarter globally since it started selling cars in 1962.

Kia EV3 is the best-selling EV in the UK through March

In March, Kia sold a record nearly 20,000 vehicles in the UK, making it the fourth best-selling brand. It was also the second top-seller of electrified vehicles (EVs, PHEVs, and HEVs), accounting for over 55% of sales.

The EV3 remained the best-selling retail EV in the UK last month. Including the EV6, three-row EV9, and Niro EV, electric vehicles represented 21% of Kia’s UK sales in March.

Kia said the EV3 “started with a bang” in January, darting out as the UK’s most popular EV in retail sales. Through March, Kia’s electric SUV has held on to the crown. With the EV3 rolling out, Kia sold over 7,000 electric cars through March, nearly 50% more than in Q1 2024.

The EV3 was the best-selling retail EV in the UK in the first quarter and the fourth best-selling EV overall, including commercial vehicles.

Starting at £33,005 ($42,500), Kia said it’s the “brand’s most affordable EV yet.” It’s available with two battery packs, 58.3 kWh or 81.48 kWh, good for 430 km (270 miles) and 599 km (375 miles) of WLTP range, respectively.

With new EVs on the way, this could be just the start. Kia is launching several new EVs in the UK this year, including the EV4 sedan (and hatchback) and EV5 SUV. It also confirmed that the first PV5 electric vans will be delivered to customers by the end of the year.

Electrek’s Take

Globally, Kia sold a record 772,351 vehicles in the first quarter, its best since it started selling cars in 1962. With the new EV4, the brand’s first electric sedan and hatchback, launching this year, Kia looks to build on its momentum in 2025.

Kia has also made it very clear that it wants to be a global leader in the electric van market with its new Platform Beyond Vehicle (PBV) business, starting with the PV5 later this year.

Earlier today, we learned Kia’s midsize electric SUV, the EV5, is the fourth best-selling EV in Australia through March, outselling every BYD vehicle (at least for now). The EV5 is rolling out to new markets this year, including Canada, the UK, South Korea, and Mexico. However, it will not arrive in the US.

For those in the US, there are still a few Kia EVs to look forward to. Kia is launching the EV4 globally, including in the US, later this year. Although no date has been set, Kia confirmed the EV3 is also coming. It’s expected to arrive in mid-2026.
