ACCRA, GHANA — Up until February, Janet Maingi didn’t think much about bitcoin. Born and raised in the Kenyan capital of Nairobi, Maingi had instead spent more than twenty years focused on trying to solve one of Africa’s biggest problems: connectivity. To that end, she spent more than 20 years working in operations in the telecom industry, in companies specializing in internet and wireless networks to cable and satellite television. But earlier this year, the 45-year-old mother decided to take on the continent’s second-biggest issue: Its energy problem.
Africa is a renewable energy mecca. There’s an estimated 10 terawatts of solar capacity, 350 gigawatts of hydro, and another 110 gigawatts of wind, according to data from Energy, Capital & Power, an investment platform focused on Africa’s energy sector.
Some of this renewable energy is being harnessed already, but a lot of it isn’t, because it is expensive to build the kind of specialized infrastructure necessary to capture it. Even though Africa boasts 60% of the best solar resources globally, the continent only has 1% installed solar PV capacity, according to the International Energy Agency.
“When you sit back and look at rural Africa and rural Kenya, one of the things that is very prevalent in the homes — I am talking about the 50% that are not electrified — is children have to do their assignments using either paraffin lamps or candles,” Maingi told CNBC on the sidelines of the Africa Bitcoin Conference in Accra.
“Think of their eyesight, think of their health,” she said.

Maingi was frustrated by the divide between generation and capacity, given that 43% of Africa’s population, or 600 million people, lack access to electricity. So in February, she began spitballing creative solutions with two friends, and the three of them landed on a sort-of counterintuitive idea: bitcoin mining.
Mining for the world’s biggest cryptocurrency is a process known as proof-of-work. Miners around the world run high-powered computers that collectively validate transactions and simultaneously create new tokens. The process requires a lot of electricity, and because this is the only variable cost in a low-margin industry, miners tend to seek out the world’s lowest-cost sources of power.

Bitcoin gets a bad rap for the amount of energy it consumes, but it can also help to unlock these trapped renewable sources of energy. Bitcoin miners are essentially energy buyers, and when they co-locate with renewables, it creates a financial incentive for buildout and improves the core economics of renewable power production. The IEA says that in rural areas “where over 80% of the electricity-deprived live, mini-grids and stand-alone systems, mostly solar based, are the most viable solutions.”
By May, Maingi and her two colleagues decided to try it out. They founded a venture called Gridless to see whether the additional demand of bitcoin miners on these semi-stranded assets could make renewables in Africa economically viable — and crucially, whether the additional source of energy could power communities previously out of reach of microgrids that electrify parts of Africa.
Gridless also has plans to expand into other parts of Africa with the help of a fresh injection of cash.
Jack Dorsey’s digital payments firm Block and Alyse Killeen’s bitcoin-focused venture firm Stillmark, have led a $2 million seed investment into the company, which Gridless says it plans to use to open new mines.
Maingi is the chief operations officer, and her two friends turned co-founders, chief executive Erik Hersman, and chief financial officer Philip Walton, have spent the last several months launching pilots across Kenya in which they work with mini-grid hydro and solar generators to use their excess capacity to mine.
“We had spent years building internet connectivity infrastructure in rural and urban Africa, and realized that you cannot have a 21st-century economy without both power and connectivity together,” Hersman told CNBC.

“As we looked at the next problem to solve, we realized that bitcoin mining solved a major problem for renewable mini grid energy developers, in that we could be their industrial off-taker for stranded power, no matter where they were located, thereby making them more sustainable and increasing electrification across Africa,” continued Hersman.
Gridless currently has three operational pilot sites in Murang’a, a rural town that’s a 90-minute drive northeast of Nairobi. Each mine runs on hydroelectric power from HydroBox, an energy company based on the continent. Two of the mines have about 50 kilowatts of capacity, and by Thursday, the third mine will expand to 300 kilowatts.
To put those numbers into perspective, 30 kilowatts would power about 500 households. 50 kilowatts is closer to 800 households.
In January, Gridless plans to launch another 50-kilowatt hydromine in Malawi and its first solar-powered site in West Africa that will have a 30 kilowatt capacity.
Lowering energy costs
So far, the economics make a lot of sense for everyone involved. Gridless serves as a sort of anchor tenant. The company finances construction and manages the operation of data centers in rural communities where traditional industrial or commercial customers are not available, according to a company statement released Tuesday.

Because the power supplier benefits from selling energy that previously had been discarded, the energy plants will sometimes lower costs for the end user. At one of their pilot sites in Kenya, for example, the hydro plant dropped the price of power from 35 cents per kilowatt hour to 25 cents.
The buildout of capacity is also electrifying households. Gridless says they’ve already seen this translate to containerized cold storage for local farmers, battery charging stations for electric motorcycles and public WiFi points.
Once those types of needs are met, Gridless said in a statement that the remaining electricity capacity is used to power the bitcoin mine.
“Bitcoin and mining is really the tool. We’re not doing bitcoin for bitcoin,” said the lead for bitcoin mining and wallet at Block, Thomas Templeton. “The whole objective is really to empower these villages. Bitcoin is a means to that end.”
Block previously announced in April it would be teaming up with Blockstream to break ground on a solar- and battery-powered bitcoin mine in Texas that uses solar and storage technology from Tesla.
Block is also working on a project to make bitcoin mining more distributed and efficient.
Making the mining process more accessible has to do with more than just creating new bitcoin, according to Templeton. Instead, he says the company sees it as a long-term need for a future that is fully decentralized and permissionless.
The company is solving one major barrier to entry: Mining rigs are hard to find, expensive and delivery can be unpredictable. Block says it is looking into making a new ASIC, which is the specialized gear used to mine bitcoin.
Democratizing access to the mining process is big for Block. Right now, Africa accounts for around 0.2% of the global bitcoin hashrate (an industry term used to describe the collective computing power of the entire network),according to the Cambridge Centre for Alternative Finance. The bulk sum of the hashpower shifted from China to the U.S. over the last 18 months after Beijing banned crypto mining. Many in the industry tell CNBC that this kind of centralization is a problem.
“Decentralized mining is essential for the resiliency of bitcoin,” said Templeton, who added that Block kicked off its mining initiative to make mining more accessible, user-friendly and reliable, so that more people can mine.
It was a sentiment echoed by Dorsey in Accra on Tuesday morning. The Block CEO, who said he still plans to move to Africa for six months, added that Block wants to partner with other companies on the continent to make it easier to onboard people into bitcoin.
“We’re working on a hardware miner to make it more, hopefully, accessible and more efficient for people around the world and especially on the continent to participate in securing the network and making it even more resilient in the form of something that’s also useful for other things, not just mining.”
Supporting the rise of bitcoin mining across Africa also translates to another big goal for Block: Helping to accelerate global renewable hashrate.
“Gridless represents a close strategic alignment with our vision of ensuring the bitcoin network increasingly leverages clean energy, in combination with bitcoin computational centers around the world,” said Templeton.
Rivian will power its DC fast-charging network with renewable energy company RWE’s Champion Wind farm in Texas.
The two companies just signed a 15-year power purchase agreement (PPA) for electricity from RWE’s repowered Champion Wind in Nolan and Mitchell counties, west of Abilene.
The 127-megawatt (MW) Champion Wind is getting new turbine nacelles and blades, which will extend the wind farm’s lifespan. Originally commissioned in 2008, the wind farm is expected to be fully upgraded by mid-2025. When the wind farm is back online, it’ll be capable of generating enough electricity to power nearly 1 billion miles of renewable driving every year for Rivian, or the equivalent of powering 36,000 homes annually in Texas.
This wind power is set to support Rivian’s DC fast-charging Adventure Network with renewable energy. Rivian has set a specific goal to enable 7 billion miles of renewable driving.
Paul Frey, Rivian’s VP of propulsion, charging & adventure products, said, “Champion Wind is a powerful enabler for Rivian drivers to become active participants in building a cleaner grid every time they charge their vehicle. This project shows the potential to meaningfully decarbonize the grid and support a more circular economy through reuse and recovery of existing infrastructure, all while maintaining highly competitive economics.”
Siemens Gamesa is supplying 41 turbines with new nacelles and blades on existing towers. The nacelles and blades are being manufactured in the US. In addition, as part of the repowering project, six new Siemens Gamesa turbines rated at 3.1 MW each will also be added to the wind farm.
The decommissioned wind turbine blades from Champion will be repurposed. RWE is working with REGEN Fiber, an Iowa-based company that recycles wind turbine blades to make reinforcement fibers for the construction industry. Those fibers are then used in concrete to add strength and durability, extending the lifespan of infrastructure.
RWE is the third-largest renewable energy company in the US.

Rivian is bringing back its “All-Electric upgrade offer” from now until November 30th, but with some changes to the program.
Earlier this year, Rivian offered $1k-$5k off a new Rivian if you trade in an old gas car, from April to June. The offer was available for specific vehicles, and with a sliding discount scale based on which Rivian vehicle you order.
Now the program has come back, but with quite a few changes from the previous version.
As of today, October 31, if you buy a new Rivian R1T or R1S new inventory vehicle from the R1 Shop, you can get a $3,000 discount if you also prove that you own or lease a qualifying gas-powered vehicle.
This is simultaneously simpler, more lenient, and more restrictive than the previous offer, in various ways.
First, the discount is a flat $3k (or $4,100 CAD), rather than having a scale based on what model you order, which is more streamlined.
Second, the discount applies to every gas or hybrid vehicle owner – you don’t have to trade in your vehicle, and you’re not limited to a specific list of vehicles. Just prove that you own or lease a gas car (copy of registration, proof of insurance, etc), and you get the discount.
However, third, it’s more restrictive as to what vehicles you can purchase. The current offer applies only to Rivian new inventory vehicles in the R1 Shop, and excludes demo vehicles, pre-owned vehicles, or custom build vehicles. It also does not apply to Rivian’s base Dual Standard models, but everything else is fair game.
In order to qualify, you need to place your order between today and November 30, and you must take delivery of the vehicle before December 31. Check out all the specifics of the offer on Rivian’s site here.
Electrek’s Take
Rivian is clearly trying to round out its yearly numbers with this offer, as the market for pricy cars is somewhat soft with increased interest rates. It just slightly lowered its annual delivery guidance, now planning to see roughly similar deliveries this year than last.
But its R1 vehicles just got a huge refresh to help the company with costs and to offer new features. The R1S is still one of the most popular high-priced vehicles in the US, and the company’s products earn universal acclaim from owners.
The interesting thing is that Rivian had a similar offer earlier this year, before the refresh, to help clear out inventory of older vehicles. It didn’t see it fit to offer the discount last quarter, perhaps buoyed by the updated model, but after a rough Q3 of deliveries it now brought the offer back.
Rivian is still guiding to reach a slight gross profit in Q4, though we’re sure we’ll hear more about that in its upcoming quarterly earnings next week.

Hyundai’s new low-cost EV is getting a bold design upgrade. The Hyundai Casper EV Cross was spotted for the first time in public, revealing new design elements.
Although we knew a rugged “Cross” variant was headed to Europe, this was the first time the domestic model was spotted with an upgraded design.
The Inster EV is Hyundai’s overseas version of its domestic Casper Electric model. In Korea, Hyundai’s Casper EV starts at around $20,000 (27.4 million won). Hyundai said its new EV can be bought for under $8,000 (10 million won) with subsidies.
In Europe, it starts at under $27,000 (25,000 euros). The Cross variant is built for “those looking for an EV with a more adventurous look,” Hyundai said.
Although it offers the same versatility as the standard model, the Inster EV Cross gains rugged design elements, including new front and rear bumpers, black claddings, skid plates, a roof rack, and more.
Here’s our first look at the Hyundai Casper EV Cross
After a rugged new variant with the Casper EV logo was spotted in Korea for the first time, a Cross model is expected to debut shortly.
The new video from HealerTV reveals added design elements, including the roof rack and more aggressive black trim.
The reporter notes that the Hyundai Casper EV Cross has a “much more mechanical and futuristic feel than the existing model.”
It almost appears “robot-like” with an added off-road feel. The Inster EV Cross gets up to 223 mi (360 km) WLTP driving range. In Korea, the Casper Electric is rated with up to 195 miles (315 km) driving range.
Although Hyundai Casper (Inster) EV is not expected to launch in the US, the low-cost model was spotted driving in California for the first time this month.
In the meantime, off-road fans can get in line for Hyundai’s upgraded 2025 IONIQ 5, which will be available with a rugged XRT trim. The 2025 IONIQ 5 XRT model was also recently caught testing ahead of deliveries.
