How a Renewable Energy-Powered Bitcoin Startup Helps Electrify Rural Africa (cnbc.com) 66
CNBC visited a small group of bitcoin miners who "set up shop at the site of an extinct volcano" near Kenya's Hell's Gate National Park.
Their mine "consists of a single 500-kilowatt mobile container that, from the outside, looks like a small residential trailer." But what's more interesting is it's operated by a startup called Gridless. (According to its web site Gridless "designs, builds, and operates bitcoin mining sites alongside small-scale renewable energy producers in rural Africa where excess energy is not utilized...") Backed by Jack Dorsey's Block, Gridless electrifies its machines with a mix of solar power and the stranded, wasted energy from a nearby geothermal site. It's one of six mines run by the company in Kenya, Malawi and Zambia, powered by a mix of renewable inputs and working toward a broader mission of securing and decentralizing the bitcoin network... In early 2022, [the three Gridless co-founders] began brainstorming creative solutions for the divide between power generation and capacity, and the lack of access to electricity in Africa. They landed on the idea of bitcoin mining, which could potentially solve a big problem for renewable energy developers by taking their stranded power and spreading it to other parts of the continent.
In Africa, 43% of the population, or roughly 600 million people, lack access to electricity.... Africa is home to an estimated 10 terawatts of solar capacity, 350 gigawatts of hydro and another 110 gigawatts of wind. Some of this renewable energy is being harnessed already, but a lot isn't because building the specialized infrastructure to capture it is expensive. Even with 60% of the best solar resources globally, Africa only has 1% of installed solar PV capacity.
Enter bitcoin miners.
Bitcoin gets a bad rap for the amount of energy it consumes, but it can also help unlock these trapped renewable sources of power. Miners are essentially energy buyers, and co-locating with renewables creates a financial incentive to bolster production. "As often happens, you'll have an overage of power during the day or even at night, and there's nobody to soak that power up," said Hersman. He said his company's 50-kilowatt mining container can "take up whatever is extra throughout the day...." Demand from bitcoin miners on these semi-stranded assets is making renewables in Africa economically viable. The power supplier benefits from selling energy that previously had been discarded, while the energy plants will sometimes lower costs for the customer. At one of the Gridless pilot sites in Kenya, the hydro plant dropped the price of power from 35 cents per kilowatt hour to 25 cents per kWh.
The buildout of capacity is also electrifying households. Gridless says its sites have powered 1,200 houses in Zambia, 1,800 in Malawi and 5,000 in Kenya. The company's mines also have delivered power for containerized cold storage for local farmers, battery charging stations for electric motorcycles and public WiFi points.

It is a decentralized and universal system of currency and trade. Living in the first world the benefits likely don't seem as big to you because you enjoy a fairly stable government provided economic and banking system but for much of the world that isn't the case. My mother's ex was from Guyana, South America and when they went back they always had various schemes to hide or otherwise smuggle their travel money from customs and another bit less hidden to use to pay customs not to steal their electronics. In the world of bitcoin, you've eliminated half that problem. Throughout much of the world regimes change like the weather, property ownership and currency can vanish overnight, with crypto your money isn't impacted.
An essential element to a free society is a functioning black market and especially as governments begin to look toward the elimination of anonymous and paper currency this too becomes a critical use of bitcoin. Look at the current crackdown on narcotic pain medication in the US as part of the latest popular trend. My wife just discovered GP's literally aren't allowed to prescribe more than a 7 day supply anymore and between blood pressure issues, depression issues caused by the antidepressants they prescribe, and a general lack of effectiveness of the alternatives she needs this medication. The pain management specialist, several thousand dollars worth of ineffective treatments later, will prescribe but indicates 3.5 a day while only prescribing 2. Where will the difference come from? You figure it out. This is just one example but these edge cases will always exist and so the black market must as well.

The article is very light on any detail at all... but it implies - in several places - that this Bitcoin mining company is building generating capacity where none existed before. However the Olkaria Geothermal station at Hell's Gate [wikipedia.org] was set up in 1981, and has had multiple expansions since then - none of which were apparently funded by Gridless (they aren't even mentioned in the Wikipedia article - as of this moment). And does anyone believe Iceland needs Gridless' "help" to develop geothermal energy?
It seems to boil down to the old, specious argument that Bitcoin miners have tried to shill in the past: "we create demand, which encourages the build-out of extra capacity - some of which may serve other non-Bitcoin uses".
But basically Gridless is a leech, like every other Bitcoin-mining outfit. They're just claiming they're less of a leech than most other Bitcoin miners.
