Resource-rich African nations risk missing out on the investment needed to extract and refine their mineral wealth into high-value products for the clean energy transition because they lack accurate information on what they have, experts are warning.
African countries have attracted huge interest as the world scrambles to access the minerals and metals needed for the energy transition and digital and military technologies, with investors from the US, China, the United Arab Emirates and Europe jostling to secure access to the continent’s resources.
But any knowledge of Africa’s mineral wealth is, at best, an estimate based on century-old-mapping and haphazard geological data, policy experts and investors told Climate Home News.
The United Nations says Africa is home to 30% of the world’s mineral reserves, including cobalt, copper, lithium and manganese, which are needed to manufacture batteries and other clean energy technologies.
But experts like Bright Simons, who tracks natural resource spending in Africa for the Ghana-based IMANI Centre for Policy and Education, said the 30% number is not backed by any “empirical, evidence-based assessment” of the continent’s mineral wealth. While some analysts like Simons think the figure could be an overestimate, others argue it is likely an underestimate of the continent’s mineral reserves.
Up-to-date and accurate data is critical for governments to negotiate better deals with prospecting mining companies and to help drive investment in mineral extraction and processing facilities that can add value to the continent’s resources.
But the lack of good mapping has negatively impacted the continent’s efforts to capture the economic benefits of booming mineral demand and to create jobs by extracting and processing raw materials into higher-value products before export, experts said.
Colonial maps
Under-exploration and scant information about Africa’s resources have made it challenging for states to attract investment and develop their resources, said Pritish Behuria, a political economist at the Global Development Institute at the UK’s University of Manchester.
“In many cases, former colonial powers retain more current knowledge of the kinds of mineral deposits that exist in African countries – and often, this has proven difficult to access for African governments,” he told Climate Home News.
Thabit Jacob, a researcher of extractive and energy resources at Roskilde University in Denmark, said many African countries “still rely on colonial maps”.
“There’s a growing realisation that Africa must know its true value in mineral richness and investment in geological mapping is crucial,” he added.
Mapping inequality
However, mapping investment is falling short. Africa’s share of global exploration investment has fallen in the last two decades, data shows.
In 2024 alone, both Canada and Australia received significantly more investment in geological mapping than the whole of Africa, even though the continent’s landmass is three times the size of the two countries combined, according to the Center for Strategic and International Studies.
Even in South Africa, a major mining destination, only 12% of the country has been mapped at a detailed level “which compares poorly with other popular mining destinations such as Canada and Australia where there is near complete coverage at similar scales”, explained Tania Marshall, of the Geological Society of South Africa.
Nigeria’s push to cash in on lithium rush gets off to a rocky start
To address the dearth in data, multinational institutions like the World Bank have provided African countries with finance for mapping, but have simultaneously encouraged them to liberalise and privatise their mining industries.
As a result, international investors prioritising project development have come to dominate the continent’s mining sector, crowding out state-sponsored initiatives with stronger incentives to invest in data-gathering, researchers have found.
Digging blind
Orina Chang, an investor leading geological mapping across Somaliland, which has reserves of copper and zinc ore, said she was surprised to find out that even countries attracting huge interest from institutional miners, such as the Democratic Republic of the Congo (DRC), do not have systematic up-to-date mapping.
Instead, mining firms rely on artisanal mining and surface signs, like exposed ores on the ground – and crossing their fingers, she told Climate Home News.
The mapping deficit means there is little certainty on the size and quality of mineral deposits and provides few incentives for miners to invest in processing plants, Chang explained.
“Without mapping, everyone is blindly digging and you just get people who are not interested in really investing in your country,” she said. “With mapping, you’re able to attract much better players and build plants, create jobs, drive economic growth, help the GDP.”
The rise of AI-driven exploration tools
Today, AI-driven mapping tools have created new opportunities to obtain high-precision information with less on-the-ground investment. Geophysical data and satellite imagery are fed into a model that creates a geological map which can help point to high-potential deposits.
Last year, California-based KoBold Metals, which is backed by US billionaires Jeff Bezos and Bill Gates, discovered a massive copper deposit in Zambia using AI-driven exploration. In July, the firm signed an agreement with the DRC to lead critical mineral exploration there.
But the technology is expensive and not widely available to governments.
Instead, in its 2024 Green Minerals Strategy, the African Union called for some of the revenues from mineral rents to be reinvested into mapping using low-cost techniques such as satellite imagery and drones, which are less precise.
The case for co-operation
For Gerald Arhin, a research fellow at University College London, greater regional collaboration and pooling resources could also help reduce the costs of mapping for individual governments. Last year, for example, South Africa signed an agreement with South Sudan to co-operate on mineral exploration.
“The sharing of data, industrial intelligence and technical expertise across borders could be transformative for African countries, as well as for developing countries in other regions,” Clovis Freire, who heads the Extractive Commodities Section at UN Trade and Development (Unctad), told Climate Home News.
Mapping, however, is only one element of a complicated equation when it comes to developing minerals for the energy transition, said Eszter Szedlacsek, who researches climate justice in the context of the green transition at the Vrije Universiteit Amsterdam.
“In the race for Africa’s critical minerals, deals hinge only partly on where resources are found, and more on geopolitics, investment conditions and longstanding trade ties,” she said.

Q&A: Will subsidy cuts for Chinese clean-tech exports hurt Africa’s solar boom?
In January, China announced an end to export subsidies for solar panels and a phased end to value-added tax rebates on batteries. The cuts, which took effect on April 1, have raised concerns for renewable energy markets globally, including African countries, which rely heavily on Chinese imports.
With solar increasingly becoming a reliable power source across the African continent, it has seen a boom in imports of related technology, mostly from China. The first decisive evidence of a solar take-off in Africa was recorded in 2025 when imports of solar panels from China to Africa rose sharply over 12 months, adding 60% more potential electricity generation capacity than in the previous year.
Energy think-tank Ember found that the growth was led by countries that have suffered widespread power cuts like South Africa, Nigeria and Zambia, where solar panels are increasingly appealing to businesses and households seeking reliable power without having to use expensive fossil fuel generators.
But experts fear this explosive growth could be affected by the cut in tax rebates for clean technology from China – and because of the Iran war, the prices of these technologies could rise even higher, making the transition unaffordable for many Africans.
Climate Home News spoke to Karl Boyce, Chief Executive Officer of ARC Power, a renewable energy developer that works in Africa, about what these subsidy cuts could mean for the continent, how it can prepare for price and demand shocks, and what must be done to bridge Africa’s energy access gap.
Q: How will the recent export subsidy cuts by China affect the growth of clean energy usage in Africa where it’s increasingly becoming a reliable source of power for communities?
A: China’s removal of the export subsidy will certainly impact this sector in Africa, but probably not as extensively as we might first think. Solar pricing has dropped significantly in recent years, so this might just level it out to a more realistic and stable price in the longer term.
A product shortage in the near term could be a possibility, as rushed procurement might occur to secure products ahead of the next phased rebate drop in 2027. In parallel, we have already seen shipping pricing increasing from some of our recent orders, due to the war in the Middle East.
Regarding battery storage, various potential manufacturing opportunities are being explored, but these are still nascent, despite Africa having significant amounts of the critical minerals needed for battery manufacturing.
African leaders seek investments in ailing grid infrastructure to achieve energy goals
Q: About 600 million people still lack access to electricity in Africa. What are some of the barriers to bridging this gap?
A: One reason is a lack of access to funding at scale across the sector. Another is that regulations in some African countries are still evolving and changing, which makes the process slow.
With mini-grids, it’s quite challenging because most of the connections in a community will be households who are probably paying [about] $3 a month for their power, which makes it really difficult for developers or investors to actually get their money back. It might take 10 years.


A lot of funding has gone into these solar home systems, which is great just to give people lights for the first time. But we’ve seen with all the communities where we’re working that people want more than that. They want to be able to set up their business, and they don’t just want to be able to charge their phone and have a few lights – they actually want the ability to have appliances and things like that.
I think the risk appetite for investments in solar mini-grids seems to be changing, hopefully for the better. Also we seem to be seeing more and more investors focusing on impact as well, which is so nice and so positive to see.
Q: We’re less than four years away from the deadline for the UN’s universal energy access target and the gap is still far from being bridged in Africa. Can the continent meet the 2030 target and how are initiatives like Mission 300 helping?
A: Last year at an event in Kenya, the secretary-general of Sustainable Energy for All, Damilola Ogunbiyi, was talking about the fact that the last few years were the first time energy access was actually reduced because it hasn’t kept up with population growth.
Funding gap threatens next round of IPCC climate science reports, chair warns
But, while I would confidently say that we’re not going to achieve the Mission 300 target of connecting 300 million people in Sub-Saharan Africa to electricity by 2030, I think they’ll go a long way towards it.
Even though there are only about three-and-a-half years left, with the funding that’s being focused on it, I think the World Bank seems to have made it kind of a priority now [through Mission 300]. I am hoping that there will be a big step towards it. Even if they achieve half of their target, that would be such a significant step forward.
To go further towards achieving the 2030 target, there has to be a really big push on improving regulations in the countries so they become less bureaucratic. It just speeds up the process, because that’s the thing we have seen firsthand, where even if you have funding and you have the ability to do it, things are still being slowed down by regulations.
It’s hard because you’ve got so many different countries with totally different kinds of business environments and business cultures, different regulations. This is the challenge. Obviously there’s not going to be one thing that just fixes everything across the continent.
Also, I think that the approach to funding definitely has to change. We need more concessional funding to support other funding to come in, to de-risk it slightly. Access to capital has been one of the biggest barriers. And it always frustrates me, because they always say there’s so much capital out there, but not enough good projects. But when you speak to any developer, they’re always saying the same thing: it’s just trying to access capital.
Q: ARC Power operates a model called FUSE and, with support from the World Bank under the Mission 300 initiative, you are helping fund energy access in some African countries. How are models like yours helping to move the needle in areas that lack access?
A: We were building mini-grids in Rwanda and the government changed their strategy and decided they wanted everyone connected to the national electricity grid, which is obviously very ambitious. But they basically said, we don’t want any more mini-grids in Rwanda.
Some other developers left and pulled out of the market – and it forced us to rethink how we work, and this is where we developed the FUSE model. It’s a public-private collaboration with the utility company and the government, but we’re bringing in private investment to build out their energy infrastructure.
So we’ll sign a FUSE agreement with the utility company. We will then finance, design and construct grid expansion, so this is still first-time energy access, it can still be real rural areas, but we will basically build out an extension to the national grid. We put in solar, we’ll see what’s connected and how to connect everyone.
Our strapline as a company is “to power” and we are very clear with the utility companies and governments that when we go into an area we want to connect everyone. We’ll connect everyone and then once it’s all constructed and built, and the utility company has ensured it’s to their standards and they sign off, then they pay us over, say, 10 years.
What this is allowing us to do is really accelerate energy access. So, for each dollar invested, we can probably do five times as many connections as we would have been able to do if we were building just a mini-grid, just because we get our capital back quicker.
It’s also good for households because one of the challenges you have is often that you might have a utility company and a mini-grid developer almost competing for a site.
The other thing is the tariffs. You have to have this kind of cost-reflective tariff as a mini-grid operator to get your money back, which means it could be five times the price of the national grid tariff. In Rwanda, we saw houses connected to the national grid probably 500 metres away from a house that’s connected to a mini-grid and the house connected to the mini-grid is paying five times the price.
To meet Africa’s clean energy goals, investors urged to tolerate higher risk
Q: Which would serve Africa better – is it mini-grids, utility-scale renewables that can be fed into the grid, or smaller-scale rooftop installations that serve households?
A: In Rwanda, the FUSE model definitely works. Because it’s a small country, nowhere is more than probably a few kilometres from the grid. In some of the larger countries like Mozambique – which is a great example where we’re operating – I think there will always be a requirement for mini-grids, but they complement each other.
In places where you’ve got the national grid infrastructure and it’s growing slowly, we would go to the utility company and say: “You obviously have your plan of where you would like to expand the grid, and all of these tens of thousands of houses that you’d like to connect – let us do it, and we will bring in funding from the private sector”, and then it makes it much more affordable and we can accelerate it.
India sets achievable green electricity and emissions intensity targets
West Africa is absolutely on our radar, it’s where we will be definitely targeting. At the moment we are in Rwanda, Mozambique and Zambia, we’re targeting another eight countries in East and Southern Africa in the next six months, and then our plan is to go and start pitching to West African countries.
The World Bank and its International Finance Corporation arm have clearly said to us that they’ve seen the FUSE model can be one of the key solutions in this Mission 300 because it’s so scalable.

How Forests Start to Fail, One Leaf at a Time
In a Swiss forest lab, scientists tracked how beech and oak leaves cool themselves and pinpointed the moment heat and drought push them past their limits.
In spring and summer, the canopies of oak and beech forest gather into layers of green. Leaves flicker, shaping the flow of light and air. The effect is almost effortless, a shaded world held in balance. But as heatwaves and droughts, that balance is starting to slip, and the first signs of stress often first appear in leaves before spreading across entire forests.
