South Africa is becoming Africa’s digital infrastructure capital. But as American technology companies race to build the computing infrastructure needed for cloud services and artificial intelligence, a different question is emerging: who pays the environmental and social price for the AI boom?
For years, the global conversation around artificial intelligence has focused on chips, models, startups and billions of dollars in investment.
But behind every AI chatbot, image generator, autonomous system and cloud application is something much less glamorous: a physical building filled with computers, connected to enormous amounts of electricity, cooling systems, fibre networks and land.
That infrastructure is now expanding rapidly across South Africa.
And civil-society organisations are beginning to ask whether the country's scarce resources should be committed to an industry whose economic benefits, ownership structures and environmental costs are not yet fully understood.
The debate has become particularly intense around American technology companies and data-centre operators.
South Africa already hosts roughly 70% of Africa's data-centre capacity, according to recent reporting, making it the continent's dominant digital infrastructure hub. At the same time, companies such as Microsoft, Amazon and Equinix are expanding their presence.
Now activists want the expansion slowed while regulators and communities determine exactly what these facilities consume and what they return.
The protest is not against the internet
It would be easy to portray the controversy as another example of activists opposing technology.
That would miss the central argument.
The organisations challenging the expansion are not necessarily saying South Africa should reject cloud computing, artificial intelligence or digital infrastructure.
Their argument is essentially about transparency, resource allocation and accountability.
Five civil-society organisations — Housing Assembly, Foxglove, Open Secrets, Research + Action and Planetary AI Collective — submitted a report to the South African Human Rights Commission raising concerns about the country's data-centre expansion.
They called for greater disclosure of electricity and water consumption, a public register of data centres, community-benefit obligations and human-rights due diligence.
They also called for a temporary pause on new hyperscale approvals while the country develops a clearer regulatory framework.
The South African Human Rights Commission itself opened a process seeking submissions from communities, industry, academics, regulators and government bodies on the human-rights implications of the rapid expansion of data centres.
That matters.
This is no longer simply a dispute between technology companies and neighbourhood activists.
It has entered the country's formal human-rights and regulatory conversation.
Why South Africa?
There is a straightforward economic explanation for why global technology companies are interested in South Africa.
The country has comparatively advanced telecommunications infrastructure, international submarine cable connections, established financial markets and a large concentration of technology businesses.
It is also the continent's largest data-centre market.
The South African data-centre market was estimated at about $2.55 billion in 2025, with one industry forecast projecting it could reach approximately $5.28 billion by 2031.
The country's position could become even more important as African demand for computing capacity grows.
A McKinsey estimate cited by Rest of World suggests Africa's demand for compute could reach 2.2 gigawatts by 2030, roughly five times current levels.
For technology companies, this represents a massive opportunity.
Africa is still under-served by digital infrastructure compared with North America, Europe and parts of Asia.
More cloud capacity can support financial technology, e-commerce, AI applications, digital government, enterprise software and countless other services.
But that opportunity has a physical footprint.
The AI revolution needs electricity
Artificial intelligence is often presented as something that exists in the cloud.
It doesn't.
The cloud is ultimately a collection of buildings.
Inside those buildings are servers running continuously, networking equipment moving enormous quantities of data and cooling systems preventing computer hardware from overheating.
The bigger the computational workload, the greater the infrastructure requirement.
That is why the data-centre debate has become particularly controversial during the AI boom.
A hyperscale AI facility can require extraordinary amounts of electricity.
South Africa's proposed Equinix development in Cape Town has become a focal point.
Activists and their legal representatives challenged the project over what they described as insufficient information about its potential environmental and socioeconomic impact.
Reuters reported that proposed Equinix facilities could require roughly 170 MW of power, while other reporting has put the proposed facility's requirement at around 160 MW.
To put that into perspective, this is not the electricity demand of an ordinary office complex.
It is infrastructure operating at a scale that can become relevant to national and municipal energy planning.
And that raises a difficult question:
When electricity is scarce or infrastructure is constrained, who gets priority?
South Africa has already experienced the resource problem
This debate is particularly sensitive because South Africa has lived through severe electricity and water challenges.
The country experienced extensive electricity rationing and load-shedding during the energy crisis, while Cape Town famously came close to running out of municipal water during the 2018 drought.
Those experiences have changed the politics of infrastructure.
Residents therefore have a legitimate reason to ask what happens when a new industry begins consuming large quantities of resources.
Reuters reported in July that South Africa's electricity situation had improved considerably and that Eskom said it could currently meet existing data-centre demand.
That is an important counterpoint to claims that data centres are already causing an electricity shortage.
The issue is therefore not simply:
"Data centres use electricity, therefore they are bad."
The more serious question is:
What happens as demand grows?
Water may be an even more complicated issue
Electricity gets most of the attention, but cooling can make water equally important.
Computer processors generate enormous amounts of heat.
Depending on the cooling technology, data centres can use substantial quantities of water.
The activists' report to the South African Human Rights Commission estimates that the approved Equinix facilities in Cape Town could consume more than 4.4 billion litres of water annually under the cooling method examined in their analysis. The campaigners say this would be comparable to the annual household consumption of more than 18,000 South African households.
Those figures are from the campaigners' submission and should not be treated as an independently established national measurement.
The technology industry disputes the broader implication.
Teraco, one of South Africa's largest data-centre operators and a Digital Realty company, has highlighted closed-loop cooling systems that recycle water rather than continuously consuming fresh supplies.
A Reuters report noted that Teraco says a 30 MW facility using closed-loop cooling can have water consumption comparable to an average restaurant on an annual basis.
That distinction is crucial.
Not every data centre has the same water footprint.
Cooling technology, climate, facility design and operational practices can dramatically change resource consumption.
Which makes transparency even more important.
The information gap
Perhaps the most important criticism from South African civil society is not that data centres consume resources.
Everyone already knows they do.
The concern is that communities and regulators may not have a comprehensive picture of how much each facility consumes, where that electricity comes from, how much water is used, and what economic benefits remain locally.
Foxglove and its partners argue that South Africa currently lacks a comprehensive public register showing the resource footprint of every data centre.
They have called for mandatory disclosure of electricity and water consumption and an independent mechanism to monitor compliance.
This creates a fundamental governance problem.
Imagine approving a major industrial project without knowing precisely how much electricity or water it will require.
That is essentially the concern being raised over some of the new hyperscale developments.
Who owns Africa's digital infrastructure?
There is another dimension that deserves attention: ownership.
The infrastructure powering Africa's digital economy is increasingly connected to multinational corporations.
Microsoft, Amazon, Google, Equinix and Digital Realty are among the major international players operating in the South African ecosystem.
Teraco, for example, was acquired by U.S.-listed Digital Realty, while its facilities provide connectivity to major cloud platforms.
Digital Realty's African expansion demonstrates how data infrastructure has become a global investment class rather than simply a telecommunications service.
But ownership is more complicated than simply saying "America owns Africa's data centres."
Research published by Data Landscapers in 2026 found that African-controlled companies account for the majority of facilities when ownership is traced through corporate structures, although U.S.-controlled operators represent a smaller number of facilities with significant capacity concentrated in major markets including South Africa, Nigeria and Kenya.
That distinction matters.
The debate should therefore focus less on nationality alone and more on who controls the infrastructure, who captures the economic value, who carries the environmental cost and what rights communities have in decisions about it.
The jobs question
Technology companies frequently present data centres as engines of economic development.
And there are genuine benefits.
They support cloud computing, financial services, telecommunications, digital businesses and AI development.
South Africa's Communications and Digital Technologies Minister Solly Malatsi has argued that data centres are critical to economic competitiveness and the wider digital ecosystem.
But a data centre is not a factory employing tens of thousands of people.
Once construction ends, highly automated facilities can operate with relatively small permanent workforces.
This creates an important policy question:
How much local employment, tax revenue, skills development and technology transfer should communities receive in exchange for hosting infrastructure that may consume substantial resources?
Civil-society organisations have argued that the job creation potential of data centres should be examined alongside their resource demands.
That does not mean the facilities create no jobs.
It means governments should measure the benefits rather than simply assume that billions of dollars of investment automatically translate into broad-based development.
The Equinix battle could become a precedent
The controversy surrounding Equinix's proposed Cape Town facilities illustrates the problem.
Cape Town's Municipal Planning Tribunal approved the development in July despite objections from Housing Assembly and Foxglove.
The Legal Resources Centre, representing the groups, has challenged the decision, arguing that important information about electricity, water and socioeconomic impacts was missing from the planning process.
Reuters reported that the proposed facilities could require approximately 170 MW.
The activists argue that the scale of the infrastructure deserves a much more comprehensive assessment.
The company has disputed the characterisation of its plans and has said it intends to engage with stakeholders.
The dispute therefore goes beyond one building.
It could help determine how South Africa handles the next generation of AI infrastructure.
Africa has a choice to make
There is an uncomfortable irony here.
Africa needs more digital infrastructure.
It needs better internet connectivity, cloud services, AI capacity, local computing power and data infrastructure.
But Africa also cannot afford to reproduce an old development pattern in which valuable resources are committed to externally controlled industries while communities struggle to capture enough of the resulting value.
The solution is not necessarily to shut the door on technology companies.
It may be to negotiate harder.
If a company wants access to South African land, electricity, water and markets, government can ask:
What does South Africa receive in return?
That could include:
- Local employment targets.
- Skills and AI training.
- Renewable-energy investment.
- Transparent electricity and water reporting.
- Community-benefit agreements.
- Local procurement.
- Research partnerships with African universities.
- Support for African AI startups.
- Stronger data-governance requirements.
- Emergency resource-use restrictions during shortages.
- Environmental and human-rights impact assessments.
- Clear taxation and economic-value reporting.
The objective would be to ensure that digital infrastructure becomes part of South Africa's industrial strategy rather than simply another piece of infrastructure operating alongside the economy.
The bigger issue: digital sovereignty
This is where the South African debate becomes relevant to the entire continent.
Africa is moving into an era in which data, compute and electricity are becoming strategic resources.
The countries that control computing infrastructure will have enormous influence over the future of artificial intelligence.
If African businesses and governments depend almost entirely on foreign cloud infrastructure, foreign chips and foreign AI platforms, then digital dependence could become another form of economic dependence.
But the answer is not isolation.
It is capacity.
African countries need their own data centres, cloud companies, AI researchers, semiconductor strategies, energy infrastructure, technical talent and regulatory institutions.
They also need bargaining power when multinational technology companies arrive.
South Africa is being given an early warning
The significance of the current protests is therefore much bigger than one Equinix project.
South Africa may be experiencing the early stages of a challenge that other African countries will soon face.
As AI spreads, demand for computing capacity will increase.
Nigeria, Kenya, Egypt, Ghana and other African markets will also require more cloud and data-centre infrastructure.
The question is whether African governments will design the rules before the infrastructure arrives or attempt to regulate it after billions of dollars have already been invested.
South Africa is now confronting that choice.
The country's Human Rights Commission has already sought public input on the human-rights implications of the sector, while civil-society organisations are demanding stronger transparency and, in some cases, a temporary pause on new hyperscale developments.
Meanwhile, industry and government argue that data centres are essential to the country's digital economy and that technological improvements such as closed-loop cooling and renewable energy can reduce their environmental footprint.
Both sides point to real issues.
The challenge is determining what the evidence actually shows.
The question Africa should be asking
The future of AI in Africa should not be reduced to:
"How many data centres can we attract?"
A better question is:
"What kind of digital infrastructure serves African interests?"
If a data centre brings investment, reliable connectivity, skills, jobs, renewable-energy projects and local technological capacity, it can become an important part of economic development.
If the public is expected to provide scarce land, water and electricity while having little information about consumption, ownership, taxation or local benefits, the model deserves much greater scrutiny.
South Africa now has an opportunity to establish those rules while the industry is still expanding.
That makes the country's current dispute about data centres more than a fight over concrete, cooling systems and electricity cables.
It is a debate about who owns the physical infrastructure of Africa's digital future — and who gets to decide what that future costs.
