On a warm Johannesburg afternoon, Sipho Maseko steps out of his home and pulls a cloth over his nose. The air tastes faintly of smoke again. His seven-year-old daughter has been coughing for weeks, and the local clinic blames it on “seasonal allergies.” But Sipho knows better. He lives less than 10 kilometres from one of South Africa’s many coal-fired power plants. And the numbers are clear: the very air his family breathes is slowly killing them.
Each year, an estimated 33,000 lives in South Africa could be saved if the country pivoted fully toward clean energy. That number staggering in its simplicity represents not just data, but fathers, daughters, and entire communities suffocated by outdated energy policies.
Yet, South Africa continues to choose coal.
WHO Air Quality vs South Africa Standards
To understand the magnitude of this crisis, we need only to compare two sets of numbers.
The World Health Organization (WHO) recommends a maximum annual exposure to fine particulate matter (PM2.5) of 5 µg/m³. This tiny pollutant, small enough to enter the bloodstream has been definitively linked to asthma, heart disease, lung cancer, and premature death.
By contrast, South Africa’s national standard is currently set at 25 µg/m³, five times the WHO limit. It’s a threshold more reflective of what the country can tolerate than what its people can survive.
In areas near coal plants like Mpumalanga and parts of Gauteng, PM2.5 levels routinely exceed 30 µg/m³, according to satellite data and local air monitors. And the health impacts are not abstract. They show up in rising hospital admissions, lost school days, and empty chairs at family dinner tables.
A Family’s Reality
Sipho’s story is echoed across South Africa. In the Highveld, a region home to 12 of Eskom’s coal power stations, residents frequently report respiratory issues. A 2022 Greenpeace study identified this area as one of the world’s worst nitrogen dioxide hotspots, largely due to its dense cluster of coal-burning plants.
A local paediatrician in Emalahleni, Dr. Thandi Mhlongo, sees the cost firsthand. “I treat children with persistent bronchitis, asthma, even early signs of COPD,” she says. “And many of these cases are directly linked to air pollution. If we transition away from coal, I could have half as many patients in my clinic.”
The statistics align with her experience. A report from the Centre for Research on Energy and Clean Air (CREA) estimated that air pollution from coal in South Africa causes over 2,200 new cases of chronic bronchitis every year, and nearly 10,000 children develop asthma annually due to toxic emissions.
Benefits of Solar Energy in South Africa: A Missed Opportunity
And yet, solutions are within reach quite literally. South Africa has some of the world’s best solar potential, especially in the Northern Cape, where average solar radiation levels are among the highest globally. If fully utilized, solar could power the entire country many times over.
According to the Council for Scientific and Industrial Research (CSIR), increasing solar and wind in the energy mix could not only cut emissions by 60% by 2030, but also create up to 250,000 jobs in clean energy sectors. That’s economic growth paired with cleaner air and fewer hospital visits a triple win.
So why is the country still shackled to coal?
Roadblocks on the Path to Clean Air
South Africa’s energy policy is notoriously complex. Eskom, the state-owned power utility, has long been plagued by debt, aging infrastructure, and rolling blackouts known locally as “load shedding.”
While there have been bold promises of a Just Energy Transition, policy lags, regulatory bottlenecks, and vested coal interests have slowed real progress.
In 2023, South Africa secured $8.5 billion in international climate finance to aid its energy transition. But even this funding has been mired in debates over how it should be spent and whether it will reach local communities or be absorbed by bureaucratic overhead.
Meanwhile, the National Air Quality Officer has yet to enforce strict emissions penalties, and companies continue to operate without meeting minimum emission standards. The result? More smog. More sickness. More funerals.
The Health Benefits of Renewable Energy Transition
Despite these obstacles, there’s reason to hope. Transitioning to renewables could have enormous public health benefits, beyond just lower emissions.
Clean energy adoption has been shown globally to:
- Reduce cardiovascular and respiratory disease
- Lower mortality rates from air pollution
- Improve mental health by reducing environmental stress
- Free up public health funds for other pressing needs

If South Africa embraced renewables aggressively, the lives saved by clean energy wouldn’t just be statistical, families would be preserved, hospital beds freed, futures reclaimed.
Reimagining the Future
Sipho still hopes for a day when his daughter can play outside without coughing. When blackouts are a memory, not a routine. When jobs come not from dangerous mines, but from solar fields that stretch across the Karoo.
We’re standing at an inflection point not just technologically, but morally. South Africa has the sunlight, the science, and now even the international support to pivot away from coal. What it needs is the courage to act.
Because in the end, the true cost of coal isn’t just economic it’s human.
And no kilowatt of power should ever come at the price of a child’s breath.
