In our latest episode of Lexicon, we sat down with Johannes Amo-Aye, co-founder and CEO of MINAGIE Energy, to talk about how his company is tackling energy poverty through a locally developed hybrid renewable energy system called the Fusion Wind Turbine.
Designed and manufactured largely in Ghana, the technology combines wind and solar power in a single modular unit aimed at providing reliable electricity to rural clinics, schools, and communities.
During the conversation, Johannes discusses the childhood experiences that inspired him to become an engineer, the challenges of developing renewable energy technology for African conditions, and why he believes local ownership is just as important as technical innovation.

Frustration is the root of invention
For Johannes, he told us, the Fusion Wind Turbine journey began with a problem he experienced first-hand. Growing up in the Accra suburb of South Labadi, power cuts were a regular occurrence. Those interruptions left a lasting impression.
“One of my earliest memories was waking up in the morning in my own sweat on the floor,” he told us. As he explained, homework was often completed under candlelight, and daily life was constantly disrupted by unreliable electricity.
Rather than accepting those conditions, Johannes says the experience motivated him to find solutions. “Energy poverty wasn’t just inconvenient; it was undermining dignity,” he said.
That frustration ultimately shaped both his career and the vision behind MINAGIE Energy. “I wanted to prove that Africa could solve Africa’s problems with African solutions,” he added.
The result is the Fusion Wind Turbine, a hybrid renewable energy system designed specifically for communities where grid reliability cannot be taken for granted.
Harvesting the sun and wind
At first glance, the Fusion Wind Turbine might sound like another small-scale renewable energy system. But, according to Johannes, the key difference lies in how multiple technologies are combined into a single platform.
The system integrates a vertical-axis wind turbine with a solar arch mounted above it. The goal is to provide electricity throughout the day and night rather than relying on a single energy source.
“When the sun goes down, it’s also harnessing wind power,” Johannes told us. The design also avoids some of the maintenance requirements associated with conventional wind turbines.
Unlike traditional systems that rely on gears and lubricants, the Fusion Wind Turbine uses a gearless design. “Our system does not use a drop of oil throughout its lifespan,” he added.
According to Johannes, that lifespan is expected to be between 20 and 25 years while requiring only minimal routine maintenance, largely focused on cleaning the solar panels. The result is a system intended to be practical for remote communities where technical support may be limited and replacement parts difficult to source.
Reliability matters
While renewable energy discussions often focus on sustainability or emissions reductions, he argues that for rural healthcare facilities the issue is much more immediate. “We can’t afford power outages when lives are at stake,” he explained.
During an early site assessment, he explained, at a health facility in Ghana’s Eastern Region, a clinic administrator warned that the electricity would fail within thirty minutes. Johannes initially assumed the warning was exaggerated.
It wasn’t. “True to his word, at 12 noon, the lights went out,” he told us.
The outage occurred while his team was conducting an energy audit in the maternity ward. At that moment, Johannes began thinking about the consequences.
“What if someone I care about is being operated on or being taken care of, or a child of mine is in an incubator?” he told us. That experience reinforced the need for a system capable of delivering continuous power even when weather conditions vary.
“The hybrid approach is not just about technical efficiency. It’s about safeguarding lives and learning,” he added.
Transforming rural healthcare
Perhaps the most powerful moment in the conversation comes when Johannes describes the impact reliable electricity can have on healthcare outcomes. He recounted the story of a woman named Mavis who went into labour during the night in a rural community.
At the time, the local clinic had no reliable electricity. Midwives delivered the baby using two mobile phone torches balanced on windowsills. Under those conditions, critical warning signs were missed.
“The child was born with severe jaundice, and unfortunately, the child died,” he said. Following the installation of the Fusion Wind Turbine system, Mavis later returned to the same facility to give birth again.
This time, conditions were very different. The clinic had reliable lighting, functioning equipment and dependable power throughout the delivery. For Johannes, stories like this highlight why access to electricity matters far beyond convenience.
“Reliable energy has turned clinics from places of uncertainty into centres of trust,” he added.
Healthcare workers have also benefited, he told us. Nurses and midwives report feeling safer, more confident and better equipped to perform their jobs.
Building local ownership
Approximately 90% of the Fusion Wind Turbine’s components are manufactured in Ghana. While some specialist components, such as neodymium magnets, are imported, Johannes says local production remains central to the company’s mission.
“We want to own the product itself,” he said. He argues that local manufacturing reduces costs, creates jobs and ensures spare parts are readily available.
More importantly, it builds confidence. “People know the solution is theirs. They know it was built by their own engineers,” he told us.
That philosophy extends to maintenance. Rather than relying solely on remote monitoring systems, MINAGIE Energy trains young people within the communities where installations take place.
Through the company’s MTEDI programme, local technicians receive maintenance training, troubleshooting and system management. The goal is to ensure communities have the skills needed to maintain their own infrastructure while creating employment opportunities at the same time.
For Johannes, that local ownership is critical. “Africa is not waiting for solutions to be imported. We are building our own,” he added.
Looking ahead
MINAGIE Energy currently has installations operating in rural Ghana, but Johannes’ ambitions extend much further. The company plans to deploy additional systems, train more technicians and expand its renewable energy footprint across the continent.
There are challenges ahead, including financing, supply chains and scaling technical support networks. Yet Johannes remains optimistic.
“The Fusion Wind Turbine is more than a turbine. It is a statement,” he said.
It is a statement about local innovation, energy independence and the ability of African engineers to solve uniquely African challenges. Looking ten years into the future, Johannes envisions hundreds of installations, thousands of trained technicians and cleaner, more reliable energy for communities that have historically been left behind.
To sum up his mission in one soundbite, “reliable energy that leaves no one behind.” Whether that vision becomes reality remains to be seen, but if the stories emerging from Ghana’s rural clinics are any indication, the impact is already being felt.
