In a clean, pressed Ecobora-branded dress, Purity Simuyu, fondly called “Prof. Purity” by pupils, shares her journey of restoration, one that has transformed not only her family and career, but also the Prosperity Self Help Group.
Located just 10 kilometers from the city centre, Prosperity Self Help Group sits in the heart of Kangemi, a densely populated peri-urban settlement. What began as a modest initiative has grown into a thriving school serving over 400 students with boarding facilities.
Today, 10 years after its inception, the school stands as a symbol of progress and dignity, powered by a newly installed 8 kW inverter and a 25 kWh solar photovoltaic system, delivering an 8.1 kW peak output. This clean energy solution powers an efficient cooking boiler for all school meals and provides reliable lighting throughout the school. The result, a safer, healthier environment for all and longer learning hours for the students.
In a quiet moment with “Prof. Purity,” I had the privilege of hearing her story of resilience, dignity, and transformation.
Born in Bungoma, Western Kenya, Purity was forced to drop out of school in Form Three following the death of both her parents. With limited options, she chose marriage, and in 2020 she moved to Nairobi with her husband and their firstborn child, Barack Kiplagat, in search of a better life.
Her journey led her to Kangemi, where the family settled in the same compound as the Prosperity Self Help Group. Determined to secure a future for her child, she approached the school’s founder, Patrick Murimi, who generously offered her child a scholarship. In 2021, after the birth of her second child, Bright Angel, Purity sought employment at the school. She was taken in and assigned responsibilities that included cleaning and cooking for the students.
At the time, the school relied entirely on firewood for cooking. This meant long, grueling days that began with sourcing firewood as early as 5 a.m. and stretched on until all tasks were complete. Her work left her clothes stained with soot, while constant exposure to smoke meant inhaling harmful fumes throughout the day. The toll on her health and that of her fellow cooks was significant. Beyond the physical strain, the visible soot on her clothing often led to stigma, with others looking down on her because of the nature of her work.
With a beaming smile, Purity recalls how the Ecobora boiler transformed her daily routine. After learning how to use it, her workday shifted. By the time we sat down for the interview at around 10 a.m., the team had already boiled hot water for the boarders to shower, prepared packed meals for fifty students on a school trip, served breakfast, boiled porridge for tea break, and cooked rice and ugali for lunch. Preparations for the evening meal were already underway, and through it all, her dress remained impeccably clean, plus she didn’t need to drink milk to counter the fumes inhaled.
Cooking with Ecobora is efficient. It uses less water and has a timer that prevents the different foods she prepares from burning. It has also made the kitchen environment cleaner. She further notes that it is cheaper to cook with electricity than to purchase firewood. Yes, the Kenya Power advert advocating cooking with electricity rather than other sources is factual.
“Prof.” is looking forward to receiving a second boiler under the AFRICA Sustainable Community Energy Networks (SCENe) project. She notes that this will further improve the lives of all at Prosperity Self Help Group school and their working conditions. It will also allow her workday to shift from starting at 5 a.m. to 7 a.m., giving her more time in the morning for herself and making the entire kitchen soot-free.
Her experience has allowed her to teach fellow institutional cooks on how to use an electric boiler and has given her the opportunity to travel as far as Uganda to train and mentor others. She has also trained in prisons, schools within Kenya and at the Ecobora head office.
She still vividly recalls her first training assignment, when one of the trainees arrived at her workplace and, upon seeing her, asked whether she was truly the trainer. The question stemmed from her appearance at the time, with visible stains on her dress. In that moment, she felt a quiet wave of emotion mixed with pride as she went on to prove, through her knowledge and confidence, that she is indeed the trainer. To date, her students still contact her for guidance when they are stuck.
As we ended the discussion, overcome with emotion, “Prof” still desires one thing. To complete her high school education and receive further training in clean cooking, as she has firsthand experience of the benefits to both her health and the environment. Purity at first glance might seem like only a cook, but as we wrapped up the session, I realized that this wonderful mother of two children is a champion and a leader in her quiet way to ensure that Kenya and Africa as a whole attain their Sustainable Development Goals – SDG 7, affordable clean energy, and SDG 4, ensuring inclusive and equitable quality education. A true inspiration.
Africa SCENE Milestones at Prosperity Self Help Group
The AFRICA SCENe project, implemented in March 2025, installed an 8 kW inverter and a 25 kWh solar photovoltaic system, delivering a peak output of 8.1 kW and valued at approximately KES 1.2 million. The immediate benefit for the Prosperity Self Help Group is the ability to power the electric cooking boilers reliably and sustainably.
The system will also enable the school to expand its services by incorporating a computer lab and other community-focused activities. As a smart energy system, it operates on an energy timetable, allowing the school to plan activities efficiently and even explore additional uses, such as communal cooking, which could serve as an extra source of income.
The installation was installed and is currently maintained by Women in Sustainable Energy and Entrepreneurship (WISEe). Members of the school team are also shadowing the engineers and researchers to better understand the system’s operational limits, energy scheduling, and basic troubleshooting, including maintenance tasks such as cleaning the solar panels. In addition, the project will train local technicians to ensure long-term technical support for the school.
Awarded on 31 January 2025 under UKRI 1321 Africa SCENe, the project brings together leading institutions, including the University of Nottingham (UK), Strathmore University (implemented through the Strathmore Energy Research Centre, Kenya), SmartKlub (UK), Edu-Cater Global (UK/Kenya), Map Kibera, WISEe and Prompt BI.
The project is co-led by Prof. Lucelia Rodrigues, Head of the Department of Architecture & Built Environment at the University of Nottingham, and Prof. Izael da Silva, Deputy Vice Chancellor for Research and Innovation at Strathmore University.
