Ntitiseng Moloi, an Energy Engineer and Master of Engineering (MEng) graduate from the Department of Electrical and Electronic Engineering Science at the University of Johannesburg (UJ), has written and published an educational children’s book that introduces young readers to renewable energy in a fun and accessible way.

Titled “Winnie Catches the Sun,” the self-published book uses a relatable South African story to teach children about solar energy and how it works. Through engaging storytelling and vibrant illustrations, Moloi hopes to make complex scientific concepts easy to understand and exciting for young audiences.

Moloi holds a Bachelor of Engineering in Electrical Engineering and a Master’s in Electrical and Electronic Engineering, both from UJ. She currently works as a Project Engineer in the renewable energy sector, where she contributes to the development, construction, and operation of utility-scale renewable energy facilities.

Inspired by her professional experience, Moloi wanted to open a window into her world as an engineer and ignite children’s curiosity about science and sustainability.

“Through this book, I hope to inspire young readers to imagine how innovation and clean energy can power a brighter, more sustainable future for all,” she says.

Moloi’s contributions to the energy sector have earned her recognition as one of the Mail & Guardian’s Top 200 Young South Africans (2024) in the Energy category, celebrating her impact and leadership in advancing renewable energy solutions.

The book has also been part of a donation drive for children at Charlotte Maxeke Johannesburg Academic Hospital, where it was distributed to young patients. Within the renewable energy community, the publication has been warmly received for introducing sustainability concepts to children in an engaging and age-appropriate way — helping to foster early interest in clean energy and environmental stewardship.
