Across South Africa, local municipalities are finding creative ways to teach young people about sustainability. One of the most successful approaches has been the Energy Efficiency Schools Competition, led by the Climate Change Mitigation Branch of different cities. In 2025, two standout programmes took place in the eThekwini Municipality and the City of Johannesburg.
In Durban, the eThekwini Municipality’s Climate Change Mitigation Branch invited all high schools to design and build models from recycled materials that show how green buildings and sustainable living could work in practice. The competition encouraged learners to think about real-world solutions for reducing energy use and protecting the environment.
The Anton Lembede Mathematics, Science and Technology Academy emerged as the overall winner, earning R60,000 worth of energy-efficiency products for their school. The project stood out for its practical approach to energy saving and for showing how innovation can start in the classroom.
In Johannesburg, City Power hosted its own version of the competition through the Energy Efficiency and Demand Side Management (EEDSM) programme. The initiative focused on public, non-fee-paying high schools and encouraged learners to think about renewable energy and sustainable energy practices.
Sgodiphola Secondary School took first place with a cost-effective solar water heating model, winning R35,000. Seanamarena High School placed second for a short video on household energy conservation, while Jabulani Technical High secured third place with an automated classroom lighting system. The event celebrated creativity and technical skill while showing that meaningful climate action can begin with education.Students also had the chance to win individual prizes such as laptops and bursaries, especially those in Grade 12 who showed interest in pursuing energy-related studies. Both the Durban and Johannesburg competitions reflect how local government initiatives can inspire practical learning, shape environmental awareness, and prepare young South Africans to lead the country’s green transition.
