RETTI was established to train, mentor, and provide work experience for youths who will drive the energy transition as skilled workers for the renewable energy industry and as entrepreneurs who directly deploy clean energy solutions. We equip clean energy technicians, developers, engineers, and employees. Research has shown the gap in the technical know-how of renewable energy engineers and handsmen. If people are trained on proper renewable energy technology design, its applications, and entrepreneurship, it will promote environmental sustainability and improve the economy through the creation of jobs.
