In Minas Gerais, the 2026 National Energy Efficiency Olympiad (ONEE) has opened registrations for elementary and high school students to promote conscious electricity consumption. Additionally, Belo Horizonte has enacted Law 12.103/2026, which allows municipal schools to produce their own electricity via solar photovoltaic systems, prioritizing areas with high social vulnerability. On a national scale, the 5th National Energy Efficiency Olympiad, organized by the Agência Nacional de Energia Elétrica, aims to engage approximately 660,000 participants through pedagogical activities. Alongside these efforts, the Shell Eco-marathon is marking ten years in Brazil, hosting over 500 students from various Latin American countries in Rio de Janeiro to compete with ultra-efficient vehicle prototypes powered by electric, hydrogen, or internal combustion technologies. ## Timeline ### 2026-08-21: Brazil hosts energy efficiency and sustainable mobility competitions Brazil hosts major energy efficiency events, including the National Energy Efficiency Olympiad for students and the 10th anniversary of the Shell Eco-marathon in Rio de Janeiro. 2 sources. https://clstr.news/cluster/brazil-hosts-energy-efficiency-and-sustainable-mobility-competitions ### 2026-08-18: Minas Gerais initiatives promote energy efficiency and solar power Minas Gerais students can compete in a national energy efficiency olympiad for prizes, while Belo Horizonte implements a law to install solar panels in municipal schools. 2 sources. https://clstr.news/cluster/minas-gerais-initiatives-promote-energy-efficiency-and-solar-power --- Cite as: Energy efficiency and sustainability initiatives in Brazil.
