The Clean Tech Competition is a unique, worldwide research and design challenge for pre-college youth. The program encourages scientific understanding of real-world issues and the integration of environmentally responsible energy sources. Each year, the Clean Tech Competition addresses an issue that is grounded in core technological competency areas and focuses on the next great engineering challenges. The competition is designed to foster a deeper understanding of STEM (science, technology, engineering, and math) related concepts, recognize outstanding talent, and prepare the next generation of globally competitive innovators.

The Clean Tech Competition is a program of the Center for Science Teaching & Learning (CSTL).
