The need to transition to new and cleaner forms of energy has never been more imperative in the face of climate change. At the same time, the twin pressures from increasing global demand for energy and the scarcity of critical materials needed for new energy technologies impose additional challenges in making the transition to clean energy sources. In this workshop, we will explore how theory, modeling, and experiment are rising to the challenge of designing inexpensive, earth-abundant materials to enable the next generation of clean energy technologies. The goals of this workshop are: 1) to integrate concepts from chemistry, physics and engineering for materials design, and 2) explore through hands-on activities how alternative clean energy sources can be utilized in day-to-day applications.
