This course explores the energy technologies and systems in a framework of enduring social and environmental sustainability on a global scale. We explore alternate energy generation technologies, consumption patterns, and energy efficiency. The emphasis will be on renewable energy generation, energy storage, microgrids, and emerging system operations including smart-grid and demand management. On the consumption side, we focus on buildings and the transportation sector as the main consumers of energy and contributors to greenhouse gas emissions. We examine alternate transportation strategies for sustainability including electrification, hydrogen, and biofuels.
