This course intends to help the undergraduates to have a deep thinking on the relationships between energy and social development, to learn necessary fundamental knowledge and methods of energy engineering and technology, to have a broad view on the advanced energy conversion technologies, and to understand the characteristics and application prospect of typical fossil energy sources and new energy sources. This course intends to lead the future leaders into the field of energy technology with a broad and functional perspective and without constraints by disciplinary boundaries. The experiences of using analytical, experimental and computational tools might help them competent for analysis, design and optimization of different energy systems.
