The global effects of climate change associated with the reliance on fossil fuels for our energy needs are among some of the most challenging problems facing the world today. In this course, students will develop an understanding of the physical principles behind the greenhouse effect and the observational evidence for its existence. They will investigate the scientific principles relevant to energy and energy resources, including aspects such as thermal, nuclear, solar, wind and hydroelectric power generation. The prospects and challenges for a transition away from fossil fuels will be evaluated. This course is suitable for any student interested knowing more about the science of climate change and the possible routes for a transition to an emissions free energy sector.
