Overview of technology challenges and opportunities for energy in the context of global warming. Physics of greenhouse warming, projected climate changes, and structure of US and global energy economy are reviewed. Majority of lectures emphasize understanding engineering and economics of low-carbon energy production systems, including solar, wind, nuclear fission, and capture/storage of fossil-fuel carbon. Energy storage and efficient energy use are also considered. Intersections of energy with economic development, international security, local environmental quality, and human behavior are also touched upon.
