It has been scientifically clear for some time that the global community must decarbonize the energy and material system entirely by mid-century. In additional recent energy future scenarios have highlighted the pathways to reach this dramatic decarbonization objective on household to village to national and regional levels. The short -- few decade -- time needed for this transition demands a rapid scale- up on current and near-term technologies, while the long-term complete energy sector transition opens the door for an innovation and industrial transformation program. In this talk both the near- and long-term energy vision will be explored in the context of a clean energy economy, and the social and equity implications.
