As we learn about the physical mechanisms of global warming, it is important that you start thinking about how to tackle the energy crisis in order to prevent further warming. First, please watch the NOVA documentary “Power Surge”, which is based on a pa.per that was published in Science by Pacala and Soccolow (2004). Then, watch the video focused on California’s renewable energy problems. In this discussion, based on what you learned in/outside of this class, please list at least three of the most promising future renewable energies (i.e. three wedges) to minimize our carbon footprint dramatically and reach the goal of zero emissions. In order to reach this goal, what do we need to develop further? Please elaborate on this in your discussion based on what you learned. Due by April 24th.
