Wind, solar, and biomass/biofuels are three of the most prominent renewable energy sources and the use of these resources is expected to continue growing over the next several decades. What are the key advantages associated with each of these energy sources in terms of a transition away from our current fossil fuel-based economy? (Provide at least two “advantages” for each of these alternative energy sources.) Next, discuss key challenges that historically have made fossil fuels more economically and technologically competitive than these alternative energy sources. Finally, describe a plausible scenario for an electric power grid in DeLand, FL, that is entirely run by some mixture of wind, solar, and biomass energy in the year 2050. Use plausible evidence/arguments from your text, lectures, and other supplementary materials to construct this scenario. (25 points)
