Primary Energy: Renewable Fuels
Wind, solar, and biomass energy are modeled explicitly in the FeliX model. Investment in and development of these energy sources is calibrated to the results of IIASA's Global Energy Assessment (2012) for RCP 6.0. As shown below, future development of renewable energies--especially solar & biomass--shows strong dependence on population growth. In the case of biomass, this dependence has important consequences for land use change: specifically, forest degradation.
