- W3177342708 abstract "This thesis focuses on the interplay between dynamic economic policies concerning the use and preservation of natural resources and the technological, environmental and geographical frameworks in which they are implemented. The first chapter proposes an analysis of optimal peak load decarbonation pathways when back-up fossil fuels are being gradually substituted by stored intermittent renewable energy. We model the process of intermittent renewable energy storage under renewable energy surplus uncertainty in a Markovian framework and consider technical progress in both storage efficiency and capacity. This allows us to study the optimal storage policies with respect to carbon and storage costs, as well as the renewable energy surplus distribution. We analytically solve this problem under specific assumptions and use a value function iteration algorithm to investigate numerically on the optimal energy storage policies for peak load decarbonation in Portugal. Along with intermittency and storage costs, land use is another limitation to the development of renewable energy. In the second chapter of this thesis, we develop a macrodynamic growth model of the energy shift integrating land use constraints. Land is considered as a resource for agricultural production along with energy. Developing renewable energy uses space and thus interferes with the agricultural sector. Moreover, pollution abatement policies, such as forests preservation policies, also compete with renewable energy for land in order to reduce pollution from the use of fossil fuels. We theoretically study the competition in land use between agriculture, pollution abatement and renewable energy production and apply our model to study the development of a palm oil biodiesel sector in Brazil, along with the issues it rises regarding the Amazon forest preservation. The last chapter of this thesis also focuses on agricultural land, but this time to assess the impact of the agriculture activity on soil fertility. More precisely, we focus our analysis on a specific externality from the agricultural sector being diffuse soil pollution. Hence, we develop in this chapter a spatial growth model for an agricultural economy, in which pollution diffuses across space. We analytically show that, due to diffuse soil pollution, the economy can reach a long-term spatial equilibrium with a fertile region and a polluted region, and that the polluted region can either stagnate at low levels of fertility, or catch up with the fertile region. Our results are numerically illustrated, including the resiliency of the economy to recover from pollution shocks." @default.
