Introduction
The Brazilian Land Use and Energy Systems (BLUES) model is a perfect-foresight, least-cost optimization model for Brazil. It chooses the energy and land-use system configuration with the least total system cost over the entire time horizon of the study, in this case from 2020 to 2060. The model minimizes costs of the entire energy system, including electricity generation, agriculture, industry, transport and the buildings sectors. BLUES finds optimized mixes for the energy system as a whole, rather than evaluating sectorial optimal solutions. It includes CO2, CH4 and N2O emissions associated with land use, agriculture and livestock, fugitive emissions, fuel combustion, industrial processes and waste treatment.
BLUES has five native regions, plus an main overarching region. Its five sub-regions are nested following the macro-geopolitical division of the country. The energy system is represented in detail across sectors, with over 2000 technologies available in and customized for each of its native regions. The representation of the land-use system includes forests, savannas, low- and high-capacity pastures, integrated systems, cropland, double cropping, planted forests, and protected areas. Cropland is made up of Land useis also regionalized and customized for each subregion, with yields and costs varying from region to region. Demand is exogenous but endogenous energy efficiency measures permit demand responses through technological options.
