Determining the impacts of selected energy policies on Gauteng's residential energy consumption and the associated emissions using LEAP as a tool for analysis : implications for sustainable livelihoods for the poor
… Africa is associated with greenhouse gas (GHGs) emissions and pollution problems. Gauteng‘s residential sector is faced with a slowing rate of electrification due to high in-migration rates and high pollution levels in households that use coal to meet their energy needs. This study analyses …

Local variation and regional transport of tropospheric ozone over Cape Town
… likely to be associated with photochemical pollutants such as tropospheric ozone (O3) and some of its precursors. Previous studies have identified local emission sources and meteorological conditions associated with both the air pollution and the brown haze in Cape Town. However, due to the …

Aplicação de controle preditivo não linear multivariável com otimizador à operação transiente de turbina a gás
… to minimize fuel consumption and pollutant emissions. The inherent optimization process of the controller is solved and verified by means of three evolutionary algorithms and one direct search method. The proposed controller is successfully applied to the simulated gas turbine for load fall …

Emission quantification associated with firewood usage: A case study of Mangondi village in Limpopo Province, South Africa.
… hence, this results in high air pollutant emissions since the fuelwood is not fully combusted. A large quantity of criteria pollutants and greenhouse gas (GHG) are present in the atmosphere causing global warming and climate change due to domestic wood combustion (DWC). The aim of this …

Emission quantification associated with firewood usage: A case study of Mangondi village in Limpopo Province, South Africa
… hence, resulting in increased smoke and gaseous emissions since the firewood is not fully combusted. A large quantity of criteria pollutants and greenhouse gas (GHG) are released to the atmosphere from such combustion which potentially contributes to global warming and climate change. The aim of …
