Author:Leighton, MichaelDate: 2020In South Africa, there is an increasing interest in installing rooftop mounted solar photovoltaic systems. However, financing the photovoltaic systems causes most interest to be abandoned, largely due to the cost required to replace a building's ...Read more
Author:Winkler, Harald; Borchers, Mark; Hughes, Alison; Heinrich, Glen; Visagie, EugeneDate:2005The purpose of this report is to develop some scenarios for Cape Town’s energy future. The simulation model, the Long-Range Energy Alternatives Planning (LEAP) system, has been used to simulate how energy might develop in Cape Town over the ...Read more
Author:Hughes, Alison; Haw, MaryDate:2007The objective of this document is to report on the scenarios considered and compare the costs and social impacts using the sustainability indicators. The scenarios reported on are the energy efficiency improvements in the commercial, industrial, ...Read more
Author:Hughes, Alison; Haw, MaryDate:2007This report is the second of three reports outlining sustainable development pathways for South Africa. It forms part of the reporting for the project entitled “Clean Energy and Development for South Africa” funded by the British Foreign ...Read more
Author:Senatla, MamahlokoDate:2011Energy is a key factor in economic growth and also central to meeting basic socio-economic goals. The use and production of energy in South Africa is associated with greenhouse gas (GHGs) emissions and pollution problems. Gauteng‘s residential ...Read more
Author:Dzenga, BruceDate: 2022Problems in the public policy decision-making environments are typically complex and continuously evolve. In a resource-constrained environment, several alternatives, criteria, and conflicting objectives must be considered. As a result, ...Read more
Author:Hughes, Alison; Haw, Mary; Winkler, Harald; Marquard, Andrew; Merven, BrunoDate:2007Emissions from energy supply and use constitute by far the largest part of South Africa’s total greenhouse gas (GHG) emissions. Hence energy modeling is a key analytical basis for the information provided to the long-term mitigation scenarios ...Read more

Author:Malla, LesegoDate:2011This paper investigates, in the context of Cape Town the emission reduction potential (ERP) of energy from biogas and related cost. Two project-scale models and a city-scale model were developed. Substrates for project model 1 were organic ...Read more
Author:Carolissen, SanchezDate:2018The use of biological waste as a primary energy source for the production of biogas, by the process of anaerobic digestion, has been commonly used in the past by small communities and on a larger scale by waste water treatment plants. In the ...Read more
Author:Davis, Stephen; Cohen, Brett; Hughes, Alison; Durbach, Ian; Nyatsanza, KudakwasheDate:2011The rebound effect is a phrase which was originally defined to refer to the extent to which energy efficiency improvements are lost due to subsequent behavioural changes. This report documents almost three years of research work that set out ...Read more
Author:McCall, BryceDate:2013This work has two main objectives, first to create a working energy model of South Africa’s electricity sector using the open source software; OSeMOSYS, and secondly, using this model to understand the unstudied effects of net metered capacity ...Read more
Author:Tembo, BernardDate:2012Many climate change studies project that occurrence of droughts (due to dry years) in Southern Africa will increase; this raises concerns over Zambia's electricity system. Currently, over 99% of Zambia's electricity is supplied by hydropower, ...Read more
Author:Merven, Bruno; Stone, Adrian; Hughes, Alison; Cohen, BrettDate:2012Transport is a large consumer of energy in South Africa and vital for economic development. Currently the transport sector consumes 28% of final energy, the bulk of which, 97%, is in the form of liquid fuels. As the population grows and becomes ...Read morecb
Author:Winkler, Harald; Haw, Mary; Hughes, AlisonDate:2009Technology learning can make a significant difference to renewable energy as a mitigation option in South Africa’s electricity sector. This article considers scenarios implemented in a Markal energy model used for mitigation analysis. It ...Read more
