Application of photovoltaic solar energy to medium-scale installations

Author: Bezuidenhout, Sandra Date: 2001 Although South Africa has significant energy reserves, some 50-60% of the South African population is without access to electricity. Lack of infrastructure is one of the root courses of which energy supply forms an important component. The ... Read more
Coal demand for electricity generation in South Africa : analysis and conditional forecasts to the year 2020

Author: Pouris, Anastassios Date: 1987 The purpose of this thesis is to provide an analytical framework for the examination of the demand for coal for the generation of electricity where more than 50 of the coal produced in the country is consumed. More specifically, the aim of ... Read more
A decision making tool for assessing grid electrification versus stand-alone power supply options for remote users

Author: Borchers, Mark Louis Date: 1989 The objective of this study is to compile a micro-computer based tool to aid in the evaluation of power supply options for remote sites. The options considered are stand-alone photovoltaic, diesel generation, and grid extension power supplies. ... Read more
The effect of altitude on the performance of a spark ignition engine using an alcohol-blended fuel

Author: Wong, Ching Tai Date: 1996 It is known that altitude influences both the performance and octane requirement of automotive engines. With the peculiar elevated geography in South Africa, there has been concern of the effects of altitude on automotive engines, when driving ... Read more
The effect of sulphur in fuel on the performance of automotive catalysts

Author: Siemelink, Johannes Jacobus Date: 1994 Catalysts have been used on cars since 1974 to reduce tailpipe emission levels of carbon monoxide, hydrocarbons and oxides of nitrogen. Initially, oxidation catalysts were used that operated under very lean air/fuel conditions and gave rise ... Read more
Emissions and efficiencies of domestic appliances burning various fuels in South Africa

Author: Graham, James Alexander Norman Date: 1998 Assessments of pollution from domestic fuel burning in South Africa have, in the main, based their conclusions on measured ambient pollutant concentrations. This approach does not allow for direct comparison of emissions from different domestic ... Read more
Energy efficiency in the South African clay brick industry

Author: Hibberd, Andrew Charles Michael Date: 1996 This report presents the results of an energy study carried out on the clay brick industry of South Africa. The clay brick industry consumed approximately 38 PJ of energy in 1995, about 5% of manufacturing energy consumptions and had an energy ... Read more

Author: Gielink, Michael Ian Date: 1992 In this thesis the energy sector of the East and Southern Africa Region (as defined by the World Energy Council) is investigated. Special attention is given to South Africa and the potential future role she could play in the region. The region ... Read more
Energy management in industry : a case study on the brewing industry

Author: De Villiers, Mark Graham Date: 1992 The industrial sector is the main energy user in South Africa, using about half the national total, and compared to most other industrialised countries South Africa has a high in_dustrial energy intensity, thus necessitating improved industrial ... Read more
An energy supply and demand model for South Africa

Author: Silberberg, Roger Barry Date: 1981 The topic of this thesis is the development of a model of energy supply and demand in South Africa to project energy flows up to the year 2005 and also to assess the implications of policy actions. South Africa in the 1980's will be faced by ... Read more
Energy utilisation in selected industrial sectors in South Africa

Author: Huggett, Anthony Court Date: 1986 This thesis presents tha findings of an investigation into the use of energy, between the years 1975 and 1984, in five of the major energy-intensive industries in South Africa. Energy use in all economic sectors, from 1964 to 1974, was surveyed ... Read more
