Changes in energy use patterns in the Bushbuckridge Lowveld of the Limpopo Province, South Africa: eleven years onMadubansi, Mainza January 2004 (has links)
This research reports on the energy transition that has taken place in the Bushbuckridge district between 1991 and 2002. It is a follow up to a similar study that was done in 1991 investigating a number of aspects of energy use. It uses the 1991 study as a baseline and aims to explore how the passage of time, growth of the local population and changes in incomes and the availability of fuels have affected the patterns of fuel use in the region in the past eleven years. A structured interview approach was used for most aspects of the study. The interview schedule included sections on types, amounts and reasons for use and non-use of 13 different energy sources as well as data on income levels, household size and other economic parameters. Analysis of the consumption patterns of the different fuel types revealed that between the two survey periods, households in the sample settlements went through some pronounced changes in patterns of fuel use, particularly those that had acquired electricity. The introduction of electricity in the region had certainly played a major role in spurring the energy transition. Fuels that were previously used for lighting, powering entertainment appliances and refrigeration had been displaced by electricity. In terms of cooking and other thermal application, however, the vast majority of households in all the sample settlements continued using fuelwood and complemented it to a lesser extent with paraffin and electricity. In both surveys, the use or non-use of available fuels in the region was influenced by several factors. Common reasons for non-use of certain fuel types included expense, lack of appliances, the risk involved in using such fuels and the preference for other fuels. Reasons for use were mainly related to the low cost of the fuel and the fuel’s ability to meet particular end uses. Although incomes in the region had increased between 1991 and 2002, they were still below the poverty line. Activities from which households obtained their income remained the same. Old age pension, migrant wages and the informal sector remained the largest contributors of income to most households. Other indicators of relative wealth and poverty, like ownership of vehicles, bicycles and beds remained the same.

Energy utilisation in selected industrial sectors in South AfricaHuggett, Anthony Court January 1986 (has links)
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 in the report "Energy Utilisation in South Africa", published by the Department of Planning and the Environment in 1978. As this report showed the major primary industries to be the largest single users of energy in South Africa, it was decided to isolate a number of major energy-intensive industries for investigation in this study. The 1979 Census of Manufacturing showed five industrial sectors to have consumed 41% by value of the total industrial energy consumption in that year, and it is those with which this thesis is concerned. The five industries are: The Structural Clay Products Industry, The Portland Cement Industry, The Glass Making Industry, The Iron and Steel Industry, The Pulp and Paper Industry.

Investigation of the impact of information on energy consumption at a tertiary institutionMalan, Madeleine 04 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Due to rising energy costs, there is a growing need to reduce energy consumption (limiting greenhouse gas emissions) and reduce electricity demand (as supply capacity is not keeping up with the increased demand), and their resulting financial impact.
This research study investigated the management and reporting of energy consumption at the Stellenbosch University (SU). When considering the three pillars of sustainability (economic, social and environment), the impact of energy usage is high on both financial and natural resources. The research focused on the impact of regular feedback encouraging behavioural change to enable saving of the energy resource, namely electricity, that is becoming more scarce and costly.
The interview results correlated with various studies proving that the context and frequency of updated energy consumption information influence behaviour. Peer networks and pressure also contribute towards an energy-saving attitude.
Certain barriers to energy conservation were identified; these include lack of control experienced by the Faculty Managers over equipment installed, as well as a shortage of capital funding. The main obstacles at the residences are lack of upgrading capital, inadequate feedback relating to energy consumption and improper enforcement of policies regarding the usage of certain equipment in dormitory rooms.
Certain limitations of the study, for example the number of energy meters, made it difficult to prove beyond doubt to what extent feedback influenced the reduced energy consumption. Information campaigns ran parallel with technological interventions, making it difficult to distinguish the impact of each separately. However, it was established that the use of feedback alone would not achieve energy savings to the desired extent.
In conclusion, regular feedback creates awareness, which in turn contributes towards a more energy-conscious culture.

Domestic utilisation of electrical grid energy in South AfricaBeute, Nico January 1993 (has links)
Thesis (PhD (Electrical Engineering))--Potchefstroom University, 1993. / The domestic sector is one of the largest users of nett energy in the RSA
(24%, excluding energy used for transport), but it accounts for only 14% of
the electrical energy used in the RSA.
There is a very strong correlation between the time of the peak of the load
for the domestic sector and the time of the peak of the national load. The
domestic load is the largest contributor to the peak of the national load.
This makes the domestic load more important than is generally realised.
Only limited research has been done about the ways in which domestic
energy is used in South Africa. Developed countries, such as the United
States of America, are continuously engaged in end-use load research, so
they have vast data banks available on domestic end-uses of electricity. Data
on domestic end-use of electricity are urgently needed especially for South
Africa with its very fast growing newly urbanised sector. Since most
energy sources are not replenishable, ways and means must be found to
promote the wise and effective use of all forms of energy. Effective use
of energy can only be promoted if the ways in which electricity is used are
known. In this dissertation the electrical energy requirements of the South African
domestic sector are analyzed for the present situation and for the next few
decades. A model is developed to represent the electrical load. The model
has subsections representing the components of the national domestic electrical load, concentrating on electrical energy for domestic water heating,
with responses to factors such as:
* population growth,
* urbanisation,
* electrification,
* energy efficiency of appliances,
* consumer awareness of energy conservation.
The model is to be used for scenario planning of the electrical grid.
The results of this study will assist to ensure effective planning of the
electrical grid of South Africa into the next century.

Energy management in the South African hotel industryFouejio-Tsobze, Brice January 2010 (has links)
Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2010. / In recent years, the South African hotel industry has experienced increasing demand for hotel's
services. At the same time, mounting costs of energy affects energy performance and public
image. Energy management is a new approach to address those widespread problems. This
study aimed to suggest good management practices and develop a "self-help" approach, to
reduce the demand and costs of energy for the South Africa hotel industry. This is expected to
result in monetary savings and conservation of energy resources. This has been done by
conducting survey within seven selected hotels in Cape Town, metropolitan of South Africa.
In addition, through the "self-help" guide, approaches to energy management system are also
described, showing the ways for hotels to achieve better energy performance. Potentials for
savings from good housekeeping are estimated to 10 - 15%. The "self-help" guide is
recommended to be improved through implementation in pilot hotels; and the proposal set of
benchmarks need to be different for hotels in different provinces of South Africa considering the
differences in climate conditions.
The result of this study range from presenting the energy conservation awareness, barriers,
method of conservation, financial and institution mechanisms, policy measures, status of energy
use and propose strategy to develop a "Self-help" guide for energy management in South
African Hotel industry. It has been found that energy monitoring has been done in the South
African Cape Town hotels. From the total energy consumed by this industry, electricity accounts
80% of it of which air conditioning takes the biggest share (about 50%) and the remaining for
Liquefied Petroleum Gas (LPG), diesel and others fuels. In addition, through the "self-help" guide, approaches to energy management system are also
described, showing the ways for hotels to achieve better energy performance. Potentials for
savings from good housekeeping are estimated to 10 - 15%. The "self-help" guide is
recommended to be improved through implementation in pilot hotels; and the proposal set of
benchmarks need to be different for hotels in different provinces of South Africa considering the
differences in climate conditions.

The value of an energy efficiency strategy : the case for Pioneer FoodsLe Roux, Andries 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2008. / ENGLISH ABSTRACT: This research study explored energy efficiency and the possible implications for a South
African company, the Pioneer Foods Group (Pioneer Foods).
“What value could Pioneer Foods derive from an energy efficiency strategy?” is the
research question posed in this study.
The case study analysis revealed that Pioneer Foods recently listed on the Johannesburg
Stock Exchange and therefore needed to implement an environmental management
strategy as part of their carbon footprint reporting. Energy efficiency turned out to be one
aspect that could have a significant impact on their carbon footprint.
The most important barrier to energy efficiency identified at Pioneer Foods was found to
be the lack of real-time electrical consumption information as this could result in a lack of
ownership taken by mill management. Further barriers included the use of wrong
information for benchmarking purposes as well as a possible misunderstanding of the
different electricity tariffs shown on the electrical utility bill.
Possible ways to overcome the barriers to energy efficiency at Pioneer Foods included
installation of energy meters for real-time monitoring of the energy consumption,
empowerment of people to ensure buy-in, as well as key performance indicators for mill
managers linked to energy efficiency.
It was suggested that the energy efficiency strategy be implemented in stages covering
short-term, medium-term and long-term objectives. This way the implementation process
would seem less intrusive to people and also give the energy efficiency team the
opportunity to learn more and perhaps adjust the strategy throughout the implementation
process.
This research project should act as a starting point for Pioneer Foods to grow from being
unconsciously incompetent to becoming consciously competent in the field of energy
efficiency. The observations made throughout this study, should convince companies that
energy efficiency should not just matter to high energy users. All companies should
explore their own drivers for implementing energy efficiency and act on it. / AFRIKAANSE OPSOMMING: Hierdie navorsingstudie het die effektiewe gebruik van energie, en die moontlike
implikasies vir ‘n Suid Afrikaanse maatskappy, die Pioneer Voedsel Groep (Pioneer
Voedsel) ondersoek.
“Watter waarde sou Pioneer Voedsel kon put uit ‘n energie-effektiwiteit-strategie?”
is die navorsingsvraag wat in hierdie studie gestel is.
Uit die analise blyk dat Pioneer Voedsel onlangs op die Johannesburgse Effektebeurs
genoteer is. Daar word dus van hulle verwag om ‘n omgewingsbestuur-strategie in plek te
stel as deel van hul koolstofvoetspoor-verslaggewing. Dit blyk dat energie-effektiwiteit een
aspek is wat ‘n groot impak op hulle koolstofvoetspoor kan hê.
Die grootste struikelblok tot energie-effektiwiteit by Pioneer Voedsel geïdentifiseer, was die
tekort aan intydse elektriese verbruiksinligting. Dit kan veroorsaak dat die bestuur nie
eienaarskap neem van energie-effektiwiteit nie. Verdere struikelblokke sluit in die gebruik
van foutiewe inligting vir metingsdoeleindes asook ‘n moontlike gebrek aan begrip van die
verskillende elektrisiteitstariewe uiteengesit op die elektrisiteitsrekening.
Moontlike maniere om die struikelblokke by Pioneer Voedsel te oorkom sluit in die
installasie van energiemeters vir intydse monitering van energieverbruik, bemagtiging van
mense om inkoop te verseker, en sleutelprestasie-aanwysers vir bestuurders gekoppel
aan energie-effektiwiteit.
Dit word voorgestel dat die energie-effektiwiteit-strategie in fases geïmplementeer word
om sodoende kort-, medium- en langtermyn-mikpunte te bereik. Sodoende sal die
implementering van die proses minder indringend vir personeel wees. Dit gee ook die
energie-effektiwiteit-span die kans om meer te leer asook die strategie aan te pas soos
nodig tydens die implementeringsproses.
Hierde navorsingsprojek moet dien as die vertrekpunt vir Pioneer Voedsel om te groei van
onwetend onbekwaam tot wetend bekwaam in die veld van energie-effektiwiteit. Verder
behoort dit maatskappye te oortuig dat energie-effektiwiteit nie net ‘n verskil maak vir hoë
energie verbruikers nie, maar dat alle maatskappye hulle eie drywers vir die implementering van energie-effektiwiteit behoort te identifiseer en daarvolgens
aksiestappe te neem.

Residential customer acceptance and response to time-of-use electricity tariffs18 March 2015 (has links)
M.Com. (Business Management) / The residential demand profile for electricity shows that this segment of the market has. a great demand in the morning and early evening. Due to a shortage of generation capacity during these peak consumption periods, different strategies are now needed to persuade customers to use their electricity in the periods when there is not a great demand. One way in which this can be achieved is to give the customers a time differentiated tariff i.e. a time-of-use (TOU) tariff, whereby the customer will pay a high energy rate in the peak periods, and lower energy rates in the off-peak and standard periods. The overall goal of this study was to determine to what extent residential customers would respond to such a tariff The study covered three consumption groups i.e. customers using more than 1500 kWh per month, between 600 and 1000 kWh per month, and between 300 and 600 kWh per month. All the customers taking part in the study were direct Eskom customers. Once the customers had agreed to participate in the study, they had TOU measuring equipment installed in their homes, which measured their consumption according to the time of day it was consumed.

Regulation of energy efficiency by voluntary agreement : South Africa's energy efficiency accord.Jackson, Thomas. January 2008 (has links)
Energy efficiency is an issue currently generating huge interest as a potentially costeffective
solution to the twin challenges of environmental pollution from energy production,
and the increasing scarcity of energy resources. This research aims to interrogate the
practicalities of regulation of energy efficiency to ask what scope there is for public-led
encouragement of greater energy savings in industry. Shortcomings of current theory
addressed include a discounting of the impact of heterogeneity of industrial activity on
prospects to effectively regulate for energy efficiency, and a conflation of the different
aspects of societal functioning to which energy efficiency regulations and incentives can
be applied. The research argues that the scope for energy savings has been exaggerated
and the factors which drive pursuit of energy efficiency within firms of different sizes poorly
understood and articulated. The Voluntary Agreement form of environmental regulation is
assessed for its applicability to regulating for energy efficiency in the context of these
characteristics of energy efficiency in industrial settings. An in-depth interview approach
with core participants in an example of a Voluntary Agreement for energy efficiency in
South Africa, the Energy Efficiency Accord (Accord), reveals the difficulties of regulating
for specific technologies, the generally targeted nature of energy efficiency incentive
schemes which provide household and commercial-type programmes to heavy industry,
and the fact that environmental objectives and capacities are highly developed within firms
interviewed and in most cases precede participation in Accord activities. The inference is
that participation at this stage of the Accord's existence is driven by the need to develop
and maintain relations between key stakeholders, and to exploit opportunities to influence
the form of energy efficiency regulation enacted as opposed to the need to obtain forms of
technical guidance. The particular pattern of participation in the Accord is argued to result
in part from the historical dominance of large, energy-intensive firms in South Africa, and
to be consistent with the theory that the more energy-intensive firms in a society will be
motivated to participate in voluntary initiatives such as the Accord. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2008.

Spesifieke verbruik van steenkool in die Suid-Afrikaanse energie-ekonomie met spesiale verwysing na die invloed van hoër steenkoolpryseVan Rooyen, Gerhardus Christiaan 15 September 2014 (has links)
M.Phil. / Coal is today providing more than seventy-five percent of South Africa's energy requirements and will, to a large extent, remain so in the future. It is thus important to evaluate the adequacy of the country's available coal resources against expected future demand. The main objective of this study, which was done under the supervision of Prof. D. J. Kotze, was therefore to analyse the specific consumption of coal in the various consumption sectors in order to establish historical trends. The specific comsumption of coal is defined as the amount of coal used to produce a unit of final product. The factors attributing to these observed trends were determined and their future role evaluated in order to establish whether it was possible to extrapolate historical trends into the future. By means of curve fitting to the observed data and extrapolation it was possible to obtain future values of specific coal consumption for each of the sectors. These values, together with the production output forecasts for the various sectors were then used to calculate the total coal requirements for three reference years, namely, 1990, 1995 and 2000. The role of coal prices in explaining trends in specific coal consumption of various sectors was also analised separately. Information to conduct the study was obtained mainly from the various coal producers' associations as well as from individual producers and other organizations such as Escom, Sasol and Iscor, the Department of Hineral and Energy Affairs and the Hinerals Bureau. In some instances private firms and producers' associations were also consulted as well as a wide variety of literature on the subject. The principal finding of the study was that coal was substituted or was still being substituted by electricity in most final applications because of the convenience of use. Coal, however, still plays and probably will continue to play an important role in future in basic industries such as the metallurgical industry. Coal prices have not up to now played a very important role in the overall specific consumption of coal which can probably be attributed to the relatively low prices of coal on the inland market. It was also found that it was not desirable to do away with the present system of price control entirely as a certain measure of control was still necessary to safeguard the usuage of coal in certain applications for which there were no other substitutes. It was further concluded that South Africa does not have the vast quantities of coal commonly thought and that measures have to be taken in order to ensure that the country's coal resources are conserved and that optimum use is made of available resources.
