|dc.description.abstract||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,
* 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.||en_US
