“…Decomposition techniques have become a useful tool for energy modelling and analysis over the last two decades with special focus on energy consumption and efficiency [4,11,14,18,19,20,21,22,23,24] as well as carbon emissions [25,26,27,28,29,30] or both energy intensity and emission intensity [31]. For South Africa, Inglesi-Lotz and Blignaut (2011) have used decomposition techniques to examine the factors that affected electricity consumption in the economy-wide and sectoral level.…”

“…In the literature, a number of studies [4,14,35] employed decomposition techniques to separate changes in energy consumption into mainly three driving factors: (i) changes in economic structure, (ii) efficiency and (iii) production. Many studies also recently used decomposition techniques to unfold the determinants of emissions' trends in countries [25,26,27].…”

Improvement of energy efficiency has been accepted as one of the most cost-effective approaches towards sustainable economic development and reduction of the continuously increasing energy consumption internationally. South Africa, being among the developing countries, is not an exception even though historically low energy prices and the lack of appropriate policies have created an energy-intensive economy. This paper examines the factors affecting the trends in energy efficiency in South Africa from 1993 to 2006 and particularly the impact of structural changes and utilisation efficiency of the country's energy intensity. Identifying and understanding the driving forces are necessary ingredients in the development of appropriate policy-making. This paper also provides disaggregation of the energy efficiency trends in the main sectors of the economy.We determine that structural changes of the economy have played an important and negative role in the increasing economy-wide energy efficiency. On the other hand, the energy usage's intensity was a contributing factor to the decreasing trend of energy efficiency. We suggest that differentiated price policies may be required if South Africa is to create an effective energy efficiency policy.

“…In order to calculate the targeted indicator for the specific application, we define electricity intensity as the electricity consumption (total or per sector) divided by the Gross Domestic Product (GDP) (overall economy or sectoral [20,21] One part of this exercise would be to compare the South African data with the OECD countries that were selected as the benchmark. Information for total and sectoral electricity consumption was derived from the Energy Balances for OECD countries [22] and Energy Balances for non-OECD countries [23].…”

“…In the past, a large number of studies were conducted to identify the dynamics, determinants and characteristics of electricity intensity in both developed and developing economies [3,4,5,6]. From these studies it is derived that electricity intensity first increases as a consequence of rising economic growth and development, but subsequently falls as a result of a shift to a services-based economic structure [7].…”

This paper investigates the relationship between South Africa's total electricity intensity and that of the OECD members, a very important trade block. These results will assist in ascertaining possible scope for improvement, if such exists. This is necessary as electricity is an essential input for production, and hence it affects the competitiveness of the country.Calculating the electricity intensities, defined as the ratio of electricity consumption to total output, we found that South Africa's electricity intensity more than doubled between 1990 and 2007.All the OECD members' (excluding Iceland) weighted growth in electricity intensity was lower than that of South Africa by a considerable margin. The sectoral analysis showed that the majority of the South African sectors are more electricity intensive.To improve its industrial competitiveness and, as an additional benefit, contribute towards achieving its stated commitments to the reduction of greenhouse gas emissions, South Africa will have to improve its total and sectoral electricity efficiency levels, that not only were higher but also increasing at an alarming rate.
