“…Among the practitioners of the IDA method there are differences concerning the appropriate indexing method. We, however, concur with Mendiluce et al [19], Ang and Liu [6], Ang [26] and Ang and Zhang [27] Another feature of the LMDI decomposition method is that it presents symmetry between decomposition of changes in terms of ratios or differences [28], which means that decomposition in ratios or differences conclude the same results. Given the above rationale, and the international support for, we also use the LMDI method in the same way as Zhao et al [20].…”

“…The decomposition of energy (sic. electricity) consumption is not unlike the use of indices to investigate the contribution of changes in quantity and price to changes in aggregate consumption [19]. Decomposition analysis is employed to separate changes in electricity consumption over time into mainly three driving factors, namely i) changes in the structure of the economy, ii) changes in efficiency and/or iii) production changes [3,4,5,6,7].…”

“…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.…”

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.

The Water Framework Directive defines common objectives for water resources throughout the European Union (EU). Given this general approach to water preservation and water policy, the objective of this paper is to analyse whether common patterns of water consumption exist within Europe. In particular, our study uses two methods to reveal the reasons behind sectoral water use in all EU countries. The first method is based on an accounting indicator that calculates the water intensity of an economy as the sum of sectoral water intensities. The second method is a subsystem input-output model that divides total water use into different income channels within the production system. The application uses data from the year 2005 on water consumption in the production system of the 27 countries of the EU.From our analysis it emerges that EU countries are characterized by very different patterns of water consumption. Mediterranean and central/eastern European countries use water mainly for agriculture whereas northern European countries use it mainly for electricity, gas and water supply.In most countries, the water used by the fuel, power and water sector is consumed to satisfy domestic final demand. However, our analysis shows that for some countries exports from this sector are an important driver of water consumption. Focusing on the agricultural sector, the decomposition analysis suggests that water usage in Mediterranean countries is mainly driven by final demand for, and exports of, agricultural products, whereas domestic final demand is the main driver of water consumption in central/eastern European countries.Given these heterogeneous water consumption patterns, our analysis suggests that Mediterranean and central/eastern European countries should adopt specific water policies if water consumption in the European Union is to be efficient.JEL codes: N5; C67
