“…The most commonly used were various cointegration techniques (Inglesi, 2010;Ziramba, 2008;Amusa et al 2009). However, there were two studies identified that tried to unfold the factors affecting changes in energy and electricity consumption by using decomposition methods (Inglesi-Lotz and Pouris, 2011;. The overall results showed that changes in the structure of the economy as well as changes in the efficiency that the country uses energy (electricity) play an important role in the trend of energy usage.…”

The purpose of this paper is to review, summarize, and critically assess the academic studies that have dealt with either the causal relationship between energy consumption and growth or the determinants of energy demand in South Africa from 2007 and outline recent forecasts for electricity demand. The results of this review aim to identify gaps in the existing research. From a policy point of view, the findings of this effort have the potential to inform the relevant stakeholders to make appropriate interventions to improve the status quo of the energy sector. The results have indicated that studies examining the causality direction between energy (electricity) consumption and economic growth have failed to reach a consensus. The main differences identified were the time periods examined, the econometric approaches, and the variables included in the estimations. Another potential reason for the results is the availabilityor lack thereof-of data specific for the country. On the other side, the studies looking at the factor affecting energy (electricity) demand have agreed that economic growth or income or output are considered significant factors. The role of prices was debatable among different studies. This has become more apparent when reviewing the few forecasting efforts in the country that resulted in conflicting results.

“…Further, the industrial sector has been shown to have a high-energy-intensity character [3]. From this it is clear that some industrial firms do not readily adopt EE technologies to help reduce their intensity profile.…”

Preliminary investigations into the energy efficiency of manufacturing firms operating in South Africa have shown that no previous study of the barriers to energy efficiency has been conducted. This paper sets out to investigate whether there is an energy efficiency gap in medium to large manufacturing firms operating in the eThekwini municipal area. It goes on further to analyse the barriers to energy efficiency in such firms. These barriers are analysed by firm characteristics and across manufacturing sectors. The findings of this research indicate that more can be done to improve the energy efficiency profile within South African manufacturing subsectors. Policy-makers should take these findings into consideration when drafting new policy on energy efficiency. OPSOMMINGVoorlopige ondersoeke oor energiedoeltreffendheid in vervaardigingsaktiwiteite van maatskappye in Suid-Afrika toon dat daar geen vorige studies bestaan wat fokus op die struikelblokke van toepassing op bestaande energiedoeltreffendheid nie. Hierdie artikel ondersoek 'n energiedoeltreffendheidsgaping wat bestaan binne medium tot groot vervaardigingsmaatskappye binne die eThekwini munisipale gebied. Die ondersoek identifiseer en analiseer gepaardgaande beperkinge wat bestuurders binne sulke maatskappye verhinder om energie doeltreffendheid te implementeer. Die ondersoek en analise strek oor 'n aantal vervaardigingsektore. Die bevindinge van hierdie navorsing dui daarop dat heelwat meer bereik kan word in terme van energiedoeltreffendheid binne die verskeie vervaardigingsubsektore in Suid-Afrika. Hierdie gevolgtrekkings behoort in ag geneem te word deur beleidmakers tydens die opstel van 'n nuwe beleid oor energiedoeltreffendheid.

Abstract:Energy supply security is a significant part of China's security, directly influencing national security and economic and social sustainability. To ensure both China's present and the future energy supply, it is essential to evaluate and forecast the energy supply level. However, forecasting the energy supply security level is difficult because energy supply security is dynamic, many factors affect it and there is a lack of accurate and comprehensive data. Therefore, based on previous studies and according to the characteristics of energy supply and the social development of China, first, the authors apply a comprehensive evaluation method to quantify the energy supply security. Second, based on the ARIMA-XGBoost hybrid model, the authors create two novel approaches for forecasting the energy supply security level of China. The authors find that: (1) energy supply security is dynamic, and green development has become the theme of China's energy development. The energy industry urgently needs to provide more high-quality ecological energy products to meet the people's desire for a beautiful ecological environment; (2) since the mean absolute percentage errors are below 4.5% when forecasting the energy supply security indicators, the ARIMA-XGBoost hybrid model is more accurate for forecasting China's energy supply security level and (3) the security level of China's energy supply has developed periodic features; the ESSI can improve by about 0.2 every five years, but, due to the low starting point and multiple types of constraints, it is difficult to reach the safety level in a short time.
