The challenge of transforming entire economies is enormous; even more so if a country is as fossil fuel based and emission intensive as South Africa. However, in an increasingly carbon constrained world and already now facing climate change impacts South Africa has to reduce greenhouse gas emissions intensity soon and decidedly. The South African electricity sector is a vital part of the economy and at the same time contributes most to the emissions problem. First steps have been taken by the South African government to enhance energy efficiency and promote renewable energy, however, they fail to show large-scale effects. This paper seeks to identify the relevant barriers to renewable energy investments and, based on experience from other countries, provide policy recommendations. 相似文献

Integrated resource planning (IRP) of power generation and delivery characterized by higher penetration of distributed energy resources (DERs) has taken the 21st century world by storm. It promises power markets that are more resilient to resource and capital cost uncertainties as well as environmental sustainability. The success of this new paradigm has been largely anchored by decisive support policy mechanisms and good implementation. But while the developed and emerging economies are registering phenomenal growth in their renewable energy industries, South Africa would appear to be caught in a time warp with a weak environment policy and a power sector that continues to plan its future in the traditional way. The consequences are continued environmental degradation and a high-energy intensive economy with intermittent power supplies. 相似文献

Renewable energy usage in Africa has been reviewed using South Africa, Egypt, Nigeria and Mali as case studies. The various national energy policies of these countries were analysed and areas that require attention to achieve sustainability were highlighted. On the overall, the success of sustainable development in Africa lies in addressing the imminent energy crisis in the continent. Excessive usage of fuel wood is already creating considerable environmental problems especially in the Sahel. Africa has all the potentials to solve its energy problems if appropriate infrastructural support can be provided for harnessing the abundant renewable resources in the continent, and if skills are pooled together and experiences shared in addressing the key issues. 相似文献

Energy efficiency is one of the most potent and cost effective ways of meeting the demands of sustainable development. It has in fact been referred to as the best energy resource. Way back in 2005 the South African Department of Minerals and Energy (DME) published its Energy Efficiency Strategy in support of some of the objectives enlisted in the 1998 White Paper on Energy Policy. The Strategy set a national target for energy efficiency improvement of 12% by 2015 against the baseline year 2000. The document further predicted that, with a business as usual model of energy usage, at the projected rate of national economic development, there would be a need to invest in new power generating capacity by around 2007. Despite the policy foresight and seemingly enthusiastic efforts, though, the dawn of 2008 saw the country gripped in an electric power crisis, with a capacity shortfall of over 10%. This paper looks at what could have gone wrong, examines energy efficiency policies and measures in other countries and how these lessons could be adopted to the South African context. 相似文献

Battery charging and water pumping has been the only applications for wind energy in South Africa till now. A conservative estimate of the wind resource indicates that approximately 5% to 6% of the South African energy demands can be supplied from wind. However the low cost of electricity due to the abundance of cheap coal has made it difficult to justify the use of grid connected wind turbines. As with other countries where wind energy is now a part of the total energy package, South Africa will also have to go through a process of wind energy having to prove itself as a viable option while at the same time have a cost disadvantage. 相似文献

South Africa has an ideal climate for low energy building, but also has a well established coal industry contributing to very cheap electricity. The energy intensity is high with a substantial proportion being used to render buildings habitable in an ideal climate for passive design. Coal is largely used for space heating leading to severe pollution. A new housing drive offers an ideal opportunity to address the neglected area of low energy in South African housing. Dramatic energy savings and peak demand reductions have been modelled and proven experimentally. 相似文献

The South African energy debate is and will remain a heated one. Given South Africa's history of racial inequality and contemporary concerns around sustainability, much of it rightly focuses on the links between energy, poverty and the environment. Yet, many contributions to the (mainstream) debate seem to have a somewhat one-sided focus that might hamper rather than stimulate the understanding of these links. They either display a strong technical, quantitative bias and/or lean towards rather simplistic ideas about policy processes and dynamics. The article argues that many of these analyses could benefit greatly from a critical focus on the political economy of energy: the political–economic power structures that influence both many energy policies and the issues of energy equality and sustainability. Two major global developments emphasise the importance of this focus: the recent financial crisis and South Africa's role in the increasingly tense geopolitics of energy in Africa. The article concludes with some suggestions on how currently disparate political economies of energy could be better connected. 相似文献

Renewable energy remains a contested topic in South Africa. This paper argues that South Africa can build on the momentum surrounding its introduction of a feed-in tariff by enacting policies that may, if given adequate funding and political effort, allow the country to be a world leader in renewable energy. Given a variety of renewable energy policy options for moving forward, a majority of stakeholders consulted in this study strongly prefer the development of a renewable energy manufacturing cluster, in which government develops coordinated policy mechanisms that attract renewable energy manufacturers, over three other policies suggested by the authors. Interviews with key informants that play critical roles in this decision-making process suggest that there are reasons to remain cautiously optimistic about the country's renewable energy future while cognizant of the challenges that must still be overcome. Opportunities for a low carbon renewable energy transition in South Africa include the prevalence of broad stakeholder consultation, facilitated by civil society, and an innovative policy development context. Significant impediments also exist, however, and include pervasive social issues such as poverty and political inertia, along with the ongoing difficulties facing renewable energy technologies in reaching grid parity with inexpensive and abundant South African coal. 相似文献

Emerging nations are typically characterised by highenergy intensities despite significant energy efficiency potentials and numerous project oriented efforts to introduce energy-efficient technologies. The paper argues that successful technology dissemination needs appropriate institutional structures to reduce the related transaction cost. While a project-by-project approach risks to evaporate after completion, an energy agency would allow to bundle the know-how and information gained, ease access to funding and thus reduce information search cost and increase availability of efficient technologies. In a case study for South Africa, we examine the appropriateness of this concept for emerging nations. We discuss the underlying incentive problem from a new institutional economics perspective and suggest an approach to the design and implementation of operable energy agencies. 相似文献

Electricity consumption and economic growth in South Africa: A trivariate causality test 总被引:2,自引:0,他引:2
In this paper we examine the causal relationship between electricity consumption and economic growth in South Africa. We incorporate the employment rate as an intermittent variable in the bivariate model between electricity consumption and economic growth—thereby creating a simple trivariate causality framework. Our empirical results show that there is a distinct bidirectional causality between electricity consumption and economic growth in South Africa. In addition, the results show that employment in South Africa Granger-causes economic growth. The results apply irrespective of whether the causality is estimated in the short-run or in the long-run formulation. The study, therefore, recommends that policies geared towards the expansion of the electricity infrastructure should be intensified in South Africa in order to cope with the increasing demand exerted by the country's strong economic growth and rapid industrialisation programme. This will certainly enable the country to avoid unprecedented power outages similar to those experienced in the country in mid-January 2008. 相似文献

This paper examines the demand for imported crude oil in South Africa as a function of real income and the price of crude oil over the period 1980–2006. We carried out the Johansen co integration multivariate analysis to determine the long-run income and price elasticities. A unique long-run cointegration relationship exists between crude oil imports and the explanatory variables. The short-run dynamics are estimated by specifying a general error correction model. The estimated long-run price and income elasticities of −0.147 and 0.429 suggest that import demand for crude oil is price and income inelastic. There is also evidence of unidirectional long-run causality running from real GDP to crude oil imports. 相似文献

In 2008, South Africa experienced a severe electricity crisis. Domestic and industrial electricity users had to suffer from black outs all over the country. It is argued that partially the reason was the lack of research on energy, locally. However, Eskom argues that the lack of capacity can only be solved by building new power plants.The objective of this study is to specify the variables that explain the electricity demand in South Africa and to forecast electricity demand by creating a model using the Engle–Granger methodology for co-integration and Error Correction models. By producing reliable results, this study will make a significant contribution that will improve the status quo of energy research in South Africa.The findings indicate that there is a long run relationship between electricity consumption and price as well as economic growth/income. The last few years in South Africa, price elasticity was rarely taken into account because of the low and decreasing prices in the past. The short-run dynamics of the system are affected by population growth, tooAfter the energy crisis, Eskom, the national electricity supplier, is in search for substantial funding in order to build new power plants that will help with the envisaged lack of capacity that the company experienced. By using two scenarios for the future of growth, this study shows that the electricity demand will drop substantially due to the price policies agreed – until now – by Eskom and the National Energy Regulator South Africa (NERSA) that will affect the demand for some years. 相似文献

The evolution of price elasticity of electricity demand in South Africa: A Kalman filter application 总被引:1,自引:0,他引:1
In South Africa, the electricity mismatch of supply and demand has been of major concern. Additional to past problems, the 2008 electricity crisis made the solution crucial after its damaging consequences to the economy. The disagreement on the need and consequences of the continuous electricity price hikes worsens the situation. 相似文献

The South African Government intends to build one million houses and to electrify 2. 5 million homes in the next 5 years. Only once in a nation's lifetime does such an opportunity occur for solar and low-energy architecture to benefit all. Solar power, solar hot water and thermal design of housing present substantial savings to home owners and the nation. Legislation is presently emerging. 相似文献

This review paper presents an appraisal of renewable energy RE options in Egypt. An appraisal review of different REs is presented. The study shows that electric energy produced from REs in Egypt are very poor compared with other energy sources. The utilization of the renewable energies can also be a good opportunity to fight the desertification and dryness in Egypt which is about 60% of Egypt territory. The rapid growth of energy production and consumption is strongly affecting and being affected by the Egyptian economy in many aspects. It is evident that energy will continue to play an important role in the development of Egypt's economy in coming years. The total installed electricity generating capacity had reached around 22025 MW with a generating capacity reached 22605 MW at the end of 2007. Hydropower and coal has no significant potential increase. During the period 1981/82-2004/05 electricity generation has increased by 500% from nearly 22 TWh for the year 1981/1982 to 108.4 TWh in the year 2004/2005 at an average annual growth rate of 6.9%. Consequently, oil and gas consumed by the electricity sector has jumped during the same period from around 3.7 MTOE to nearly 21 MTOE. The planned installed capacity for the year 2011/2012 is 28813 MW and the required fuel (oil and gas) for the electricity sector is estimated to reach about 29 MTOE by the same year. The renewable energy strategy targets to supply 3% of the electricity production from renewable resources by the year 2010. Electrical Coverage Electrical energy has been provided for around 99.3% of Egypt's population, representing a positive sign for the welfare of the Egyptian citizen due to electricity relation to all development components in all walks of life. The article discusses perspectives of wind energy in Egypt with projections to generate ∼ 3.5 GWe by 2022, representing ∼9% of the total installed power at that time (40.2 GW). Total renewables (hydro + wind + solar) are expected to provide ∼7.4 GWe by 2022 representing ∼ 19% of the total installed power. Such a share would reduce dependence on depleting oil and gas resources, and hence improve country's sustainable development. 相似文献

Electricity demand in South Africa has grown at a very rapid rate over the past decade. As part of reform initiatives to enhance long-term sustainability of the country's electricity industry, South Africa's authorities have in recent years sought to develop an electricity pricing framework that is cost reflective and forms the cornerstone of demand management schemes meant to foster changes in consumption behaviour and enhance efficiency in resource use. The effects of any pricing policy on aggregate electricity consumption will depend on a useful understanding of the factors that influence electricity demand, and the magnitude to which electricity demand responds to changes in such factors. In this context, this paper applies the bounds testing approach to cointegration within an autoregressive distributed lag framework to examine the aggregate demand for electricity in South Africa during the period 1960–2007. The results indicate that in the long run, income is the main determinant of electricity demand. With electricity prices having an insignificant effect on aggregate electricity demand, future pricing policies will need to ensure that electricity prices are cost reflective and enhance efficiency of electricity supply and use. 相似文献
