Full textAbstract:
Zambia has in the recent past witnessed an increase in economic activities which has led to an increased energy demand. This increased demand for energy has overshot the hydroelectric power generating capacity. Consequently, the national power utility company, the Zambia Electricity Supply Corporation (ZESCO) instituted nationwide load shedding schedules that last up to 12 hours daily. This development has potentially far reaching social and economic effects on the lives and operations of poor urban residents and small scale business enterprises (SMEs) that routinely depend on stable access to electricity. With a focus on two low income residential areas, namely Ng’ombe and Kalingalinga residential areas, this study explored how residents and SMEs of the capital city, Lusaka have been affected by the recent spate of load shedding in the city. A total of 200 households and 14 SMEs from Ng’ombe and Kalingalinga were interviewed. Results show that load shedding, which occurs daily in the two study sites has caused massive disruptions to the daily lives and operations of the households and small businesses respectively. Over time, the load shedding phenomena has gotten worse and become a major political issue, reflecting the hardships for households and businesses in Zambia. On this basis, this study recommends that the government provides subsidies on alternative energy appliances such as portable diesel solar generators for small business enterprises and more favourable electric tariff rates for business that shift their manufacturing activities to night time so as to reduce demand for electricity during peak periods.

Abstract Water supply systems that operate intermittently rather than continuously are highly complex. This arises from the interaction of large numbers of internal and external factors that produce major consequences for system operation and management. Handling these problems requires understanding, and to some extent eliminating, their causes. In this paper, Lusaka Water and Sewerage Company, Zambia, is used as a case study that shows how poor governance, demographic and economic dynamics, hydrologic regime change, poor system management and operation, unplanned system extensions, limited skilled manpower, poor electricity supply and lack of customer awareness all contribute to sustaining intermittent water supply. Interdisciplinary approaches are recommended to explore interplays between governance, climate change and technical factors when developing solutions to intermittent supplies.

Full textAbstract:
The mining industry in Zambia is energy-intensive, with hydro energy providing the required energy. But other sources of energy may need to be added, because hydro energy is subject to good rain patterns, threatened by the spectre of climate change, as already indicated by the current prolonged hours of load shedding by state-owned , Zambia Electricity Supply Company. This research looks at state-of-art mining technologies and collaborative business processes that leverage on the expected ramp in copper and cobalt (Cu-Co) global demand post-Covid-19, to help design resilient business systems by manufacturing, source goods and services within the Southern African Development Community (SADC) region to lower Cu-Co production costs, and maximise profits through shared resources and bilateral trade agreements. With evidence, projection and predictions by global leaders in the Cu-Co industry, this study evaluates the preparedness and resilience of the Zambian mining industry for sustainable energy supply, environmental sustainability, and suggests some possible business collaborations within the SADC region to share the following resources: metal refineries, transportation of goods and services, expertise and energy supplies within SADC, to enhance business sustainability. The study shows that the resilience of Cu-Co business in resource-rich nations like Zambia is complex and is heavily influenced by investment decisions, stakeholder interests, copper ore grades and extractive process types, reliable power supply, and socio-economic and political issues. The significance of this study is that it proposes some business collaborations within SADC that can increase energy reliability and supply, Cu-Co production, increase business resilience, improve global competitiveness and sustainability by exploring energy efficiency and generation-mix strategy.

Full textAbstract:
This paper aims at understanding how Zambia’s electricity system would be affected by droughts (due to a dry year) and how the system’s adaptive capacity could be improved. Hydropower currently supplies 99% of the total electricity in Zambia, and concerns have been raised because many climate change studies project increased occurrences of dry years in the Southern Africa region. Different economic and climatic scenarios were explored to understand their impact on the development of Zambia’s power generation system, and what policies and strategies could be adopted to mitigate these impacts on security of supply and average generation costs, which directly affect the electricity price. The results show that a dry year has significant impact on the average generating cost since hydropower continues to dominate the system. Diversifying the system does not improve the adaptive capacity of the system but only increases the average cost of generating electricity in an average year. The most cost effective way of increasing the system’s adaptive capacity is by importing electricity and gradually increasing share of renewable and coal technologies in the system. Further research on how electricity trade in Southern Africa could be enhanced, should be done.

Full textAbstract:
Bioenergy can play an important role in achieving the agreed United Nations Sustainable Development Goals (SDGs) and implementing the Paris Agreement on Climate Change, thereby advancing climate goals, food security, better land use, and sustainable energy for all. In this study, we assess the surplus agricultural residues availability for bioelectricity in six least developed countries (LDCs) in Asia and Africa, namely Bangladesh, Lao-PDR, and Nepal in Asia; and Ethiopia, Malawi, and Zambia in Africa, respectively. The surplus agricultural residues have been estimated using residue-to-product ratio (RPR), agricultural residues lost in the collection, transportation and storage, and their alternative applications. We use a linear regression model to project the economic potential of bioelectricity. The contribution of bioelectricity for meeting the LDCs’ electricity requirements is estimated in a time frame between 2017 and 2030. Our results reveal that the surplus biomass feedstock available from the agriculture sector could provide the total current electricity demand in Malawi alone, followed by Nepal (45%), Bangladesh (29%), Lao People’s Democratic Republic (Lao-PDR) (29%), Ethiopia (27%), and Zambia (13%). This study also explores the complementarity and synergies of bioelectricity, SDG7, and their interlinkages with other SDGs. Findings from the study show that providing access to sustainable energy in the LDCs to meet the SDG7 by 2030 might be a challenge due to limited access to technology, infrastructure, and finance. Site-specific investigations on how much agricultural residues could be extracted in an environmentally benign manner for bioelectricity and increased investment in the bioenergy sector are key potential solutions in a myriad of options required to harness the full energy potential in the LDCs.

Full textAbstract:
From as early as the 1880s until today, electrical power has served as a useful medium for ushering an urban industrial era throughout the world. This article examines the process of electrification in a colonial setting—Calcutta, the capital of British India till 1911. Access to electricity depended upon economics and technological advances, as well as a combination of local community and regional characteristics such as location, landscape, demographics, politics and culture. Western techno-scientific discourse occupied an extremely important place in the colonization of India. It is known that Western technology and ideas manipulated various technological projects in the colony, including electrification. Was there something unique about Calcutta and its plan that led to the electrification of a colonial metropolis almost simultaneously with other Western industrial nations? By the middle of the twentieth century, electricity, with its elaborate infrastructure of wires, generation stations and poles, emerged as the industrial era’s most prominent symbol of progress in Calcutta. The Calcutta Electric Supply Corporation Ltd (CESC), with its head office in London, played the most vital role, debating and resolving various technical questions, such as load factor, fuel sources, operating generation stations and electricity supply to industry, traction and population centres. This article, based on extensive archival research, shows how, despite colonial derivatives, the resulting electrical systems were locally initiated and customized to the needs and characteristics of the region.

Full textAbstract:
Wood fuel, charcoal, and firewood comprise over 70 percent of the national energy consumption in Zambia, as only about 25 percent of the population has access to electricity. Replacing charcoal braziers with cookstoves using sawdust pellets can support sustainable energy provision in urban Zambia while reducing deforestation on the countryside. However, acceptability of pellet cookstoves remains low, while the demand for wood fuel is increasing. The study investigated the acceptability of pellet cookstoves, in view of governmental policies, in the Matero-George compound, Lusaka. Qualitative approaches were applied, and respondents were households, and officers at the Departments of Energy and Forestry, and at Lusaka City Council. Factors shaping the stoves’ acceptability included their convenience, possibility of reusing pellets, their long-term cost advantages, and the perceived health benefits of pellets. The barriers included limited supply of pellets, combustible pellet cookstoves, stove size, maintenance costs, cooking traditions, and government policies for dissemination, sensitisation, and communication about pellet stoves. This study demonstrated that implementation of pellet cookstoves at the local level depends on a multitude of contextual factors, and confirms the need for relevant policy instruments if such energy consumption is to be accepted.

Full textAbstract:
This paper examines the energy consumption, supply and resources of some of the countries in the Southern African Development Community (SADC) in 2005, the base year for this analysis. The region is rich in energy resources and currently enjoys relatively stable and affordable electricity. Except in the case of Botswana, Mauritius, Namibia and South Africa, final energy demand is dominated by the residential sector in the form of biomass. Energy consumption or final energy demand in Angola, Botswana, Mozambique, South Africa, Tanzania, Zambia and Zimbabwe is projected to 2030 using a Long Range Energy Alternatives Plan-ning (LEAP) model in a ‘business as usual’ scenario, the other countries being left out because of poor quality data. The projections are carried out by relating historic sectoral GDP and population growth in each country to energy demand and then using the historical link and the projections of these drivers to project energy demand. The analysis under this ‘business as usual’ scenario seems to indicate that we can expect to see a large increase in consumption in these countries, especially in the form of biomass and electricity. In both cases, supply is a concern. Having established what the present resources are; what some of the supply elements are currently in place; what the base-year demand is; and some basic relationships between demand and socio-economic drivers, this paper sets the stage for further studies that include the future energy supply; regional trade; and scenario analysis using indicators of sustainable development for the region. However, further analysis of the regional energy system, is only valuable if it is supported by good data. A reliable energy balance is needed for the countries not modelled here, and in the case of the modelled countries, better data is also needed, especially in the use biomass.

Applied research has value to the extent that it assists management to make better decisions. It is only through a scientific thinking process that we come to understand, and take into consideration, the complex set of factors that operates in any given situation. Having analysed the results from the data analysis the manager exercises good judgment by using both the research findings and drawing on the personal and invaluable resources of past experience. In sum, research indicates the direction of problem solving; experience and common sense, in conjunction with scientific research results. One without the other is not completely effective. This Dissertation sets out to carry out a strategy evaluation of the ZESCO Business Plan using a set strategy evaluation criteria of; suitability, acceptability and feasibility. In conducting this evaluation, it is recognised that; although it is impossible to demonstrate conclusively that a particular business strategy is optimal or even guarantee that it will work, one can nevertheless, test it for critical flaws using a set criteria. The results from the evaluation revealed that; in terms of suitability some of the strategies scored lowly due to the low disposable incomes of ZESCO's customers; in terms of acceptability of ZESCO's strategies to its principle stakeholders, there is a need for it to improve the input from these stakeholders when formulating its strategies and lastly the feasibility analysis revealed that ZESCO will struggle to implement its strategies. Lastly the importance of carrying out Business Research is well summed up by Sekaran (2000: 4) "the difference between the manager who uses common sense alone to analyze and make a decision in a given situation, and the investigator who uses a scientific method, is that the latter does a systematic inquiry into the matter and proceeds to describe, explain, or predict phenomena based on data carefully collected for the purpose.Thesis (MBA)-University of KwaZulu-Natal, 2006.

This chapter considers reforms in a few selected areas. On macroeconomy, the key recommendation is an upward revision of the inflation target. It suggests that when public sector enterprises incur losses and serve no public purpose, the government should sell them if possible and close them if there are no potential buyers. It recommends consolidation of subsidies to farmers and conversion to a single cash transfer via the universal Aadhaar biometric identity. It also suggests scaling down the Food Corporation of India, splitting electricity distribution companies into network and supply businesses and opening entry into the latter, and amending the Right to Education Act to improve learning outcomes.

Full textAbstract:
The current renewable energy transformation taking place around the world has led to drastic advances in technology that relates to the issue of climate change. Although many solutions have been found and/or created, there has yet to be one that can, on its own, solve the problem of finding an environmentally friendly energy source. This leads to the challenge of creating an integrated system which relies on several components with different types of energy. It has been the goal of this study to further enhance an off-grid renewable energy power system to supply economical, secure, and continuous electrical power, in an environmentally conscious way, for various types of loads. The previous power system consisted of a mobile unit with inverters, batteries, hydrogen generator, hydrogen storage, propane storage and an internal combustion engine generator that was connected to photovoltaics and wind turbines while being controlled and monitored by a single computer unit. The only pollutants emitted from this power system were the result of the use of propane as a backup fuel, when renewable energy was insufficient. Even though propane is a fossil fuel, its use in this study allowed the system to be simpler and more cost effective. With the assistance of Southwest Gas Corporation, a more efficient and reliable internal combustion engine was acquired. The three cylinder engine, with a 10,000 hour maintenance interval, was converted from natural gas to combust either hydrogen or propane. The engine provides mechanical power to a belt driven alternator supplying electricity to the load and other components of the system. Initial testing of the engine achieved engine dynamometer efficiency of over 40% using propane at wide open throttle and 45% using hydrogen at wide open throttle. The output under these conditions was roughly 20 HP using propane and 10 HP using hydrogen. The current system is not mobile but has the potential to be mobile by using an existing KOH electrolyzer for hydrogen generation with a larger output and hydrogen storage capacity.

Full textAbstract:
Solar energy is an influential sort of renewable energy which is also richly available in North Cyprus. Contrariwise, there are no natural oil resources in Cyprus; over 90% of the country's main energy is imported to the island which needs high financial government credit [1]. Indeed, high CO2 emissions and their side effects on the global environment as well as destruction role on the ozone layer are among major problems of using non-renewable energy. Considering the geographic location of North Cyprus, it has over 300 sunny days out of 365 days of a year; therefore, there is a considerable potential to integrate solar tracking systems into various parts of industrials or residential portions in the country. In a time when using more renewable sources of energy is important to decline obvious environmental problems, it seems to be beneficial to use photovoltaic systems such as "Building Integrated Photovoltaic". As housing consumes over 40 percent of the produced energy, local sustainable properties deal with enhancing the quality of dwellers life. Based on what has been discussed, the objective of this study is to achieve a high degree of efficient local energy through BIPV so to supply a proportion of buildings' heating and electricity power consumptions. The main concern is considering cultural patterns and local climate aspects in the design process so to reach to a suitable energy solution in each individual case. Accordingly, some criteria which directly affect the produced power ability of photovoltaic systems would be discussed, in particular, determining the direction, the slope of photovoltaic panels, shading, its integration with active solar systems, and buildings' form and facades. Additionally, as the case study, Coloured Building would be presented to show that how those mentioned solutions can integrate to the building in order to refine its energy consumption. Consequently, architects and designers, looking for buildings' self-efficiency and sustainability, should know how to incorporate photovoltaic systems to the building and to consider which criteria in this case. Indeed, the corporation between architects and other engineers who work on a common project is the key role in developing a construction toward a sustainable environment.
