Abstract

Purpose

Some of the major concerns since the implementation of smart meters (prepaid meters) in some parts of Ghana is how electricity consumers have benefited from data obtained from these meters by providing important statistics on electricity-saving advice; this is one of the key demand-side management methods for achieving load reduction in residential homes. Appliance shifting techniques have proved to be an effective demand response strategy in load reduction. The purpose of this paper is therefore to help consumers of electricity understand when and how they can shift some appliances from peak to off-peak and vice versa.

Design/methodology/approach

The research uses an analysis technique of Richardson et al. (2010). In their survey on time-of-use surveys to determine the usage of electricity in households as far as appliance shifting was concerned, this study allowed for the assessment of how the occupants’ daily activities in households affect residential electricity consumption. Fell et al. (2014) modeled an aggregate of electricity demand using different appliances (n) in the household. The data for the peak time used in this study were identified from 05:00 to 08:00 and 17:00 to 21:00 for testing the load shifting algorithms, and the off-peak times were pecked from 10:00 to 16:00 and 23:00. This study technique used load management considering real-time scheduling for peak levels in the selected homes. The household devices are modeled in terms of controlled parameters. Using this study’s time-triggered loads on refrigerators and air conditioning systems, the findings suggested that peak loads can be reduced to 45% as a means of maintaining the simultaneous quality of service. To minimize peak loads to around 35% or more, Chaiwongsa and Wongwises (2020) have indicated that room air conditioning and refrigerator loads are simpler to move compared to other household appliances such as cooking appliances. Yet in conclusion, this study made a strong case that a decrease in household peak demand for electricity is primarily contingent on improvements in human behavior.

Findings

This study has shown that appliance load shifting is a very good way of reducing electrical consumption in residential homes. The comparative performance shows a moderate reduction of 1% in load as was found in the work done by Laicaine (2014). The results, however, indicate that load shifting to a large extent can be achieved by consumer behavioral change. The main response to this study is to advise policymakers in Ghana to develop the appropriate demand response and consumer education towards the general reduction in electrical load in domestic households. The difficulty, however, is how to get the attention of consumer’s on how to start using appliances with less load at peak and also shift some appliances from off-peak times. By increasing consumer knowledge and participation in demand response, it is possible to achieve more efficiency and flexibility in load reduction. The findings were benchmarked with existing comparison studies but may benefit from the potential production of structured references. However, the findings show that load shifting can only be done by modifying consumer actions.

Research limitations/implications

It should be remembered that this study showed that the use of appliances shifting in residential homes results in load reduction benefits for customers, expressed as savings in electricity prices. The next step will be to build on this cost/benefit study to explain and measure how these reductions transform into net consumer gains for all Ghanaian households.

Practical/implications

Load shifting will include load controllers in the future, which would automatically handle electricity consumption from various appliances in the home. Based on the device and user needs, the controllers can prioritize loads and appliance usage. The algorithms that underpin automatic load controllers will include knowledge about the behaviors of groups of end users. The results on the time dependency of activities may theoretically inform the algorithms of automatic demand controllers.

Originality/value

This paper addresses an important need for the country in the midst of finding solutions to an unending energy crisis. This paper presents demand response to the Ghanaian electricity consumer as a means to help in the reduction of load in residential homes. This is a novel research as no one has at yet carried out any research in this direction in Ghana. This paper has some new information to offer in the field of demand in household electricity consumption.

Abstract

Purpose

The purpose of this study is to examine the effect of perceived value of recommended product on consumer’s e-loyalty, based on the proposition of expectation confirmation theory. Vendors’ reputation is tested as the mediator in the perceived value of recommended product and e-loyalty relationship, whereas shopping enjoyment is predicted as the moderator that conditions the perceived value of recommended product and e-loyalty relationship through vendors reputation.

Design/methodology/approach

Data were collected via an online survey platform and through a QR code. Partial least squares analysis, confirmatory factor analysis and structural equation modeling were used to verify the research proposed model.

Findings

The findings revealed that the perceived value of recommended product had a significant positive effect on E-loyalty; in addition, the perceived value of the recommended product and e-loyalty link was partly explained by e-shopper’s confidence in vendor reputation. Therefore, the study established that the direct and indirect relationship between the perceived value of the recommended product and e-loyalty was sensitive and profound to shopping enjoyment.

Originality/value

This study has established that the perceived value of a recommended product can result in consumer loyalty. This has successively provided the e-shop manager and other stakeholders with novel perspectives about why it is necessary to understand consumers’ pre- and postacquisition behavior before recommending certain products to the consumer.

Abstract

Purpose

The purpose of this paper is to investigate the impact of temperature on residential electricity demand in the city of Greater Accra, Ghana. It is believed that the increasing trend of temperatures may significantly affect people’s lives and demand for electricity from the national grid. Given the recurrent electricity crisis in Ghana, this study will investigate both the current and future residential energy demands in the light of temperature fluctuations. This will inform future power generation using renewable energy resources mix to find a sustainable solution to the recurrent energy demand challenges in Ghana. This study will help the Government of Ghana to better understand the temperature dependence of residential energy demand, which in turn will help in developing behavioral modification programs aimed at reducing energy consumption. Monthly data for the temperature and residential electricity consumption for Greater Accra Region from January 2007 to December 2018 obtained from the Ghana Meteorological Service (GMS) and Ghana Grid Company (Gridco), respectively, are used for the analysis.

Design/methodology/approach

This study used monthly time series data from 2007 to 2018. Data on monthly electricity demand and temperature are obtained from the Ghana Grid Company and GMS. The theoretical framework for residential electricity consumption, the log-linear demand equation and time series regression approaches was used for this study. To demonstrate certain desirable properties and to produce good estimators in this study, an analysis technique of ordinary least squares measurement was also applied.

Findings

This study showed an impact on residential electricity requirements in the selected regions of Greater Accra owing to temperature change. The analysis suggests a substantial positive response to an increase in temperature demand for residential electricity and thus indicates a growth of the region’s demand for electricity in the future because of temperature changes. As this analysis projects, the growth in the electricity demand seems too small for concern, perhaps because of the incoherence of the mechanisms used to regulate the temperature by the residents. However, two points should be considered when drawing any conclusions even in the case of Greater Accra alone. First, the growth in the demand for electricity shown in the present study is the growth of demand due only to increasing temperatures that do not consider changes in all the other factors driving the growth of demand. The electricity demand will in the future increase beyond what is induced by temperature, due to increasing demand, population and mechanization and other socioeconomic factors. Second, power consumption understated genuine electricity demand, owing to the massive shedding of loads (Dumsor) which occurred in Ghana from 2012 to 2015 in the analysis period that also applies in the Greater Accra region. Given both of these factors, the growth in demand for electricity is set to increase in response to climate change, which draws on the authorities to prepare more critically on capacity building which loads balancing. The results also revealed that monthly total residential electricity consumption, particularly the monthly peak electricity consumption in the city of Accra is highly sensitive to temperature. Therefore, the rise in temperature under different climate change scenarios would have a high impact on residential electricity consumption. This study reveals that the monthly total residential electricity demand in Greater Accra will increase by up to 3.1%.

Research limitations/implications

The research data was largely restricted to only one region in Ghana because of the inconsistencies in the data from the other regions. The only climate variable use was temperature because it was proven in the literature that it was the most dominant variable that affects electricity demand, so it was not out of place to use only this variable. The research, however, can be extended to capture the entire regions of the country if sponsorship and accurate data can be obtained.

Practical implications

The government as the policy and law-making authority has to play the most influential role to ensure adaptation at all levels toward the impact of climate change for residential consumers. It is the main responsibility of the government to arrange enough supports to help residential consumers adapt to climate change and try to make consumers self-sufficient by modification of certain behaviors rather than supply dependent. Government bodies need to carefully define their climate adaptation supports and incentive programs to influence residential-level consumption practices and demand management. Here, energy policies and investments need to be more strategic. The most critical problem is to identify the appropriate adaptation policies that favor the most vulnerable sectors such as the residential sector.

Social implications

To evaluate both mitigation and adaptation policies, it is important to estimate the effect of climate change on energy usage around the world. Existing empirical figures, however, are concentrated in Western nations, especially the USA. To predict how electricity usage will shift in the city of Greater Accra, Ghana, the authors used regular household electricity consumption data.

Originality/value

The motivation for this paper and in particular the empirical analysis for Ghana is originality for the literature. This paper demonstrates an adequate understanding of the relevant literature in modern times.

Abstract

Purpose

Net zero energy buildings (NZEBs) play a crucial role in mitigating the environmental impact of the construction industry. However, this concept in Ghana is still in the infancy stage, and the level of embracement in the construction industry is uncertain which further poses challenges to its adoption. This can be attributed to the lack of awareness of NZEB among construction professionals. Hence, understanding the awareness among construction professionals is essential for promoting sustainable building practices and reducing the carbon footprint of buildings. Therefore, this study investigates the level of awareness of NZEBs among construction professionals in the Ghanaian construction industry (GCI).

Design/methodology/approach

The study adopted a quantitative research method where questionnaire survey was used to obtain data from sixty-six (66) construction professionals in the GCI through snowball sampling technique. The collected data were analysed using frequencies, mean scores, one-sample t-test and cross-tabulation.

Findings

The study revealed that thirty (30) construction professionals out of the sixty-six (66) had a moderate level of awareness of NZEBs, and 14 professionals had a low level of awareness. Thirteen had a high level of awareness. Three of the profesionals were extremely unaware, while six had a very high level of awareness. The study’s findings highlight the need to create awareness of NZEBs and their practices among construction professionals and employees in Ghana.

Originality/value

NZEB is an under-explored area in the Ghanaian context and therefore, this study uniquely highlights the nascent awareness of NZEBs among Ghanaian construction professionals, unlike previous studies in more developed contexts. It underscores the critical need for targeted awareness programs essential for reducing the carbon footprint and advancing the adoption of NZEBs in the GCI.

Abstract

Purpose

This study aims to examine the impact of financial inclusion and bank stability on agricultural productivity in Sub-Saharan Africa (SSA).

Design/methodology/approach

The study used 38 countries in the SSA with data spanning between 2004 and 2021. The data were analyzed using the two-step system generalized method of moments (GMM) and the panel-corrected standard error (PCSE) model.

Findings

The study found a positive effect of financial inclusion and bank stability on agricultural productivity. The study also discovered that while the access component of financial inclusion has a negative influence on agricultural productivity, the usage dimension has a positive impact.

Research limitations/implications

The study suggests to policymakers that an inclusive and stable financial system improves agricultural productivity. The findings recommend that policymakers should empower farmers to leverage financial inclusion.

Originality/value

This study provides insightful discussion on the impact of financial inclusion and its various dimensions and bank stability on agricultural productivity in SSA.

Abstract

Purpose

Green building (GB) is globally acclaimed as the most formidable solution to the adverse effects that buildings and construction activities have on the climate and environment. Nonetheless, current evidence suggests that the adoption of GB in developing countries of Sub-Saharan Africa (SSA) is at a snail’s pace and characterized by the absence of GB codes and frameworks. This paper aims to determine the current level of adoption and implementation of GB concepts and technologies in the Ghanaian construction industry (GCI).

Design/methodology/approach

An exploratory method of investigation involving a quantitative approach was used to achieve the objectives of this study. A literature review was conducted, and a questionnaire survey was conducted among 292 stakeholders in the GCI. The survey data was analyzed using descriptive and inferential statistics as well as other quantitative analysis techniques.

Findings

The analysis revealed that the five most applied green building technologies (GBTs) are technologies for optimizing site planning, building orientation and configuration, use of natural ventilation, integrative use of natural lighting with electric lighting systems, application of energy-efficient lighting systems and use of permeable paving: low-traffic areas. Notably, the majority of the GBTs belong to the energy-efficiency technologies category.

Research limitations/implications

The findings indicate that GBTs are gaining momentum in Ghana and that there is a need for ongoing research to develop new and more environmentally friendly building technologies to aid in the preservation of our society and natural resources to achieve United Nations Sustainable Development Goals (UN SDGs) 12 and 13.

Originality/value

In effect, this study will enhance the awareness of GB development and contribute to the GB body of knowledge, particularly in the context of developing countries. It would also be useful to the GCI’s contribution to achieving the UN SDGs.

Abstract

Purpose

Energy and environment has gained traction within the field of entrepreneurship literature, but a comprehensive empirical study that examines the relationship between the cost of energy and small- and medium-sized enterprise (SME) innovation is an omission. Therefore, this novel study aims to examine the relationship between the cost of energy and SMEs innovation in Sub-Saharan Africa (SSA) by first examining the differential impact of the various generation sources on the price of electric energy. This research has enabled us to investigate and understand the transmission mechanism of increasing/decreasing electricity price on innovation decisions and activities of SMEs in SSA.

Design/methodology/approach

Using quantitative approach, with the data from the World Bank Enterprise and Innovation Follow-up Surveys, the study utilises a Tobit model to test whether the generation mix (renewable and non-renewable generation sources) increases or decreases electricity prices and examine the impact of the cost of electric energy on SMEs innovation in SSA.

Findings

The findings of this study shows that the cost of electricity affects negatively on SMEs innovation decision and activities of SMEs in SSA. The impact of renewables on the price of electricity has a larger magnitude relative to that of non-renewables. This finding has implications for policy makers promoting renewable energy without a policy design to tackle the unintended price effect of promoting renewable energy.

Originality/value

This is the first study to introduce cost of energy into an innovation model and to empirically examine the role of cost of energy for innovation activities of SMEs in SSA. Further, it examines the sources of generation on electricity price in SSA. The study contributes towards the empirical literature, and the findings also have implication for policy makers regarding the unintended consequences of promoting the transition to low-carbon electricity generation sources on SMEs via the cost of doing business implication.

Abstract

Purpose

The efficiency of each of an organization’s individual workers determines its effectiveness. The study aims to explore the relationship between human resource management (HRM) practices and organizational effectiveness with employee performance as a mediating variable.

Design/methodology/approach

Data were collected from 800 police officers in the Greater Accra and Tema regions. The data were supported by the hypothesized relationship. Construct reliability and validity was established through confirmatory factor analysis. The proposed model and hypotheses were evaluated using structural equation modeling.

Findings

The results show that career planning and employee performance were significantly related. Self-managed teams and employee performance were shown to be nonsignificantly related. Similarly, performance management and employee performance were shown to be nonsignificantly related. Employee performance significantly influenced organizational effectiveness. The results further indicate that employee performance mediates the relationship between HRM practices and organizational effectiveness.

Research limitations/implications

The generalizability of the findings will be constrained due to the research’s police service focus and cross-sectional data.

Practical implications

The study’s findings will serve as valuable pointers for the police administration in the adoption, design and implementation of well-articulated and proactive HRM practices to improve the abilities, skills, knowledge and motivation of officer’s to inordinately enhance the effectiveness of the service.

Originality/value

By evidencing empirically that employee performance mediates the relationship between HRM practice and organizational effectiveness, the study extends the literature.

Abstract

Purpose

The purposes of this study are: to investigate how the dimensions of resource competitive strategies impact on small and medium enterprises’ (SMEs) intention to invest in Ghana’s downstream petroleum sector and to develop a model to explain the moderating role of local content policy on the relationship between competitive strategies and investment intention of SMEs. Focusing on the Ghanaian SMEs, quantitative research approach and survey questionnaire have been used. The research hypotheses have been tested using variance-based structural equation modeling technique.

Design/methodology/approach

Since the Ghanaian Parliament passed the Local Content and Local Participation Policy (LI.2204) into law in 2013, successive governments have strived to optimize oil and gas benefits and encouraged local participation, yet the actual impacts are mixed, ambiguous and inconsequential. This paper further argues that the extent to which the local content policy role moderates the relationship between firms’ internal resources (proxied as competitive strategies) and investment intention in the energy sector remains largely unexplored.

Findings

The results have shown that competitive strategies such as entrepreneurial competency, finance resources and technological usage have positive and significant effects on SME's investment intention. Again, local content policies exert significant moderating effect on SMEs’ investment intention.

Practical implications

The policy implication of these results includes the need to strengthen regulatory capacity of the Petroleum Commission to enforce local content implementation in Ghana to enhance indigenous participation in the sector.

Originality/value

Theoretically, using the resource-based view theory, this study has offered a robust predictability of SMEs investment’s determinants in an emerging economy.
