Current sources of financing power infrastructure in developing countries : principal component analysis approach

Abstract: Infrastructure plays the dominant role in structuring and positioning every nation’s economy and social development. Infrastructure financing is the blue print in achieving infrastructure development in developing and developed countries. This research project determines the current sources of financing infrastructure in developing countries. The study adopted a quantitative research approach with data gathered from the respondents within power infrastructure development in the region. The findings revealed current sources of financing power infrastructure in developing countries to be commercial bank loans, public finance, private finance, power utility fees, public-private partnership, foreign direct investment. These were seen as current sources of financing power infrastructure in developing countries. Having established that no society can develop without adequate investment in the power infrastructure sector, there is a call for adequate investment in the power infrastructure to foster and re-integrate developing countries in the path of economic development and global relevance. If the central government can direct adequate finance and harness the current sources available to develop power infrastructure in their society, it will ultimately lead to enormous economic growth and social development in the region. This research project will contribute to the development of public infrastructure in developing countries, which will directly influence the development of power infrastructure in the region for the purpose of economic relevance and improvement of lives in the society

Solar PV rural electrification and energy poverty assessment in Ghana: A principal component analysis

The relationship between solar photovoltaic (PV) rural electrification and energy poverty was assessed using social, economic and environmental indicator-based questionnaires in 96 solar-electrified and 113 non-electrified households in rural Ghana. The purpose was to assess energy-poverty status of households with and without solar PV systems, and to determine the factors that explain energy-poverty in off-grid rural households. Principal component analysis (PCA) was used to construct energy-poverty index scores (EPIS). On the basis of the results of the EPIS, about 80% of the non-electrified households were assessed as relatively energy poor compared with only 10% of the solar-electrified households. Three significant indicators increased linearly with increasing EPIS and therefore explained the variation in EPIS. They are monthly savings on lighting (r2=0.214), number of children who can sit around lighting (r2=0.388) and amount paid to obtain lighting/electricity system (r2=0.261). On the contrary, EPIS decreased linearly with increasing monthly costs of kerosene, candles and dry-cell batteries. This indicates that increasing expenditure on kerosene, candles and dry-cell batteries is likely to affect household savings and investment in quality energy delivery systems that can increase EPIS. To improve EPIS, households should invest a bit more in reliable and quality energy delivery systems, which can help to improve their quality of life. The use of EPIS successfully demonstrated the difference in energy-poverty status between households with and without solar PV. This lays down a basis of understanding the relationship between solar PV rural electrification and energy poverty improvement in off-grid communities

Readability Analyses of Integrated Science Textbooks for Junior High Schools in Ghana

This study investigated the readability levels of some integrated science textbooks approved for use in junior high schools (JHS) in Ghana. To assess the readability levels of the approved integrated science textbooks in order to ascertain their difficulty or ease, the researchers used the Flesch Readability Ease and Flesch-Kincaid Readability Formulas Cloze Test to determine the comprehension levels for a sample of students. A sample of 135 pupils, drawn from rural, peri-urban and urban JHS years 1 through 3 in the Ashanti region participated in the study. The outcome of the assessments revealed that the selected textbooks had a problematic level of comprehension for many of their intended readership except those who had additional resources for assistance. The study also revealed that these approved books employed long sentences and multi-syllabic words to deliver lessons and instructions, making them difficult for JHS pupils to understand

Pathways to achieve universal household access to modern energy by 2030

A lack of access to modern energy impacts health and welfare and impedes development for billions of people. Growing concern about these impacts has mobilized the international community to set new targets for universal modern energy access. However, analyses exploring pathways to achieve these targets and quantifying the potential costs and benefits are limited. Here, we use two modelling frameworks to analyse investments and consequences of achieving total rural electrification and universal access to clean-combusting cooking fuels and stoves by 2030. Our analysis indicates that these targets can be achieved with additional investment of US$(2005)65-86 billion per year until 2030 combined with dedicated policies. Only a combination of policies that lowers costs for modern cooking fuels and stoves, along with more rapid electrification, can enable the realization of these goals. Our results demonstrate the critical importance of accounting for varying demands and affordability across heterogeneous household groups in both analysis and policy setting. While the investments required are significant, improved access to modern cooking fuels alone can avert between 0.6 and 1.8 million premature deaths annually in 2030 and enhance wellbeing substantially

An energy vision for a planet under pressure

Worldwide, global energy systems face an array of challenges, from access for the poor to reliability and security. Meanwhile, the provision of energy creates local human and ecological health impacts as well as dangerous global climate change. Addressing these issues simultaneously will require a fundamental transformation of the energy system. Recent assessments show that such a transformation is achievable in technological and economic terms, but it will present formidable supply- and demand-side challenges as well as problems of governance, transparency and reliability across scales. This policy brief presents a long-term vision for the energy system and describes the elements required for the transition towards this vision. To succeed, this transformation must integrate several key components, including a focus on high levels of energy efficiency and the scale up of investments in technology deployment as well as research, development and demonstration (RD&D)

Energy Access Scenarios to 2030 for the Power Sector in Sub-Saharan Africa

In order to reach a goal of universal access to modern energy services in Africa by 2030, consideration of various electricity sector pathways is required to help inform policy-makers and investors, and help guide power system design. To that end, and building on existing tools and analysis, we present several ‘high-level’, transparent, and economy-wide scenarios for the sub-Saharan African power sector to 2030. We construct these simple scenarios against the backdrop of historical trends and various interpretations of universal access. They are designed to provide the international community with an indication of the overall scale of the effort required. We find that most existing projections, using typical long-term forecasting methods for power planning, show roughly a threefold increase in installed generation capacity occurring by 2030, but more than a tenfold increase would likely be required to provide for full access – even at relatively modest levels of electricity consumption. This equates to approximately a 13% average annual growth rate, compared to a historical one (in the last two decades) of 1.7%.Energy Access, Power System Planning, Sub-Saharan Africa

Powering production. The case of the sisal fibre production in the Tanga region, Tanzania

Energy plays a crucial role in economic development. The article presents a framework for the analysis of alternative energy technology mixes in agricultural production and applies it in the context of sisal production in the Tanga region, Tanzania. Through scenario analysis, the paper presents both case-specific and generalizable insights. Case-specific insights show the key role that modern uses of energy and modern agricultural technologies could play in increasing productivity and revenues, in minimizing environmental degradation, and in promoting local development. Generalizable insights demonstrate the value of using sector-specific micro-structural frameworks and scenario analysis for assessing different technologies mixes in the energy and agriculture planning process
