Discussions of energy in sub-Saharan Africa tend to focus on leapfrogging, theorizing how some non-Western countries might be able to avoid carbon-intensive fuels, such as coal and oil, and directly start using renewable energy infrastructure, mainly solar. While theories of leapfrogging have been attractive, there has been limited research on how exactly renewable energy resources are adopted in sub-Saharan Africa, especially at times of unreliable access. Drawing on fieldwork with energy professionals in Accra and Tema, Ghana, this article analyzes the transformations in energy infrastructure in Ghana during the period following its 2012–16 electricity crisis, known as dumsor. It argues that an increasing volume of rooftop solar panels installed by affiuent individuals and institutions in the aftermath of the crisis has led to declining participation in the electricity grid, and thereby higher electricity rates for everyone else with no choice but to remain on the grid. In response to such growing inequality, decision-makers searched for innovative business models, appealing to green loans as ways of expanding this class of solar consumers. As a result, while a select few have managed to leapfrog to renewables, others continue to endure the grid, struggling with unsteady electricity provision and increasing tariffs.

Worldwide, developing countries struggle to overcome numerous problems that constrain their socio-economic development. Sub-Saharan African countries represent a good example of developing countries with serious developmental challenges. Thus, this chapter presents a critical analysis on the socio-economic situation in Sub-Saharan Africa and the links between limited access to modern energy services and the prevailing socio-economic circumstance. It discusses the expected roles of renewable energy technologies in increasing energy access in the region and highlights important factors that influence extensive deployment of renewable energy technologies for sustainable development. Reliable statistical data on both the Human Development Index (HDI) and Energy Development Index (EDI) rankings indicate that most countries in Sub-Saharan Africa lie far below the world average and as a region, Sub-Saharan Africa scores least. There is high level of poverty and inadequate social services, which is attributed to acute shortage of modern energy services. In Sub-Saharan Africa, over 70% of the population lack reliable access to electricity and modern cooking fuels, which represents a large proportion of the „energy poor‟ in the world. Lack of access to modern energy services limits economic and agricultural opportunities, negatively affects the environment, promotes gender inequality and constrains delivery of social services such as health care delivery system and education. Thus, one of the biggest developmental challenges in Sub-Saharan Africa is to find effective and pragmatic solutions for increasing energy access. Sub-Saharan Africa is richly endowed with renewable energy resources such as biomass, wind, solar, hydropower and geothermal, which largely remain unexploited. The renewable energy resources are widely available throughout the region unlike the conventional fossil-based resources, that is, coal, oil and gas, which are concentrated within very few countries. Therefore, the renewable energy resources if properly and fully utilized can provide clean, affordable and reliable energy services that will promote socio-economic activities and support sustainable development.

The extension of modern energy services to rural sub-Saharan Africa has continuously provided a challenge to energy utilities. The continued reliance on diesel generators for rural electrification is increasingly becoming unsustainable, due to a number of factors, among which includes their high fuel dependency, and the uncertainty surrounding the price and availability of fossil fuels. While the influx of renewable energy technologies has provided a means for providing off-grid electrification services, the intermittent nature of renewable resources poses a challenge, as energy generation does not always coincide with usage. Through a combination of renewable energy technologies, energy storage, and conventional diesel generation, a hybrid mini-grid system is able to achieve synergy in operation, hence providing a reliable means of extending electricity services to rural consumers. In this paper, a hybrid mini-grid system is proposed for the supply of electricity to a remote village in Uganda. Renewable energy resources are identified, an estimation of the projected village short-term electricity demand is modelled, and using HOMER software, a hybrid mini-grid system is designed, components sized, and the system optimized for efficient and reliable operation to meet the village demand at an affordable cost. A well designed and operated hybrid mini-grid system offers a viable tool for the electrification of even the remotest of areas.

At the University of Szeged, as the greenest University of Hungary, the sustainability project is built on two pillars. One of them is based on events and communication campaigns held regularly for the University citizens to prompt environmental-conscious behaviour, whereas the other is built on technological developments and on the extensive use of renewable energy resources. Thus the development of built environment and social responsibility both support the adequacy to sustainability requirements. The spreading of the effective solutions to making more and more buildings of the University energy efficient, numerous investments using renewable energy are also responsible for the decrease of the natural energy use of the institution contrary to the fact that the number of the buildings of the University of Szeged is continually increasing. It can be stated that the University of Szeged is committed to using renewable energy which is taken into consideration of each investment planning. The following examples confirm it: using geothermal cascade system for heating and cooling of five university bulidings, solar panels on 24 builidings and a unique technology of using the heat of wastewater to cool and heat one of the main bulidings of the university, namely the Study and Information Centre.
