Over the past three decades, new off-grid electrification infrastructures – as micro-grids and other solar solutions – have moved from innovative initiatives, conducted by NGOs and private stakeholders, to a credible model promoted by international organizations for electrification of rural areas in developing countries. Multiple conditions support their spread: major technological advances in the field of renewable energies (panels, batteries), intensive Chinese industrial production allowing lower prices, institutional reforms in Africa including these solutions in major national electrification programmes, and, finally, an opening to the private sector as a supposed guarantee of the projects’ viability. However, while the development of this market calls for significant investments, a vast set of calculations and a strong “micro-capitalist” doctrine, all involved in their design, experts admit that a large proportion of projects hardly survive or even fail.

This chapter investigates these failures by exploring the ecology of such infrastructures, designed for “the poor.” It discusses “thinking infrastructures” in terms of longevity by focusing on economic failures risks. The authors argue that the ecology of the infrastructure integrates various economic conversions and exchanges chains expected to participate in the infrastructure’s functioning. By following energy access solutions for rural Africa in sub-regions of Senegal and Madagascar, from their political and technical design to their ordinary life, the authors examine the tensions and contradictions embedded within the scripts of balance supposed to guarantee their success.

This study aims to analyze the effects of variations in annual real interest rates in the assessment of the techno-economic feasibility of a hybrid renewable energy system (HRES) for an off-grid community.

Hybrid Optimization of Multiple Energy Resources (HOMER) software is used to propose an HRES for Abadam community in northern Nigeria. The HRES was designed to meet the basic needs of the community over a 25-year project lifespan. Based on the available energy resources in the community, photovoltaic (PV), wind turbine, diesel generator and battery were suggested for integration to serve the load requirements.

When the annual real interest rates were taken as 10 and 8 per cent, the total amount of total energy fraction from PV, wind turbine and the diesel generator is 28, 57 and 15 per cent, respectively. At these interest rates, wind turbines contributed more energy across all months than other energy resources. The energy resource distribution for 0, 2,4 and 6 per cent annual real interest rates have a similar pattern, but PV contributed a majority of the energy.

This study has used annual real interest and inflation rates dynamic behavior to determine optimal HRES for remote communities. Hence, its analysis will equip decision-makers with the necessary information for accurate planning.

The results of this study can be used to plan and design HRES infrastructure for off-grid communities around the world.

Uzbekistan easily gets 300 days of sunshine a year, and is a natural choice for development of solar technologies and their implementation. Central Asia is working together to solve critical water problems including contamination and dry wells. This chapter addresses the need to find solutions for rural populations living in the shadow of the Aral Sea disaster, with poor quality drinking water and limited infrastructure. With assistance from generous government funding, the Institute for Solar Energy is developing new point-based solar desalinization and pumping technologies. Preliminary designs are promising and government support for raw materials mining and wafer production are growing. Domestic R&D and production ensures cost-effective dissemination options. The Institute houses both research and project management for all solar technologies and expects to field test prototypes within 2–3 years. Solar energy is a growing sector in the economy of Uzbekistan.

This article traces global economic trends and sources of energy from the fossil fuel era of the Industrial Age to the Information and Solar Age. Keynesian economics as well as political, economic and military power, led to the industrialized countries’ petroleum addiction and the demonization of OPEC. The shift from the Old Economy to the New Economy will be accompanied by greater emphasis on energy efficiency and a shift towards renewable resources, “green” energy technologies and environmental protection and restoration. The globalization of economics, finance, markets and trade driven by technology and liberalization of capital flows have led to the dematerialization of OECD economies. This will necessitate recognition of, and investment in, people and social infrastructure with education and health care as key economic sectors and knowledge, intellectual, social and ecological capital as the key factors of production. Due to advances in the internet and e‐commerce and the increasing interchangeability of money with information there will be a continuing flight into pure information‐based electronic trading systems and the growth of a less costly and more efficient pure high‐tech barter system. The issues of unequal terms of trade, poverty and the need for development will continue. If OPEC is able to grasp the significance of the shift to the Solar Age, it has an opportunity to reassert its leadership role in development.

This study aims to focus on the nexus between off-grid systems and impacts on islands and remote villages in Ghana by investigating the sources and cost of energy, willingness to pay for electricity and impacts of off-grid energy on the local economy, education, health, social activities, the environment and migration.

Data were obtained from 110 households; heterogeneous impact analysis of off-grid technologies, average treatment effect by inverse probability weights (IPW) and inverse probability weighted regression adjustment (IPWRA) models were used to analyse the data.

The sources of energy are gas, kerosene, wood fuel and dry-cell battery. All households in communities with neither electricity nor off-grid system were willing to pay for electricity. Households without off-grid systems (US$8.1) were willing to pay higher amounts per month for electricity. The off-grid technologies improve the local economy, social activities, security, the environment, education and health as well as reduce out-migration.

Most of the literature on mini-grid/off-grid systems have been from the engineering and the technical perspective, with a few on the socioeconomic impacts of the systems and consumer engagements. Besides, methods including descriptive statistics, energy technology sustainability framework and qualitative analysis were used in these studies. Nevertheless, the authors used a more rigorous method of the doubly robust inverse probability weighted regression adjustment model and a heterogeneous method to model the impact analysis of off-grid systems.
