Energy was not stated as one of the millennium development goals (MDGs) but played an indirect role in helping meet the MDGs especially in the areas of housing, health, education, and poverty reduction in Africa. In contrast, the United Nations’ 2030 agenda includes 17 sustainable development goals (SDGs), one of which is devoted to energy. SDG7 seeks to ensure “access to affordable, reliable, sustainable, and modern energy for all,” thereby creating a vital role for the energy sector to join in the task of achieving SDGs. Renewable energy including solar energy will play a significant role in improving energy security in Africa and diversifying the energy mix by reducing reliance on fossil fuels. This chapter examines the advantages of solar technologies in the context of social, economic, and environment benefits using case studies from Kenya and South Africa. This chapter also examines some of the key challenges that are associated with the application of solar energy technologies in these countries. Finally, the chapter discusses how solar energy technologies can help meet SDGs and summarizes policy and programs targeting the promotion of solar energy technologies for the implementation of SDGs.

The purpose of this study is to identify the most relevant renewable energy technologies for buildings and to assess the effectiveness of their implementation in the long term for Kuwait. Methods of analogies and comparisons were used to determine the features of energy efficiency based on the technologies under study. The study proposes the methodological approach to assessing the effectiveness of the introduction of renewable energy technologies, determining the direction of increasing the energy efficiency of buildings and the investment efficiency of introducing these technologies. Renewable energy efficiency analysis for buildings in Kuwait confirms that solar energy systems have been the most widely available for widespread use of solar energy over the past three years. An increasing level of energy efficiency with a decrease in the notional cost of increasing energy savings is characteristic of solar collectors with booster reflectors. The proposed model for assessing the level of energy saving provides an opportunity for economic justification of introducing renewable energy technology in buildings.

Abstract This paper develops an integrated framework to study the socio-spatial and temporal dimensions of urban energy transitions to investigate the development and spread of solar energy technologies in urban China. A comparative analysis of three case studies of solar energy transitions in the cities of Foshan (in Guangdong), Rizhao (in Shandong), and Wuxi (in Jiangsu) demonstrates the framework’s applicability. The results map each city’s trajectory towards low carbon energy. Transitions result from dynamic interactions among central and local governments, solar manufacturers, solar installers, and residents. Alongside industrial strategies, locally-specific factors have a determining influence on the eventual outcomes.
