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 study aimed to generate informative data on solar radiation in order to establish sustainable solar energy that will support domestic needs and agricultural production and processing industries in Jubek State, South Sudan. Solar radiation intensity, timely data variation, site landscape, and environment were considered. Input data used was remotely sensed data, digital elevation model, land used land cover (LULC) processed with Aeronautical Reconnaissance Coverage Geographic Information System (ArcGIS). The spatio-temporal distribution analysis results show that (62%) 11,356.7 km2 of the study area is suitable for solar energy farm with an annual potential of about 6.05 × 109 GWh/year out of which only 69.0158 GW h/year is required to meet the local demand of 492,970 people residing in the study area, i.e., 0.11% (1249.2 km2) of Jubek State. Solar energy required for producing and processing 1 ton of different crop ranges between 58.39 × 10−6 and 1477.9 × 10−6 GWh and area size between 10.7 and 306.3 km2, whereas 1 ton of animal production requires solar energy ranging between 750.1 × 10−6 and 8334 × 10−6 GWh and area of about 137.8 to 1531.5 km2. These findings will assist in the establishment of agro-processing industries which will eventually lead to poverty reduction through job creation and improvement of food quantity and quality. The simple approach applied in this study is unique, especially for the study area, thus it can be applied to some other locations following the same steps.

Solar energy is a kind of renewable energy, it‘s abundant, clean and environmental protection. In the current theme that calls for saving energy and reducing pollution, it’s undoubtedly of great significance to make full use of solar energy. In order to effectively use solar energy, we developed an automatic sunlight tracking solar panel system based on single chip microcomputer. We use MC9S12XS128 single chip microcomputer as the main control chip, and acquire signal with the sensor composed of photoconductive resistances. According to the signal collected by sensors, the control signal drives step motor to rotate, so that the system can follow the sun, ensuring that solar panel is always vertical to the sunlight, so it can absorb and convert solar energy to the maximum extent.

The present scenario of energy conservation has witnessed many innovative and eco-friendly techniques and one such area where there is a necessity to conserve energy is foundries. Foundries also pollute the atmosphere with greenhouse gases contributing to 296143037.6 metric tons annually. The proposed technique in this paper aims at reducing the energy utilized in melting the scrap material at foundries by solar thermal energy. In the methodology proposed, solar energy is concentrated onto the scrap placed on a receiving platform using a parabolic trough and heats it up so that the heated scrap takes lesser energy to melt. The experiments resulted in preheating temperature of 100 °C when placed on a receiving platform and 110°C when copper shots are used to conduct heat from receiver to the scrap. This translates to energy conservation of 6%. This eco-friendly technique when adopted can result in substantial savings in consumption and environmental protection.

Because the refrigerant can cause serious damage to the ozone layer and form the greenhouse effect, developing green environmental protection refrigeration technology has become a consensus. Based on the view, this paper puts forward a new device called the solar energy driven VM cycle heat pump which used the natural working materials—nitrogen as the refrigerant and the clean energy—solar as the driven energy. According to build the thermodynamic model, the influence of heat source temperature on the ideal cycle has been analysed. And COP of the solar driven the VM cycle heat pump will be received. With the city of Beijing, for example, the device refrigeration COP can reach at least 1.4.

Solar powered intellective vehicles (SPIVs) not only focus on energy saving and environmental protection, but also have finer feasibility. The design of extended range in SPIVs is a kind of the important directions that low carbon green vehicles will be design in future. We will reflect demanding design of extended range shoot to convert the target design level. The optimal design is actualized for photovoltaic array collocation of solar energy in SPIVs. The “zero oils consume, zero exhaust, increment drives distance” demand of SPIVs are carry out by the vehicle with design carries to net electrical source system of extended range.
