Indonesia and South Africa are both trying address energy poverty through subsidized energy provision. South Africa has implemented one of the largest electrification programmes in the world, and 80 per cent of the population now have access to the national grid. But this alone is unlikely to achieve universal energy access goals. Indonesia recently implemented one of the largest household energy transition projects to date: the kerosene-to-LPG (liquid petroleum gas) conversion programme. Exploring these projects makes more visible the political economic factors that have affected the adoption of certain energy carriers.

Recently, energy access and efficiency have attracted much research interest due to their critical role in addressing the challenges of climate change and the country’s social and economic development. The major question in this study is whether household energy demand can be influenced by government institutions and political systems which switch their preferences towards clean energy sources including renewable energy. The analysis revealed that government agencies are not well-coordinated when dealing with energy access and efficiency issues e.g., ward and village leaders are not always in agreement and lack common understanding of issues arising out of increasing energy supply and use of energy efficient appliances. In addition, households witnessed that despite their low level of income, they would have done better in terms of accessing quality and affordable energy had they been educated or informed about the need to shift from using wood to electricity for different social and economic activities. The study recommends that universities offer training, research and consultancy in the energy field to help raise awareness among communities of costs and benefits of using clean energy sources. The results therefore, provide useful and current information to policy making and energy planning institutions on the barriers to energy access and efficiency in order to help formulate remedial action.

Nowadays, the most decisive challenges we are fronting are perfectly clean energy making for equitable and sustainable modern energy access, and battling the emerging alteration of the climate. This is because, carbon-rich fuels are the fundamental supply of utilized energy for strengthening human society, and it will be sustained in the near future. In connection with this, electrochemical technologies are an emerging and domineering tool for efficiently transforming the existing scarce fossil fuels and renewable energy sources into electric power with a trivial environmental impact. Compared with conventional power generation technologies, SOFC that operate at high temperature is emerging as a frontrunner to convert the fuels chemical energy into electric power and permits the deployment of varieties of fuels with negligible ecological destructions. According to this critical review, direct ammonia is obtained as a primary possible choice and price-effective green fuel for T-SOFCs. This is because T-SOFCs have higher volumetric power density, mechanically stable, and high thermal shocking resistance. Also, there is no sealing issue problem which is the chronic issues of the planar one. As a result, the toxicity of ammonia to use as a fuel is minimized if there may be a leakage during operation. It is portable and manageable that can be work everywhere when there is energy demand. Besides, manufacturing, onboard hydrogen deposition, and transportation infrastructure connected snags of hydrogen will be solved using ammonia. Ammonia is a low-priced carbon-neutral source of energy and has more stored volumetric energy compared with hydrogen. Yet, to utilize direct NH3 as a means of hydrogen carrier and an alternative green fuel in T-SOFCs practically determining the optimum operating temperatures, reactant flow rates, electrode porosities, pressure, the position of the anode, thickness and diameters of the tube are still requiring further improvement. Therefore, mathematical modeling ought to be developed to determine these parameters before planning for experimental work. Also, a performance comparison of AS, ES, and CS- T-SOFC powered with direct NH3 will be investigated and best-performed support will be carefully chosen for practical implementation and an experimental study will be conducted for verification based on optimum parameter values obtained from numerical modeling.
