Are Biofuels a real alternative for fuel supply in the developing world or just a perception? Bakumbi, Gift; Oladiran, Moses Tunde Most countries in the Southern African subcontinent do not produce oil except Angola, South Africa and the Democratic Republic of Congo (DRC). However, oil is a huge socio-economic growth driver in these countries for industrialisation and transportation. These countries operate on high import bills, growing environmental impacts from greenhouse gas (GHG) emissions and global warming leading to climate change. Studies have revealed that one way of addressing these challenges is through the inclusion of Biofuels in the energy supply mix. However, there are competing and conflicting needs which these developing countries are still grappling with such as sustainable food production and food security. This paper considers the real potential of biofuels in developing countries vis-a-vis food production and security challenges. It estimates the pragmatic biofuel production levels that can be achieved without creating food production conflict.

The pros and cons of ban on coal energy: way out for Africa Oniyide, Gafar, O. Coal usage has contributed immensely to evolution of general manufacturing, iron and steel production, power generation, railways and other industries. Apart from its usage in the industries, coal mining is also an important source of income for many countries. The call for world transition from coal to renewable energy has been on for some times in the past. This is because coal is considered one of the most green-house-gas intensive sources of electricity. This paper, therefore, investigates the pros and cons of banning coal as a source of energy generation. The data used in this study were mostly sourced from the literature. The study reveals that China, the United States, India, Russia, Japan, Germany, South Africa, South Korea, Indonesia and Poland are the top ten top countries in the world using coal energy. The findings also show that the cons outweigh the pros. It is recommended that African countries whose main source of energy generation is from coal should endeavour to reduce its environmental impact through coal liquefaction and gradual phase-out of coal fired plants.

Simulation of energy consumption in hybrid electric vehicles used in a semi arid region: A case for Palapye, Botswana Motsomi, Matthias O. T.; Oladiran, Moses Tunde Electric vehicles are renowned for their merits such as reduced pollution, no emission and small reliance on non-renewable fossil fuels, yet their adoption is low. The low adoption of electric vehicles is due to their disadvantages such as low range, long charging hours and some potential consumers have the fear of running out of charge while driving. A prediction of the energy consumption of an electric vehicle helps to alleviate such fear. In this work simulation results are presented which compare the energy consumption of a Toyota Prius, a hybrid electric vehicle modeled in ADVISOR simulation package, when used under summer European and Palapye Botswana ambient conditions respectively. The New European Driving Cycle was used and ambient conditions were varied in the input parameters. Results show that the state of charge are respectively 50% and 54% under hotter conditions of Palapye and a European country. The gradient of the state of charge of the battery pack during the simulation period is also steeper for Palapye conditions than for a European country which shows that energy is consumed at a higher rate in the former. Based on the difference in the state of charge for both conditions, results show that there was an 8% higher energy consumption under Palapye’s conditions. The results can inform consumers on what to expect when purchasing and operating a hybrid electric vehicle. Results also provide a guide for the design of electric vehicles intended for use in a semi-arid country such as Botswana. It can be concluded that electric vehicles consume more energy under harsher or more hostile environmental conditions owing to the use of auxiliary systems such as air conditioners and other temperature control systems. Future research work needs to develop better battery storage systems and driving cycles that accurately model conditions in hot climate regions.
