Central Africa owns important renewable energy potential. This important potential is still suffering from poor development. The main cause of the poor use of renewable energy is the poor commitment and dedication of governments who have not taken the necessary measures to boost the sector. Thermal plants are hence among other solutions planned or under construction. The purpose of this paper is among other things aiming at ensuring that the renewable energy resources of Central Africa are known and are subject to be used optimally. The work also shows availability of renewable energy sources and suggests actions to promote and sustain its development. Based on the knowledge of the Central African energy sector, this paper will identify actions for improved access to sustainable, friendly, affordable energy services to users as well as a significant improvement of energy infrastructure in Central Africa and the promotion of renewable energy and energy efficiency. The work will show the potential for solar, biomass and hydro while showing where available the level of development. Then identified obstacles for the promotion of clean energy will be targeted. Finally, suggestions will be made to help the countries develop a vision aiming at developing good clean energy policy to increase the status of renewable energy and better contribute to fight against climate change. Cameroon case study will be examined as illustration. We will use several documents from institutions in the region and abroad, and maps when available.

An analysis of the Medium Voltage (MV) electricity power distribution network operated by Cameroon's AES-SONEL company shows that losses are very high due to energy which is produced but not distributed and that the duration of power interruptions as a result of these faults is long due to the time used in searching for the faults. Given that quick detection of faults is a sure means of improving availability and productivity in any company, we hereby propose a system of real-time diagnosis of the faults on AES-SONEL's electric power distribution network. After an inventory of typical faults on electric power networks and the proposal of a tool for their identification, we propose a system for the detection and localization of these various failures. The implementation of the system on a Programmable Logic Controller (PLC) enables the performance of the system to be assessed.
