This paper demonstrates the importance of improving access to and equity in the provision of essential services such as education and health for enhancing human development. A major constraint to accelerating and sustaining economic growth in South Africa is the shortage of skilled human...

Integrated resource planning (IRP) of power generation and delivery characterized by higher penetration of distributed energy resources (DERs) has taken the 21st century world by storm. It promises power markets that are more resilient to resource and capital cost uncertainties as well as...

The need to mitigate the adverse environmental impacts of fossil fuel usage, the volatility of fuel prices and enhancement of national energy security, have largely driven a phenomenal growth, around the world, in renewable energy (RE) generation (particularly grid-connected), over the past two...

Several rural farms have installed anaerobic digestion systems as manure management systems. Such systems are also used to provide electricity and heating. In these systems, biogas is generated from anaerobic digestion of biomass waste and combusted in a boiler and an engine-generator set, to...

We determine the threshold herd size at which a biomass waste to energy conversion system becomes commercially viable. The threshold herd size is found by optimisation of the biomass waste to energy conversion system for different herd sizes. Manure is co-digested with food waste. The...

This paper presents the design of flywheel rotor prototypes developed to enhance rural energisation in sub-Saharan Africa. The flywheel rotors are made from locally available fibre and epoxy resin. The profiles were designed using novel shape profiles based on Berger, Porat and Stodola’s...
