ABSTRACT This study focuses on examining the long run relationship and granger causality between economic growth, carbon emissions, energy consumption, in Zambia from 1980 to 2017. The study employs Johansen cointegration technique, Vector error correction model (VECM), error correction-based...

The aim of this research is to facilitate informed decision making for an optimal cost-based allocation of future electricity generation resources in Zambia. Such a study is cardinal in order to find out which energy technologies are economically viable from a long-term perspective for our...

As the population of Zambia is growing bigger, so does the demand for energy. Currently, Zambia is dependent on ZESCO as the main producer of electricity for the Zambian people. Despite the government liberalising the energy sector in 1997, very few private players have come on board. ZESCO has...

One of the major problems in concentrating solar radiation on the Photovoltaic (PV) module is the uneven illumination of the solar cells. The non – uniform irradiance creates hot spots on the module and increases its temperature. The high temperature results in a lower efficiency and increases...

The aim of this study was to carry out an experimental investigation on drying fresh Kapenta (Stolothrissa tanganicae), in a Greenhouse Solar Dryer and to evaluate a suitable thin-layer drying model for fresh Kapenta. The nutritional constituents and quality of dried Kapenta produced from a...

The traditional high concentrating photovoltaic systems have proved to be expensive as they use high grade silicon solar cells, highly specular reflecting materials and require tracking arrangements which are equally expensive. The problem of un-even illumination creates heat-sinks which have not...

The production of energy from fossil fuels and nuclear materials has environmental drawbacks. These drawbacks include the creation of nuclear waste and the pollution associated with fossil fuels which lead to global warming and climate change. It is apparent that alternative and sustainable...

A high absorptance (>0.90) is an essential factor in the efficient use of a .solar collector. However, equally important is the need to keep the emittance as low as possible (<0.20). Both the.absoptance and emittance depend on the optical properties of the coating and the substrate. The solar...

A numerical model for determining the size of a forced - convection solar fish dryer comprising of a drying bin (in which the fish is kept), aflat plate solar collector and a fan, has been developed. The model comprises of two sections with the first section calculating the technical parameters...
