This paper proposed an intelligent approach to predict the biochar yield. The biochar is an important renewable energy that produced from biomass thermochemical processes with yields that depend on different operating conditions. There are some approaches that are used to predict the production of biochar such as least square support vector machine. However, this approach suffers from some drawbacks...
Access to energy is one of the primary cause contributing to the disparity between developed and developing nations. Nearly 600 million people in Africa lack access to electricity which majority of them residing in the sub-Saharan African (SSA) countries. Electricity consumption in SSA countries excluding South Africa is 153kwh/year. The current installed capacity is at 147 GW which is equivalent...
Accurate and detailed energy demand estimates are crucial to achieving adequate energy infrastructure planning. These estimates are often non-existent or deficient in many developing countries, and consequently, electricity supply is unreliable. A novel approach for estimating electricity demand is presented. Our approach uses a global geographical population database with 1km2 spatial resolution...
An energy audit has been conducted for the Dedza district in Malawi, which required the development and implementation of a multidisciplinary options appraisal methodology involving a literature review; solar, wind and hydro resource assessment; household and business surveys; focus group discussions and expert interviews. A decision making tool was developed to score and rank renewable energy technologies...
This paper presents the results of a survey conducted to determine the extent of students' awareness of energy conservation measures in the use of various electrical appliances as well as their preparedness to support efforts towards reducing energy wastage in institutions. The survey was carried out through the administration of questionnaires. Nine hundred and seventy questionnaires were administered...
Southern African countries to this day remain one of the regions with the lowest electricity access rates, particularly in rural areas. The main reason for the low rate of services is the distance between these communities and the electricity grid. In many cases extension of the grid to rural communities is difficult due to high costs. Off-grid power systems are self-sufficient electrical networks,...
