This paper presents a review of the current situation and projections for energy access in Africa. The paper also presents several sets of ambitious energy access targets as agreed by the regional groupings within the region. The paper argues that achieving between 50% and 100% access to modern energy services by 2030 in Africa will require more effective mobilization and use of both domestic and external funding, and the development and implementation of innovative policy frameworks. The paper suggests that greater emphasis will need to be placed on productive uses of energy and energy for income generation in order to break the vicious circle of low incomes leading to poor access to modern energy services, which in turn puts severe limitations on the ability to generate higher incomes. The paper further suggests that if anything near the ambitious targets set by African organisations are to be achieved then it will be advisable to tap into the full menu of energy resource and technology options, and there will be the need for significant increases in the numbers of various actors involved together with more effective institutions in the energy sector. © 2009 Elsevier Ltd.

This paper contributes to the effort being made by The Energy Center (TEC), KNUST and African Union Commission to disseminate knowledge of Renewable Energy Technologies (RETs) and as well increase the awareness of the general public especially the youth of Africa in RETs by measuring the average wind speed and direction of a selected project site (designated Site 0001) on the campus of Kwame Nkrumah University of Science and Technology (KNUST). In order to generate a comprehensive wind data report for Site 0001 on KNUST campus a building-integrated hybrid mast (placed at a height of 20 m above ground level), NRG Wind instruments and data retriever as well as Stata, Microsoft Excel and WAsP software were employed. The wind data provided in this paper include monthly and annual average wind speeds, monthly wind gusts, prevailing wind direction and turbulence intensity of air flow among other parameters for Site 0001 on KNUST campus. The wind data made available by this paper can be used by both students and the general public alike for educational and agricultural purposes, air pollution and small wind turbine assessments in Kumasi. © August 2013 IJENS.

There is increasing global attention on the issue of energy poverty. This is evident in the recent priority accorded to universal energy access by the United Nations and the launch of various related multi-stakeholder partnerships. While the exact role of the international community is still being deliberated and refined, there is a need to ensure that robust analytical information is available to decision-makers. © 2012 Elsevier Inc.

In this study, the Network Planner, a decision support tool for exploring costs of different electrification technology options in un-electrified communities, was used to model costs and other inputs for providing electricity to 2600 un-electrified communities in Ghana within a 10-year planning period. The results show that the cost-optimized option for majority of the un-electrified communities will be grid connection, accounting for more 85% of the total un-electrified communities in each region. The total cost of electrification (which includes initial and recurring) at 100% penetration rate totalled US$ 696. million with a breakdown as follows: US$ 592. million for grid electrification, US$ 47. million for off-grid electrification and US$ 58. million for mini-grid compatible communities. Sensitivity analysis shows that model scenarios with higher electricity demand and higher household penetration rate generally recommend a larger percentage of communities for grid electrification, rather than off-grid or diesel mini-grid. One important aspect of this modelling approach is that it predicts costs for different electricity generation technologies for each of the communities involved and thus gives the planner the freedom to explore the most cost-effective technology based on existing conditions in the community and price trend of electrification inputs during the planning period. © 2013 International Energy Initiative.
