Energy security, uncertainty, and energy resource use option in Ethiopia : a sector modelling approach
Guta, Dawit Diriba; Börner, Jan - 2015
Ethiopia’s energy sector faces critical challenges to meeting steadily increasing demand given limited infrastructure, heavy reliance on hydroelectric power, and underdevelopment of alternative energy resources. The main aim of this paper is to investigate an optimal least cost investment...

Site assessment, turbine selection, and local feed-in tariffs through the wind energy index
Ritter, Matthias; Deckert, Lars - 2015
Since wind energy is rapidly growing, new wind farms are installed worldwide and a discussion is going on concerning the optimal political framework to promote this development. In this paper, we present a wind energy index, which is supportive for wind park planners, operators, and...

The impact of climate change on wind and solar resources in southern Africa
Fant, Charles; Schlosser, C. Adam - 2013
Climate change is an issue that requires global attention and co-operation. As climate science develops an understanding of changes to the future climate state, policy makers and engineering project planners beg to know what claims can be made on the subject with a reasonable level of...

Designing an index for assessing wind energy potential
Ritter, Matthias; Shen, Zhiwei; López Cabrera, Brenda; … - 2014
To meet the increasing global demand for renewable energy such as wind energy, more and more new wind parks are installed worldwide. Finding a suitable location, however, requires a detailed and often costly analysis of the local wind conditions. Plain average wind speed maps cannot provide a...

Planning for large-scale wind and solar power in South Africa : identifying cost-effective deployment strategies through spatiotemporal modelling
Ummel, Kevin; Fant, Charles - 2014
South Africa hopes to expand wind and solar power. Success depends on how and where to deploy the technologies. This study develops a 10-year database of expected power generation for these technologies across South Africa. A power system model simulates the performance of different spatial...

A Greenfield model to evaluate long-run power storage requirements for high shares of renewables
Zerrahn, Alexander; Schill, Wolf-Peter - 2015
We develop a dispatch and investment model to study the role of power storage and other flexibility options in a … up to a renewable share of around 80%, as other options on both the supply side and demand side also offer flexibility at … requirement strongly depends on the costs and availability of other flexibility options, particularly on biomass availability. We …

Default risks, moral hazard, and market-based solution : evidence from renewable energy market in Bangladesh
Hossain, Monzur; Yoshino, Naoyuki; Taghizadeh-Hesary, Farhad - 2019
This paper analyzes a unique case of default risks and associated factors of a solar home system (SHS) program in Bangladesh and, within that context, proposes a theoretical market-based solution to finance a renewable energy (RE) program. The paper first develops a theoretical framework that...

Intermittency or uncertainty? : impacts of renewable energy in electricity markets
Weber, Paige; Woerman, Matt - 2022
Renewable energy resources possess unique characteristics-intermittency and uncertainty- that pose challenges to electricity grid operations. We study these characteristics and find that uncertainty, represented by wind forecast error, has larger grid impacts than intermittency, or hourly...

Energy and emissions conflicts in urban areas
Conde, Touria Abdelkader B. - 2014
The main aim of this paper is to observe the environmental behaviour in some cities of the word, by analyzing for each city the trends of several energy and emissions indicators that appear as explanatory variables in both energy and labour average productivity equations. At the same time we...
