Wind Speed Increase

The wind energy sector is one of the most prominent sectors of the renewable energy industry. However, its dependence on meteorological factors subjects it to climate change. Studies analysing the impact of climate change on wind resources usually only model changes in wind speed. Two elements that have to be calculated in addition to wind speed changes are Annual Energy Production (AEP) and Power Density (PD). This is not only because of the inherent variability between wind speed and wind power generated, but also because of the relative magnitudes of change in energy potentially generated at different areas under varied wind climates. In this study, it was assumed that two separate locations would experience a 10% wind speed increase after McInnes et al. (2010). Given the two locations’ different wind speed distributions, a wind speed increase equal in magnitude is not equivalent to similar magnitudes of change in potential energy production in these areas. This paper demonstrates this fact for each of the case studies. It is of general interest to the energy field and is of value since very little literature exists in the Southern African context on climate change- or variability-effects on the (wind) energy sector. Energy output is therefore dependent not only on wind speed, but also wind turbine characteristics. The importance of including wind power curves and wind turbine generator capacity in wind resource analysis is emphasised.

Development And Validation

The present study develops, refines and validates a scale to measure e-service quality. A total of 545 respondents were approached and employed EFA and CFA. Potential items were drawn from relevant literature. The developed e-service quality scale has six dimensions, namely: information quality and usability, reliability, security and privacy, efficiency, system availability and assurance. The findings reveal that information quality and usability was the most significant factor, followed by reliability in contributing to e-service quality. Practitioners may utilize the scale to measure e-service quality and take steps to bridge the gap between customer expectations and perceived quality.

Development And Validation

The retail industry remains one of the largest sectors in the global economy. In South Africa, retailing is one of the toughest and most competitive industries. The South African retail business environment is becoming increasingly hostile and unforgiving, with intense competition from both domestic and foreign companies (Terblanche, 1998: 1). The findings of this preliminary study do provide basic support for a three-factor structure for supermarket service quality in terms of reliability and validity. The reliability analysis, which followed the factor analysis, reflected coefficient α values ranging from 0.85 to 0.90, indicating high internal consistency among variables within each dimension. In today's saturated retail markets, retailersface increasing hurdles to attract and maintain customers.

Purpose There is increasing research interest in the expansion of the offshore wind energy sector. Recent research shows that operations and maintenance (O&M) account for around 20-35 per cent of the total energy costs in this sector. The purpose of this paper is to provide an overview of O&M issues in the offshore wind energy sector to propose initiatives that can help reduce the cost of energy used by offshore wind farms. Design/methodology/approach The paper is based on an in-depth literature review and a Delphi study of a panel of 16 experts on O&M. Findings Consisting primarily of conceptual papers and/or modelling papers, the extant literature identifies several challenges for O&M in the offshore wind energy sector. These challenges can be grouped into four categories: issues related with industry immatureness; distance/water depth; weather window; and policy issues. The Delphi study identified three other major issues that lead to increased O&M costs: too many predefined rules that limit development; lack of coordinated planning of the different services offered at the wind farms; and lack of a common approach on how O&M should be managed strategically. Research limitations/implications The present study is based only on Danish respondents. Future research needs to include various respondents from different countries to identify country-specific contingencies. Practical implications The paper provides an overview of the O&M issues in the offshore wind energy sector to prioritize where future resources should be invested and, thus, reduce O&M costs. Originality/value This is the first paper on O&M issues that bridges both literature studies and industry expert opinions.
