There continues to be significant attention and investment in wind power generation, which can supply a high percentage of the global demand for renewable energy if harvested efficiently. The research study is based on techno-economic analysis of the feasibility of implementing wind power generation in Kuwait with a power generation capacity of 105 MW based on 50 wind turbines, which has a major requirement for clean energy. The study focused on three main areas of analysis and numerical modeling using the RETScreen software tool. The first area involved evaluating the performance and efficacy of generating wind power by collecting, analyzing, and modeling data on observed wind levels, wind turbine operation, and wind power generation. The second area comprised an environmental impact review to assess the environmental benefits of implementing wind power. The third area involved economic analysis of installing wind power in Kuwait. The analysis was undertaken to assess the energy recovery time for wind energy and determine the mitigation of global warming and pollution levels, the decrease of toxic emissions, and any cost savings from implementing clean energy systems in Kuwait. Additionally, sensitivity analysis was undertaken to determine the impact of certain variables in the modeling process. The results are used to estimate that the energy price would be $0.053 per kWh for a power generation capacity of 105 MWh based on an initial cost of $168 million and O&M of $5 million for 214,000 MWh of electricity exported to the grid. Moreover, the wind turbine farm will potentially avoid the emission of approximately 1.8 million tonnes of carbon dioxide per year, thereby saving approximately $9 million over 20 years spent installing carbon capture systems for conventional power plants. The wind farm containing a simple wind turbine is estimated to have a payback period of 9.1 years.

A Techno-Economic Model for Wind Energy Costs Analysis for Low Wind Speed Areas

The global population is moving away from fossil fuel technologies due to their many disadvantages, such as air pollution, greenhouse gases emission, global warming, acid rain, health problems, and high costs. These disadvantages make fossil fuels unsustainable. As a result, renewable energy is becoming more attractive due to its steadily decreasing costs. Harnessing renewable energy promises to meet the present energy demands of the African continent. The enormous renewable energy potential available across the African continent remains largely untapped, especially for wind energy. However, marginal and fair wind speeds and power densities characterize African wind energy resulting in low and unsustainable power in many areas. This research develops a techno-economic model for wind energy cost analysis for a novel, Ferris wheel-based wind turbine. The model is used to techno-economically analyze the siting of wind turbine sites in low wind speed areas on the African continent. The wind turbine’s technical performance is characterized by calculating the annual energy production and the capacity factor using the wind Weibull probability distribution of the cities and theoretical power curve of the wind turbine. Its economic performance is evaluated using annualized financial return on investment, simple payback period, and levelized cost of electricity. The techno-economic model is validated for 21 African cities and shows that the Ferris wheel-based design is very competitive with four current, commercial wind turbines, as well as with other sources of energy. Hence, the new wind turbine may help provide the economical, clean, renewable energy that Africa needs.

“…The conceptual framework that was established in order to answer the research questions is illustrated in Figure 1 below. (Taatila, 2012;Kaunda, 2012;Lumpking & Dess, 2001) along with BP having its two dimensions (Botchkarev, 2015;Paalic & Busattic, 2015) were shown in the above relationship whereas these variables have never been tested earlier in a single model to examine the link between EO and BP.…”

Purpose -Entrepreneurship Orientation is an emerging trend that has attracted much attention presently. This study attempts to examine the relationship between individual Entrepreneurship Orientation and Business Performance among graduate entrepreneurs in the University of Sri Jayewardenepura in Sri Lanka. It is the special intension of this research, to explore this relationship within the context of different theories, models and approaches such as Entrepreneurship Theories, Theory of Planned Behaviour (TPB), Lumpkin and Dess Model and Taatila Model. Methodology -Data collection was done using 109 samples through a questionnaire. The means of descriptive statistics, tests of validity, reliability and the SEM with PLS used for the analysis. Findings -The relationships between BP and Entrepreneurship Desire were (0.163), Innovativeness (0.255), Proactiveness (0.318), Networking Capability (0.264) and Risk-taking (0.062). Conclusion -The relationship between individual EO for the four dimensions and BP is significant and positive while Risk-taking showed the insignificant result.
