To tackle climate change and secure energy supplies, many countries invest heavily on wind energy as it is a clean source and is becoming more cost effective with the technological advancement and increased capacity per unit installed. The investigation of the availability of wind resources is an essential step of any feasibility study of a wind farm project and is vital for securing financial resources. With this intent, the main aspects for designing a wind farm at Ajloun (north of Jordan) is investigated and wind energy potential is determined based on available wind data. Based on the site characteristic, the required infrastructure is highlighted, including the turbine array layout and the pattern of connections with the external transmission lines. The investigation of the feasibility of the project includes an appraisal of social and environmental consequences of constructing the wind farm project. The results show that the selected location for the wind farm is encouraging and has a promising profit potential. The findings estimate the annual electricity generation of the wind farm at 379659.51 MWh, with a breakeven selling point of around $30.03/MWh, at a highly competitive price. However, with an estimated selling price of $36.65/MWh on average, it will settle the interest rate demanded by the banks that have an internal rate of return of 7%. No major issues with geotechnical and environmental issues were identified with respect to the project.
Using renewable energy sources provides a promising solution to minimize the overuse of conventional energy sources as well as to reduce pollution. Biogas technology is one solution that offers the conversion of waste streams to a renewable source of higher value. Anaerobic digestion of organic waste from industrial processes produces energy in the form of biogas, which has an advantage of preventing odor release, and has minimal pathogens. In this study, two different sources of bio-waste were investigated for their biogas potential, namely palm date waste and olive pomace. All of the samples produced biogas; however, the amount produced was only 20% to 40% of what conventional substrates typically produced. Producing biogas that uses only olive biomass offers a solution to the waste disposal problem, but it is not efficient for biogas production. For optimal heat utilization and maximizing biogas production, mixing of different feedstock was identified as a valid solution. Hence, a model of mixing other sources of bio-waste, such as chicken manure, can activate sludge and is proposed to boost the biogas production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
