Generating energy by means of renewable sources is a vital strategy for all the Gulf Cooperation Council (GCC) countries. Photovoltaic (PV) systems in the GCC have been a primary choice among renewable sources due to regional weather and high levels of irradiance. However, unfavourable environmental factors such as high temperatures, soiling and dust have been a concern for PV performance. Offshore

In this paper, the effect of the number of blades on the optimal energy utilisation efficiency for a modified Savonius rotor with rotor diameter of 4 m is investigated by computational fluid dynamics simulation using a uniform test method. The appropriate computational domain of a numerical model is determined by first analysing the relative error of the outlet wind velocity on the outflow boundary

A large interdisciplinary consortium of engineers, social scientists and policy analysts has developed three low-emissions, more-electric transition pathways for the UK. The approach is based on earlier work on understanding transitions, applying a multi-level perspective with landscape, regime and niche levels to the development of socio-technical scenarios. The pathways to 2050 focus on the power

Chernobyl – History of a Tragedy

The residential sector holds significant potential for improvements in energy efficiency in Ireland. Retrofit activity, however, can be difficult to instigate despite the presence of government incentives and cost-effective investment opportunities. The failure of individuals and organisations to invest in cost-effective energy efficiency measures is often referred to as ‘the energy efficiency gap’

Thermochemical heat-storage materials such as magnesium, zinc and iron sulfates offer high energy-storage densities and a reliable means of long-term storage of solar energy. In this research study, the dynamic properties of these three salts were investigated based on their hydration and dehydration characteristics. To investigate the effect of regeneration temperatures on the physio-chemical properties

Considering the importance of energy for social and economic development, access to clean, affordable and reliable energy has been adopted as one of the United Nations sustainable development goals that all countries aim to achieve by 2030. However, much of the world's energy is still produced from fossil fuels and thus the progress towards clean and renewable energy is slow. This paper explores the

Located in between the Flores and Adonara islands, Larantuka Strait has one of the strongest tidal currents in Indonesia. A bridge 810 m long is planned to be constructed across the strait to connect the islands. The Palmerah Tidal Bridge project, commenced in 2019, is planned to be the first combined tidal energy/bridge project worldwide. By combining the installation of turbines with bridge construction
