This paper evaluates a novel receiver design concept that implements photovoltaic (PV) cells on heat shields and bellows shields to capture optical spillage from central receiver and parabolic trough concentrating solar power (CSP) plants, generating electricity from concentrated light that would otherwise be wasted. A combination of conventional silicon and multi-junction concentrating PV (CPV...

The main objective of this work is to design an optimal—efficient economic power renewable energy system that feeds the required electric load of a small scale brackish reverse osmosis desalination unit and a tourism motel located in Hurghada, Egypt. Four renewable energy power systems are presented in this paper to select the most optimum one of them. These suggested renewable energy systems a...

The retail price a household pays for the last unit of grid-supplied electricity consumed is an important driver of the decision to install a rooftop solar photovoltaic (PV) system. This price is the cost a household avoids by consuming a kilowatt-hour (KWh) from their rooftop solar system. Consequently, if the levelized cost of a KWh from a rooftop solar system is less than this retail price, ...

The main objective of this study is to discuss the economical and the environmental analysis of a net zero energy (NZE) tourist village in Alexandria, Egypt, by maximizing the renewable energy fraction and minimizing the greenhouse gases (GHG) emissions. The hybrid photovoltaics (PV)/wind/diesel/battery system is found to be the optimum hybrid renewable energy system (HRES) for the proposed tou...

Abstract It is expected that lightweight drive train systems for large wind turbines can reduce overall levelized cost of energy (LCOE) compared to conventional designs, particularly through a less robust and therefore lower-cost turbine substructure. Representing major share mass, the focus mass reduction efforts concentrate on generator. In order assess influence specific generator designs LC...

ultra-endurance mountain running has become extremely popular in recent years, and the energy cost is one of the factors that influence the final performance. the aim of this study was to determine if the energy cost of uphill running (uphill cr) can be calculated from level cr (energy cost of running in mlo2.kg-1.mn-1) in a heterogeneous group of mountain ultra-endurance runners using the di p...
