Research ArticleOpen accessIn the abstractEnvironmental Protection through Nuclear EnergyFlorian Ion T. Petrescu, Antonio Apicella, Relly Victoria V. Petrescu et al.Environmental protection through implementation of green energies is progressively becoming a daily reality. Numerous sources of green energy were introduced in recent years. Although this process initially started with difficulties, it finally resulted in an acceleration and implementation of new green energy technologies. Nonetheless, new major obstacles are emerging. The most worldwide difficult obstacle encountered, especially for wind and photovoltaic … …American Journal of Applied Sciences, Vol. 13, Issue 9 · 28 Sep 2016 · 12,504 accessesView PDFCite
EditorialOpen accessIn the abstractAn Opportunity for the Agricultural Sector: The Renewable Energy SourcesRiccardo Testa, Salvatore TudiscaToday, among the most important issue for energy decisions by policymakers, there are security challenges and environmental impacts on climate change and economic aspects. Since the seventies, in fact, global warming and environmental issues have had an increasing importance in international debate, attracting the attention of several scientific studies (Landi and Benelli, 2016). Many of these studies denoted that over … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 6 Sep 2016 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of the Edges of a Backside Diffusive Reflector on the External Quantum Efficiency of Luminescent Solar Concentrators: Experimental and Computational ApproachMauro Pravettoni, Cristina S. Polo Lòpez, Robert P. KennyLuminescent Solar Concentrators (LSCs) have been proposed in the 1970s as cheap planar concentrators for residential applications and nowadays represent a novel idea with excellent perspectives for building integration photovoltaics. The interest in LSCs has increased in the last years, due to improved stability of luminescent dyes, the introduction of quantum dots and nanorods and the overall reported increase in … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Jan 2016 · 8,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Dynamic Simulation of a Combined System Integration Concentrating Photovoltaic/Thermal Solar Collectors and Organic Rankine CycleFrancesco Calise, Massimo Dentice d'Accadia, Maria Vicidomini et al.This study presents the design of a novel ultra-high efficient solar power system. The system is equipped with a concentrating PhotoVoltaic/Thermal (CPVT) solar collectors bottomed by an Organic Rankine Cycle (ORC). The basic idea is to use a high temperature CPVT device producing simultaneously electricity and hot diathermic oil. Then, this hot fluid is used to supply heat to the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 17 Apr 2015 · 8,654 accessesView PDFCite
EditorialOpen accessIn the abstractON THE CHALLENGES OF THE USE AND INTEGRATION OF RENEWABLE ENERGY SOURCESMariano MartínOverview: Although renewable energy sources are plentiful, their availability is highly volatile in time and distributed across regions while and the processes that transform them into useful power or chemicals are underdeveloped. In this work we discuss on the scope for the use and integration of renewable energy sources and the future development of the alternatives. Energy, the sources and … …Energy Research Journal, Vol. 5, Issue 1 · 11 Sep 2014 · 7,540 accessesView PDFCite
EditorialOpen accessIn the abstractRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractGlobal Solar Radiation Studies Due to Sunshine Hours and Other Meteorological ParametersMfon David Umoh, Sunday O. Udo, Ye-Obong N. UdoakahMultiple linear regression models were developed to estimate the monthly daily Sunshine Hours using four parameters during a period of eleven years (1997-2007) for locations in South Eastern Nigeria. These locations include Uyo (Latitude 5°18'53.7"N), Calabar (Latitude 5°16'07.6"N), Port Harcourt (Latitude 4°56'26.2"N), Warri (Latitude 5°34'21.0"N), Enugu (Latitude 6°27'42.42"N), Owerri (Latitude 5°38'05.1"N). The parameters include Relative Humidity, Maximum and Minimum temperatures, … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 30 Sep 2013 · 7,700 accessesView PDFCite
