A stand-alone system is defined as an autonomous system that supplies electricity without being connected to the electric grid. Hybrid systems combined renewable energy source, that are never depleted (such solar (photovoltaic (PV)), wind, hydroelectric, etc.) , With other sources of energy, like Diesel. If these hybrid systems are optimally designed, they can be more cost effective and reliabl...

Natural energy reserves like petrol and diesel etc are depleting as such it is of paramount importance to find alternative fuels. Solar energy is traped as biomass in plants. Biomass provide an excellent reserve for traping solar energy on field. Complex enzymatic machinery comprising of hydrolytic reactions and consolidated bioprocessing is needed to make viable bioenergy mostly biofuels like ...

Due to disperse nature of renewable energy resources (RES), electricity generation is often taking place in small scale but main drawback is power quality. So to improve power quality issues, integration of renewable energy into the utility grid can be done either at transmission level or the distribution level depending on the scale of generation. The renewable resources like solar energy, win...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...

A solution filling and drying method has been demonstrated to fabricate Si/PEDOT:PSS core/shell nanowire arrays for hybrid solar cells. The hybrid core/shell nanowire arrays show excellent broadband anti-reflection, and resulting hybrid solar cells absorb about 88% of AM 1.5G photons in the 300–1100 nm range. The power conversion efficiency (PCE) of the hybrid solar cell reaches 6.35%, and is p...

Energy consumption in the buildings is responsible for 26% of Australia’s greenhouse gas emissions where cooling typically accounts for over 50% of the total building energy use. The aim of this study was to investigate the potential for reducing the cooling systems’ environmental footprint with applications of alternative renewable energy source. Three types of cooling systems, water cooled, a...

In Environmental friendly solutions are becoming more eminent than ever as a result of concern regarding the state of our worsen planet. This paper presents a modeling of solar and fuel cell hybrid isolated full bridge converter for electric vehicle driving system. The HFT (high frequency transformer) initiate in isolated full bridge boost converter for precipitate power conversion of photo vol...

Bioenergy cropping systems could help offset greenhouse gas emissions, but quantifying that offset is complex. Bioenergy crops offset carbon dioxide emissions by converting atmospheric CO2 to organic C in crop biomass and soil, but they also emit nitrous oxide and vary in their effects on soil oxidation of methane. Growing the crops requires energy (e.g., to operate farm machinery, produce inpu...
