Solar photovoltaic (PV) technology can provide sustainable power for the growing global population in cities, but it demands considerable land area. This is a challenge for densely populated cities. However, the stranded assets of non-productive parking lots areas can be converted to solar farms with PV canopies, enabling sustainable electricity generation while preserving their function to park automobiles. This study provides a method for determining the technical and economic potential for converting a national scale retail company’s parking lot area to a solar farm. First, the parking lot area for the company is determined and divided into zones based upon solar flux using virtual maps. Then the potential PV yield in each zone is calculated. A sensitivity analysis is performed on the price per unit power installed, solar energy production as a proxy for conversion efficiency, electricity rates and revenue earned per unit area. To demonstrate this method, analysis of Walmart Supercenters, USA is presented as a case study. The results show solar canopies for parking lot areas are a profitable as well a responsible step in most locations and there is significant potential for sustainable energy deployment in cities by other similar retailers using solar PV canopies.

Sediment microbial fuel cells (SMFCs) can generate electricity without maintenance in the field. SMFC is considered as an alternative renewable and sustainable power source. Though the SMFC is very appealing energy source, it presents certain challenges for real applications. Its output voltage and current are very low and its output voltage cant be increased by stacking several SMFCs in series in an open water body such as the lake. In this research, we construct and simulate a field SMFC with sediment from Xuanwu Lake in Nanjing, China. Open-circuit voltage of the SMFC is 750 mV and the maximal power density is 7.8 mW/m2. A custom-designed power management system (PMS) is developed to harvest energy from SMFC and boost the output power that can drive a wireless sensor. With the PMS, wireless sensor can utilize the harvested energy from SMFC and transmit data to computer without additional power source.

ABSTRACTIn addition to the piezoelectric nanogenerators and triboelectric nanogenerators, recently, the graphene-based nanogenerator has been widely concerned because of its simple assembly, flexibility and high structural stability. There are many interesting effects in graphene applied for nanogenenrators including anion adsorption in electrolyte solution, ion channels in graphene sheets network and the strain (band engineering) effect, etc. In this paper, we focus explicitly on the experimental results, mechanisms and applications of the graphene-based nanogenerator, and introduce our recent research on the graphene-based nanogenerator based on "modulation of the graphene strain-energy band effect". This nanogenerator is expected to have potential applications in active sensors and sustainable power source.

Nitrogen fixation is a standout amongst the most significant concoction responses in the biological system of our planet. Under the regularly pressure of the petroleum product exhaustion emergency and anthropogenic worldwide environmental change with ceaseless CO2 emanation in the 21st century, examine focusing on the union of NH3 under gentle conditions in an economical and condition agreeable way is lively and flourishing. Thusly, the focal point of this survey is the cutting edge designing of effective photocatalysts for dinitrogen (N2) obsession toward NH3 amalgamation. Creating green and feasible techniques for NH3 combination under surrounding conditions, utilizing sustainable power source, is firmly wanted, by both modern and logical scientists. Photosynthesis for ammonia synthesis, which has as of late pulled in noteworthy consideration, straightforwardly creates NH3 from daylight, and N2 and H2O by means of photocatalysis. Photocatalysts containing copious surface oxygen-opportunities and coordinative unsaturated metal locales have been demonstrated to be equipped for actuating N2 reduction under fitting photoexcitation. A few impetus materials are examined which incorporate metal oxides, metals sulfides, carbon-based impetuses, and metal nitrides which are for the most part right now being sought after for their better use of their synergist property towards nitrogen fixation. This chapter portrays the photocatalytic reduction systems of nitrate towards unwanted items (nitrite, ammonium) and the more alluring item (dinitrogen).

The target of this paper is to propose a Multi-input control converter for the cross breed framework so as to disentangle the power framework and lessen the expense. Sustainable power source advancements offers perfect, rich vitality accumulated from self re-establishing assets, for example, the sun, wind and so forth. As the power request expands, control disappointment additionally increments. Along these lines, sustainable power sources can be utilized to give steady loads. Another converter topology for half breed wind/photovoltaic vitality framework is proposed. Hybridizing sun oriented and wind control sources give a practical type of intensity age. The topology utilizes a combination of Buck converters. This design enables the two sources to supply the heap independently or at the same time contingent upon the accessibility of the vitality sources. Reproduction is done in MATLAB/SIMULINK programming and the consequences of the Buck converter and the hybridized converter are introduced.
