Growing energy needs and the depleting nature of the nonrenewable sources demand the intervention of renewable sources and storage technologies which are sustainable. It is therefore desirable to perform sustainability analysis in terms of energy efficiency for electrochemical storage systems. This paper is concerned with life cycle energy analysis of batteries used for photovoltaic application in Indian context. The analysis is based on real production and transportation data for India, making it first of its kind to be presented to the technical community. The material production energy contributes about 50–75% of the total energy requirement of the life cycle of the battery. Transportation Energy has a significant contribution for Lithium Ion battery. The significance of manufacturing and recycling energy is specific to the battery technology.

In this present work focused on combination of two different biodiesel blends with diesel. The present study brings out an experiment of two bio diesels from jatropha oil (B20J), Mahua oil (B20M) and Dual biodiesel(B10M+B10J) they are blended with diesel. The effects of dual biodiesel works in engine and exhaust emissions were examined in a single cylinder, direct injection, air cooled and high speed diesel engine at various engine loads with constant engine speed of 1500 rpm. Results showed that at full load conditions the brake thermal efficiency B20J is higher than other blends. BSFC lowest for diesel compare to other blends. The emissions of CO and HC of dual biodiesel are lower than that of diesel. But NOx is higher in dual biodiesel compare diesel.

Rise in energy demands and the need to curb carbon emissions has made proliferation of conventional fuels unviable, leading towards the search for alternative energy sources. With a surplus of sunlight reaching the earth every day, solar energy is an immediate renewable alternative to be considered for satisfying the end-user demand requirements. However, generation using solar energy poses its own challenges such as low energy density, fluctuations in energy generation, and mismatch in supply-demand, making it impracticable. In this paper, recent developments in solar thermal and solar photovoltaic systems utilizing thermal energy storage (TES) for heating applications have been reviewed and presented. A general trend in improvements in performance and efficiencies of the solar thermal systems were observed by integrating them with the TES modules. Furthermore, it is suggested that, research in terms of materials suitable for solar thermal storage and design of thermal storage systems is necessary in achieving cost efficient solar-TES systems with enhanced performance for a variety of heating applications.

Silver nanoparticles are often used as optical resonator or scatterer in different opto-electrical devices. But being a metal, high ohmic loss will occur because absorption and scattering both peaks arises at the same resonating frequency. To overcome this limitation, separation of absorption peak and scattering peak is very much needed. So in this work we present a method using metamaterial incorporating Poly Vinyl Pyrrolidone (PVP) capped silver nanoparticles which is able to decouple the absorption and scattering peak successfully with changing the thickness of the cladding layer. Study and analysis has been done to tune the resonance frequency shift between the absorption and scattering peak by varying cladding thickness. A shift of 116nm between resonating frequency of absorption and scattering efficiencies is observed for 50nm PVP cladding on core of 100nm diameter of silver nanoparticles.

In recent years, the majority of the research has focused on grid-tied transformerless PV inverters, more capable than traditional grid-tied line transformer-based PV inverters, but more critical from a power quality point of view, especially in terms of common mode voltage and ground leakage current. Neutral point clamped (NPC) converters have recently gained popularity due to high efficiency and inherently low ground leakage current. This paper presents the three level active NPC (3L-ANPC) topology for grid tied PV applications with a third harmonic injection PWM strategy that allows to increase the magnitude of sinusoidal modulating wave by 15.5 % which improves dc link utilization. Simulation is carried out in Matlab/Simulink environment which confirms the effectiveness of the proposed converter.

Govt. of India scaled up of budget during 12th five year plan for Rooftop solar project to achieve the target of 40 GWp as committed before UNFCC (United Nations Framework Convention on Climate Change). In this connection through a case study it is shown that there is a chance to reduce the target and also the space of solar project installation if a manual solar tracking based on optimum tilt angle as proposed in the study can be included in the policy for future small solar project initiatives. An equation set of monthly solar optimum tilt angle has been proposed based on an anisotropic validated model developed by FORTRAN 77 Compiler. The equation set is applicable for a wide latitude range of 13° to 39° of northern hemisphere i.e. it includes all over India. If the proposed optimum tilt based manual tracking has been adopted in Govt. policy of solar project then the target to UNFCC will be reduced to 36.5 kWp i.e. a decrease of 8.75% and the required area for solar installation will also be decreased of 8.84%.

The work is carried out in two ways; one is the overall exergy efficiency of glazed photovoltaic thermal (PVT) module which is optimized with soft computing technique. Evolutionary algorithm is used as a computing techniques in this work. The overall exergy efficiency is considered as the objective function while the optimization is carried out. Secondly, the annual performance of optimized (different parameter like the depth and length of the channel, thickness of tedlar etc.) glazed PVT module has been evaluated. This evaluation has been carried out in four different cities of India (New Delhi, Srinagar, Jodhpur and Bangalore). Here the four weather conditions have been considered like-sClear days, Hazy Days, Hazy and cloudy days and Cloudy days. Overall exergy efficiency for New Delhi, Bangalore, Srinagar and Jodhpur has been observed for a year, for each weather condition. There are improvements in overall annual exergy efficiency, annual thermal gain and annual exergy gain of the proposed glazed PVT module for New Delhi, Jodhpur, Srinagar and Bangalore and the range of improvement in monthly overall exergy efficiency is 5.8 % to 14.70 % than the model given in literature.

The increasing stress on the rapidly diminishing conventional sources of energy like coal and fossil fuels and the devastating ramifications posed by their use in energy production has compelled man to look for cleaner and voluminous alternative sources of energy. Among the various renewable sources of energy, wind happens to be the most abundant and omnipresent one. However, there are various implications that arise when it comes to designing of efficient wind generators and integrating these systems into the main grid. Enhancement of the overall efficiency is a major cause of concern due to certain unavoidable constraints in the mechanical design of these turbines. In this paper, a novel MPPT algorithm optimized by Newton Raphson technique based on hill climbing search (HCS) strategy has been implemented for a wind turbine cascaded with a permanent magnet synchronous generator subjected values of wind velocity. The eligibility of the proposed methodology has been highlighted through in depth analysis of the stability of the system for operation along the optimal power reference curve obtained by the algorithm.
