In this paper consider the 100 lpd solar water heater available at Chennai, Tamilnadu. LCA has done as a three life cycle stages like manufacturing stage, operation and maintenance stages and product disposal stage. Based on the available data and calculated data life cycle inventory has been made for the solar water heater system. Material inventory, energy inventory and carbon inventory has done for the system to predict the environmental impact. Based on the life cycle inventory data Energy and Carbon intensity has been estimated for the solar flat plate collector. Then compared with electric water heater Energy and Carbon Payback Period has been estimated.

This is due to fuel combusted for their construction and as back up energy during their operation. Accurate calculation of greenhouse gas emission per kilowatt hour of electricity is difficult but is an important part of policy making and planning. This study, an attempt has been made to analyze and review the development and potential of wind and solar energy in India. LCA has been carried out for the on shore wind turbine and poly crystalline PV module. Based on the past studies, life cycle inventory data has been collected for the investigation. Using that data, the detailed investigation has been made for the existing grid connected 1.65 MW wind turbine project in and around Udumalpet, Tamil Nadu and 25 kW Roof top solar PV Power plant at Sewa Bhawan, New Delhi. Carbon intensity, energy pay back period and carbon pay back period for the above system have been calculated and compared with each other.

This inevitable situation leads us and increased the searching interest of bio based fuel. The present work illustrates that the synthesis of Bio-Ethanol from waste papers in particular, newspapers and magazine papers since it contains 40-55%, 25-30% of cellulose contents respectively. Several experiments were carried out to describe the Bio-Ethanol synthesis from waste papers by conducting series of chemical and biochemical reactions including acid pre-treatment, Delignification, Distillation and Fermentation. This work also summarizes the systematic study of Bio-Ethanol synthesis by fermentation process and the purity comparison of resultant obtained from various lignocellulosic sources. The Bio-ethanol obtained from the various waste papers was analyzed by Gas Chromatography (GC). The by-product i.e., solid residue obtained from the fermentation tank is used as a Solid Fuel. This study confirms that the production of bio ethanol was effective by using Saccharomyces cerevisiae in the pretreated waste paper. Keywords: Bio ethanol, Fermentation, Lignocellulose.

Renewable energy technology is one of the alternative to reduce the carbon emission and global warming potential. In the renewable energy, wind and solar cell power are the best methods to produce the power. But the efficiency of the systems are fairly low compared to the conventional method. This paper presents the most important factors that affect the power output of the wind and solar cell system. The efficiency of the system mostly depends on the climate condition of the particular location. This paper discusses about the effect of temperature and irradiation on the solar cell power output. Also a mathematical model is developed to study the parameters that affect the electrical power generated by the wind turbines. The considered parameters are turbine swept area, air density and wind speed. They are tested for the V1.65MW and V1.8MW wind turbines and also for the 124W and 170W solar panel. In this paper, the location has been taken as Gandhigram Rural University, Dindigul, Tamil nadu, India. KEYWORD: Wind Turbine, Solar cell, Wind speed, Air density, Irradiation, Temperature.

There is an increasing trend in the carbon emission in the world. Solar energy is one form of renewable energy emitting low carbon in the life cycle. The efficiency of the system is directly related to the carbon emission of the system in the life cycle. There are two parameter mainly affect the efficiency of the solar system that is solar radiation and temperature. This study presents a generalized photovoltaic (PV) system simulation model for Matlab/Simulink simulation environment. The proposed model is based on a behavioral cell model for modeling solar radiance to electricity conversion and to verify the various factors affecting the solar PV system efficiency. The Simulink model has been verified based the manufacture data of the 170W solar PV panel. The radiation and temperature data has been taken from the location of New Delhi.
