The results suggest that using 92% of all coal
and gas power plants would allow this algal biofuel source to replace petro diesel entirely and has the potential to sequester
approximately 13 to 14% of greenhouse gas emissions. The challenge at the present is to improve the efficiency of algal fuel
production technology so as to lower the cost of algal biodiesel and thereby make it commercially competitive with
petro diesel. Additional economic sensitivity studies were established to identify the future cost of algal biofuels. Researchers are currently developing various means of accomplishing this and successful commercialization is anticipated by 2023-24.

Different forms of renewable energies have been discussed along with the most important one, the solar energy. The solar module is the equipment to converts the sunlight into the electricity directly. The modeling of PV (photovoltaic) systems is very crucial for designing the system for practical applications. This book presents a PV array model developed using Matlab/Simulink where the effect of solar insolation and PV array temperature on commercial PV modules have been studied through the simulated P-I ,I-V and P-V output characteristics. The proposed model facilitates simulating and monitoring the dynamic performance of PV-based systems. Therefore, the accurate solar module model established in this book can be applied to the simulated photovoltaic generation system in order to precisely simulate and predict the characteristics of power generation for real photovoltaic system. In summary, this book is a valuable asset for every solar engineer. It provides an step-by-step information about the MATLAB Modelling of Solar PV Pane

In this paper, an attempt has been made for evaluating thermal, electrical and exergy output of solar PV panel installed at Energy Centre, NIT Bhopal. Using the first law of thermodynamics, energy analysis was performed and exergy analysis was carried out to determine exergy losses during the PV conversion process by applying the second law of thermodynamics. The operating and electrical parameters of a PV array include PV module temperature, overall heat loss coefficient, open-circuit voltage, short-circuit current, fill factor, etc. were experimentally determined for a typical hazy day of March (10 March 2012) at Bhopal. The experimental data are used for the calculation of the energy and exergy efficiencies of the PV systems. Energy efficiency is seen to vary between 6% and 9% during the day. In contrast, exergy efficiency is lower for electricity generation using the considered PV module, ranging from 8% to 10%. It is observed that the PV module temperature has a great effect on the exergy efficiency, and the exergy efficiency can be improved if the heat can be removed from the PV module surface. It was concluded that the exergy losses increased with increasing module temperature.
