This paper represent and assessment on solar power resource available in India. Day by day electrical energy consumption is increasing which also increases the generation of greenhouse gases due to uses of fossil fuel. The pollution level is crossing the danger limit, so world is moving towards practices of renewable energy sources. Solar energy is one of the largest and easily available renewable energy sources. Through this paper an attempt has been taken to discuss the solar resource available in India and the potentials related to solar energy has to be discovered. One detail case study on solar power uses has been given, the problem related to solar power application has been highlighted and finally the future aspect in India on solar power has been mentioned. India collects good annual solar emission although having several climatic zones. With this background India began its study towards renewable energy over three decades ago.

The gradual depletion of the fossil fuels along with their adverse implications on the global environment is a matter of increasing concern. To add to this further, the future progress and development of any country is judged by its capacity to harness the renewable sources of energy like wind, solar and geothermal energy. Of the various forms of renewable energies available, wind energy happens to be the cleanest. Though India is still primarily dependent on coal and petroleum as major sources of energy, it has become one of the major players in the production of wind power energy mainly due to the tremendous support from the Government of India and also of the huge coastal stretch. Currently it ranks third in the world in the production of wind power energy with wind energy accounting for 70% of the total energy supplied by nonconventional energy sources. This is more so important as energy demand is likely to increase by three times between 2005 to 2030. Keeping in mind that much remains to be done before its full potential is to be attained, the current paper attempts to present a brief review of the wind energy potential of India, its challenges, and possible suggestions to improve its present capacity.

This paper presents an optimal load flow model in conventional thermal power system to minimize the generation cost, active power losses and reactive power losses by introducing an additional wind generator in the existing system The electrical power demand of the growing concerns totally depends upon the conventional power plants. To satisfy the need of future demand, in view of the non conventional energy perspective as well as to preserve the conventional asset for future we introduce a wind power generator in the system and study the reliability as well as the voltage profile of the proposed system. Employing an approach of simulation at test loading of conventional system, we propose a system to decrease the total loss by using hybrid thermal-wind power system. The Voltage profile of the proposed system has also been tested. It has also been shown that the implementation of the proposed methodology can offer a net saving of generation cost. The proposed algorithm has been tested on standard IEEE 30 bus test system and the results obtained, looked promising.

The objective of this paper is to investigate the effect of temperature on anaerobic digestion of different lignocellulosic biomasses such as bamboo dust and saw dust. Bamboo dust and saw dust were mixed with cattle dung in 1:3 ratio in batch type anaerobic digesters of volume 1000 ml at 35°C, 45°C and 55°C temperatures. At five day interval, 10 ml of digested slurry was taken out from the digesters and tested for total solid and volatile solid contents. Effect of temperature on kinetic rate constant was also studied. It was observed that biogas production increases with temperature. The kinetic rate constant plays a significant role to indicate the digestion process.

This paper narrates an application of renewable source of energy in the area of generating electricity which is pollution free with the help of solar power and building newer models of integrated photovoltaic. As the world is facing critical problem of energy deficit, global warming and detoriation of environment and energy sources, renewable energy sources are getting more attention. Solar energy is one of the comparable candidates. Solar energy is widely available and it is free of cost. Solar energy can be converted into direct current electricity by PV effect. We are also trying on the practical usage of static electricity. In this paper, we study about the utilization of solar energy and building solar wall system. A significant amount of research and development work on the photovoltaic/thermal (PVT) technology has been carried out in developed nations, but that was not the case in India. Building integrated photovoltaic system (BIPV) can be considered as economical system by taking advantage of PV technology and providing benefits in addition to energy production like weatherproofing, insulation, and even structural strength to the building. Ventilation system with power generation is not been developed in India. A range of theoretical models have been introduced and their appropriateness validated by simulation as well as suitable experiments. The model the solar wall system is simulated in MATLAB.

To explore wind energy in high altitude Himalayan region a small wind turbine of 10 kW capacity is installed at the altitude of 2900 m at Banihal top (Jammu and Kashmir, India). Wind data from 1997 to 2007 are analysed to evaluate the capacity of wind power at the site. The design wind speed 14 m/sec is found with 2.5 Weibull k-factor. The hump of the ridge line is considered for installation of wind turbine. Computational fluid dynamics (CFD) analysis of the wind profile is carried out for the DEM of the area to obtain optimum height 8m of wind turbine tower. The standard IEC 61400-2 is adopted for designing S-special class small wind turbine for average rated wind speed 14 m/s. The wind turbine blade is selected after considering its fatigue and permissible bending stress at extreme wind speed of 35 m/sec at the site during 1997-2007. CFD analysis at different wind speed and angle of attack is carried out on the selected blade airfoil NACA 23015 for their optimum value. Lift and drag force coefficients are analyzed at various velocity and angle of attack with the help of ANSYS Fluent software. The cut-in speed of wind is decreased from 3.5m/s to 3.0 m/s by changing the angle of attack from 14° to 16° and by increasing effective swept area with special attachment to the hub. It helped to increase the efficiency and performance of wind turbine at low wind velocity without changing the blade profile and its length.

In this paper we discuss operational experiences of two large industrial anaerobic digestion facilities processing brewery waste and maize. The raw effluent from the brewery waste has COD ranging from 5500 mg/l to 41400 mg/l, with variable flow rate and suspended solids up to 4800 mg/l. The Anaerobic Digestion (AD) treatment uses 900m3 EGSB reactor. The two-year monitoring of data includes Ripley's Ratio, Volatile Fatty Acids, and pH. These parameters indicate lower performance and certain instability before the planned maintenance works, followed by the much improved performance afterwards. The average biogas production is 3540 Nm3/day but the variance of the biogas flow remains an issue. The combined Heat and Power (CHP) production from energy crops uses ensilaged, purposely grown maize with 28-34% dry matter and chop length of 6-9 mm. The available three-year data for this AD facilities indicate great process stability. It uses 150 t/day of maize, and result in energy production of 21 GW/year which is 7000 homes equivalent. This energy is evenly split between the sewage treatment works and injection to the public electricity grid. Depending on the dry solids content, the digestate is either stored and spread on the land, or sold to farmers.

Estimation of wind power extraction from kites flying at high altitudes is discussed in this paper. Estimation of power generated from high flying kites using the power prediction models by Lloyd (1980) and Pauli Rautakorpi et al. (2013) is made and results were compared using same kite motion parameters such as area of kite, density of air, height of kites etc. Using the kite motion data given by Pauli Rautakorpi et al. calculations were performed for prediction of wind power generated for the mathematical model of Lloyd (1980) for the lift mode of kite motion prescribed. Calculations were made for the kite height up to 5000 m (5 km) for maximum power and power extracted from wind, for both the models. Results obtained for maximum power were compared.
