In evolving countries like India, there is a swift growth in load and energy demand due to heavy industrial development, urbanization and economy rise. Most of this demand is met through power generation from conventional sources which have adverse environmental impact. Renewable energy resources provide a good alternative but lack of continuous generation, high initial cost, complex control, conversion between AC and DC generation, grid integration etc. are some of the drawbacks associated with renewable energy sources. To overcome these disadvantages and to efficiently utilize the available energy resources, a hybrid power system combining the advantages of individual power sources, can be seen as a preferred option to generate and deliver power. In this paper, an attempt has been made to perform techno-economic analysis of a hybrid power system existing in an educational facility with conventional grid power supply, diesel generator and photovoltaic generation and the results are summarized. An augmentation for the existing system has been proposed with biogas and small hydropower generation systems as these resources are available within the accessible limits of the study area.

A bioenergetic installation with a solar heating system for individual use designed for the processing and disposal of agricultural waste of organic origin with the production of biogas and liquid high-quality organic fertilizers under conditions of anaerobic fermentation was developed and built.
Its structural scheme and the principle of operation of individual parts of this installation are presented. Particular attention has been paid to the use of solar and accumulated solar energy for heating the substrate in the reactor.
The article presents the results of studies on the release of biogas from cattle manure and manure at various temperatures of anaerobic digestion. The data presented are the basis for choosing the optimal fermentation temperature in a small-scale biogas plant, as applied to small individual farms.
The robot shows the main parameters of the proposed biogas plant. In view of the application of this technology in a small biogas plant, it is most rational in terms of the ratio of the cost of heat to energy and output biogas.

Biogas is a kind of bio-fuel that occurs naturally as a result of the decomposition of organic
waste. When organic matter, including food waste and animal waste, decomposes in an anaerobic
(oxygen-free) environment, it releases a gas mixture, mainly methane (50-80%) and carbon dioxide
(20-50%).This document describes the combustion behavior of home-made Porous Radiant Burner
(PRB) used in industrial crematoryas well as bio-medical solid waste dumped systems. PRB is mainly
designed to work in the range of 5-10 kW firing rate, which is a two sided -layer porous environment
technique. Three kinds of burners namely convergent (60mm), straight (70mm), and divergent (80mm)
are considered for experiment. The burner contains two zones (i) combustion zone, and (ii) pre-heating
zone. Sic foam of 10 ppi with 25mm stiffness and steel balls (6.5 mm each) acts as combustion zone
and pre-heating zone respectively.From experiments, better efficiency is attained using the newly
designed PRB.This is performed by varying the equivalence ratio (ϕ) between 0.10 and 0.60 in a
constant operating range.The 59.92% burner operating range is the maximum efficiency analyzed for
a PRB with a diameter of 80 mm and a 0.16 equivalent ratio of 0.55 kW.
