Energy efficiency and energy conservation are priority areas of energy policy in most countries of the world. First of all, this is due to the exhaustion of non-renewable fuel and energy resources, the absence of real alternatives to their replacement, the presence of risks and significant costs in their production and transportation

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.

Heavy dependence of fossil fuels among people contributes to GHG emissions and air pollution. This survey assesses the awareness of renewable energy sources among the general population. Various factors and benefits of switching back to renewable energy sources includes reduction in atmospheric pollution and saving from monthly energy bills can be done if solar energy was used instead of electrical energy. With the advancement of smart technologies conversion of renewable energy from one source to another became easier, This study consists of structured questionnaires administered to participants through online google forms link. The data was collected and statistically analysed using SPSS software. The people were aware of the benefits of renewable energy, they needed to educate the society regarding the prevention of environment pollution by switching to renewable energy sources consumption. The association between groups was assessed by Chi Square test where p < 0.05 was considered statistically significant. This study concludes that there is awareness upto a certain extent among people on renewable energy sources. Even though not significant, the majority of the 15 to 20 years aged study population knows better about renewable energy than the other age groups. The awareness about the benefits of renewable energy is required for a better future.
