Indirect source of solar energy conversion-sustainable biomass and biogas

In our industrialized society, it is quite difficult to maintain adequate supply of energy. As we all already know, fossil fuels are declining year by year, there is dire need to search alternative source of renewable energy. Various factors like rising population and shortage of commercial fuels in rural and traditional sectors have sustained the growing use of biomass as energy. One of most common alternative source of energy is Biomass. There are several source of converting biomass into biogas and many useful products. An attempt has been made to study on various sources such as water hyacinth, algae, grass, trees etc. The study emphasis on methods to generate biogas for cooking and lighting. Biomass plays an important role to act as renewable energy and assume to be best substitute for use of fossil fuels. Biomass proves to be solving many environmental issues especially global warming, reducing green house gas emission and sustainable development among poor nations. The study reveals the various types of biogas unit used in India such as floating and fixed dome type biogas plant and compares it with other biogas unit available in the market. No doubt, energy from biomass is more reliable as it is free from fluctuation like wind energy.
