Abstract

Rural population of India depends on bio-energy for cooking, space and water heating. Though most of the energy needs in India is harvested from fossil fuels, 70% of the rural population depends on the bio-energy for their domestic usage in the country. About 70% of the Indian population lives in rural area where 75% of the primary energy need is supplied by bio-energy resources. Also, about 22% of the urban households depend on firewood, 22% on kerosene and 44% on LPG for cooking in India. Bio-energy resources are renewable in nature and combustion would not produce poisonous gases and ash with sufficient oxygen supply. A village level study on the present scenario of domestic energy consumption will help to assess the demand and supply of bio-energy in the country. India offers a conducive environment for accelerating the use and internalisation of bioenergy technologies (BETs). Nearly 25% of its primary energy comes from biomass resources, and close to 70% of rural population depend on biomass to meet their daily energy needs. Energy is the primary driver of the world’s economies. Increasing populations and expectations of improved standards of living are accelerating the demand for energy. Theorists have acknowledged the positive or direct relationship between economic growth and greenhouse gas (GHG) emissions. One of the key variables affecting this positive relationship is increased energy demand as a result of economic well-being. India is one of the fastest growing countries in the world, with a GDP growth exceeding 8% consistently for the last two years, and this trend is expected to continue. India’s energy demand is expected to be more than three to four times its current level in another 25 years (Planning Commission, 2005). Present primary energy use in India is dominated by fossil fuels: 40% of primary energy supply and 59% of power generation come from coal (IEA, 2007). The rising energy demand in India is expected to lead to a further increase in the use of fossil fuels. This will not only lead to growing GHG emissions and increased India is traditionally using biogas since long time but there is need to improve the technology, applications and deployment strategies. Bioenergy centralization in urban and decentralization in rural can help government to minimize both the import of fuel derivatives and solid waste processing cost. The aim is to highlight potential of the technology to bring social and economical sustainability to India. In this review, demand of energy sources, drivers for bioenergy use, economical, social and environmental benefits of biogas regularization in India are described with emphasizing biogas as an ideal sustainable energy source with its potential applications.
