since the last decade. The commercial energy/power consumption in India is distributed among agriculture, industry, transport, domestic, and other sectors. Ast can be easily inferred, all the energy demands of India cannot be met by coal alone, as the agriculture sector alternatively uses coal-powered electricity as well as oil, the transport sector is totally dependent on availability of petrol and diesel, and also fuel switching in some of the power plants from coal to oil/natural gas has taken place. In order to meet the growing demand for oil, India imports about 70% of the total crude oil requirements. Other than consumption of fossil fuel energy, about 90% of the rural and 30% of urban households in India consume a large quantity of traditional fuels or non-commercial energy such as firewood, dung cake, chips, etc. The total renewable energy consumption in India, including biomass energy, amounts to about 30% of the total energy consumption, the rest being fossil fuel consumption. As a large part of the energy is still derived from fossil fuel, energy security is a matter of concern for India, although in the future it is expected that alternate sources of energy like biofuels would also be available. However, as mentioned earlier, coal being abundant, cheap, and locally available, it will be the mainstay of energy in the country for many years to come.
