The Energy Scenario in IndiaThe Energy Scenario in India
Of the fuel consumed for domestic use (cooking,Of the fuel consumed for domestic use (cooking,lighting, hot water) about 14% is accounted for bylighting, hot water) about 14% is accounted for by
commercial fuels such as gas, kerosene, coal, andcommercial fuels such as gas, kerosene, coal, andelectricity. The remaining 86% is nonelectricity. The remaining 86% is non--commercial andcommercial and
includes wood, biomass and cowdung.includes wood, biomass and cowdung.
Burning less cooking fuel implies less deforestation andsignificant national energy savings.
About 40% of Indias energy isconsumed in cooking. This
astonishing statistic isaccounted for by the size of
Indias population in relation toits level of industrial
development.
