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.
