1. production rose steadily from 120 MT in 1980 to \>700 MT in 2018 2. 2nd largest producer of coal in world after china

Answer 108

1. demand has been consistently rising with Industries in India consuming 968.25 MT of raw coal in 2018–19 2. largest consumers of coal in India are electricity generation (67%), the steel and washery industries (8%), the sponge iron industry and the cement industry. 3. Consumption of lignite stood at 45.81 MT in 2018–19. Electricity generation alone accounts for 82.23% of the total lignite consumption 4. Coal generated over 70% of electricity produced 5. On average, the Indian power plants using India's coal supply consume about 0.7 kg of coal to generate a kWh, whereas United States thermal power plants consume about 0.45 kg of coal per kWh. This is because of the difference in Gross Calorific Value (4500kcal/kg in india vs 6500 Kcal in Australia).
