The contribution of natural gas in total electricity generation is estimated to decrease from 60% in 2000 to about 43% in 2050 but remains the mainstay of electricity generation. In contrast, the corresponding figure for coal increases steadily from 21% in 2000 to about 42% in 2050.The increasing share of coal over natural gas in total electricity generation is mainly due to relatively cheaper price of coal as compared to price of natural gas and the limitation of domestic natural gas resource availability in the country. The share of oil, already low (10% in 2000), is estimated to decline further during 2000–2050. Among the share of NRE sources in total electricity generation in year 2000, hydro and new renewables together accounted for about 10% and there was no biomass-based electricity generation in the country. However, the share of NRE sources in total electricity generation would increase to 15% in 2050 and this share comprises of biomass (8%),hydro (4%) and new renewables (3%).
