Carbon dioxide from the burning of fossil fuels remains in the atmosphere and is not absorbed by vegetation and the oceans. While transparent to visible light, carbon dioxide is a greenhouse gas, absorbing and emitting infrared radiation at its two infrared-active vibrational frequencies (see the section "Structure and bonding" above). Light emission from the earth's surface is most intense in the infrared region between 200 and 2500 cm, as opposed to light emission from the much hotter sun which is most intense in the visible region. Absorption of infrared light at the vibrational frequencies of atmospheric carbon dioxide traps energy near the
Electricity sector in India 100 MMSCMD. The break even price for switching from imported coal to LNG in electricity generation is estimated near 6 US$/mmBtu. Indian government has taken steps to enhance the generation from the stranded gas based power plants for meeting peak load demand by waiving applicable import duties and taxes due to drastic fall in the LNG and crude oil international prices. Gasification of coal or lignite or pet coke or biomass, produces syngas or coal gas or wood gas which is a mixture of hydrogen, carbon monoxide and carbon dioxide gases. Coal gas can be converted into synthetic natural gas
