the possibility of harbouring oil and gas deposits. The highest concentration of natural gas is found in the Mumbai High and Bassein Oil Fields. Gujarat, Assam, Tamil Nadu, Tripura, Rajasthan, Arunachal Pradesh, Punjab, West Bengal are the other areas, where natural gas reserves have been discovered. Compressed Natural Gas (CNG) (methane stored at high pressure) is a fuel which can be used in place of gasoline, diesel fuel and propane/LPG.

In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released. Biomethane – cleaned-up biogas from anaerobic digestion or landfills – can be used. Natural gas-run vehicles are increasingly used in Delhi, Ahmedabad, Mumbai, Pune, Kolkata Lucknow, Kanpur, Varanasi, etc. d) Thermal power Thermal power is generated using fossil fuels like coal, diesel, petroleum and natural gas.
