  2. 2. INDIAN ENERGY SCENARIO• Coal Sector – 7.1 % of the world reserves – higher calorific value and low ash content coal are being imported mainly from Australia, Indonesia and South Africa – 15 % of the annual coal requirement imported – A tax (clean energy cess) of Rs. 50 on every tonne of coal mined in the country as well as that imported from abroad.• Oil Sector – 0.5% of the total world reserves – accounts for about 31 % of the country’s primary energy consumption – transport accounts for 42% followed by domestic sector and industry sector with 24% each respectively• Natural Gas Sector – 0.6% of the total World reserves – natural gas is cooled to -161oC to get Liquefied Natural Gas (LNG) (600 times reduction in volume) – Compressed Natural Gas (CNG) is made by compressing natural gas to less than 1% of the volume it occupies at standard atmospheric pressure – accounts for about 8.6 per cent of fuel consumption
  3. 3. • Out of the total annual primary commercial energy supply of 408.49 MTOE, 62.5% of total primary commercial energy is used in the form of Coal, oil, gas for non thermal power generation etc, whereas 37.5% of total primary commercial energy is used for thermal power generation .• Designated sectors (Cement, Iron & Steel, Paper & Pulp, fertilizer, aluminum, textile and chlor- alkali) except Thermal Power Plant account for (122.26 MTOE) 29.9% of total primary commercial energy consumption.
