Explanation:

Transport sector is the biggest consumer of energy, especially railway as the single largest consumer with share of about 2% of National energy consumption. Rail being the most energy efficient mode of transport is further working to change the energy mix towards greener sources. Electrification is a powerful measure to achieve cost effectiveness. It improves mobility by use of high power energy efficient Locomotives, facilitate shift of traffic from road to rail and also to reduce carbon footprints. In addition, electrification will also reduce traction energy bill substantially. With its rising energy needs, India has emerged the fourth largest energy consumer of the world after the US, China and Russia, but its per capita energy consumption remains lower than that of developed countries
