In your complete message only one sentence I can see is reduction in deisel Bill to IR. So Any how IR start paying unit rate of using Electricity which is produced by majorly conventional sources like coal Uranium, water so indirectly one source is being used to produce another one it's like just Transformation of energy with losses.. Anyway it's just good discussion we having on energy conservation for IR.. We need to know unit cost of usage of deisel and usage of Electricity and also need to know how much cost it takes to generate electricity and what sources being consumed..
