The diagrams illustrates the process of energy lost in 100 units when it is generated from black coal and when it is generated from brown coal.
Overall, there are many stages in the process of energy lost in 100 units, which start with transfering fuel energy input around 100 units via truck to the power station and ends with remaining 27 units for consumer.
In terms of the brown coal, fuel energy around 100 units transfered to the power station by a truck. Then, loss 70 units in power station. Afterwards, 32 unit come to transportation & distribution and lost 3 units. Next, it remained for consumer at 27 units.
According to the black coal, fuel energy input around 100 units via truck to the power station, where it loss 68 units. Then, 32 units go to transportation & distribution and loss approximately 3 units. Finally, 29 units delivered for consumerto use it for their need.
