The diagrams illustrates the amount of energy lost in 100 units when it is generated from black coal and when it is generated from brown coal. Overall, the brown coal and the black process consists with 4 distinct steps.
First of all, fuel energy was input as 100 units for power station by lorry. After that, power station was burned 70 units. Then, remained 32 units were transmitted to the transportation and distribution. Following the stage, it was loose 3 units. Finally, consumer can taken 270 units from brown coal electricity generation.
Furthermore, the black coal electricity generation was similar for brown coal. Firstly, 100 units of fuel energy was dilivered by lorry for power station. Then, it was used 68 units in their process. After that, remained 32 units were transmitted to transportation and distribution stage. Following the step, it was loose 3 units, and distributed 29 units for consumer.
