Sankey diagrams

These diagrams are a way of looking at the input and output of energy for a power station or indeed any type of machine. They show the input energy and then the percentages of this that are useful output energy and 'wasted' heat energy.

The example is of a typical nuclear fission power station where only 42% of the input energy is finally converted to electrical energy.
