⇒ The reason for energy transformation diagrams (also known as Sankey diagrams) is to quickly see how much of the input energy is being used usefully

⇒ Thicker arrows means more energy is being used. Where there are multiple arrows, that means that one source of input energy is getting transferred to various output energies

⇒ Each arrow, therefore, is proportional to the energy used
