摘要：The Energy Flow Chart published on 31 July 2008, see figure 2 on page 57, illustrates the 2007
flows of primary fuels from home production and imports to their eventual final uses. The flows are
shown in their original state and after being converted into different kinds of energy by the
secondary fuel producers. The flows are measured in million tonnes of oil equivalent, with the
widths of the bands approximately proportional to the size of the flow they represent.
