The Energy flow chart 2008[filetype:pdf filesize: 376.24Kb] illustrates the flow of primary fuels from home production and imports to their eventual final uses. DECC shows them 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 (mtoe), with the widths of the bands approximately proportional to the size of the flow they represent.
The next update, in summer 2010, will contain the 2009 UK energy flows.
According to Wikipedia 1 MWh = 0.086 toe, therefore 1 TWh = 0.086 mtoe.
So an annual year output of say a Cardiff-Weston Tidal Barrage at 17 TWh would be equivalent to 1.5 mtoe. This is above the same as the consumption of the UK's Iron and Steel industry but perhaps not all generated at the right time!
