Notes
a This is the figure against which we calculate the percentage of Scottish demand met by renewables.
b Total consumed figure is calculated on total generated less own use (in 2006 this was 4,597 GWh), transfers and losses (2,397 GWh)
c Gross consumption is total consumed including own use and losses (or generation less transfers ).
