DECC produces data for all onshore wind generation, and total energy supply, on a quarterly basis. The following table shows the contribution of onshore wind generation to total UK energy, as well as electricity, supply in each of the last four quarters.
|Year/ Quarter ||Onshore wind generation (GWh) ||Proportion of UK total energy supply (percentage) ||Proportion of UK electricity supply (percentage) |
|2010 Q3 ||1,903 ||0.4 ||2.2 |
|2010 Q4 ||2,272 ||0.3 ||2.2 |
|2011 Q1 ||2,322 ||0.3 ||2.2 |
|2011 Q2 ||2,480 ||0.5 ||2.9 |
