To ask Her Majesty's Government what impact the output and availability performance of onshore and offshore wind farms during November and December 2010 has had on their policy for non-carbon-producing energy generation.
None. Based on data available at this point, wind output was above average in November and below average in December 2010-both within the range of DECC's expectations. Wind is a variable resource of energy, with variations in output, both up and down, experienced from month to month as well as over shorter periods. DECC's analysis of supply capacity and projections of the growth of wind energy take into account the need for, and cost of, back-up capacity. Wind energy is an important and cost-effective low carbon energy source for the UK.
