Wind power development in Britain enjoyed a record year in 2004 and expansion out to 2010 should result in some £7 billion of new investment in the sector, says the British Wind Energy Association (BWEA). Eleven wind projects totalling 253 MW came online by mid-December, with one more expected before the end of the year -- representing almost three times last year's build. Under construction are a further 18 projects totalling 600 MW, due for completion in 2005. The BWEA adds that 33 new projects totalling 800 MW were permitted in 2004 -- an 83% approval rate for the year. A further 94 onshore projects are going through the planning system representing 4767 MW of capacity -- equal to 5% of the nation's electricity needs. Looking ahead, a survey of BWEA members predicts that by 2010 some 7500 MW of wind will be installed in the UK, half onshore and half offshore. This will meet around 75% of the country's renewable energy target of a 10% share of UK electricity.
