The anti-wind-power John Muir Trust releases a report finding several shortcomings to Scottish wind farms, including that the turbines turned less and delivered less power than had been advertised.

1. 'Wind turbines will generate on average 30% of their rated capacity over a year' In fact, the average output from wind was 27.18% of metered capacity in 2009, 21.14% in 2010, and 24.08% between November 2008 and December 2010 inclusive.

Stuart Young, author of the report, said, “Over the two-year period studied in this report, the metered windfarms in the U.K. consistently generated far less energy than wind proponents claim is typical. The intermittent nature of wind also gives rise to low wind coinciding with high energy demand. Sadly, wind power is not what it's cracked up to be and cannot contribute greatly to energy security in the UK."
