Wind turbines at 90 per cent efficiency LESS than 20 hours a year
WIND farms fall hopelessly short of achieving their full electricity generating capability, a study has found.
Experts discovered that turbines break the 90 per cent efficiency mark for only 17 hours a year.
Data showed wind farms generate below 20 per cent of supposed output for 20 weeks a year and less than 10 per cent for nine weeks.
The statistics are in a report by the respected Adam Smith Institute think tank and Scientific Alliance.
The findings follow news that a Lords committee was told relying on wind power would lead to a doubling of energy bills and power cuts by 2030.
