Consumers face bill for power stations to be mothballed amid blackout fears - Telegraph

There's an odd line in this Telegraph report http://www.telegraph.co.uk/earth/energy/10325749/Consumers-face-bill-for-power-stations-to-be-mothballed-amid-blackout-fears.html

'Critics of wind power said turbines were flawed because they do not generate electricity when there is little wind,' 

Does that mean that supporters of wind power believe that wind turbines generate electricity when there's little wind?
