Well it’s not much but it’s something. There were apparently obstacles to the UK building more wind farms in order to increase their chances to meet the EU targets of 15% energy supplied from renewable sources by 2020.
The first obstacle was that it was believed the grid could not cope with the irregular nature of the supply from the turbines thus having to invest in coal-powered plants as a backup. That’s now been disproved. Secondly, building wind farms offshore* was believed to be costly and inefficient. That has also been disproved, though there is no link to statements or studies so you’ll just have to take the BBC’s word for it.
There are still some obstacles however, the fact that wind turbines have to be imported brings their cost up due to a poor pound as an example.
