If Europe is to achieve its carbon reduction commitments, a third of Europe's electricity will need to come from renewables by 2020, with wind power accounting for as much as 20% of the total supply. By 2030, wind power alone could provide a third of Europe's electricity – and half by 2050.

On paper, it looks straightforward to develop a new transmission system that can accomodate new renewable energy resources. Yet no one is pretending that it's anything other than a mammoth and highly complex task to put Europe's future on the right lines.
