I take it as heavy lobbying towards a government narrowly re-elected just a week ago, and a sign that should this government fall at last in 4 or even 8 years (not to speak of 1-2, should this government fall apart), 50% by 2025 will almost certainly be achieved.

BTW, you can check up-to-date Danish wind power installation, decommissioning and production data (Excel!), and  monthly data for the whole electricity sector (Excel!). In the first link, you can see the 2001 drop, 2002 re-powering jump, and the slump since. From the second link, one can calculate wind's share in the brutto (with grid losses) electricity consumption:

(Note: last few years' variation is mostly due to weather, this year looks to end a series of bad wind years.) You see that 30% by 2025 is not at all ambitious.
