Norwegian offshore wind power—Spatial planning using multi‐criteria decision analysis

Wind Energy
The Norwegian government recently agreed on the goal 30by40, which involves opening Norwegian offshore areas to host 30 GW of installed wind power by 2040. We address this goal by presenting a first mapping of wind power suitability scores (WPSS) for the
