Yes. In recent years, onshore wind power has evolved into a mature technology that is profitable without government subsidies. When Alcoa enters into a long-term power purchasing agreement with Øyfjellet, it is precisely because wind power has become competitive in terms of price.
New wind power facilities use extremely advanced technology and can yield profits without renewable energy support schemes (green certificates) or other forms of support. This means there may now be grounds for taxing wind power plants so that host communities are guaranteed income from such installations.
