The 2010 statistics for offshore wind came out this week, and they look pretty good:
With 308 new offshore wind turbines installed in 2010 - an increase of 51% in installed wind power capacity on the previous year - offshore wind power experienced a new record growth in Europe. In total, 883 Megawatt (MW) of new capacity, worth some €2.6 billion, were installed in 2010 in nine wind farms in five countries, making a total of 2,964 MW.
(...) 2010 saw an improving financing environment with private banks, financial institutions like the European Investment Bank (EIB), utilities and pension funds backing the sector. Two major deals completed in 2010 highlighted the brighter financial outlook: Thornton Bank C-Power and Trianel Wind Farm Borkum West both came to financial close.
