Offshore proving much more capable then onshore

The European Wind Energy Association (EWEA) estimates that current turbines are capable of achieving 24% capacity factor onshore, and 41% offshore. (The capacity factor is defined as
actual power generation capability divided by nameplate capacity, in percentage terms). EWEA estimates that a growing offshore base will enable an average capacity factor of 33% by 2030 which will make offshore one of the most efficient sources of renewable energy.
