Renewable Energy Sources Latest trends in research and development of renewable energy sources.

I have found a great web page where you can calculate annual wind turbine energy output:

I will not go in to details about the correctness of the method used there. But I guess this could be of help to receive some rough estimates on the energy output. In practice big differences can occur, depending on the brand and type of the chosen wind turbine.

Hope this helps.
