Wind Power Calculator Energy vs Turbine Size vs Speed

In reality in most areas you will rarely get these speeds Note that the available energy of the moving air molecules is proportional to the cube of their velocity so even small decrease in the speed results in large decrease in the energy A turbine rated for example at 5000 watts at 30 mph will produce only 625 watts or less at 15 mph
