Well to get 6 terawatt hours in a month, assuming running 24hours a day for 30 days @ 100% output is approx 8.33GW generation capacity of wind. Based on efficiency of wind turbines realistically that would be closer to 3x so I am guessing about generation capacity of 25GW (25,000MW)
Now assuming the 8.33GW for each turbine is about 5MW = 1666.666 wind turbines install.
conclusion the DEVIL IS IN SPAIN.
wind will never replace gneration completely as is relies on wind. Once the wind stops or blows too hard the turbines stop to, menaing need spinning reserve on fossile fuel in the event that happens.
