The larger your energy network, the better you can deal with the fundamental problems of cyclical power like solar and intermittent sources like wind, by pooling availableenergy and getting it to the users when needed.
The amount of energyavailable in the Earth system to be extracted by wind turbines is limited, and if sufficient energy is removed the world climate will be affected.
The bigger problem: Despite being the cleanest energyavailable, some environmental groups object to large wind turbines spoiling the landscape, as well as the impact on migrating birds.
