Wind Power Difficulties
Two difficulties with wind power have yet to be solved. First, there's the storage problem. The wind blows intermittently, even in the best of locations. But base energy is needed constantly and consistently. If wind is to become a truly viable power supplier, a low-cost, large-scale method will have to be devised to store that energy for use as needed by the grid.
Second, the U.S. national electrical grid is not extensive in areas that provide the strongest, most consistent wind conditions. To take advantage of wind power, the grid will have to be expanded and extended into these regions with many miles of costly, intrusive high voltage transmission lines.
