Wind energy is great, but it’s inconsistent. When the wind stops blowing, your power stops flowing. New power systems are needed to capture excess energy when the wind is blowing its hardest so that it can release that energy when it’s blowing little or not at all. It turns our that Duke Power Corp. has taken up the challenge. It plans to build the largest power storage system (to be linked to a wind farm) in the world. The system will be located in West Texas. It’s nice to see a US company leading in this market.
