I found this link list very helpful from Jerome a Paris. This is a complete list of ET diaries and stories related to wind power.
An excellent link to the storage of wind energy by using the energy to compress gas and store this gas in large underground structures (Compressed Air Energy Storage, which was first used in 1978). Venting the compressed gas through turbines then recovers the energy at a later time. Here is the story.
Wired highlighted this technology also. Here is the article. The comment section is hilarious.
