It's important to note that wind power in Denmark only works at that scale because they can export it to Norway and Sweden. Those neighbors can absorb variable power output while load balancing their grid with hydroelectric dams. Hydroelectric is currently the only economical "grid-scale battery", and it is not available everywhere. http://www.theoildrum.com/node/1735 http://www.theoildrum.com/node/1735
