As the production costs with windpower decrease due to the technological progress, the question of grid storage and grid interconnection becomes more pressing.
E.g. in Germany, they frequently have days of negative energy prices, where producers need to pay to feed energy into the greed because of overproduction of energy on windy/sunny days [0](in German). Without storage and grid interconnection, there is only so much renewable energy from intermittent sources like wind and solar you can handle.
