What innovations in wind power farms can lead to significant improvement in the performance and significantly lower costs?

Wind power is one of the largest commercialized sources of renewable power. While there have been improvements in output and cost reductions, capacity utilization factor remains at about 25-30% for most onshore wind farms, and cost reductions appear to have plateaued as of 2018. What are the innovations and avenues that can significantly increase output and decrease the overall cost per unit of power generated from wind farms?
