"Having fewer total turbines means a wind farm could space them farther apart, avoiding airflow interference. The turbines would be nearly twice as tall, so they’ll reach a higher, gustier part of the atmosphere. And big turbines don’t need to spin as quickly, so they would make economic sense in places with average wind speeds around 5 meters per second… "
But do we really need bigger turbines? It seems the ones we have work fine.
