So turbines grew. And they can now span up to three hundred feet at the hub height, but they can't really go a lot higher, and more height is where the more wind is, and more power -- as much as twice as much.
No turbine su rasle. I sada dosežu do 90 metara visine pri glavčini, ali ne mogu ići mnogo više, a na većim visinama ima više vjetra, i više snage -- čak i do dvostruko više.
