english: 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.
non_english: I turbine su rasle. Sada mogu imati do 90 metara u nivou osovine, ali zapravo ne mogu ići još u visinu, a na većim visinama je više vetra  i više energije - skoro duplo više.
