Four-bladed wind turbine with cylindrical nacelle

A three-bladed wind turbine, primarily green, is depicted. The tower is a tall cylinder with a slightly tapered, pointed top. Attached to the nacelle, a rounded ovoid element near the top, are three blades radiating outwards. These blades exhibit a subtle curve along their edges and connect to the nacelle via a central circular hub. The turbine's design suggests its function is to convert wind energy into rotational motion.
