How Windmills in the Netherlands Work

Basic Principle

Wind turns the blades, which rotate a shaft. Gears increase rotational speed, converting kinetic energy into mechanical energy for grinding grain, pumping water, or generating electricity.

Types

• Vertical‑axis: Blades vertical; suit urban spaces; work at lower wind speeds.
• Horizontal‑axis: Blades horizontal; more efficient, need more space; common in rural areas.

Dutch Context

First built in the 13th century for grain, later for drainage (16th century). Today, the Netherlands is a wind‑energy leader with advanced turbines and the world's largest offshore wind farm, targeting carbon‑emission reduction.
