The civilization known for developing windmills as a source of energy is primarily the Persians around the 7th century AD. Persian windmills, called "badgir" or windcatchers, utilized the wind's power to help with tasks such as grinding grain and pumping water. This innovative engineering adapted to the arid climate of Persia, demonstrating an effective means of harnessing renewable energy. Later, windmill technology spread through Europe, particularly in the Netherlands, where windmills were used for a variety of purposes including drainage and grain milling. The development and use of windmills significantly contributed to agricultural and industrial advancements in these regions.
