Windlicht, the latest work by Daan Roosegaarde and his team of designers and engineers, explores the unique connection between the Dutch landscape and green energy. In a country known for its progressive attitude towards sustainability, the idea of green energy has been around for thousands of years. Yet the concept and the Dutch landscape are changing. To draw attention to these changes, Roosegaarde and his team wished to demonstrate the “beauty of green energy.” In the darkness, green blades of light dance across windmill blades in St. Annaland, Zeeland. Unique software and tracking technology can detect the windmill blades moving at a brisk 280 km/hr.
