When we think of the Holland, the image of quaint Dutch windmills readily pops up in mind. In fact, these iconic windmills are so popular that the Dutch village of Kinderdijk, housing 19 windmills, has recently been added to the list of UNESCO World Heritage Sites. So, we all know that these huge windmills featuring lattice-shaped blades were not powering up the neighborhood. But then, why were these wind farms used?
Infact, these windmills were used as a flood control system by the ancient Dutch in the 15th century. As one-fourth of the Holland is below the sea level, the country is prone to floods. As the climate change threatens the world, more countries are adopting the Dutch flood control mechanisms that are refined over the centuries to protect cities from the risk of flooding.
