Detailed explanation-1: -Large parts of the Netherlands lie below sea level. Water needs to be constantly pumped from the low lying areas (polders) in order to keep them dry. Before steam and electricity, wind energy was the only source powerful and reliable enough to do this on the scale that was needed.

Detailed explanation-2: -Historically, windmills in Holland served many purposes. The most important probably was pumping water out of the lowlands and back into the rivers beyond the dikes so that the land could be farmed. In the fourteenth century, hollow-post mills were used to drive scoop wheels to drain the wetlands.

Detailed explanation-3: -People have been using wind energy for thousands of years People used wind energy to propel boats along the Nile River as early as 5, 000 BC. By 200 BC, simple wind-powered water pumps were used in China, and windmills with woven-reed blades were grinding grain in Persia and the Middle East.
