Abstract: Wind energy continues to be one among the fastest‐ growing power generation sectors. In this paper, a small wind turbine was designed innovatively having different structure than the current windmill structure. The blade is an important part of a turbine and has a crucial role in the working of windmill. The objective of this windmill is to utilize the natural resource in a sustainable manner and design a windmill such that its blades will expand and contract based on the action of centrifugal force. If a windmill is designed and constructed in such a way that it can harvest more power over its life period, then it is a sustainable solution to our energy demand.
