Which character was a strong advocate for the windmill's construction?

Snowball is the character who was a strong advocate for the windmill's construction because he believed it would dramatically improve the farm's productivity and the quality of life for all the animals. He envisioned the windmill as a means to generate electricity and reduce the burden of labor on the animals, allowing them more leisure time and a better standard of living. His enthusiasm for the project was evident as he passionately outlined its benefits and even drew plans for the windmill, demonstrating his visionary leadership. Snowball's commitment to the windmill represented his broader ideals of innovation and progress, contrasting with the more pragmatic and authoritarian approach taken by other characters on the farm, particularly Napoleon, who later appropriated the project for his own purposes.
