Explanation:
Snowball wants to build a windmill in George Orwell’s novel as a symbol of progress and self-sufficiency for the animals. He believes that harnessing wind power to generate electricity will not only improve the farm’s efficiency and make life easier for all the animals but also help them break free from their reliance on the oppressive human owners. The windmill represents his vision of a better future, where the animals can control their destiny and create a more equitable society, aligning with his ideology of Animalism and the principles of the Rebellion.
