what plan does snowball develop for improving life on the farm? how does that plan create controversy at first?

Snowball's biggest idea was to build a windmill which will provide electricity for the heretofore-primitive farm. Snowball estimates that the animals can complete the windmill with a year of hard labor, after which the time saving machine will shorten their workweek to three days. Napoleon counters with the idea that they will all starve to death in that time, and that the farm’s primary concern should be increasing food production.
