Until Napoleon chases him off the farm with his dogs, Snowball is an innovator, always coming up with new ideas to make the life of the animals better. In addition to building a windmill, he would like to extend education to all animals. He wrote the first version of the Seven Commandments, and he thinks its important to foment revolution on neighboring farms to keep the spirit of revolution alive. All of these things are remindful of the role Trotsky played in the Russian revolution,.
Snowball thinks that a windmill should be built. He promises that the windmill would give the animals a three day work week, and better living conditions. The electricity would provide comfort to the animals, such as heated stalls.
Snowball says that by putting in the hard work now would provide a better future for them.
Napoleon argues with him about it and wants to focus on other concerns. His argument is that they should focus on the present, and worry about the future later.
