I grew up on a farm outside of Plains, Georgia. It was the Great Depression years; we didn't have electricity or running water. The first appliance we had was a windmill, for piping water into our house.
In fact, we didn't have any gasoline or diesel motors for a number of decades; mules and horses did all the work. We got all our energy from growing corn—the animals that we worked, the animals that we ate, and all the human beings depended on corn as just about our only fuel. We were totally renewable back then.
