The way that alternative energy sources work, like windmills, solar panels and hydro power is that they create electricity whenever they are running. These sources could supply electricity directly to a building while they are producing with out batteries, however to store the energy for later use (like when the wind is not blowing, sun is not out, or spring is dry) batteries are necessary. So it depends on the windmill, but generally most will have batteries in a modern setting.
