Methane digesters. Exterior of methane digesters at a dairy farm. Animal manure is placed inside these structures where it decomposes and gives off methane gas which can be collected and used as fuel. This process of anaerobic digestion is widely used as a renewable energy source as it helps to replace fossil fuels. Photographed on a dairy farm in Elsie, Michigan, USA.
