The material from which the fan blades are made is also another important factor because a heavier material would add weight and would require a more powerful fan motor. Parwaz in 2001 compared the airflow generation and energy consumption of nine ceiling fans fitted with metal, wood, and plastic fan blades. They found that ceiling fans with wooden fan blades generated the least airflow and yet consumed among the highest amount of energy. But due to the lower airflow, wooden fan blades were quieter than the rest. Schmidt and Patterson further found that ceiling fans with metal blades generated the most airflow but were also among the noisiest.
