Wood vs PVC Wind Turbine Blade

The wind turbine blade has undergone many changes over the years. Improvements in blade design have made the wind turbine one of the most efficient devices in power generation. Metal, fiberglass, wood and PVC are some of the commonly used materials in construction of turbine blades. Of these, wood and PVC appear to be the top choices. Below are the pros and cons of each.

Pros of Wood Wind Turbine Blade

The natural appearance of wooden blades enhances overall landscape beauty. If enhancing a natural setting appeals to you, wooden blades are ideal. They also give you more flexibility where color change is desirable. The blades can easily be painted according to your color preferences. Wooden blades are cheap which makes it easier to install a wind turbine. This allows you to complete your project without being inhibited by cost of materials. The soft nature of wood gives you increased flexibility in design. It makes it easy to customize your blades according to your individual preferences. Design options are greater for wooden blades than PVC which is tougher. Wood is also light which makes it easier and more comfortable to work with.


More time is required to build wind turbines that have wooden blades. This is because although wood is flexible, it is heavier than PVC. It is also harder to achieve a balanced ratio with wooden blades. Durability for wooden blades isn’t as high as PVC blades. Wood isn’t moisture resistant unlike PVC. In the long run this contributes to increased wear and tear. When wooden blades absorb moisture, they loose their balance. They begin to wobble which affects efficiency. When wooden blades are subjected to strong winds, they may not hold up well due to limited resilience. This may further reduce efficiency for wind turbines that have wooden blades.

Pros of PVC Wind Turbine Blade

PVC represents better value for money. It is more durable than wood. PVC has a high resistance to moisture. The blades remain unaffected by constant exposure to moisture. They remain in good working condition for longer. This spares you from regular replacements. It helps keep your maintenance costs low. PVC blades are also more temperature resilient than wooden blades. The blades remain unaffected by frequent temperature fluctuations as long as sunlight isn’t too direct. In the long run, PVC blades are a more cost-effective option. It is easier to achieve proper balance of the wind turbine when PVC blades are used. This is because PVC blades balance better than wooden ones. This enables you to complete your project in less time. It also contributes to greater efficiency of the turbine


PVC is not a good choice in places that receive much direct sunlight. The material degrades quickly when subjected to direct sunlight for long. Constant exposure to the sun makes PVC brittle. This lowers resilience especially in the event of gusty winds. The blades eventually crack and must be replaced. Design options are also limited with PVC blades due to the hardness of the material.
