Heavier blades can have both benefits and drawbacks, depending on how they are designed and used. In general, blades need to be strong enough to capture wind energy and transfer it to the turbine. A heavier blade may seem like it could capture more wind, but it doesn't always mean better performance.

When blades are too heavy, they put more stress on the entire turbine system, especially the tower and the rotating parts. This can cause wear and tear over time, leading to more maintenance. Heavier blades also take more energy to start spinning, which can lower the turbine's efficiency, especially in areas with low or medium wind speeds.

However, if designed properly, a slightly heavier blade with the right shape and structure can improve power output in high-wind areas. These blades can be more durable and stable, which helps in strong wind conditions.

In short, it's not just about weight—it’s about balance. The goal is to design blades that are light enough to be efficient but strong enough to perform well. Engineers use advanced materials to keep the blades both lightweight and powerful.
