Hydraulics in Renewable Energy

By doing this, the hydraulics are used as an auxiliary energy storage device. This means that hydraulic fluids are stored in the accumulators, and when the pressure from the system is released, the angle of the blade can change. By changing the angle of the blade, hydraulics optimize the amount of energy accumulated in different wind conditions.
