液压传动系统中的节能技术主要是从减少系统能量损失和回收系统剩余能量两个方面来实现的。

Energy saving technique is mostly achieved by decreasing energy loss and recovering energy in the hydraulic transmission system.

风叶直接与动力传动系统连接，甩掉了包括变速箱在内的许多传动部件，后者往往容易产生断裂事故或造成能量损失。

The blades will attach to a drivetrain that does away with many of the moving parts, including the gearbox, that are prone to breakage and energy loss.

系统损失的能量也比较小。

So there's less energy expanded by the system.
