Wind Power

Wind (Aeolian) Power

​Wind Power

Wind power comes from moving air.

Large wind turbines use the wind to spin a generator that creates electricity.

Inside the wind turbine are two long shafts that spin around.

One is a low speed shaft that the turbine spins and is connected to a gearbox.

There is also a high speed shaft that is connected to one side of the gearbox. The gearbox makes it spin faster.

The high speed shaft turns the generator.

• The wind turns the blades.

• The blades turn the low-speed shaft.

• The low speed shaft spins and is connected to the gearbox.

• The gearbox speeds up the the shaft.

• The high speed shaft now spins faster which turns the generator.

• The generator spins to make electricity.

​Wind turbines can be placed offshore. This means that they are located in the water near the land. There are usually strong wind currents located just off the coast.

Offshore Wind Turbine

​Wind turbines can be placed on land. They can be placed in locations that have strong wind currents.

​​Onshore Wind Turbine

​As of February 2020, there 361 onshore and 22 offshore wind turbines in Taiwan.

Currently, around 5% of electricity in Taiwan comes from wind power.
