Generally, we all know that wind turbines generate electricity using wind power, creating clean energy. However, if you were to ask most people how this process works, they’d be confused.
This is despite the fact that humans have been using wind energy for electricity since the 1800s and to power ships for much longer than that.
The number of wind farms around the world has also grown considerably over the years, along with the development of smaller operations.
All in all, wind power will continue to be an essential aspect of humanity’s energy mix going into the future.
Therefore it’s worth asking the question: how do wind turbines work step by step?
How Does a Wind Turbine Work? (Steps)
Types of Wind Turbines
Wind turbines come in two different designs; namely vertical axis turbines and horizontal axis turbines.
Vertical axis wind turbines are characterized by blades that turn parallel to the ground while horizontal axis wind turbine blades rotate perpendicular to the ground.
Horizontal Axis Wind Turbines
Horizontal axis wind turbines are divided further into two additional types; namely upwind and downwind.
Turbines can be upwind or downwind depending on the position of the blades to the tower structure that they’re connected to.
Thanks to tower turbulence, downwind turbines are often less efficient than upwind turbines.
Upwind turbines must be designed in a way that allows them to face the wind in order to improve efficiency.
A wind vane is what’s typically used to keep smaller turbines in place to face the wind while larger turbines have a motor and some sensors to achieve the same thing.
Vertical Axis Wind Turbines
Vertical axis wind turbines are considered to be the most efficient because they work regardless of the wind’s direction. Vertical axis turbines come in different types too.
There are eggbeater turbines or Darrieus which have aeroplane wing-like blades that move in a horizontal direction.
Meanwhile, Savonius turbines have cup-shaped blades that they use to effectively “catch” the wind. Each of these models has its own set of issues to be aware of, mostly pertaining to efficiency.
Wind turbines are complex pieces of machinery that are made of many different parts.
While this guide has been rather short and concise, we hope that it has covered the most essential aspects of wind turbine design and performance.
Hopefully, you can now answer questions like how fast do wind turbines spin or what is the best shape for a wind turbine blade.
This information will help you to better explain how wind turbines work to someone who’s a skeptic of renewable energy.
It’s important now more than ever for the human race to shift to more sustainable forms of energy like wind power in order to ensure the survival of our planet.
Fossil fuels are an obsolete form of energy that’s no longer sustainable for the longevity of the Earth and its inhabitants.
So it’s crucial that we continuously raise awareness about the benefits offered by wind turbines, and the only way to do that effectively is to be knowledgeable ourselves.
