Today’s post is dedicated to the awesomeness of wind turbines! Maybe you’ve seen pictures of enormous extraterrestrial-like fans that are the size of some skyscrapers. Maybe you thought to yourself, “What in the world is that?”
Don’t worry, you’re not alone. I definitely had this moment when I saw a picture of a wind turbine for the first time.
What Are They?
Although wind turbines look like great big fans, they’re actually quite the opposite. They are ingenious inventions created to produce electricity from the wind, not use electricity to create the wind.
The blades, as you can see in the picture below, turn when the wind pushes them, obviously. When this happens, the blades are actually turning a shaft that is connected to a generator. This amazing generator then takes the wind’s kinetic energy and voilá: electricity.
Why Do We Need Them?
For starters, these babies help the environment by being a fossil fuel alternative. The wind is, in a sense, limitless. Even better, it’s affordable! We don’t have to continuously plow through Mother Earth for a limited resource. Instead, we can place a wind turbine in the place of a coal mine and get affordable energy.
Wind turbines don’t pollute or contribute to carbon emissions. They’re pretty amazing and, in my opinion, a lot better to look at than this mine:
Not to mention, wind energy is a lucrative business that offers thousands of jobs and helps many economies, including the economy of the United States. If you would like to know more about wind energy, the science, as well as the extended benefits, click here.
