Why Do Wind Farms Put Their Turbines So High Up?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do wind farms put their turbines so high up?

The Big Idea

Wind farms put their turbines way up high. They use tall towers and very long blades. There is a good reason!

Stronger Up High

Step one: stronger up high. Wind is stronger and steadier high above the ground. There are fewer trees and buildings to slow it.

Long Blades

Step two: long blades. Long blades sweep a larger circle and catch more wind. When the blades are twice as long, they catch about four times as much wind.

Giants

Step three: giants. Today's biggest turbines are taller than a fifty-story building. Their blades are longer than a jumbo jet's wingspan.

A Closer Look

Let's take a closer look! Near the ground, wind is weak. Higher up, it is stronger. Long blades catch more. Tall towers reach better wind.

Quick Facts

Quick facts! A single large turbine can power over a thousand homes. Twice the blade length catches about four times as much wind. The tallest are taller than a fifty-story building. Remember, their blades are longer than a jumbo jet's wingspan.

Think Like a Scientist

Now, think like a scientist! Cut two paper pinwheels. Give one short blades and one long blades. Spin them in front of a fan. Which one catches more wind? Then tell a friend what you found out.

Outro

Wind farms put turbines high up because the wind is stronger there, and long blades catch even more of it. That is why you see them on hills and out at sea, where the wind blows well. Science is amazing! Stay curious! Next time you see this in real life, remember what you learned today and smile! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books.
