Harvesting Wind Power 

Sustainability is the capacity to endure. 

Healthy ecosystems and environments are vital for the survival of humans and other organisms. However, human activities have had a significant negative impact on the environment. To address this, people worldwide recognize the urgent need to secure a better future for the present generation and safeguard the well-being of future generations. 

In this section, we will explore the importance of protecting our environment for future generations and the role of skilled and forward-thinking engineers in achieving this goal. 

Renewable energy is a crucial step towards mitigating the global rise in temperatures. Renewable energy sources, such as solar and wind power, do not emit carbon dioxide and other greenhouse gases responsible for global warming. 

Why Does Wind Blow? 

Wind is generated because warm air is lighter than cold air, causing it to rise, while cold air sinks. This movement of air is what we refer to as wind. 

Fascinating Wind Facts 

• Wind energy is clean and renewable. 
• Windmills have a rich history dating back to 2000 BC in China. 

• Sailors once harnessed wind energy. 
• Farmers used windmills for grinding grains and pumping water. 
• Wind turbines are a common sight today, generating electricity from the wind. 
• A collection of wind turbines is known as a wind farm. 
• A single wind turbine can power up to 500 homes. 

• Wind turbines can reach heights of up to 200 meters with blades spanning 60 meters. 
• Small turbines are sometimes used for charging batteries or as backup power in caravans.

What is a Wind Turbine? 

A wind turbine is a device that converts wind’s kinetic energy into electricity. Wind turbines play a crucial role in Scotland’s energy landscape, providing enough energy from wind farms to power two entire Scotlands! 

What is a Windmill? 

A windmill transforms wind’s kinetic energy into mechanical energy. Historically, farmers used windmills for grinding grains and pumping water. 

Now, you can try your hand at making your own windmill. The video below demonstrates how to do this, and we also offer a Make Your Own Windmill Worksheet to assist you.
