Harnessing the Wind: The Role of Windmills in Renewable Energy



Do not mistake them for giants and charge at them with your lance. Windmills may be tall, but their sleek blades are quite graceful in the wind.

Kinetic energy is the energy of an object in motion, in this case fluid. 

Fluids are substances that can flow and take shape of their container.

A turbine is a device that utilises the kinetic energy of a fluid such as water, steam, or air.

Turbines are used in various applications, including wind turbines, hydroelectric turbines, and steam turbines.

A windmill is a wind turbine. A windmill is a towering pole with a rotor and blades sticking off the top side.

The rotor and blades resemble a ceiling fan with pointy blades.

Inside the casing of the windmill, behind the rotor is a generator that converts wind into electricity, which is then fed through a power cable down the pole. The pole is called the tower.

As the wind blows, it propels the turbine’s blades, which in turn rotate a generator, producing electricity. The generator converts the mechanical energy from the rotating blades into electrical energy.

A Brief History of Windmills

The present conversation is all about renewable energy. We are so solar focused, but we must look to all renewable energy to truly understand the story behind our solar powered future. 

Windmills’ rich and fascinating history will be explored, it is one that spans thousands of years.

The earliest known windmills were developed in ancient Persia around the 7th century.

These early windmills had vertical sails attached to a central vertical shaft. The ancients used them for grinding grain and pumping water.

Windmill technology slowly appeared all over the world.

In the Middle Ages, windmills became common in Europe. They were particularly found in the Netherlands. These Dutch windmills were used for a wide range of purposes. These included milling grain, sawing wood, and draining water from low-lying areas.

During the 19th century, windmill design advanced. Horizontal-axis windmills with rotating blades that were far more efficient than their vertical sail counterparts. These windmills could generate power for industrial applications. For example, powering machinery in factories and mills.

Today, wind turbines are a vital part of the global renewable energy landscape, as they provide clean and sustainable electricity.
