Definition of Wind Power

Wind Energy, also known as Wind Power, is becoming a more and more popular renewable energy source. Before starting in wind energy, you must make sure you checked every aspect of it.

The potential for wind energy is vast, and experts say wind power can easily supply more than 20% of the world’s electricity. This article guides you to learn the definition of wind power, the history of it, and what might happen in the future from the point of wind energy. Thanks to that, you can predict the future of wind energy and its effects.

Wind power is also one of the forms of renewable energies, and we can gather it by using airflow in the atmosphere. This process happens when wind power turns the fan blade on a wind turbine which accumulates electricity.

Regardless of different sizes and types of wind turbines, every one of them generates electricity with the same procedure. The harnessed energy type is kinetic energy. Wind energy is harnessed when the wind blows thanks to the blades of the turbine and transferred into mechanical power. Then, energy generation occurs when this mechanical power is used to spin a shaft connected to a generator.

History of Wind Power

Though it may seem a modern technology, capturing the power of the wind is an ancient method. Even in the 5000 B.C.E, according to the records, some civilizations harnessed the power of the wind. For example, the ancient Egyptians used the wind power to guide their boats on the Nile river. Also, people have used windmills on domestic affairs, such as pumping water and grinding grains. For the usage of wind turbines, however, the first records of using wind turbines to generate electricity occurred in the 19th century.

The first building in history which powered by wind energy was in 1887. A professor named James Blyth constructed a small wind turbine in his garden in Scotland. He used 10 meters tall cloth sails for his wind turbine. And this turbine used wind power to charge accumulators and provide electricity for his little hut. After a while, Blyth both able to power his own home and share this energy with his neighbours. Thanks to James Blyth’s invention, from the United States to Denmark, wind turbines were being used to generate electricity all over the world. In the 20th century, its use became more frequent and even started to compete with conventional energies like coal or oil.

Global Correspond of Wind Power

Wind technology is a great alternative energy resource. Unfortunately, in 2015, wind powers made up only 4 per cent of the world’s electricity. As for windy countries, this number is as high as 40 per cent. Experts estimate that these numbers are going to grow in the coming years.

Wind Power and It’s Future

The future of wind power looks bright even though it has some downtrends associated with it. Due to climate change becomes a more severe and specific problem, people are approaching environmentally friendly energy alternatives. According to GWEC, In 2018, global wind power capacity expanded 9.6% to 591 GW. And Denmark is the country with the highest usage of wind power, with 43% of its consumed electricity came from wind power in 2017. These numbers indicate that, in the future, electricity costs will reduce.
