Wind Energy: How Blades Save the Planet Wind turbines are not just romantic windmills. Today, they are high-tech generators. Blades up to 100 meters long, the height of the tower is 150 meters. One turbine with a power of 2 MW can provide electricity for 1500 homes. In 2025, global wind energy produced 6% of all electricity (in Denmark - 50%, in Germany - 25%). Wind does not emit CO2, does not require water, does not create radioactive waste. Problems: noise, killing birds (rarely), disposal of blades (composite materials are not yet recyclable). The history of wind turbines: from mills to giants The first windmills appeared in Persia (7th century) - they ground grain. In Europe - in the 12th century. The Dutch drained swamps with their help. In the 19th century, windmills pumped water on farms. The first wind power station was built in 1891 in Denmark. Boom: after the oil crisis of the 1970s, interest grew. Modern giants (Vestas, Siemens Gamesa, General Electric) are building offshore wind turbines at sea, where the wind is stronger and more constant. How the wind blows from a scientific point of view Wind is the movement of air from an area of high pressure to an area of low pressure. The greater the pressure difference, the stronger the wind. Trades, monsoons, breezes, fens. Wind speed is measured in meters per second (m/s) or Beaufort scale points (0-12). The strongest wind on Earth is in Antarctica (up to 100 m/s). Our planet is covered with winds that carry heat and moisture, forming the climate. Wind energy in Russia Russia is a country with a huge wind potential (steppes, coastlines), but wind energy is underdeveloped. The first industrial wind power station with a capacity of 5 MW was built in 2019 in the Ulyanovsk region. Today, wind power stations are operating in the Rostov, Murmansk, Kaliningrad regions, and others. The share of wind in the country's energy balance is less than 1%. The reason is cheap gas and coal. But in 2026, a program to ... Read more
