Why will wind energy become a new energy source?

1. Wind energy

Wind energy is a new energy source with great potential At the beginning of the 18th century, a violent wind swept across Britain and France, destroying 400 wind turbines. 800 houses, 100 churches, more than 400 sailboats, thousands of people were injured and 250,000 large trees were uprooted.

Simply speaking of uprooting a tree, wind generates 10 million horsepower (or 7.5 million kilowatts; one horsepower is 0.75 kilowatts) in just a few seconds! Earth's wind resources that can be used to generate electricity are approximately 10 billion kilowatts, almost 10 times the current hydroelectric generation capacity in the world.

Currently, the energy produced each year by burning coal worldwide is only a third of the energy provided by wind power in a year. This is why national and foreign governmentsangers attach great importance to the use of wind energy to produce electricity and develop new energy sources.

2. Seed diffusion

Wind is one of the environmental factors in agricultural production. Moderate wind speed plays an important role in improving the environmental conditions of agricultural land. Near-surface heat exchange, evapotranspiration from agricultural land, and carbon dioxide and oxygen transport processes in the air accelerate or intensify as wind speed increases. Wind can spread pollen and plant seeds, helping plants pollinate and reproduce.

Wind energy is a widely distributed and inexhaustible energy source. The monsoon prevailing in China is beneficial for the growth of crops. On the Inner Mongolia Plateau, the Northeast Plateau, the Southeast Coast and the mountainsInland areas, there are abundant wind energy resources that can be developed and used for energy.

3. Information indicators

Wind data is one of the important meteorological data, both in theoretical research and in various sectors of national economic construction, such as agriculture, transportation and construction. Industry, water conservation projects, reclamation and other departments are all indispensable. Wind is the horizontal movement of air and is a vector (or vector) represented by direction (wind direction) and speed (wind speed).

Wind direction refers to the direction the wind is coming from. Except for calm wind, it is expressed in 16 directions. Wind speed refers to the ratio of the distance the air travels to the time it takes to travel the distance. The unit is expressed in meters per secondof. It is observed regularly (the base station observes 4 times per day and the base station observes 24 times). times a day). Take a whole number and record it yourself with one decimal place.

The economic value of wind energy

The cost of generating electricity from wind has fallen so much that, even without other external costs, wind power is now cheaper than fuel-powered internal combustion engines in many suitable locations.

The annual growth rate of wind power generation was around 25% in 2002, and today it is growing rapidly at 38%. In 2003, the growth of wind power in the United States exceeded the average growth rate of all producers.

Since 2004, wind energy has become the cheapest of all new energy sources. In 2005, the costWind power has fallen to a fifth of what it was in the 1990s, and with the use of high-power generators, the cost of wind power has fallen. The downward trend will continue .
