Nowadays, the concept of new energy has deeply rooted in people's minds, and the whole world is developing clean new energy. Currently, electric energy is the most widely used. However, there are various ways of power generation now, including wind power generation, hydropower generation, and so on. Many people have seen wind turbines. Whether it is what we see with our own eyes or what we see on the internet, they are mostly white in color. Why?

1. Safer 

Generally speaking, except for snow, there are rarely white surfaces in nature. Painting the generator white can make it easier for the personnel in the air to distinguish. You know, wind turbines are very, very tall, with a tower height of 60 meters and a rotor diameter of 77 meters. If pilots fail to notice the wind turbines in time, there could be a danger. 

The white main body is relatively easy to distinguish. If you want it to be even more distinguishable, you can also paint a red mark at the tip of the leaf, which is called the identification band. This is not only aesthetically pleasing but also significantly improves the resolution. 

2. Lower cost 

The costs here are divided into two parts. One is to extend the lifespan of the machine itself, thereby indirectly reducing costs; the other is to lower the cost of manual maintenance. 

The wind turbine station is located in a wide area with strong wind. It is exposed to wind and sun every day. The excessively high environmental temperature will increase the temperature of the body, affecting the internal components. White can reflect all colors of light, reducing the range of temperature increase and the variation range, effectively protecting the internal components. At the same time, white is less affected by ultraviolet radiation, which can greatly prevent the machine from aging. 

The other factor is the cost of manual maintenance. The white color makes it easy for operators and maintenance personnel to quickly detect oil or damage, allowing for prompt cleaning and maintenance. Moreover, the white coating can also reduce manufacturing and maintenance costs. 

Now, do you know why wind turbines are painted white?
