The southern United States has received its heaviest snowfall in ten years. Why does snowfall cause power outages?

The reason why snowfall causes power outages is because a large amount of snow adheres to the wires, which puts too much pressure on the wires and can easily break them.

On January 10, 2021, a rare snowstorm swept across the southern region of the United States, ushering in blizzard weather. In some severe areas, precipitation reached as high as 22 centimeters. The precipitation in Waco, Texas reached 11cm on January 10, 2021, breaking the single-day snowfall record set in 1973. According to local weather reports, the storm will continue for a long time and move toward the southeast of the United States. 1. Heavy snowfall in the United States

In addition, this rare heavy snow weather also caused power outages in large areas of the southern United States.

Why does snow cause power outages?

It is very common for snow to cause power outages, not only in the United States, but also in China. There are two main reasons why power outages are easy to occur during snowfall. First, a large amount of ice and snow attached to the wires will put great pressure on the wires, causing them to be broken. Secondly, when the weather gets better, the sewage left when the ice and snow melts can easily cause pollution flashover of the power grid protection device. In this case, the device protecting the line will trip, resulting in what we often call a power outage. There are also many claims that are credible. Many areas rely on coal to generate electricity. Bad weather makes coal transportation difficult and thermal power plants cannot generate electricity. Winter is the dry season, and those who use hydropower to generate electricity will decrease accordingly. When the weather is cold, residents' electricity consumption will increase sharply, which will lead to power shortages. This situation often occurs in summer.

Although the 21st century has ushered in an era of peace, people's living and consumption levels are also constantly improving. People mostly rely on wind and water power to generate electricity, which does not need to consume too many resources, but it can save electricity. , saving water is still what we should do.
