Due to snowstorms and sharp temperature drops, some local power generation facilities failed, resulting in a sharp increase in electricity demand. The U.S. Department of Energy declared an energy emergency in Texas. In addition to electricity, U.S. natural gas supplies are also stretched. The snowstorm caused the natural gas pipeline to freeze, and many natural gas wells were forced to stop production. According to Bloomberg, the current decline in U.S. natural gas production is at an all-time high. Meanwhile, domestic demand for natural gas in the United States reached its highest level in nearly four years.
