China’s Power Advantage: Fueling Electric Cars and High-Speed Trains
China is leading the world in powering electric vehicles and high-speed trains through ultra-high-voltage direct current (UHVDC) transmission lines. These power lines carry more electricity than any in the United States, thanks to cutting-edge technology that makes them highly efficient.
By using UHVDC lines, China transmits massive amounts of electricity across vast distances with minimal loss. This power supports not only its growing fleet of electric cars but also its high-speed rail network, including trains that reach speeds of up to 400 km/h.
Many of these lines are fed by renewable sources such as solar and wind, helping China reduce its dependence on fossil fuels. This efficient energy backbone enables sustainable transportation at scale, supporting both urban mobility and intercity travel.
China’s advanced grid technology showcases how infrastructure investment can drive clean energy adoption, setting a global example for future transportation and energy systems.
