In China, the longest ultrahigh-voltage power line stretches more than 2,000 miles from the far northwest to the populous southeast — the equivalent of transmitting electricity from Idaho to New York City.

China has 41 others. Each is capable of carrying more electricity than any utility transmission line in the United States. That’s partly because China is using technology that makes its lines far more efficient than almost anywhere else in the world.

Many of China’s ultrahigh-voltage lines use direct current technology, which allows them to carry electricity for long distances with barely any of the transmission losses that affect most high-power lines in other countries.
