No, DC is more efficient over long distances than AC. AC transmission has huge losses due to capacitive effects caused by the alternating current.

AC also has WORSE voltage drop than DC because it exhibits something called the skin effect that causes the middle of your cable to not be used as much to carry current.

Tesla triumphed over Edison because we didn’t have the technology to step between voltages back then. DC transformers are still incredibly expensive. AC transformers are coils of wires.
