The only way to have non-wasteful DC outlets would be to have power plants dedicated to generating DC current, and the issue with that is DC power suffers from severe voltage drop over a much shorter distance than AC current. That's one reason we adopted Tesla's AC over Edison's DC at the beginning of the 1900s.
