The copper need not be thicker, but the insulation might need to be

Exactly. More energy means either more copper or more rubber in the cable.

    Rubber is cheap though, and flexible. If it's the size of a gas pump hose, oh well; gas pump hoses are also rubber. As long as they don't have to make the copper ridiculously thick, it shouldn't matter how thick the cable overall is
