What material is made the power cable ? I thought copper was getting more and more expensive ?

Some use Copper, but usually Aluminium is used.

Aluminium is far less dense, which in turn makes the whole cable bigger, which has other costs (eg. fewer kilometers of cable fit in a boat). Usually it's still the best choice overall though.
