Yes, they use pine. Your comment is vacuous as pine is a structural material and has specific properties, possibly better understood than those of eucalypt hardwood. Properly specified, treated, installed and maintained you could make power poles out of cardboard.
The failed poles are very old, probably had only basic creosote rot treatment and likely were weakened by drill holes checking for rot. The steel support posts alone indicate that the power company knew the posts were near end-of-life.
Like anything, specification is vital. You could run a car or a state on torch batteries (Tesla) if desired.
If you had endless money and not a lot of need for profit you could turn a submerged cork on a string into a power plant.
The real money is in solar panels, batteries and islanded grids, not some bobbing cork with limited installation opportunities in a harsh marine environment.
