Long electric feeds lossy, not necesarily
We have an AC feed from the mainland of British Columbia to Vancouver Island. Before leaving the mainland it is converted to high voltage DC and then reconverted back to AC on arrival on Vancouver Island. The losses associated with capacitance and inductance coupling into the sea water is averted and the use of high voltage to transport the power means less losses due to resistance. I'm sure that similar methodologies could be incorporated into offshore wind power installations. Where there is a will and a need there is a way.
