Renewables are great but offshore wind is currently the most expensive renewable by several times.

The major problem is the cost of the undersea cables, which cost millions per mile.

A land based wind turbine costs around 1.3-2.2 million per MW of capacity. It costs 5 times that per mile of undersea cable. Not including the turbine itself.

It would really help if someone could come up with a new way to run those cables that was a reasonable cost. That would hugely increase the rate of offshore wind adoption.
