Stepping back from the technical question of how to lay HVDC undersea, a globally connected power grid seems like a major win for renewable energy. There are a lot of places you’d like to put power plants, and having the infrastructure in place to be able to sell that energy makes it immediately more feasible. We could put nuclear plants anywhere. Solar plants across the Sahara. It would increase the energy available to developing countries without tempting them with dirty fossil fuel plants.
