Ocean Current Energy can convert the forces that drive global climate directly into electricity. The Gulf Stream passes by the Miami electricity market. Estimates of recoverable energy range to 10 giga watts. @ 4-5 cents per kilowatt.

Ok, ocean hydro is technically feasible. But if there really is a 10-20 year decline in temps, there are going to be lots of lawsuits against such efforts.

Suppose such a plant was built in the Gulf Stream off Florida's East Coast. It won't take long into a cold spell before folks from New York to Greenland to France are complaining that it's stealing heat from them by sucking energy==heat from the Gulf Stream.

Like nuclear power plants in the USA, I do think the primary cost for such ocean hydro might be for lawyers.
