Wind, of all the alternative energy sources we pay attention to, requires vast areas for generation. So water has become the go-to place to place the turbines. It looks like the new race is whether to have the turbines fixed or floating:

Floating wind turbines could open up vast ocean tracts for renewable power

Technology could help power a clean energy transition if it can overcome hurdles of cost, design and opposition from fishing

In the stormy waters of the North Sea, 15 miles off the coast of Aberdeenshire, in Scotland, five floating offshore wind turbines stretch 574 feet (175 metres) above the water. The world's first floating windfarm, a 30 megawatt facility run by the Norwegian company Equinor, has only been in operation since 2017 but has already broken UK records for energy output.
