WebThe current energy is generated through the use of ocean current turbines, which harness the kinetic energy of ocean currents to generate electricity. Ocean currents are driven by temperature gradients, the Earth's rotation, and other oceanographic processes, and they contain vast amounts of energy that can be harnessed to generate electricity. WebOcean and atmospheric circulation play an essential role in sustaining life by moderating climate over much of Earth's surface. An important part of the circulation of heat and freshwater and other sea water constituents are ocean surface currents. Their strength and variability play a role in weather and climate, impact environments for all life on Earth.
