Question

how do currents generate electricity

Answer 1

Strong ocean currents are generated from a combination of temperature, wind, salinity, bathymetry, and the rotation of the earth. ... The kinetic energy of marine currents can be converted in much the same way that a wind turbine extracts energy from the wind, using various types of open-flow rotors.

Technologies are being developed so that energy that can be extracted from ocean currents and converted to usable power. Ocean waters are constantly on the move. Ocean currents flow in complex patterns affected by wind, water salinity, temperature, topography of the ocean floor, and the earth's rotation.
