1.Ocean currents: New source of renewable energy
Ocean
currents, a source of energy that is gonna add up to the list of renewable energy sources in
the years to come. Turbines placed beneath the ocean are able to rotate with the help of forces acting upon
them, such as breaking waves, winds, tides caused by gravitational pull of sun
and moon. These spirals developing beneath are able to generate mechanical energy
that makes turbines to rotate, which cuts the magnetic flux. According to
Faraday law, whenever a conductor is placed in the region of time changing magnetic
field an EMF is induced into the conductor. This results in current in conductor
which is valuable.
