The tides of our oceans ebb and flow. The swift currents under the ocean surface also have tremendous kinetic energy. This presents possibilities
of harnessing the energy of the moving water. Several countries such as France and Canada have harnessed tidal power to produce electricity. The two most common methods tap the ebb and flow of the tides in bays and the undersea currents with sea turbines. See more below.
This form of hydro energy comes from the conversion of gravitational potential energy to kinetic energy. Wate falls from high potential of mgh and transfers this stored energy into moving energy --kinetic energy. Kinetic energy equals mv ²/2 . The moving water does work -- Work Energy Theorem. This theorem states that Net Work equals change in Kinetic Energy. When the water strikes a turbine, the vanes of the turbine slow the water converting the energy into work to turn the turbine. Many "waterfalls" are created by hydro-electric dams. Check below to see how electricity is generated!
Some of the gravitational potential energy in this waterfall is also converted into thermal energy as well as kinetic energy.
