Course Level 2: Intermediate
Estimated Study Time: 2-3 hours
The rise and fall of ocean tides result from the combined gravitational pull on water by the Moon and, to a lesser extent, the Sun, which exerts a force on water directed towards the two astronomical bodies. These gravitational effects combine with centrifugal forces that result from the Earth and the Moon orbiting each other. All of which makes tidal change a complex process. This course considers the power of the ocean tides as a potential source of useble energy and whether or not it can ever make any significant contribution to global energy supplies.
