2. Tidal power, also called tidal energy, is a form
of hydropower that converts the energy of tides into
useful forms of power mainly electricity.
3. Tidal power is extracted from the Earth's
oceanic tides; tidal forces are periodic variations in
gravitational attraction exerted by celestial bodies.
These forces create corresponding motions or currents
in the world's oceans..
4. The magnitude and character of this motion reflects the
changing positions of the Moon and Sun relative to the
Earth, the effects of Earth‘s rotation, and
local geography of the sea floor and coastlines.
5. -First: the movement of the waves is use to produce
energy.
-Second: the generators use the energy produce by the
movement of the waves to change it into electricity or
heat.
-Third: we use this energy in any way.
6. Tidal barrages : make use of the potential
energy in the difference in height between high and
low tides.
7. Dynamic tidal power is a theoretical generation
technology that would exploit an interaction between
potential and kinetic energies in tidal flows.

9. When the tide is high
it passes through the
turrbines that turn and
produce electricity. Then
The tank become to be
full.Next when there is
low tides the tank began
to empty and when the
water goes out it makes
The turbines turn and
Produce more electricity.

11. The country with the
most investment in tidal
power is the United
Kingdom.
Here in Spain there are
tidal power plants
inGalicia and in the the
Southwest of
Andalucía.
