How energy is produced
• Tidal energy is produced through the use of tidal energy
generators. These large underwater turbines are placed
in areas with high tidal movements, and are designed to
capture the kinetic motion of the surging ocean tides to
How energy is harnessed
• A tidal barrage is created at the mouth of a river or other
choke point that connects to the ocean.
• In flood tidal power generation below the water level
there are opening in this barrage that have turbines in
• These turbines are powered when the tide goes in or the
water level rises.
• Once you’ve built it, tidal power is free
• It produces no greenhouse gases or other waste
• Requires no fuel
• Reliably produces electricity
• Maintenance isn’t costly
• Tides are predictable
• Inexpensive turbines that don’t harm the
• There are a limited amount of places for
these tidal barrages.
• When the tide is moving correctly, it only
produces power for 10 hours each day.
• When built across an estuary, it affects the
– Birds rely on the tides to move mud for
– Fish use them to migrate
How tides work
• The moons
pulls on the ocean
• When the moon is
right above one side
of the earth or the
opposite side, the
area will experience
Bay of Fundy
• Located on the
Atlantic coast of North
Canada and the U.S.
• It has one of the
highest vertical tidal
ranges in the world.
• A good place for tidal
turbines because the
tides are very strong
and be used to
produce a large
amount of energy.
