TIDAL eNERGY

What is tidal Energy?

• Form of hydro power
• Basically takes advantage of the back and forth movement of the ocean
• Can be harnessed in various ways
• Not only done in oceans
• It is a huge and ongoing method of energy

Kinetic tidal power

• Uses the energy captured from waves during the high and ebb tides
• It's using energy that is currently in motion
• Will only work when tides have a great enough energy 

turbines

• Uses the energy captured from waves during the high and ebb tides
• Uses a turbine that is spun 
• The turbine will spin a coil

Push plates

• The concept is to not use conventional methods
• Uses push plates, chains and generator shaft 
• Still in planning stages
• Uses kinetic energy

Untitled Slide

biowave

• New method of tidal harnessing 
• Still in tests
• Low costs
• High efficiency rates
• Converts mechanical energy to fluid pressure

pros of tidal energy

• Produces no primary or secondary pollutants 
• Requires no fuel and is a lot more reliable
• Easy to calculate when production will be high or low
• Vertical axis is highly efficient and cheap
• Provides new and innovative ways of gathering

Cons of tidal energy

• Affects estuary diversity and populations
• Bird feeding is disrupted
• Fish migrations disrupted (Fish ladders) 
• On average will provide 10 hours of energy per day
• Few actual high productivity sites available on earth
