What is the main goal of Tidal and
          Wave Power?


• The main goal of Tidal and Wave Power is
  to capture the power generated by the
  waves and produce hydroelectric power.
  What is the overall potential in
“making a difference” to the world?

   • Cheap energy

   • Renewable

   • No greenhouse gasses

   • Reliable
          How it Functions/Operates
• Ebb generation-Water fills a basin through the
  sluice gate (at high tide) until it is full; at which
  time the gates are closed. After the tide goes
  out, the gates are opened and the turbines
  capture the energy.

          How could technology stall mass
                implementation?
• Building underwater turbines to tolerate the force of
  the water
• Finding a structures that can produce the optimum
  amount of power while not disrupting the
  environment
• Pre-testing for the different types of wave energy
  generators takes a long time and is a difficult
  process

Political/economical obstacles that
     could stall implementation
• High capital cost and low running cost
• Lag time before investment return
• High irreversible commitment

Negative Environmental Impact
• Sea life affected
  – The tidal fences that capture energy also trap
    larger sea life
  – Turbines could kill fish if they get too close
