Tidal Energy

Green Energy:

  • Tidal Energy is Inexhaustible
    • Tides occur due to gravitational field interactions of the Earth with the Sun and Moon
    • Potential difference is the source of tidal power generation
  • “Free Energy”
    • The gravitational field interactions will not expire, and so once a tidal energy system is setup, the resulting power being generated is free
    • Due to the predictability of tidal energy, system construction is much simpler and easily modelled
    • Tidal systems are quite similar to wind turbine systems, except that they receive energy from flowing water
      • Water is about 1000x denser than air, which means electricity can still be generated at very low speeds
  • Environmentally friendly
    • The are no climate gas emissions from Tidal systems and they do not take up a lot of space
    • Unfortunately, due to the low amount of real world examples of such systems, environment effects have not been thoroughly investigated

Technology Advancement:

  • Tidal energy has not grown as much as other forms of renewable energy, but the industry is recently starting grow
  • In 1966 the world’s first tidal barrage La Rance Station was implemented in France
    • This plant is the world’s largest tidal plant to date and it is rated capacity is 260 MW
  • New models for tidal facilities have recently been conceptualized, but none are currently commercially operational:
    • Tidal lagoons
    • Tidal fences
    • Underwater Tidal turbines
