Two types of tidal energy can be extracted: kinetic energy of currents between ebbing and surging tides and potential energy from the difference in height between high and low tides. All coastal areas experience high and low tide. If the difference between high and low tides is more than 16 feet, The differences can be used to produce electricity. There are approximately 40 sites on earth where tidal differences are sufficient. Tidal energy is more reliable than wave energy because it based on the moon and we can predict them. It is intermittent, generating energy for only 6-12 hours in each 24 hour period, so demand for energy will not always be in line with supply. RENEWABLE ENERGY : Tidal power Benefits of tidal power generation include Predictable source of clean energy No dependence on foreign fuel sources Flood protection Transport links for road and/or rail Better shipping and boating conditions behind the barrier Disadvantages include The timing of the tides doesn’t often correlate with peak demand times(less of a problem if there are good energy storage options available ) Existing ecosystems behind the barrage tend to be heavily altered Enhance flood risk on the seaward side Shipping would have to navigate locks Industrial discharges behind the barrage are less likely to be dispersed out to sea RENEWABLE ENERGY : Tidal power, KOREA Tide Spring Station Area embank range capacity [km2] ment [m] [GMh] [km] Sihwa 7.8 56.5 12.67 552 Ganghwa 8.97 84.9 8.34 1,556 Incheon 7.3 106 16.9 2,414 Sihwa Ganghwa Incheon RENEWABLE ENERGY : Tidal power, CHILE Potential region Energy potential Chacao, Magallanes 164.9GW Coastline of Chile Expect possibility 4,270km of development Source : CNE, Garrad Hassan & Partners Limited Development potential Capacity of generate Annual energy [MW] production [GWH] Chacao tidal power 150~200 500~1000 generation Sihwa tidal power 254 552 generation RENEWABLE ENERGY : Tidal power, Trend of Research Impact of different operating modes Operational planning of an Evaluation of vertical axis turbine for a Severn Barrage on the tidal independent micro-grid characteristics for tidal current power and flood inundation in the containing tidal power generators, power plant based on in situ Severn Estuary, UK, 2010 SOFCs, and photovoltaics), 2013 experiment, 2013 RENEWABLE ENERGY : Wind power Wind turbines are systems that harness the kinetic energy of the wind for useful power. Wind flows over the rotor of a wind turbine, causing it to rotate on a shaft. The resulting shaft power can be used for mechanical work, like pumping water, or to turn a generator to produce electrical power.
