0 1 Trend of technical development (Korea) Tidal Power 1980 s Check the validity of tidal power generation in the west coast (Garolim Bay) 1993 B/C = 0. 84 (not economical) delayed 2004 Sihwaho Lake ; fresh water sea water 2005 Garolim Bay detailed investigation 2011 Environmental effects evaluation
0 1 Tidal Power plant Tidal Power
0 1 Tidal Power strength weakness - No exhaustion - Low energy density - Clean energy - Intermittent - Small size of turbine - Expensive ( than wind power ) - Limitation on location
