Abstract
Tidal stream power is renewable energy which is free from hydrocarbon energy source and CO2 emission. In Japan, we have several narrow passages with strong tidal current, more than 10 knots in some cases, and tidal stream power may be utilized in the future, which contributes to reduction of global warming gas. In this paper, we estimate distribution of tidal stream power density in several narrow passages and Setonaikai in Japan from amplitude of M2 and S2 constituents of tidal stream.
