The ocean current in the sea around Taiwan is a reliable, self-generating, and clean source of energy that should not be overlooked. This article describes the probability distribution of current velocity and the potential spatial distribution of current energy in the region around Taiwan, while introducing recent international developments in ocean current generator technology. By using ocean current generators of low rated speed in accordance with observed and simulated ocean current data, we are in the process of developing ducted turbines that can be used for ocean current power generation in an effort to increase the efficiency of the generators as well as the economic value of their development and utilization.
