Verdant Power has installed an array of three tidal power turbines at its Roosevelt Island site in New York City’s East River–a tidal strait with strong water currents that change direction between flood and ebb tides approximately four times each day. The turbines are mounted on a frame that’s lowered to the bottom of the river. As the tide shifts direction, they turn to generate power from the current flowing in the opposite direction. This cycle repeats in a very predictable manner approximately every 6 hours. The regular nature of tidal currents provides a significant advantage for tidal power as compared to other, less predictable resources like wind and solar power. The potential for tidal energy may be 250 gigawatts around the world, enough to power 250 million homes for a year.
