Fossil fuels include coal, petroleum, and natural gas. usage, some small companies in the US are using the power of sea tides. Champions of tidal power tidal power Electricity produced by turbines operated by tide flow. Large amounts of power are potentially available from the tides in certain locations, such as Canada's Bay of Fundy, where the tidal range reaches more than 50 ft (15 m), but this potential power is not say the technology is "wind turbines on steroids", spinning like windmills The List of windmills is a link page for any windmill or windpump.

Verdant Power Verdant Power is a maker and installer of tidal power and hydroelectric systems. Their primary device is an underwater turbine, similar to a three-bladed wind turbine, that is designed to capture energy from tidal currents and (precipitation-driven) river currents. on New York's East River is a case in point. The company is installing two underwater propeller-type turbines in a small pilot project and will spend the next 18 months studying the effects of the prototype on fish. If the results are positive, a further four turbines will be added. "If all goes well," says company co-founder Trey Taylor, "we could have about 300 turbines in the river by 2008." |
