Tidal Power As Alternative Energy

Biofuels, Wind or solar power are the popularly known alternative energy.

What is least known is the recent commercialization of tidal power or tidal energy-(wikipedia) “form of hydropower that converts the energy of tides into electricity or other useful forms of power.”

A schematic of how tidal power runs looks like this…

What we’d like to emphasis is-innovation is a natural product of the markets- where rising energy prices has opened the avenues for (substitutes) alternative energy sourced from mother earth.

A short excerpt…

``The world's first commercial tidal-power system has been connected to the National Grid in Northern Ireland. Built by the British tidal-energy company Marine Current Technologies (MCT), the 1.2-megawatt system consists of two submerged turbines that are harvesting energy from Strangford Lough's tidal currents. The company expects that once the system, called SeaGen, is fully operational, it will be able to provide electricity to approximately one thousand homes.

``The system is currently being tested and has briefly generated 150 kilowatts of power into the grid. But it has also damaged one of its rotors due to a failure in the control system when the rotor began turning too fast. Although the problem was a minor setback, the unit is not expected to start running continuously and at full capacity until November, says Peter Fraenkel, the technical director at MCT.

``The technology works like a wind turbine, but instead of wind, the turbines are driven by the flow of tidal currents. It offers a significant advantage over wind because currents are predictable, says James Taylor, the general manager of environmental planning and monitoring at Nova Scotia Power, a company that also has plans for a one-megawatt tidal-power project. "Wind is intermittent and, because of that, is much more difficult and expensive to integrate in a power system," he says.
