The world’s largest tidal turbine, weighing 1000 tonnes, has been installed in Northern Ireland’s Strangford Lough. The tidal turbine is rated at 1.2 megawatts, which is enough to power a thousand local homes. It was built by Marine Current Turbines, and it will be the first commercial tidal turbine to produce energy, when it begins operation later this year. The turbine has twin rotors measuring 16 meters in diameter. The rotors will operate for up to 18-20 hours per day to produce enough clean, green electricity.
