The world's first tidal-electric turbine has been connected to the Irish power grid. Powering 150 homes during the break-in period and 1500 once it's up to full capacity, this is a small step toward true renewable energy production. As an added bonus, the turbines rotate at 10-15 rpm so they're unlikely to cause "problems" with sea life.
