Information about new forms of renewable energy seems to come out in waves. A few months ago, solar was everywhere. Now, I’m seeing a lot about energy derived from water. In particular, two projects caught my eye, one in Ireland and the other in South Korea. Both operate on the premise of harnessing the power of fast-moving tidal streams to generate electricity.
In Northern Ireland, Marine Current Turbines is planning to have the world’s first tidal stream device up and running this Monday. The SeaGen turbine is being installed in the mouth of Strangford Lough – one of the fastest tidal flows – giving it the capacity to provide sustainable electricity to about 1,000 homes. The company believes it can improve the technology significantly, so that one turbine could power over 400,000 homes by 2015.
The other project, still in concept phase, is a joint venture between British tidal power company Lunar Energy and Korean Midland Power Company. They hope to build a field of 300 60ft.-high turbines on the sea floor off the coast of South Korea. But, the Korean authorities require a testing phase on one turbine before the whole scheme is allowed to be implemented, so testing won’t commence until at least next year. The finished product would provide electricity for 200,000 homes by 2015.
There’s a clear trend that the world is embracing alternative sources of clean, renewable, zero emission power sources now more than ever. By utilizing energy generated from wind, solar, and water, how long will it be before we can live completely off the grid?
