"The world's largest tidal power station will be constructed off the coast of Incheon. GS Engineering and Construction signed a memorandum of understanding with state-run Korea Hydro and Nuclear Power (KHNP) on Wednesday and will begin construction later next year with a view to completion around 2017. The power station will have a capacity of 1.32 million kw/h, surpassing the 1 million kw/h of a nuclear reactor being constructed in Ulsan and 3.4 times greater than the capacity of the Rance Tidal Power Station in France, currently the world's largest. It will generate 2.41 billion kw per year, the equivalent of 60 percent of Incheon's household electricity consumption."

"The world's southernmost wind farm, in Antarctica, is now operational. The Ross Island wind farm will supply about 11 percent of the power to New Zealand's Scott Base and the American McMurdo Station. Previously, the two sites relied on diesel-powered generators for electricity. The wind farm will cut diesel consumption by about 463,000 liters a year and reduce carbon dioxide output by 1,370 tons annually, according to New Zealand-based Meridian Energy, the project's developer. The three turbines, each 37 meters tall and 33 meters wide, are generating 330 kilowatts of power."

"Wind energy could generate 20 percent of the electricity needed by households and businesses in the eastern half of the United States by 2024, but it would require up to $90 billion in investment, according to a government report released on Wednesday. For the 20 percent wind scenario to work, billions must be spent on installing wind towers on land and sea and about 22,000 miles of new high-tech power lines to carry the electricity to cities, according to the study from the Energy Department's National Renewable Energy Laboratory."
