    The Three Gorges power plant, China's largest hydropower project, generated a record 98.1 billion kilowatt-hours (kwh) of electricity in 2012, according to an official announcement.

    The power generation volume grew 25 per cent year-on-year and accounted for about 14 per cent of the country's total power generated by hydropower plants in the same year.

    By the end of 2012, the plant had generated 629.1 billion kwh of electricity, equivalent to a reduction of nearly 500 million tonnes of carbon dioxide, state-run Xinhua news agency reported.

    The Three Gorges Project, launched in 1993 with a budget equivalent to $22.5 billion consists of a dam and a five-tier ship dock, in addition to the 32 generators.

    The dam's first generator went into operation on July 10, 2003.

    The last generator started operating last July, realizing a combined generating capacity of 22.5 million kilowatts.

    The Three Gorges Project generates electricity, controls flooding by providing storage for water and adjusts shipping capacity on the Yangtze River, China's longest waterway.

    It is gonna take decades before we are sure if this problem has been solved.

    Constructions of huge dams of this scale should be discouraged, because too many uncertainties are on the table.

    Some say silt is inevitable for most dams. so gradually the dam phases out its reservoir capacity for power generation and navigation.

    wiki says the cost is 22 Billion and the installed power production capacity is around 22,500 MW.

    Looks cost effective, compared to nuclear power.

    It depends on the attitude of DFI's administrators.

    The potential cost might be higher and couldn't be calculated with figures.

    The Three Gorges dam has been a very controversial project in China since the very beginning of its planning, and even after it was almost finished. Not everyone in China approves of it, some had been opposing that dam until their deaths.

    Chinese hydraulics expert Huang Wanli is one of the most prominent opponents. In 1950s, when China decided to build a dam spaning Yellow river, he voiced his different oppinion and predicted the dam would be a disaster which was unfortunately confirmed 4 years after the completion of the dam. That dam has been a headache of China since then, Huang was persecuted afterwards.

    In 1980s, he learned the government was planning Three Gorges dam, he once again expressed his strong opposition and claimed that " people will eventually be forced to blow off that dam", many believed him. But the decision of building the dam still got approved in 1992 after a National People's Congress session by a vote of 1767 to 177, with 664 abstentions. That is a lof of abstentions.

    Huang could be right again!

    It is really hard to tell in current stage since it may take decades for people to see the impact. Considering the money and lives costed by the floods and the possibility of flood every year, I reall don't think Chinese gov and the people living in that area care too much about environmental expenses for the time bing!

    I am not so sure!
    He didn't participate any ground research work on yangtse river. Comparing to him, I would give more credit to those who spent decades on data collection and analysis around the whole yangtse river. Untill today, the status of dam at least proved that he really know little about this area.

    Dont' you feel it ? It's affecting you too. Days are now longer because of this dam!

    It seems because this dam has raised trillions of Kilo grams of water above the sea level to a significant height, the moment of inertia of Earth has increased making Earth to rotate slower and making days longer (~0.06 micro seconds ) Damn you Chinese :D

    when you choose to build the dam you know you will be faced with many problems.....but for a developing country these is no much too choose......keep being poor and leaving people with no electricity and energy.....or go for the dam........both ways you got something to gain and lose.....imho we have to build the dam and we got much more than we would lose.......besides considering technology is developing real faster now......something we used to think we cant handle can be sorted out now or at least in the near future.....
