    This is the reason why not many plants have been built scince the 70's but also because of the risk that are associated with nuclear power. If there is a disaster there is enough nuclear power to kill an entire city not even mentioning the enviromental effects.
    A nuclear power plant produces electricity in almost exactly the same way that a conventional (fossil fuel) power plant does. A conventional power plant burns fuel to create heat. The fuel is generally coal, but oil is also sometimes used. The heat is used to raise the temperature of water, thus causing it to boil. The high temperature and intense pressure steam that results from the boiling of the water turns a turbine, which then generates electricity. A nuclear power plant works the same way, except that the heat used to boil the water is produced by a nuclear fission reaction using 235U as fuel, not the combustion of fossil fuels. A nuclear power plant uses much less fuel than a comparable fossil fuel plant. A rough estimate is that it takes 17,000 kilograms of coal to produce the same amount of electricity as 1 kilogram of nuclear uranium fuel.
    Nuclear power in china
    Mainland China has 13 nuclear power reactors in operation, more than 25 under construction, and more about to start construction soon.
    Additional reactors are planned, including some of the world's most advanced, to give more than a ten-fold increase in nuclear capacity to at least 80 GWe by 2020, 200 GWe by 2030, and 400 GWe by 2050.
    China is rapidly becoming self-sufficient in reactor design and construction, as well as other aspects of the fuel cycle.
    Most of mainland China's electricity is produced from fossil fuels (80% from coal, 2% from oil, 1% from gas in 2006) and hydropower (15%)
    In September 2010, the China Daily reported that China National Nuclear Corporation (CNNC) alone plans to invest CNY 800 billion ($120 billion) into nuclear energy projects by 2020. Total investment in nuclear power plants, in which CNNC will hold controlling stakes, will reach CNY 500 billion ($75 billion) by 2015
    This investment shows that there is development of nuclear power plants. The disaster in Japan has discouraged China from increasing their nuclear energy however. This goal that they wish to reach by 2020 may be cancled because based on research the risk is not worth the reward. I for see china ending this process.

    The PRC government has adopted policies which promote the generation and use of clean and renewable energy, including hydroelectric power. In terms of hydroelectric power, the policies are particularly favorable for small hydroelectric power projects. Hydroelectric power has also been granted the highest priority for power dispatch by the PRC central government.
    China is seeking to significantly reduce its carbon emissions by 2020, by reducing its reliance on coal-fired power projects and factories.

    In constructing the massive dam on the Yarlun Zangbo the Chinese met a crucial turning point in the future of their energy production
    The Yarlung Zangbo, with its rushing water, is the last of the great rivers in China that remains dam free, that is all about to change. On the 12th of November 2010, the damming of the river was made public.

    In 2002, Chen published a paper in Engineering Sciences, in whihc he looked at the positive impact that a hydropower station at the Great Bend would have on electric generation in Asia. Even if there were financial issues, funds could be raised both domestically and abroad, and that electricity could be exported to south-east Asia. He Xiwu said: “I’ve heard there is still no plan for the Great Bend. The state should spend a bit every year on long-term research. There’s 38-gigawatts of potential there, but the geology is complicated and construction would be difficult. It has to be done carefully.”
    China has been extremely cautious about building hydropower projects on the Nu River, or the Salween, in the southwestern Yunnan Province, Yunnan's Party chief Bai Enpei said Wednesday.

    The Zangmu hydroelectric power station in which about 7.9 billion yuan or $1.2 billion is being inveasted is being built on the middle section of the Yarlung Zangbo river between the countries of Sangri and Gyaca. This plant will be located in a V-shaped valley 3,200 metres above sea level. This plant produces 510 megawatts, which makes it much smaller than the 18,000-megawatt Three Gorges Dam.

    China has been extremely cautious about building hydropower projects on the Nu River, or the Salween, in the southwestern Yunnan Province, Yunnan's Party chief Bai Enpei said Wednesday.
    Bio-diversity and environment in the upper reaches of the river is considered highly valuable but fragile, which has resulted in heated debates over hydropower development on the river.
    While increasing, China's per capita consumption of electricity is still low compared to other countries. According to NationMaster, China's consumption of electricity was 2,179.5 kWh per capita in 2006, compared to 7,702.0 kWh per capita for Japan, 9,593.6 kWh per capita for Taiwan and 12,343.1 kWh per capita for the United States. with one of the fastest growing population world-wide, the amount of power necessary to feed china is growing exorbitantly.

    China has an abundance of water resources that can be utilized for hydroelectric generation. In 2005 China was only utilizing 19% of its economicaly exploitable resouces, compared to 67% for Canada and 42% for Brazil, according to calculations based on data provided by the World Energy Council.

    Natural gas is already used in American homes today and technology is being created to make natural gas a more viable option for use in automobiles.
    Another exciting aspect of natural gas is that it can be extracted from landfills that produce large amounts of methane. This prospect of capturing the pollutants coming from landfills would not only be a good source of fuel but can also cut down on the pollutants being directly released into the atmosphere.
    In countries like China the demand for natural gas has increased considerably. In the 1990's Chinas gas program increased in size by alot with the development of the Ordos gas field. The pipeline extends 865 kilometers and transports 2.8 billion meters^3 of natural gas per year.
    China has also moved towards building that can be completely powered by natural gas. In Shanghai an energy source restructuring project was launched that prohibited the construction of coal powered buildings and promoted the construction of natural gas powered buildings.
    This expanding market has made room for more than 60 natural gas companies to spring up in china
    Coal accounts for at least 70% of china's energy right now and as a nation it is trying to ween itself off of this fossil fuel by supporting the natural gas companies so that in the near future its dependence on coal can be lessened.
