China's Tibet Megadam hydro power project takes 10 years, cost $170 billion

American logistic expert reports from China video: China's Tibet Megadam hydro power project takes 10 years, cost $170 billion to produce equivalent to annual supply of UK electrical energy at 1/5 the cost. 美國物流專家從中國發來的視訊報告：中國的西藏水力發電計畫耗時10年，耗資1,700億美元，是英國1/5的成本提供相當於英國一年的電力供應.

Engineers have begun work on the world's largest hydroelectric project, in China's Xizang.

While the topography of the region is ideal for large-scale hydro, they face enormous challenges. The area is remote, the canyon walls are steep and narrow, and it sits in an active earthquake zone. The project will take a decade to bring online, and will cost $170 billion to complete.

But in the context of comparable new power projects globally, $170B is a relative bargain. When complete, the new dam will generate the equivalent of one Great Britain's worth of electric power, every year, and further push down China's already low energy costs for households and industries.

工程師們已開始在中國西藏啟動世界上最大的水力發電計畫。

儘管該地區的地形非常適合大規模水力發電建設，但他們面臨著巨大的挑戰。該地區地處偏遠，峽谷陡峭狹窄，並且位於活躍地震帶。該項目將耗時十年才能建成，耗資1700億美元。

但與全球同類新建電力項目相比，1,700億美元相對划算。建成後，這座新大壩每年將產生相當於一個英國的電力，這將進一步降低中國本已較低的家庭和工業能源成本.
